Answer:
14 free throw baskets , 25 two point baskets and 11 three point baskets
Step-by-step explanation:
Let n₁ represent the number of free-throw baskets, n₂ represent the number of two point baskets and n₃ represent the number of three point baskets.
Now, from the question, the number of two point baskets, n₂ is greater than the free throw baskets by 11. This is written as n₂ = n₁ + 11. Also, the number of three point baskets n₃ is three less than the number of free point baskets. This is written as n₃ = n₂ - 3. Since our total number of points equals 97, it follows that, sum of number of points multiplied by each point equals 97. So, ∑(number of points × each point) = 97. Thus,
n₁ + 2n₂ + 3n₃ = 97. Substituting n₂ and n₃ from above, we have n₁ +2(n₁ + 11) + 3(n₁ - 3) = 97.
Expanding the brackets, we have, n₁ + 2n₁ + 22 + 3n₁ - 9 = 97
collecting like terms, we have 6n₁ + 13 = 97
6n₁ = 97 - 13
6n₁ = 84
dividing through by n₁ we have, n₁ = 84/6 =14
so n₁ our free throw baskets equals 14. Substituting this into n₂ our number of two point baskets equals n₂ = n₁ + 11 = 14 + 11 = 25. Our number of three point baskets n₃ = n₁ - 3. So, n₃ = 14 -3=11
Final answer:
To find the combination of scores for Team A's 97 points, we define variables for each scoring method, set up equations based on the given relationships, and solve to find that Team A made 10 free throws, 21 two-point baskets, and 13 three-point baskets.
Explanation:
In a basketball game where Team A scored 97 points by a combination of two-point baskets, three-point baskets, and one-point free throws, we can define the following variables based on the information given: Let x represent the number of free throws, y the number of two-point baskets, and z the number of three-point baskets. From the statements, we know that y = x + 11 and x = z - 3. The total points can be represented by the equation: 1x + 2y + 3z = 97.
Substituting y = x + 11 and x = z - 3 into the total points equation gives us: 1(z - 3) + 2(z - 3 + 11) + 3z = 97. Simplifying this equation gives 6z + 17 = 97, leading to 6z = 80, and thus z = 13.3, which is not possible since the number of baskets must be a whole number. Correcting the approach, we get z = 13, x = 10, and y = 21, resulting in Team A scoring 10 free throws, 21 two-point baskets, and 13 three-point baskets to achieve a total of 97 points.
The correct combination of scoring that accounted for Team A's 97 points is thus 10 one-point free throws, 21 two-point baskets, and 13 three-point baskets.
The recommended angle for a wheel chair ramp is 5 degrees. If the rise of the ramp to go up the steps is 2 feet, find the horizantal run length that the ramp must start. (Round to one decimal place)
wheel chair ramp
Answer:
22.9 feet
Step-by-step explanation:
You are using Tangent because you have the opposite and adjacent sides
Tan 5 = 2/x
x Tan 5= 2
x= 2/Tan5
= 22.860
To find the horizontal run length of a wheelchair ramp with a 5-degree angle and a 2-foot rise, use the tangent function of trigonometry. Plug the given values into the tangent formula, rearrange to solve for 'Run', and calculate to get a run length of approximately 22.8 feet.
Explanation:The question is referring to the use of trigonometry to solve real-life problems. Here, we are going to use the tangent of the angle, which is defined as the ratio of the opposite side (the rise) to the adjacent side (the run). In this case, we know that the angle is 5 degrees and the rise is 2 feet.
In mathematical terms, this can be written as:
Tan(ρ) = Rise/Run
Substituting the values into the equation, we get:
Tan(5°) = 2/Run
Solving for Run, we get:
Run = 2/Tan(5°)
You can find this value using a calculator, rounding to the nearest tenth, to get the run as approximately 22.8 feet.

For a project on Egypt, Nick is building a paper model of a square based pyramid. The square base measures 8 inches by 8 inches. The slant height is 10 inches. Which measurement BEST describes the amount of construction paper needed to make this pyramid? (round to nearest whole number)
Answer:
Step-by-step explanation:
The square base measures 8 inches by 8 inches. The slant height is 10 inches.
The formula for determining the area of the square base of the pyramid is l^2. Therefore,
Area of the base = 8^2 = 64 inches^2
The formula for determining the perimeter of the square base is
4l. It becomes
4 × 8 = 32 inches
The amount of construction paper needed to make this pyramid is the total surface area of the pyramid. Therefore,
Total surface area = (1/2 × 32 × 10) + 64
= 160 + 64 = 224 inches^2
Nick will need approximately 224 square inches of construction paper for his square based pyramid project with a base measuring 8 inches by 8 inches and a slant height of 10 inches.
Explanation:To find the amount of construction paper needed for Nick's square based pyramid project, we need to calculate the surface area of the pyramid. The surface area of a pyramid includes the area of the base plus the area of the four triangular sides.
The area of the base (Abase) is the side length squared:
Abase = side × side = 8 inches × 8 inches = 64 square inches.
The area of one triangular side (Atriangular side) is given by the formula:
Atriangular side = 1/2 × base × slant height.
For Nick's project, the base of a triangular side is equal to the side of the square, so:
Atriangular side = 1/2 × 8 inches × 10 inches = 40 square inches.
Since there are four identical triangular sides:
Total area of triangular sides = 4 × 40 square inches = 160 square inches.
Adding the base and triangular sides areas together gives us the total construction paper needed:
Total construction paper needed = Abase + Total area of triangular sides = 64 square inches + 160 square inches = 224 square inches.
Therefore, Nick will need approximately 224 square inches of construction paper for his project. To get the nearest whole number, we round 224 to 224.
The combined height of one oak tree and one pine tree is 21 meters. The height of 4 oak trees stacked on top of each other is 24 meters taller than one pine tree. How tall is the oak tree and the pine tree
Answer:
Height of an oak tree= 9 meters
Height of a pine tree = 12 meters
Step-by-step explanation:
Given:
The combined height of 1 oak tree and 1 pine tree = 21 meters
Height of 4 oak trees = 24 meters more than 1 pine tree
To find the height of 1 pine tree and height of one oak tree.
Solution:
Let the height of one oak tree be = [tex]x[/tex] meters.
Let height of one pine tree = [tex]y[/tex] meters.
Combined height can be given as :
[tex]x+y=21[/tex]-------------[1]
Height of 4 oak trees = 24 meters more than 1 pine tree
The above statement can be given as :
[tex]4x=24+y[/tex]------------[2]
Rearranging equation [2] by subtracting both sides by [tex]y[/tex].
[tex]4x-y=24+y-y[/tex]
[tex]4x-y=24[/tex]-------------[2]
Adding rearranged equation [2] to [1].
[tex]x+y=21[/tex]
[tex]4x-y=24[/tex]
+--------------------
[tex]5x\ = 45[/tex]
Dividing both sides by 5.
[tex]\frac{5x}{5}=\frac{45}{5}[/tex]
∴ [tex]x=9[/tex]
Plugging in [tex]x=9[/tex] in equation [1]
[tex]9+y=21[/tex]
Subtracting both sides by 9.
[tex]9-9+y=21-9\\\therefore y=12[/tex]
Height of an oak tree= 9 meters
Height of a pine tree = 12 meters

You are asked to draw a triangle with side lengths of 8 inches and 10 inches. What is the longest whole number length that your third side can be? Group of answer choices 18 20 16 21
Answer:
Correct number : c = 16
Step-by-step explanation:
The triangle theorem states that each side of the triangle is smaller than the sum of the other two and larger than their difference. We denote the three sides of a triangle as a, b, and c.
Suppose that a = 8 and b = 10 and as we see b is greater than a , b > a
b - a < c < b + a => 10 - 8 < c < 10 + 8 => 2 < c < 18
from the offered answers we choose number 16
c = 16
God is with you!!!
Answer:
Step-by-step explanation:
if a,b,c are three sides of a triangle,then a<b+c,b<c+a,c<a+b
or in general we can say any side < sum of other two sides.
third side<8+10
or third side <18
Here third side=16
if you are asked smallest side then any side >difference of other two sides.
third side >10-8 or>2

A 25-foot ladder rests against a building. The base of the ladder is 15 feet away from the base
of the building. At what height does the ladder rest on the building?
Answer: the top of the ladder is 20ft below the ground.
Step-by-step explanation:
The ladder makes an angle, θ with the ground thus forming a right angle triangle with the wall of the house.
The length of the ladder represents the hypotenuse of the right angle triangle.
The ground distance between the base of the house and the base of the ladder represents the adjacent side of the right angle triangle.
Therefore, to determine the height at which the ladder rest on the building, x, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
25² = x² + 15²
625 = x² + 225
x² = 625 - 225 = 400
x = √400 = 20 ft
Levi wants to order the fractions 1/3, 2/5, and 11/30 in descending order? How can you help him by using a common denominator? Explain and order the fractions in descending order.
Answer:
The correct order of fractions in descending order will be:
[tex]\frac{2}{5}, \frac{11}{30}, \frac{1}{3}[/tex]
Step-by-step explanation:
Given fraction:
[tex]\frac{1}{3}, \frac{2}{5}, \frac{11}{30}[/tex]
To arrange them in descending order.
Solution:
In order to arrange the fractions in descending order, we will have to find the least common denominators.
To find the least common denominator, we will find the least common multiple of the denominators 3,5, and 30.
Since 30 is a common multiple of all 3 numbers, so it will be the least common denominator.
So, we multiply the numerators and denominators with same numbers in order to make the denominators = 30.
So, we have:
[tex]\frac{1}{3}, \frac{2}{5}, \frac{11}{30}[/tex]
⇒ [tex]\frac{1\times 10}{3\times 10}, \frac{2\times 6}{5\times 6}, \frac{11\times 1}{30\times 1}[/tex]
⇒ [tex]\frac{10}{30}, \frac{12}{30}, \frac{11}{30}[/tex]
Now, we compare the numerators and arrange them accordingly.
[tex]\frac{12}{30} > \frac{11}{30} > \frac{10}{30}[/tex]
So, the correct order of fractions in descending order will be:
[tex]\frac{2}{5}, \frac{11}{30}, \frac{1}{3}[/tex]

Tito receives a weekly salary of $350 at an appliance store. He also receives a 5% commission on a total dollar amount of all sales he makes. What must his total sales be in a week if he is to make a total of $675
Answer:his total sales be $6500 in a week if he is to make a total of $675
Step-by-step explanation:
The total amount of money that Tito receives as weekly salary at an appliance store is $350.
He also receives a 5% commission on a total dollar amount of all sales he makes.
Let x represent his total sales in a week.
The amount of commission that he receives would be
5/100 × x = 0.05x
if he is to make a total of $675 in a week, it means that
0.05x + 350 = 675
0.05x = 675 - 350 = 325
x = 325/0.05 = $6500
By setting up an equation to represent Tito's total earnings and solving for total sales, we find that Tito must make $6500 worth of sales to earn a total of $675 in a week.
Explanation:The subject of this question is Mathematics, specifically dealing with algebraic calculations to find the value of the variable. The variable in this case is the total sales Tito must make to earn a total of $675 in a week.
We know that Tito earns a fixed weekly salary of $350 and he also receives a 5% commission on his total sales. He wants to know how much he needs to sell to reach a total earning of $675.
To solve this, we set up an equation to represent the total earnings that Tito wishes to make: $350 (salary) + 0.05x (sales commissions) = $675.
Now we solve the equation for x (total sales). First, subtract $350 from both sides to get 0.05x = $675 - $350, which simplifies to 0.05x = $325.
Next, divide both sides of the equation by 0.05 to find x, so x = $325 / 0.05.
Therefore, Tito's total sales in a week must be $6500 for him to make a total of $675.

6 hrs $120
A) $16
B) $20
C) $28
D) $40
Answer:
D) $40
Step-by-step explanation:
We need to find the DIFFERENCE between Susan's and Jim's lawn care business in the amounts they charge for 10 hours at work.
Solution:
First we will find the hourly charges of lawn care for both.
Given:
From the table of Jim we can see that
Charges of Jim for 1 hour = $20
So for 10 hour = Charges of Jim for 10 hour.
By using Unitary method we get;
Charges of Jim for 10 hour = [tex]10\times 20 =\$200[/tex]
Now From table of Susan we can see that;
for 2 hours = $48
So for 1 hour = Charges of Susan for 1 hour.
By Using Unitary method we get;
Charges of Susan for 1 hour = [tex]\frac{48}{2}= \$24[/tex]
Now we know that;
Charges of Susan for 1 hour = $24
So for 10 hour = Charges of Susan for 10 hour
again by using Unitary method we get;
Charges of Susan for 10 hour = [tex]24\times10 =\$240[/tex]
Now we need to find the difference between their charges.
Difference can be calculated by subtracting Charges of Jim for 10 hour from Charges of Susan for 10 hour.
framing in equation form we get;

Plan A is a flat rate of $50 per month unlimited data. Plan B is zero dollars per month but you pay five dollars per gigabyte of data used. If you average about 6 GB of data used per month, which option will be least expensive?
Answer:
B
Step-by-step explanation:
For Plan A ---> you pay $50 per month flat
For Plan B,
average usage = 6 GB
cost per GB = $5 per GB
average cost per month = $5 per GB x 6 GB = $30
comparing the cost per month between the 2, we can clearly see that for plan B, $30 a month is the least expensive option
Plan B would be the least expensive option for someone who uses about 6 GB of data per month, costing $30, compared to Plan A's flat rate of $50 per month. It is important to also consider other costs and usage patterns when selecting a phone data plan.
When finding the least expensive phone data plan between a flat rate plan and a pay-per-gigabyte plan, you need to calculate the total costs based on the average data usage. In this case, Plan A offers unlimited data for a flat rate of $50 per month, while Plan B charges $5 per gigabyte of data used, with no monthly base cost.
For an average use of 6 GB of data per month:
Plan A would cost $50 every month, regardless of how much data you use.
Plan B would be 6 GB x $5/GB = $30 per month.
Comparing the two plans, Plan B is the least expensive option for someone who uses about 6 GB of data each month, as it would cost $30 as opposed to the $50 charged by Plan A.
However, it's important to consider your personal usage patterns and other potential costs, such as monthly charges for other services, occasional charges for peripherals or repairs, and any relevant annual costs or major costs when choosing a plan that fits your budget effectively.

A cell phone company charges a monthly fee plus $.25 for each text message. The monthly fee is $30 and you owe $59.50. How many text messages do you have?
Answer: you have 118 text messages.
Step-by-step explanation:
Let x represent the number of text messages that you have or sent.
A cell phone company charges a monthly fee plus $.25 for each text message. The monthly fee is $30. This means that the total cost of x sending x messages in a month would be
0.25x + 30
If you owe $59.50, then your total cost is $59.50
Therefore,
59.50 = 0.25x + 30
0.25x = 59.50 - 30
0.25x = 29.5
x = 29.5/0.25
x = 118

The popcorn stand sells only soft drinks and popcorn, and only one size of each. In fact, the same cup is used for both products this is part of the stand's "sales pitch. "A soft drink cost $2.00 and a popcorn cost $4.00. On a certain day, 120 cups were used and $330.00 was collected. How many soft drinks and how many popcorns were sold on that day? Use a system of equations approach to find your answer. Show all work.
Answer:
On that day 75 soft drinks and 45 popcorn were sold.
Step-by-step explanation:
Given:
Let the number of soft drinks be 'x'.
Let the number of popcorn be 'y'.
Number of cups sold = 120
Now we know that;
Number of cups sold is equal to sum of the number of soft drinks and the the number of popcorn.
framing in equation form we get;
[tex]x+y=120 \ \ \ \ equation \ 1[/tex]
Also Given:
Cost of Soft drink = $2 .00
Cost of popcorn = $4.00
Total amount collected = $330.00
Now we know that;
Total amount collected is equal to sum of the number of soft drinks multiplied by Cost of Soft drink and the number of popcorn multiplied Cost of popcorn.
framing in equation form we get;
[tex]2x+4y = 330 \ \ \ \ eqaution \ 2[/tex]
Hence The System of equation to determine the number of softdrinks and cups sold is [tex]\left \{ {{x+y=120} \atop {2x+4y=330}} \right.[/tex].
Now to find the number of each type of cups sold we will solve the above equations.
First we will multiply equation 1 with 2 we get;
[tex]2(x+y)=120\times2\\\\2x+2y =240 \ \ \ \ equation \ 3[/tex]
Now we will subtract equation 3 from equation 2 we get;
[tex]2x+4y-(2x+2y)=330-240\\\\2x+4y-2x-2y=90\\\\2y = 90[/tex]
Now Dividing both side by 2 we get;
[tex]\frac{2y}{2}= \frac{90}{2}\\\\y=45[/tex]
Now we will substitute the value of 'y' in equation 1 we get;
[tex]x+y=120\\\\x+45 =120\\\\x=120-45 = 75[/tex]
Hence On that day 75 soft drinks and 45 popcorn were sold.
A truck can be ready for company a 420 dayPlus $.30 per mile can we be charges $50 a day plus $.50 per mile to rent the same truck find the number of miles in a day at which the rental costs for a company a and Company B same
Answer:it will take 1850 miles
Step-by-step explanation:
Let x represent the number of miles in a day at which the rental costs for a company A and Company B same.
Let y represent the total cost of renting the truck for x miles with company A.
Let z represent the total cost of renting the truck for x miles with company A.
Company A charges $420 a day Plus $.30 per mile. This means that
y = 420 + 0.3x
Company B charges $50 a day plus $.50 per mile to rent the same truck. This means that
z = 50 + 0.5x
To determine the number of miles in a day at which the rental costs for a company A and Company B same, we will equate y to z. It becomes
420 + 0.3x = 50 + 0.5x
0.5x - 0.3x = 420 - 50
0.2x = 370
x = 370/0.2 = 1850 miles
The length of Martin's driveway, rounded to the nearest foot, is 121 ft. What is the minimum possible length of the driveway? A 121.0 ft B 120.5 ft C 120.9 ft D 120.3 ft
Answer:
B. 120.5 ft
Step-by-step explanation:
Given:
Length of Martins drive way = 121 ft
We need to find the minimum possible length of the driveway
Solution:
Now we know that ;
When a number is rounded to nearest whole number.
We can say that the number is in decimal format.
Also rounding techniques applies when the decimal number has digit 5 or more in ten's place after decimal then the number in increase by 1 as a whole number.
Here the number is rounded to nearest foot which is 121 ft.
So we an say that;
Number ranging from 120.50 to 120.99 can be made to 121 as nearest foot.
Hence the minimum possible length of the drive way could be 120.5 ft
Two hunters started to walk towards each other simultaneously from two different locations in the forest. The distance between them was 21 miles. The first hunter walked at a rate of 4 mph, while the second one walked at a rate of 3 mph. The first hunter took a dog with him, who ran at an average rate of 5 mph. The dog started to run towards the second hunter, met him and ran back to the first hunter. The dog repeated this until the two hunters met each other. How many miles did the dog run?
Answer:
The dog ran 15 miles
Step-by-step explanation:
The combined speed of the 2 hunters is 7mph, therefore, they will met in 21/7 = 3 hours, becuse they are walking in opposite directions. In this 3 hours the dog kept running and thus it ran 3*5 = 15 miles. Note that the position of the dog is always between the position of both hunters, therefore when both hunters met each other, the dog will be alredy there.
Find the distance between the pair of points given on the graph
Answer: distance = 5
Step-by-step explanation:
The formula for determining the distance between two points on a straight line is expressed as
Distance = √(x2 - x1)² + (y2 - y1)²
Where
x2 represents final value of x on the horizontal axis
x1 represents initial value of x on the horizontal axis.
y2 represents final value of y on the vertical axis.
y1 represents initial value of y on the vertical axis.
From the graph given,
x2 = 1
x1 = - 2
y2 = 0
y1 = - 4
Therefore,
Distance = √(1 - - 2)² + (0 - - 4)²
Distance = √3² + 4² = √9 + 16 = √25
Distance = 5
