Area is the amount of space that a two-dimensional shape takes up. It is measured in square units, such as square feet (ft^2), square yards (yd^2), or square meters (m^2).
To calculate the area of a rectangle, multiply the length by the width.
Area of a rectangle = length * width
To calculate the area of a square, multiply the side length by itself.
Area of a square = side length * side length
To calculate the area of a triangle, multiply the base by the height and divide by 2.
Area of a triangle = base * height / 2
Perimeter is the total length of all the sides of a two-dimensional shape. It is measured in linear units, such as feet (ft), yards (yd), or meters (m).
To calculate the perimeter of a shape, add up the lengths of all the sides.
Perimeter of a shape = sum of the lengths of all the sides
Example:
To calculate the area and perimeter of the rectangle in question #4, we would use the following formulas:
Area = length * width = 5 yd * 72 yd = 360 yd^2
Perimeter = sum of the lengths of all the sides = 5 yd + 72 yd + 5 yd + 72 yd = 30 yd
Answers to the remaining questions:
#5:
Area = 45 yd^2
Perimeter = 22 yd
#6:
Area = 87 yd^2
Perimeter = 30 yd

The moon has a radius of about 939 leagues long. What is the total surface area of the moon? Rounded to the nearest whole number. (Ex. 3244.55 rounds up to 3245.) *
Answers
Radius, r = 939 ft
Then:
Diameter, d = 1878 ft
Circumference, C = 5899.9110034416 ft
Area, A = 2770008.2161158 ft^2
AREA = 2770 if you're shortening.
For this case we assume that the moon is spherical. For definition, the surface area of a sphere is given by:

So, we start with x0 = 2 and we plug that into the base equation:
x0 = 2 ==> f(x) = 2(2) = 4
x1 = 4 ==> f(x) = 2(4) = 8
x2 = 8 ==> f(x) = 2(2) = 16

By visual inspection, determine the best fitting regression model for the data below
Answers
Answer:
A) Quadratic
Step-by-step explanation: It has the U shape of a parabola which a quadratic equation has.
Answer:
The correct option is A.
Step-by-step explanation:
In a scatter plot the best fit curve in known as regression curve. Types of regression curves are
1. Linear regression line : If the best fit of a data is a straight line, then it is known as linear regression line.
2. Quadratic regression : If the best fit of a data is a U-shape curve, then it is known as quadratic regression.
3. Exponential regression : If the best fit of a data is an exponential curve, then it is known as exponential regression.
From the given graph it is clear that scatter data forms a U-shaped curve. Since the best fit of a data is a U-shape curve, therefore the quadratic regression model is best for the data.
Thus, option A is correct.

y intercept form of a line is represented by y = mx + c
Where m = slope of the line and c = y- intercept of the line.
A line passing through two points (2, 5) and ( 6, 7) has the slope
m = [tex]\frac{y-y'}{x-x'}[/tex]
= [tex]\frac{7-5}{6-2}[/tex]
= [tex]\frac{2}{4}[/tex]
= [tex]\frac{1}{2}[/tex]
Equation will be y = [tex]\frac{x}{2}+c[/tex]
This line passes through (2, 5)
5 = [tex]\frac{1}{2}\times 2+c[/tex]
c = 5 - 1
c = 4
And the equation will be y = [tex]\frac{1}{2}x+4[/tex]
Since a point (k 11) passes through the line then we will plug in these values in the equation to find the value of k.
11 = [tex]\frac{1}{2}\times k+4[/tex]
11 - 4 = [tex]\frac{k}{2}[/tex]

The number of horses occupying stalls at the county fairgrounds can be modeled by the following function, where x represents the number of days since the first of June.
h(x)=-3x^2+30+225
Rewrite this function in the form that reveals when there are no horses occupying stalls at the fairgrounds
Answers
Answer:
The equation is -3x^2 + 30x + 225 = 0, and the number of days is 15.
Step-by-step explanation:
I assume an x is missing, and the function is h(x) = -3x^2 + 30x + 225
You want to know the number of days in which the function value is zero.
-3x^2 + 30x + 225 = 0
Divide both sides by -3.
x^2 - 10x - 75 = 0
(x - 15)(x + 5) = 0
x - 15 = 0 or x + 5 = 0
x = 15 or x = -5
We discard the negative solution.
Answer: The equation is -3x^2 + 30x + 225 = 0, and the number of days is 15.
Answer:
h(x) = -3 (x + 5) (x - 15)
Step-by-step explanation:
h(x) = -3x^2 + 30 + 225
= -3(x^2 - 10x - 75)
= -3(x + 5)(x - 15)
x = -5 x = 15
If p varies directly as r and p=4,r=2,what the value of r when p=12
Answers
Answer:
r = 6
Step-by-step explanation:
Given that p varies directly as r, then the equation relating them is
p = kr ← k is the constant of variation
To find k use the condition p = 4, r = 2
k = [tex]\frac{p}{r}[/tex] = [tex]\frac{4}{2}[/tex] = 2
p = 2r ← equation of variation
When p = 12
12 = 2r ( divide both sides by 2 )
hence r = 6

Step-by-step explanation:
Note that 3*x + 9 = 3*x if you choose to put the expression 3*x on the right side of the expression.
To solve this equation, you subtract 3 * x on both sides of the equation, obtaining:
3*x+9-3*x=3*x-3*x
9=0
You get 9 = 0. This expression cannot be true regardless of the value taken by x. You can tell then that in this case the equation has no solution.

3w - 4z = 8 what is w
Answers
Final answer:
To solve the equation 3w - 4z = 8 for w, add 4z to both sides and then divide by 3, resulting in the expression w = (4z + 8) / 3.
Explanation:
The student's equation, 3w - 4z = 8, involves algebraic manipulation to solve for the variable w. To isolate w, we rearrange the equation to get w by itself on one side of the equation:
Add 4z to both sides to get: 3w = 4z + 8
Divide both sides by 3 to solve for w: w = (4z + 8) / 3
Now we have w expressed in terms of z. This is the solution for w assuming you have a specific value for z you can substitute into this expression.
Final answer:
To find w, isolate it by adding 4z to both sides and then dividing by 3, resulting in w = (8 + 4z) / 3.
Explanation:
To solve for w in the equation 3w - 4z = 8, you would isolate w on one side of the equation. First, add 4z to both sides of the equation so that you have 3w = 8 + 4z. Then, divide both sides by 3 to get w by itself. The final equation representing w would be w = (8 + 4z) / 3. This doesn't directly correspond to the provided physics equations; however, we can apply a similar method of isolating the unknown in those as well.

A school determined that there is about a 33% chance that a student will choose a salad over a grilled chicken sandwich for lunch. Which simulation could you use to answer questions about the type of lunch students will choose?
Answers
A Monte Carlo simulation can be used to answer questions about the type of lunch students will choose.
Explanation:A simulation that could be used to answer questions about the type of lunch students will choose is a Monte Carlo simulation.
In this simulation, the probability of a student choosing a salad over a grilled chicken sandwich is represented by a random number generator.
Each time the simulation is run, a random number between 0 and 1 is generated, and if the number is less than or equal to 0.33, it is considered a salad choice. This process is repeated multiple times to generate a distribution of lunch choices.
By analyzing the distribution, you can estimate the likelihood of students choosing a salad over a grilled chicken sandwich.
Final answer:
A simulation to model the 33% chance of students choosing a salad over a grilled chicken sandwich could involve a random generator where the number 1 (out of 1 to 3) represents the choice of a salad, simulating the probability accurately.
Explanation:
To simulate the situation where there is a 33% chance that a student will choose a salad over a grilled chicken sandwich for lunch, you could use a simple random process to model this probability. You might simulate the choice by using a random number generator set to generate numbers from 1 to 3, where one of the numbers (say 1) represents choosing a salad, and the other two numbers (2 and 3) represent choosing a grilled chicken sandwich. Every time the number 1 comes up, it would count as a 'success', representing a student choosing a salad. You could run this simulation a large number of times to answer questions about the likelihood of various outcomes related to the students' lunch choices.

We are given the following system of equations and we are to tell if the system has one solution, infinite solution, many solutions or no solutions:
[tex]5x-3y=10[/tex] --- (1)
[tex]10x+6y=20[/tex] --- (2)
If we take the common out from (2), we get:
[tex]2(5x+3y) = 20 [/tex]
[tex]5x+3y = 10 [/tex] --- (3)
So adding the two equations (1) and (3) gives 10x=20 ⇒ x=2.

Madison currently has a balance of 5503.51 ina an account earning simple interest. 19 years ago she opend up an account with an intial deposit of 3196. What is the interest rate on the account o
Answers
Answer:
The simple interest is 3.80% per year.
Step-by-step explanation:
We are presented with a simple interest problem and the following information has been availed;
Accumulated amount = 5503.51
Time = 19 years
Principal = 3196
The first step is to determine the total interest earned over the entire time period;
Interest = Amount - Principal
= 5503.51 - 3196
= 2307.51
The simple interest formula states the total interest earned is equal to the product of the principal, the interest rate and the time;
[tex]I=\frac{P*R*T}{100}[/tex]
Making R the subject of the formula yields;
[tex]R=\frac{100*I}{P*T}[/tex]
Substituting the values we have and simplifying;
[tex]R=\frac{100*2307.51}{3196*19}=3.80[/tex]
The simple interest is thus 3.80% per year.
What is the next term in -2, -5, -9, -14, -20.
And why
Answers
The next term would be -27
Lets pretend that all the negative signs went away, that way you have the data:
2, 5, 9, 14, 20
^^^In my opinion it just makes it easier because I don't like negative numbers. Keep in mind that the negatives are still there but I just made them "Invisible"
The pic below is how I found the pattern. If you can't tell by the picture from 2 to 5 it increases by 3. From 5 to 9 it increases by 4. From 9 to 14 it increases by 5. From 14 to 20 it increases by 6.
This means the pattern is to increase the number 1 more then the amount the previous number was increased (keep in mind this is the pattern for the positive version and therefore the original pattern would be decreasing (since the bigger a number that is negative is, the farther away it gets from zero, therefor getting smaller.) For the original version the rule would be: it would decrease the number 1 more then the amount the previous number was decreased) <<<Hope that makes sense
That means that 20 will be increased by 7 ( 6+ 1 = 7). Which equals 27. Make the negative sign visible again and your answer is -27.
Let me know if this made sense and if it was helpful!
a pool in the sape of a rectangle has a perimeter of 80 feet. the pool is 8 feet less wide than it is long. find the length and width of the pool
Answers
Answer:
Length: 28 ft Width: 12 ft
Step-by-step explanation:
So to solve this, we know that perimeter means the sum of all the lengths added together. And we can start by dividing 80 by 4.
80 ÷ 4 = 20
And now, the width must be eight feet less than the length, meaning we just subtract eight from the width, and add eight to the length.
20 - 8 = 12
20 + 8 = 28
L = 28
W = 12
And now we can double check:
12+ 28 + 12 + 28 = 80
