A cone-shaped tent has a diameter of 12 ft and a height of 6 ft. What is the approximate volume of the tent? Question 2 options: 226 ft3 679 ft3 905 ft3 2714 ft3
The volume of the tent is option A) 226 ft³
Step-by-step explanation:
The given data are,
A cone-shaped tent has a diameter of 12 ft.The height of the cone is 6 ft.To find the volume of the tent :
The volume of the tent can be found using the formula for volume of the cone, since the tent is in the shape of a cone.
Volume of the cone = (1/3)πr²h
where, r is the radius of the cone. The diameter is given as 12 ft. Therefore, to find the radius = diameter /2 = 12/2 = 6 ft.
The radius, r = 6 ft.
The height h of the cone is h= 6 ft.
Volume of the cone = (1/3)× 3.14× 6²× 6.
⇒ (1/3)× 3.14× 216
⇒ 678.24 / 3
⇒ 226.08 (which is approximately 226)
⇒ 226 cubic. ft
Therefore, the volume of the tent is option A) 226 ft³

Step-by-step explanation:
A square and a regular hexagon have side of the same length. The perimeter of the square increased by 48 units will be equal to the perimeter of the hexagon. What is the x, the length of the side of the hexagon or square
The length of the side of the hexagon or square is 24 units.
Step-by-step explanation:
It is given that, a square and a regular hexagon have side of the same length.
The length is not given in the problem. So, let us assume the length of the side of hexagon or square as 'x'.
The additional information given is that, the perimeter of the square increased by 48 units will be equal to the perimeter of the hexagon.
The perimeter of the square = 4 × length of the side.Then, the perimeter of the square increased by 48 units = (4x + 48).The perimeter of the hexagon = 6 × length of the side.Therefore, the perimeter of the hexagon = 6x.To calculate the length x of square and hexagon :
Comparing both the perimeters of square and hexagon,
⇒ (4x + 48) = 6x
⇒ 48 = 6x-4x
⇒ 2x = 48
⇒ x = 48/2
⇒ x = 24 units.
The length of the side of the hexagon or square is 24 units.
if the polygon shown below is a regular nonagon,what is the value of x
Answer:
[tex]x=40^o[/tex]
Step-by-step explanation:
the picture of the question in the attached figure
step 1
Find the measure of the interior angle of a regular nonagon
The formula to calculate the measure of the interior angle in any polygon is given by
[tex]\frac{(n-2)180^o}{n}[/tex]
where
n is the number of sides
In this problem we have
n=9 sides
substitute
[tex]\frac{(9-2)180^o}{9}=140^o[/tex]
step 2
Find the value of x
Remember that
The sum of the interior angle and the exterior angle in any vertex of the polygon must be equal to 180 degrees
so
[tex]x+140^o=180^o[/tex]
solve for x
[tex]x=180^o-140^o=40^o[/tex]
find the value of x

Four consecutive integers add up to 378
Answer:
The numbers are 93, 94, 95 and 96
Step-by-step explanation:
Four consecutive integers add up to 378.
Let the first number be x
Second number will be x+1
Third number will be x+2
And the fourth number will be x+3
These four numbers add up to 378
Which means, we add them up
x + (x+1) + (x+2) + (x+3)=378
x+x+1+x+2+x+3= 378
Collect like terms
4x+6=378
4x= 378-6
4x=372
Divide both sides by 4
x=378/4
x=93
The first number is 93
The second number is x+1 = 93+1= 94
The third number is x+2= 93+2= 95
The fourth number is x+3= 93+3=96
Add up the four numbers
93+94+95+96 = 378

For the given triangle, x = 5.1 cm and y = 6.1 cm.
Step-by-step explanation:
Step 1:
In the given triangle, the angle is 50°. It is given that the opposite side has a length of y cm and the adjacent side has a length of y cm. The hypotenuse of the triangle measures 8 cm.
To determine the length of the opposite side of the triangle, we use the sin of the given angle.
To determine the length of the adjacent side of the triangle, we use the cos of the given angle.
[tex]sin \theta = \frac{oppositeside}{hypotenuse} , cos \theta = \frac{adjacentside}{hypotenuse}.[/tex]
Step 2:
In the given triangle,
The length of the opposite side = y cm,
The length of the adjacent side = x cm,
The length of the hypotenuse = 8 cm,
The angle of the triangle = 50°.
[tex]sin \theta = \frac{oppositeside}{hypotenuse} , sin 50 = \frac{y}{8}.[/tex]
[tex]y = 0.7660 (8) = 6.128.[/tex]
[tex]cos \theta = \frac{adjacentside}{hypotenuse} , cos 50 = \frac{x}{8}.[/tex]
[tex]x = 0.6427 (8) = 5.1416.[/tex]
So x = 5.1416 cm and y = 6.128 cm. Rounding these off to one decimal place, we get x = 5.1 cm and y = 6.1 cm.

what has to be added to the sum of 5/8 and 8/5 to get 3
Answer:
31/40 has to be added to the sum of 5/8 and 8/5 to get 3.
Step-by-step explanation:
Solve this equation: 5/8 + 8/5 + f = 3, where f is the number that has to be added to the sum of 5/8 and 8/5.
The LCD of 5/8 and 8/5 is 40; thus, 5/8 + 8/5 = 25/40 + 64/40 = 89/40.
Then 89/40 + f = 120/40 (where 120/40 is equivalent to 3).
Subtracting 89/40 from both sides yields the desired result:
f = (120 - 89)/40 = 31/40
31/40 has to be added to the sum of 5/8 and 8/5 to get 3.
Answer:
[tex]\frac{31}{40}[/tex]
Step-by-step explanation:
let the unknown be x
[tex]\frac{5}{8} + \frac{8}{5} + x =3[/tex]
[tex]\frac{25+64+40x}{40} = 3[/tex]
cross multiply
25 + 64 + 40x = 3 × 40
89 + 40x = 120
collect like terms
40x = 120 - 89
40x = 31
divide both sides by 40
x = [tex]\frac{31}{40}[/tex]
therefore, [tex]\frac{31}{40}[/tex] has to be added to the sum of 5/8 and 8/5 to get 3

in a certain clothing store,6 shirts and 3 ties cost $79.50 ,and 3 shirts and 2 ties cost $41. determine the cost of each shirt.
Answer:
Each shirt cost $12
Step-by-step explanation:
First, we have to interpret this question and turn each to an equation, letting shirts represent the letter s and ties represent the letter t.
6 shirts and 3 ties cost $79.50 would be interpreted to 6s+3t=79.5 ,and 3 shirts and 2 ties cost $41 would be interpreted to 3s+2t=41
Hence we have two equations, and we solve them simultaneously.
6s+3t=79.5 (Equation 1)
3s+2t=41 (Equation 2)
We can either use the substitution method or the elimination method but for the sake of this question, we use the Elimination method.
6s+3t=79.5 (Equation 1)
3s+2t=41 (Equation 2)
We multiply equation 1 by 2 and we multiply equation 2 by 3, I'm prefer to eliminate the
2(6s+3t=79.5)
12s+6t=159 Equation 3
3(3s+2t=41)
9s+6t=123 Equation 4
We subtract equation 4 from equation 3.
12s+6t=159
9s+6t=123
12s-9s=3s
6t-6t=0
159-123=36
We therefore have
3s=36
Divide both sides by 3
s=36/3
s=12

Answer: D. 30 year fixed, 10% down at a fixed rate of 5%
Step-by-step explanation:
The total cost of the house is $276,650.
He has in his savings $28,000
10% of $276,650 = $27,665. This will cover for the down payment.
His monthly income is $4,475 and he will like to spend 30% of it on his mortgage = $4,475* 30%= $1,342.50.
From the bal of mortgage =
$276,650 - $27,665 = $248,985
$248,985/ (30*12) = $691.625 $248,985* 5% /12= $1037.45
Total monthly repayment = $1037.45+ 691.63= $1729.08

Employees of a discount appliance store receive an additional 20% off of the lowest price on an item.
an employee purchases a dishwasher during a 15% off sale, how much will he pay if the dishwasher
originally cost $450?
A. $280.90
B. $287
C. $292.50
D. $306
E. $333.89
Answer:
D. $306.
Step-by-step explanation:
If the dishwasher originally cost $450, then after applying 15% off, its price will be 100% - 15% = 85% of the original price:
[tex]\dfrac{85\%}{100\%} *\$450[/tex]
[tex]0.85*\$450 = \$382.5[/tex]
Thus, during the 15% off sale, the dishwasher will cost $382.5.
Now, the employees of the discount appliance store receive an additional 20% off; therefore, the price of the dishwasher will be 100% - 20% = 80% of $382.5:
[tex]\dfrac{80\%}{100\%} *\$382.5[/tex]
[tex]0.8*\$382.5=\$306[/tex]
Therefore, the employee will purchase the dishwasher at a price of $306, which is choice D.
Final answer:
The employee will pay $306 for the dishwasher, which corresponds to answer choice D.
Explanation:
The subject of this question is Mathematics, and it pertains to the calculation of cumulative discounts on an item. The question is designed to test the student's understanding of how to apply successive percentage discounts to an original price.
Original price of the dishwasher: $450
15% off sale discount: 0.15 × $450 = $67.50
Price after sale discount: $450 - $67.50 = $382.50
Employees receive an additional 20% off the lowest price: 0.20 × $382.50 = $76.50
Price after employee discount: $382.50 - $76.50 = $306
Therefore, the employee will pay $306 for the dishwasher, which corresponds to answer choice D.
Jerome found another feather that made the difference between the longest and shortest feather 1 3/4 inches what could be the length of the new father explain
Answer:
By assuming that shortest feather has a length of 1/4 inches, the length of the longest feather is 2 inches.
Step-by-step explanation:
A mathematical translation of the statement of the problem is:
[tex]x - y = \frac{7}{4}[/tex]
Where x, y represent the lengths of the longest and shortest feathers, respectively. Let assume that length of the shortest feather is 1/4 inches. Then, the length of the longest feather is:
[tex]x = y + \frac{7}{4}[/tex]
[tex]x = 2[/tex]
By assuming that shortest feather has a length of 1/4 inches, the length of the longest feather is 2 inches.
The length of the new feather that made the difference between the longest and shortest feathers is 1 3/4 inches.
Explanation:The question is asking for the possible length of the new feather that made the difference between the longest and shortest feathers. We know that the difference between these feathers is 1 3/4 inches.
To find the length of the new feather, we need to consider the lengths of the longest and shortest feathers.
Let's say the length of the shortest feather is x inches. Then, the length of the longest feather would be x + 1 3/4 inches. So, the equation would be: (x + 1 3/4) - x = 1 3/4 inches.
Simplifying the equation, we get: 1 3/4 = 1 3/4 inches.
Therefore, the length of the new feather is 1 3/4 inches.

Triangle ABC was dilated and translated to form similar triangle A’B’C’.
What is the scale factor of the dilation?
A. 1/5
B. 2/5
C. 5/2
D. 5/1
The scale factor for the transformation of the pre-image ABC to A'B'C' shown in the figure is 5/2
How to estimate the scale factor of the dilation
From the question, we have the following parameters that can be used in our computation:
The transformation of the pre-image ABC to A'B'C'
By definition, the scale factor is simply the ratio of sides of two corresponding figures
So, the scale factor (S) would be:
S = A'B'C'/ABC
The actual measurements are given as
ABC = 2
A'B'C' = 5
Substitute the known values into the equation
S = 5/2
Hence, the estimated scale factor is 5/2

Hey there! Welcome to Brainly!
When solving equations for a variable, our goal is to get the variable all by itself on one side of the equation to show what it equals.
In your case, there are two variables, but there is no need to worry! Just pretend like C is another number; you are still solving for x.
So, how do we isolate the x? What we need to do is use inverse operations. If you were to say that x+1=20, how would you figure out what x is? Well, you have to get rid of the one next to the x. We need to subtract this one. But, if we subtract the one, we have to do it to the other side of the equation as well so that it balances it out. This leaves us with x=19.
Now, let's figure out your problem. You have a few more steps. When solving bigger equations, you first undo the constants (terms without a variable) and then the coefficients (numbers with variables attached).
So, the first thing we need to do is add 20 to both sides to cancel out the subtracting on x's side.
C+20=25x-20+20
C+20=25x
Now, we need to divide both sides by 25 to completely isolate the x.
(C+20)÷25=x
In algebra, it is customary to put the x on the left side of the equation, so we will just flip it around.
x=(C+20)÷25
We can further simplify this because the 20 in the numerator and 25 in the denominator are not in simplest form.
[tex]\frac{C+20}{25} =\frac{C+4}{5}[/tex]
Given this information, you should be able to put the steps in order accordingly.
I hope this helps! Have a great day!
