A movie theater uses a cone-shaped container to serve popcorn. The cone has a height of 12 inches and a volume of 16 π in2. What is the radius of the cone?
Volume can be defined as the capacity of a given container or a certain object.
The radius of the cone is 2 inches.
From the question, we are given the following parameters:
The height of the cone = 12 inches
The volume of the cone = 16 π in³
The formula to find the radius of the cone is given as:
√3V/πh
= √ 3 x 16π / π x 12
= 2 inches
Therefore, the radius of the cone is 2 inches.

A group of engineers developed a new design for a steel cable. They need to estimate the amount of weight the cable can hold. The weight limit will be reported on cable packaging. The engineers take a random sample of 44 cables and apply weights to each of them until they break. The 44 cables have a mean breaking weight of 778.1 lb. The standard deviation of the breaking weight for the sample is 15.5 lb.
Find the 99% confidence interval to estimate the mean breaking weight for this type cable.

Answer:
77/180
Step-by-step explanation:
x = 0.42777....
Multiply by 1000 (the number of digits in decimal)
1000x = 427.7777......
100x = 42.7777...... {Now subtract}
900x = 385
x = 385/900
x = 77/180

What is the slope of the line on the graph?
Enter your answer in the box.
Please help me!
Answer:
6
Step-by-step explanation:
We can use the points on the line to find the slope
(0,-1) and (1,5)
Using the slope formula
m = ( y2-y1)/(x2-x1)
= (5 - -1)/(1-0)
= (5+1)/(1-0)
= 6/1
= 6
Answer:
m = 6 units
Step-by-step explanation:
To get from point (0, -1) to point (1, 5) that are on the line we have to go up 6 units and 1 unit to the right
slope = rise /run = 6/ 1 = 6
The perimeter of a rectangular field is 358 m.
If the length of the field is 96 m, what is its width?
Answer: 83 meters
Step-by-step explanation:
The perimeter of a rectangle is 2l + 2w, where l is the length and w is the width.
2(96) + 2w = 358
192 + 2w = 358
2w = 166
w = 83

Which of the following is the measure of side a?
23.3
144
8
16
Step-by-step explanation:
it is a right-angled triangle, so the side lengths need to fulfill the Pythagoras rule :
c² = a² + b²
where c is the Hypotenuse, the baseline opposite of the 90 degree angle. and a and b (often called legs) are the sides "enclosing" the 90 degree angle.
so, we have
20² = a² + 12²
400 = a² + 144
a² = 256
a = 16
FYI - we could have picked the right answer also by eliminating the wrong given answer options.
as this is a right-angled triangle :
a cannot be longer than the baseline (20).
that eliminates already the first 2 options.
and then look at the picture : a cannot be shorter than b (the other side line (12)).
that eliminates the third option.

I need help with these 2 problems I cant figure out.
I started by labeling the right angle (Angle C) 90º. Next, I wrote down everything in one equation.
2x + 90 + 3x - 20 = 180º (180 degrees in a triangle)
Next, I add 20 on both sides.
2x + 90 + 3x = 200º
I combine like terms (2x and 3x)
5x + 90 = 200º
I subtract 90 from both sides.
5x = 110º
Divide 110 by 5 to get x.
x = 22
======
For problem two, I label all the angles I know.
49º + 80º + r = 180º
I add 80 and 49.
129º + r = 180º
I subtract 180 and 129 and get 51º, which is your angle for R.
For angle X, you know that angle R plus angle X equals half of a circle, which is 180º
We know from before that 129º is 180º without R, so X is 129º
I hope this helps! Let me know if I'm wrong!

Find the gradient and intercept on the x and y axes of the straight line with the following equation.
y + 5x = 13
Answer:
gradient is 5
Step-by-step explanation:
x intercept, replace y with 0
y +5x= 13
0+ 5x =13
0 - 13= -5x
-13= -5x
-13/-5 = -5x/-5
x = 13/5
y intercept, replace x with 0
y+5x=13
y+5(0)=13
y+0=13
y =13

An auto shop charges a customer an equal amount for each new tire purchased plus an additional fee for an oil change.
The function C(t) = 87t +32 represents the total cost, C, of getting an oil change and purchasing t, tires.
What does the number 87 represent in the function?
A The slope and the cost per tire purchased.
B The slope and the fee for an oil change.
The y-intercept and the cost per tire purchased.
The y-intercept and the fee for an oil change.
The cost per unit of the auto shop function is the slope of the function
87 represents the slope and the cost per tire purchased
The function is given as:
[tex]\mathbf{C(t) = 87t + 32}[/tex]
A linear function is represented as:
[tex]\mathbf{C(t) = mt + b}[/tex]
Where:
m represents the slope or the unit rate.
So, by comparison:
[tex]\mathbf{m = 87}[/tex]
This means that 87 represents the slope and the cost per tire purchased
