Answer:

14080 ft

Step-by-step explanation:

You want to convert 4 mph to ft/min and then mult. the result by 40 minutes:

4 mph 5280 ft 1 hr

---------- * --------------- * ------------- = 352 ft/min

1 1 mile 60 min

Now multiply this rate (speed) by 40 minutes:

352 ft 40 min

---------- * ------------ = 14080 ft (answer)

min 1

This would be the same as 2 2/3 miles (in 40 min)

Harold uses a cone shaped feeder, with a diameter of 7.5 centimeters and a height of 3.5 centimeters, to feed his tropical fish.

Ilia_Sergeevich [38]

To find the volume of a cone you use the formula "1/3 x 3.14 x r^2 x h". Plug the formula into the problem. 1/3 x 3.14 x 3.75^2 x 3.5 =51.51. Rounded to the nearest tenth is 51.5. Hope this helps!

Three fourths a number plus 8 is 20 less than the number

VARVARA [1.3K]

Answer:

Equation: $\frac{3}{4}n+8=n-20$

Solve for n: n = 112

Step-by-step explanation:

To first set up the equation, you need to look at the verbal description and translate into numbers and operations:

'three fourths a number' = $\frac{3}{4} n$

'plus 8' = + 8

'is' =

'20 less' = - 20

'the number' = n

Put the expressions together:

'three fourths a number plus 8': $\frac{3}{4}n+8$

'20 less than the number': n - 20

Set them equal to each other and solve: $\frac{3}{4}n+8=n-20$

Add 20 to both sides: $\frac{3}{4}n+8+20=n-20+20$

Subtract $\frac{3}{4}n$ from both sides: $\frac{3}{4}n-\frac{3}{4}n+28=n-\frac{3}{4}n$

Multiply both sides by $\frac{4}{1}$ : $\frac{4}{1}28=\frac{1}{4}n\frac{4}{1}$

Solve for n: n = 112

A company that manufactures storage bins for grains made a drawing of a silo. The silo has a conical base, as shown below:

sasho [114]

To find the volume of this storage bin, you will use the formula for volume of a cylinder and of a cone.

V = Bh (cylinder)
Pi x r^2 x h
Pi x 2^2 x 10

V = 1/3 x pi x r^2 x h
1/3 x pi x 2^2 x 3

All of these choices show correct answers!
