Water flows at a rate of 6500 cubic inches per minute into a cylindrical tank. The tank has a diameter of 120 inches and a height of 72 inches. What is the height, in inches, of the water in the tank after 5 minutes? Round your answer to the nearest tenth.

Answers

Answer:

The answer is 1.2

Step-by-step explanation:

Hope this helps

The height of the water in the tank after 5 minutes is 2.87 inches if the tank has a diameter of 120 inches and a height of 72 inches.

What is a cylinder?

In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.

We know the volume of the cylinder is given by:

[tex]\rm V = \pi r^2 h[/tex]

We have:

Water flows at a rate of 6500 cubic inches per minute into a cylindrical tank.

Volume or amount of water after 5 minutes:

= 6500×5

= 32500 cubic inches

The base area of the cylindrical tank = πr²

r is the radius of the tank

The diameter of the tank = 120 inches

The radius r = 120/2 = 60 inches

The base area of the cylindrical tank = π(60)² = 79200/7

∵ π = 22/7

The height of the water in the tank after 5 minutes

= 32500/(79200/7)

h = 2.87 inches

Thus, the height of the water in the tank after 5 minutes is 2.87 inches if the tank has a diameter of 120 inches and a height of 72 inches.

Sam made a model of the Liberty Bell with a
base circumference of 8 inches. If the base
crcumference of the actual Liberty Bell is 12
feet, what scale did he use?

Answers

Answer:

1 : 18

Step-by-step explanation:

When finding scale factor, both measurements should in same unit

Circumference of the model bell = 8 inches

1 feet = 12 inches

12 feet = 12 * 12 = 144 inches

Circumference of the actual bell = 12feet = 144 inches

Model  : Actual = 8 : 144

                           = 8÷8 : 144÷8

                           = 1 :  18

Finn has $60 in a savings account. The interest rate is 10% per year and is not compounded. How much interest will he earn in 1 year?

Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.

Answers

Answer:

6$

Step-by-step explanation:

Answer:

I = $ 6.00

Step-by-step explanation:

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year,

then, solving our equation

I = 60 × 0.1 × 1 = 6

I = $ 6.00

The simple interest accumulated

on a principal of $ 60.00

at a rate of 10% per year

for 1 years is $ 6.00.

Step-by-step explanation:

brainliest please?

Answer:

336703275

Step-by-step explanation:

This is simple multiplication:

When you 'multiply' or 'times' a number you add it to itself a number of times, for example, 8475 multiplied by 39729 is the same as saying 8475 +8475 + 8475 = 336703275. Multiplication is therefore a quicker way of adding the same number many times, for example, 8475 x 39729 = 336703275.
