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.

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.

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.

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

Answer:

x⁻²

Step-by-step explanation:

[tex]\frac{x^6}{x^8} = \frac{1}{x^2} = x^-^2[/tex]

In the form of xⁿ , the expression is x⁻²

An expression is a mathematical statement which consist of variables , constants and mathematical operators.

The expression given is

[tex]\rm \dfrac{x^6}{x^8}[/tex]

By the exponent rule

[tex]\rm \dfrac{a^m}{a^n} = a^{m-n}[/tex]

so,

[tex]\rm x^{6-8}\\x^{-2}[/tex]

Therefore in the form of xⁿ , the expression is x⁻² .

Step-by-step explanation:

Hi there,

In order to solve this expression, you need to substitute x for 1.

You will end up with this expression:

3([tex]1^{2}[/tex]) - 2(1) + 1

Now, simplify the expression.

⇒ 3 - 2 + 1

⇒ 1 + 1

⇒ 2

Therefore, the answer when we evaluate the polynomial for x = 1 is 2.

Could you plz give me a crown I'm really close to leveling up!

The area of the rectangle that measures 16/5 inches by 10/4 inches is 8 inches².

A rectangle is a 2-dimensional quadrilateral with four right angles. A rectangle has two diagonals of equal length which bisect each other.

Area of a rectangle = length x width

16/5 x 10/4 = 160 / 20 = 8 inches²

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.
