Answer:

<u>The height of the scale model is 13.92 feet. (Rounding to the nearest hundredth).</u>

Step-by-step explanation:

These are the measurements of the real building:

Height = 30 feet

Width = 30 feet

Length = 30 feet

Volume of the real building = 30 * 30 * 30 = 27,000 cubic feet

These are the measurements of the scale model:

Volume of the scale model = 10% of 27,000 cubic feet

Volume of the scale model = 0.1 * 27,000 = 2,700 cubic feet

Height = ∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)

Width =  ∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)

Length =∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)

<u>The height of the scale model is 13.92 feet.</u>

If one mile is 1760 yards, to find 1/8 of a mile in terms of yards, we can divide 1760 by 8.

1760 yards / 8 = 220 yards

How do you write quotient 1,152 as an equation
timofeeve [1]
First we will divide. Lets do it:-

1152 ÷ 2 = 576.

Now we will check our work:-

576 × 2 = 1152.

So, the quotient 1152 as an equation is:- 1152 ÷ 2 = ?.

Help me on number 21 pls anyone I give brainlest
Ludmilka [50]

Answer:

The answer would be 34.07.

Step-by-step explanation:

I found this answer by using the pythagorean theorem, which is also known as a^2 + b^2 = c^2. So that means that x is equal to a, 35 is equal to b, and lastly 8 is equal to c. So the equation that you would have would be, x^2 + 35^2 = 8^2. Now to simplify it, you would get x^2 + 1225 = 64. Then you have to subtract 1225 on both sides which would get you x^2 = -1161. Then lastly you have to find the square root which would be 34.07 rounded to the nearest hundred.

Brainliest would be appreciated.

Have a nice day.
