dimulka [17.4K]
<h2>Answer:</h2><h2>The actual height of the building = 36 feet.</h2>

Step-by-step explanation:

By blue print conversion,

2 inches = 8 feet

Therefore, 1 inch = \frac{8}{2} = 4 feet

1 inch = 4 feet

The height of the building on the  blueprint = 9 inches

The actual height of the building = 9 * 4 = 36 feet.

Kelly spends 5 hours each week playing softball and 4 hours each week practicing her violin. Write the ratio of hours spent prac
Pavel [41]

Given:

Kelly spends 5 hours each week playing softball and 4 hours each week practicing her violin.

To find:

The ratio of hours spent practicing violin to hours spent playing softball three different ways.

Solution:

We have,

Time spend on Softball = 5 hours

Time spend on Violin = 4 hours

The ratio to hours spent practicing violin to hours spent playing softball is

\text{Required ratio}=\dfrac{\text{Time spend on Violin}}{\text{Time spend on Softball}}

\text{Required ratio}=\dfrac{4}{5}

It can be written as

\text{Required ratio}=4:5

\text{Required ratio}=4\text{ to }5

Therefore, the ratio of hours spent practicing violin to hours spent playing softball three different ways are \dfrac{4}{5}, 4:5 and 4 to 5.

HELP PLEASE! Robert needs to cut four shelves from a board that is 2.5 meters long. The second shelf is 18 centimeters longer th
IRISSAK [1]
Let us assume the length of the first shelf = x
Then
The length of the second shelf = 2x + 18
Length of the third shelf = x -12
Length of the fourth shelf = x + 4
The total length of the board = 2.5 meters.
                                              = ( 2.5 * 100) cm
                                               = 250 cm
Then we can write the equation as
x + 2x + 18 + x - 12 + x + 4 = 250
5x + 10 = 250
After dividing both sides of the equation by 5 we get
x + 2 = 50
x = 50 - 2
   = 48
Then
The length of the second shelf = 2x + 18
                                                 = 2(48) + 18
                                                 = 96 + 18
                                                 = 116
So the length of the second shelf is 116 cm.
