There would be a ratio of of 3/5 boys to girls. 3/5 of 200 is 120
I feel like that's irrelevant because those numbers don't add up.
Take 1 unit so 1/8 then factor it into 200.
you get 25
25*3 is 75.
75 is 37.5% of 200

The percentage of male students is 37.5%

- There for every five girls there are three boys.

- That is eight students per.

- I took two hundred and divided it by eight to get twenty-five.

- I got twenty five, if you take twenty-five times three you get seventy-five & if you take twenty-five times five you get one hundred twenty-five.

- Add those two products and you'll have your two hundred.

- So, take seventy-five over two hundred to get thirty-seven and a half.

- Divide that by one hundred to get the ratio.

- It comes out to 37.5%

The area of a window is 336 square inches if the window is 16 inches wide how long is the window
Ksenya-84 [330]
The formula for area is base times height, or height x width
So if the window is 16 inches wide then 336 divided by 16 equals the height
336 divided by 16 is 21.
Check
21 x 16 = 336
336 = 336

The pitch of the roof is given by the ratio of the rise to the run of the roof, which is the slope of the rafter

The \ pitch  \ of  \ the \  roof  \ is \ \mathbf {\dfrac{6}{13}}

Please find attached the simple <u>diagram of the house</u> with all measurements labeled

The reason the above value for the pitch and the diagram are correct are as follows:

The given parameters are;

Width of the section of the house on which the gable of the roof is to be placed = 50 feet

Length of the over hang on the sides of the roof = 1 foot each

Total span of the roof = 52 feet

Horizontal length of each rafter, the run = 26 feet

The height of the ridge above the top of the frame, the rise = 12 feet

Required:

  • To find the pitch of the roof
  • To draw a diagram of the house showing measurements

Solution:

Pitch = \dfrac{Rise}{Run}

  • Pitch  \ (slope) \ of \ roof =  \dfrac{12}{26} =\dfrac{6}{13}

Please find attached the <u>diagram</u> of the house showing the measurements for the roof parameters and the section of the house where the gable roof is to be placed
