Advocard [28]

Answer:

D. 22 Cars and 8 Vans

Step-by-step explanation:

1. You multiply 22 x 150 = 3,300.

2. Then you multiply 300 x 8 = 2,400.

Find the percent of change: 100 acres to 140 acres
nydimaria [60]

Answer: 40%

Step-by-step explanation: First determine whether the number increases or decreases. Since the number changes from 100 to 140 it's getting bigger, so it increases.

To find the percent increase, we use the following formula.

The amount of change is the difference between the two numbers which is 40 and we get this by subtracting 100 from 140. The original number will be the number that we started with which is 100.

140/100 simplifies to 0<em>.</em>4.

Finally, we want the percent increase so we write 0<em>.</em>4 as a percent by moving the decimal point 2 places to the right to get 40%.

Therefore, the percent increase is 40%.

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

two-fifth of the fish in Gary's fish tank are guppies. One-fourth of the guppies are red. What fraction of the fish in Gary's ta
Gennadij [26K]

Answer:

1/10

Step-by-step explanation:

To find the number of red guppies, multiply the fractions.

Gary has 2/5 of his fish collection as guppies. Of the guppies, 1.4 are red.

So 2/5 * 1/4 = 2/20 = 1/10.
