Answer: $21.42

Step-by-step explanation:

First we must REDUCE the price by 15%.

But what is 15% of $24.00?

Well:

24 × .15 = 3.6

15% off of $24.00 means $3.60 off of $24.00

$24.00 - $3.60 = $20.40

The book is $20.40 on sale.

Next we must ADD 5% sales tax.

But what is 5% of $20.40?

Well:

20.4 × .05 = 1.02

$1.02 is 5% of $20.40

$20.40 + $1.02 = $21.42

The equation A = x(x - 7) describes the area, A, of a rectangular flower garden, where x is the width in feet.
mamaluj [8]

x(x-7)=8

x^2-7x-8=0

(x-8)(x+1)=0

so x=8 (and -1 but width can’t be negative)

So your answer is C. 8

Definitions given.
Yuki888 [10]

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
