Help!!!!!!!!!!!!!!!!!!!!!!!!!

torisob [31]

Answer:

53

Step-by-step explanation:

$\frac{sin(56)}{78.6} = \frac{sin(90)}{ab} \\ \\ absin(56) = sin(90) \times 78.6 \\ \\ ab = \frac{sin(90) \times 78.6}{sin(56)} \\ ab = 94.8 \\ \\ {x}^{2} + {78.6}^{2} = {94.8}^{2} \\ {x}^{2} = {94.8}^{2} - {78.6}^{2} \\ {x}^{2} = 8987.04 - 6177.96 \\ {x}^{2} = 2809.08 \\ x = \sqrt{2809.08} \\ x = 53$

The largest possible complete design that can be painted on a 24’ x 16’ wall is 252' by 189'

<h3>Scale drawing</h3>

Scale drawing involves drawing a drawing in a different size and dimension that is proportional to the original dimension

<h3>Dimensions</h3>

The dimensions of the design for the farm scene painting is given as:

$12" \times 9"$

The dimensions of the wall is given as:

$24' \times 16'$

Convert feet to inches

$24' \times 16' = (24 \times 12") \times (16 \times 12")$

$24' \times 16' = (288") \times (192")$

Divide the dimensions of the wall by the painting to get the scale ratios (k)

$k = \frac{288}{12}$

$k = 24$

Also, we have:

$k =\frac{192}{9}$

$k =21.33$

Remove decimal (do not approximate)

$k =21$

By comparison;

21 is less than 24

Multiply 21 by the dimensions of the painting

So, we have:

$Length = 12 \times 21 = 252$

$Width = 9 \times 21 = 189$

Hence, the largest possible complete design that can be painted on a 24’ x 16’ wall is 252' by 189'

The amount Max earned last week can be modeled by the expression 25 plus 5 i greater or equal than 95 comma where i is the numbe

Sunny_sXe [5.5K]

Answer:

Line 3 (or C)

Step-by-step explanation:

<u>The inequality as per description is:</u>

25 + 5i ≥ 95
5i ≥ 95 - 25
5i ≥ 70
i ≥ 70/5
i ≥ 14
i = [14, + ∞)

This is shown on the number line 3 on the picture or option C
