You would earn 153$, 102 divided by 12 is 8.5 so now you know how much you make an hour, now you work 18 hours so the equation would be : 8.5x18=153$

HELP ME DO THIS PLZ

Answer:

It landed at a height of 14 feet

Step-by-step explanation:

Given

y = -\frac{1}{8}x^2 +4x --- Path of a t-shirt

3y = 2x - 14 --- height of bleachers

Required

Height when t-shirts land in bleachers

3y = 2x - 14

Make y the subject

y = \frac{2}{3}x - \frac{14}{3}

Substitute y = \frac{2}{3}x - \frac{14}{3} in  y = -\frac{1}{8}x^2 +4x

\frac{2}{3}x - \frac{14}{3} =  -\frac{1}{8}x^2 +4x

Multiply through by 24

16x- 112 = -3x^2 +96x

Express as:

3x^2 + 16x  -96x- 112 = 0

3x^2 -80x- 112 = 0

Using a calculator:

x = 28 or x = -\frac{4}{3}

x can not be negative:

So:

x = 28

Substitute x = 28 in y = -\frac{1}{8}x^2 +4x to calculate the height it landed

y = -\frac{1}{8} * 28^2 + 4 * 28

y = 14

Define the formula for the surface area of a square pyramid.
 A square pyramid has a square base and four triangular sides.
 The formula for this case is:
 A = s ^ 2 + 2 * s * L
 Where,
 s: side of the base
 L: inclined height
 The inclined height is:
 L = root (h ^ 2 + (s / 2) ^ 2)
 Where,
 L = root (12 ^ 2 + (12/2) ^ 2)
 L = root (144 + 36)
 L = root (180)
 L = 13.42
 Substituting values:
 A = (12) ^ 2 + 2 * (12) * (13.42)
 A = 466.08 in ^ 2
 Answer:
 
The surface area is:
 
A = 466.08 in ^ 2
