Answer:
$15 per hour
Step-by-step explanation:
30 hours per week x 52 weeks in a year = 1560 hours per year
23,400 / 1560 = $15 per hour
Eq. 1 .10x + .25y = 9.45
Eq. 2 x + y = 60 rewrite as x = 60 - y and substitute into equation 1.
.10(60 - y) + .25y = 9.45
6 - .1y + .25y = 9.45
6 + .15y = 9.45
.15y = 3.45
y = 23
60 - 23 = 37
23 quarters
37 dimes
23* .25 = 5.75
37 * .1 = 3.70
5.75 + 3.70 =9.45
<h3>The surface area of cube is 162.24 square inches</h3>
<em><u>Solution:</u></em>
<em><u>The surface area of cube is given as:</u></em>

Where,
"s" is the length of each side of cube
From given,
s = 5.2 inches
Therefore,

Thus the surface area of cube is 162.24 square inches
PH = -log[H+]
= -log(2*10^-9)
= -(log(2) +log(10^-9))
= -(0.3 -9)
= 8.7
The appropriate choice is
C. 8.7
Answer:
The correct equation form for finding the price of a sandwich is 5x + 1.25 = 38.75 and the cost of each sandwich was $ 7.50
Step-by-step explanation:
1. Let's check all the information given for solving this question:
Cost of bag of chips = $ 1.25
Cost of sandwich = x
Cost of total order = $ 38.75
2. The formula for find the cost of sandwich (x) is this:
5x + 1.25 = 38.75 (Joaquin ordered 5 sandwiches and a bag of chips)
5x = 37.50 (Subtracting 1.25 at both sides)
5x/5 = 37.50/5 (Dividing by 5 at both sides)
x = 7.50
The cost of each sandwich was $ 7.50
