Answer:
Hours are equal: 7.2
Cost of service are equal: 51.4
Step-by-step explanation:
<u>Happy Paws:</u>
y = 4.5h + 19
<u>Woof Watchers:</u>
y = 5.75h + 10
<u>To solve for the hours are equal:</u>
y = 4.5h + 19
y = 5.75h + 10 (Multiply by -1)
y = 4.5h + 19
-y = -5.75h - 10
0 = -1.25h + 9
-9 = -1.25h
h = 7.2
<u>To solve for when the services are equal:</u>
y = 4.5h + 19
y = 4.5(7.2) + 19
y = 32.4 + 19
y = 51.4
Answer:
<em>Expected Payoff ⇒ $ 1.50 ; Type in 1.50</em>
Step-by-step explanation:
Considering that 1 out of the 100 tickets will have a probability of winning a 150 dollar prize, take a proportionality into account;
<em>Thus, Solution ; Expected Payoff ⇒ $ 1.50</em>
A south pole of one magnet can approach the north pole of another. The magnetic fields are aligned. This makes an attractive force between the two magnets. The farther apart they are, the higher their potential energy.

Answer:
20 hours
Step-by-step explanation:
use this linear equation
y = 9.25x + 50
plug in 235 for y and solve for x
235 = 9.25x + 50
185 = 9.25x
20 = x
so he worked for 20 hours
hope this helped <3
