25-9=16 grams - weight of copper
(16/25)*100=64 percents
Answer:
A) c = 16.5h
B) $74.25
C) 7 hours
Step-by-step explanation:
Bazinga charges $16.50 per hour to dog sit.
Therefore, to calculate the total charge, multiply the number of hours by the charge per hour:

<h3><u>Part A</u></h3>
As explained above, to calculate the total charge, multiply the number of hours worked by the charge per hour of $16.50
⇒ c = 16.5h
where:
- h = number of hours worked
- c = total charge (in dollars)
<h3><u>Part B</u></h3>
To calculate how much Bazinga will earn if they dog sit for 4.5 hours, substitute h = 4.5 into the equation and solve for c:
⇒ c = 16.5h
⇒ c = 16.5(4.5)
⇒ c = $74.25
<h3><u>Part C</u></h3>
To calculate how long it will take Bazinga to earn $115.50, substitute c = 115.5 into the equation and solve for h:
⇒ c = 16.5h
⇒ 115.5 = 16.5h
⇒ h = 115.5 ÷ 16.5
⇒ h = 7 hours
The answer is to that question is 85°
Answer:
Step-by-step explanation:
y = (-1/m)x + c
the slope here is -1/m
a perpendicular line will have a negative reciprocal slope...all that means is flip the slope and change the sign.
-1/m....flip the slope....-m/1......change the sign....m/1 which is the same as m
I cant tell u the equation of the line perpendicular, but I can tell u that is has a slope of m.
