Answer:
B The number of candles Sallie sells
Step-by-step explanation:
Given the equation :
y = 8x
y = amount earned ; x = number of candles sold
Cost per candle = 8
The Independent variable is the number of candles sallie sells as it is this variable which determines the amount which sallie will earn from candle sales (dependent variable). In essence, the variable which determines or affects the dependent variable is the independent variable.
Tan(Ф) = 4/3
tan(Ф) = b/6Ф, then 4/3 =b/6
cross multiplication: 3b=24 and b= 24/3, b = 8 (answer D)
The distance from his home to his work place is 118.125 miles
<h3>How to find the distance from his home to his work place?</h3>
He drove from home to work at an average speed of 45 mph. Therefore,
speed = 45 mph
let
time = x
speed = distance / time
distance = 45x
His return trip home took 45 minutes longer because he could only drive at 35 mph. Therefore,
45 minutes = 0.75 hours
distance = 35(x + 0.75)
distance = 35x + 26.25
Therefore,
45x = 35x + 26.25
45x - 35x = 26.25
10x = 26.25
x = 26.25 / 10
x = 2.625
Therefore,
distance = 45(2.625) = 118.125 miles
