Answer:
That's all you're doing is writing the equation for two lines and finding out where they intersect. The slope is how much the price is increasing or decreasing and the y-intercept is where the price is starting at.
x = number of hours
y = mx + b = 0.12(x + 3) + 15.21 {It's (x + 3) because we have to add the 3 hours between 9 and noon}
y = mx + b = -0.11x + 15.96 {The slope is negative because the price is decreasing}
Set them equal to each other
0.12(x+3) + 15.21 = -0.11x + 15.96
Now solve for x
0.12x + 0.36 + 15.21 = -0.11x + 15.96
0.12x + 15.57 = -0.11x + 15.96
0.12x + 0.11x = 15.96 - 15.57
0.23x = 0.39
x = 0.38 / 0.23 = 1.7 hours
Convert 0.7 into minutes
0.7 hours * (60 min / 1 hour) = 42 min
So the prices are the same 1 hour and 42 min after noon, which is 1:42 PM

Answer:
Option B is correct.
Step-by-step explanation:
We need to find the value of S in cos S = 0.9092
cos S = 0.9092
To find value of S we will find cos^-1(0.9092) i.e
S = cos^-1 (0.9092)
S = 24.6 °
So, the measure of the angle to the nearest tenth of a degree of cos S = 0.9092 is 24.6°
So, Option B is correct.
Answer:
(7x9)x10 the power of 3 is 63,000
Answer:
B, because thats dividing, which equals 3. for the answer A, did you mean 15*5?
Step-by-step explanation:
Answer:
13.75 is your answer
Step-by-step explanation:
find area of whole triangle 5.5*7*1/2=19.25
Find area of blank spot 5.5*2*1/2=5.5
Subtract 19.25-5.5=13.75
