E * 0.8 = 115
E = 115/.8 = $143.75
~~~~~~~~~~~~~~~~
B * 0.15 = 7
B = 7/.15
B = $46.67
The correct choice is C .
Answer:
45
Step-by-step explanation:
1 hour = 60 minutes
15 / 20 = x / 60
solve for x
15*3 / 20*3 = x / 60
45 / 60 = x / 60
denominators cancel
x = 45

Step-by-step explanation:
The cosine function crosses the midline at x = pi/2 = 1.57, so point (pi/2, 0) will be on the graph. It has a peak at x=0. The vertical scale factor of 4 mean the peak is (0, 4).
Your sine tool will be able to plot the graph using these two points.
__
If you need a maximum or minimum that is to the right of the midline point, you can use the minimum at (pi, -4) = (3.14, -4).
Answer:
45, 180, 145
Step-by-step explanation:
Let n represent the first number. Then "one number" is 4n, and the third number is n+100. The sum of the three numbers is ...
n + 4n + (n+100) = 370
6n = 270
n = 45
4n = 180
n+100 = 145
The three numbers are 45, 180, 145.
