The one who walked 1.2 miles would have made $72 and the one who walked 0.8 miles would have made $48.
Since it is under 985,000, you would round it down. So your answer rounded to the nearest ten thousand would be 980,000
Answer: 45
Step-by-step explanation:
The total degrees in a circle is 360.
The perpendicular angle that you see is 90 degrees, added to angles of x and 3x, you get the total degrees.
so 90 + x + 3x = 90 + 4x = total
90 + 4x = 360
4x = 180
x = 45 degrees
For this case, the first thing we must do is define variables:
x = number of quarters
y = number of dimes
We now write the system of equations:
x + y = 28
0.25x + 0.10y = 4.05
Solving the system of equations we have:
x = 8.33
y = 19.66
Rounding:
x = 8
y = 20
Answer:
the college student has:
8 quarters
20 dimes
