Answer:
$42.50
Explanation:
If you divide 34 by 4 you get 8.5. Then you just add 8.5 to 34 to get 42.50.
Answer:
E
Step-by-step explanation:
57 - 36 = 21 6 - 4 = 2 seconds
21 ÷ 2 = 10.5
By solving a system of equations, we will see that m measures 12 units.
<h3>
How to get the measure of m?</h3>
Notice that we have 3 right triangles.
Then we can write the equations:
cos(a) = 6/m
For the small triangle on the left, where m is the hypotenuse.
cos(a) = m/(6 + 18)
For the larger triangle (the one composed of the two triangles).
Where in both equations, angle "a" is the one in the top left.
Then we have the system of equations:
cos(a) = 6/m
cos(a) = m/(6 + 18)
Then we can write:
6/m = m/(6 + 18)
If we simplify the expression, we get:
6*(6 + 18) = m^2
6*(24) = m^2
144 = m^2
√144 = m = 12
Then we conclude that m measures 12 units.

Answer:
4.63
Step-by-step explanation:
4/5 of an hour is 48 minutes
1 4/5 hour is 60 + 48
which is
108 minutes
he ran 8 1/3 miles in 108 minutes
so
(8 1/3 times 60 ) ÷ 108
which =
4.6296296296 miles in one hour
