Answer:
10 %
Step-by-step explanation:
let the percent be x
according to the question
7.8 = x % 0f 78
7.8 = x /100 * 78
7.8*100 = 78x
780 = 78x
780/78 = x
10 = x
Answer:
x = 11m
Step-by-step explanation:
The longest side is the bottom (15m). If you look at the sides you can see that the side that measures 4m is parallel with the side that measures 15m. Anytime two sides overlap to make x, we can simplify by subtracting or adding. All we need to do is subtract to find the length of x.
15 - 4 = 11m
I’m really really sorry i can’t ask another question until i answer somebody’s questions.

Answer:
106
Step-by-step explanation:
The diameter of the wheel is 15 cm or 0.15 m.
The circumference of the wheel is 0.15π m ≈ 0.47 m.
So the wheel moves 0.47 m with each revolution.
The wheel travels 50 m, so the number of revolutions is:
(50 m) / (0.47 m/rev) ≈ 106 revolutions.
