Answer:
Step-by-step explanation:
other runner runs in 12 seconds=100 m
runs in 9.9 seconds=100/12 ×9.9=990/12=330/4=165/2=82.5 m
you beat him by 100-82.5=17.5 m
Answer:
the number of grams of zinc contain is 78
Step-by-step explanation:
The computation of the number of grams of zinc contain is shown below:
Given that the ratio of zinc to copper is 3:16
And, the jar of the chemical has 416 grams copper
So, the number of zinc grams would be
here we assume the zinc grams be x
Now the equation would be
3 ÷ 16 = x ÷ 416
Now applied the cross multiplication
16x = 416 × 3
x = (416 × 3) ÷ 16
= 78
Therefore the number of grams of zinc contain is 78
Well, a rectangle has 4 sides and the opposite side is at an equal length so you want to do 25 in. times 2= 50 inches. Then you want to subtract the 50 inched from 64 inches which will equal = 14. Then to get the other side lengths you need to divide it my two which is 7.
So your side lengths are seven inches. The word is side lengths.
It would be 12% of 50
50 * 12/100 = 600/100 = 6
so, 6 cars are red
I’m getting 61/24 I’m sorry if it’s wrong.
