Hey there!
Write a proportion. 8/5=32/x. Cross multiply. You get 8x=160. You have to isolate x, so divide each side by 8. X=20. Since x is by itself, you have your answer. The answer is B. Another way to do this is to see how much it takes to get from 8 to 32. You would multiply by 4. So multiply 5 by 4 to get 20.
I hope this helps!
Answer:
1/168
Step-by-step explanation:
First, solve for the numerator.
-5/7÷30
-5/7÷30/1
(use keep, change flip)
-5/7x1/30=-5/210
-5/210=-1/42
Now use keep change flip again
-1/42÷-4/1
-1/42*-1/4=1/168
Answer:
Science students
Step-by-step explanation:
MATHEMATICS :
Plot interval = 30 to 50
MEAN :
(34*2) + (40*2) + (32*1) + (33*1) + (35*1) + (37*1) + (39*1) = 324
Sample size, n = (2 + 2 + 1 + 1 + 1 + 1 + 1) = 9
Mean = 324 / 9 = 36
BOTTOM :
SCIENCE :
MEAN : (43*2)+(46*2)+(49*2)+(41*1)+(42*1)+(47*1) =
406
SAMPLE SIZE = (2 + 2 + 2 + 1 +1 +1) = 9
406 / 9 = 45.111
Answer:
0.395 kilometers
Step-by-step explanation:
Please consider the complete question.
On Martin's first stroke, his golf ball traveled 4/5 of the distance to the hole. On his second stroke, the ball went into the hole. Martin was standing 79 meters from the hole as he took his second stroke. How many kilometers from the hole was Martin when he started?
Let x represent the distance between hole and start point.
In 1st stroke ball traveled 4/5 of the distance, so 1/5 of the distance was remaining from 2nd stroke to hole. This means the 1/5 of whole distance between start point and hole is equal to 79 meters.
We can represent this information in an equation as:



Since our distance is in meters, so we will convert 395 meters into kilometers by dividing by 1000.

Therefore, Martin was 0.395 kilometers from the hole, when he started.
