Kenny’s weight is 6/7 times Melvin’s weight.
Mazyrski [523]

Answer=7:13


Kenny's Weight*6/7=Melvin's Weight


So, for example, if Melvin's weigh was 7...


Kenny's Weight*6/7=7

divide both sides by 6/7

Kenny Weight=6


So we can say that Melvin's weight to Kenny's weight is 7:6


The boys total weights would be...

7+6=13



So Melvin's weight over the total weight of the two boys is:


7:13

I need to know how to find the mass and how to get the answer by showing the work.
BigorU [14]
1 ft = 12 in
6 in = 6/12 = 0.5 ft
9 in = 9/12 = 0.75 ft

D = M/V  ⇒  M = DV

V = 0.5 * 0.5 * 0.75 = 0.1875 cubic foot
M = 41.7 * 0.1875 ≈ 7.8 pounds

Answer: B.

Sara got 88, 90, 75, 78, 100, 54, 90, 100, 45, and 60 on her English tests
Dmitrij [34]
The answer is 78 because when you add all the numbers it equals 780 and you need to divide the end sum by the amount of numbers added to get it. So in the end there were 10 numbers added to equal 780 so 780\10 equals 78
