It's a little hard to tell what is supposed to go in the middle column. The column on the right can be filled directly from the problem description: at 2 calendar years, the equivalent is 24 human years, and the number of human years increases by 4 for each increase of 1 calendar year.
The multiplier in the expression is obviously 4, as we are told the number of human years is 4 times the difference from 2 calendar years. (each year after 2 ...)
Well if you take the two numbers and divide them, 9/12 you get 3/4 i would probably say B. 3:4
Answer:
24

Answer
The steel ball will be caught up in between the mercury and water medium.
Step-by-step explanation:
- Mercury with a density of 13546 kg/m^3
- water with a density of 1000 kg/m^3
- Steel with a density of 8050 kg/m^3
From the factual density of both substances given above ,it shows that mercury is more heavier than water. In that case mercury will be at the lower layer when mixed with water.
The steel ball will be caught in between both mixtures as the density of steel is 8050 kg/m^3.Which is more than Water but less than Mercury.
Answer:
6/21.
Step-by-step explanation:
let the rational number be 2x/7x.
2x + 4 / 7x - 2 = 10 /19
Cross multiply:
19(2x + 4) = 10(7x - 2)
38x + 76 = 70x - 20
96 = 70x - 38x
32x = 96
x = 3.
So the rational number is 2*3/ 7*3
= 6/21.
