The ratio of boys to girls in a math class is 18 to 11. is that proportional to the science class with a ratio of 16 girls to 14 boys?

question 10 options:

154 ≠ 288

224 ≠ 198

176 ≠ 252

The ratio of boys to girls in a math class is not proportional to the ratio of boys to girls in a science class

154=288

Step-by-step explanation:

Let

x ----> the number of boys

y ----> the number of girls

we know that

The ratio of boys to girls is x/y

we have

Math class

Science class

equate both ratios

Multiply in cross

----> is not true

therefore

The ratio of boys to girls in a math class is not proportional to the ratio of boys to girls in a science class

  A- 12 percent

Step-by-step explanation:

You can see on the graph that the charged percentage of capacity changes from 40 to 50 in 5 minutes. Then the increase in 6 minutes will be slightly more than 10 percent.

The linear rate is (10%)/(5 min) = 2%/min, so in 6 minutes it will be

  (2%/min)×(6 min) = 12%

This calculation is consistent with our observation from the graph.

Every 6 minutes, 12 percent is added to the capacity.
