Mathematics

Aliun [14]3 years ago
5 0

Answer:

Average rate of increase will be 0.0466 feet/year

Step-by-step explanation:

We have given that the scientific studies indicate that the ocean level could rise 3.5 feet in 75 years

So rise in level of ocean = 3 feet

Time by which the ocean level rise = 75 years

We have to find the average rate of ocean rise

Average rate of ocean rise is given by \frac{rise\ in\ level}{total\ time}=\frac{3.5}{75}=0.0466feet/year

If 8 cakes cost $62.40, how much would 3 cakes cost?
Ilya [14]

Answer:

<h2><em><u>$23.40 </u></em></h2>

Step-by-step explanation:

<em><u>Given,</u></em>

Cost price of 8 cakes = $62.40

<em><u>So,</u></em>

Cost price of 1 cake = $ \frac{62.40}{8}

= $(7.80 × 3)

  • <em>[On multiplying]</em>

= $23.40

<em><u>Hence,</u></em>

<em><u>The required cost of 3 cakes is $23.40 (Ans)</u></em>
