The ratio of jumps to falls for ice skater Rhonda is 4 falls to every 15 jumps. At this rate, how many times will she not fall i
Inessa05 [86]

<u>Answer:</u>

Rhonda will not fall 264 times in 360 jumps.

<u>Solution:</u>

Given, The ratio of jumps to falls for ice skater Rhonda is 4 falls to every 15 jumps.  

We have to find At this rate, how many times will she not fall in 360 jumps.

Now,  

For 15 jumps → 4 falls

For 360 jumps → n falls

Now apply Chris cross method,

15 \times n=360 \times 4 \rightarrow n=\frac{360 \times 4}{15}=24 \times 4=96

So, she falls 96 times in 360 jumps.

Then, number of times she will not fall = 360 jumps – 96 falls = 264 times.

Hence, Rhonda will not fall 264 times in 360 jumps.

Using scientific notation, the correct statement is given by:

C. Corporation C owns the most land. Corporation A owns 8 times more land than corporation B.

<h3>What is scientific notation?</h3>

A number in scientific notation is given by:

a \times 10^b

With the base being a \in [1, 10).

Considering the amounts in scientific notation, the standard amounts in acres of each corporation are given as follows:

  • Corporation A: 3.2 \times 10^5 = 320000 = 320,000.
  • Corporation B: 4 \times 10^4 = 40000 = 40,000.
  • Corporation C: 4.3 \times 10^5 = 430000 = 430,000.

Hence corporation C owns the most land. 320,000/40,000 = 8, hence Corporation A owns 8 times more land than corporation B, and statement C is correct.

Novosadov [1.4K]

if we take 30 to be the 100%, what is 27 off of it in percentage?

\begin{array}{ccll} amount&\%\\ \cline{1-2} 30 & 100\\ 27& x \end{array} \implies \cfrac{30}{27}=\cfrac{100}{x} \\\\\\ \cfrac{10}{9}=\cfrac{100}{x}\implies 10x=900\implies x=\cfrac{900}{10}\implies x=90
