ehidna [41]
Answer:

I believe it is, 30 minutes of running.

Explanation:

If she spends 12 minutes walking, that means she’s done 6 ‘sets’ of two minutes.

at the zoom,the ratio of monkeys to gorrillas is 5:2 if there were 20 monkeys how many gorrilas would there be?
Umnica [9.8K]

8 gorrilas

Explanation:

The ratio of monkeys to gorrila = 5:2

This means there are 5 monkeys for every 2 gorrilas

when there are 20 monkeys,

let the number of gorrilas = x

5 monkeys = 2 gorrilas

20 monkeys = x

cross multiply:

5(x) = 20(2)

5x = 40

divide both sides by 5:

5x/5 = 40/5

x = 8

Hence, if there were 20 monkeys, we would have 8 gorrilas.

The average rate of change of g(x) between x = 4 and x = 7 is 5/6 . Which statement must be true?
Blizzard [7]

Answer:

\frac{5}{6}=\:\frac{g\left(7\right)-g\left(4\right)}{7-4}  would be the correct statement.

Step-by-step explanation:

As we know that

Average rate of change = Change in output / Change in input    

                                        =  Δy  / Δx

                                        =\frac{y_{2} -y_{1}}{x_{2} -x_{1}}

                                        =\frac{g(x_{2})-g(x_{1})}{x_{2}-x_{1}}

                                         =\frac{g(7)-g(4)}{7-4}                    

As the average rate of change of g(x) between x = 4 and x = 7 is 5/6.

so

\:Average\:rate\:of\:change\:=\:\frac{g\left(7\right)-g\left(4\right)}{7-4}

                                  \frac{5}{6}=\:\frac{g\left(7\right)-g\left(4\right)}{7-4}

Therefore, \frac{5}{6}=\:\frac{g\left(7\right)-g\left(4\right)}{7-4}  would be the correct statement.

How to put 50,000,000 in standard form?
SVEN [57.7K]

Answer:

50,000,000 is in standard form.

Step-by-step explanation:

This is because standard form would be a written number. So, the non-standard form of 50,000,000 would be fifty million.
