The answer is 15. you add up all the numbers, and divide it by 5 because thats how many numbers there are. Pretty basic ;)

You just have to add all the number together and divide it by the amount of the number so it would equal 15

The mass of an adult North Pacific right whale is about 70,000 kg, or 7 x 104

olasank [31]

Answer:

Answer B: $1*10^2$ times

Step-by-step explanation:

To find how many times more massive is the whale relative o the polar bear, we just need to find the quotient of one over the other:

$\frac{7*10^4}{7*10^2} = \frac{7*10^2*10^2}{7*10^2}=1*10^2$ times

Therefore our answer agrees with the one shown as answer B.

dem82 [27]

9514 1404 393

Answer:

5 miles

Step-by-step explanation:

An hour and 25 minutes is 85 minutes. Using the given information we can find the distance d with the proportion ...

$\dfrac{\text{distance}}{\text{time}}=\dfrac{d}{85\text{ min}}=\dfrac{1\text{ mi}}{17\text{ min}}\\\\d=\dfrac{85\text{ min}}{17\text{ min}}(1\text{ mi)}\qquad\text{multiply by $85$ min}\\\\d=5(1\text{ mi})\qquad\text{simplify}\\\\d=\boxed{5\text{ mi}}$

In 1 hour and 25 minutes, Nick will travel 5 miles.

Solve for y 3y^2=432

Andreas93 [3]

Answer:Each Y could equal 12

Step-by-step explanation:

You would divide each side of the equation y 3 to get y^2=144.

Next take the root of both sides to get y= ± 12

After that just separate the solutions and get 12.

(I hope this helps. I tried)
