The mass of an adult north pacific right whale is about 70,000 kg, or 7 x 104
kg.
the mass of a male polar bear is about 700 kg, or 7 x 102 kg.
about how many times more massive is the right whale than the polar bear?
o a. 1x 10-2 times
o b. 1x 102 times
o c. 69300 times
od: : 12 times

Answer B: 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:

times

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

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
