If l =12 cm and m =5 cm what is the length of n
a square root of 119 cm
b 10 cm
c 13 cm
d 14 cm

You have to use the Pythagorean Theorem. Follow what I do, and if you have any questions be sure to tell me. a^2+b^2=c^2 This is the formula. But don't get worried by the variables, you can always switch a and b for l and m. Also c can be switched for n. So not to get this confusing, I will substitute the letterings for you, l^2+m^2=n^2 Lets now substitute the variables with the numbers. 12^2+5^2=c^2 169=c^2 Remember that n equals to the square root of 169. n= √169 n=13

The humpback whales are 37 times bigger than the krills they eat

Step-by-step explanation:

In this question, we are interested in knowing how much bigger are humpback whales compared to krill.

what is simply happening here is to divide the weight of the humpback whales by the weight of the krills.

From the question, weight of humpback whales = 8 * 10^4 while the weight of the krills are 2.1875 * 10^3

So the number of times the humpback whales are bigger is;

(8 * 10^4)/(2.1875 * 10^3) = 36.57 which are approximately 37 times bigger
