1.) An elephant's heart beats 75 times in 3 minutes. It will beat 325 times in how many minutes?
I

13 minutes

Step-by-step explanation: common sence every minute the heart beats 25 times so 25 times 3 equals 75 so if that s true then 25 times 13 equals 325 ;)

Step-by-step explanation:

It is 12.99 - 13 min. because 325 divided by 75

equals 4.33 and so on. If you times 4.33 by 3

you get 12.99, if your teacher said to round it

then do 13 Min. Hope this helps! <3

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
