At a pet store customers can pay 12.50 for a fish tank and $.20 for each fish. what is the rate of change in the situation described?

At a pet store a customer can buy up to 63 fishes , with $0.20 per fish as he have $12.50 . With every $0.20 , customer can buy 1 fish i.e. rate is $0.20 per fish !

Step-by-step explanation:

Here we have , At a pet store customers can pay 12.50 for a fish tank and $.20 for each fish. We need to find what is the rate of change in the situation described . Let's find out:

It's given that each fish cost $0.20  , and a customer pays 12.50 . So , the number of fishes is bought is :

⇒

⇒

⇒

Rounding off ,

⇒

Therefore, At a pet store a customer can buy up to 63 fishes , with $0.20 per fish as he have $12.50 . With every $0.20 , customer can buy 1 fish i.e. rate is $0.20 per fish !

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
