rosijanka [135]

Answer:

As we can see the average for the thickness of a chickens egg shell is 0.311 mm and if we want to round this number to the nearest tenth we just need to see the second decimal place and round to one decimal place.

This second decimal place for this number is 1 and this number is $\leq 5$ so then if we round to the nesrest tenth we will get:

$0.3 mm$

Step-by-step explanation:

We use the following info in order to complete the qeustion:

If you borrow $675 for six years at a interest rate of 10% how much interest will you pay

murzikaleks [220]

Answer:

the answer is $40.5

Step-by-step explanation:

the basic formula of finding our interest is I = PxRxT

P (principal) = 675

R (rate) = 10% (we have to turn it into a decimal which is 0.010)

T (time) = 6 years

so :

I = 675 x 0.010 x 6

I = 40.5
