What is 1 7/15 + 3/9

Mathematics
1 answer:
kolbaska11 [484]3 years ago
8 0

Answer:

1 and 36/45

Step-by-step explanation:

First, you have to make the denominators the same so that you can add them.

The smallest number that both 15 and 9 are factors of is 45.

Since you had to multiply 15 by 3 to get 45, you need to multiply 7 by 3 as well. this leaves with the fraction  1  21/45.

You multiplied 9 by 5 to get 45 so now you need to multiply 3 by 5 as well leaving you with the fraction 15/45.

Now all you have to do is add 1 21/45 + 15/45.

15 + 21 = 36 leaving you with your answer:

1 36/45

Hope this helps!

An oil tank in the shape of a cylinder has a diameter of 40 feet and a height of 32 feet. Which expression can be used to find t
Volgvan

The volume of a cylinder is pi*r^2*h

The radius is half the diameter, so 40/2=20, and the radius is 20 ft.

Plugging in: pi*20^2*32=pi*400*32=12800pi=40212.38597

So the volume is about 40212.4 ft^3 and the expression we used is pi*20^2*32

Hope this helped!
