Answer:
144
Step-by-step explanation:
V=PIr^2h
PI=3
V=3r^2h
r=2 h=12
V=3(2^2)12
V=3(4)12
V=12(12)
V=144in^3
Answer:
two digits to the right
Step-by-step explanation:
When multiplying a decimal by 102 you would need to move the decimal point two digits to the right. This is because we are multiplying by a hundred number. When multiplying any whole positive number by a decimal, we need to move the decimal point to the right one less than the amount of digits that the positive whole number has. For example, a thousand (1000) has 4 digits so we move the decimal point of the product to the right by 3.
Examples:
102 * 0.02 = 2.04
1000 * 0.02 = 20
10000 * 0.02 = 200
Answer:
Step-by-step explanation:
we know that
![1\ nickel=\$0.05](https://tex.z-dn.net/?f=1%5C%20nickel%3D%5C%240.05)
![1\ quarter=\$0.25](https://tex.z-dn.net/?f=1%5C%20quarter%3D%5C%240.25)
Let
x------> the number of nickel coins
y-----> the number of quarter coins
we know that
![x+y=22](https://tex.z-dn.net/?f=x%2By%3D22)
-----> equation A
----> multiply by 100 both sides
-----> equation B
Substitute equation A in equation B and solve for y
------>
2 cheques (money coming in)
= 2×5
= $10
30+10= $40
2 bills (money going out)
=2×4
= $8
40-8=$32
The end balance is $32.
Hope this helps!
