Answer:
The increase = $0.12
The new price = $1.27
Step-by-step explanation:
1.15 divided by 10% = 0.115 = 0.12
0.12 + 1.15= 1.27
They cancel out each other
Imagine if you were multiplying
-2 * -3
you would get 6
if you did
-2 * 3
you would get -6 because there isn't another - to cancel it out
I learned it that when you have a negative before a negative, put parenthesis around the second number with the negative, so it looks like this
-(-2)
if you look at the -(- it looks like a plus sign
that probably doesn't make much sense but we cancelling it out is just a rule, we don't really know why we do it
Answer:
1570
Step-by-step explanation:
the formula for surface area of a cylinder is:
A= 2πrh + 2πr²
π aka pi = 3.14
r = 10
h = 15
so now plug in the numbers
A = 2(3.14)(10)(15) + 2(3.14)(10²)
A = 942 + 2(3.14)(100)
A = 942 + 628
A = 1570
