Answer:
904.78 m³
Step-by-step explanation:
V = 4/3 × π r³ = 4/3 × π × 6³ = 904.78
(-x + 7)(x + 5)
Bc if you split -x^2 and 35 into 2 parts to get 2x it’ll be x(7)= 7x & -x(5)= -5x —> 7x-5x=2x
(I hope that made sense?)
Answer:
Louis is correct
Step-by-step explanation:
we know that
When multiplying two powers that have the same base, you can add the exponents
so

so
In this problem we have

therefore
Louis is correct
Let x = original price in dollars
x is the original price
9% of this original price is equal to 0.09x
subtract: x - 0.09x = 0.91x
The discount price is equal to 0.91x and it's equal to 90 dollars, so they must be the same value. Ie.
0.91x = 90
0.91x/0.91 = 90/0.91
x = 98.9010989
x = 98.90
So the original price is $<span>98.90</span>
