The answer would be a . $43.2 because your multiplying the number by 0.08
Answer:
The unit price at Price-Club is $0.2158 per ounce.
The unit price at Shop Mart is $0.2925 per ounce.
Step-by-step explanation:
Price Club:
12-ounce box of crackers for $2.59
So
12 ounces - $2.59
1 ounce - x
The unit price at Price-Club is $0.2158 per ounce.
Shop Mart:
1-pound box of crackers for $4.68.
1 pound is 16 ounces. So
16 ounces - $4.68
1 ounce - x
The unit price at Shop Mart is $0.2925 per ounce.
Answer:
How to Cube A Number
To cube a number, just use it in a multiplication 3 times .
A cube root goes the other direction:
3 cubed is 27, so the cube root of 27 is 3
Answer:
V ∝ g
⇒ V = Kg
When V = 36 and g = 4, substitute into the formula above
⇒ 36 = K x 4
K = 9
The equation then becomes
V = 9g
when g = 11
V = 9 x 11
V = 99
Step-by-step explanation:
Answer:
x^2 + 2x^2 + 1 = x^4 + 2x^2 +1
Step-by-step explanation:
pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs
substitute what we know
(x^2 -1)^2 + (2x)^2 = (x^2+1)^2
FOIL
(x^2 -1)^2 = (x^2-1 ) (x^2-1) = x^4 -x^2 - x^2 +1 = x^4 -2x^2 +1
(2x)^2 = 4x^2
(x^2+1)^2 = (x^2+1 ) (x^2+1) = x^4 +x^2 +x^2 +1= x^4 + 2x^2 +1
substitute these back in
x^4 -2x^2 +1 +4x^2 = x^4 + 2x^2 +1
combine like terms
x^2 + 2x^2 + 1 = x^4 + 2x^2 +1
Since the left and right side are equal, this is a right triangle
