For each ounce of the product, let
x = ounces of moisturizing lotion used,
y = ounces of self-tanning lotion used.
The sum of the two lotions per ounce is equal to one ounce. Therefore
x + y = 1 (1)
Moisturizing lotion costs $0.70 per ounce.
Self-tanning lotion costs $22 per ounce.
Because the product costs $1.30 per ounce. Therefore
0.70x + 22y = 1.30 (2)
From (1), obtain
y = 1 - x (3)
Substitute (3) into (2).
0.70x + 22(1 - x) = 1.30
0.70x - 22x + 22 = 1.30
-21.3x = -20.7
x = 0.9718 ounces
From (3), obtain
y = 1 - 0.9718 = 0.0282 ounces.
A batch of the product is 700 ounces. Therefore the amount of self-tanning lotion used is
700*y = 700*0.0282 = 19.74 ounces
Answer: 19.74 ounces
THE PARABOLA OPENS DOWN (WHICH IS MAXIMUM ) AND X=1/2
A is the answer to this question
The length can be 18 and the width can be 2.
18 x 2 = 36
Or the length can be 12 and the width can be 3.
12 x 3 = 36
The length can also be 9 and the width can be 4.
9 x 4 = 36
Using the distance formula, there is a Y difference of 6 and a X difference of 7. Create a triangle with those side lengths and solve for the hypotenuse. Sqrt85 is the exact answer. 9.2195 is the rounded.
