Answer:
they are 6 possibilities in one roll
Step-by-step explanation:
Old - new is 1 so than after that it would be 1/5 than 1/5 x 100 = 20%
Options:
A.) square root
B.) exponential
C.) absolute value
D.) cube root
Answer : A) square root
We know area of square having side 's' = s* s = 
For example
Area of square = 
To find side we take square root
Area = 
16 =
Take square root on both sides
4= side
Betsy knows that the area of the rug is A square feet.
Area A =
So answer is square root.
Let X = the 29% alloy and Y = the 60% alloy.
They want a total of 80kg, so you have X +Y = 80
Rewrite that to get X = 80-Y
You also want 0.20X + 0.60Y = 0.52(80)
Replace X with 80-y:
0.20(80-y) + 0.60y = 0.52(80)
Simplify:
16 - 0.20y + 0.60y = 41.6
Combine like terms:
16 +0.40y = 41.6
Subtract 16 from each side:
0.40y = 25.6
Divide both sides by 0.40
y = 25.6 / 0.40
y = 64
Now you have Y replace y with 80 in X = 80-Y
X = 80 - 64
X = 16
They need 64 Kg of the 60% alloy and 16 Kg of the 20% alloy.
