Answer:
1)
2) 8 3) 0.8 4) ![\sqrt[10]{61}](https://tex.z-dn.net/?f=%5Csqrt%5B10%5D%7B61%7D)
Step-by-step explanation:
The equation for pythagoream theorem is
a^2 + b^2 = c^2 (the caret "^" represents exponents)
A = a side length
B = another side length
C = the hypotnuse which is the slanted side of the right triangle.
To solve these problems plug in the known values into the equation then solve.
We have 60 gallons of 20% antifreeze.
How much 70% antifreeze do we add to get 60% antifreeze?
We'll make "x" the gallons of 70% we must add.
.20 * 60 + .70 x = .60 * (60 + x)
12 + .70x = 36 + .60x
.10x = 24
x = 240 gallons of 70% antifreeze.
