Answer:
x=-25
Step-by-step explanation:
Inverse variation
xy =k
We know x and y
20*5 =k
100 =k
So the formula is
x y = 100
We know y = -4
x (-4) = 100
Divide each side by -4
-4x/-4 = 100/-4
x = -25
The answer tothis question is two
Answer:
C. 24
Step-by-step explanation:
a^2 + b^2 = c^2
a and b are the legs of the right triangle. c is the hypotenuse.
a^2 + 10^2 = 26^2
a^2 + 100 = 676
a^2 = 576
Since "a" is to the 2nd power, the opposite would be to square root it.
Square root of 576 is 24.
x = 24
19.6% because 98 multiplied by .20 which is 20 percent is 19.6
