Answer:
37.5 percent
!!
Step-by-step explanation:
26 - 12 = $14
She will need to spend more than $14 now
The answer is the second one from the top
You can solve this using the Quadratic Formula, x =
.
a = 1, b = -12, c = 59
x =
Multiply 4 and 1
x =
Multiply 2 and 1
x =
Multiply -4 and 59
x =
Square 12
x =
Subtract
x =
You can't find the square root of negatives, so factor the -92 out.
x =
You
can find the sqaure of 4, so take that out.
x =
Split the expression into two parts
x =
(+ or -)
The 2 in the numerator and the 2 in the denominator cancel each other out
x =
(+ or -)
Divide 12 by 2
x = 6 (+ or -)
Now, split the solution into the plus and minus parts.
Answer:
h = s / π.r²
Step-by-step explanation:
the given equation is s = π.r².h
Now if we have to calculate the value of h from the given formula then we will solve it so that h remains alone on one side of the equation.
This only possible when we divide term on both the sides by π.r²
s/π.r² = π.r².h/π.r²
h = s / π.r²
Therefore h = s / π.r² is the right option.
