21 bleachers are the minimum needed
Step-by-step explanation:
First we have to find out the common number of them.
For that purpose, the first number should be divided by next number.
100/20 = 5
20/4 = 5
4/0.8 = 5
we have found that 5 is the common number.
0.8/5 = 0.16
therefore the answer is c
Answer:
4/20=1/5
Step-by-step explanation:
The price the widgets should be sold for, to the nearest cent, for the company to make the maximum profit is 62.13
<h3>Quadratic equation</h3>
y = -14x² + 1035x - 10266
- solve the quadratic equation
-14x² + 1035x - 10266 = 0
x = -b ± √b² - 4ac / 2a
= -1035 ± √1035² -4(-14)(-10266) / 2(-14)
= -1035 ± √1071225 - 574896 / -28
= -1035 ± √496329 / -28
x = 1035 / 28 ± √496329 / 28
x = 11.80 or 62.13
The maximum value of x is 62.13
