Answer:
%88.88... and on and on
Formula Nonsense: percentage = b/l then *100 add % sign
so P= 32/36 so 0.888....*100= 88.88... so she made 88%
Answer:
h = 13.333 +693.333/r
Step-by-step explanation:
For h hours, Brandee's pay will be ...
pay = 40r +(h -40)(1.5r) . . . . 40 hours at rate r + overtime (h-40) hours at 1.5r
pay = 40r +1.5hr -60r . . . . . eliminate parentheses
pay = 1.5hr -20r . . . . . . . . . . collect terms
Solving for h, we have ...
pay +20r = 1.5hr . . . . . . . . . . add 20r
h = (pay +20r)/(1.5r) . . . . . . . . divide by 1.5r
For the given pay of 800 +240 = 1040, we have ...
h = (1040 +20r)/(1.5r)
h = 13.333 +693.333/r . . . . . simplify to 2 terms

<em>Additional comments</em>
You need to know r to find the number of hours Brandee worked. She got paid $800 for a presumed 40-hours of regular time, so made r = $20 per hour. The above formula will tell you she worked 48 hours in the pay period.
There are 12 inches in a foot, so we can simply divide the amount of inches (100) by 12 to get the amount of feet.
100ipm/12
Hope this helps!
*ipm stands for inches per minute.
The first
thing to do is to find the roots.
The sum of
the roots, x1 + x2 = -b / a
<span>x1 + x2 = 3
/ 2 </span>
The product
of the roots, x1 * x2 = c / a
<span>x1 * x2 = 5 /
2 </span>
The AM means arithmetic mean and is calculated using the
formula:
AM = (x1 + x2) / 2
AM = (3 / 2) / 2
AM = 3 / 4 = y1
The HM means harmonic mean and is calculated using the
formula:
2 / HM = 1 / x1 + 1 / x2
or
2 / HM = (x1 + x2) / x1 * x2
Rewriting in terms of HM alone on the left side:
HM = 2 x1*x2 / (x1 + x2)
HM = 2 (5 / 2) / (3 / 2)
HM = 10 / 3 = y2
Creating an equation from y1 and y2:
(y – ¾) (y – 10/3) = 0
y^2 – 10/3 y – ¾ y + 30/12 = 0
y^2 - 49/12 y + 30/12 = 0 (ANSWER)
or
<span>y^2 – 4.083y + 2.5 = 0</span>
6 / (x+1) = 1/2
x +1 = 12
x = 11
Answer is d ....(11)
