100%/x%=40/26
<span>(100/x)*x=(40/26)*x - W</span>e multiply both sides of the equation by x
<span>100=1.53846153846*x - W</span>e divide both sides of the equation by (1.53846153846) to get x
<span>100/1.53846153846=x </span>
<span>65=x </span>
x=65
<span>Now we have: </span>
<span>26 is 65% of 40
Good luck~ Sans</span>
Recall that a circle of radius 2 centered at the origin has equation
where the positive root gives the top half of the circle in the x-y plane. The definite integral corresponds to the area of the right half of this top half. Since the area of a circle with radius
is
, it follows that the area of a quarter-circle would be
.
You have
, so the definite integral is equal to
.
Another way to verify this is to actually compute the integral. Let
, so that
. Now
Recall the half-angle identity for cosine:
This means the integral is equivalent to
Maria has 5 more (+5) more than 6 times the number of pencils (6x) Bill has
p = pencils
6p + 5, or C, is your answer
Jamie is 3 years younger than Ray. Ray is y years old
Jamie's age is y - 3
y - 3, or B, is your answer
