#1---> let the number you are trying to find be x for the following questions
30%*x=15
x=15/30%
x=50
#2
10%*x=14
x=14/10%
x=140
#3
(4/32)*100
is the same as (1/8)*100= 12.5%
#4
1%* x=11
x=11/1%
x=1100
by the way * means multiply
120% of 12 is 14.4.I got this by doing this:
12/x=100/120
<span>(12/x)*x=(100/120)*x - </span>we multiply both sides of the equation by x
<span>12=0.833333333333*x - </span>we divide both sides of the equation by (0.833333333333) to get x
<span>12/0.833333333333=x </span>
<span>14.4=x </span>
<span>x=14.4</span>
a) ∠PQR=65° (alternate interior angles theorem)
∠PRQ = 60° (linear pair)
x = 55° (angles in a triangle add to 180°)
b) ∠APQ and ∠PQR are congruent alternate interior angles.
Answer:
60%
Step-by-step explanation:
33/55, giving you 60%.
You find the circumference and multiply it by the central angle. If the central angle is in degrees, you divide that by 360. If the central angle is in radians, you divide by 2pi.
