Anwser: The hotels charge for a call is the same for a 20 minute call.
Step-by-step explanation:
Alrighty, same deal as the last problem, set up a equality, it should look like this:
$1+.80x=$2+.75x
Move the variable to the left of the equation:
.80x-.75x=2-1
Simplify
.05x=1
x=20
Answer:
Step-by-step explanation:
The average length of the weird trapezoidal shape on the left is
(2 m + 10 m)/2, or 6 m. The width is 4 m, so the area is 24 m^2.
The area of the semicircle is (1/2)(pi)(2 m)^2, or 2pi m^2.
Thus, the overall area of the green shape is 24 m^2 + 2pi m^2.

First question:
When you bisect an angle, you create two new equal angles, both measuring half of the original angle. So, if the original angle was 52°, the two angles will be 52/2=26 degrees each.
Note: the picture is not very clear, and I'm not sure the original angle is 52°. It it's not, just divide by 2 whatever measure the angle is.
Second question:
Focus on triangles RQP and RSP:
- They are both right, because Q and S are right angles
- We are given QP=SP
- They share the side RP
So, they are congruent. This implies that angle SRP is 50° as well, and then
QRS = QRP+SRP = 50°+50°=100°
