Answer:
2x= 40°
5x= 100°
Step-by-step explanation:
2x on opposite angle because it is an isosceles triangle
2x+ 2x+ 5x = 180° (angles of a triangle)
9x= 180
x= 180/9
x= 20°
Sub
2(20)= 40°
5(20)= 100°
Answer:
The graph should look something like this.
Step-by-step explanation:
Answer:
Option A 
Step-by-step explanation:
we know that
The perimeter of the rectangle is equal to

we have

-----> equation A
substitute the value of L in the equation A
Find the perimeter

The area would be 25π inches.
Since the cross-section goes through the center of the sphere it will be a circle. The area of a circle is given by A = πr²; for our circle, since the diameter is 10 inches, the radius is 5;
A = π(5²) = 25π
Answer:
Step-by-step explanation:
$ 4 per ride and 0.75 per mile
y = 0.75x + 4.....with x being # of miles and y being total cost
if a person only had $ 20....so sub in 20 for y and solve for x
20 = 0.75x + 4
20 - 4 = 0.75x
16 = 0.75x
16 / 0.75 = x
x = 21.33 (or 21 1/3) miles <=====
