Answer:

6pi

Step-by-step explanation:

First find the circumference of the entire circle

C = 2*pi*r

C = 2*pi*4

C = 8pi

We have 3/4 of the circle so multiply the circumference by the fraction of the circle

3/4*8pi

6pi

-4y=-20x+40<br> y+10=5x
mart [117]

Answer:

infinitely many solutions

Step-by-step explanation:

We want to find solution to the system:

-4y=-20x+40

y+10=5x

We make y the subject in the second equation to get;

y=5x-10

We substitute y=5x-10 into the top equation to get:

- 4(5x - 10) =  - 20x + 40

We expand to obtain;

- 20x  + 40=  - 20x + 40

This implies that:

40 = 40

Therefore the system has infinitely many solutions.

Which reason supports the true statement that angle1 and angle8 are supplementary?
elena-s [515]
Angles 1 and 8 are created by line t intersecting with line m.


Line t is called a transversal line, because it intersects 2 parallel lines.

t divides the straight angle formed by m alone, forming the linear pair of angles (1) and (8), whose sum is 180 °, that is they are supplementary.


Answer: (1) and (8) are linear pairs
