Answer:
61.4
Step-by-step explanation:
The length of two semicircles of diameter 10 is the circumference of a circle of that diameter:
C = πd = 10π ≈ 31.4
The perimeter includes that length plus the lengths of two straight sides that are 15 units each.
P = 31.4 + 2×15
P = 61.4 . . . . units
Answer:
2
Step-by-step explanation:
pass (0,0) (1,2)
slope = (2-0) / (1-0) = 2/1 = 2
3(2x+1) = 7-2(x+5)
6x+3 = 7-2x-10
-3 -3
6x = 7-2x-10-3
+2x +2x
8x = -6

x = -3/4
To find the distance between two numbers on the number line, you have to subtract the smallest one to the greatest one. In this case, the distance from 7 to 10 is 10 - 7 = 3
