Circumference C=2pi*r
But in question C=40pi
This implies that 2pi*r=40pi
This implies that r=20 in.
d=2*r=40 in.
Hope this helps :)
Answer:
-9x+12
Step-by-step explanation:
(-8x + 5) - (x – 7)
Distribute the minus sign
(-8x + 5) - x + 7
Combine like terms
(-8x -x+ 5+7)
-9x +12
Answer:
AOC = 124°
Step-by-step explanation:
Angle on a straight line is 180°, therefore, the sum of the three angles shown is 180;
This can be written like so:
(3x + 94) + (x + 30) + (2x - 4) = 180
This equation can be solved to find x:
6x + 120 = 180
6x = 180 - 120
6x = 60
x = 10
AOC = 3(10) + 94
= 30 + 94
= 124
Answer: 7
Step-by-step explanation: its correct, trust me
Answer:
+10
Step-by-step explanation:
The law of integers states that a negative number divided by a negative integer would result in a positive integer, therefore;
-40 / -4 = 10
