Answer:
6 miles per hour
Step-by-step explanation:
speed = distance/time
speed = 1/2÷1/12 which is the same as
1/2 x 12/1 = 6
6 miles per hour.
or ou could change the 1/2 to become 0.5
and the 1/12 to become 0.083333333
and divide 0.5 ÷ 0.083333333 = 6.000000024
rounded to one decima place become 6.0
6 miles per hour
Answer:
10 units
Step-by-step explanation:
Area of a triangle is
= Area
where h is the height, and b is the base
We can substitute these values into the area equation and get:

Multiply both sides by 2:
x * 10 = 100
Divide both sides by 10:
x = 10
The missing side is 10 units long
Answer:
C = 2πr = 16.3
2(3.14)r = 16.3
r = 16.3/6.28
r = 2.5955414
Area: A = πr2
A = 3.14(2.5955414)2
A = 21.15366242 
Step-by-step explanation:
The answer would be 21.2 
The answer would be d. Because the identity property of addition is that if you add zero to any number the number stays the same
