56.7 should be the right answer
- 2 1/3 * 1 1/2
change to improper fractions
-2 1/3 =- (3*2+1)/3=-7/3
1 /12 = (2*1+1)/2 = 3/2
-7/3 * 3/2 = -7/2 * 3/3 = -7/2
Change back to a mixed number
7/2 = 3 with 1 left over
-3 1/2
Answer: - 3 1/2
Answer:
Scott is wrong because he did not add the diameter that connects the arc
the fence is 41.12 feet. He would buy 42 feet
Step-by-step explanation:
Circumference of a semicircle = πr + d
π = pi = 3.14
d = diameter = 16
r = radius = 16/2 = 8
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
( 3.14 x 8) + 16 = 41.12 feet
Hello,
The function is y=4x+8.
We exchange x and y ==>x=4y+8
and we seach y:
4y=x-8 ==>y=(x-8)/4 ==> y=x/4-2
