Answer:
A. 0.08 B. 0.09 and C. 12-inch hopefully im right
y = mx + c
7 = 4(-8) + c
c = 39
The equation is y = 4x + 39
y - 7 = 4 ( x - (-8))
y -7 = 4 (x +8)
Answer:
.80
or
0.80
Step-by-step explanation:
80 is out of 100, which is other words is .80 or 0.80
Answer:
c
Step-by-step explanation:
Answer:
radius = 5 units
area of a circle = 15.7units²
Step-by-step explanation:
given that the circumference of a circle = 31.4
radius = ?
recall that the formulae for finding the circumference of a circle = 2πr
circumference of a circle = 2 x 3.14 x r
31. 4 = 6.28r
divide both sides by the coefficient of r which is 6.28
31.4/6.28 = 6.28r/6.28
5 = r
radius = 5 units
therefore the radius of the circle whose circumference is 31.4 units is evaluated to be 5units
to find the area of the circle
recall the formula = πr²
area of a circle = 3.14 x 5²
area of a circle = 3.14 x 25
area of a circle = 15.7units²
