Answer:
d. y minus 8 + 2 less-than-or-equal-to negative 2 + 2
Step-by-step explanation:
Which inequality is equivalent to this one?
<em>y minus 8 less-than-or-equal-to negative 2</em>
y minus 8 + 8 greater-than-or-equal-to negative 2 + 8
y minus 8 + 8 less-than negative 2 + 8
y minus 8 + 2 less-than-or-equal-to negative 2 + 8
y minus 8 + 2 less-than-or-equal-to negative 2 + 2
Take the last option:
y minus 8 + 2 less-than-or-equal-to negative 2 + 2
remove the +2 on each side to get
<em>y minus 8 less-than-or-equal-to negative 2</em>
Answer:
A) 12%
Step-by-step explanation:
Lets assume a random diameter to work with. I will use a diameter of 10.
Circumference = πD
Circumference = π * 10
Circumference = 31.415
Decreasing the circumference by 12%
31.415 * 0.12 = 3.769
31.415 - 3.769 = 27.64
To find out what percent the diameter is reduced by we will find out the new diameter with the new circumference
Circumference = πD
27.64 = π * D
D = 27.64 / π
New Diameter = 8.8
OldD - NewD
10 - 8.8 = 1.2
1.2/10 = 0.12
The diameter decreased by 12%
