Referring to the figure, the circle shown is drawn on grids. Find
A ÷ r and A ÷ r2.
a. 7.1, 3 c. 16, 4
b. 14.2, 3.2 d. 12, 2.7
Answer:
B. 14.2, 3.2
Step-by-step explanation:
diameter: 9 (count each box as 1)
d/2 = radius --> radius: 4.5
Area of a circle= πr^2
A= 63.6172
A/r = 63.6172/4.5 = 14.1
A/r^2= 63.6172/(4.5)^2 = 3.14

Hugo is pumping regular gas into his truck. Write and solve an absolute value equation to represent how many gallons of gas will be pumped when the total is $25 plus or minus $0.50.
Answer:
10
Step-by-step explanation:
We need to find out how many gallons of gas will be pumped when the total is $25 plus or minus $0.50. So what we do is $25 divided by $2.50 which will give us how many times the gas has been pumped. The answer to that is 10 which means the gas has been pumped 10 times.

A company manufactures cell phone cases. The length of a certain case must be within 0.25 mm of 125 mm, as shown (figure is not to scale). All cases with lengths outside of this range are removed from the inventory. How could you use an absolute value inequality to represent the lengths of all the cases that should be removed? Explain.
Answer:
Step-by-step explanation:
the length must be within plus or minus .25 mm of 125 mm.
if x is the length of the case, then:
absolute value of (x - 125) must be <= .25
this is shown as |x - 125| <= .25
when the expression within the absolute value sign is positive, the expression becomes (x - 125) <= .25
add 125 to both sides of this inequality to get:
x <= 125 + .25 = 125.25
when the expression within the asbolute value sign is negative, the expression becomes (x - 125) >= -.25
add 125 to both sides of this inequality to get:
x >= 125 - .25 = 124.75
the manufactured case must have a length that is greater than or equal to 124.75 mm and less than or equal to 125.25 mm.
otherwise it is removed from the inventory.
It appearxs that the other tutor talked a lot about your question; but he did not answer it.
The inequality that represents the lengths of all cases that should be removed from the inventory is

Which expression represents the sequence of operations described below?
subtract 4 from 8, then multiply the result by 5
Answer:
5(8-4)
Step-by-step explanation:
You need to do the subtraction first, so put it in parenthesis because otherwise subtraction comes after multiplication if you follow PEMDAS, then put a five outside to multiply it by the difference of 8 and 4.
Answer: 5 x (4-8) or 5(4-8)
Step-by-step explanation:
First, put 4-8 in brackets, because you need to do it first and without brackets you would do the multiplication first (because of BEDMAS). Then, you would multiply your subtraction by 5.
Hope this helps :)

PLS HELP ME!!!! THIS IS DUE TOMORROW!!! v - 1/2 = -9/8
What is v?
Answer: v=-5/8
Step-by-step explanation:
v - 1/2 = -9/8
(v - 1/2 = -9/8)*8 ==> multiply the equation by 8 to get rid of fractions
8v - 8*1/2 = -9
8v-8/2=-9
8v-4=-9
8v=-5
v=-5/8
Answer: v=-5/8

find the area and circumference of each circle. Use pi in your answer (example: radius = 8, or diameter = 14).
Answer:
Solutions below.
Step-by-step explanation:
First, we have to define each of the formulas first.
Area of Circle =
[tex]\pi {r}^{2} [/tex]
Circumference of Circle =
[tex]2\pi \: r[/tex]
With the above formula above, we can find the Area and Circumference for each circle.
Circle A:
Radius = 8
Area =
[tex]\pi {(8)}^{2} = 64\pi {units}^{2} [/tex]
Circumference =
[tex]2\pi(8) = 16\pi \: units[/tex]
Circle B:
Diameter = 14 units
Radius = 14 ÷ 2 = 7 units
Area =
[tex]\pi {(7)}^{2} = 49\pi {units}^{2} [/tex]
Circumference =
[tex]2\pi(7) = 14\pi \: units[/tex]
