The circumference of a circle is 7 m.
What is the area of the circle?
1. 3.5pi m^2
2. 12.25pi m^2
3. 14pi m^2
4. 49pi m^2
Answer:
2. 12.25pi
Step-by-step explanation:
circumference = diameter × pi
diameter = 7
area of circle = pi radius^2
radius = 3.5
3.5^2 = 12.25
answer = 12.25 pi

(that's the only one i know, sorry!)
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
20: 1, 2, 4, 5, 10, 20

The GCF is 4 because that is the highest number that can divide both 20 and 28 evenly.
Which math operation determines the following pattern?
1,4, 16, 64, ..?
Answer:
Multiplication, as you are multiplying each term by 4:
1*4 =4
4*4 = 16
16*4 = 64
Then, you can calculate the next term: 64*4= 256
Answer:
The given pattern can be obtained by a 'multiplication' operation.
Thus, option (C) is correct.
Step-by-step explanation:
Given the pattern
1, 4, 16, 64, ..
From the given pattern, it is clear that every next term can be obtained by multiplying the previous term by 4.
For example, the 2nd term 4 can be obtained by multiplying the previous term by 4.
i.e. 1×4 = 4Similarly, the 3rd term 16 can be obtained by multiplying the previous term (2nd term) by 4.
i.e. 4×4 = 16Also, the 4th term 64 can be obtained by multiplying the previous term (3rd term) by 4.
i.e. 16×4 = 64In a nutshell, the next term (5th term) can be obtained by multiplying the previous term (4th term) by 4.
i.e. 64×4=256This indicates that the following pattern can be obtained by a 'multiplication' operation.
Thus, option (C) is correct.

The radius of a circle with area A can be approximated using the formula r = the square root of A/3 . Estimate the radius of a wrestling mat circle with an area of 452 square feet. Round to the nearest integer.
Answer: 12
Step-by-step explanation:
Given:
A = 452
r = √A/3
Step 1: Substitute 452sqf for A
r = √452/3
Step 2: Solve
452 ÷ 3 = 150.66∞
√150.66∞ = 12.27∞
12.27∞ rounded to the nearest integer equal 12

The expression x + 0.25x can be used to determine a 25% increase in the number of blog views from last month to this month. What expression shows this another way?
Answer:
1.25x
Step-by-step explanation:
Given that :
25% Increase in number of blog views can be expressed as (x + 0.25x)
Another way to make this representation is :
Total number of blog views + 25% of total
Total should add up to 100%
Let number of views = x
Hence,
(100% + 25%) of x
125% of x
125%x
= 1.25x

Ackson wants to divide a 0.75-pound box of trail mix into small bags. Each of the bags will hold LaTeX: \frac{1}{8}\:1 8pound of trail mix. How many bags of trail mix can Jackson fill?
Answer:
6 bags will be filled
Step-by-step explanation:
Here, we want to know the number of bags of trail that can be filled
From what we have in the question, each bag will hold 1/8 = 0.125
So we want 0.75 split into smaller bits of 0.125 each
The number of possible fillings will be;
0.75/0.125 = 6

–81 ≥ –6 – n Please help
Answer:
n ≥ 75
Step-by-step explanation:
-81 ≥ -6 -n
+6 +6
-75 ≥ -n
divide both sides by negative 1 to get rid of the negative sign in front of the n
75 ≥ n
flip the sign because you divided by a negative
75 ≤ n
or
n ≥ 75

A music club membership costs $15 to start and $8 per cd. Write an equation.
Answer:
y = 8x + 15
Step-by-step explanation:
Let x represent the number of cds, and let y represent the total cost.
Since each cd is $8, we can represent the extra cost from cds with the term 8x.
And, since the membership costs $15, this cost can be represented in the equation by +15.
Put these together:
y = 8x + 15 will be the equation representing this
