Mylen is placing a fence around a circular garden with a 20-foot diameter. How many feet of fencing will Mylen need to buy to enclose the garden? Use 3.14 for pi. Round the answer to the nearest foot.
a 314 ft
b 63 ft
c 1256 ft
d 31 ft
Answer:
63ft
Step-by-step explanation:
Circumference (C) = 2pi x r
radius (r) = diameter/2
r = 10ft
C = 2(3.14)(10)
C = 62.8ft or 63ft
In Harold’s class, there are 7 boys for every 6 girls. Identify three equivalent ratios to compare boys to girls.
Answer: The ratio of 6 /7 represent the number of boys to the number of girls in one classroom. You are given a total number of boys and girls.
So, your ratio has to represent how many boys to the total number of boys and girls in one classroom, or 13.
The proportion becomes, 6 / 13 = x / 78.
Cross multiply getting, 13 * x = 6 * 78
Divide by 13 to solve for x, or x = 36.
There are 36 boys in all of the classrooms and 42 girls in all of the classrooms.
The ratio of boys to girls in all of the classrooms is 36 / 42, or 6 / 7.

Answer:
6. 4x
7. 3y
8. y - 4.5
9. 7/2x + 2
Step-by-step explanation:
6.
x + x + x + x
Combine like terms by adding
4x
7.
4y - y
Combine like terms by subtracting
3y
8.
7y - 4.5 - 6y
Combine like terms by subtracting
1y - 4.5
y - 4.5
4.5 does not have the same variable as the other term in the expression, therefore we cannot do anything further to it
9.
4x + 2 - 1/2x
Combine like terms by subtracting
One like term is a fraction so we must convert the whole number into a fraction with the same denominator
4/1x = ?/2
Cross multiply
4 × 2 = 1x × ?
8 = 2x
This is our new fraction: 8/2x because 4x = 8/2x
Substitute this new fraction into the expression
8/2x + 2 - 1/2x
Combine like terms by subtracting the numerators
7/2x + 2
Neither are like terms so they cannot be added together

Look at Figure 2. What is the measure of x ? ( Hint: you may need to use triangle ACE to help you;) notice the right angle??? NEED HELP ASAP PLEASE
Answer:
60°
Step-by-step explanation:
Let angle BAE = angle ACD = x
BCD = AEC = 60°
EAC + FCA + ECF + AEC = EAC + x + 60° + 60° = 180°
EAC = 60° - x
BAC = EAC + BAE = 60° - x + x = 60°

WILL MARK BRAINLIEST Which of the following represents members of the domain of the graphed function?
Answer:
D
Step-by-step explanation:
Ngl I was confused for a minute. But domain is asking for the x-values and range is asking for the y-values.
You can see the points on the graph are (-4,1), (-2,2), (0, 3), and (2,4).
Because it is asking for the domain, it is asking for the X VALUES of the points you have found above. So the answer is {-4, -2, 0, 2}
So none of those answers look quite right
The reason I picked D is because it is the only one that contains the x values we picked. The rest have numbers outside the domain, such as 3, 4, 5, etc.
HELP! im sooooooooooo confused
Josh ran 14.8 km in the morning. After lunch, he continued running. When he finished the run, he had covered 31.1 km in all. Write an equation that can be used to find how far Josh ran after lunch.
Answer:
14.8 + x = 31.1
Step-by-step explanation:
This is the best equation to put as the answer.
If you want to solve it, this is how you would solve it.
14.8 + x = 31.1
Make it so that the variable x is by it's self.
14.8 + x - 14.8 = 31.1 - 14.8
x = 31.1 - 14.8
Now solve the subtraction problem.
x = 31.1 - 14.8 = 16.3
So, now you have your answer
x = 16.3
To make sure it's correct, use the addition method.
16.3 + 14.8 = 31.1

plz hury i am on a test 100 points and Brainlyeist
Answer:8
Step-by-step explanation:
The prime factors of 24 are 2*2*2*3
The prime factors of 40 are 2*2*2*5
They both share 2*2*2
2*2*2=8
the factors of 48 are 1,2,6,8,12,24,48
the greatest common factor of 60, 84 and 72 is 12
solution
12 times 4 equals 84; 12 times 5 equals 60
the factors of 36 are : 1,2,3,4,6,9,12,18,36
factors of 54 are : 1,2,3,6,9,18,27 and 54
hope this helps :)
