Answer:
175.93 feet
Step-by-step explanation:
First, you divide 18 by 2 to get the radius which is 9. Then you do nine squared. Lastly, you do 64 times 3.14 to get 254.47 (rounded)
Now, you do 5 squared which is 25. Then you multiply 25 by 3.14 to get 78.54 (rounded).
Now you subtract
254.47 - 78.54 = 175.93
Note: I rounded these in the example, the decimal places still go on so the rounded answers may not subtract to the correct answers because all the decimal points weren't shown, but the answer is correct.

Answer:
C
Step-by-step explanation:
Write the expression out
factor it
[tex](\frac{(x+1)(x-1)}{6x})(\frac{3x(x)}{x(x+1)})[/tex]
cancel out all everything that is the same and appears on both the top and the bottom
Cancel out:
(x+1)
(x)
(x)
leaves you with
[tex]\frac{3(x-1)}{6}[/tex]
3 goes into 6 '2' times so the 3 in the numerator cancels out too. The 6 in the denominator turns into a 2
This leaves you with the final answer of
[tex]\frac{x-1}{2}[/tex]
Answer:
C
Step-by-step explanation:
after factoring them
they become:
[tex]\frac{(x+1)(x-1)3x^2}{6x^2(x+1)}[/tex]
after dividing the numerator and denominator by 3x^2(x+1)
it becomes (x-1)/2

Find the slope and y-intercept of the line in the graph. Express the answers as simplified fractions, if
necessary.
Answer:
Slope: [tex]\frac{7}{5}[/tex]
Y-intercept: -5
Step-by-step explanation:
If the equation of the line is not given but is graphed we can do in this way:
First, it's very simple to find the y-intercept: is -5 as you can see (the line touch the points -5 in the y line).
You know that the slope can be find by having two points (now we have the A(0; -5) (the y-intercept point).
As you can see, the line touch also the B(5; 2) perfectly.
Now we simply use this formula for find the slope:
[tex]s=\frac{yB-yA}{xB-xA}[/tex]
Let's substitute the value:
[tex]slope=\frac{2+5}{0+5}[/tex]
[tex]slope = \frac{7}{5}[/tex]
Answer:
Slope: 7/5
Y-intercept: -5

A closet containing 120 pieces of clothing is made of sweaters, jeans, and skirts. The ratio of sweaters to jeans is 8:3, and the ratio of jeans to skirts is 3:4. If 4 of the pairs of jeans were taken out of the closet and were replaced by 4 skirts, what will be the new ratio of jeans to skirts?
A. 3:4
B. 4:5
C. 5:9
D. 1:11
Answer:
C, 5:9
Step-by-step explanation:
Answer:
5/9
Step-by-step explanation:
Context for variables
sw: number of sweaters
j: number of jeans
sk: number of skirts
The following three equations are established from the question:
sw + j + sk = 120
sw/j = 8/3
j/sk = 3/4 or sk/j = 4/3
Dividing the first equation by j, we get:
sw/j + j/j + sk/j = 120/j
8/3 + 1 + 4/3 = 120/j
5 = 120/j
j = 120/5 = 24
sw = 24*8/3 = 64
sk = 24*4/3 = 32
After the replacement the new number of jeans and skirts are:
j' = 24 - 4 = 20
sk' = 32 + 4 = 36
the new ratio of jeans to skirts is:
j'/sk' = 20/36 = 5/9
Jess surveys her class to find out how many hours of sleep her classmates get per night. She lists the number of hours for each student,
8, 11, 10, 9, 9, 10, 11, 8, 10, 9, 8, 9, 7, 9, 10, 9, 11
Which question can be answered with Jess's data?
A. Who gets the most hours of sleep per night?
8. Who gets 7 hours of sleep per night?
C. How many hours of sleep does Jess get per night?
D. How many students get 8 hours of sleep per night?
Answer:
D
Step-by-step explanation:
Just by looking at the data, you cannot answer A, B, or C because they are asking for who. There is no information on the data on WHO each piece of data is referring to. You can only answer D, which asks for HOW MANY. You can count how many 8s there are and answer the question.
One triangle has a weight of 6 grams. What is the weight of one square?
Answer:
Assuming you want them to weigh the same the answer would be 3 grams
Step-by-step explanation:
Because... 6 × 3 = 18 3 × 4 = 12
18 + 12 = 30
6 × 4 = 24 3 × 2 = 6 24 + 6 = 30 therefore
squares = 3
Hope this helps not sure if I am right.
Answer: 3 grames
3 because half of 6 is 3 that’s why and that it is balance so I know they are equal

Answer:
x = 37
Step-by-step explanation:
The angle with a measure of 74 degrees and the angle labeled "2x" are vertical angles
Vertical angles are congruent ( equal to each other )
Hence, 74 = 2x
^(note that we just created an equation that we can use to solve for x)
Now we solve for x
74 = 2x
step 1 divide each side by 2
74 / 2= 37
2x / 2 = x
we're left with x = 37
