Answer:
So we want to divide by .
The first thing we are going to do is factor the denominator of the first fraction and the denominator of the second one:
- For our first fraction:
Now we can rewrite our first fraction:
- For our second fraction:
Now we can rewrite our second fraction:
Last but not least, we can express our division as a fraction and simplify:

A Ben & Jerry's Ice Cream factory makes 170 quarts of ice cream in 10 hours. How many quarts will the factory make in 36 hours?
The Ben & Jerry's Ice Cream factory will make
quarts of ice cream in 36 hours.
Answer:
612 quarts
Step-by-step explanation:
First, let's set up this situation into a proportion.
[tex]\frac{170}{10} = \frac{x}{36}[/tex]Now, let's simplify the proportion.
[tex]\frac{170/10}{10/10} = \frac{x}{36}[/tex] [tex]\frac{17}{1} = \frac{x}{36}[/tex]As you can see, we have to multiple one by thirty-six to get to thirty-six. Whatever we do the denominators, we have to do to the numerators. Thus, 17 multiplied by 36 is 612 quarts.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Answer:
612 quarts
Step-by-step explanation:
If 170 quarts of ice cream is made in 10 hours. Then, in 1 hour (170/10) = 17 quarts of ice cream are made.
Therefore, in 36 hours (17×36) = 612 quarts of ice cream are made

A man spent two fifth of his salary on rent ,one-quater on food and one-eight on transport.What fraction does he have left? (a)³¹/40 (b)²³/⁴ (c)²¹/⁴⁰ (d)⁹/⁴⁰
Answer:
Hi! You just have to take his salary as a unity (one) and substract the fractions you are given. For example; lets say you have a cake (one) and then you eat 1/8 of it. You would be left with [tex]1-\frac{1}8}[/tex] of the original cake.
Step-by-step explanation:
Salary: [tex]1[/tex]
Spent [tex]\frac{2}{5}[/tex] : [tex]1-\frac{2}{5}[/tex]
Spent [tex]\frac{1}{4}[/tex]: [tex]1-\frac{2}{5} -\frac{1}{4}[/tex]
Spent [tex]\frac{1}{8}[/tex]: [tex]1-\frac{2}{5} -\frac{1}{4} -\frac{1}{8}[/tex]
REMAINING: [tex]1-\frac{2}{5} -\frac{1}{4} -\frac{1}{8}[/tex]
Operate using LCM: [tex]\frac{40-16-10-5}{40} = \frac{9}{40}[/tex]

Select all the true statements (select 2)
If 16 adults go to the zoo, then 9 students can go.
If 8 more adults go to the zoo, that means there will be room for 12 fewer students.
If no adult chaperones were needed, 30 students could go to the zoo.
If ten students go to the zoo, then 15 adults can go.
Answer:
if no adult ones went, 30 students could go.
Step-by-step explanation:
If the cost of the student was 8, and there were 30 students going theoretically, this would be the most logical answer, since 8 multiplied by 30 is exactly 240

there is a flat fee of $18
there is an incremental fee of $0.08 per ball which can be shown as [tex]0.08B[/tex]
so the amount that Carolina will spend would be [tex]18+0.08B[/tex]

find the area of the circles
Answer:
1) 7.069 cm^2
2) 12.567 cm^2
3) 19.635 cm^2
4) 3.142 yd^2
5) 38.485 yd^2
6) 50.266 yd^2
Step-by-step explanation:
This problem is a repetition of the formula Area = [tex]\pi[/tex]*[tex]radius^{2}[/tex]
You are given the diameter of each circle. The radius is 1/2 of the diameter, so, for example circle 1 has a diameter of 3 cm which means the radius is 3/2 cm and the area is A = [tex]\pi * (3 cm /2)^{2}[/tex] = 7.069 cm^2
don't forget your units. Either cm or yd squared

Answer:
A. 25.6 ft
B. 28.2 ft
Step-by-step explanation:
The triangle inequality tells you the length of any side of a triangle lies between the sum and difference of the lengths of the other two sides:
43.7 -30.7 < ? < 43.7 +30.7
13.0 < ? < 74.4
Only two answer choices fall within that range:
25.6 ft, 28.2 ft
Exponential functions
Answer: -15^2
Step-by-step explanation: It goes down by -225 every time so the exponent form would be -15^2. Just keep on subtracting 225 every number. Add 225 for the 0x only.
Consider a circle. The length of the arc for the central angle of 45 degrees is 16cm, then the total circumference (perimeter) of the circle is
a) 126cm
b) 128cm
c) 162cm
d) 182cm
Answer:
b
Step-by-step explanation:
the arc length is calculated as
arc = circumference (C) × fraction of circle , then
16 = C × [tex]\frac{45}{360}[/tex] = C × [tex]\frac{1}{8}[/tex] ( multiply both sides by 8 )
128 = C
circumference of circle is 128 cm
Bryan is sitting on a bench in the mall. He noticed that 18 out of the last 60 men who walked by had a beard. Considering this data, how many of the next 90 men who walk by should Bryan expect to have a beard?
Answer:
27
Step-by-step explanation:
every 30 men = 9 men with beards
you have 30 3 times in 90 so you get 27
60÷2=30
18÷2=9
30 men normal = 9 men with beards
90÷30=3
3×9=27
Answer:
27 is correct
Step-by-step explanation:
18 out of the last 60 men who walked by had a beard.
based on the given condition formulate
[tex]\boxed{\frac{18}{60}=\frac{x}{90} }[/tex]
[tex]\boxed{60x=18(90)}[/tex]
[tex]\boxed{\frac{18~x~90}{60} }[/tex]
[tex]\boxed{x=27}[/tex]
Another way to solve↓60÷2=30
18÷2=9
30 men normal = 9 men with beards
90÷30=3
how many of the next 90 men who walk by
you have 30 × 3 = 90 so you get 27
3 × 9 = 27
Therefore the correct answer is 27
Hope this helps!

11. On a math exam, two students scored 95, five students scored 87,
three students scored 73, four students scored 63, and one student
scored 40. What was the class average?
Answer:
About 76%.
Step-by-step explanation:
To find the average of numbers, you add all of the numbers together and divide the total by the number of numbers. In this case, your numbers would be 95 twice, 87 five times, 73 three times, 63 four times, and 40 once. The total number of numbers is 15, and the total of all of the exam scores if you add them up is 1136. Finally, you would divide 1136 by 15, which would be 75.7333333, which would be an average of about 76%.

Alexia ran three laps around her neighborhood each lap isn’t 1 3/8 miles
What’s the best estimate of the number of miles alexia ran!!!!!?!?!?!?!?!?!,
HELP!?!!!?!?!
Im going to assume you meant each lap *Is* 1 3/8 miles.
Answer:
4 1/8
Step-by-step explanation:
If you take 1 and multiply by 3, you get 3. Pretty simple. When you multiply 3/8 by 3, its also easy. You just multiply the top number. 3 times 3=9. So, you have 9/8. And when your top number is equal or greater than your bottom number its more than a whole. So, you have 1 1/8. Then you add the 1 to the 3, and you get 4, you have 1/8 left over, so your answer is 4 1/8

Answer:
slope is 1/4； y intercept is -2
Step-by-step explanation:
read your textbook carefully
you note that you are given two point the x-intercept and y-intercept:
(8,0) and (0,-2) respectively.
before doing exercise, you need to know what is the slope formula (read your book).
slope formula is the change in y over the change in x.
or you can perceive that slope mean when x move forward one unit, what is change in y( how many units the y move).
Hope help( read your textbook carefully)

Answer:
Rate of change is slope
To calculate slope its
y2 - y1 / x2- x1 = slope
Just choose 2 random sets from the table.
I’m gonna go with (0,-10) and (2,20)
Now calculate slope
20 - (-10) / 2 - 0
Solve.
30 / 2
30/2 = 15
Rate of change is 15
Daniel and Sydney are getting high-speed Internet access at the same time. Daniel's provider charges $60 for installation and $45.95 per month. Sydney's provider has free installation and charges $57.95 per month. After how many months will Daniel and Sydney have paid the same amount for high-speed Internet service?
Answer:
5 months
Step-by-step explanation:
Daniel's provider charges $60 for installation and $45.95 per month. Sydney's provider has free installation and charges $57.95 per month
Let x = number of months
Daniel = 60 + 45.95x
Sydney = 0 + 57.95x
Equate both equations
60 + 45.95x = 0 + 57.95x
Collect like terms
60 - 0 =57.95x - 45.95x
60 = 12x
Divide both sides by 12
x = 60 / 12
= 5
x = 5 months
Daniel and Sydney would have paid the same amount for high-speed Internet service after 5 months
