There are 21 jars of peanut butter for sandwiches. Each sandwich uses 1/5 of a peanut butter jar. How many sandwiches can be made from all the peanut butter?
Answer: 105 sandwiches can be made from all the peanut butter.
Step-by-step explanation:
Given: Total jars of peanut butter = 21
Part of peanut butter required for each sandwich = [tex]\dfrac15[/tex]
Total number of sandwiches made = ( Total jars of peanut butter ) ÷ (Part of peanut butter required for each sandwich)
[tex]=21\div\dfrac15\\\\=21\times5\\\\=105[/tex]
Hence, 105 sandwiches can be made from all the peanut butter.
Order the numbers from least to greatest.

60 boys in a hostel have food for 30 days. How long would the food last for 72 boys. Tell me how to do it with explanation please
Answer:
The food will last for 25 days with 72 boys
Step-by-step explanation:
Proportions can be used to find the number of days the food will last for 72 boys.
60 boys in a hostel have food for 30 days.
Let x be the number of days for which the food will last
The proportion or product of both scenarios has to be same as the number of days and number of boys are proportional
Which means
[tex]60*30 = 72 * x\\x = \frac{60*30}{72}\\x = 25[/tex]
Hence,
The food will last for 25 days with 72 boys

A store has two different sizes of ice cream the smaller container cost 3.87 for 48 ounces the larger container cost 6.42 which ice cream cost less per ounce
Consider the complete question is "A store has two different sizes of ice cream on sale this week. The smaller container costs $3.87 for 48 ounces. The larger container costs $6.42 for 128 ounces. which ice cream costs less per ounce?"
Given:
The smaller container costs $3.87 for 48 ounces.
The larger container costs $6.42 for 128 ounces.
To find:
Which ice cream costs less per ounce?
Solution:
We know that
[tex]\text{Cost per ounce}=\dfrac{\text{Total cost}}{\text{Number of ounces}}[/tex]
Using this formula, we get
Per ounce cost of small container [tex]=\dfrac{3.87}{48}[/tex]
[tex]=0.080625[/tex]
[tex]\approx 0.08[/tex]
Per ounce cost of larger container [tex]=\dfrac{6.42}{128}[/tex]
[tex]=0.05015625[/tex]
[tex]\approx 0.05[/tex]
Since, 0.08 > 0.05 therefore, the per ounce cost of larger container is less.

Answer:
[tex]\sqrt[7]{x^{3} }= x^{\frac{3}{7} }[/tex]
Step-by-step explanation:
In order to solve this question we need to understand the following.
[tex]\sqrt{x}[/tex] = [tex]x^{\frac{1}{2} }[/tex]
[tex]\sqrt[3]{x} = x^{\frac{1}{3} }[/tex]
[tex]\sqrt[4]{x}= x^{\frac{1}{4} }[/tex]
(Notice that the numerator of the fraction is the power of the x that is being squared)
If you need proof here it is.....
[tex]\sqrt{x} = x^{\frac{1}{2} }[/tex]
[tex](\sqrt{x} )^{2}[/tex] = [tex](x^{\frac{1}{2} } )^{2}[/tex]
x = x
Now that we got that out of the way we can rewrite [tex]\sqrt[7]{x^{3} }[/tex] as........
[tex]\sqrt[7]{x^{3} }= x^{\frac{3}{7} }[/tex]

Liz and Larry are arguing over who makes better chocolate chip cookies. Liz likes to use 3 cups of brown sugar for every 8 cups of flour. Larry prefers to use 2 cups of brown sugar for every 5 cups of flour. Do Liz and Larry use the same ratio of brown sugar to flour?
Answer: No, they don't.
Step-by-step explanation: Liz uses a 3 to 8 ratio of brown sugar to flour while Larry uses a 2 to 5 ration of brown sugar to flour. I hope this helps!
Answer:
The answer is no
Step-by-step explanation:
It is imposibble for Liz and Larry to use the same ratio of brown sugar to flour,
The rotio of liz cup = 3:8
the ratio of larry = 2:7
The ratio of liz cup is greater than the ratio of larry.
so they are deffinetly not the same ratio,
therefore the answer is No

A club raised 175% of its goal for a charity. The club raises $875. What was the goal?
Pls help and thank you
Answer: The goal was $500
======================================================
Work Shown:
x% = x/100
175% = 175/100 = 1.75
Let g be the goal, which is the amount of money the club wanted to raise
175% of goal = 175% of g = 1.75g
The expression 1.75g represents how much money was actually raised, which was $875. Set the two expressions equal to each other. Solve for g
1.75g = 875
g = 875/1.75 ....... divide both sides by 1.75
g = 500
The club's goal was to raise $500
Note how 75% of $500 is 0.75*500 = 375
When they raised 175% of the goal, this means they went 75% overboard and added on 375 additional dollars (on top of the 500 they wanted). So they got to 500+375 = 875 which lines up with the instructions. This helps verify the answer.
Or we can see that 1.75*g = 1.75*500 = 875 which helps confirm the answer as well.
Keiko is getting balloons for her grandfather's birthday party. She wants each balloon string to be 12 feet long. At the party store, string is sold by the yard. If Keiko wants to get 46 balloons, how many yards of string will she need? 1 foot = 1 3 yard
Answer: 184 yards
Step-by-step explanation:
Since she wants each balloon string to be 12 feet long and she wants to get 46 balloons, the total length of strings would be:
= 46 × 12 feet
= 552 feet
Since 1 yard = 3 feet. 552 feet would be converted to yard which would be:
= 552/3
= 184 yards
Jimmy and Alex each have a CD collection. • The number of CDs in Jimmy's collection can be represented by x. • The number of CDs in Alex's collection is 4 times the number in Walter's collection. • The total number of CDs in both collections is 205. What is x, the number of CDs in Walter's collection?
Answer:
x = 41
And, the number of CDs in Walter's collection is 41
Step-by-step explanation:
The computation is shown below;
Given that
The number of CDs in Jimmy collection = x
The number of CDs in Alex's collection = 4x
And, The total number of CDs in both collections is 205
So, the equation is
x + 4x = 205
5x = 205
x = 41
The alex collection is
= 4 × 41
= 164
So, the walter collection is
= 164 ÷ 4
= 41
