Answer:
[tex](5p + 11) + (8p - 4) \\ = ( 13p + 7)[/tex]
C. (13p+7) is the right answer.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.
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.
Rewrite the radical expression as an expression with a rational exponent.

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]

As an estimation we are told 5 miles is 8 km.
Convert 17.6 km to miles.
Answer:
17.6 kilometers are equal to 11 miles.
Step-by-step explanation:
Given that:
8 kilometers = 5 miles
Unit rate in terms of kilometer.
1 kilometer = 5/8 miles
Now,
We have to convert 17.6 kilometers in miles
17.6 kilometers = [tex]\frac{5}{8}*17.6[/tex]
17.6 kilometers = [tex]\frac{5}{8}*\frac{176}{10}[/tex]
17.6 kilometers = 11 miles
Hence,
17.6 kilometers are equal to 11 miles.

The time of a race is 13.7seconds rounded to 1 decimal place.If the time was x seconds find the inequality in x
Answer:
13.65 ≤ x < 13.75
Step-by-step explanation:
Let x represent the time in seconds. Since the time is 13.7 seconds when rounded to 1 decimal place, hence for this to be possible the minimum value of x is given as x ≥ 13.65 because 13.65 rounded to 1 decimal place is 13.7 seconds. Also, the maximum value of x is given as 13.75 because 13.75 rounded to 1 decimal place is 13.8 seconds.
Therefore the inequality to represent x is:
13.65 ≤ x < 13.75

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

Step-by-step explanation:
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
