Answer:
7.5 gallons
Step-by-step explanation:
2.5/5+x=0.2
This question is based on the concept of solving an equation. Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.
Given:
5 gallons of 50% acid solution to get a 20% solution.
According to question,
Let it be x gallons of water should be added to 5 gallons of 50% acid solution to get a 20% solution.
Now, forming the equation, we get,
0.50 ( 5 ) = 0.20 ( x + 5 )
Simplifying the equation.
We get,
2.5 = 0.2x + 1
1.5 = 0.2 x
x = 7.5
Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.

Of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed or left-handed students? Explain. Write your answers in simplest form.
what is the fraction for the right handed people
Answer:
Step-by-step explanation:
12% is equivalent to 12/100. This reduces to 3/25. Thus, 3/25ths of the students are left-handed. The corresponding fraction for the right handed people is (25-3)/25, or 22/25ths. There are more right-handed people (22/25ths) versus left-handed people.

==========================================================
Explanation:
She starts off finding the mean of the data. So she adds up the values to get 48+54+57+62+69 = 290, and then divides by 5 to get the mean of 290/5 = 58. That explains why there's a 58 in the first row of the second column.
---------------------
For the next step, she subtracts 58 from each data item. If the result is negative, then go with the positive version (ie apply the absolute value)
|48-58| = 10|54-58| = 4|57-58| = 1|62-58| = 4|69-58| = 11This leads to the list 10,4,1,4,11 which goes in the first slot labeled "drag and drop an item here". This is the list of distance values each item is from the mean.
---------------------
The last thing to do is find the mean of the set {10,4,1,4,11}
add: 10+4+1+4+11 = 30
divide by five: 30/5 = 6
The mean absolute deviation (MAD) is 6
This represents the average distance each data value is from the mean. The MAD tells us how spread out the data is. It's similar to the standard deviation.

A holiday meal cost $12.50 a person plus a delivery fee of 30$. Which equation is right?
1. y=30+12.50x
2. y= 12.50+30
3. 12.50x=30
4. y=12.50+30x
Answer:
1. y = 12.50x + 30
Step-by-step explanation:
A holiday meal cost $12.50 a person plus a delivery fee of 30$
Let x = number of people ordering a meal and y = total cost
It cost 12.50 per person so the cost regarding the number of people that orders food can be represented by 12.50x.
There is also a $30 delivery fee.
So the total cost would (y) = 12.50x + 30
The answer would be 1. 12.50 and 30 just swapped places.
The weight of Kyle's dog increased from 29.7 pounds to 48.9 pounds in an 8 month period. What was the average weight increase per month?
Answer:
per month means we divide by the months
here is our formula
we do 48.9-29.7 to see the increase, and divide by the months to see how much per month
(48.9-29.7)/8
We get 2.4, meaning the average weight increase per month is 2.4

Annette is surveying people in the city about their interest in a new shopping mall. She found that 180 people, or 37.5% of those surveyed, do not want a new mall. How many people did Annette survey?
We want to find the total number of people that Annette surveyed given that we know a percentage and the number that the percentage represents.
We will find that the number of people that Annette survey is 480.
To get the solution:
Let's assume that she surveyed a total of X people.
Then we can write the equivalence:
100% = X
We know that the 37.5% is equivalent to 180 people, then we can write:
37.5% = 180
The two equations are:
100% = X
37.5% = 180
Now we can take the quotient between these two equations to get:
(100%/37.5%) = X/180
Solving for X we get:
(100%/37.5%)*180 = X = 480
So the total number of people surveyed is 480.
Answer:
480 people
180/X × 100 = 37.5%
180 × 100 = 37.5 × X
18000 ÷ 37.5 = 37.5 × x ÷ 37.5
480 people = x

Question: 5/12 − 2/5= 1/60
A. The answer 1/60 is not reasonable because 5/12 is closer to 1 than to 1/2, and 2/5 is closer to 0 than to 1/2, making the difference close to 1/2.
B. The answer 1/60 is not reasonable because 5/12 is closer to 1/2 than to 1, and 2/5 is closer to 0 than to 1/2, making the difference close to 1/2.
C. The answer 1/60 is reasonable because both fractions are closer to 1/2 than they are to 0, making the difference close to 0.
D. The answer 1/60 is reasonable because both fractions are closer to 1 than they are to 1/2, making the difference close to 0.
Answer:
C
Step-by-step explanation:
It is reasonable: the answer is both reasonable and correct because 5/12 - 2/5 = 1/60. This is because using cross multiply, 5 x 5/12 = 25/60, 12 x 2/5 = 24/60. 25/60 - 24/60 = 1/60.
Both are closer to half: half out of 12 would be 6/12 and 0 would be 0/12, so 5/12 is closer to half because 5/12 is closer to 6/12 than 0/12. Half out of 5 would be 2.5/5 and 0 would be 0/5, so 2/5 is closer to half because 2/5 is closer to 2.5/5 than 0/5.
The difference is close to 0: 1/60 is very close to 0. It's only worth 0.016.
What is the volume of this solid?
Most Precise Answer = Round to the nearest hundredth
Approximate Answer = Round to the nearest tenth if necessary
?
Answer:
4188.79 yd^3
Step-by-step explanation:
The formula for the volume of a sphere is ...
V = 4/3πr^3
A sphere with a diameter of 20 yards has a radius of 10 yards, so its volume is ...
V = 4/3π(10 yd)^3 = 4000π/3 yd^3 ≈ 4188.79 yd^3
Rounded to tenths, that's approximately 4188.8 yd^3.
