4 liters of 2% milk contains 8% cholesterol. A container of skim milk contains 2% cholesterol. How many liters of skim milk need to be added to the 4 liters of 2% milk to create a mixture with 4% cholesterol?
Answers
To solve this problem, we can set up an equation based on the amount of cholesterol in the mixture.
Let's assume that x liters of skim milk need to be added to the 4 liters of 2% milk.
The amount of cholesterol in the 4 liters of 2% milk is 8% of 4 liters, which can be calculated as (8/100) * 4 = 0.32 liters of cholesterol.
The amount of cholesterol in the x liters of skim milk is 2% of x liters, which can be calculated as (2/100) * x = 0.02x liters of cholesterol.
The total amount of cholesterol in the mixture is the sum of the cholesterol in the 2% milk and the skim milk, which should be equal to 4% of the total volume of the mixture. So, we have:
0.32 + 0.02x = (4/100) * (4 + x)
Simplifying the equation:
0.32 + 0.02x = 0.04(4 + x)
0.32 + 0.02x = 0.16 + 0.04x
0.02x - 0.04x = 0.16 - 0.32
-0.02x = -0.16
Dividing both sides by -0.02:
x = (-0.16) / (-0.02)
x = 8
Therefore, 8 liters of skim milk need to be added to the 4 liters of 2% milk to create a mixture with 4% cholesterol.
To solve this problem, we can use the following equation:
4+x4×8+x×2=4
This equation represents the ratio of the total cholesterol to the total volume of the mixture. The numerator is the sum of the cholesterol from the 2% milk and the skim milk, and the denominator is the sum of the volumes of the 2% milk and the skim milk. The equation is equal to 4 because we want the mixture to have 4% cholesterol.
To find x, we can simplify and solve for x:
4+x32+2x=4
32+2x=16+4x
16=2x
x=8
Therefore, we need to add 8 liters of skim milk to the 4 liters of 2% milk to create a mixture with 4% cholesterol.

Answers
Answer:
\(x=\frac{1}{r} +1\)
Step-by-step explanation:
\(r=\frac{1}{x-1}\)
\(r(x-1)=1\)
\(x-1=\frac{1}{r}\)
\(x=\frac{1}{r} +1\)
Answer:
\(x=\dfrac{1+r}{r}\)
Step-by-step explanation:
Given equation:
\(r=\dfrac{1}{(x-1)}\)
Multiply both sides by (x - 1):
\(\implies r(x-1)=\dfrac{1}{(x-1)} \cdot (x-1)\)
\(\implies r(x-1)=1\)
Expand the brackets:
\(\implies rx-r=1\)
Add r to both sides:
\(\implies rx-r+r=1+r\)
\(\implies rx=1+r\)
Divide both sides by r:
\(\implies \dfrac{rx}{r}=\dfrac{1+r}{r}\)
\(\implies x=\dfrac{1+r}{r}\)

Is Figure BBB a scale copy of Figure AAA?
Answers
Reason - if the scale factor of a and b was 2, the dimensions of a would be 4, 7.2 and 10 not the ones present on A
The ratios of corresponding side lengths are not equal.
Therefore, Figure B is not a scale copy of Figure A.
Here, we have to determine if Figure B is a scale copy of Figure A, we need to compare the corresponding sides of the two triangles and check if the ratios of their side lengths are equal.
Figure A has side lengths: 3.6, 2, and 5.
Figure B has side lengths: 8.9, 4, and 11.3.
Let's check if the ratios of corresponding side lengths are equal:
Ratio of corresponding side lengths of A and B:
3.6 / 8.9 ≈ 0.4045
2 / 4 = 0.5
5 / 11.3 ≈ 0.4425
The ratios of corresponding side lengths are not equal.
Therefore, Figure B is not a scale copy of Figure A.
In order for two triangles to be scale copies of each other, all corresponding side lengths must have the same ratio.
Since the ratios of side lengths in Figure A and Figure B are not equal, they are not scale copies of each other.

2(4x-3)-8=4+2x please solve this linear equation I need help
Answers
Answer:
x = 3
Step-by-step explanation:
Perform the indicated multiplication. We get
8x - 6 - 8 = 4 + 2x
Combining the x terms results in:
6x - 14 = 4
Isolate x by adding 14 to both sides:
6x = 18
Find x by dividing both sides by 6:
x = 18/6 = 3
x = 3
The solution or the value of x for the given linear equation 2(4x-3)-8=4+2x is x = 3.
Given that:
2(4x - 3) - 8 = 4 + 2x
Use the distributive property on the left-hand side.
(2 × 4x - 2 × 3) - 8 = 4 + 2x
(8x - 6) - 8 = 4 + 2x
Using the associative property:
8x + (-6 - 8) = 4 + 2x
8x - 14 = 4 + 2x
Subtract both sides by 2x.
8x - 2x - 14 = 4
6x - 14 = 4
Add 14 on both sides.
6x = 18
Divide both sides by 6.
x = 3
Hence, the value of x is 3.

A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.
Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Answers
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500

Answers
It will take 50 minutes for the two containers to have the same amount of water.
Based on the information given, the equation to solve the question will be:
800 - 6m = 1000 - 10m
Collect like terms
-6m + 10m = 1000 - 800
