C) 17%
D) 14%
The concentration of the mixture made by mixing 6 fl. oz. of a 20% alcohol solution and 4 fl. oz. of a 5% alcohol solutions is 14%
What is an equation?An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the concentration of the mixture, hence:
(6 * 20%) + (4 * 5%) = x * (4 + 6)
1.2 + 0.2 = 10x
x = 0.14 = 14%

Answer:
Step-by-step explanation: if there are 500 pieces of paper and the entire stack is 1.875 inches tall, you devide the total height by 500. I know Deigo is wrong because you can easily reverse check his work by multiplying 0.015 by the total number of papers 500 you will get 7.5 which is not the height of the stack
1.875/500=0.00375
each piece of paper is 0.00375

PLS ANSWER
Answer:
I believe that the answer is 21x+14 and 7(3x+2).
Step-by-step explanation:
I hope this helps, have a blessed day.
Answer:
A. 21x + 14 and 7(3x + 2).
Step-by-step explanation:
23x - 14 + 2x = 21x + 14
25x - 14 ≠ 21x + 14
x + x + 5 = x² + 5
2x + 5 ≠ x² + 5
9x² + 9x + 5 ≠ 18x² + 5
21x + 14 = 7(3x + 2)
21x + 14 = 21x + 14.
Your answer is A, 21x + 14 and 7(3x + 2).

Answer:
r = 62
Step-by-step explanation:
Angles add up to 180 so:
r + r + 56 = 180
2r + 56 = 180
2r = 180 - 56
2r = 124
r = 62

Can someone answer this its just boxplots :)))
Explanation:
The boxplot, aka box-and-whisker plot, is a visual way to represent summary data. Each piece of the boxplot visually tells us one of the five items of a five number summary, which are:
Min = smallest valueQ1 = first quartileMedian = middle most valueQ3 = third quartileMax = largest valueThe median is the vertical line inside the box of the boxplot. The diagram shows that the median is 25. Exactly half of the distribution is below the median, and the other half is above the median. So that means that 50% of the cars get at least 25 mpg.
Describe the data in the table
Answer:
the higher the magnitude, the the lower the frequency.

Answer:
so for the first one, y=4x
meaning y = 4 times x
if y=1, x=4. y=2,x=8 y=3,x=12 etc..
same concept for the other ones.
y=x+6
x=1 then 1+6 = 7, so y=7
x=2 then 2+6 = 8, so y=8
etc
hope this helps

See below
Step-by-step explanation:
7. Let's put points in this equation, 1, 2, and 3 will do.
y = 4x
y = 4(1)
y = 4
(1, 4)
y = 4x
y = 4(2)
y = 8
(2, 8)
y = 4x
y = 4(3)
y = 12
(3, 12)
Plot the points, and draw the line. See the first attached graph.
8. Let's put points in this equation, 1, 2, and 3 will do.
y = x + 6
y = 1 + 6
y = 7
(1, 7)
y = x + 6
y = 2 + 6
y = 8
(2, 8)
y = x + 6
y = 3 + 6
y = 9
(3, 9)
Plot the points, and draw the line. See the second attached graph.
9. Let's put points in this equation, 1, 2, and 3 will do.
y = 2x + 1
y = 2(1) + 1
y = 2 + 1
y = 3
(1, 3)
y = 2x + 1
y = 2(2) + 1
y = 4 + 1
y = 5
(2, 5)
y = 2x + 1
y = 2(3) + 1
y = 6 + 1
y = 7

The line plot represents the amount of water that is poured into six beakers. What is the total amount in ounces of all the water? Explain how you got your answer. Your answer should be as a mixed number in simplest form.
Answer:
69
Step-by-step explanation:
just cant explain this
Answer:
1 7/8 ounces
Step-by-step explanation:
Simple addition:
1/8 + 1/8 = 2/8 = 1/4
1/4+ 1/4 = 2/4
3/8 + 3/8 = 6/8 = 3/4
2/4 + 3/4 = 5/4 = 10/8
10/8 + 5/8 = 15/8 = 1 7/8 oz.

Marsha and Tian are making table decorations for a party. Marsha made 2/9 of a decoration in half and hour. Tian made 2/3 of a decoration in the same amount of time. How much more of a decoration did Tian make in a half and hour?
How much would they make in a half hour if they worked together?
Answer:
4/9 and 8/9
Step-by-step explanation: you have to have a common denominator so you take 3 and 9 and find what they both go into and that number is 9 so take 2/3 and times the top and bottom by 3 to get 6/9 and 2/9 by 1 to get 2/9 once you have those subtract them to get 4/9 and that's your first answer then take them and add so you get 8/9 which is your second answer

Answer:
x = 11°
z = 62°
Step-by-step explanation:
To find the value of z, we can observe that the opposite angle measures 62°. The opposite angle will always be equal, so we can determine that the value of z is 62°.
For the value of x, we can subtract the measures that we have already found from the full 360°. We know that there are two angles measuring 62°, so we can subtract both of them from 360 for a remaining measure of 236°.
In this way, we have only two equal angles left to solve. Since we know that they are equal to each other, we can divide the 236° by two to find what the equation measures. So, 13x - 25 = 118.
Solve this equation for x. First, add 25 to both sides.
13x -25 + 25 = 118 +25
Simplify.
13x = 143
Next, divide both sides by 13 to isolate x.
[tex]\frac{13x}{13}[/tex] = [tex]\frac{143}{13}[/tex]
Simplify.
x = 11
We can check this by substituting 11 for x in the original equation.
13(11) - 25 = 118
So, we know for sure that x = 11.
The answer is x = 11° and z = 62°.
I hope this helped :] Good luck ^^
