Answer:
20% alcohol = 1 gal
10% alcohol = 9 gal
Step-by-step explanation:
Let
x = 20% alcohol
y = 10% alcohol
x + y = 10 (1)
0.20x + 0.10y = 10*0.11
0.20x + 0.10y = 1.1 (2)
From (1)
x = 10 - y
Substitute x = 10 - y into (2)
0.20x + 0.10y = 1.1
0.20(10 - y) + 0.10y = 1.1
2 - 0.20y + 0.10y = 1.1
- 0.20y + 0.10y = 1.1 - 2
-0.10y = -0.9
y = -0.9/-0.10
y = 9 gal
substitute y = 9 into (1)
x + y = 10
x + 9 = 10
x = 10 - 9
x = 1 gal
20% alcohol = 1 gal
10% alcohol = 9 gal

In your own words, what is a radical expression?
Answer:
In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher. When the radical symbol is used to denote any root other than a square root, there will be a superscript number in the 'V'-shaped part of the symbol. For example, 3√(8) means to find the cube root of 8. If there is no superscript number, the radical expression is calling for the square root.
The term underneath the radical symbol is called the radicand.

Use the points (2, 2485.6) and (6, 1172.5) to write an equation of the line of fit in slope-intercept form. Let x be the years since 2010 and let y be the number of CDs in millions sold.
Answer:
y = -328.275x + 1829.05
Step-by-step explanation:
In this case, we need to write an equation of this form:
y = ax + b (1) a: slope b: intercept
In order to calculate the slope, we need to use the following expression:
a = y₂ - y₁ / x₂ - x₁ (2)
So, we have two points here, so, from these points we can identify each of the elements so we can determine the slope.
Point 1: (2, 2485.6)
Point 2: (6, 1172.5)
The slope of this equation will be:
a = 1172.5 - 2485.6 / 6 - 2
a = -328.275
Now that we have the slope, to get the intercept "b", we just use any of the given points, and replace in the general equation (1) to solve for b:
2485.6 = -328.275(2) + b
b = 2485.6 - 656.55
b = 1829.05
With the value of a and b, we can write the general equation of the line for this:
y = -328.275x + 1829.05Hope this helps

angle A = 18° and angle B = 25°. Find angle C.
Answer: Angle C: 137 degrees
Step-by-step explanation:
A+B+C=180
18+25+C=180
C=137
Step-by-step explanation:
triangle add U to 180
18 + 25 = 43
180 - 43 = 137 degree is c

How many 0.8 liter glasses can be filled by a 6.8 liter pitcher?
Answer:
8.5 glasses
Step-by-step explanation:
6.8L / 0.8L = 8.5 glasses
Answer:
8 glasses
Step-by-step explanation:
You divide [tex]6.8/0.8[/tex]
This gives you 8.5 glasses
since 9 glasses is too much, at 7.2 liters. The maximum glasses possible is 8 assuming you're not filling a half of the glass which would be 8.5 glasses.

Step-by-step explanation:
Answer:
C. 350 pounds
Step-by-step explanation:
Looking at the chart, week 22 would be between the week 20 and week 25 marks. As a result, the weight should be between 275 and 425 pounds. As a result, A is out. Week 22 will be bigger than week 20 (275), so B is also out. Week 22 is in between Week 20 and 25, so it isn't bigger than Week 25's pumpkin; D is out for this reason. That leaves C, 350 pounds, as our answer.

Solve the equation below. Simplify if necessary.
-4/7v = -8 2/3
Show how you did it please :)
Answer:
15 1/6
Step-by-step explanation:
change -8 2/3 into an improper fraction = -26/3
-4/7v = -26/3
cross-multiply:
3(-4v) = (-26)7
-12v = -182
v = 182/12
v = 15 1/6
