If 4 gal of pure ethanol are added to 46 gal of 2% ethanol how much of the final solution do you have? How much ethanol is contained in the mixture? What is the strength (percentage) of ethanol in the mixture?
Answer:
100 i belive
Step-by-step explanation:
you add 4+46=50x2=100
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is 4 gal of pure ethanol is added to 46 gal of 2% ethanol.
In 46 gal of 2% ethanol, we have (46 x 0.02) = 0.92 gallons of pure ethanol.
When 4 gal of pure ethanol is added, total ethanol in the mixture = 4 + 0.92 = 4.92 gallons
Total mixture quantity in gallons = 46 + 4 = 50 gallons
The percentage of the ethanol in the mixture will be -
(4.92/50) x 100 = 9.84%
Therefore, the percentage of the ethanol in the mixture will be 9.84%.

Show all work to multiply (2+√-25)(4-√-100)
Answer:
-42Step-by-step explanation:
given the expression;
(2+√-25)(4-√-100)
Note that √-25 = √-1 * √25
√-100 = √-1 * √100
According to complex number, √-1 = i
√-25 = 5i
√-100 = 10i
The expression becomes
(2+5i)(4-10i)
Open the parentehsis;
= 2(4)-20i+20i-50i²
= 8-50i²
Since i² = -1
The expression becomes;
8-50i² = 8-50(-1)²
8-50i² = 8-50 = -42
Hence the product of the expression is -42

A bookstore costs $96 a day to keep open, and it spends $12 for each book that it sells. If each book sells for $18, what is the break-even point
for this bookstore?
Answer: The break even point is when they have sold 16 books and have made $288
Step-by-step explanation: The costs are modeled in the equation y = 12x + 96. x is the number of books sold.
The earnings are modeled by he equation y = 18x.
Substitute 18x for y and solve for x.
18x = 12x + 96 Subtract 12x from both sides.
6x = 96 Divide both sides by 6
x = 16
Substitute into the original equations to solve for y
y = 12(16) + 96
y = 192 + 96
Y = 288
y = 18(16)
y = 288

What is -2(3x - 9) + 5x = -10
Answer:
x=28
Step-by-step explanation:
-2(3x-9)+5x =-10
now we times -2 to to the inside of the parenthese
giving us
-6x+18 +5x= -10
add like terms
add -6x and 5x
-1x+18=-10
now we add like terms of the constants
minus 18 on both sides
-1x=-28
now divide by -1
x = 28
Answer:
x = 28
Step-by-step explanation:
First, remove the parentheses by distributing -2.
-6x + 18 + 5x = 10
Next, collect the like terms.
-x + 18 = -10
Next, move the constant to the right-hand side and change its sign.
-x = -10 - 18
Next, calculate the difference
-x = -28
Lastly, change the signs on both sides of the equation.
x = 28
These are the steps to answer this equation.
Describe how to find the mean, median and mode of a set of data. what does each mean
Answer:
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

What is the Area of the Sector?In circles, a sector is said to be a part of a circle made of the arc of the circle together with its two radii. This means that it is a portion of the circle formed by a portion of the circumference (arc) and radii of the circle at both endpoints of the arc.
The formula for Area of a sector is given as;
θ/360 * πr²
where;
θ is the central angle of the sector
r is radius
Now, looking at the given options we can say that the only one that represents the area of the sector is;
A = n/360 * πr²
where n is the central angle of the sector'
Given data ,
Let the measure of the arcs of the circle be
The measure of angle ∠ABC = 28°
The measure of arc mAC = 80°
The measure of arc mDE = 24°
So , the difference of arc measures mAC - mDE = 80 - 24
The difference of arc measures mAC - mDE = 56°
And , measure of angle 2(∠ABC ) = 56°
Hence , the measures of arcs of circle is solved

Answer:
Step-by-step explanation:
m∠2=71° because they are vertical angles so are congruent
those 4 angles in the midle will add up to 360°
∠3+∠5=360-2*71=218 so
m∠3=218/2=109°
m∠5=109°
mostly use that the sum of angles in a Δ add to 180
m∠1=180-47-71=62°
m∠4=180-109-36=35°
m∠6=180-42-109=29°
use that opposide ∠s in a quadrinateral add to 180
m∠7=180-47-35-29= °69
m∠8=180-42-62-36= °40
