Step-by-step explanation:
First we make the denominator of the fraction equal
82 15/20
24 16/20
18 15/20
We then subtract
82 15/20 - 24 16/20
81 35/20 - 24 16/20 =

What is the total area of the figure below?
Answers
To find the area of this figure you need to separate it into different sections.
First to find the area of the triangle on the left is multiple 8 by 3, giving the area of 24.
Second find the area of the rectangular shape towards the left, and ignore the triangle ends on both sides for now. To find the area of the rectangle multiply 10 by 9.
Lastly, to find the area of both triangles on both ends is to multiply 9 by 3. The three is found by subtracting 10 from 16 and dividing it by two.
Adding all the areas together gives you the answer = 141 in^2

The revenue, in dollars. of a company that produces video game systems can be modeled by the expression 52 +
2t - 80. The cost in dollars, of producing the video game systems can be modeled by 5.22 -+ 100, where x is the
number of video game systems sold. If profit is the difference between the revenue and the cost, what expression
represents the profit?
Profit can be modeled by the polynomial expression
If 1,000 video game systems are sold, the company's profit is $
Answers
Answer:
1). Profit = 3x - 180
2) Profit of selling 1000 video games = $2820
Step-by-step explanation:
Expression for the revenue = 5x² + 2x - 80
Expression for the production cost of the video games = 5x² - x + 100
Since, profit is the difference between the revenue and the cost,
Expression for the profit will be,
Profit = Revenue - Cost
= (5x² + 2x - 80) - (5x² - x + 100)
= 5x² + 2x - 80 - 5x² + x - 100
= 3x - 180
Here, x = Number of video games sold
If number of video games sold = 1000
Profit = (3×1000) - 180
= 3000 - 180
= $2820
A pole that is 3.3 m tall casts a shadow that is 1.4 m long. At the same time, a nearby building casts a shadow that is 47.5 m long. How tall is the building?
Round your answer to the nearest meter.
Answers
Answer:
[tex]112\:\mathrm{m}[/tex]
Step-by-step explanation:
If you were to draw a diagram, you could form two similar triangles using the pole and the building (unsolvable otherwise). Since these triangles are similar, we can write the following proportion:
[tex]\frac{3.3}{1.4}=\frac{h}{47.5}[/tex], where [tex]h[/tex] is the height of the building.
Solving, we get:
[tex]h=\frac{47.5\cdot 3.3}{1.4},\\h\approx \fbox{$112\:\mathrm{m}$}[/tex] (rounded to the nearest meter as requested in the problem).

Given the exponential equation 3* = 243, what is the logarithmic form of the equation in base 10? (5 points)
log, 243
log, 3
log, 3
log, 243
log,03
log, 243
log, 243
Answers
Answer:
[tex]x = \frac{log\ 243}{log\ 3}[/tex]
Step-by-step explanation:
Given
[tex]3^x = 243[/tex]
Required
Express as a logarithm
[tex]3^x = 243[/tex]
Take log of both sides
[tex]log\ 3^x = log\ 243[/tex]
Apply the following law of logarithm
[tex]log\ a^b = b\ log\ a[/tex]
So, the expression becomes:
[tex]log\ 3^x = log\ 243[/tex]
[tex]x\ log\ 3 = log\ 243[/tex]
Divide both sides by log 3
[tex]\frac{x\ log\ 3}{log\ 3} = \frac{log\ 243}{log\ 3}[/tex]
[tex]x = \frac{log\ 243}{log\ 3}[/tex]
Hence, the expression in base 10 is:
[tex]x = \frac{log\ 243}{log\ 3}[/tex] or [tex]x = \frac{log_{10}\ 243}{log_{10}\ 3}[/tex]

what is the equation, in point-slope form, that is perpendicular to the given line and passes through the point (-4,-3)?
Answers
Answer:
C. y + 3 = ¼(x + 4)
Step-by-step explanation:
✔️First, find the slope of the given line on the graph that it is perpendicular to:
Slope (m) = ∆y/∆x = -4/1 = -4
Thus, the slope of the line that is perpendicular to the given line would be the negative reciprocal of -4.
The negative reciprocal of -4 = ¼
✔️Find the equation in point-slope form, y - b = m(x - a) using slope and a point on the line:
Substitute m = ¼, (a, b) = (-4, -3) into y - b = m(x - a):
y - (-3) = ¼(x - (-4))
y + 3 = ¼(x + 4)
Which multiplication equation is related to the division equation one ninth ÷ 5 = ___?
five times one twenty fifth equals one ninth
one forty fifth times five equals one ninth
one forty fifth times one fifth equals one ninth
five times one fifteenth equals one ninth
Answers
Answer:
one forty fifth times five equals one ninth
Step-by-step explanation:
In division, the number being divided is the dividend or numerator, the denominator is the number we use to do the division while the result is the quotient and there may be a reminder.
For example, if
a/b = c
then
a = b * c
hence
1/9 ÷ 5
= 1/9 * 1/5
= 1/45
This means that
1/45 * 5 = 1/9
Hence the related multiplication equation related to the division equation one ninth ÷ 5 is one forty fifth times five equals one ninth
Division expression are the expression in which one number is divided by other. Multiplication equation is related to the division equation one ninth divided by five is one forty fifth times five equals one ninth. Thus the option 2 is the correct option.
Given-The given division equation is the fraction 1/9 divided by the number 5. That is,
[tex]\dfrac{\dfrac{1}{9} }{5} =\dfrac{1}{45} [/tex]
Division expressionDivision expression are the expression in which one number is divided by other
1) Five times one twenty fifth equals one ninth-This can be written as,
[tex]5\times \dfrac{1}{25} =\dfrac{5}{25} [/tex]
[tex]5\times \dfrac{1}{25} =\dfrac{1}{5} [/tex]
Which is not equal to the the given division expression.
2) One forty fifth times five equals one ninth-This can be written as,
[tex]\dfrac{1}{45}\times5 =\dfrac{1}{9} [/tex]
This is equal to the the given division expression.
3) One forty fifth times one fifth equals one ninth-This can be written as,
[tex] \dfrac{1}{45}\times\dfrac{1}{5} =\dfrac{1}{225} [/tex]
Which is not equal to the the given division expression.
4) Five times one fifteenth equals one ninth-This can be written as,
[tex]5\times \dfrac{1}{15} =\dfrac{1}{3} [/tex]
Which is not equal to the the given division expression.
Hence multiplication equation is related to the division equation one ninth divided by five is one forty fifth times five equals one ninth. Thus the option 2 is the correct option.

A chemist has a bottle of a 1% acid solution and a bottle of a 5% acid solution. She wants to mix the two solutions to get 100 ml of a 4% acid solution. Follow the steps below to find how much of each solution she should use.
Part 2 out of 3
Use the information in the table to write a system of equations.
Answers
Answer:
12% alkaline
Step-by-step explanation:
The amount of 1% acid solution she needs to mix is 25 ml while the percentage of 5% acid solution she needs to mix is 75 ml.
Given to us
A chemist has a bottle of a 1% acid solution and a bottle of a 5% acid solution.
She wants to mix the two solutions to get 100 ml of a 4% acid solution.
Assumption
Let the amount of 1% acid solution be x ml, and the amount of 5% acid solution be y ml.
Total Amount of the Final SolutionAs the chemist wants to mix the two solutions to make 100 ml of solutions, therefore,
amount of 1% acid solution + amount of 5% acid solution = 100ml
x + y = 100.....equation 1
Solving for y,
y = 100 - x
What is the % of the acid in the mixture?We know that the mixture is having a 4% concentration and is 100 ml in volume.
[tex](1\%)x+(5\%)y = (4\%)100\\0.01x+0.05y=0.04\times 100\\[/tex]
Substitute the value of y,
[tex]0.01x+0.05(100-x)=0.04\times 100\\\\0.01x + (0.05\times 100)-(0.05\times x) = 4\\\\0.01x + 5 -0.05x =4\\\\0.01x-0.05x = 4-5\\\\0.04x = 1\\\\x=\dfrac{1}{0.04}\\\\x = 25\ ml[/tex]
Substitute the value of x in equation y,
[tex]x+y = 100\\25 +y =100\\y = 100-25\\y=75\ ml[/tex]
Hence, the amount of 1% acid solution she needs to mix is 25 ml while the percentage of 5% acid solution she needs to mix is 75 ml.
