Answer:
68
125 percent (calculated percentage %) of what number equals 85? Answer: 68.
Answer:
68
Step-by-step explanation:
First, let us assign a variable x, for the (blank) in the problem.
Next, converting the question into a math equation, we get:
125% * x = 85.
Solving for x, we get:
1.25x = 85
x = 68.

A school reserved a banquet hall for the spring dance. In addition to a $100 deposit, each couple must pay $20. If the total cost of the banquet hall is $1, 140. Compare and contrast the steps you used to solve the problem algebraically and arithmetically.
Step-by-step explanation:
1.)20x + 100 = 1440
-Let the number of couples be x. So, the total amount paid by all the couple’s are $20x. School paid $100 as security, so the total amount paid is
$ (20x + 100)
2.) 20x = 1440 - 100 ⇒ 20x = 1040
X = 52
3. ) The security money is $100, so the couples paid $1440- 100 = $1040 in total. As the couples paid $ 20 each than- [tex]\frac{1040}{20}[/tex] = 52

describes the function?
A. The function is always increasing.
B. The function is never increasing.
C. The function is increasing when x > 0.
D. The function is increasing when x < 0.
Answer:
C. The function is increasing when x > 0.
Step-by-step explanation:
Statement best describes the function, The function is increasing when x > 0.
We have given that,
A. The function is always increasing.
B. The function is never increasing.
C. The function is increasing when x > 0.
D. The function is increasing when x < 0.
What is the increasing function?
A function is increasing when the y-value increases as the x-value increases, like this It is easy to see that y=f(x) tends to go up as it goes along.
We have to determine the statement best describes the function.
Therefore,The function is increasing when x > 0.

Answer:

Step-by-step explanation:
Answer:
Answer is C
Step-by-step explanation:
It tells you on the graph paper that 1 square is 6 meters.
The problem says the Post Office is 60 meters long, in its longest dimension
The outine on the graph paper is 10 squares long on the longest side.
10 squares to represent 60 meters is 60 meters/10 squares = 6 meters per square
So we are shown in more than one way that a square on the graph paper represents a length of 6 meters.
Now, for the answers A,B,C, and D.
A is wrong because it says 6 squares for 1 meter. But it is actually the other way around, 6 meters for 1 square.
In B, C, and D they get the 6 meters /1 square part right. But these are proportions, where two fractions are stated to be equalt to each other. Which proportion is true?
There is an easy way to check!
IF a/b = c/d, for real, then ad = bc. (The product of the means equals the product of the extremes.) That is a rule in proportions, and is always mathematically true as long as there are no undefined terms (like zero in a denominator).
So if ad = bc, then B says that 360 = 10. False.
If ad = bc, then C says that 60 = 60. True.
If ad = bc, then D says that 360 = 10. false.
The answer is C

Jason makes a credit card purchase for $3000 that compounds interest daily. The APR is 4%. How much interest is earned on Jason's card after 1 year if Jason makes no payments?
The amount of interest earned on Jason's card after 1 year is $
Step-by-step explanation:
step 1. A = P(1 + r/n)^nt. this is the compounding equation where n is the number of compounds in a time t and P is the original amount. r is the rate.
step 2. A = 3000(1 + .04/365)^(365(1))
step 3. A = 3122.43. this is the total amount owed on the credit card which includes principle and interest. the interest is less 5he principle
step 4. 3122.43 - 3000 = 122.43

No; the domain values are at regular intervals and the range values have a common factor 0.25. b. No; the domain values are not at regular intervals although the range values have a common factor. c. Yes; the domain values are at regular intervals and the range values have a common factor 4. d. Yes; the domain values are at regular intervals and the range values have a common factor 0.25.
Answer:
D
Step-by-step explanation:
No the function is not an exponential function as the domain values are not at regular intervals although the range values have a common factor.
What is exponential function?The exponential function is a function which is formed by the unit e which is equal to 2.718.
How to identify function?The differences between x-values are -1, -1, -1, -2 . . . . not a constant difference
The ratios of y-values are 2/8 = 0.5/2 = 0.125/0.5 = 0.25 . . . . a constant difference
The domain values do not have a common difference shows the common factor of the range values which are of no use. So, the function is not exponential.
Hence the table does not show exponential function in any way because the domain values are at regular intervals and the range values have a common factor 0.25.

Solve the following system of equations.
2x+y=3
I= 2y - 1
x=
y=
Note: I am assuming your second equation is:
x = 2y - 1
Answer:
The solution to the system of equations is:
x = 1y = 1Step-by-step explanation:
Given the system of equations
2x+y=3
x = 2y - 1
solving the system of equations using the elimination method
[tex]\begin{bmatrix}2x+y=3\\ x=2y-1\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}2x+y=3\\ x-2y=-1\end{bmatrix}[/tex]
Multiply x-2y=-1 by2: 2x-4y=-2
[tex]\begin{bmatrix}2x+y=3\\ 2x-4y=-2\end{bmatrix}[/tex]
subtracting the equations
[tex]2x-4y=-2[/tex]
[tex]-[/tex]
[tex]\underline{2x+y=3}[/tex]
[tex]-5y=-5[/tex]
now solve -5y = -5 for y
[tex]-5y=-5[/tex]
Divide both sides by -5
[tex]\frac{-5y}{-5}=\frac{-5}{-5}[/tex]
Simplify
[tex]y=1[/tex]
For 2x+y=3 plug in y=1
[tex]2x+1=3[/tex]
subtract 1 from both sides
[tex]2x+1-1=3-1[/tex]
Simplify
[tex]2x=2[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}=\frac{2}{2}[/tex]
Simplify
[tex]x=1[/tex]
Therefore, the solution to the system of equations is:

This is a dotted line so we can automatically eliminate, b, e, g, h, and j. The shading in greater than, so we can eliminate a, and d.
Now all we have left are c, f and *i,
*(because if converted to y intercept the sign will flip because the y is negative in this equation.)
Now convert to y intercept form (y=mx+b).
Flip the sign because some are negative.
C. y>(-5/2)x+0
F. y>-2x+9
I. y>(4/3)x-(5/3)
Now use rise over run, or you could just look at the b. B is equal to the y-intercept. It can't be 0 or 9, and (-5/3) is equal to -1.67. So isn't that the closest to what the y intercept looks like in the graph?
