It’s for question 4
Answers
Answer:
$6,000
Step-by-step explanation:
We have to start by finding the conversation rate.
So, we can divide 9,600 by 8 to find how much the ratio is being multiplied by.
9,600 / 8 = 1200
Now that we know the conversion rate, we can multiply by five to find how much the expenses really cost, according to the ratio.
1200 * 5 = 6000
Their expenses this month are 6000

Baldwin made a scale drawing of the town library. He used the scale 1 centimeter : 9 meters. The parking lot is 9 centimeters in the drawing. How long is the actual parking lot?
Answers
Answer:
81m
Step-by-step explanation:
1/9 = 9/x
x = 81
Because the ratio is 1:9 if you wanna change the centimeters you have to do it on both sides
So what times 1 equals 9? 9
So multiply the meters by 9.

30 in length 24inches width
Step-by-step explanation:
Multiply the multiples if 5 and 4 together until you reach 720.
5*4=20
10*8=80
15*12=180

Your length is 30 in and your width is 24in.
Does the table represent an exponential function? Explain.
A. Yes, the x-values decrease by a constant amount and the y-values are multiplied by a constant amount.
B. No, the x- and y-values show a quadratic relationship only.
C. Yes, the x-values increase by a constant amount and the y-values are multiplied by a constant amount.
D. Yes, the y-values increase by a constant amount and the x-values are multiplied by a constant amount.
Answers
Answer:
No, because as the x-values are increasing by a constant amount, the y-values are not being multiplied by a constant amount.
Step-by-step explanation:
We have a set of ordered pairs of the form (x, y)
If a function is exponential then the ratio between the consecutive values of y, is always equal to a constant.
This means that:
\frac{y_2}{y_1}=\frac{y_3}{y_2}=\frac{y_4}{y_3}=by1y2=y2y3=y3y4=b
This is: y_2=by_1y2=by1
Now we have this set of points {(-1, -5), (0, -3), (1, -1), (2, 1)}
Observe that:
\begin{gathered}\frac{y_2}{y_1}=\frac{-3}{-5}=\frac{3}{5}\\\\\frac{y_3}{y_2}=\frac{-1}{-3}=\frac{1}{3}\\\\\frac{3}{5}\neq \frac{1}{3}\end{gathered}y1y2=−5−3=53y2y3=−3−1=3153=31
Then the values of y are not multiplied by a constant amount "b"

If a quantity is decreased by x% the new value of that quantity is (100 -x)% of the old one.The value of original number nearest to tenth is 55.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
To convert percentage into a fraction it is divided by 100.
Given that,
The percentage of decrease = 8.3%
The number obtained after decrease = 50
Since the number obtained after decrease is the original number minus the decrement in the number by 8.3%.
Thus, the expression for original number N is given by,
N - 8.3% of N = 50
=> N - (8.3 / 100) × N = 50
=> (91.7 / 100) × N = 50
=> N = 50 × (100 / 91.7)
=> N = 54.52
Nearest to tenth its value is 55.
Hence, the original number nearest to tenth is 55.

An author receives $0.75 for each hardcover book or paperback book that is sold. There were x hardcover books and 42,000 paperback books sold of her most recent book. The author received a total of $60,000 for the book sales. The equation below can be used to determine the number of hardcover books that were sold. 0.75(x + 42,000) = 60,000. How many hardcover books were sold?
Answers
0.75x + 31,500 = 60,000
Subtract both sides by 31,500
0.75x = 28500
Divide both sides by 0.75

Answers
Answer:
12/15 or .8
Step-by-step explanation:
So first you divide both the numerator and denominator by 2 because it’s the biggest number that goes into both 24 and 30
24 and 30 simplified by 2 gives us 12 and 15
you can’t simplify any further so your answer is 12/15
If you want a decimal, then you divide 24 by 30 and your answer is .8
