A _____________ ratio in any proportional relationship.
Answer:
a proportional relationship is look at the different values that the variables take on when one variable is one value, and then what is the And then take the ratio between them. and you see y to x, or y divided by x-- the ratio of y to x
If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
We have to get ratio of the two quantities for all the given values. If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.
Writing an Equation to Represent a Proportional Relationship. An expression of equality of ratios is called a proportion. The proportion expressing the equality of the ratios A:B and C:D is written A:B = C:D or A:B::C:D. A is to B as C is to D.

13) A football team completed three passes for 18 yards each and two runs for 12 yards each, but was also assessed four penalties which cost them 5 yards each. Write a numerical expression which would determine how many yards they have gained or lost.
Answer
18(2)+12(2)-4(5)
36+24-20
60-20
40
Step-by-step explanation:
since they had two-18 yard passes and two 12 yard runs, that's the first part of the expression, and then they had four penalties that cost them 5 yards, and that was the last term. When you simplify, you end up with 40 yards gained.
In math
Passes: 18(2)
Runs: 12(2)
Penalties:4(5)
equation
18(2)*12(2)-4(5)

(-15,-6), (8,3) Find the slope of the line through each pair of points?
Slope is equal to the change in
y
over the change in
x
, or rise over run.
m = change in y / change in x
The change in
x
is equal to the difference in x-coordinates (also called run), and the change in
y
is equal to the difference in y-coordinates (also called rise).
m = y^2 - y^1 / x^2 x^1
Substitute in the values of

The selling price of the book will be equal to $12.74.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that Sophie had a 15% off coupon for the book store. The original price of the book she bought was $14.99.
The selling price will be calculated as,
Selling price = 14.99 x ( 100 - 15)%
Selling price = 14.99 x ( 85 / 100 )
Selling price = 14.99 x 0.85
Selling price = $12.74

A hotel has a total of 172 rooms. About 58% of the hotel rooms have 2 queen beds in each room and the rest of the rooms have 1 king bed. How many rooms have queen beds?
Answer:
99.76 = 100

Queen rooms: 99.76 but since it is a real world problem round it to the nearest tenth
king rooms: 72

172 x 58% or 172 x 0.58= 99.67.
rounded = 100.00
172 - 100 = 72

BRAINLIEST INCLUDED!!!! Elena went to a sporting goods store that was having a sale. She bought a tennis racket and 3 cans of tennis balls. The tennis racket normally costs $43. All tennis rackets are marked down 15%. One can of tennis balls normally costs $4. The tennis balls are not marked down. The sales tax rate is 8.5% How much will she pay for everything, including tax?
Answer:
She will pay $52.68, including taxes
Step-by-step explanation:
One can of tennis ball is $4 and there are no discount on it. Elena bought 3 cans, so:
can = 3 x 4 = 12
One tennis racket is $43 but it has a discount of 15%:
discount = 0.15 x 43 = 6.45
total racket = 43 - 6.45 = 36.55
Elena will have to pay:
pay = 12 + 36.55 = 48.55
She will also have to pay taxes, which are 8.5% over the price she paid:
pay + tax = 48.55 x 0.085 = 4.13
total to pay = 48.55 + 4.13 = 52.68
Buying 3 can of tennins ball and one racket, Elena paid $52.68, including taxes.
