A proportional relationship will always go through the origin so you can eliminate the first two. In the last one the second coordinate is (4,12) which is wrong because the x is 12 and the y is 4. So that is how you know the 3rd option is correct :)

Step-by-step explanation:

Given ratio,

→ 9:13

The 5 equivalent ratios are,

→ (9 × 2):(13 × 2) = 18:26

→ (9 × 3):(13 × 3) = 27:39

→ (9 × 4):(13 × 4) = 36:52

Probabilities can be expressed as a ratio of the total who fit the criteria and the total who do or do not. In other words, true/total. Here, there are 9 who wear green and 26 who do not. So, the probability is 9/26.

Because the question is asking about the number of female wearing green shirts, the total number of female, 26, will be in the denominator and the total number of females in green shirts, 9, will be in the numerator, so the answer will be 9/26

If x and y are in direct proportion and y is 80 when x is 10, find y when xx is 15.

Answers

Answer:

y = 120

Step-by-step explanation:

If x = y, they can be written as a fraction to show their proportionality as [tex]\frac{10}{80}[/tex]. This is equal to [tex]\frac{1}{8}[/tex], so when x = 1, y = 8. To find when y is equal to x when x = 15, just multiply y by 15. 15(8) = 120, so y = 120 when x = 15.

Answer:

120

Step-by-step explanation:

set up a proportion: 80/10=y/15

solve: 80*15=10y

1200=10y

y=120

The speed limit on an interstate highway is 65 miles per hour.

Which cars are driving at or below the speed limit?

Answers

Answer:

There are 5,280 feet in a mile.

There are 60 minutes in an hour.

As a quick check, does this answer look correct? If you were travelling 5 miles per hour slower, at a steady 60 mph, you would be driving 60 miles every 60 minutes, or a mile a minute. If you're driving 65 miles per hour, then, you ought to be going just over a mile a minute — specifically, 1 mile and 440 feet.

While it's common knowledge that an hour contains 60 minutes.

Step-by-step explanation:

If your car is traveling 65 miles per hour, then it is also going 343,200 feet (65 × 5,280 = 343,200) per hour. Then, you can divide the total feet per hour by 60, and you know that your car is traveling 5,720 feet per minute.

Which is an equation of a direct proportion?

Answers

The correct answer is y = -2x.

Direct proportion can also be known as Direct variation. When the ratio of two quantities equals constant, we call it Direct Proportion. Direct Proportion is denoted by  [tex]\alpha[/tex] .  

Let us consider two quantities a and b, then the direct proportion between a and b can be expressed as,

                                          a  [tex]\alpha[/tex]  b

                                 =>    [tex]a/b = k[/tex] ( where k is constant)

                                 =>     [tex]a = kb[/tex] [tex]--- >[/tex] 1

Substitute a=x and b=y in 1, and then we get

                                          [tex]x = ky[/tex]

Therefore, the general form of an equation which satisfies direct proportion is x = ky.

[tex]y=1/2x-2, y=-2x+3,y=4/x[/tex]  are not in the form of [tex]x = ky[/tex].

So, The equation of direct proportion is y = -2x.
