What is the product?

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

Answer:

45 ∘,45 ∘ ,90 ∘

Step-by-step explanation:

Since, the angle is right angled isosceles triangle. One of the angles will be 90 ∘

. let the other two angles be x

Thus, sum of angles = 180

90+x+x=180

2x=90

x = 45 ∘

The measure of each angle is: 45 ∘ ,45 ∘ ,90 ∘

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

→ (9 × 5):(13 × 5) = 45:65

→ (9 × 6):(13 × 6) = 54:78

Hence, these are the ratios.

Step-by-step explanation:

6+8= 14

6/14×100=3/7×100=300/7=42.85

8/14×10=4/7×100=400/7=57.14

Answer:

0.75

Step-by-step explanation:

in a unit rate the denominator is always 1. So, to find unit rate divide the denominator with the numerator in a way that the denominator becomes 1.

Answer:

$8

Answer:

Marc: 8 meters & 4 seconds

Prisha: 6 meters & 3 seconds

Step-by-step explanation:

Marc: If Marc travels 8 meters in 4 seconds it means that he has a speed of 2m/s

Prisha: If Prisha travels 6 meters in 3 seconds it means that she has a speed of 2m/s

To find speed we simply have to divide distance by time

The way that I figure out the answer was by trial and error. This is when we have to get random numbers and try them.

2 seemed a reasonable answer as it couldn't a number such as 5 as there is only 1 factor of 5 between 0 and 9. There are 4 factors of 2 between 0 and 9

Hope this helps, have a great day!!

Answer:

B straight lines that pass through the origin.

Step-by-step explanation:

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.

Step-by-step explanation:

A line beginning at point (0,0) and continuing to (30,10)

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 :)

Answer: 10% of 900 is 90

Step-by-step explanation: 900/10 is 90

Hope this helps:)

Answer:

Step-by-step explanation:

Solve 10% of 900?

10% = 1/10

so

900 : 10 = 90

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.
