Which table shows y as DIRECTLY PROPORTIONAL to x

Mathematics

Furkat [3]3 years ago

Answer:

Table B

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

<em>Verify table B</em>

For x=1, y=1/2 -----> k=y/x=(1/2)/1=1/2

For x=2, y=1 -----> k=y/x=1/2

For x=3, y=3/2 -----> k=y/x=(3/2)/3=1/2

For x=4, y=2 -----> k=y/x=2/4=1/2

The values of k are the same

therefore

The table B shows y as DIRECTLY PROPORTIONAL to x

<em>Verify table D</em>

For x=1, y=3 -----> k=y/x=3/1=3

For x=2, y=5 -----> k=y/x=5/2=2.5

For x=3, y=7 -----> k=y/x=7/3

For x=4, y=9 -----> k=y/x=9/4

the values of k are different

therefore

The table D not shows y as DIRECTLY PROPORTIONAL to x

HELP FAST!! <br><br>solve for X
brilliants [131]

The sum of the inside angles of a 6 sides figure is 720

Add the known angles together:

90 + 112 + 131 + 154 + 118 = 605

Subtract the sum of the known angles from 720 for x:

x = 720 - 605 = 115

x = 115 degrees.

Answer:

2/5 hour is closest to 0 1/2 hours, 5/8 hour is closest to 1/2 hour. Therefore, the best estimate for the total time Maria spent with her sister is close to 1 hour

Step-by-step explanation:

We can represent the time Maria spends playing the game as 0.4, since 2/5 as a fraction is 0.4. This is closer to 1/2, which is 0.5 then it is to 0, because 4 is closer to 5 then 0. Then, we can represent the time Maria reads the book as 0.625, which is closer to 1/2 then it is to 1. Now we can add the estimated times. 1/2+1/2=1 hour
