Answer:

The number of tickets and cost have a proportional relationship.

Step-by-step explanation:

The points on the graph would be (2,36) , (5,90) , (9,162)

Graph the lines to see if the 'lines' are straight or not.

36/2 = 18

90/5 = 18

162/9 = 18

You can just this to check, as you can see, the rate of change stayed the same, so it is linear and proportional (straight line). Constant of proportionality means that between any 2 points on a line, they will have the same rate of change (aka. slope).

* * *

I don't want to confused anyone so I'll use this chance to explain the difference between linear and proportional.

In simple terms, proportional relationships has the y-intercept at 0. So proportional lines cross the origin (0,0) while linear lines just has to be a straight.

Hope I was able to help! Good Luck!

whats bigger 4/9 or 6/7

Answers

6/7 is greater than 4/9

Answer:

[tex]\frac{6}{7}[/tex]

Step-by-step explanation:

[tex]\frac{4}{9}or \frac{6}{7}[/tex]

First you need to find a common denominator. so you could just multiply 9 and 7 or you could write the factors of each number.9*7 is 63, so that is your denominator. Multiply top and bottom of [tex]\frac{4}{9}[/tex] by 7 and you should get [tex]\frac{28}{63}[/tex].Multiply top and bottom of [tex]\frac{6}{7}[/tex] by 9 and you should get [tex]\frac{54}{63}[/tex]. Is [tex]\frac{28}{63}[/tex] or [tex]\frac{54}{63}[/tex] bigger?[tex]\frac{54}{63}[/tex] is bigger so your answer would be [tex]\frac{6}{7}[/tex].

Stephano’s marble will get there first because the slope for Stephanos’s marble is y=2.25x, and when you do the math, (6=2.25x), the marble will reach 6 ft. at 2.7 seconds, and the x in y=3/2x for Pete’s marble is 6 ft. after 4 seconds, so Stephano’s marble will reach the 6 ft. mark first.

The winning candidate in an election receives 0.58 of the votes. There are 1000 voters. How many votes does the winning candidate receive?

Answers

They receive 580 of the votes because 58% of 100 is 580 or just simply multiply 0.58*1000=580.

The winning candidate in an election receives 0.58 of the votes. There are 1000 voters. The winning candidate receives the votes is 580.

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

The winning candidate in an election receives 0.58 of the votes.

There are 1000 voters.

58% of 1000

= 0.58 x 1000

= 580
