Can someone please answer this multiple choice question 29 , 30 , 32 please answer it correctly please show work please answer it correctly please please

29)  B

30)  A

32)  A

Step-by-step explanation:

29)  On the graph, it is shown that the line intersects directly with point (2,30)

The 2 represents hours worked, and the 30 represents total money earned

We can set these values equal to find Kelsey's pay per hour

2 hours = $30

Divide both sides of the equation by 2

1 hour = $15

Kelsey's hourly wage is $15 , or B

30)  Costas earns $67.50 per week

0.31 = Food

0.58 = Entertainment

He saves the rest

Find the exact values for food and entertainment

$67.50(0.31) = Food

$67.60(0.58) = Entertainment

$20.93 = Food

$39.21 = Entertainment

$67.50 - Food - Entertainment = Amount of money saved each week

$67.50 - $20.93 - $39.21 = $7.36

Out of the choices, $7.36 is closest to $7, so A is the answer to question #30

32)  13 girls + 12 boys = 25 total students

Janeen is represented as 1 of those students

Janeen out of 25 students = 1/25, or A

Hope this helps :)

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
