Kazeer [188]

Answer:

y = $15.5x

Step-by-step explanation:

Given that

Tim earns $31 after 2 hours

$46.5 earns after 3 hours,

And, $62 earns after four hours

So first determine the each hour earnings i.e.

= $31 ÷ 2

= $15.5

In two hours it would be $31 and so on

So here the equation would be

y = $15.5x

Here

y = money amount

x = number of hours

What is P(2 or divisor of 9)?<br> please explain!

Dmitrij [34]

The probability that a divisor of 2 or 9 is chosen when the spinner is spun once is 2/3.

<h3>What is the probability?</h3>

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

P(2 or divisor of 9) = section that has a divisor of 2/ total number of sections + section that has a divisor of 2/ total number of sections

1/3 + 1/ 3 = 2/3

For the line segment whose endpoints are R(1, 2) and S(6, 7), find the y value for the point located 3 ov`er 4 the distance from

Mrac [35]

Answer:

23/4

Step-by-step explanation:

This means that it is 3/4 of the distance in the x <u>and</u> y coordinates, so it is 3/4 of the way from 2 to 7, and since this is a difference of 7-2=5, then it is 2 + (5 * 3/4) or 2 + 15/4 or 23/4.

Mrac [35]

Answer:

D) She has a total of $62 in the piggy bank.

Step-by-step explanation:

Jenny has been saving quarters in a piggy bank since she was born.

She decides to add 56 more quarters so that she can buy a $65 phone.

So she has 192 + 56 = 248 quarters currently.

1 quarter is equivalent to $0.25

248 quarters equals;

$\frac{248}{1}$ × $0.25 = $62

So Jenny has a total of $62 in the piggy bank.
