Sara earned $7.25 per hour plus an additional $105 in tips waiting tables last week. She earned at least $329.75. If h

jonny [76]

Answer:

The minimum number of hours that Sara could have worked is 31 hours .

The inequality representation of possible value of h is 105 + 7.25 h $\geq$ 329.75

Step-by-step explanation:

Given as :

The earning of Sara in per hour amount = $7.25 per hour

The additional earning of Sara as tips = $105

The Total earning of Sara = $329.75

Let The minimum number of hours that Sara could have worked = h hours

<u>Now, According to question</u>

The Total earning of Sara = The earning of Sara in per hour amount × minimum working hours + The additional earning of Sara as tips

I.e $329.75 = $7.25 per hour × h + $105

Or, $105 + $7.25 per hour × h = $329.75

Or, $7.25 per hour × h = $329.75 - $105

Or, 7.25 per hour × h = 224.75

∴ h = $\dfrac{224.75}{7.25}$

I,e h = 31 hours

So, The number of hours Sara worked = h = 31 hours . Answer

Hence, The minimum number of hours that Sara could have worked is 31 hours .

The inequality representation of possible value of h is 105 + 7.25 h $\geq$ $329.75

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 8 inches.

11111nata11111 [884]

Answer: PART A.

y= remaining height of candle

x= rate the candle burns down in inches per hour

8= original height of candle

the function would be y=8- 0.5x because the candle starts at a height of 8 feet and loses half an inch per hour.

You can use this function to create ordered pairs by putting in number at x which indicates the time:

x=1

y=8- (.5×1)= 7.5

(1, 7.5)

you can then do this for other numbers and get:

(2, 7.0) (3, 6.5) (4, 6.0) (5, 5.5) (6, 5.0)

PART B.

This equation is a function because all of the x-values had different y-values as seen in the coordinates (1, 7.5) (2, 7.0) (3, 6.5) (4, 6.0) (5, 5.5) (6, 5.0)

PART C.

If the rate was 0.4 inches an hour, it would still be a function because the rate is the only thing that changed making the new function y= 8- 0.4x.This equation would make coordinates of (0,8) (1, 7.6) (2, 7.2) (3, 6.8) and so on with each x value creating a different y value.

Step-by-step explanation: hope this helps

What two whole numbers is 29−−√ between?: 3 and 4 4 and 5 5 and 6 6 and 7

jolli1 [7]

The two whole numbers are 5 and 6 ⇒ 3rd answer

Step-by-step explanation:

To prove that a square root number lies between which two consecutive integers do that

Find a square number less than the number under the root
Find a square number greater than the number under the root
Find the square root of the square numbers, they will be the two integers that the root lies between them

∵ The number is $\sqrt{29}$

- Find a square number less than 29

∵ 25 is a square number

∵ 25 is less than 29

- Find a square number greater than 29

∵ 36 is a square number

∵ 36 is greater than 29

∴ 25 < 29 < 36

- Take √ for each number

∴ $\sqrt{25}$ < $\sqrt{29}$ < $\sqrt{36}$

∵ $\sqrt{25}$ = 5

∵ $\sqrt{36}$ = 6

∴ 5 < $\sqrt{29}$ < 6

The two whole numbers are 5 and 6
