Answer 1
Answer: Ok so basically you square root the "Lengths " numbers at the top of the page. Using these answers ( the period/seconds numbers) you plot a graph
So, square root of 1.00 is 1

Square root of 1.96 is 1.4

Square root of 3.24 is 1.8

Square root of 4.00 is 2

Square root is 4.84 is 2.2

Square root of 6.25 is 2.5

Square root of 7.29 is 2.7

Square root of 7.84 is 2.8

Square root of 9.00 is 3

Then, you plot the numbers on the y axis. Also, did your teacher give you a specific graph to draw (such as a bar graph, column graph,line graph, etc?) because I'm not sure what graph you should draw. Hope this helps ;)

If Taryn and Alistair want to earn an additional $735 each , how many hours will each spend mowing lawns

Answers

If Taryn mowed 9 lawns in 7.5 hours and earned $112.50, then her hourly rate is:

$112.50 / 7.5 hrs = $15 per hour

If Alistair mowed 7 lawns in 5 hrs and earned $122.50, then her hourly rate is:

$122.50 / 5 hrs = $24.50 per hour

To earn an additional $735 each, they should work the following hours.

Taryn:  $735 / $15 = 49 hours

Alistain: $735 / $24.50 = 30 hours


Taryn and Alistair will each spend 49 hours mowing lawns to earn an additional $735 each.

To find out how many hours Taryn and Alistair will each spend mowing lawns to earn an additional $735 each, we need to divide $735 by their hourly rate. Let's assume their hourly rate is the same for both of them. If their hourly rate is $15, then dividing $735 by $15 gives us 49. Therefore, Taryn and Alistair will each spend 49 hours mowing lawns to earn an additional $735 each.

What is the algebraic expression for: four less than three times the number of egg orders and six more than two times the number of waffle orders

Answers

Answer:

In this problem

e represents egg orders

w represents waffles orders.

"Four less than three times the number of egg orders" is expressed

3e-4

"Six more than two times the number of waffle orders" is expressed

2w+6

Remember that "more" represent addition, "times" represent product

4-3x=o (o being egg orders)
2x+6=w (w being waffle orders) 

The sun of two number is 23. Their difference is 9. Write a system of equations to represent the situation. What are the two numbers?

Answers

Let one number be x
and second number be y
ATQ 
x + y = 23 ---> 1st equation
similarly, 
x - y = 9 ----> 2nd equation 
( adding y on both sides )
x = 9 + y -----> 3rd equation
Substituting 3rd equation in 1st equation or substituting value of x in 1st equation.
9 + y + y = 23 
( adding like terms on each side)
9 + 2y = 23
( subtracting 9 from both sides)
2y = 23 - 9
2y = 14
( Dividing 2 from both sides )
y = 7

Substituting value of Y in 1st equation
x + 7 = 23
( subtracting 7 from both sides )
x = 16

So, two numbers are 7 & 16 
or 
x = 16  & y = 7

Hope this helps you  :)
x+y=23
x-y=9
subtract the second from the first and you get 2y=14
Divide 2 from both side so y=7
and since x+7=23, x=16
so the final answer is x=16, y=7

What is 76.78 rounded to the nearest whole number?

Answers

Lets look at the number. 76.78. In each of the different place holders the number is higher than 5. Lets do some examples. 74 rounded to the nearest whole number is going to be 70. 76 rounded to the whole number will be 80. The .78 in your question also contributes. 

Answer: 80
When rounding to the "nearest whole number" you will need to either round up or down.
If its within 1 2 3 or 4 you round down, so if our number was 73, the nearest whole number would be 70.
Our question here consist of 76.78. 
Well just by looking at the first part of the number, 76, we already know that we are rounding up. so in doing this, I was able to get 80 because when 5 6 7 8 or 9 you round up.
