The equation representing the given situation is <u>10.75h - 13.00 = 100.75</u>.

In the question, we are given that Jada has time on the weekends to earn some money. A local bookstore is looking for someone to help sort books and will pay $10.75 an hour. To get to and from the bookstore on a work day, however, Jada would have to spend $6.50 on bus fare.

We are asked to write an equation to represent the situation of a day when Jada takes home $100.75 after working h hours and after paying the bus fare.

The time Jada works for = h hours.

The per-hour rate = $10.75.

Thus, the amount Jada earns after working for h hours = $10.75h.

Jada's bus fare to and from the bookstore = $6.50.

Since a weekend has two days, he will be visiting the store twice a week, thus we will take two times the bus fare, that is, $6.50*2 = $13.00.

Thus, Jada's total earnings on the day after working for h hours and paying the bus fare = $(10.75h - 13.00).

But, we are given that Jada takes home $100.75 after working h hours and after paying the bus fare.

Thus, equating the two quantities, we get the equation as:

10.75h - 13.00 = 100.75.

Thus, the equation representing the given situation is <u>10.75h - 13.00 = 100.75</u>.

50 points. Only solve 6-10. And show work
sineoko [7]

Answer :

6 : Margaret has 30 50-cent coins and 26 10-cent coins

let 'x' represent the number of 50-cent coins, then '56-x' represents the number of 10-cent coins

17.60 = 0.5x + 0.1(56-x)

solving for 'x' we have x=30

56-30 = 26

7 : Total money = $29.40

mich money = m dollar,

amy money = (3/4)m dollars,

Total = m + 3m/4 = 29.40,

4m+3m = 4*29.4,

7m = 117.6,

m = 117.6/7 = 16.8

Hence,

 Michelle's money = $16.80

Amy money = $12.60    

8 : (a) The amount of milk in a carton is normally distributed with a mean of 260 millilitres (mL) and a standard deviation of 8 mL. Every milk carton is labelled with the serving size as 250 mL. (i) What is the probability that a randomly selected carton has more than the labelled serving? [3 marks) (ii) Determine the amount of milk in a carton for which only 7.08% of cartons fall below this amount. [3 marks (iii) Find an interval around the mean y = 260mL such that 95% of all milk cartons fall within this interval. (5 marks)

9 : a=3, b=5

So b+2 = a+4 = 4a-b

b=a+2

3a=b+4

b=2a-1

Hence

2a-1=a+2

10 : original dimensions of rectangle, length = 18cm and width = 10cm  

Let length and width = L and W.

from statement "A rectangle has perimeter 56 cm. If 4 cm is taken from the length and added to the width, the rectangle becomes a square", you can deduce

2L + 2W = 56 ( its sides make up its perimeter )

L - 4 = W + 4

L = W + 8

sub L = W + 8 into 2L + 2W = 56

2 ( W + 8 ) + 2W = 56

2W + 16 + 2W = 56

4W = 40

W = 10

sub W = 10 into L = W + 8

L = 10 + 8 = 18

Which point on the number line best represents√57?
Cerrena [4.2K]

Answer:

8.

Step-by-step explanation:

\sqrt{57} =\sqrt{3 * 19}

Since this cannot be further simplified, we will calculate the square root of 57 with our calculators.

We find that the square root of 57 is 7.549834435, and since the tenths place is a 5, we will round up to the next whole number. So, the point on the number line that best represents the square root of 57 is 8.

Hope this helps!
