Answer:

105 shifts

Step-by-step explanation:

Hourly net rate of pay = $12

1 shift = 8 hours

⇒ net pay per shift = $12 × 8 = $96

Total cost  = tuition + residence + books

                  = $4500 + $4800 + $700

                  = $10,000

To calculate how many shifts Joanne needs to work, divide the total cost by the pay per shift and round it up:

Number of shifts = total cost ÷ net pay per shift

                            = $10,000 ÷ $96

                            = 104.1666666...

                            = 105 shifts

Note: we need to round up, as if Joanne works 104 shifts, she will earn $9,984 which is not quite enough to pay for tuition, residence and books.

i THINK THE ANSWER IS b

what is the next two term in the sequence 6, 10, 14, 16

Answers

Answer:

Next two terms of the sequence is 20 and 24.

Step-by-step explanation:

The arithmetic sequence is 6, 10, 14 , 16

First term (a) = 6

Subtract the first term from the second term:

10 - 6 = 4

Subtract the second term form the third term:

14 - 10 = 4

Subtract the third term from the Fourth term:

16 - 14 = 4

Here, You will notice that each time you move from one number to the next one it increases by four. So, the difference between one and the next term is four.

So,

Next two terms are:

16 + 4 = 20

20 + 4 = 24

Hence,

Next two terms of the sequence is 20 and 24.

Step-by-step explanation:

Given Sequence :- 6 , 10 , 14 , 16

To find :- Next 2 terms in the sequence

Solution :-

D( common difference ) = a2 - a1

D = 10 – 6

D = 4

Next two terms ,

16 + D ; 16 + 4 = 20

20 + D ; 20 + 4 = 24

The triangle it self (using SSS) is 54 square feet
The rectangle is 180 sq ft
Add them up and it’s 234 :]

Answer:

215.7176 ft^2

Step-by-step explanation:

One step at a time.

First, let's figure out what the square area is.

12 ft by 15 ft = A=wl=15·12=180 ft^2

Now we add the tringle area: K = 35.7176 ft2

Add: 215.7176 ft^2

Sides:

a = 12 ft

b = 7.93725 ft

c = 9 ft

Other:

P = 28.9373 ft

s = 14.4686 ft

K = 35.7176 ft2

r = 2.46863 ft

R = 6 ft

Agenda:

A = angle A

B = angle B

C = angle C

a = side a

b = side b

c = side c

P = perimeter

s = semi-perimeter

K = area

The two angles form a straight line of 180 degrees.

This means they add to 180

115 + (4n-5) = 180

4n+110 = 180

4n = 180-110

4n = 70

n = 70/4

n = (35*2)/(2*2)

n = 35/2 is the answer as a fraction
