Answer: Total weekly cost was $230.4.

Step-by-step explanation:

Since we have given that

Number of hours Sue worked on Monday = 6\frac{3}{4}=\frac{27}{8}\ hours

Number of hours Sue worked on Tuesday = 4 hours

Number of hours Sue worked on Wednesday = 7\frac{3}{4}=\frac{31}{8}\ hours

Number of hours Sue worked on Thursday = 8 hours

Number of hours Sue worked on Friday = 5\frac{1}{2}=\frac{11}{2}\ hours

So, Total number of hours in all five days is given by

\frac{27}{4}+4+\frac{31}{4}+8+\frac{11}{2}\\\\=12+\frac{27+31}{4}+\frac{11}{2}\\\\=12+\frac{58}{4}+\frac{11}{2}\\\\=12+\frac{58+22}{4}\\\\=12+\frac{80}{4}\\\\=12+20\\\\=32

Cost of her wage per hour = $7.20

Total  weekly wage is given by

32\times 7.20\\\\=\$230.4

Hence, Total weekly cost was $230.4.

Please help me with those question please help with out number 1

Answer:

1) For each value of x, a value of y is increased by 5.

x = 0, y = 5

x = 1, y = 10

x = 2, y = 15

x = 3, y = 20

------------------------------------------------------------------------------------------

2) For each two values of x, a value of y is increased by 10.

x = 0, y = -2

x = 2, y = 8

x = 4, y = 18

x = 6, y = 28

-------------------------------------------------------------------------------------------

3)

x = 0, y = 1

x = 1, y = \frac{7}{5}

x = 5, y = 3

x = 10, y = 5

-------------------------------------------------------------------------------------------------

4)

x = 0, y = 2

x = 1, y = 17

x = 2, y = 32

x = 5, y = 77

Step-by-step explanation:

This is as easy as replacing x for the actual value show on the table.

1)

y=5x+5

When x = 0, y = ?

y=5(0)+5\\y=0+5\\y=5

When x = 1, y = ?

y=5(1)+5\\y=5+5\\y=10

When x = 2, y = ?

y=5(2)+5\\y=10+5\\y=15

When x = 3, y = ?

y=5(3)+5\\y=15+5\\y=20

-------------------------------------------------------------------------------------------------------

2)

y=5x-2

When x = 0, y = ?

y=5(0)-2\\y=0-2\\y=-2

When x = 2, y = ?

y=5(2)-2\\y=10-2\\y=8

When x = 4, y = ?

y=5(4)-2\\y=20-2\\y=18

When x = 6, y = ?

y=5(6)-2\\y=30-2\\y=28

----------------------------------------------------------------------------------------------------

3)

y=\frac{2}{5}x +1

When x = 0, y = ?

y=\frac{2}{5}(0) +1

y=0 +1\\y=1

When x = 1, y = ?

y=\frac{2}{5}(1) +1\\y=\frac{2}{5} +1

y=\frac{2}{5}+1(\frac{5}{5})\\ y=\frac{2}{5}+\frac{5}{5}  \\y=\frac{7}{5}

When x = 5, y = ?

y=\frac{2}{5}(5) +1\\y=2+1\\y=3

When x = 10, y = ?

y=\frac{2}{5}(10) +1\\y=2(2) +1\\y=4+1\\y=5

-------------------------------------------------------------------------------------------------

4)

y=15x+2

When x = 0, y = ?

y=15(0)+2\\y=0+2\\y=2

When x = 1, y = ?

y=15(1)+2\\y=15+2\\y=17

When x = 2, y = ?

y=15(2)+2\\y=30+2\\y=32

When x = 5, y = ?

y=15(5)+2\\y=75+2\\y=77

Elza [17]

Answer:

x=20

Step-by-step explanation:

just use the pythagorean theorem!!

square 12 and 16 to get 144 and 256

add those together to get 400, and then just take the square root of 400 (which is 20)

this means that x=20!

hope this helps!! :)
