A persons weekly wage is worked out by using the formula
LuckyWell [14K]
The formula is : #of overtime hours(h) *£16 + basic pay (b)
So, the easier way to put it is W=h*16+b

A: Wage= £284

A. W=h(9)*16+b(140)
=9*16+140
=144+140
=284

B: Overtime = 11
So, with this one, we work backwards
Using the same formula

W=h*16+b
We can fill in
300=16h+124

First, subtract 124 on both sides leaving

176=16h
Now we divide 16 on both sides, canceling out the right side
Leaving
11=h

2/5x - 15 = 5/8x - 16​
Anton [14]

Answer:

x=40/9

Step-by-step explanation:

(2/5)*x-((5/8)*x)-15+16=0

(2/5)*x+(-5/8)*x-15+16=0

1-9/40*x=0 // -1

-9/40*x=-1// : -9/40

x= -1/(-9/40)

x=40/9

x=40/9

What is the area of the figure?? HELP PLS!!
Alchen [17]
Hi!

I've included an image showing the shape divided into 3 rectangles. We're going to find the area of each rectangle.

To find the area of a rectangle, multiply the length times the width. 

The red rectangle:

8 · 9 = 72
The area of the red rectangle is 72in.

The orange rectangles:

The orange rectangles have the same area. 
10 · 3 = 30
30 + 30 = 60
The area of both orange rectangles is 60in.

72 + 60 = 132

The answer is 132 square inches.

Hope this helps! :)

If rectangle ABCD was reflected over the y-axis, reflected over the x-axis, and rotated 180º, where would point A' lie? (1, -1)
kodGreya [7K]

Answer:

Point A reamains unchanged.

Step-by-step explanation:

Let

A(1, -1)

B(1, 1)

C(-4, -1)

D (-4, 1)

REFLECTED OVER Y-AXIS:

When we reflected over Y-AXIS we have to change the sign of X-Coordinates of all vertices so, above given vertices becomes

A(-1, -1)

B(-1, 1)

C(4, -1)

D (4, 1)

REFLECTED OVER X-AXIS:

When we reflected over X-AXIS we have to change the sign of Y-Coordinates of all vertices so, above given vertices becomes

A(-1, 1)

B(-1, -1)

C(4, 1)

D (4,-1)

When we rotated over 180 degree than we have to change the signs of both coordinates of all vertices

A(1, -1)

B(1, 1)

C(-4, -1)

D (-4,1)

we can see that after the opertion of all three processes i.e  reflected over the y-axis, reflected over the x-axis, and rotated 180ºrespectively vertices are same as original vertices so, Rectangle remain unchanged. and point A is also unchanged
