Please find the area of this irregular shape

Genrish500 [490]

Answer: 10 sq units

Step-by-step explanation:

Area of triangle: 1/2 x b x h

1/2 x 2 x 2 = 2

Area of the left triangle is 2 sq units

1/2 x 4 x 2 = 4

Area of the right triangle is 4 sq units

Area of square: l x w

2 x 2 = 4

Area of square is 4 sq units

Area of figure: A of square + A of r tri. + A of left tri.

4 + 4 + 2 = 10

The area of the figure is 10 sq units.

Solve the following system of equations for x:

nikitadnepr [17]

Answer:

x=0.5

Step-by-step explanation:

2x+y= -2

and

4x+y= -8 so...

2x+y= -2 = 4x+y= -8

2x+4x= 6x

y+y=2y

-2+-8= -10

6x+2y= -10

2y- -10= 12

6x=12

6/12=0.5

x=0.5

The amount of force one exerts on a wrench handle to loosen a bolt is inversely

Inessa [10]

Answer:

$F = \frac{1152}{l}$

b) l=19.2 units

Step-by-step explanation:

a)Let F represent the force and l represents the length of the wrench handle.

Then inverse variation relation is:

$F\propto \: \frac{1}{l}$

When we introduce the variation constant, we get:

$F = \: \frac{k}{l}$

From the question when F=96, l=12

$96= \: \frac{k}{12}$

$k = 1152$

The equation is

$F = \: \frac{1152}{l}$

b) If a person can only exert 60 pounds of force on a wrench,then

$60 = \frac{1152}{l}$

$\implies \: l = \frac{1152}{60}$

$l = 19.2$

Hence the length of the wrench must be 19.2 units
