Step-by-step explanation:

It takes 12 men 5 days to complete a job. Work out how many days it would take 3 men to complete the same job.

12 * 5 = 60

60/3 = 20

It will take 3 men 20 days to do the same job

Answer:

\frac{9}{2}\pi +35

Step-by-step explanation:

The area of trapezoid is given by the formula:

A=\frac{1}{2}(b_1+b_2)h

Where

A is the area

b_1 is base 1

b_2 is base 2, and

h is the height

Looking at the figure, base 1 is the left line which goes from y = 3 to y = 3, so 6 units. Also, base 2 is the right line which goes from y = -3 to y =5, so 8 units.

The height is the horizontal distance in the middle, which goes from x = -2 to x = 3, so 5 units. Hence area of trapezoid is:

A=\frac{1}{2}(b_1+b_2)h\\A=\frac{1}{2}(6+8)*5\\A=35

Now, area of semicircle is:

A=\frac{\pi r^2}{2}

Where

A is the area

r is the radius

Looking at the figure, the diameter (twice radius) goes from y = -3 to y = 3, so 6 units. But radius is half of that, so 3 units. Hence area of semicircle is:

A=\frac{\pi r^2}{2}\\A=\frac{\pi (3)^2}{2}\\A=\frac{9}{2} \pi

Total area of the figure is \frac{9}{2}\pi +35

Raise 8 to the 5th power, then subtract the result from h. What would the expression be?
lawyer [7]
The equation would look like this:

h - 8⁵

To solve for the value of h.
It must be in standard form, where one side is equal to 0.

h - 8⁵ = 0
h = 8⁵
h = 8 x 8 x 8 x 8 x 8
h = 32,768

T
he exponent above the number indicates the number of time its base will be multiplied by itself. In this case, the base will be multiplied 5 times.

To check: h = 32,768
h - 8⁵ = 0
32,768 - 32,768 = 0
0=0
