The diagram shows a square with a perimeter of 40cm. work out the percentage of the area inside the square that is shaded. the top side of the square is 7cm and the side is 4 cm

22.11%

Step-by-step explanation:

First, use the Pythagorean theorem to determine the length of , which in this case is . Then, find the remaining space by calculating the empty space.

On the left:

On the right:

Then,

Approximate decimal form is -77.89 (or 77.89)

Therefore, the shaded area is

The solution is in the following image

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

Here,

tip=18%of $32

tip=(18/100)*32

=0.18*32

=$5.76

Total payment=32+5.76=$37.76

Given height of gymnasium is 5/6 height of 30 foot ball

therefore height of gymnasium=5/6 * 30

=25 feet

Volume of rectangular prism=length * width * height

Given,

length=3/8cm

breadth=5/8cm

height=7/8cm

therefore volume=(3/8)*(5/8)*(7/8)

                           =105/512 cm3
