Find the area and the perimeter of the shaded regions below. Give your answer as a completely simplified exact value in terms of
____ [38]

Answer:

So we have a triangle and a semicircle.

If the triangle is equilateral, this is:

AB = BC = 6cm

Then the area of the triangle is equal to (base*height)/2

in this case:

A = (6*6)/2 = 36/2 = 18cm^2.

And the diameter of the semicircle is equal to 6cm, then the diameter is 3cm

And if the area of a circle is A = pi*r^2

then the area of half a circle is:

A = (pi/2*)3^2 = pi*4.5cm^2

Then, the area of the triangle plus the area of the semicircle is:

Total area = 18cm^2 +  pi*4.5^2

Rachel spent $38 for dinner. This was $10 less than 3 times what she spent for a movie. How much was the movie?
MatroZZZ [7]
So, first you subtract 10 from 38 which gives three times of the money spent for the movie. Then you divide 3 from it to give you the answer.

38-10 = 28
28/3 = 9.37 dollars

An article reports "sales have grown by 30% this year, to $200 million." What were sales before the growth? An article reports "
zimovet [89]

The amount of sales before growth according to the article is $153.85 million

<h3>How to find sales before growth?</h3>

let

  • Sales before growth = x
  • Percentage growth = 30%
  • New sales = $200 million

200 = x + (30% × x)

200 = x + (0.3 × x)

200 = x + 0.3x

200 = 1.3x

x = 200/1.3

x = 153.846153846153

Approximately,

x = $153.85 million
