Answer:

The area of the shaded region is the quarter circle minus the isosceles right triangle. The area of quarter-circle is pi*r^2/4=pi*8^2/4=16pi. The area of triangle is 8*8/2=32, so the area is 16pi-32.

The perimeter of the shaded region is the length of arc plus the segment. The length of arc is pi*2r/4=pi*16/4=4pi, and the length of the segment is 8*\sqrt(2) according to pythagorean's theorem. The total perimeter is 4pi+8*\sqrt(2).

Step-by-step explanation:

Which two days had a ratio of 2:5 computers sold? Looking for brainliest.
Marianna [84]

Answer:  A. Wed to Fri

We have a bunch of natural numbers and we're told a pair is in the ratio 2:5.

For natural numbers to have this ratio, the left number will be a multiple of two and the right number will be a multiple of five.

Our only option for a multiple of 5 is 15, Friday.  So we have

2:5 = x:15

and x = 15*2/5 = 6

which was Wednesday's number.  So we get Wed:Fri=6:15=2:5.

Is 300 mm greater than 3 cm
rewona [7]

Answer:

Yes

Step-by-step explanation:

There are 10 mm in 1 cm.

We have 300 mm, so let's convert this to cm by using a proportion:

\frac{10mm}{1cm} =\frac{300mm}{x} , where x is the number of cm in 300 mm.

Cross-multiplying, we get: 10x = 300, so x = 30 cm.

Clearly, 30 cm > 3 cm, so yes, 300 mm is greater than 3 cm.

Hope this helps!

Which expressions is equivalent ?
agasfer [191]
<h3>3 Answers: Choice C, Choice D, Choice F</h3>

What these expressions have in common is that their exponents multiply to 16

  • (-4)*(-4) = 16 for choice C
  • (-2)*(-8) = 16 for choice D
  • 8*2 = 16 for choice F

The rule used here is (a^b)^c = a^(b*c). We multiply the exponents and keep the base the same.
