Answer: 72° or any muliple of it: 72°, 144°, 216°, 288°, 360°, ...

It can be either clockwise or counterclockwise.


Explanation:


Thi is because a regular pentagon has 5 congruent sides.

Then you determine the angle of rotation by dividing 360° (a complete turn) by the number of sides (5)

360° / 5 = 72°.

Then every 72° the segments of the image will overlap those of the preimage.

Answer:

  • 80 tons
  • $20,000

Step-by-step explanation:

<u>21. 1st scenario</u>

  • B = fy + wz
  • 100,000 = 15,000*4 + 500w
  • 500w = 100,000 - 60,000
  • 500w = 40,000
  • w = 40,000/500
  • w = 80

80 tons of wheat

<u>22. 2nd scenario</u>

  • B = fy + wz
  • 50,000 = 2y + 200*50
  • 50,000 = 2y + 10,000
  • 2y = 50,000 - 10,000
  • 2y = 40,000
  • y = 20,000

Given that G=ab find the percentage increase in G when both a and b<br> increase by 10%
monitta

The percentage change in G is 21 %

<h3>What is Percentage change ?</h3>

Percentage change is defined as the increase or decrease in the value as compared to the original value multiplied by 100.

It is given that

G = ab

when a is increased by 10% the new a will be = 1.1 a

When b is increased by 10% the new b will be 1.1 b

So,

G' = 1.1a *1.1 b

G' = 1.21 ab

G' = 1.21

(G' - G)*100/G = (1.21-1)*100/1

The percentage change is 21 %
