Answer:

1/a^19 (1 over a to the 19th power)

Step-by-step explanation:

when you divide, you subtract the exponents. -13 minus -6 is -19. when its a negative, you put it positive over 1. hope this helps :)

work:

a^-13/a^-6= a^-19

a^-19 --> 1/a^19

*****this is wrong, answer is 1/a^7

Answer:

  ∠N = 10°

Step-by-step explanation:

Assuming the marked point on segment LN is supposed to be the center of the circle, arc NML is 180°, so arc ML is 180° -160° = 20°.

Arc ML is intercepted by inscribed angle LNM, so the measure of that angle is half the arc measure:

  ∠N = (1/2)(20°) = 10°

Linda wants to buy 20 crayons. ToyWorld sells crayons at 4 for 25 cents, and GameLand sells crayons at 5 for 30 cents. Which of
Lemur [1.5K]

Answer: Game land sells 20 crayons for 5 cents less.

Step-by-step explanation:

Hi, to answer this question we have to calculate the price per crayon in each store, by dividing the amount paid in each case by the number of crayons that each store offers.

Toy world (T): 25/4 = 6.25 cents per crayon

Game land (G): 30/5 = 6 cents per crayon

Now, we have to multiply the cost per crayon by 20.

T=6.25 x 20 = 125 cents  

G=6 x 20 =120 cents

So, comparing both costs, Game land sells 20 crayons for 5 cents less.

125-120 = 5 cents

The diameter of a lake is 20 meters. I swim half way around the lake. How far did I swim?
MrRa [10]

Swimming half way around implies half of the circumference.

Circumference = pi x diameter

C = pi x 20

C = 20pi

20pi / 2 = 10pi

You swam 10pi meters = 31.42 meters.

Hope this helps!! :)
