Answer:

c. 56 in.

Step-by-step explanation:

use pythagorean theorem (a^{2} +b^{2}  = c^{2} ) where a, b, and c are the lengths of the side of a right triangle. c is the length of the longest side across from the right angle of the triangle (the diagonal). To find the length of the TV a=\sqrt{20^{2} -12^{2}. Now that you have the length you simply must add the length of each side of the TV. Perimeter = sum of the lengths of every side. TV has 4 sides length is 16 and width is 12. So, 16 + 16 + 12 + 12 = 56 in

Allushta [10]

Answer:

So I assume we are figuring out the number of men and women here, so:

m + 2w = 12

m = 12 - 2w

12 - 2w + 3w = 22

w = 10

m + 2w = 12

m + 2(10) = 12

m + 20 = 12

m = -8

Robert bought $1.60 worth of stamps with 20 coins all in nickels and dimes. how many nickels and dimes did he use?
mrs_skeptik [129]
Nickels are 5 cents, and dimes are 10 cents.
(By luck..) eventually you can have 12 dimes, meaning you have 120 cents, or $1.20 ... 20-12=8.. meaning you used 12 dimes and are missing 8 more coins. which means you can have 8 nickels which is 40 cents. 120+40=160 cents or $1.60
Hope this helped.

Tpy6a [65]

Answer:

65.54% (nearest hundredth)

Step-by-step explanation:

Given:

  • \sf \mu=9000
  • \sf \sigma=1000

\sf X \sim N(\mu, \sigma^2)\implies X \sim N(9000,1000^2)

P(X > 8600) = 1 - P(X ≤ 8600)

                    = 1 - 0.3445782584

                    = 0.6554217416

                    = 65.54%
