Answer:

a) n (A) = 7

Step-by-step explanation:

Here, set A = {2,5,7,9,13, 25, 26)

Noe, for any set A,

Party favors are on sale for $2.50 each. You have $380 to spend on the decorations and gifts, and you have already spent $272 on

Alenkinab [10]

Answer:

we could buy 43 party favors

Step-by-step explanation:

initially we have an amount of $380

if we already spend an amount of $272 this we have to subtract it from the total

$380 - $272 = $108

if each party favor comes out $ 2.50 and we have $ 108 we have to divide what we have by what each one comes out to know how many we can buy

$108 / $2.50 = 43.2

this means we could buy 43 party favors

I need help anybody ?

nasty-shy [4]

Answer and Step-by-step explanation:

Simply use the Pythagorean Theorem to solve.

The Pythagorean Theorem is used to solve for a side in right triangles.

$A^{2} +B^{2}= C^{2}$

Plug the sides values into the equation.

$A^{2} + 13^2 = 20^2\\\\A^2 + 169 = 400\\\\A^2 = 231\\\\A = 15.1987$ <- This is the answer.
