Answer:

(1/9)

Step-by-step explanation:

Mary can choose from white,red,or pink construction paper to create a heart.

And she can use black, blue or green marker to write out her message and she can’t finish the valentine by sprinkling gold or silver glitter.

The probability that her valentine to her friend will be on either red or pink construction paper with black marker and gold glitter.

The probability that she uses red or pink construction paper = (2/3)

(since red or pink are two out of the total 3 sample spaces available for construction paper)

Probability that she uses black marker = (1/3)

(Black is one of the 3 sample spaces for markers)

Probability that she uses gold glitter = (1/2)

(Gold glitter is one of two sample spaces for glitters)

The required probability is then

(2/3) × (1/3) × (1/2) = (1/9)

Hope this Helps!!!

the legs of a right triangle have lengths of 28 meters and 21 meters. the hypotenuse has a length of 5x meters. what is the valu
Hitman42 [59]
We have a right triangle with
a = one leg = 28
b = other leg = 21
c = hypotenuse = 5x

use the pythagorean theorem (a^2+b^2 = c^2) and solve for x

a^2+b^2 = c^2
28^2+21^2 = (5x)^2
784+441 = 25x^2
1225 = 25x^2
25x^2 = 1225
(25x^2)/25 = 1225/25
x^2 = 49
sqrt(x^2) = sqrt(49)
|x| = 7
x = 7 or x = -7

Since the hypotenuse has length 5x meters, this means
5x = 5*7 = 35
or
5x = 5(-7) = -35

Toss out the negative length as it makes no sense. 

The only value of x is x = 7

Therefore the final answer is x = 7

How do I solve a system of equations using substitution?
Sonbull [250]

Answer:

A way to solve a linear system algebraically is to use the substitution method. The substitution method functions by substituting the one y-value with the other. We're going to explain this by using an example. We can substitute y in the second equation with the first equation since y = y.

Hope This Helps!   Have A Nice Day!!
