Answer: 20 ways
Step-by-step explanation:
Given: There were 5 women, 4 men, 6 girls and 7 boys at a birthday party.
i.e. Number of women = 5
Number of men = 4
According to the fundamental counting principle , we have
(Number of women ) x (Number of men)
= 5 x 4
= 20
Hence, 1 woman and 1 man can be chosen in 20 ways to take coats.
Answer:
21
Step-by-step explanation:
I wil call the length l and the width w in the following. We are given these informations:
The area of the rectangle is 105. That means l * w = 105. (1)
The length is 16 inches longer that the width. That means l = w + 16. (2)
If we plug the information we get from (2) into the equation (1), we get:
(w + 16) * w = 105
Simplify and you get
w² + 16 w - 105 = 0
With the the quadratic formula we get the results w = 5 and w = -21. The negative result doesn't make sense for our task, we are only interested in positive length and width :).
If we now plug w = 5 back into our infromation (2), we get:
l = 5 + 16 = 21
(To confirm the result plug w = 5 and l = 21 into (1))
Answer:
One clay block = x = $2.50 from before.
One mold = y = $4.00
Step-by-step explanation:
Multiply the second one by -2 to get -12x-2y=-38.00
Add these equations to eliminate y:
-12x-2y=-38.00
3x+2y=15.50
Result: -9x+0y=-22.50
9x=22.50
x=$2.50

Answer:
<u>If mixed numbers are </u>
<u>You can write them as a sum of a whole and fraction and use the distributive property of multiplication:</u>
- a b/c × d e/f =
- (a + b/c) × (d + e/f) =
- ad + a(e/f) + d(b/c) + (b/c)(e/f)
