If 15 workers can paint 18 houses in 24

Mathematics
1 answer:
Rasek [7]3 years ago
6 0

Answer: 11

Step-by-step explanation:

If 15 workers can paint 18 houses in 24 days, how many days will 40 workers take to paint 22 houses?

--------------

# of days are inversely related to # of workers and directly related

to # of houses.

--------------

d = kh/w

---

Solve for "k" using "15 workers can paint 18 houses in 24 days"

24 = k*18/15

k = 15*24/18 = 15*(4/3) = 20

--------------

Equation:

d = 20h/w

---

Solve: How many days will 40 workers take to paint 22 houses?

d = 20*22/40

d = 11 days

A bag of jelly beans contains 10 red,6 green,7 yellow, and 5 orange jelly beans.What is the probability of randomly choosing a r
lilavasa [31]

Answer:

\text{The Probability is = }\frac{125}{5488}\approx 0.02

Step-by-step explanation:

No. of red jelly = 10

No. of green jelly = 6

No. of yellow jelly = 7

No. of orange jelly = 5

Total number of jelly = 10 + 6 + 7 + 5 = 28

\text{So, Probability of choosing red jelly, P(R) = }\frac{10}{28}=\frac{5}{14}\\\\\text{So, Probability of choosing orange jelly, P(O) = }\frac{5}{28}\\\\\text{Now, Probability of choosing first red , then red and then orange jelly}\\\text{on replacing each jelly after choosing, }\\\\P(R,R,O) = \frac{5}{14}\times \frac{5}{14}\times \frac{5}{28}=\frac{125}{5488}\approx 0.02

Hence, the required probability is 0.02 or 2 %

What is the approximate volume of the sphere?
muminat
Your best bet is A. 524

Use the formula V=4/3(pi)r^3  or  v =  \frac{4}{3}  \pi r ^{3}

Not sure if that made sense but you need to multiply to radius(cubed) by pi and divide it by 4/3

Next time just google the volume formula of a sphere
