It takes 28 minutes for 7 people to paint 7 - 1

Answers

Answer 1
Answer:

Answer: 28 minutes


Step-by-step explanation:

If M1 men can do W1 work in working H1 hours per day and M2 men can do W2 work in working H2 hours per day (where all men work at the same rate), then

(M_1H_1)/(W_1)=(M_2H_2)/(W_2)\n\Rightarrow(7*28)/(7)=(14H_2)/(14)\n\Rightarrow(28)/(1)=H_2\n\Rightarrow\ H_2=28

hence, It takes 28 minutes for 14 people to paint 14 walls.

Answer 2
Answer: Well, since you have twice as many people and twice as many walls. It would take them also 28 minutes to paint all the walls.
Hope I helped!

You toss a coin three times. What is the probability that it will land heads all those three tosses ?

Answers

The probability would be 1 in 8, or 12.5%
- toss three times
- each time = 2 different possibilities
-3 x 2= 6 chances for heads or tails
6÷2 = 3
-3/6 chances = 50% chance

The probability is 50% or 1/2 to get heads once

to get all three times would be 1/8 or 12.5%

Kevin spends $11.25 on lunch every week during the school year. If there are 35.5 weeks during the school year, how much does Kevin spend the entire school year?Remember to round to the nearest penny.

Answers

First, you multiply. You get $399.375. when you round it to the nearest penny, look behind the decimal, see if it's going down to 0, or going higher than 5, then round. the overall answer is going to be..............$399 and 40 cents.
Lunch per week times weeks total
11.25×35.5=399.375
rounded to the nearest penny is the same as the hundredths place which is $399.38 since the next decimal place is 5 or more
