To paint a house, two painters are hired. The first painter can paint the house in ten hours. The second painter will need six hours to paint the entire house. If the two painters start painting at 8:00 am, at what time will they finish painting the house?

Answers

so
p1 can paint hours in 10 hours, so 1/10 house per 1 hour

p2 can paint house in 6 hours so 1/6 house per 1 hour

if both start at 8:00, when finish??
find how many hours they take

1 hour=p1+p2=1/10+1/6
just add 1/10 and 1/6 and see how many to get 1/1 house done
1/10+1/6=3/30+5/30=8/30=4/15
xhours times 4/15=1
multiply both sides by 15/4 to clear fraction
xhours =15/4
xhours=3 and 3/4

they take 3 and 3/4 hours aka 3 hours and 45 mins so
8:00+3:45=11:45

they finish at 11:45 AM

What values of b satisfy 3(2b + 3)2 = 36?

Answers

the correct question is

What values of b satisfy 3(2b+3)^2 = 36

we have

$3(2b+3)^2 = 36$

Divide both sides by $3$

$(2b+3)^2 = 12$

take the square root of both sides

$( 2b+3)} =(+ /-) √(12) \n 2b=(+ /-) √(12)-3$

$b1=(√(12))/(2) -(3)/(2)$

$b1=√(3) -(3)/(2)$

$b2=(-√(12))/(2) -(3)/(2)$

$b2=-√(3) -(3)/(2)$

therefore

the answer is

the values of b are

$b1=√(3) -(3)/(2)$

$b2=-√(3) -(3)/(2)$

What numbers add to 8 and multiply to 11

Answers

There is no answer to your question. I will prove so.

the only factor pair of 11 is:

11&1

But, while these two number have a product of 11, they do not have a sum of 8

11+1=12
11+1≠8

You go to the doctor and he gives you 13 milligrams of radioactive dye which decays exponentially. After 24 minutes, 5 milligrams of dye remain in your system. To leave the doctor's office, you must pass through a radiation detector without sounding the alarm. If the detector will sound the alarm if more than 2 milligrams of the dye are in your system, how long will you have to remain at the doctor's office, assuming you were given the dye as soon as you arrived? Give your answer to the nearest minute.You will spend?
