the number of buckets of paint n needed to paint a wall varies jointly with the total area a and the thickness t of the wall, an

d inversely with the amount of paint p. It takes five 2 gallon buckets of paint to paint 100 square feet of wall with thickness 3 inches.What is the area of the wall with thickness 6 inches can eight 2 gallon buckets paint

The number of buckets is directly proportional to the area and the thickness of the wall and inversely proportional to the amount of paint. Mathematically, we can write:

n = k · (a · t) / p

where k is the proportionality constant which we do not know.

We can calculate k with the given data: 5 2-gallon buckets, area of 100 square feet and thickness 3 inches:

k = (n · p) / (<span>a · t)
   = (5 </span>· 2) / (100 · 3) = 0.0333

Now that we know the constant, we can calculate the area that can be painted with 8 2-gallon buckets if the thickness is 6 inches:

a =  (n · p) / (k<span> · t)
   = (8 </span>· 2) / (0.0333 · 6)
   = 80 ft²

Please, note that we made sure to have the exact same units of measurements than the previous case.

Therefore, the correct answer is an area of 80 ft².

Katrina deposited $500 into a savings account that pays 4% simple interest. How much interest will she earn in 3 years if she ma
Dovator [93]

Answer: the amount of interest after 3 years is $60

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the amount of money deposited.

P represents the principal or amount of money deposited.

R represents interest rate on the deposit.

T represents the duration of the deposit in years.

From the information given,

P = $500

R = 4%

T = 3 years

Therefore,

I = (500 × 4 × 3)/100

I = $60

Val paid $123 for x days for renting a bicycle where as $8.50 was rent of bicycle per day so dividing $123/8.50 gives us number of days

which are 14.47 days.

$55 amount is ambiguous that whether it was flat ( as in apartment) rental fee or what?
