This can be solve by first solving the proportionality constant

Number electic outlets rewired is directly proportional to time spent

4 = (1 ½)a

Let be the proportionality constant

A = 8/3

O = (8/3)(7.5)

o = 20 outlets will jamal rewired if he works for 7.5 hrs

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
Nat2105 [25]
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.

A pair of pants was on sale for 40% off. The sale price of the pants was $18.00. What was the original price of the pants?
iragen [17]

Answer:

The original price of the pants was $30.

Step-by-step explanation:

Let x be equal to the original price of the pants.

Because the pants are 40% off, their final price was 60% of the original price. 60% as a decimal is 0.6. Using this information, we can set up the following equation and solve:

0.6x=18

Divide both sides by 0.6

0.6x/0.6=18/0.6

x=30

I hope this helps!

Ron works 5 hours for a total of $300. He deposits all of his money in his account. He is trying to save $500 for a new LED TV.
hoa [83]
He must work about 4-5 more hours, and if he works 4 hours, he would earn $240, and $300 + $240 = $540. Or, if he works for 5 hours, it would equal $300. $300 + $300 IS $600, and his savings may be $60 or $100. Your Choice.
