My parents recently moved to the Poconos, they got 30 or more inches of snow from this last snow storm. It took my Dad 2 hours t
never [62]

To determine how much will it take to clean a 120ft driveway considering that it took him 2hs to clear 10ft and that the cleaning rate is constant, you can use cross multiplication:

10ft______2hs

120ft_____xhs

If the cleaning rate is the same, then the ratios between both are the same:

\frac{2}{10}=\frac{x}{120}

From this expression, you can determine the time by multiplying both sides of the equal sign by 120

\begin{gathered} 120(\frac{2}{10})=\frac{120x}{120} \\ 24=x \end{gathered}

It will take him 24 hours to clear the 120ft driveway.

One student can paint a wall in 16 minutes. Another student can paint the same wall in 24 minutes. Working together, about how l
Mazyrski [523]
Let's look at work rates per minute.

Together they can paint the wall in x minutes.
Working together, in 1 minute, they do 1/x of the job.

The student who paints the wall in 16 minutes does 1/16 of the job in 1 minute.
The student who paints the wall in 24 minutes does 1/24 of the job in 1 minute.
Together, they do 1/16 + 1/24 of the job in 1 minute, but from above, we see that together, they do 1/x of the job in 1 minute, so 1/16 + 1/24 must equal 1/x. That gives us our equation.

1/16 + 1/24 = 1/x

1/16 * 3/3 + 1/24 * 2/2 = 1/x

3/48 + 2/48 = 1/x

5/48 = 1/x

x = 48/5 = 9.6

Answer: It takes them 9.6 minutes, or about 10 minutes to do the job together.

Answer: A=100(12)t5.27


Step-by-step explanation:

Assume / and ^ got lost from eqns.

A(t) = initial × (1/2)^(t/halflife)

So initial = 100, halflife = 5.27,

A=100(12)t5.27 means A=100(1/2)^(t/5.27)

so that A is 50 when t is 5.27
