Max can mow a lawn in 45 minutes. Jan takes twice as long to mow the same lawn. If they work together, how long will it take the

lilavasa [31]

Max mows a yard in 45 minutes and Jan takes twice as long mowing the same yard. If Max and Jan both work together, it will take approximately 30 minutes to for them both to mow the yard.

It take Max 1 minute to mow 1/45 of the yard.
It takes Jan 1 minute to mow 1/90 of the yard.

1/45+1/90 =3/90 = 1/30 of the yard can be mowed by both in just one minute. This is how to get the answer, 30 minutes.

James had a peach that was 98mm in diameter. One day he watered it with a magical solution, and it grew to 188,869 mm in diamete

Archy [21]

We know that 98mm is the 100% of the diameter of the plant before James watered with the magical solution; after he watered, the diameter of the plant grew to 188.869mm. Let $x$ be the grew in the percentage of the diameter.
Now we can establish a ratio and solve for $x$ :
$\frac{98}{100} = \frac{188.869}{x}$
$x= \frac{(188.869)(100)}{98}$
$x=192.7$ %
Now that we know the diameter of the plant grew 192.7%, we just need to divide that quantity by 100% to find how many times the diameter grew:
$\frac{192.7}{100} =1.927$

We can conclude that the diameter of the peach <span>become approximately 1.9 times larger after James watered it.</span>
