ANSWER:

24 minutes

40% of 1 hour is equivalent to 24 minutes.

STEP-BY-STEP EXPLANATION:

1 hour = 60 minutes

If:

100% = 60 minutes

Then:

100% ÷ 2.5 = 60 minutes ÷ 2.5

40% = 24 minutes

THEREFORE:

40% of 1 hour is equivalent to 24 minutes.

Michelle is building a rectangular landing strip for airplanes .She has material to cover 1/1,500 of a square mile. The landing

ANEK [815]

I think that the missing word here is:
"with the amount of the material that Michelle has"

Let's say that her landing strip is x miles long, then its area would be:

$\frac{1}{6} *x$

We also know how big it is:

$\frac{1}{6} *x= \frac{1}{1 500}$

now, let's multiply both sides by 6:
$\frac{6}{6} *x= \frac{6}{1 500}$
$1 *x= \frac{3}{750}$
$x= \frac{1}{250}$

So the answer is that it would be $x= \frac{1}{250}$ miles wide

A circular garden is enlarged so that the new diameter is twice the old diameter. What is the ratio of the original area to the

Amanda [17]

Answer:

Explained briefly below.

Step-by-step explanation:

For old circular garden:

take the radius as r.

then use the formula to find area of circle: πr² ......this is old garden area.

For new enlarged garden:

the radius is twice the old radius so, radius = 2 * r = 2r ......enlarged radius

now find area for this new garden: π(2r)² → 4πr²

In common fractions: (old garden)/(new garden)

: ( πr² ) / ( 4πr² )

: 1/4
