What is the highest common factor of 27 and 36?

1 answer:

3 0

Hello there!

The highest common factor, also known as the greatest common factor, or GCF, is the biggest factor that both numbers have in common.

Let's factor out our numbers.

27;
1 x 27
3 x 9

36;
1 x 36
3 x 12
4 x 9
6 x 6

Both of these numbers have these in common:
1, 3, 9.

Since 9 is the highest number in common, it is our GCF or highest common factor.

I hope this helps!

Find the circumference of a circle r=9

kvasek [131]

Answer:

254.34

Step-by-step explanation:

You first have to know the formula which is

$c = \pi \: {r}^{2}$

You multiply 9 by 9 which gives you 81.

$c = \pi \times 81$

pi equals 3.14

so 3.14 × 81 = 254.34

An advertiser drops 10,000 leaflets on a city which has 2000 blocks. Assume that each leaflet has an equal chance of landing on

Ira Lisetskai [31]

Answer:

0.00673

Step-by-step explanation:

As each of the 10000 leaflets has equal chance on landing into 1 of the 2000 blocks, this means each leaflet has a probability of 1/2000 to land on the 1st block, 1/2000 to land on the 2nd lock, 1/2000 to land on the 3rd block, and so on.

The probability that a particular block will receive no leaflet is chance of each leaflets to land on the other 1999 blocks, which has a chance of 1999/2000. For all 10000 leaflets to happen like this independently, then the total probability is

$\left(\frac{1999}{2000}\right)^{10000} = 0.00673$
