Find the circumference of one wheel and then mult. that by 18:

C = 2*pi*r         becomes    C = 2*pi(1.14 m) =  2.28*pi m

Distance traveled:        18*C = 41.04*pi meters, or approx. 129 meters

Sarah says that you can find the LCM of any two whole numbers by multiplying them together. Provide a counter example to show th
xenn [34]

Answer:

  4·6 = 24 ≠ 12 = LCM(4, 6)

Step-by-step explanation:

Any pair of numbers with a common factor will refute Sarah's conjecture.

One such pair is 4 and 6, which have a product of 24. The LCM of 4 and 6 is 12, which is that product divided by their common factor of 2.

I if the no of Girates at congtin were reduced by 63% what would be the approximate ratio of giraffes to animals in other catego
Arada [10]

Answer:

Giraffe:Others = 3:7

Step-by-step explanation:

<em>See Attachment for complete question</em>

For this question, we only need the data at the Congtin column.

So, we have:

Giraffes = 124

Other = 108

First, we need to reduce Giraffe by 63%.

This gives:

New\ Giraffe = Giraffe - 63\% * Giraffe

New\ Giraffe = 124 - 63\% * 124

New\ Giraffe = 124 - 78.12

New\ Giraffe = 45.88

Represent this as a ratio:

Giraffe:Others = 45.88:108

The closest to this ratio is 3:7.

This is shown by dividing the ratio by 15

i.e.

Giraffe:Others = 45.88/15:108/15

Giraffe:Others = 3.0589:7.2

Approximate:

Giraffe:Others = 3:7

2/5 plus 1/4 plus 7/10
Jobisdone [24]

The answer is 1 7/20

2/5 x 4/4 + 7/10 x 2/2 + 1/4 x 5/5

=  8/20 + 14/20 + 5/20

= 27/20

= 1 7/20
