Mathematics
1 answer:
boyakko [2]3 years ago
6 0

Answer:

7.17 cm

Step-by-step explanation:

If the width is x, the length is twice this  = 2x

And

Perimeter = 2 (W + L)

so

Perimeter =  2 ( x + 2x)

Perimeter  = 2 (3x)

Perimeter  = 6x

43  =  2 ( x + 2x )

43= 2 ( 3x)  

43  =  6x

= 7.17 cm

Hope this helps i'm pretty sure this is how you do it :-)

A month of the year is chosen at random. What is the probability that the month starts with the letter J or the letter M?
Flauer [41]

Answer:

The probability that the month starts with the letter J or the letter M is 41.66%.

Step-by-step explanation:

Given that a month of the year is chosen at random, to determine what is the probability that the month starts with the letter J or the letter M, the following calculation must be performed:

January - March - May - June - July = 5 months

(5/12) x 100 = X

0.4166 x 100 = X

41.66 = X

Therefore, the probability that the month starts with the letter J or the letter M is 41.66%.
