Perimeter of 60 , length is 3 times the width, what are the dimensions

1 answer:

7 0

Length - l

Width - w

Given,

Perimeter = 60

2(l +w) = 60

l + w = 30

l = 30 - w

Given,

l = 3w

30 - w = 3w

4w = 30

--- w = 7.5

--- l = 3w = 3 * 7.5 = 29.5

Hence, the length of the rectangle is 29.5 and the width is 7.5

MrRa [10]

2,500,000/365 = 6849 per day.
6849/24 = 285 per hour.
285/60 = 4.75 which is rounded to 5.
So 5 per minute

choosing a vowel from the word counting and a consonant from the word Prime then give the total number of outcomes

yKpoI14uk [10]

Answer:

Step-by-step explanation:

Total letters in word 'COUNTING'=8

Number of vowels in word 'COUNTING'=3(O,U,I)

Total letter in word 'PRIME'=5

Number of consonants in word 'PRIME'=3(P,R,M)

We have to find the total number of outcomes.

Number of choice for O=3(P,R,M)

Number of choice for U=3(P,R,M)

Number of choice for i=3(P,R,M)

Number of outcomes of choosing a vowel from the word 'COUNTING' and a consonant from the word 'PRIME'=3+3+3

Total number of outcome=9
