A squirrel burrowed 6 holes in 2 minutes. How many holes could the squirrel burrow in 7 minutes?

Answers

7 minutes= 2 minutes x 3.5

The squirrel burrowed 6 holes in 2 minutes.
To find how many holes the squirrel burrows in 7 minutes we multiply 6 x 3.5= 21.

Alternate method:

If the squirrel burrows 6 holes in 2 minutes that means he has burrowed 3 holes in 1 minute.
Multiply the number of holes burrowed in 1 minute by 7 to get 21.

Answer:

21 holes

Step-by-step explanation:

6 holes/2 minutes = x/7 minutes (cross multiply)

(6*7)/2 = 42/2 = 21 holes

What is Proportion?

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

A person is standing 24 feet away from a street light that is 25 feet tall.

let the height of person be x when its height of shadow is 6 feet.

Using Proportion

x/ 6 = 25 / 30

30x =150

x= 150/ 30

x= 5 feet

Hence, the height of the person is 5 feet.

Answers

Using the probability concept, it is found that there is a [tex]\frac{4}{9}[/tex] probability that the second chosen is also a boy.

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, supposing that the first person chosen is a boy:

There will be 27 students.Of those, 12 are going to be boys.

Hence:

[tex]p = \frac{12}{27} = \frac{4}{9}[/tex]

There is a [tex]\frac{4}{9}[/tex] probability that the second chosen is also a boy.
