The proportion to solve for the entire cost of fence is 29 / 3 meters = entire cost / x meters (or) entire cost = (29 × x meters) / 3.
<u>Step-by-step explanation:</u>
Given that,
- Cost of 3 meters of fence = $29.
- Let, the entire fence be 'x' meters.
Therefore, the cost of entire fence is calculated by comparing the given data.
29 / 3 meters = entire cost / x meters
<u>To find the entire cost :</u>
The proportion is given by,
29/3 = entire cost / x
entire cost = (29 × x meters) / 3
The above proportion must be solved to find the entire cost of fence.
Answer:
In total there are 50 students.
Step-by-step explanation:
Since in a group of students 20 study account, 21 study mathematics, 18 study history, 7 study account only, 10 study mathematics only, 6 study account and mathematics only and 3 study mathematics and history only, to determine how many student are there altogether the following calculation must be performed:
7 + 10 + 6 + 3 = 26
Account = 20 - 7 - 6 = 7
Mathematics = 21 - 10 - 6 - 3 = 2
History = 18 - 3 = 15
26 + 7 + 2 + 15 = X
50 = X
Therefore, in total there are 50 students.
