15 tractors each working 8 hours a day take to take eight days to Plough a piece of land how many days will it take 24 tractors each working 10 hours a day to plough the same piece of land
Answers
It will take 24 tractors, each working 10 hours a day, a total of 4 days to plough the same piece of land.
To determine how many days it will take 24 tractors, each working 10 hours a day, to plough the same piece of land, we can use the concept of man-hours.
Given that 15 tractors, each working 8 hours a day, took 8 days to complete the task, we can calculate the total man-hours required to plough the land.
Total man-hours = Number of tractors * Hours per tractor * Number of days
Total man-hours = 15 tractors * 8 hours/tractor * 8 days
Total man-hours = 960
Now, let's calculate the number of days required for 24 tractors, each working 10 hours a day, to complete the task.
Number of days = Total man-hours / (Number of tractors * Hours per tractor)
Number of days = 960 / (24 tractors * 10 hours/tractor)
Number of days = 960 / (240)
Number of days = 4
As a result, ploughing the same plot of land will require 24 tractors to labour for a total of 4 days at 10 hours per day each.

Answer:
Option C √32 is correct
Step-by-step explanation:
Here,
x₁ = 8
x₂ = 4
y₁ = (-3)
y₂ = (-7)
Now,
By Using Distance Formula
D = √(x₂ - x₁)² + (y₂ - y₁)²
= √(4 - 8)² + [(-7) - (-3)]²
= √(-4)² + [(-7) + 3]²
= √16 + (-4)²
= √16 + 16
D = √32
Thus, The distance between (8, -3) and (4, -7) is √32

Taylor is producing graphic T-shirts that
will come in three different colors. He
randomly surveys 100 people, asking which
one of the three colors they prefer. Of the
100 people surveyed,55 say that they prefer
the white T-shirt. If Taylor is going to produce
500 graphic T-shirts, about how many should
be white?
Answers
If Taylor is producing graphic T-shirts that will come in three different colors then about 275 graphic T-shirts should be white.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Since Taylor randomly surveyed 100 people and 55 of them said they prefer the white T-shirt
we can estimate the proportion of people who prefer the white T-shirt as:
p = 55/100 = 0.55
We can assume that this proportion is a good estimate of the true proportion of people who will prefer the white T-shirt among all potential customers.
To estimate the number of people who will prefer the white T-shirt among 500 potential customers
The formula for the expected value of a binomial random variable is
E(x) = np
Substituting the values, we get:
E(x) = 500 × 0.55 = 275
Therefore, about 275 graphic T-shirts should be white.

His pay gets income tax deducted at a rate of 18% = 18/100
That means you multiply is weekly wage by 18/100 to get what the government takes off.
Solution
18/100 * 495 = 80.10
The government takes $80.10
His take home pay is 495 - 80.10 = $405.90
Note:
There is a short way of doing his take home pay if that is all you are interested in. His take home pay is 82% of his gross pay which is 82/100 * 495.
82/100 * 495 = 405.90
