Answer:
y=90 degrees
Step-by-step explanation:
x+y+70=180 degrees ==> these three angles make up a triangle, and the
the total sum of angles in a triangle is 180 degrees
Notice that y is on a straight line?
Straight lines are 180-degree angles called straight angles.
Hence:
(180-y)+x+70=180 ==> these three angles also make up a triangle, and the
the total sum of angles in a triangle is 180 degrees
180-y+x+70=x+y+70 ==> since both expressions equal 180, they both are
equal to each other
180-y+x+70 + y = x+y+70 + y ==> add y on both sides to isolate y to one side
180 - y + y + x + 70 = x + y + y + 70 ==> simplify
180 + x + 70 = x + 2y + 70
180+x+70 - x = x+2y+70 - x ==> subtract x on both sides to eliminate x
180 + x - x + 70 = x - x + 2y + 70 ==> simplify
180 + 70 = 2y + 70
180 + 70 - 70 = 2y + 70 - 70 ==> subtract both sides by 70 to simplify the equation
180 = 2y
y = 180/2
y = 90 degrees

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

Remark
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

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.
