Question 1:
 The angle m∠DOX is greater than 90 degrees, but less than 135 degrees.
 Looking at the diagram we see that:
 m∠DOX = 120 degrees.

 Question 2:
 The angle m∠COX is the sum of two angles that in total are 80 degrees.
 Therefore, the equation is:
 m∠COX = m∠AOX + m∠COA
 
 Question 3:
 
The BOA angle measurement is given by:
 BOA = 60 - 40
 BOA = 20 degrees
 Therefore, an angle that measures 20 degrees is:
 BOA.

 Question 4:
 
From the previous question we have:
 m∠BOA = 60 - 40
 m∠BOA = 20
 The measure of m∠BOA is 20 degrees

 Question 5:
 The measure of the angle EOD is given by:
 m∠EOD = 140 - 120
 m∠EOD = 20 degrees

If 5 tractors can plow a field in 4 hours, how many hours will it take 3 tractors to plow the field?
Mrac [35]

The number of hours required for 3 tractors to plow the field is 2.4 hours

<em><u>Solution:</u></em>

Given that 5 tractors can plow a field in 4 hours

We have to find out number of hours required for 3 tractors to plow the field

5 tractors can plow a field in 4 hours, So time taken for 1 tractor

\text{ time taken for 1 tractor } = \frac{\text{ time taken for 5 tractor}}{5}

\text{ time taken for 1 tractor } = \frac{4}{5} \text{ hours }

<em><u>So time taken for 3 tractors is given as:</u></em>

time taken for 3 tractor = time taken for 1 tractor x 3

\text{ time taken for 3 tractor} = \frac{4}{5} \times 3 = \frac{12}{5}

\rightarrow \frac{12}{5} = 2.4

So number of hours required for 3 tractors to plow the field is 2.4 hours

Bill weighs 80 kilograms and is gaining 2 kilograms each month. Phil weighs 65 kilograms and is gaining 5 kilograms each month.
Lynna [10]
Using the formula for the nth term of an arithmetic sequence we can write:
80 + (n - 1)2 = 65 + (n - 1)5
80 + 2n - 2 = 65 + 5n - 5
3n = 18
n = 6
The answer is 6 months.
