Answer:
A. How many paperback books each person buys.
Step-by-step explanation:
In the equation the x represents how many paperback books they can buy.
In the equation the 2 represents that 1 hardcover book was purchased.
In the equation the 35 represents how much money they spent in total.
The equation is complete except for x which has to be substituted with how many paperback books they can buy. Which would be 5.

Answer:
<h2>
$400</h2>
Step-by-step explanation:
Using the formula for calculating the simple interest expressed as;
Simple Interest = Principal * rate * time/100
Note that the principal is the amount he originally borrowed
I = PRT/100 ............ 1
Amount paid off A = Principal+Interest
A = P+I ............ 2
From equation 2; I = A-P......... 3
Substitute equation 3 into 1;
A-P = PRT/100
Given A = $440, R = 10%, Time = 1year
Substitute the given parameters into the resulting equation;
440 - P = P*10*1/100
440-P = 10P/100
440-P = 0.1P
440 = 0.1P+P
440 = 1.1P
Divide through by 1.1;
1.1P/1.1 = 440/1.1
P = $400
<em>Hence the amount Mr Noel originally borrow is $400</em>

There are mainly six trigonometric functions for right angle triangle which are
- sinФ
- cosФ
- tanФ
- cosecФ
- secФ
- cotФ
All of these can be expressed in the form of sinФ and cosФ as following:
- sinФ = sinФ
- cosФ = cosФ
- tanФ = sinФ/cosФ
- cosecФ = 1/sinФ
- secФ = 1/cosФ
- cotФ = cosФ/sinФ
This angle Ф is shown in the attached drawing in a right angle triangle drawn within a circle which is the given angle. Right angle is mentioned as "90".
379.88 is the answer to this problem.
