Introduction to solve math student solutions:
Mathematics is a vast area.Some of the main branches of mathematics are algebra, geometry, trigonometry and calculus. There are number of math problems available under these branches for the students. In this article solve math student solutions, we are going to solve for some basic math solutions which are useful for the students. In addition, some practice problems are given to solve.
Having problem with Derivative Trigonometric Functions keep reading my upcoming posts, i will try to help you.
Solved examples for math solutions:
Example 1:
Andrew bought a camera for `$` 100 and he sold it for `$` 110. Find the gain amount.
Solution:
cost price of camera = $ 100
selling price of camera = $ 110
Gain = selling price - cost price
= 110 - 100
= $ 10
Example 2:
Find the area of circle if the radius is 79 cm.
Solution:
Area of circle = `pi` r^2
= 3.14 (79)2
= 3.14 * 6241
= 19596.74 cm^2
Example 3:
Spears bought an ornament that costs `$` 1000. If the sales tax rate is 10%. What is the total amount she must pay for the ornament?
Solution:
Sales tax = 10% of the price tax
= 10% x 1000
= 0.10 x 1000
= 100
Final price = price before the tax + sales tax
= 1000+ 100
= $ 1100
Example 4:
A basket contains 750 eggs. 680 were not broken. What percentage of the eggs were broken?
Solution:
Total number of eggs = 750
Number of eggs not broken = 680
Number of eggs broken = 750 - 680
= 70
Percentage of eggs broken = `<< 70/750>>` x 100
= `<< 7/75>>` x 100
= 9.3
Example 5:
Find the area and perimeter of rectangle, if the length is 35 m and breadth is 15 m.
Solution:
Area of rectangle = l * b
= 35 * 15
= 525 m^2
Perimeter of rectangle = 2 ( l + b )
= 2 ( 35 + 15 )
= 2 ( 50 )
= 100 m
Practice problems to solve:
1) Sarah bought a ring for `$` 1800 and she sold it for `$` 1880. Find the gain amount.
Answer: Gain = `$` 80
2) Find the area of circle if the radius is 16 cm.
Answer: Area = 803.84 cm^2
3) Mercy bought an ornament that costs `$` 1700. If the sales tax rate is 9%. What is the total amount she must pay for the ornament?
Answer: Amount = `$` 1853
4) A basket contains 200 eggs. 180 were not broken. What percentage of the eggs were broken?
Answer: Percentage = 10
5) Find the area and perimeter of rectangle, if the length is 28 m and breadth is 7 m.
Answer: Area = 196 m^2 Perimeter = 70 m
