Math Mid Term Help

Introduction to math mid term help:

Math mid term help is the practice problems for math mid term exam. Mid term exam is conducted to check the performance of  students. Math mid term help covers many topics under mathematics. Below given some of examples and practice problems to math mid term help. Math lessons are used in real life situations such as counting the money, calculating time, measuring weight, measuring distance, etc. In this article math mid term help let us see practice problems and practice exam with solutions.


Example Problems - Math mid term help:


Example 1:

Calculate median of the values

55, 65, 23, 11, 77

Solution:

Arrange in ascending order

11, 23, 55, 65, 77

Median = 55

Example 2:

Find the factor of 17

Solution

We know that 17 is a prime number

All the prime numbers have only two factors

The two factors are 1 and the numbers itself

So the factor of the number 17 is 1 , 17 alone.

Example 3:

Find the area of triangle if its base is 20cm and height is 9 cm.

Solution:

The formula for area of triangle = ` (1 /2 xx base xxheight)`

Here, base = 20 cm

height = 9 cm

Therefore, area of triangle = `(1/2)xx20xx9 `

= `(1/2)xx 180`

= 90 cm^2.


Few More Example Problems - Math mid term help:

Example 4:

Evaluate  25 – 6 × 2 +6

Solution:

Here we use PEMDAS rule for solving the problem since it has various operations to perform

From this question there is no parenthesis exponents and division.

So we perform multiplication first.

6 × 2 = 12

25 -12 + 6

13 + 6

The answer is 19.

Example 5:

Find the value of a in the given

4a + 40 = 0

Solution:

Subtract 40 on both side

5a + 40 -40 = -40

5a = -40

a =-`40/5`

a = -8
