Answer:
1/2
Step-by-step explanation:
since 10petrols=1 oil
therefore 5petrols=1/2
Answer:
118
Step-by-step explanation:
Triangle CDE contains angles CDE, DCR and DER
Angles DCR=17 and DER=45 because in a kite, the diagonal on the line of symmetry bisects the angles and 34-2=17 90/2=45
The angles in a triangle add up to 180 and 180-17-45=118, meaning angle DER=118
Answer:
9.49
Step-by-step explanation:
Divide 47.45 by five to find the answer.
Given:
The expression is

To find:
The simplified form of the given expression.
Solution:
We have,

It can be written as

![[\because a^2-b^2=(a-b)(a+b)]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E2-b%5E2%3D%28a-b%29%28a%2Bb%29%5D)
Taking LCM, we get




Cancel out the common factors.

Therefore, the simplified form of the given expression is
