Answer/Step-by-step explanation:
The missing length can be found by applying pythagorean theorem. Thus:
Missing length = √((8x)² - (2x)²)
Missing length = √(64x² - 4x²)
✔️Missing length = √(60x²) = 2x√15
Plug in the value of x which is 3
Missing length = 2*3√15
✔️Length = 6√5
Answer:
2.5 or 10/4
Step-by-step explanation:
2÷4/5
Integers can be fractions. Which are just the summation of equal parts. So integers can be written in any fractional form as you like,
2/1÷4/5
But turning your fraction into an integer is not enough to divide, you must first use the reciprocal form of your dividend. and then you multiply to obtain your answer. (The reason is that division is multiplication of the reciprocal)
2/1×5/4
And tadaa! you get your answer
10/4
You can also simplify it!
5/2
7cm each. reason: the rod of 21cm lenght will be cut into 3pieces of 7cm each, while that of 14cm will be cut into 2 pieces of 7cm each. Therefore, there 5 pieces of rods of 7cm each. Thanks.
