Answer:
a1
Step-by-step explanation:
Just add the numerators if both fractions to get: a + 1 = a1
Answer: Choice D
Explanation:
The increase of 9.8% rounds to 10% when rounding to the nearest ten
An increase of 10% would use the multiplier 1.1
Think of it like saying 1 + 0.10 = 100% + 10%
Similarly, the 5.1% rounds to 5% and an increase of this amount will use the multiplier 1.05
So if we started with 20 items, then 20(1.1)(1.05) is the expression that estimates an increase of 10% followed by an increase of 5%. The order doesn't matter (so you could increase by 5% first, then 10% later).
The answer is 1 + √2
sqrt(2) is
sqrt(3 + 2 sqrt 2) is
Now, let's simplify
.
We will use square of sum: (a + b)² = a² + 2ab + b²
