Answer:
b) 1.22
Step-by-step explanation:
22% as a decimal is 0.22. But we want to increase the number, meaning that we have to keep it to start, or multiply it by 1. And then we also multiply by 0.22. Thus multiplying by 1.22.
The percentage multiplier to increase a quantity by 22% is 1.22. You calculate this by adding the percentage increase as a decimal to 1.
The question asks for the percentage multiplier to increase a quantity by 22%. This falls within the domain of mathematics, particularly algebra and critical numeracy skills.
To calculate a percentage increase, you would start with the original amount represented as 1 (or 100%), and then add the percentage increase as a decimal.
So, for a 22% increase, you would add 0.22 to 1, which results in 1.22.
Therefore, the correct answer to the question is b. 1.22.
This multiplier is then applied to the quantity you wish to increase, effectively increasing it by the desired percentage.

Answer:
the parabola opens down
Step-by-step explanation:
Select the direction that this parabola opens.
y=-x^2/20
To find the direction of the parabola y=ax^2 +bx+c ,we need to consider the value of 'a'
If 'a' is positive then the parabola opens up
If 'a' is negative then the parabola opens down
from the given equation
The value of a=-1 which is negative
so the parabola opens down
Answer:
By using the formula, Parts /whole = percent/100, ⇒ 25/ 50 × 100 = 50%. So, 50 % of 50 is 25 proportion.
