$23.58 divided by 12 = $1.965
Each roll is about $1.97 (if you round up)
2/5 tablespoons of vanilla extract ... 6 muffins
x tablespoons of vanilla extract = ? ... 18 muffins
If you would like to know how much vanilla extract does he need, you can calculate this using the following steps:
x * 6 = 18 * 2/5
x * 6 = 36/5 /6
x = 36/5 / 6
x = 6/5 = 1 1/5
Result: Arthur will need 1 1/5 tablespoons of vanilla extract for 18 muffins.
Answer:
Step-by-step explanation:
Investment = $5,000
Annual Interest = 5%
5000/100 x 5/1
50×5 = 250
First year interest = $250
Therefore, 250 x 20
= $5,000
It will take him 40 years.
now, for a rational expression, the domain, or "values that x can safely take", applies to the denominator NOT becoming 0, because if the denominator is 0, then the rational turns to
undefined.
now, what value of "x" makes this denominator turn to 0, let's check by setting it to 0 then.
so, the domain is all real numbers EXCEPT that one.
The first one is congruent because it is just turned 120degrees
