Answer:
First we must learn to dissect a question.
<h3>Explanation:</h3>
Part 1
We can list our facts first:
- Every 2 dozen cookies takes 1.5 teaspoons of cinnamon to make
- She needs 13 dozen cookies
She needs 13 dozen cookies. So (13/2)x 1.5 teaspoons
<h3>Part 2</h3>
She needs 9.75 teaspoons and 3 teaspoons make a tablespoon
So..
Answer:
(x) = 
Step-by-step explanation:
let y = f(x) , then rearrange making x the subject
y = 6x + 7 ( subtract 7 from both sides )
y - 7 = 6x ( divide both sides by 6 )
= x
Change y back into terms of x with x = (x) , then
(x) =

Answer:
15 cm
Step-by-step explanation:
The formula for the surface area of the cone is ...
A = πr² +πrL = πr(r +L)
The radius of this cone is half its diameter so is (12 cm)/2 = 6 cm. Then the slant height L can be found from ...
126π cm² = π(6 cm)(6 cm +L)
21 cm = 6 cm +L . . . . . . . . . . . . . . divide by 6π cm
15 cm = L . . . . . . . . . . . . . . . . subtract 6 cm
The slant height is 15 centimeters.
