Alicia is making cupcakes for a party she is having and wants to make sure everyone gets at least 1 cupcake The recipe calls for 1/2 teaspoon of salt for every batch and each batch makes 21 cupcakes if the part will have a total of 84 people attending how many teaspoon of salt will Alicia need.
Answers
2 teaspoons
21+21=42 so for every 1 teaspoon there is 42 people
42+42=84 so it’s 2 teaspoons
Answer:
Let's imagine that x is the number of teaspoon of salt needed to make at least 84 cupcakes.
So we know that, 1 batch makes 21 cupcakes, and we need at least 84 cupcakes, so the number of cupcakes batch needed here should be:
84 ÷ 21 = 4 (batches)
Since we knew the number of batches that we need to make the cupcakes, we now calculate the amount of sugar needed. We have:
1/2 teaspoon of salt for every 1 batch.
x teaspoon of salt for every 4 batches.
x = (4 . 1/2) . 1 = 2 (teaspoons)

First, create some variables.
w = width
l = length
Then you know that the length is 3 times the width, so
l = 3w
The equation for perimeter is
P = 2(l+w)
Now you use substitution, substituting the 3w for l because you found that earlier.
P = 2((3w) + w)
And simplify.
P = 2(4w)
P = 8w
And you know P = 30 because they told you that.
30 = 8w
w = 15/4 inches, or 3.75 inches
Now substitute that value back into that first equation,
l = 3w
l = 3(15/4)
l = 45/4 inches, or 11.25 inches.
The dimensions are 11.25in for length and 3.75in for width.

The volleyball problem:
100 minutes of stretching and scrimmaging combined, and you know 10 have to be stretching, so 90 is scrimmaging.
s = scrimmaging
T = total time
s = 2/3T (they gave you this)
90 = 2/3T
T = (90*3)/2
T = 270/2
T = 135 minutes, or 2 hours and 15 minutes.
