How many pieces of gum are in 4 packages of gum?"
Using a proportional function, there are 60 pieces of gum in 4 packages.
<h3>What is a proportional relationship?</h3>
Two values x and y are said to be in a proportional relationship if x=ky, where x and y are variables and k is a constant.
The constant k is called constant of proportionality.
The constant is given by:
k = 15/1
k = 30/2
k = 45/3
k = 15.
Therefore, the number of pieces of gums in x packages is given by:
y = 15x.
In 4 packages:
y = 15 x 4
y = 60 pieces of gum.
Using a proportional function, there are 60 pieces of gum in 4 packages.

Answer:
$60
Step-by-step explanation:
Let the company's fixed charge be "x"
And let the the hourly rate be "h"
Firstly, 2 hours + fixed = $110, we can write:
2h + x = 110
Next, 3 hours + fixed = $150, we can write:
3h + x = 150
We multiply the first equation by "-1" to get:
-1 * [2h + x = 110] = -2h - x = -110
Now we add this equation to the 2nd:
3h + x = 150
-2h - x = -110
-------------------
h = 40
Hence, the hourly rate is $40
So, it would cost 1.5 * 40 = $60 for 1.5 hours
Answer:
Total number of ways are 336.
Step-by-step explanation:
It is required to find the number of ways in which we can award a 1st, 2nd and 3rd place prize among eight contestants. It means we need to find the number of permutations. We need to find .
Here, r = 3
So,
So, there are 336 ways.
0.1 milligrams is 0.0001 grams, so the mass should be recorded to the same accuracy,
5.0000 grams or 5000.0 milligrams
