Answer:
Step-by-step explanation:
To make an improper fraction, make the whole number into a fraction with the denominator 6. We do this because we want the fraction and the whole number to have the same denominator, so we can later add them together.
To do this, multiply 4 by 6:
*
=
Then, add and

Answer:
The depth of snow at 9:00 am was 19 inches.
Step-by-step explanation:
Consider the provided information.
Let x represents the number of hours and S(x) represents the depth of snow.
There was no snow on the ground when it started falling at midnight at a constant rate of 1.5 inches per.
That means the depth of snow will be:
At 4:00 a.m., it starting falling at a constant rate of 3 inches per hour,
7:00 a.m. to 9:00 a.m., snow was falling at a constant rate of 2 inches per hour.
The required piece-wise linear function is
We need to find the how deep was the snow at 9:00 am
For 9:00 am we will choose the function which can take the value of x=9
Substitute the value of x=9 in
Hence, the depth of snow at 9:00 am was 19 inches.
The least number of boxes Sharon should buy is 5 boxes.
Step-by-step explanation:
Given,
Number of cards in box = 12
Number of stamps in packages = 20
We will find least common multiple of 12 and 20.
12 = 12,24,36,48,60,.....
20 = 20,40,60,80,....
The LCM of 12 and 20 is 60.
Now,
12 cards = 1 box
60 cards =
60 cards = 5 boxes
The least number of boxes Sharon should buy is 5 boxes.
