The answer would be C. We know that d is equal to the initial depth of a lake. The two given initial depths are 58 feet and 53 feet, so we know that one of the equations must be either d=58 or d=53. Because there only C has either one of those, d=58, we know that it must be the answer.
To find the other equation, it is just a linear function for the other lake. The y-intercept, or initial value, is 53, so in the equation y=mx+b, it is the b value. The slope, or m value, is 3 feet, so you have y=d=3x+53.
Answer:
6 days
Step-by-step explanation
2/3 cups x 3 days = 2 cups
2 cups x 2 cups = 4 cups
4 cups = 6 days
Answer:
Step-by-step explanation:
Given
Required
Solve (a) to (d)
Using tan formula, we have:
This gives:
Rewrite as:
Using a unit ratio;
Using Pythagoras theorem, we have:
Take square roots of both sides
So, we have:
Solving (a):
This is calculated as:
Where:
So:
Solving (b):
This is calculated as:
Where:
---- given
So:
Solving (c):
In trigonometry:
Hence:
Solving (d):
This is calculated as:
Where:
So:
160oz. This is because, knowing that there are 16oz in one pound, you can multiply 16 by how many pounds you have to get the oz measurement. In this problem, we multiplied 16 by 10, getting 160oz.
they amount of money are not the same
reason why;
the reason why its not the same is because 2x8x9=144 and 3x9x12=324 and the amount of money spent is different
