Ur not dumb I’m the dumb one XD
Well, with the equation in that form, it may not be obvious how to graph it.
So let's change just the form a little bit... without changing the equation:
<u> y - 5 = 0</u>
Add 5 to each side: <em>y = 5 </em>
Look at that for awhile, and think about what it tells us.
It says that 'y' doesn't depend on 'x' at all. No matter how far left or right
you go on the graph, the y-value of <em>every point</em> is 5 .
The graph is a horizontal line across the graph. It cuts across the y-axis at
the point where y=5 , and it stays exactly at that same height everywhere.
Answer: C. 4 hours
Explanation: You first measure how long 1/5 of an hour is in which is 12 minutes. You then multiply 12 by 20 because it takes 12 minutes to get 1/20 of the lawn watered. Your answer now should be 240. Finally, divide that number by 60 because you are measuring time in hours. Your final answer should be 4 hours.
Answer:
the answer is C: 1932 sq. cm
Step-by-step explanation:
You want to break down the sections (which is double for each)
there are 6 rectangles but you will only need to calculate for 3
1st rectangle
a = (25) (12)
a = 300 sq. cm
**then multiply by 2 = 600 sq. cm**
2nd rectangle
a = (12) (18)
a = 216 sq. cm
then 216 * 2 = 432 sq. cm
3rd rectangle
a = (25) (18)
a = 450 sq. cm
then 450 * 2 = 900 sq. cm
Total Surface Area
SA = 600 sq. cm + 432 sq. cm + 900 sq. cm
SA = 1932 sq. cm
