Answer:
Area = 15.36 ft
Step-by-step explanation:
First find the area of the dotted line triangle using the formula: base x height x 1/2, which would be 1.2ft x 12.8 x 1/2 = 7.68ft.
Next, add another triangle at the top, mirroring the shown triangle, of the parallelogram.
Then, find the area of the shape as though it were a rectangle. (base x height) - 2.4 x 12.8 = 30.72.
Next, multiply the area of the invisible triangle by 2, 7.68 x 2 = 15.36ft
and Finally, subtract the area of the rectangle shape of the the sum of the two invisible triangles, 30.72 - 15.36 = 15.36ft
The area of the parallelogram is 15.36 ft.
Answer:
The mean may not be a fair representation of the date
Step-by-step explain the average is easily influenced by outliers (very small or large values in the data set that are not typical). The median is another way to measure the center of a numerical data set. ... Thus, the median is truly the middle of the data set.
It's an irrational number ... it can never be written down on paper exactly.
The beginning of it is 2.449489... and it keeps going forever.
You might think that using only part of a number in a problem makes your
answer wrong. In a way that's true. But if you use 2.449489 for the square-
root of 6, then your final answer is only about 0.00003 percent wrong, and
that's close enough ... even if you're building bridges or spacecraft.
"But", you say, "How can I hand in an answer on my homework that's wrong ?"
Here's a secret that's so big that nobody ever talks about it. Once you know it,
it'll change your whole way of thinking. And you'll stop fishing for answers on
the internet:
The answers in homework don't matter ! The answer is the least important
part of any homework problem, and nobody needs it. If your teacher needed
an answer, then he/she could get it a lot faster by working out the problem.
If he/she didn't have time to work on it, then the teacher would go to somebody
who knows it cold ... they certainly wouldn't ask somebody who's just learning
it for the first time.
The purpose of the homework is NOT to generate answers. It's to lead you
down the path of learning how to do the problem. When somebody else gives
you the answer and you hand it in, 2 things happen:
#1: you cheat;
#2: you don't learn anything.
It's a bad deal all around.
Answer:
x = 3/4
Step-by-step explanation:
Step 1: Write equation
5x - 2(x + 1) = 1/4
Step 2: Solve for <em>x</em>
- <u>Distribute -2:</u> 5x - 2x - 2 = 1/4
- <u>Combine like terms:</u> 3x - 2 = 1/4
- <u>Add 2 to both sides:</u> 3x = 9/4
- <u>Divide both sides by 3:</u> x = 3/4
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
5(3/4) - 2(3/4 + 1) = 1/4
15/4 - 2(7/4) = 1/4
15/4 - 14/4 = 1/4
1/4 = 1/4
