If you're using a coordinate plane, I think it makes a trapezoid
Answer: 2 inches, 3 inches, or 3.125 and 2.083
Explanations:
The simplest way is to take 20% of the 2.5 inches and go that much above & below 2.5 inches.
2.5 x 20% = 2.5 x 0.20 = 0.5
So 2.5 - 0.5 = 2 inches was predicted
And 2.5 + 0.5 = 3 inches was predicted.
The more complicated way is to see number + 20% of that number = 2.5, and what number - 20% = 2.5.
Which solution sounds more like what you’re doing in class right now?
If it’s the more complicated way:
0.8x = 2.5 (80% of the predicted rain value equals 2.5)
x = 3.125 inches was predicted
1.2x = 2.5 (120% of the predicted rain value equals 2.5)
x = 2.083 inches was predicted
Sorry, this is probably confusing. Let me know what questions you have.
Answer:
sin -115 = -0.91, cos -115 = -0.42
Step-by-step explanation:
Answer:
<h2>1).</h2>
(5a3b)(2ab)
Expand
That's
15ab( 2ab )
we have the answer as
<h3>30a²b²</h3>
<h2>2).</h2>
5y(-y² + 7y - 2)

That's
<h3>- 5y³ + 35y² - 10y</h3>
