A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc.
The opposite inner angles equal the outer one
(3x+5) = 2x + 30
x = 25
(3*25)+5
TSQ = 80
1. Do NOT stress! Just relax, it will be fine.
2. Make a list of things you have not mastered yet.
3. In your list, just go over one thing at a time (in your math, reading, science, social studies book)
4. Take it slowly, but pace yourself to when your testing is.
5. After you have studied these things, just look over them one more time.
6. Take the test.
7. Relax in the test... if you don't know a question just skip it.
8. Come back to the problems you skipped.
9. Narrow down the answer choices.
10. Succeed
I hope this helps! Good Luck on your test!
Answer:
166 mm²
Step-by-step explanation:
The area is given by ...
A = (1/2)Pa . . . . . where P is the perimeter and "a" is the apothem
One side of a 6-sided figure is shown as 8 mm, so the perimeter is ...
P = 6·(8 mm) = 48 mm
Filling in the apothem value, we have ...
A = (1/2)(48 mm)(4√3 mm) = 96√3 mm² ≈ 166 mm²
The area of the hexagon is about 166 mm².
Answer: B) 160
<u>Step-by-step explanation:</u>
Since the Standard deviation of 21 bins is 3 bins, then the first 7 bins falls in the first 2.5% edge of the bell curve.
2.5% of 21 times 1000 = (0.025)(21)(1000) = 160
