Answer:
r ≈ 6
Step-by-step explanation:
r= <u>414.78</u>
π x 11
≈ 5.99848
Because of this, the answer is rounded up to 6, but the exact answer is about 5.99848
Compatible numbers are number that are easy to add together.
If I change 87 to 90 and 34 to 30 I have compatible numbers
90 + 30 = 120. I would probably just change the 87 to 90 since I could to 90 + 34 mentally and get 124 which is closer to the exact answer.
222 + 203 - becomes 220 +200 = 420
May I suggest that you can also balance the numbers: when you change 87 to 90 you added 3. To compensate, subtract 3 from 34 and get 31. 90+31= 121, the exact answer.
222 becomes 200 so you lowered it by two. To compensate add 2 to 203. Now you have 220+205= 425 which again, is the exact answer. Use estimation is needed but what I just showed you works well to and give you the exact answer.
One more: 199 + 306 = 200 + 305 = 505 (exactly) Instead of 200 + 300 = 500 which is a close estimate using compatible numbers.
Answer:
Option (A).
Step-by-step explanation:
Statements Reasons
1). Draw a line ZY parallel to PQ 1).Construction
2). m∠ZRP + m∠PRQ + m∠QRY = 180° 2). Angle addition postulate
3). ∠ZRP ≅ ∠RPQ 3). Alternate interior angles theorem
4). ∠QRY ≅ ∠PQR 4). Alternate angle theorem
5). m∠RPQ + m∠PRQ + m∠PQR =m∠ZRY 5). Substitution
6). m∠ZRY = 180° 6). Definition of supplementary angles
7). m∠RPQ+m∠PRQ+m∠PQR = 180° 7). Substitution
Here reason of statement (6) is incorrect.
m∠ZRY = 180°, because angle ZRY is a straight angle not a supplementary angle.
Therefore, Option (A) will be the answer.
Answer:
13 hours and 12 minutes
Step-by-step explanation:
you put 3.25 as a fraction which is 3 1/4. then I took 3 1/4 and misused it by 11 1/2. 23/2 - 13/4 = 8 1/4
then we took the 5/8 and divided it by 33/4 (3 1/4)
I got 13 1/5.
13 1/5 is 13 hours and 12 minutes.
