-- Start with 86.
-- Subtract 9 the first time. You have 77 left.
-- Subtract 9 the 2nd time. You have 68 left.
-- Subtract 9 the 3rd time. You have 59 left.
-- Subtract 9 the 4th time. You have 50 left.
-- Subtract 9 the 5th time. You have 41 left.
-- Subtract 9 the 6th time. You have 32 left.
-- Subtract 9 the 7th time. You have 23 left.
-- Subtract 9 the 8th time. You have 14 left.
-- Subtract 9 the 9th time. You only have 5 left, so you can't subtract 9 again.
You subtracted it 9 times, and you have 5 left.
So 86 divided by 9 is (9 with remainder 5) .
<u>Answer:</u>
Supplement of 84° is 96°
Complement of 54° is 36°
<u>Step-by-step explanation:</u>
1<u>) A supplementary angle is two angles that add up to 180°</u>
so to find the supplement of 84° ⇒ 180°- 84° = 96°
2) <u>A complementary angle is two angles that add up to 90°</u>
so to find the complement of 54° ⇒ 90°- 54° = 36°

Answer:
133.06 miles per hour
Step-by-step explanation:
Distance =2438.9 miles
Time=18 hours 20 minutes.
First we convert the time to hour
60 minutes = 1 hour
20 minutes=(20/60) hour=0.33
Therefore her time=18+0.33 hour=18.33hour
We are to determine the average speed of her flight in miles per hour.
rate=distance/time
=2438.9/18.33
=133.06 miles per hour
Her average speed is 133.06 miles per hour
-21, -23, -27, -28, -28, -29 order them least to greatest and then find the middle if there is not a middle then put -27.5 as your answer for the median. For the mean add up all the number then you should get -156 then divide it by 6 which should give you -26 for the mean. and for the mode you should get -28 as the one that occurs the most often.
mean: -26
median: -27.5
mode: -28
