Answer:
step 2
Step-by-step explanation:
from -8(a+6) to -80 - 48 is incorrect
when you multiply -8 x a it's -8a not -80
Answer:
(Measure ) L+W : 11 and 8 inches.
These L + W measures are of each triangle and when either halved as proven below will show (A): 44inch^2
Step-by-step explanation:
Two congruent triangles of 44 sq inch = base 8 height 11
or base 11 height 8
Finding that both numbers find the same area.
Note for future areas either measure for triangle base + height
8 x 11 or 11 x 8 = 88 when halved its the same answer.
where 7 x 10 = 35
13 x 10 = 65
and so on;
No other number multiplies its length and height to show 44
Answer:
Yes
Step-by-step explanation:
Any number with a 0 at the back is divisible by 10
We are told that every 9th person gets free popcorn and every 6th person gets free apple juice at the movie theater. We want to show if the 36th person is the first to get both free popcorn and apple juice.
Since every 9th gets free popcorn, then the 9th and 18th and 27th and 36th people get it. We can use numbers and show this as multiples of 9.
9, 18, 27, 36, 45, 54, ...
And we repeat it for every 6th and the free juice.
6, 12, 18, 24, 30, 36,....
Shani thinks 36 comes first, and she's wrong. 18 appears on the list before 36 as something that's common. What are we finding is the lowest common muliple of 6 and 9.
6 = 2 x 3
9 = 3 x 3
The lowest common multiple will have a 2, a 3, and a second 3 (because we don't double count). 2 x 3 x 3 = 18. This matches up to the list of multiples.
Thus, Shani is wrong that the 36th person gets both free items, as she did not account for the 18th person gettting both free items
