Answer:
mAOB = 139 degrees
Step-by-step explanation:
1) By supplementary angles, you can set up the equation:
mAOB + mBOC = mAOC = 180
8x + 51 + (6x - 25) = 180
2) Solve for x:
14x + 26 = 180
14x = 154
x = 11
3) Substitute x into 8x + 51 to get mAOB:
8(11) + 51
=88 + 51
=139
Answer:
Given: Population of ducks in lake, last year is 60.
Also, the population of ducks this year decreased by 1/4 th over the last year.
So, the population of ducks this year is = 60*(1-1/4)
= 60*(3/4)
= 45
Therefore, the population of ducks this year is 45 ducks.
Well there are 5280 feet in 1 mile and if you multiply that by 2 then that's too many. if you multiply 5280 by 1.5, then you get 7920 so it is equal to 1.5 miles.
There are 36 inches in 1 yard so you multiply 6 by 36 to get 216.
Again there are 5,280 feet in 1 mile. Divide 26,400 by 5,280 and you get 50 miles.
12 inches in 1 foot. Multiply 12 by 9 and get 144.
22 feet equals 7 yards and 1 foot.
51 inches equals 4 feet and 3 inches. (4 feet equals 48 inches)
Btw, 7 yards is greater then 20 feet (7 yards equals 21 feet)
2 miles is more then 3,500 yards. (2 miles equals 2,520 yards)
11.5 feet is less then 4 yards (4 yards equals 12 feet)
72 inches is EQUAL to 2 yards
5.5 yards is more then 192 inches. (5.5 yards equals 198 inches)
Answer:
the answer is 52
Step-by-step explanation:
you have to divide 468 by 9 and should get you too 52
