Step-by-step explanation:
1. Arrange all the numbers in ascending order.
2. Since there are 10 numbers, there will be 2 numbers in the middle, add those two middle numbers and divide by 2.
3. The result is your answer.
Since the angles are supplementary, we know that they must add up to equal 180 degrees by the definition of supplementary angles
set the sum of the 2 angles to equal 180 and solve for x
6x + 48 + 60 = 180
6x + 108 = 180
6x = 72
x = 12
you could check to make sure that your x value is correct by plugging it back into the equation
6(12) + 48 + 60 = 180
72 + 48 + 60 = 180
120 + 60 = 180
180= 180
hope this helped!
A and D
should be the answers.
Okay, to find the ratio, add up all the numbers of DVDs.
You should end up with 36 DVDs.
The question states that you need to find the ratio between the action DVDs and the total amount of DVDs.
The amount of action DVDs is 12.
Now take 32 and 12, the ratio of the action DVDs and the total amount of DVDs to get your ratio.
The ratio is 12 out of 31, or 12:32
Answer:
About 5 hr 10 min
Step-by-step explanation:
rate 1 = 1 pool / 9 hrs rate 2 = 1 pool / 12 hours
now find the time with both rates combined
1 pool / ( 1/9 + 1/12) = 1/ (7/36) = 36/7 hr = 5 1/7 hr = 5 hr 8.6 min
