Answer:
1080 degrees
Step-by-step explanation:
A regular octagon has 135 degrees per interior angle. To find the sum, add 135 for each angle. There are 8 interior angles.
8*135 = 1,080
we have
--------> equation 
let's change of variable
--------> equation 
substitute in the equation in equation
therefore
<u>the answer is</u>
If the boat can travel 45 mph in still water and the current is 10 mph, down stream, or with the current, has the boat moving at 55. Upstream has the boat moving 35 mph. It took t time to go with the current and an hour longer, t + 1, to go against it. Going from point A to B and back to A again means that the trip there was the same distance as the trip back. So d is the same for both upstream and downstream. The equation for upstream is d = 35(t + 1) or d = 35t + 35; the equation for downstream is d = 55t. Since the distances are the same, the transitive property says that so are the rates and times; therefore, we can set those equal to one another. 35t + 35 = 55t. Solve for t. When we find that t = 7/4 (1 3/4 hours), we sub that in to solve for distance. 55(7/4) = 96 1/4 miles.
Answer:
Answer is 3/4
Step-by-step explanation:
Edward can distrubute pearls to 2 identical bags as fallows:
- 2W for one bag and 2B for another bag. In this scenerio the probability of picking a black pearl is 1/2.
- 1W and 1B for one bag and 1W and 1B for another bag. In this situation the probability of picking a black pearl is 1/2 × 1/2 is equal to 1/4
- At the end, the sum of two scenerio is 1/2 + 1/4 = 3/4
