Answer:
Read answer below :)
Step-by-step explanation:
So you know that it takes 90 seconds for 10 gallons, right? So you know it's 9 seconds per gallon, removing the 0's (which is the easiest way to simplify).
then you take 8 divided by 60 to find out how long it takes for one gallon.
My math shows this:
A = 9 seconds per 1 gallon
B = 7.5 seconds per 1 gallon
60 seconds for 8 gallons, 30 seconds for 4 gallons, 15 seconds for 2 gallons, 7.5 seconds for 1 gallon. (Notice how I divided by two each time until it was simplified)
The inside angles of a 5 sided figure needs to equal 540 degrees.
The total of the given angles is: 131 + 108 + 107 + 110 = 456.
Subtract the total from 540 for x.
X = 540 - 456 = 84 degrees.
Y would equal 6.16.
We can use trigonometry and label AC as the hypotenuse and BC as the adjacent side.
This means we have to use the cosine ratio, cos = Adjacent/hypotenuse, and so to find the adjacent we must do cos(44.25) × 8.6, which is 6.16.
I hope this helps!
Answer:
267mph or 268mph
Step-by-step explanation:
Well the exact answer is about 267.8 so depending on if you round up or down there are two answers.
1km = 0.62137119mi
So 431 • 0.62137119 = 267.8
