7. Straight lines are also = to 180°
If you look at the diagram, when you add the two angles together, they form a straight line.
Since the angles add up to 180°, you can do:
(x + 25)° + (4x + 5)° = 180°
x + 25 + 4x + 5 = 180 Combine like terms
5x + 30 = 180 Subtract 30 on both sides
5x = 150 Divide 5 on both sides
x = 30
Combined in mathematics is to add together to find a total. If you combine 1 and 2 you get 3.
Force = mass x exceleration
1100 x 0.5 = 550
We are given with the expression <span>tan2x / x</span> and asked to evaluate the expression to limit as theta approaches zero. In this case, we substitute first zero. The answer is zero over zero. This is indeterminate so we derive the terms accdg to L'hopital's rule. The derivative is 2 sec^2 2x/1. cos 2x is 1 so is sec^2 2x. Hence the answer is 2.
Answer:
the Bision is 10 miles / hour faster if he could keep it up
Step-by-step explanation:
There are 60 minutes in an hour.
Therefore the bison can run [3520 feet / min] * [60 min ] =211288 feet in an hour.
Now you have to convert 212200 to miles. Do this by dividing by 5280
212200/5280 = 40 miles.
Kind of hard to believe isn't it. 40 miles is a long way when you are running it.
The bison is faster by 10 miles / hour.
This can be done all in 1 step if you know how to do dimensional analysis
3520 feet / minute * [ 60 min/ hour ] * [ 1 mile / 5280 feet] = 40 miles
