Answer:
The answer is 6.3
Step-by-step explanation:
True.
The Pythagorean theorem is a^2 + b^2 = c^2 where a^2 and b^2 are the two legs of the triangle (two sides connected by the right angle) and c is the hypotenuse (longest side, opposite the right angle).
To solve using the Pythagorean theorem, plug in sides AC and CB into a and b, then solve for c.
23^2 + 31^2 = c^2
529 + 961 = c^2
c^2 = 1490
c = √1490 = 38.601

14/20 21/30 28/40 are the equivalent fractions
Answer:
Step-by-step explanation:
The formula you wrote has the fraction the other way around. You can find that the range of a projectile is in reality approximated by the equation 
, where we will use ft for distances.
From the given equation we have then 
, which means 
since the arcsin is the inverse function of the sin.
Since we have x = 170 ft and v = 85 ft/s, we can substitute these values from the equation written, and we will have 
, and from now on we have just to use a calculator, obtaining 
Answer:
$299
Step-by-step explanation:
Make a proportion
He makes $184 for 8 hours of work, and $x for 13 hours of work
184/8=x/13
To solve, we need to get x by itself. To do this, multiply both sides by 13. We multiply because x is being divide by 13, and we want to do the opposite.
13(184/8)=(x/13)13
The 13s on the right will cancel, leaving us with
13(23)=x
299=x
So, he will earn $299 for 13 hours of work.
