Answer:
25.61 ?
Step-by-step explanation:
use Pythagoreans theorem
a^2+b^2=c^2
20^2+16^2=656
sqrt 656=25.61
Answer:
-I haven't done this, but I have copied and pasted from another question and answer from the user syed514:
Graphing is one way to do the problem.But sometimes, graphing it is hard to do.So here’s an algebraic method.
If M(m1, m2) is the midpoint of two points A(x1, y1) and B(x2, y2),then m1 = (x1 + x2)/2 and m2 = (y1 + y2)/2.In other words, the x-coordinate of the midpointis the average of the x-coordinates of the two points,and the y-coordinate of the midpointis the average of the y-coordinates of the two points.
Let B have coordinates (x2, y2) in our problem.Then we have that 6 = (2 + x2)/2 and 8 = (3 + y2)/2.
Solving for the coordinates gives x2 = 10, y2 = 13
C. Typing 210 words in 5 minutes.
Explanation:
42 words per minute is equivalent to 210 words in minutes:
Write the 42 wpm and 210 words in 5 mins as a ratio:
42 : 1 and 210 : 5
Multiply both sides in the ratio 42 : 1 by 5:
42 x 5 = 210
1 x 5 = 5
= 210 : 5
Therefore 210 words in 5 mins is an example of the unit rate 42 wom because it is equivalent.
Hope this helps!
