Answer:
2. congruent
3. congruent
Step-by-step explanation:
Segments will be congruent if their lengths are the same. Their lengths will be the same if the sum of squares of the x- and y-differences of their endpoint coordinates are the same.
2. B-A = (-4-(-4), 8-1) = (0, 7)
D-C = (5-(-2), -5-(-5)) = (7, 0)
The total of 0² and 7² is the same as the total of 7² and 0², so these segments are congruent. (They are both of length 7.)
__
3. B-A = (2-4, 6-1) = (-2, 5)
D-C = (-4-(-2), -3-2) = (-2, -5)
The sum of (-2)² and 5² is the same as the sum of (-2)² and (-5)², so these segments are congruent. (They both are of length √29.)
The answer would be j=61 in order to make the equation true
Answer:
First of all, lateral means the sides of the can in this case.
Calculate the surface area of the can, subtract the area of the top and bottom which are two circles, and theres the answer!
Step-by-step explanation:
1. SA= 2πrh+2πr^2
= 2(π)(1.3)(4) + 2(π)(1.3^2)
= 43.29- (π1.3^2)^2
=15.09
Please note that ^(a number) means to the power of (that number). Hope this helps!
Mary used 8 apples!!
24 divided into 6 is 4, then you times that by 2
These are the answers I got for these questions. B, B, A, A, B, B, B, A, D, and D. I suspect that most of those questions are missing division signs. These answers should be correct.
