The <em>correct answer</em> is:
B) K’(6, 4); L’(3, 3)
Explanation:
A 270° clockwise rotation maps every point (x, y) to (y, -x). (It negates the x-coordinate and then switches it and the y-coordinate.)
This means the endpoints of the side congruent to KL, K' and L', would be mapped as:
K'(-4, 6)→(6, 4)
L'(-3, 3)→(3, 3)
The answer to the question is 64°
x° + 26°= 90°
x° = 64°
Answer:
$23.98
Step-by-step explanation:
22.50 + 6.6% (1.485) = $23.98
Answer: Todd earned $40 mowing the neighbor's lawn.
Step-by-step explanation:
Let x represent the amount of money that Todd earned, mowing his neighbor's lawn.
He spent one-fourth of his money see a movie. It means that the amount spent in seeing a movie is x/4
Then he spent $6.00 on popcorn and drinks. It means that the total amount spent is
x/4 + 6
The amount left would be
x - (x/4 + 6) = x - x/4 - 6
When he went home, he had $24.00 left. It means that
x - x/4 - 6 = 24
x - x/4 = 24 + 6
x - x/4 = 30
Cross multiplying by 4, it becomes
4x - x = 120
3x = 120
x = 120/3
x = $40
Combinations = n! / (n - r)! r!
In this case:
n = 4
r = 3
Combinations = 4! /(4-3)! 3! = 24/(1)(6) = 24/6 = 4
Answer:
4 arrangements
