Answer:
A
Step-by-step explanation:
A. (1,3) and (6,3) have the same y-coordinate, so the distance between them is the difference of the x-coordinates.
distance = 6-1 = 5
:::::
B. (3,5) and (1,5). Again, the same y-coordinate. Distance = 3-1 = 2 ≠ 5
:::::
C. distance = 5-1 = 4 ≠ 5
:::::
D. distance = 3-2 = 1 ≠ 5
Answer:
80 blue
Step-by-step explanation:
r=red
b=blue
4b+2r=6 lights in one light cluster
120/6=20 clusters
20 clusters of 4 blue lights =80
Given parameters:
First sets of staircase = 
Next sets =
Third sets = 
Unknown:
The least possible number of steps =?
Solution:
The least possible number of steps will be the lowest common multiples of these sets of steps.
We want fractions that will give whole numbers because realistically, one cannot take half a step of a step.
So, the number of steps must be a multiple of denominators of the fractions given.
Denominators are 2 , 3 and 8
Their least common multiple is 24;
This the lowest number by which 2, 3 and 8 can all divide.
So, the least number is 24 steps
First of all the repeated digits numbers are 66,77 and 99 Total 3
Numbers beginning with 6 Total 3 (63,67 and 69).
Numbers begin with 7 Total3
and begin with 9 Total 3.
answer is 12
A = (1/2)(8yd)(15yd) = 60 yd²
