Answer:
4 and 13
Step-by-step explanation:
You want integer solutions to ...
15 ≤ n(n+1) ≤ 200
If we let the limits be represented by "a", then the equality is represented by ...
n² +n -a = 0
(n² +n +1/4) -a -1/4 = 0
(n +1/2)^2 = (a +1/4)
n = -1/2 + √(a +1/4)
For a=15, we have
n ≥ -1/2 + √15.25 ≈ 3.4 . . . . . minimum n is 4
For a=200, we have
n ≤ -1/2 + √200.25 ≈ 13.7 . . . maximum n is 13
The least and greatest integers on the cards are 4 and 13.
Answer:
Step-by-step explanation:
Points: A, C, E, B, D, F
Line: AB
Line segment: AC, CE, CD, DF, DB
Planes: P, M
Rays: CA, DB
Angles: <ACE=90,< CDF= 90
Parallel lines: line w and line t are parallel to each other
Perpendicular lines: EC is perpendicular to AD and FD is perpendicular to CB
Answer:
0
Step-by-step explanation:
ok so first we have to make those denominators equal
15/21 - 15/21
that pretty much answered your question
15/21 - 5/7 = 0
The answers:
#1 C
#2 H maybe
#3 C
#4 H or J
The Lcm is 104. The lcm of 13 and 8 is the smallest positive integer that divides the numbers 13 and 8 without a remainder. Spelled out, it is the least common multiple of 13 and 8. Here you can find the lcm of 13 and 8, along with a total of three methods for computing it. In addition, we have a calculator you should check out. Not only can it determine the lcm of 13 and 8, but also that of three or more integers including thirteen and eight for example. Keep reading to learn everything about the lcm (13,8) and the terms related to it.
