Look at the prime factorization. If all the factors have powers that are multiples of 6, then the number is a square and a cube. If they are multiples of 3, then a cube; if multiples of 2, then a square.
1000 = 2³·5³ . . . . a perfect cube
4 = 2² . . . . a perfect square
120 = 2³·3·5 . . . . none of the above (not a square or a cube)
36 = 2²·3² . . . . a perfect square
100 = 2²·5² . . . . a perfect square
49 = 7² . . . . a perfect square
125 = 5³ . . . . a perfect cube
25 = 5² . . . . a perfect square
Answer:
The answer to your question is letter C
Step-by-step explanation:
Process
1.- Find two points of the line
A ( 0, 1)
B ( 1, -3)
2.- Find the slope of the line
m = -4
3.- Find the equation of the line
y - y1 = m (x - x1)
y - 1 = -4( x - 0)
y -1 = -4x
y = -4x + 1
Answer:
Probability that both of them use it = 0.3945
Step-by-step explanation:
Given:
Student use app = 63%
Number of chosen student = 2
Computation:
Assume total number of student = 100%
So, probability that both of them use it.
⁶³C₂ / ¹⁰⁰C₂
Therefore, probability that both of them use it = 0.3945
Answer:
The monthly rent of the complex = $ 650
and $450 is the security deposit.
Step-by-step explanation:
The amount paid for first month's rent = $1100
Now, let the monthly rent of the complex = $K
So, Deposit on the monthly rent = $ ( K - 200)
Now, according to the question:
$K + $ ( K - 200) = $1100
or, 2K = 1100 + 200
or, K = 1300/2 = 650
or, K = $ 650
Hence, The monthly rent of the complex = $ 650
and the deposit of the rent = K -200 = 650 - 200 = $450
