Given:
In an asteroid field, 75% of the asteroids are carbonaceous asteroids.
There are 375,000 carbonaceous asteroids in the asteroid field.
To find:
The number of asteroids that are not carbonaceous.
Solution:
Let the total number of asteroids be x.
According to question,
Divide both sides by 0.75.
Asteroids not carbonaceous = Total asteroids - Carbonaceous asteroids
Therefore, 125,000 asteroids are not carbonaceous.
Answer:
B 32
Step-by-step explanation:
sqrt(71*x)
71 is prime
sqrt(71) sqrt(x)
A. 19 prime
B. 32 = 16*2 16 is a perfect square
C. 34 = 2*17 both of which are prime
D. 41 prime
sqrt(71) sqrt(16 *2) = sqrt(71) * sqrt(16) * sqrt(2) = sqrt(71)*4*sqrt(2)
=4sqrt(142)
Answer:
3 times
Step-by-step explanation:
Given
18-white socks
18 blue socks
36 socks total
First time reached in,
18/36 ( =1/2=(50%)) chance of getting a white sock, 18/36 (=1/2=(50%)) chance of getting a blue sock
assuming you got a white sock,
17-white socks
18-blue socks
35 socks left in
Second time reached in,
17/35 (<1/2=(50%)) chance of getting a white sock, 18/35 (>1/2=(50%)) chance of getting a blue sock
You would be more likely to get a blue sock, assuming you did,
17-white socks
17-blue socks
34 socks left
Third time reached in,
17/34(=1/2=(50%)) chance of getting a white sock, 17/43(=1/2(50%)) chance of getting a blue sock
Regardless of what sock is picked you would have a matching pair of socks in hand
The value of 12/24 is equals to 0.5.
