Answer:
In 5040 ways.
Step-by-step explanation:
To solve this problem we will use combination without repetition which means:
C ( n k) = (n₁ k₁) (n₂ k₂) (n₃ k₃) = (4 3) (9 2) (7 3) =
(4 · 3 · 2 / 3 · 2 · 1) (9 · 8 / 2 · 1) (7 · 6 · 5 / 3 · 2 · 1) = 4 · 36 · 35 = 5040
It can be done in 5040 ways.
God with you!!!
Answer:
do 800 + 275x 36 in a calculator for ur answer
Step-by-step explanation:
Answer:
Given that in the jar, navy beans and white beans in a ratio of 1:9. Let the amount of navy beans be x.
Then, the amount of white beans in the jar is 9x.
Given that amount of navy beans is x=90
Total amount of beans in the jar is x+9x=10x=10+90=900
So the ratio is 1:9
Step-by-step explanation:
Step-by-step explanation:
Average speed (S) = 200 m/s
Time taken (t) = 2 .5 hours = 2.5 *60*60 = 9000 sec
Now distance travelled (d) = ?
We know
The distance travelled by a body per unit time is
speed so
S = d / t
200 = d / 9000
d = 9000 * 200
d = 1800000 meters.
The plane flies 1800000 meters.
