Answer:
21
Step-by-step explanation:
Given,
Total number of marble except red and green = 3 +3+1
= 7
So, the total number of possible sets of five marbles such that none of them are green or red can be given by
= 21
So, the required number of possible sets are 21.
Answer: 16 1/2
Step-by-step explanation:
It's easiest to multiply improper fractions and then to convert them back into mixed numbers, so 4 1/2 would become 9/2 and 3 2/3 would become 11/3. = 99/6. Now just simplify to 33/2 and then convert back into a mixed number. 16 1/2
Answer:
889.70 feets
Step-by-step explanation:
From the solution diagram attached :
C = 180 - (40 + 45) = 95°
According to the sine rule :
Sin95 / 1950 = Sin40 / b = Sin 45 / a
1950 sin40 / sin 95 = b = 1248.22 ft
1950 sin 45 / sin 95 = a = 1384.13 ft
Sin 40 = h / 1384.13
h = 1384.13 * sin 40
h = 889.70 feets
