Answer:
31.4cm
Step-by-step explanation:
C = 2π.r = 2×3.14×5 =3.14×10 = 31.4
2,160/150 = 14.4
The diameter is 14.4 inches.
Step-by-step explanation:
using Pythagoras a²+b²=c²
13²+16²
169+256=425
square root of 425 is 20.6 which round to 21 miles
Answer:
The probability that a student buys a drink is 0.47
Step-by-step explanation:
The probability that a student buys a drink will be given by;
( the number of students who bought a drink)/(the total number of students)
We are told that;
Of the 100 students who came to the movie, 62 bought popcorn and 47 bought a drink. Therefore, the required probability is;
47/100= 0.47
First you can change the mixed fraction (1 3/4) into an improper fraction. First you add the whole number add the nominator and then multiply what you get by the denominator. So 1+3=4, 4x4=16. Then we have 16/4 which simplifies to 4. Now we can add everything else because they all have common denominators (2/1, 4/1, 10/1). So 2+4=6. 6+10= 16.
The final answer is 16 pounds.
