Answer:
Age of teacher = 32 years
Step-by-step explanation:
Average age of 15 students = 16 years
Sum of age of 15 students = 16 * 15 = 240 years
Average of age 15 students and a teacher = 17 years
Sum of age 15 students and a teacher = 17 * 16 = 272 years
Age of teacher = 272 - 240 = 32 years
To solve this question, you need to find how long jump is. For 2m high with <span>1.67 m/s2 it would be:
h= 1/2 gt^2
2= 1/2 * (1.67) t^2
t^2= 1.67
t= 1.29
If the speed is 20 mph and the jump is 2 second, the distance traveled would be:
20 miles/ hour * 1.29 second * (1 hour/3600second)= 0.007179 miles
If you need to convert it to meter then: </span>0.007179 mile * 1609.34meter/ mile= 11.55 meter
Answer:
14/15 meters
Step-by-step explanation:
We add each color of fabric to find the total amount of fabric used.
1/3 +3/5
We need to get a common denominator of 15
1/3 *5/5 = 5/15
3/5*3/3 = 9/15
5/15 + 9/15 = 14/15
4/7 is the simplest form
You can divide 20 by 5 and get 4 and divide 35 by 5 and get 7
