Answer: 8 adults
Step-by-step explanation:
Number of students = 30
Adults accompanying the students are to drive:
Each car can accommodate 5 passengers including the driver. That is, 4 students and the driver.
In other to get the 30 students to Washington :
Number of cars / adults = (Total students / number of students each car can accommodate)
= 30 / 4
= 7. 50
= 8 (to the nearest whole number)
The smallest number of adults that should be invited for the trip will 8 since they will be the one's to drive the students.
Step-by-step explanation:
the AB or hypotenuse seems to be 47.5
Angle at point A = 180 - 90 - 40 = 50 degrees
To find 2 remaining lengths of sides of triangle we just need to use basic trigonometry.
cos40 = 10/AC => AC = 10/cos40 = 13.05
tan40 = AB/10 => AB = 10*tan40 = 8.39
If we want to check this we can use Pythagoras theorem:
AB^2 + BC^2 = AC^2 and see that lengths that we calculated are correct.
Answer:
part 1) It takes 2/15 hour to complete 1 task
Part 2) The robot can only complete 7 tasks in an hour (the remaining doens’t count)
Step-by-step explanation:
So first divide to find unit rate
2/5 ÷ 3
2/5 * 1/3
2/15
For part 2
Just put the unit rate in an equation
2/15x=1
Where 1 is the single hour and x is the task
solve
you’ll get 7 1/2
Due to only requesting for tasks in an Hour
its only 7 task
