Answer:
Depends on amount of students.
Step-by-step explanation:
You would just multiply the amount of students time (1 1/2) = (1.5)
Ex:
3 students 4 1/2 hours
4 students 6 hours
5 students 7 1/2 hours
and so on
Answer:
y-2=1/3(x+3)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-2)/(3-(-3))
m=2/(3+3)
m=2/6
simplify
m=1/3
y-y1=m(x-x1)
y-2=1/3(x-(-3))
y-2=1/3(x+3)
To find their average miles per hour we can divide the total miles by the hour used:
4 2/3 ÷ 1 2/3
=4x3+2/3 ÷ 1x3+2/3
=14/3 ÷ 5/3
In division, when we switch the place of numerator and denominator, we can change it to multiplication which makes the calculation easier as we can factorize the numbers.
=14/3 x 3/5
Factorize 3 in both amounts:
=14/1 x 5/1
=14/5
=2.8 miles/hour
Therefore their average speed is 2.8 miles/hour.
Hope it helps!
Step-by-step explanation:
Area is 12*5=60
Height is 4
Perimeter is 2*17=34
Surface area=120+136=256
