Answer:
#1 (4b + 6a) #2 150y
Step-by-step explanation:
#1 :area of right triangle: ab/2
4x2/2 = 4b
area of rectangle: length x width
2 x 3 = 6a
#2:
5y + 2.5y = 7.5y x 2 = 15y
so the top and bottom are both 15 y
the sides are each 5y so thats 10 y
15x10= 150y

Step-by-step explanation:
Hey, There i hope you are haveing a great day :) So I look at the example so it should be the same I think like how you work out the mean by adding all the numbers and then diving them so, (8 + 4 + 8 + 8 + 10 + 2 + 4 + 4) = 48 and now you know you have got 8 numbers there a divide them so 48/8 = 6. and then I think you take away it so, 8 - 6 = 2 4 - 6 =-2 8 - 6 = 2 8 - 6 = 2 10 - 6 = 4 2 - 6 = -4 4 - 6 = -2 4 - 6 = -2 and then 2 + -2 + 2 + 2 + 4 + -4 + -2 + -2 divide 8 = 0 and you can't divide anything by 0 so that would be the answer.
D = r*t
100meters = r*11
100/11 = r
9 ≈ r
9 about meters a second
