Answer:
128 cm^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2) h
where b1 and b2 are the lengths of the bases and h is the height
A =1/2( 10+22) * 8
A = 1/2 (32)8
= 128
4/5 divided by 1/10 = 4/5 x 10/1 = 40/5 = 8
First round 15.25 to 15.30 and round 4.85 to 4.90 and then add you get 21.20 no it is not reasonable and you round to the decimal ones
The answer is 9 because the difference in this sequence goes +1,+2,+3 etc. So all you have to do is plus 6 to 15 and you get 9.
Answer:
instead of just pointing out the highest speed or one speed, list all the different speeds or increasing/decreasing and the different intervals
ie for minutes 2 to 3, her speed was 30 mph . . . from minutes 6 to 8, her speed was decreasing at a constant rate of -2 mph/min
