Hi.
I'm going to tell you the process, since I don't have a calculator on me. Don't wanna risk it, lol.
We can break this shake into 2 parts: a rectangle, and a triangle.
To separate them, just calculate the area of the rectangle with 4 km & 3.5 km
Since the triangle's area is half that of the rectangle, all we need to do is divide the area of the rectangle by 2 to get the area of the triangle (it's confusing when in words, eh?)
Once you find the area of both, add them together.
This should get you the area of the shape.
I hope this helped. Once again, please let me know if there are mistakes.

if there is 39 music players and 13 headphones, 13 identical packages
Step-by-step explanation:
For question 7, if we add all votes for tiger and eagle, we get
tiger = 14 + 13 + 8 + 5 = 40
eagle = 6 + 7 + 12 + 15 = 40
so choices A and B are wrong.
C is also wrong because fifth and sixth grade votes for eagle are 6 + 7 = 13 and the 5th and 6th grade votes for tiger are 14 + 13 = 27. clearly 5th + 6th like tiger more.
D is the answer for question 7
question 8
rolling a cube does not affect the other cube so it is all independent probability.
cube: 1 2 3 4 5 6
3 even numbers and 3 odd numbers
so probability of rolling an even number is
1/6 + 1/6 + 1/6 = 3/6 = 1/2
multiplying by total number of rolls, she will get even numberss
300 * 1/2 = 150
about 150 time.
so half of the time, Cassie will roll and even number about half the number of rolls. never exactly since this is all probability. more likely for it to be around 150 times than exactly 150 time.
choice C is answer for question 8
Given:
A figure of a parallelogram.
The vertex angles are 
.
To find:
The values of a and b.
Solution:
We know that the pairs of consecutive angles of a parallelogram are supplementary angles. It mean their sum is 180 degrees.
(Supplementary angles)
Subtract 10 from both sides.
Divide both sides by 17.
Now,
And,
(Supplementary angles)
Divide both sides by 2.
Therefore, the value of a is 64 and the value of b is 10.
