I know that the answer is y! I hope it’s right
The horizontal axis of the graph represents time, from 65,000 BCE (Before Current Era) to the present. Periods of 5,000 years are separated by vertical lines.
The vertical axis shows the total size of the world population, which has grown spectacularly over the period. Between 50,000 BCE and the present day, the number of human beings has risen from around 600,000 to 6.5 billion, a ten thousand-fold increase.
If that helps :)
Answer:
The maximum length is 170 feet and maximum width is 340 feet.
Step-by-step explanation:
Let the length of the parking = x feet and width = y feet.
Since, the fencing is to be applied on three sides of the lot.
So,we get,
i.e.
Since, the area of the rectangular lot = Length × Width
So, area of the lot =
i.e. area of the lot =
i.e. area of the lot =
Now, we know the maximum value of 'x' in is .
So, the maximum length of the lot is x= = = 170 feet.
Then, i,plies implies i.e. y= 340 feet.
So, the maximum length is 170 feet and maximum width is 340 feet.

Answer:</h3>
90°
<h3>
Step-by-step explanation:</h3>
The polygon has 7 sides, so the total of internal angles will be ...
... 180°×(7 -2) = 900°
The sum is then ...
... x + 146° +122° +142° +140° +110° +142° = 900°
... x + 802° = 900° . . . . . simplify
... x = 98° . . . . . . . . . . . . .subtract 802°

<em>Comment on angle measure formula</em>
The usual formula for computing the total of internal angles of a convex polygon with n sides is ...
... total angle measure = (n -2)×180°
This can be simplified from the fact that the sum of external angles is always 360°. That is, for internal angles a1, a2, ..., an, the sum of external angles is ...
... (180° -a1) +(180° -a2) +... +(180° -an) = 360°
... n×180° -(a1 +a2 +... +an) = 360° . . . . . . collect terms
... n×180° -360° = (a1 +a2 +... +an) . . . . . . add ∑ak -360°
... 180°×(n -2) = a1 +a2 +... +an . . . . . . . . . factor out 180°
