Answer:
137
Step-by-step explanation:
The degrees of the inscribed arc of 43 is 43 * 2 = 86
Since the total degrees in a circle is 360, x is equal to
(360-86)/2 = 137
The perimeter, as you already know, is the sum of all the sides.
14)
15)
a rectangle has twin widths and twin lengths, therefore
Answer:
Approximately 120.31 people per square mile
Step-by-step explanation:
1) The population density can be found by dividing the whole population over the area.
2) Since the NH map is modeled like this triangle, let's firstly calculate its area.
3) Based upon the original picture, and tracing it on we can easily see that the y coordinate is little bit over 200, precisely 220. Each mark on the original y-axis count as 20 miles. That'll give us the height.
The base of the triangle is 100 miles for F(100,0). Plugging that information on the formula:
4) The Population density:
Answer:
These are both 20 so that means that this is proportional, yes.
Step-by-step explanation:
Hi.
To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.
Here is how we do this.
So basically what we are doing is multiplying across in a diagonal direction.
Diagonal meaning like a slash / .
So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.
Do the same for the 2 and the 10.
So we have to multiply :
4 x 5
2 x 10
=
20
These are both 20 so that means that this is proportional, yes.
Hope this helps.
