30 300 000 is 30.3 million expanded.
Answer:
52
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here the sum = 9000°, thus
180° (n - 2) = 9000° ( divide both sides by 180° )
n - 2 = 50 ( add 2 to both sides )
n = 52
Answer:
A = 84 inches^2
Step-by-step explanation:
We know that the formula for the area of a triangle is given by
A = 1/2 b*h
Let's substitute what we know
We need the units to be the same
Convert 7 ft to inches
1 ft = 12 inches
Multiply both sides by 7
7 ft = 84 inches
A = 1/2 *84*2
A = 84 inches^2
