Vitek1552 [10]

Answer:

n = 20

Step-by-step explanation:

The number of diagonal that can be drawn in a polygon of n sides is given by :

D=\dfrac{n(n-3)}{2}

If the number of diagonals are 230, then put D = 230 in above formula. So,

230=\dfrac{n(n-3)}{2}\\\\460=n^2-3n\\\\n^2-3n-460=0

It is a quadratic equation, the value of n is equal to 20.

It means that for 230 diagonal, there are 20 sides of the polygon.

Elan Coil [88]

Answer:

(y-5t)/5=x

Step-by-step explanation:

y=5t+5x

factorize

y=5(t+x)

divide both sides by 5

y/5=5(t+x)/5

y/5=t+x

make x to stand alone

y/5-t=x

take lcm of 5 and 1

y/5-5t/5

a ruby throated hummingbird is about 4 in long and is it noted for its annual non-stop migration of 500 miles across the Gulf of
Goshia [24]

Answer:

7,920,000

Step-by-step explanation:

The question is asking the number of times that 4 inches fits in 500 miles. We need to divide 500 miles by 4 inches, but first we need to convert 500 miles into inches.

12 inches = 1 foot

5280 ft = 1 mile

500 miles * (5280 ft)/(1 mile) * (12 in.)/(1 ft) = 31,680,000 inches

Now that we know that 500 miles is the same as 31,680,000 inches, we divide that number of inches by 4 inches.

(31,680,000 inches)/(4 inches) = 7,920,000

Answer: 7,920,000
