What is the area of the regular pentagon below
nordsb [41]

Answer:

A

Step-by-step explanation:

By definition, all sides of a regular polygon are equal in length. If you know the length of one of the sides, the area is given by the formula:

A=\dfrac{s^2\cdot n}{4\tan \frac{180^{\circ}}{n}},

where s is the side length, n is the number of sides.

In your case, s=20 ft, n=5,so

A=\dfrac{20^2\cdot 5}{4\tan \frac{180^{\circ}}{5}}=\dfrac{400\cdot 5}{4\tan 36^{\circ}}=\dfrac{500}{0.73}\approx 688.2\ ft^2

Malcolm ran the 440-yard and the 220-yard dash at a track meet.There are 3 in one yard. How many total feet did Malcolm run?Esti
Tresset [83]

For this case we have the following conversions:

1 yard = 3 feet

The estimate distance Is:

400yd = 1200feet

200yd=600 feet

Ten, the estimate Is:

1200 + 600 = 1800 feet

The real distance Is:

The total distance in yards is given by:

440 + 220 = 660 yd

Then, let's transform this distance to feet, with the given conversion:

660 * 3 = 1980 feet

The distance traveled is reasonable for a person

Comparing the estimate and the actual answer, the distance malcom Ran Is reasonable.

Answer:

Malcolm ran 1980 feet.

The distance is reasonable.

Scorpion4ik [409]

Answer:

Step-by-step explanation:

Let's solve for x.

−3x+2y=−10

Step 1: Add -2y to both sides.

−3x+2y+−2y=−10+−2y

−3x=−2y−10

Step 2: Divide both sides by -3.

−3x /−3 = −2y−10 −3

x= 2 /3 y+ 10 /3

Answer:

x= 2 /3 y+ 10 /3
