<u>331.5 inches²  </u><u>is the </u><u>area of the octagon</u><u>, rounded to the nearest square inch.</u>

What is octagonal in shape?

  • In geometry, an octagon is a polygon that has 8 sides and 8 angles.
  • All the sides are joined end to end to form the shape of the octagon.
  • The sum of the interior angles of an octagon is equal to 180 degrees.

Solving for an area of a regular octagon, we can make use of the formula shown below:

Area = 1/2 × apothem × perimeter

In this problem, the following values were given such as:

Apothem = 10 inches

Perimeter = 66.3 inches

Put the values in the formula

Area = 1/2 × 10 × 66.3

Area = 331.5 inches²

(07.07 lc) a cheetah runs at a speed of 49 miles for every hour. if the distance traveled, in miles, is d and time, in hours, is
alexgriva [62]

The relationship between d and t.

d = 49t

The correct equation is C.

<h3>What is Distance, speed and Time ?</h3>

How quickly something or someone is moving is determined by their speed. If you know how far an object has traveled and how long it has taken, you can calculate its average speed. Speed equals distance times time, according to the speed formula. Knowing the units for distance and time will help you determine what the units are for speed.

<h3>Given data:</h3>

speed = 49 miles/hour

Distance

Time

as we know :

Speed = Distance  /  Time .

Then:

49 = Distance/Time

Distance = 49*Time .

the relationship between d and t ( d = 49t).

Find the value of x in the figure
MA_775_DIABLO [31]

Answer:

x = 100

Step-by-step explanation:

57 \degree + (x + 23) \degree = 180 \degree..(straight \: line \:  \angle s) \\ (x + 80) \degree = 180 \degree \\ x + 80 = 180 \\ x = 180 - 80 \\  \huge \red{ \boxed{x = 100}}

Which of these is the algebraic expression for "eight less than some number?"
kipiarov [429]
B-8 would be the answer. This is because we are saying you have 8 less than something. So no matter what something is, we are taking away 8 from it. Since our something is unknown, we use our variable 'b' in its place, and subtract 8, giving us b-8.<span />
