8. Find the area of the regular polygon.​
Sliva [168]

Answer:

To find the area of a regular hexagon, or any regular polygon, we use the formula that says Area = one-half the product of the apothem and perimeter. As shown below, this means that we must find the perimeter (distance all the way around the hexagon) and the measure of the apothem using right triangles and trigonometry. Area of a Hexagon

In the given diagram abc is a right angle with DG CB segment AB is divided into four equal parts . The coordinates of point F ar
pickupchik [31]

Answer:

E(3.75,-2.5)

G(-0.75,-3)

Step-by-step explanation:

Point E is the midpoint of the segment AB, then it has coordinates

\left(\dfrac{-3+6}{2},\dfrac{-1+(-3)}{2}\right)=\left(\dfrac{3}{2},-2\right).

Point F is the midpoint of the segment EB, then it has coordinates

\left(\dfrac{\frac{3}{2}+6}{2},\dfrac{-2+(-3)}{2}\right)=\left(\dfrac{15}{4},-\dfrac{5}{2}\right)=(3.75,-2.5).

Let S be the midpoint of segment CB, then it has coordinates

\left(\dfrac{-3+6}{2},\dfrac{-3+(-3)}{2}\right)=\left(\dfrac{3}{2},-3\right).

Point G is the midpoint of segment CS, then its coordinates are

\left(\dfrac{\frac{3}{2}+(-3)}{2},\dfrac{-3+(-3)}{2}\right)=\left(-\dfrac{3}{4},-3\right)=(-0.75,-3).

A linear function has the same y-intercept as x + 4y = 20 and its graph contains the
TEA [102]

Answer:

x + 4y = 20

Step-by-step explanation:

Step 1: Subtract "x" on both sides.

           x + 4y = 20

          <u>-x            -x</u>

Step 2: Simplify --> 4y = -x +20

Step 3: Divide 4 on all sides to leave "y" by itself.   4y = -(1)x + 20

                                                                                  4      4     4

Step 4: Simplify: y = -1/4x + 5

Answr: The Slope is "-1/4". The slope will always be the number in front of the "x".

A grocer reports that the store has sold 72 of the 90 boxes of apples delivered this week. What percentage of the delivered appl
rosijanka [135]

Answer:

80%

Step-by-step explanation:

Total boxes of apples delivered = 90

Total boxes sold = 72

What percentage of the delivered apples have been sold?

Percentage sold = Total boxes sold / total boxes delivered × 100

= 72 / 90 × 100

= 0.8 × 100

= 80%

The percentage of the delivered apples have been sold is 80%

Percentage unsold = (total boxes delivered - total boxes sold) / total boxes delivered × 100

= (90 - 72) / 90 × 100

= 18 / 90 × 100

= 0.2 × 100

= 20%
