The pentagon ABCDE is graphed on a coordinate plane with vertices A(0, 0), B(3, 5), C(3, 8), D(8, 5), and E(8, 0). What is the pentagon's area?

Answers

Answer:

The answer is- 40

Step-by-step explanation:

( :

The area of the pentagon represented here is 40 units².

What is Area?

Area of a two dimensional shape is the total region which is bounded by the object's shape.

Given that the coordinates of the vertices of the pentagon given are A(0, 0), B(3, 5), C(3, 8), D(8, 5), and E(8, 0).

We have to find the area.

This pentagon can be divided in to triangle CBD and trapezium ABDE.

Find the area of each to find the total area of the pentagon.

Area of ΔCBD = [tex]\frac{1}{2}[/tex] × BD × CB

Using the distance formula,

BD = [tex]\sqrt{(8-3)^2+(5-5)^2}[/tex] = 5

CB = [tex]\sqrt{(3-3)^2+(5-8)^2}[/tex] = 3

Area of ΔCBD = [tex]\frac{1}{2}[/tex] × 5 × 3 = 7.5

Area of trapezium ABDE = [tex]\frac{1}{2}[/tex] × (AE + BD) × DE

Using the distance formula,

AE = 8, BD = 5 and DE = 5

Area of trapezium ABDE = [tex]\frac{1}{2}[/tex] × (8 + 5)5 = 32.5

Total area of the pentagon = 7.5 + 32.5 = 40 units²

Hence the total area is 40 units².

-2x-10=2x+14 i need all the steps

Answers

Answer:

x = -6

Step-by-step explanation:

1. always group the unknowns in this case, we 'bring' over the -2x to the right side so it becomes

-10 = 2x + 2x +14

2. Move 14 to the left side,

-10 - 14 = 2x + 2x

3. Carry out addition on both sides,

-24 = 4x

4. Simplify: since 24 is divisible by 4, so we divide 4 on both sides

-6 = x

Answer: x=-6.

Step-by-step explanation:

First, we need to choose an x side, and a non-x side. Let's choose the right side as the x side since it's coefficient of x is greater than that of the left side. So, we add 2x on each side to get rid of the x on the left side. Now, we have -10=4x+14. Next, we should subtract 14 from each side to get rid of the non-x terms on the right side. Now, we are left with -24=4x. Finally, we can divide by four on each side to get x=-6.

There are six important properties of parallelograms to know:

-Opposite sides are congruent (AB = DC).

-Opposite angels are congruent (D = B).

-Consecutive angles are supplementary (A + D = 180°).

-If one angle is right, then all angles are right.

Questions are in the Picture

Answers

Answer:

Step-by-step explanation:

For problem 10:

1. AE/ED=AC/CB (Since triangle ABC is similar to triangle ADE, we can determine that the ratio of AE to ED is equal to the ratio of AC to CB)

2. AE/ED=(AE+EC)/CB (Rewrite AC as the sum of the lengths forming it; This is sometimes referred to as the Partition Postulate)

3. 9/x=(9+6)/10 (Substitute the given values into this equation)

4. x=6 (Use algebra to solve for x)

For problem 11:

1. AG/AB=AE/AD (Use the same strategy as step one in problem 10, since the rectangles are similar we can create this equation)

2. AG/(AG+GB)=AE/(AE+ED) (Rewrite sides as the some of their parts)

3. 14/(14+7)=18/(18+x) (Substitute given values)

The diameter of a pizza is 14 inches. The pizza has 8 slices of equal size. Which of the following is the closest to the area of a slice?

Answers

Answer:

Step-by-step explanation:

First let us find the area of the whole pizza. Area of a circle is:

[tex]A=\pi r^2[/tex]

Then, we have diameter as:

[tex]diameter\div2=radius[/tex]

So, then using these formulas we would have,

[tex]16\div2=8\\A=8\pi \text{ or }25.12[/tex]

Now, one slice is [tex]\frac{1}{8}[/tex] of the entire pizza. So, we would have:

[tex]8\pi\div8=1\pi\\\text{ or }\\25.12\div8=3.14[/tex]

HOPE THIS HELPS!!!!!!!!
A full circle is 360 degrees, so one slice is an eighth of that. 360 / 8 = 45 degrees.

The locations of three fish relative to the water’s surface are –13 feet, –33 feet, and 22 feet. Which depth has the least absolute value?

A. -13 feet
B. -33 feet
C. 22 feet

Answers

Answer:

A. -13 feet

Step-by-step explanation:

absolute value has no negatives. it looks like this : |-13|

so once you take all the negatives away, you can easily spot the least one.

the reason why there is absolute value is for things like distance. You can't have negative distance because you just can't say "hey I walked -3 miles yesterday". Therefore, this question is also asking for which fish is closest to the water's surface.
