Which of the statements about the diagram is INCORRECT?
A) ∠ 1 ≅ ∠2
B) BE ≅ ED
C) BE ≅ CE
D) CE ≅ EA

Answer:

To find the area of an irregular polygon you must first separate the shape into regular polygons, or plane shapes. You then use the regular polygon area formulas to find the area of each of those polygons. The last step is to add all those areas together to get the total area of the irregular polygon

Answer:

3 <x

Step-by-step explanation:

3(8 - 4x) < 6(x - 5 )​

Divide each side by 3

3/3(8 - 4x) < 6/3(x - 5 )​

8 -4x < 2(x-5)

Distribute

8 -4x < 2x-10

Add 4x to each side

8 -4x+4x < 2x+4x-10

8 < 6x-10

Add 10

8+10< 6x-10+10

18<6x

Divide by 6

18/6 < 6x/6

3 <x

Start by distributing on both sides of this inequality.

This gives you 24 - 12x < 6x - 30.

Put your x's together on the left by subtracting 6x from both sides.

This gives you 24 - 18x < -30.

Now subtract 24 from both sides to get -18x < -54.

Now divide both sides by -18 and x > 3.

Remember to switch the direction of the inequality sign

when you divide both sides by a negative number.

I have also graphed it below on the number line.

Answer:

-1 not in domain

0 in the domain

2 in the domain

Step-by-step explanation:

g(x) = sqrt(8x)

g(-1) = sqrt(-8)   the answer is not real so not in the domain of real number

g(0) = sqrt(0) = 0  in the domain

g(2) = sqrt(8*2) = 16 = 4  in the domain

Answer:

it would take 40

Step-by-step explanation:

12 inches = 1 foot

1 foot by 1 foot square tiles

And 40 square feet so

1 x 40 = 40

Answer: 50

Step-by-step explanation:

If 5 = x

You would substitute 5 in for X and start by squaring 5

Once you square 5 you get 25

Multiply 25 by 2 to get 50 and there is ur answer.

Apply the area formula [tex]A=\frac{bh}{2}[/tex] to get [tex]\frac{8\cdot 14}{2}=\boxed{56\,\text{square units}}.[/tex]

Answer:

Let the number be x

5 is subtracted from a certain number means it will be x - 5

The result is multiplied by 7, the final result is 63,

7 (x - 5) = 63

7x - 35 = 63

7x = 63 + 35

7x = 98

x = 98/7

x = 14

The number is 14

Answer the number is 14 and the equation is 7 (x - 5) = 63

Step-by-step explanation:

Using the appropriate arithmetic operation, the value of the original number is 4

Let the number be : p

5 added to p :

Multiply the addition by 7 :

We can solve for p thus :

15 + 3p = 27

3p = 27 - 15

3p = 12

p = 12/3

p = 4

Therefore, the original number is 4.

Answer:

18°

Step-by-step explanation:

First, we find the angle of the large piece of paper that is 1/4 of a circle.

The angle in a circle is 360°. The angle in 1/4 of a circle is:

1/4 * 360 = 90°

He cuts the paper into five equal parts from the center point of the circle. That means the angle was divided into 5 parts:

1/5 * 90 = 18°

Each part has an angle of 18°,

Answer: it's 18

Step-by-step explanation: 18 is the answer hope this helps

Answer:

y=1.5x + 68

Step-by-step explanation:

68 is the starting value and it increases by 1.5 every hour.

Answer:

y = 68 ( 1.5) ^x

Step-by-step explanation:

This is exponential growth

The formula is

y = ab^x  where a is the initial amount and b is the growth rate

The initial amount is 68 and the growth rate is 1.5

y = 68 ( 1.5) ^x

Answer:

FV=$823.004

Total interest earned=$63.004

Step-by-step explanation:

FV=PV×(1+i/n)^nt

PV=$760

I=4%

t=2 years

n=4

FV=760+(1+0.04/4)^4*2

=760+(1+0.01)^8

=760+(1.01)^8

=760+(1.0829)

=823.004

FV=$823.004

Total interest amount earned

=FV-PV

=$823.004-760

=$63.004

Answer:

lower price = 3

higher price =11

Step-by-step explanation:

p(x) = -2(x-3) (x-11)

Setting equal to zero

0 =  -2(x-3) (x-11)

Using the zero product property

x-3 = 0   x-11 =0

x=3          x = 11

Answer:

P(making 3 wrong guesses) = 27/64

P(making 3 right guesses) = 1/64

Step-by-step explanation:

Number of possible answers per question = 4

Number of right answer per question = 1

Number of wrong answers per question = (4 - 1) = 3

Probability = (Number of required outcomes / Number of Total possible outcomes)

A.) probability of guess 3 questions wrong :

Probability of making a wrong guess = (number of wrong options / total number of options

P(making a wrong guess) = 3/4

Therefore,

P(making 3 wrong guesses) = 3/4 × 3/4 × 3/4 = (27/64)

B.) probability of making 3 right guesses:

P(making a right guess) = (number of right options per question / total number of options per question)

P(making a right guess) = 1/4

P(making 3 right guesses) =(1/4 × 1/4 × 1/4) = 1/64

A linear function has one independent variable and one based variable. The independent variable is x and the based variable is y. a is the steady time period or the y-intercept. it's far the cost of the dependent variable while x = zero.

Which will be a linear feature, a graph needs to be both linear (a direct line) and a characteristic (matching each x-value to the most effective y-value). It must also pass a polygraph check, complete an obstacle path, and offer a minimum of 3 references. The qualifications are stringent.
