18. Find the length of the segment indicated. Round your answer to the
nearest tenth if necessary

Answer:

Step-by-step explanation:

1 = 1/16 (one chance on 16

2 = 7/16 (the non shaded parts are 7, while the total parts are 16)

3 = 11/16 ( 11 is unshaded + even)

4 = 4/16 = 1/4 (the favourable possibilities are: 13, 14, 15, 16)

Answer:

1.  (-6,-11)

2.(-2,5)

Step-by-step explanation:

y=2x+1

2x-3y =21

Take the first equation and substitute into the second

2x-3(2x+1) =21

Distribute

2x -6x-3 = 21

Combine like terms

-4x -3 = 21

Add 3 to each side

-4x-3+3 =21+3

-4x = 24

Divide by -4

-4x/4 = 24/-4

x = -6

Then find y

y = 2x+1 = 2(-6) +1 =-12+1 = -11

Elimination for problem 2

2x+3y=11 4x-3y=-23

Add the two equations together to eliminate y

2x+3y=11

4x-3y=-23

-----------------

6x = -12

Divide by 6

6x/6 = -12/6

x = -2

Multiply the first equation by -2

-4x+-6y=-22

4x-3y=-23

-----------------

 -9y = -45

Divide by -9

-9y/-9 = -45/-9

y = 5

Answer: 84 cm

Step-by-step explanation: The sides lengths are 25 cm and 17 cm. And to get parameter you have to add all the sides. So, it would be 25 + 25 + 17 + 17.

Answer:

Step-by-step explanation:

True

Option B is correct that is false.

We have been given a figure we need to tell that the two lines are perpendicular

Lines are perpendicular if they meet at the right angle.

Line CD is perpendicular AB to vice-versa is not true.

Hence, Option B is correct

Lines that intersect each other forming a right angle are called perpendicular lines. Example: the steps of a straight ladder; the opposite sides of a rectangle. The symbol is used to denote two perpendicular lines: ⊥ ⊥ .

The perpendicular symbol is ⊥. It is used between the two lines to show that they are perpendicular to each other. Perpendicular lines intersect at right angles (90°) while parallel lines are parallel to each other and never intersect.

Answer: Seating area

Step-by-step explanation: On the Graph there is the distance you just align 2 and 8 on the graph and it will point exactly on the seating area.

Answer:

Step-by-step explanation:

If the coordinates are (0, a) and (b, 0), we just use the distance formula to find the distance in terms of a and b:

[tex]d=\sqrt{(0-a)^2+(b-0)^2}[/tex] and

[tex]d=\sqrt{(-a)^2+b^2}[/tex] which simplifies to

[tex]d=\sqrt{a^2+b^2}[/tex]

and that's it!

Answer:

  (x -1)² +(y -4)² = 25

Step-by-step explanation:

The equation of a circle in standard form is ...

  (x -h)² +(y -k)² = r² . . . . . . . circle with center (h, k) and radius r

The graph shows your circle has its center at (1, 4) and its radius is 5. Then the equation is ...

  (x -1)² +(y -4)² = 25

Answer:

12 pet

Step-by-step explanation:

6 of Daniel pets are birds, that is chicken and Parrot.

But, Daniel has 2 parrots, therefore the number of chickens = 6 - 2 = 4. He has 4 chickens.

The number of chicken = number of goldfish - 1; number of goldfish = number of chicken + 1, hence number of goldfish = 4 + 1 = 5

Number of goldfish = number of turtles + 4; number of turtles = number of goldfish - 4 = 5 - 4 = 1.

Therefore total number of pets = Parrot + chicken + goldfish + turtles = 2 + 4 + 5 + 1 = 12

Daniel has 12 pets

Answer:

Since the Line is Perpendicular

m.m'=-1

The line

y=x+8

Comparing with

Y=mx + C

m=1

m.m'=-1

m'=-1/m = -1/1 = -1.

y-y' = m'(x-x')

The point it passes is (-7,8)

y-8= -1(x--7)

y-8=-1(x+7)

y-8 = -x - 7

y + x -1 = 0.

or In Slope intercept Form

Just Make y the subject

y= -x + 1 ..... This is your answer.

A 5040

B 35

Step-by-step explanation:

A  There are 7 ways to put the first picture.  There are 6 pictures left and 6 ways to put the 2nd picture.  There are now 5 pictures left and 5 ways to put the 3rd picture.  And so on

7 * 6*5*4*3*2*1

5040

B  If we can only have 3 pictures and order does not matter

7 choices for the first * 6 *5

But

We have to take into account order

The first picture can go into 3 slots, the second into 2 and the third 1 so divide by 6

(7*6*5)/ (3*2*1)

Answer:

The parallel sides are called the bases of the trapezoid

Step-by-step explanation:

[tex]area = (\frac{a + b}{2}) \times h[/tex]

       [tex]= \frac{14.1+22.7}{2} \times 18\\\\=331.2 \ unit^2[/tex]

Answer:

331.2 units^2

Step-by-step explanation:

There is a formula for the area of a trapezoid of legs a and b and width h:

a + b

----------- * h

     2

Here the leg lengths (which are parallel) are 14.1 and 22.7, and the width is 18.  Thus, the desired area is

14.1 + 22.7                        36.8

---------------- * 18  =  A  = ------------ * 18 = 331.2 units^2
