Answer:

The sequence is a geometric sequence and the common ratio is 4.

Step-by-step explanation:

Because the difference between two pairs of adjacent numbers are not constant, the sequence has to be a geometric sequence. To find the ratio of a geometric sequence, just divide any of the two adjacent numbers. That would give you a ratio of 4 as your answer.

Answer:

2 game, $12

Step-by-step explanation:

Given data

Showplace Lanes charges

$4.50 per game as well as

$3 for shoe rental

Let the number of games be x

let the total charge for x games be y

y= 4.5x+3-----------1

Westgate Bowling charges

$4 per game and $4 for

shoe rental

Let the number of games be x

let the total charge for x games be y

y= 4x+4-----------2

Equate 1 and 2

4.5x+3= 4x+4

collect like terms

4.5x-4x= 4-3

0.5x= 1

divide both sides by 0.5

x= 1/0.5

x= 2 games

put x= 2 in equation 1 or 2

y= 4x+4-----------2

y= 4*2+4

y= 8+4

y= $12

The square root of a negative number is not defined in the set of real numbers.

Answer:

the answer is third one and last one hope it helps

Let

a------------> first number

b------------> second number

we know that

a+b=-7--------> a=-7-b----------> equation 1

a-b=14--------> equation 2

I substitute 1  in 2

(-7-b)-b=14-------------> -7-b-b=14----------> -7-2b=14-------> 2b=-7-14

2b=-21---------> b=-10.5

a=-7-b-------> a=-7-(-10.5)-----> a=-7+10.5------> a=3.5

the answer is

the two numbers are

a=3.5

and

b=-10.5

Answer:

7. 100

8. 56

9. 51

Step-by-step explanation:

Area of triangle: Length × breadth ÷ 2

Area of rectangle/square: Length × breadth

7. Area of shaded region = (20 × 10) - (20 × 10 ÷ 2)

                                          = 100

8. Area of shaded region = (8 × 8) - (4 × 4 ÷ 2)

                                          = 56

9. Area of shaded region = (15 × 5) - (3 × 8)

                                          = 51

Answer:

Step-by-step explanation:

Part A

Area of the deck = Area of rectangle A + Area of rectangle B

                            = (12 × 20) + (34 × 8)

                            = 240 + 272

                            = 512 square feet

Part B

∵ 200 square feet of the deck is covered by 1 can of stain

∴ 1 square feet of deck will be covered by the can of stain = [tex]\frac{1}{200}[/tex]

∴ 512 square feet will be covered by the stain = [tex]\frac{512}{200}[/tex]

                                                                             = 2.56

                                                                             ≈ 3

Therefore, 3 cans of stains will cover the entire deck.

Answer:

Step-by-step explanation:

-8x + 32 = -8 - 16

32 + 8 + 16 = 8x

4 + 1 + 2 = x

x = 7

Answer:

x=7

Step-by-step explanation:

-8x + 32 = -8 -16

First evaluate -8-16

-8x+32=-24<----

Subtract 32 on both sides

- 8x= - 56<----

divide by 8 on both sides

x=7

Answer:

area = 81.25 in²

Step-by-step explanation:

Answer:

For number 1, the answer is 90°, 55°, and 35°

Step-by-step explanation:

A triangle always equals 180 so you have to subtract the other angles to find the third one. Since you already know that one angle is 35° and the other is 90° you can do 180-90-35 and that equals 55 so those three are your three angle measures

For the show your work part of #1 write:

180°-90°-35°=55°

Answer: Reflection about the y-axis is according to the rule

(x,y)->(-x,y)

Therefore F(x,y) -> F'(-x,y)

The distance between F' and F is (-x,y)-(x,y)=-2x, or the positive distance is 2x.

Step-by-step explanation:

Answer:

none of the lines are parallel or perpendicular to each other

Step-by-step explanation:

which lines are parallel or perpendicular? line A:(-4,-1)(2,-2)line B:(-5,-3)(5,1) line C:(-2,-3)(2,-1)​

in order to know which lines are parallel or perpendicular, we need to find the slopes of the lines given

Slope M  = y2-y1/x2-x1

For line A;

Ma = -2+1/2+4

Ma = -1/6

Slope of line A is -1/6

For line B;

Mb = 1 -(-3)/5-(-5)

Mb = 1+3/5+5

Mb = 4/10

Mb = 2/5

The slope pf line B is 2/5

For line C;

Mc = -1-(-3)/2-(-2)

Mc = -1+3/2+2

Mc = 2/4

Mc = 1/2

Hence the slope of line C is 1/2

Since all the slopes are different , hence none of the lines are parallel or perpendicular

Answer:

84

Step-by-step explanation:

The length of LJ is 18 feet.

'An arc measure is an angle the arc makes at the center of a circle, whereas the arc length is the span along the arc. This angle measure can be in radians or degrees.'

According to the the given problem,

If we draw a dotted line from H to P and from J to P,

∠HKP = ∠JLP (Similarity of triangles)

HP = JP

KP = LP

⇒ ΔHKP ≅ ΔJLP

⇒ KH = LJ

Now, joining G and P,

GP = HP (radius of the circle)

PM is perpendicular to GH.

⇒ PM equally divides GH .

⇒ KH = GK = [tex]\frac{1}{2}[/tex] of GH

          = [tex]\frac{1}{2}[/tex] × 36

          = 18 feet

Hence, we can conclude that the length of LJ is 18 feet.
