What is the area of the ice skating rink

Answer:

Step-by-step explanation:

1.)

3x=3

x=1

2+y=0

y=-2

solution: (1,-2)

2.)

6y = -36

y = -6

-4x+12 = -12

-4x=-24

x = 6

solution: (6,-6)

Answer:

Top: x=1, y= -2

Bottom: x= 6, y= -6

Step-by-step explanation:

Top:

Isolate x for y: 2(3+y) + y = 0  

Simplify: 6+3y=0

Isolate y for 6+3y=0: y = -2

For x= 3 + y: x = 1

Bottom:

Isolate x for : -4x - 2y= -12:     x= [tex]\frac{-6 + y}{2}[/tex]

Simplify: 6y+ 12 = -24

Isolate y for 6y+ 12 = -24: y = -6

For x= [tex]-\frac{-6 -6 }{2} = 6[/tex] : x = 6

Answer:

The representation of Brian's situation in slope intercept form is:

                              y= 15x +70

Step-by-step explanation:

Let x be the number of weeks Brian started his collection.

y be the number of cards Brian has at present.

                         y= 45+25+ 15 x

                   or, y= 15 x +70

which is in the form of,

                              y= mx +c                (slope intercept form)

where,

m= slope

x= x- intercept

c= constant.

Answer:

10

Step-by-step explanation:

Answer:

okay I'm not 100% sure but I have a good idea (it's okay if u remove me it's just an educated guess)

89%

Step-by-step explanation:

if there were 100 students that would mean 1 student represented 1% of the results. so if there were 50 students 1 student would represent 2% of the results. so if two students were removed then that would mean the result would improve by a total of 4% which would get you 89%

Answer:

We can see from the table that 1 km is exactly half way between 2 and 3 laps. So it will take 2.5 laps to run 1 km.

Since it takes Angel 2 minutes to run 1 lap, she will take

2.5 laps1 km⋅2 minutes1 lap=5 minutes1 km.

So it takes Angel 5 minutes to run 1 km.

Since it takes Jayden 5 minutes to runs 3 laps, she runs 1 lap in 53 minutes. Thus, it takes Jayden

2.5 laps1 km⋅5 minutes3 laps=52⋅53 minutes/km=256 minutes/km=416 minutes/km.

So it takes Jayden 416 minutes to run 1 km.

Step-by-step explanation:

i actually dont know what the answer-answer is but i think this will help alot.

Answer:

Step-by-step explanation:

Distance traveled in 2 minutes by Angel = 2/5 kilo meter

Distance traveled in 1 minute by Angel = [tex]\frac{2}{5}[/tex] ÷ 2

                                                                 [tex]=\frac{2}{5}*\frac{1}{2}[/tex]

                                                                 = 1/5 kilometer

Answer:

area =12

Step-by-step explanation: you don't need to use all 4 numbers just used the base which is 8 then times it with 3 which gives you 24 then divided it by 2 which gives you 12.

Answer:

Area=12

Step-by-step explanation:

You take the height which is 3 and multiply it by the base which is 8. Then you get 24 and divide it by 2 which gives you 12.

*The 5s don't matter*

Answer:

so in the first box next to -3 it would be -8

the next box would be 1

and the last one would be 7

then the other table the first box would be 1

then the second would be -2

and the last would be -6

and I hope you know how to graph

Answer:

b

Step-by-step explanation:

area= (radius)^2.pi:2

         = 3.3.3.14:2

        = 14.13 (in)^2

the area in red ishalf the area of the circle with a radius of three

Answer:

Step-by-step explanation:

area of square=8²=64  m²

radius of each circular arc at the corner=8/2=4 m

area of  four circular arcs=4×1/4 ×π×4²=16  π m²

area of shaded region=64-16π=16(4-π)≈13.73 m²

Step-by-step explanation:

Answer:

x = 15, Angles are both 130!

Step-by-step explanation:

Since this is an example of Alternate Exterior Angles, you could set these equal to eachother!

9x-5 = 7x + 25

-7x         -7x

Subtract 7x from both sides.

2x - 5 = 25

       +5   +5

Add 5 to both sides.

2x = 30

Divide by two to get x by itself .

x  = 15, now you can plug this in for X and get the angle

9(15) - 5 = 130

Answer:

Since this is an example of Alternate Exterior Angles, you could set these equal to each other! its 125

Step-by-step explanation:

9x-5 = 7x + 25

-7x -7x

Subtract 7x from both sides.

2x - 5 = 25

+5 +5

Add 5 to both sides.

2x = 30

Divide by two to get x by itself .

x = 15, now you can plug this in for X and get the angle

9(15) - 10 = 125

ur not gonna believe me....

Answer: A is yes. B is no, C is yes

Step-by-step explanation: The reason A is yes, is because the terms are 27b, 12b and 4 because they are separated. The reason B is no, is because the like terms are 27b and 12b because their variables are alike. The reason C is yes, is because 27b+12b=39b+4 is an équation simplified.

Step-by-step explanation:

to find a percentage of something you take the fraction and multiply it by a hundred

Step-by-step explanation:

step one

to determine what the fraction would be you just read the question:

first you have to see what they want to calculate the percentage of. In this case it's students who like traveling out of state but don't like camping.

88 students like traveling out of state and 36 of those students don't like camping so the fraction you have to use is 36/88

step two

next you multiply your fraction by 100 to calculate your percentage

36/88 ×100= 40.9%

step three

since you have to round to the nearest whole percent your answer would be 41%

Answer:

The Answer is 41%

Answer:

500 SQ Foot House Is The Answer.

Step-by-step explanation:

Answer:

A = 37 degrees ; B = 82 degrees

Step-by-step explanation:

the angle A plus 143 must measure 180 degrees

angle A = 180 - 143 = 37 degrees

the sum of the inner angles of a triangle is 180 degrees

A + B + C = 180

37 + B + 61 = 180

B = 180 - 98 = 82 degrees

Answer:

The total volume of water in the pool  = ( 6x^3 + 12x^2 - 90x ) ft^3

Step-by-step explanation:

The volume of water in the deep end = (2x^3 + 12x2 + 10x) ft^3

The volume of water in the shallow     =  (4x^3 -100x) ft^3

The total volume of water in the pool  = (2x^3 + 12x2 + 10x)  +  4x^3 -100x)

                                                              = ( 6x^3 + 12x^2 - 90x ) ft^3

Answer:

the answer is 28

Step-by-step explanation:

the mode is what comes up the most and 28 is the only one with 2

Answer:

Step-by-step explanation:

As points A and B have same x-coordinate, length of AB will be given by the difference of y-coordinate

AB = 13 - 2 = 11 units

As points C and D have same x-coordinate, length of CD will be given by the difference of y-coordinate

CD = 13 - 2 = 11 units

As points B and C have same y-coordinate, length of BC will be given by the difference of x-coordinate

BC = 15 - 12 = 3 units

As points A and D have same y-coordinate, length of AD will be given by the difference of x-coordinate

AD = 15- 12 = 3 units

AB = CD = 11 units

BC = AD = 3 units

So,ABCD is a rectangle

Area = 11 * 3 = 33 square units

Perimeter = 11+11+3+3 = 28 units

Answer:

At first

Length of AB = 13 - 2 = 11 cm

Length of CD = 13 - 2 = 11 cm

Length of BC = 15 - 12 = 3 cm

Length of AD = 15 - 12 = 3 cm

Now

Perimeter = 11 + 11 + 3 + 3

Perimeter = 22 + 6

Perimeter = 28

Area = 11 × 33 = 33 cm
