Answers

Answer 1

Answer:

(a) 8

(b) 4

(c)5

Step-by-step explanation:

We are given multiple parts and we  need to provide the correct answer among the given options, also we need to prove that rest of the answers are wrong.

(a). X + 12 = 20 ( 12,8,20,0)

X= 20 -12

X= 8, so only 8 is the correct answer and rest are wrong.

Proof: lets take other given options into consideration

X= 12

X+12 =12+ 24 which is wrong because X+12 is already given as 20.

similarly,

X=20

X+12 = 20+12 = 36, which is wrong because X+12 is already given as 20.

X= 0

X+12 = 0+12 = 12, which is wrong because X+12 is already given as 20.  

(b). P - 4 = 0 (4,-4,8,0)

P-4 = 0

P= 4, So only 4 will give the correct answer and not the other options.

P= -4 = -4 -4 = -8, which is wrong because P-4 is is already given as 0.

similarly,

P = 8  = 8-4 = 4, which is wrong because P-4 is is already given as 0.

P = 0, 0-4 = -4 , which is wrong because P-4 is is already given as 0.  

(c). 2y - 3 = 7 (0,3,5,7)

       2y = 7 + 3

       2y = 10

          y = 5, only 5 will satisfy this given equation and rest will be wrong,

y = 0

2y-3 = 7

2(0) -  3 = 7

-3 = 7 which is not correct as LHS and RHS must be same.

similarly,

y = 3

2y-3=7

2(3) - 3 =7

6-3 = 7

3=7 which is again wrong.

y = 7

2(7) -3 =7

14-3 = 7

11=7, which is wrong.

Therefore the given options for the correct answers is verified and the wrong answers are given as the proof.

Julie takes her kids to a playground that has the shape shown. A. While her kids are playing, Julie wants to get some exercise. If she does 2 laps around the playground, how much distance has she covered? B. The park service is creating a flyer for the playground and wants to list the area that the playground covers. How much area does the playground cover?

Answers

Answer:

a.) Total distance Julie cover = 128 feet

b.) Total area , the playground cover = 256 ft²

Step-by-step explanation:

P. S : The exact question is -

As given,

Length of 1 side = 16 feet

As , we have

4 sides of same length

⇒ Total length of playground = 16 + 16 + 16 + 16 = 16(4) = 64 feet

a.)

As given Julie does 2 lap of the playground

⇒ Total distance Julie cover = 64 + 64 = 128 feet

b.)

As the playground has equal side, so it must be of square shape

And, we know

Area of square = (Length of one side)²

                        = ( 16 )² = 256 ft²

∴ we get

Total area , the playground cover = 256 ft²

Answers

First answer: -2

Second answer: 5

Answer:

(-2,5)

x= -2

y=5

Step-by-step explanation:

I'm going to solve this through substitution

We need a variable by itself (and we also need it to be positive)

We solve for y in the second equation

5x-y= -15

5x+15=y

We can then plug this in for y into the first equation

3x+2(5x+15)=4

and solve for x

3x+10x+30=4

13x= -26

x= -2

We can then plug this value in for x into any of the two beginning equations and solve for y

5(-2)-y= -15

-10-y= -15

-y= -5

y =5

Answers

Answer:

f= -40

Step-by-step explanation:

basically it means that f is being divided by 5. to have (f) alone you have to multiply 5 on both sides.

F is a variable, which for this equation means you have to find it. F could fit any number but in this specific equation, I means that f = -40. -40 or f, divided by 5 is equal to -8.

DIMENSIONS:

THE DOUBLE: 42.6 m cubed on both the length, width, and height

THE HALF: 10.6 m cubed on both the length width and height

THE CUBE: 21.3 m cubedon both the lengrh, width, and height

MOST HEIGHT: The Double at 42.6 m cubed

Step-by-step explanation:

We know that we have 64 m cubed. First, we should find out the volume of each cube. 64 times 2 is 128. This means the Double equals 128 in volume and half of 64 is 32. this means the Half is 32 in volume. Since these are all cubes, every side is exactly the same(or else it would be a rectangle) the formula for finding volume is length times width times height, we would divide EACH of the volumes by 3. 128 divided by 3 is 42.6 meaning the doubles dimensions would be 42.6 on each part of the cube (the lenght width and height would all be 42.6) you can check this by multiplying 42.6 by 3 which takes us back to 128. For the cube we would do 64 divided by 3 which is 21.3 pn every side and 32 divided by 3 is 10.6. The one with the most height is the double. I am not sure how to find the floor space I am super sorry but I hope this helps :)
