A Soccer Field Has A Width Of X And A Length Of X + 40. If The Perimeter Of The Field Is 240 Yards. Write

Answers

Answer 1

Answer:

x = 40

Step-by-step explanation:

We can solve this by taking the width and length that we're given, and put them into an equation for the perimeter of the soccer field.

The perimeter of a rectangle can be defined as 2l + 2w, so let's solve it using that:

[tex]p = 2l + 2w\\240 = 2(x + 40) + 2(x)\\240 = 2x + 80 + 2x\\240 - 80 = 4x\\4x = 160\\x = 40[/tex]

Answer 2
The answer to this question is 40

Step-by-step explanation:

Since the triangles are clearly indentical, the ratio of their lenghts is constant

12/18 = x/13.5

x = 2/3 * 13.5

x = 27/3

x = 9

Answer:

9

Step-by-step explanation

ΔABC and ΔDEF are similar

∴ [tex]\frac{AC}{DE}[/tex] = [tex]\frac{AB}{EF}[/tex]

∴ [tex]\frac{12}{18}[/tex] = [tex]\frac{AB}{13.5}[/tex] = [tex]\frac{2}{3}[/tex]

∴ AB = [tex]\frac{2}{3}[/tex] × 13.5 = 9

Write an equation for the sequence whose third item is 27 and each item is 5 more than the previous.

Answers

9514 1404 393

Answer:

  an = 17 +5(n -1)

Step-by-step explanation:

The first term can be found by working backward from the third term:

  third term = 27

  second term = 22 . . . . subtract 5 from 3rd term

  first term = 17 . . . . . . . . subtract 5 from 2nd term

The generic term is given by the formula ...

  an = a1 + d(n -1) . . . . . a1 = first term; d = common difference

Here, we have a first term of 17 and a common difference of 5. So, the sequence terms are described by ...

  an = 17 +5(n -1)

Answer:

 an = 17 +5(n -1)

How do you convert 5x + 12y = 13 into slope intercept form?

Answers

Step-by-step explanation:

12y = -5x + 13

y = -5/12 x + 13/12

The slope-intercept form is y = -5/12 x + 13/12.

Answer:

I Hope it help u  dear

Step-by-step explanation:

As given that ,

5x+12y=13

As we know the standard form of slope intercept form,

y=mx+ c

12y=13-5x      (subtracting 5x from both sides)

y=13/12-(5/12)x   (dividing 12 to both sides

y= -(5/12)x +13/12here m= -5/12  and c= 13/12

Answers

add plus 3 to y ( 1 , -3 )

Answer:

No they are not equivalent

Step-by-step explanation:

its pretty simple. so you do the y/x method, y over x as a fraction, -4/1, -7/2, -10/3, -13/4. So after you set them up you divide them.   -4/1= -4    -7/2= - 3.5               -10/3= -3.3    -13/4= -3.4 Then you see if the answers are equivalent ( if they have the same answer)  So no they are not equivalent. I hope this helps.

Answer: C, I think!

Step-by-step explanation: 3pi equals 9.4247. The square root of 100, is 10. So, that gives us 10/4. That simplified gives us 2.5.

For A, the square root of 36 is 6. 6 is in between 2.5 and pi, so that is not it.

For B, pi to the second power over 3 equals 3.2897, so that’s not it too!

For C, pi over 2 is 1.5708, so that is it, I’m pretty sure!
