A square dance floor has a perimeter of 120 yards. What is the length of a diagonal of the dance floor?
Crazy boy [7]

Answer:

Hey!

Your answer is C.42.4yd

Step-by-step explanation:

There are 2 ways you can work this on out...

1. Using Pythagoras Theorem...

= 30^2 + 30^2 = 1,800 (30^2=900 so you've added 2 of those to make 1,800)

= SQUARE ROOT THE ANSWER OF 1,800

\sqrt{x} 1,800= 42.42640687119285‬

TO GET A MORE PRECISE ANSWER WE ROUND IT UP TO 1 decimal place

= 42.4 yd is the diagonal length of the dance floor!!

HOPE THIS HELPS!!

Janice is 7 years older than Tam. Complete the table, and then graph this situation.
qwelly [4]

Answer:

The table in the exercise can be completed with the next results:

  • x          y
  • 2         <u>9</u>
  • 4         <u>11</u>
  • 6         <u>13</u>
  • 8         <u>15</u>

Step-by-step explanation:

As in the exercise Janice is 7 years older than Tam, to obtain the result in the table, you must add 7 to each age in the column x, with this we can make the next formula:

  • y = x + 7

Remember that x is Tam's age, and y is Janice's age, so, you must replace the x variable in each case to obtain the result to y:

When x is 2:

  • y = 2 + 7
  • <u>y = 9</u>

When x is 4:

  • y = 4 + 7
  • <u>y = 11</u>

When x is 6:

  • y = 6 + 7
  • <u>y = 13</u>

When x is 8:

  • y = 8 + 7
  • <u>y = 15</u>

At last, <u>to obtain the graph you can use the formula made: y = x + 7</u>, and you'll obtain a graph like the attached picture, <em>where each time x obtain a unit, the y variable obtain a unit too maintaining the diference of 7</em>.
