fiasKO [112]

Answer: Rounded: 236 seconds

Not rounded: 236.07 seconds

Step-by-step explanation: We know that it takes the car 54.9 seconds to travel one mile, and we know that 1 times 4.3 is 4.3, so 4.3 times 54.9 equals 236.07 seconds.

Write an expression for the sequence of operations described below.
den301095 [7]

Answer:

We conclude that:

''add 3 and the sum of 9 and v'' is algebraically represented by the expression as:

  • 3 + 9 + v

Step-by-step explanation:

Given the statement

''add 3 and the sum of 9 and v''

Let us break down the statement

  • Let the number be:  v
  • The sum of 9 and v: 9+v

so

Adding 3 and the sum of 9 and v will be: 3 + 9 + v

Therefore, we conclude that:

''add 3 and the sum of 9 and v'' is algebraically represented by the expression as:

  • 3 + 9 + v

Alexa used her compass to evenly divide the circumference of the circle below.
jok3333 [9.3K]

Answer:

  • triangle
  • square
  • hexagon
  • dodecagon

Step-by-step explanation:

The 12 points marked can be divided into this many equal-size groups:

  3, 4, 6, 12

so the figures that can be constructed are ...

  • triangle . . . . connects every 4th mark
  • square . . . . . connects every 3rd mark
  • hexagon . . . .connects every other mark
  • dodecagon . . connects every mark

_____

12 is also divisible by 1 and 2, but the minimum number of vertices in a regular polygon is 3.

If two similar polygons have perimeters of 36 and 21 inches.
jek_recluse [69]

Answer:

91

Step-by-step explanation:

Two similar polygons, means a similarity would exist in both polygons

  • Perimeter of a rectangle = 2(l +w)
  • Perimeter of the larger rectangle = 36 (because it's the largest figure)
  • equation becomes  36 = 2(L + W)
  • since L = 14, it becomes = 36 = 2(14 +W)
  • 36 = 28 + 2W
  • 2W = 36 - 28 = 2w = 8
  • w = 4.

Now we assume that since the rectangles are similar, they would have similar dimensions, in this case Width. so with this, we find length  of smaller rectangle.

  • 21 = 2(L + 4) = 21 = 2L + 8
  • 2L = 21 - 8 = 2L = 13
  • L = 13/2 = 6.5.

lastly the product of the length of both polygons = 14 * 6.5 = 91.

Their Products length is 91
