Answer:

C. 9

Step-by-step explanation:

area \: of \: square =  {side}^{2} \\  \therefore \:   {side}^{2}  = 81 \\\therefore \:  side =  \sqrt{81}  \\ \therefore \:  side = 9 \: feet

Hence, side length of square = 9 feet.

Answer:

9 ft

Step-by-step explanation:

Area = 81 ft²

Area of square = length x length

A square has all its sides equal

Therefore

Area = L²

L² = 81 ft²

Find square root of both sides

sq rt L² = sq rt  81 ft²

L = 9 ft

Therefore length of the square = 9 ft

I hope this was helpful, please rate as brainliest

An amusement park charges a $15 entrance free plus $3.25 for each ride. Part A: Write an equation that represents the situation.
IceJOKER [234]

Answer:

Look below

Step-by-step explanation:

Part A: Equation would be in the y=mx+b format. m, or the slope, would be the cost that varies depending on the number of things that happen so m=3.25. b would be the fix cost so it is 15 so the equation ends up being y=$3.25x + $15.

Part B: Initial value is 15 since it is the fix cost, and 3.25 is the rate of change since it added as the number of rides increase.

Part 3: To solve this you substitute 7 into x so y=$3.25(7) + $15 = $37.75

I hope this explains it well.

Quadrilateral PUMA has coordinates at P(-5,-2), U(-1,2), M(4,-3), A(0,-7) and it is transformed by (x+3,y-5). Determined the ima
IgorLugansk [536]

The image of M is (7 , -8)

Step-by-step explanation:

Let us revise some transformation

  • If the point (x , y) translated horizontally to the right by h units  then its image is (x + h , y)
  • If the point (x , y) translated horizontally to the left by h units  then its image is (x - h , y)
  • If the point (x , y) translated vertically up by k units  then its image is (x , y + k)
  • If the point (x , y) translated vertically down by k units  then its image is (x , y - k)

∵ The quadrilateral PUMA has coordinates at:

   P (-5 , -2) , U (-1 , 2) , M (4 , -3) , A (0 , -7)

∵ It is transformed by (x + 3 , y - 5)

- That means the quadrilateral translated 3 units right and 5 units

   down, then we add each x-coordinate by 3 and subtract 5 from

   each y-coordinate

∵ The coordinates of point M are (4 , -3)

∴ The image of point M = (4 + 3 , -3 - 5)

∴ The image of point M = (7 , -8)

The image of M is (7 , -8)
