Area of a right triangle is equal to (the length times the height) divided by 2

So the area of each tile is (3 x 3) / 2 = 4.5 square centimeters

200 tiles equal 200 x 4.5 = 900 sq cm

joja [24]

Answer: Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies.

Step-by-step explanation: <em>Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies. </em>

<em> </em>

<em>Then divide the total number of cookies by the number of guests:  84  21  = 4. Each person would get 4 cookies.</em>

<em> </em>

<em>This process can be modeled by the expressions 28(3) ÷ 21 and  </em>

<em>28(3) </em>

<em>21 </em>

<em>. This is because the fraction bar represents division.</em>

Area <br> help hellllppppp
slega [8]

Answer:

Area = 14¹/16 yd² or 14.0625 yd²

Step-by-step explanation:

2. The figure given is a square having equal sides of 3¾ yd each.

Formula for area of the square = a²

Where,

a = 3¾ yd

Plug in the value into the equation:

Area = (3¾)²

Change to improper fraction

Area = (15/4)²

Area = 225/16

Area = 14¹/16 yd² or 14.0625 yd²

If h is m above the ocean and your trying to find when the rocket reaches that ocean… as the function gives the height above the ocean at a given time, when the height equals 0 the rocket will have reached the ocean so solve for t when h=0. working out in the photo. i got t=48.88seconds
