The purple pathers helipad is 1/3 of a mile from the control center we'll drop the food when it's 1/4 of the way there how many
AlexFokin [52]

Answer:

1/12 of a mile.

Step-by-step explanation:

1. Find a common denominator. In this instance, we can use the denominator of 12 because both 3 and 4 are multiples of 12.

2. Multiply each fraction (numerator and denominator) to convert them.

1/3(4/4) = 4/12

1/4(3/3) = 3/12

3. Subtract.

4/12-3/12 = 1/12

Papessa [141]
  • Midpoint Formula: (\frac{x_2+x_1}{2} ,\frac{y_2+y_1}{2} )

Plug the coordinates into the midpoint formula and solve as such:

(\frac{2+8}{2} ,\frac{-5+3}{2} )\\\\(\frac{10}{2} ,\frac{-2}{2} )\\\\(5,-1)

<u>Your midpoint is (5,-1).</u>

Factorise : x^2+x-72 Step by Step​
Ivan

Answer:

(x + 9)(x - 8)

Step-by-step explanation:

f(x) = x^2 + x - 72

     = x^2 - 8x + 9x - 72

     = (x^2 - 8x) + (9x - 72)

     = x(x - 8) + 9(x - 8)

     = (x + 9)(x - 8)

Two cones have the same radii but one has a height four times larger than the other. How many small cones would be needed in ord
hram777 [196]
Since the radius is the same but the height changes, the volume would change by the multiple of the height.
 In this case the volume of the larger cone would be 4 times as large as the smaller cone so you would need 4 small cones
