Answer:

25.9

Step-by-step explanation:

So calculate volume of the mold, which is a cone: (pi) r2 (h/3) where r is radius and h is height

So diameter/2 = r which is 1.5 in

h = 2 in

V = (3.14)(1.52)(2/3) = 4.71 in3

If 1 in3 = 0.55 oz, and 1 mold = 4.71 in3, then one mold = 2.59 oz

2.59 oz * 10 cupcakes = 25.9 oz total

Step-by-step explanation:

the volume of a cone is

pi×r² × h/3

the radius is always half of the diameter, so, it is here

12/2 = 6 in.

h = 10 in.

so, we have here

pi×6²×10/3 = 3.14 × 36 × 10/3 = 3.14×120 = 376.8 in³.

2 cupcakes have then

376.8 × 2 = 753.6 in³

1 in³ = 0.55 ounces

so, the weight of 2 such cupcakes is

0.55 × 753.6 = 414.48 ounces ≈ 414.5 ounces

A ball is thrown upward from a height of 15 feet with an initial upward velocity of 5 feet per second. Use the formula b(t)= -16
ella [17]

Answer:

0.2 seconds

Step-by-step explanation:

The graph of b(t) = -16t^2 + 5t + 15 is a parabola opening downward.  The maximum value of b(t) occurs at the vertex.  The t-coordinate of the vertex is t = -5 / (2(-16)) = 5/32 = 0.15625 sec ≈ 0.2 sec.

What is the solution of 4 |x - 9| + 6 &gt; 42?
Galina-37 [17]

Answer:

0 <x> 18

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

 (4 • (x - 9) +  6) -  42  > 0  

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  4x - 72  =   4 • (x - 18)  

Equation at the end of step  3  :

 4 • (x - 18)  > 0  

Step  4  :

4.1    Divide both sides by  4  

Solve Basic Inequality :

4.2      Add  18  to both sides

            x > 18
