You are filling paper cones with popcorn for a party.
Sunny_sXe [5.5K]

Answer:

The amount of popcorn needed to  fill the paper cone is V=1,005\ cm^{3}

Step-by-step explanation:

we know that

The volume of a cone is equal to

V=\frac{1}{3}\pi r^{2} h

In this problem we have

r=8\ cm

h=15\ cm

\pi =3.14

substitute

V=\frac{1}{3}(3.14)(8)^{2}(15)

V=1,005\ cm^{3}

Carl ordered 2 pants at $22.54 and 2 shirts at $19.89 each. With a sales tax of 6% and shipping below, what was his total order?
Volgvan
The total cost of pants and shirts is given by:
 2 * (22.54) + 2 * (19.89) = 84.86 $
 In addition to this, we have 6% taxes, therefore, the total cost is:
 (1.06) * (84.86) = 89.9516 $
 Then, we must add to this value shipping charges.
 Since the value is between 75.01 and 125, then:
 Shipping charges = $ 8.95
 Adding we have:
 89.9516 + 8.95 = $ 98.9016
 Answer:
 
his total order was:
 
c) $ 98.90

Applied to the graph of y= 1/x
Bess [88]

Answer:

y = -3/(x-4) - 2

Step-by-step explanation:

3*y(x) vertically stretches <em>y</em> by a factor 3

-y(x) reflects <em>y</em> over x-axis

y(x-4) translates <em>y</em> 4 units to the right

y(x) - 2 translates <em>y</em> 2 units down

Applied the transformations we get:

y(x) = 1/x → 3/x → -3/x → -3/(x-4) → -3/(x-4) - 2
