Answer:

The reasoning here is that the price should be based on the volume.

for a cylinder it's pi * r² * height

for a cone it's 1/3 * pi * r² * height

you'll notice that the formulas are the same, except that the cone is just one third of the cylinders volume.

so a fair price should be 70ct, ignoring packaging of course.

Anit [1.1K]

Answer:

Step-by-step explanation:

hi! so the question is asking what h is when you input -18 for x, right?

inputing in this question means to substitute, meaning that in this equation, -18 will take the place of x!

let's see what the equation looks like now
$h = 17 + \frac{-18}{6}$
easy as that!

now let's do the math :)

because of PEMDAS, remember to do the fraction (dividing) first!
$h = 17 + (-3)$

we can change that to --> h = 17 - 3

h = 14

let me know if you're still confused!

The company Digit Tech designs a new

Marat540 [252]

Answer:

The amount of cardboard Digit Tech needs to

package all 1500 new Smart Phones = 891000 square cm

Step-by-step explanation:

Points to remember:-

Surface area of cuboid

Surface area = 2(lb + bh + lh)

Where, l - Length of cuboid

b - Breadth of cuboid and

h - Height of cuboid

It is given dimensions of cardboard box

12 cm long, 9 cm wide, and 9 cm high.

To find the surface area of box

Here l = 12 cm, b = 9 cm and h = 9 cm

Surface area = 2(lb + bh + lh) = 2[(9*12) + (9*9) + (12 * 9)]

= 2(108 + 81 + 108) = 2 * 297 = 594 square cm

To find the cardboard required for 1500 box

Total cardboard = 1500 * 594 = 891000 square cm
