A company has determined that the number of items it sells varies inversely as the price of the item. If 20,000 items can be sol

mestny [16]

Let N be the number of items sold and p the price.
Since the variation is inverse, then the relation between N and p is:
$N=k\dfrac{1}{p}$
For N=20000 and p = $9.5, we get the formula:
$20000=k\dfrac{1}{9.5}\\p=20000\times9.5=190000$
If p = 8.75, then the number of items sold can be computed using the formula:
$N= 190000\dfrac{1}{8.75}=21714 \text{ total items}$

Marrrta [24]

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.

(value/total value)×100%.

So,
9/45=0.2 x 100= 20%

Find the volume of the composite solid. Round your answer to the nearest tenth.

EastWind [94]

Answer:

646.04 cm³

Step-by-step explanation:

Cube volume formula:

V=l*w*h

V=8*8*8

V=512

Hemisphere volume formula:

V=(4/3πr³)1/2

V=(4/3π4³)1/2

V=128/3

Add both together

128/3 + 512 ≈ 646.04cm³

Evgesh-ka [11]

16x² - 8x + 1 = (4x)² - 2 · 4x · 1 + 1² =(4x - 1)²

Used: (a - b)² = a² -2ab + b²
