In his stamp album, Jamal has 4 new stamps and 6 used stamps. Which ratio can be represented by three fifths ?

SashulF [63]

Answer:

The ratio of used stamps and total stamps can be represented by three fifths.

Step-by-step explanation:

It is give that Jamal has 4 new stamps and 6 used stamps.

New stamps = 4

Used stamps = 6

Total stamps = New stamps + Used stamps = 4 + 6 = 10

We need to find the ratio that can be represented by three fifths

$\dfrac{\text{New stamps}}{\text{Used stamps}}=\dfrac{4}{6}=\dfrac{2}{3}$

$\dfrac{\text{New stamps}}{\text{Total stamps}}=\dfrac{4}{10}=\dfrac{2}{5}$

$\dfrac{\text{Used stamps}}{\text{Total stamps}}=\dfrac{6}{10}=\dfrac{3}{5}$

Therefore, the ratio of used stamps and total stamps can be represented by three fifths.

The volume of a sphere is 256/3π cm3.

slava [35]

the surface area of the sphere is π/4 cm^3

<h3>How to determine the surface area</h3>

It is important to know the formula for surface area and volume of a sphere

Surface area = $\frac{4\pi }{r^2}$

Volume = $\frac{4}{3} \pi r^3$

First, let's determine the value of radius, r

The value for volume was given as 256/3π cm3.

$\frac{256}{3} \pi = \frac{4}{3} \pi r^3$

Pi cancels out and we have cross multiply to get the radius

$256 * 3 = 4 * 3 r^3$

$12r^3 = 768$

Make r the subject of the formula

$r = \sqrt[3]{\frac{768}{12} }$

$r = \sqrt[3]{64}$

r = 4

Let's substitute to find the surface area

Surface area = $\frac{4\pi }{4^2}$

Surface area = π/4

Surface area = π/4 cm^3

Thus, the surface area of the sphere is π/4 cm^3
