Find the volume of a sphere that has a surface area of 16 sq. in.

Vaselesa [24]

Given the surface area of the sphere, for us to obtain the volume we need to get the value of the radius. The surface area of the sphere is given by:
S.A=4πr^2
hence the radius can be calculated as follows;
16=4πr^2
4=πr^2
r=(4/π)^(1/2)
volume of a sphere is given by:
V=4/3πr^3
=4/3*π*(4/π)^(1/2))^3
=32/3 cubic inches

Let y = safe load in pounds and x = length in feet of a horizontal beam. A constant of proportionality k exists such that y=k/x

Contact [7]

Answer:

Option c. 30,000

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Let

y ----> safe load in pounds

x ----> length in feet of a horizontal beam

we have

For $x=15\ feet, y=2,000\ pounds$

Remember that

$k=y*x$

substitute

$k=2,000*15=30,000$

on selling a fan for rupees 4700 A shopkeeper loses 6% at what price must he sell it to gain 6 percentage

Sliva [168]

Given:

Selling price of a fan = Rs.4700

Loss percent = 6%

To find:

The price at which he must sell it to gain 6 percentage.

Solution:

Let x be the cost price of the fan.

Loss percent = 6%

Selling price = Cost price - 6% of cost price

$S.P.=x-\dfrac{6}{100}x$

$S.P.=x-0.06x$

$S.P.=0.94x$

Selling price of a fan = Rs.4700

$4700=0.94x$

$\dfrac{4700}{0.94}=x$

$5000=x$

So, the cost price of the fan is Rs.5000.

Now, he need to sell this fan in 6% gain.

Selling price = Cost price + 6% of cost price

$S.P.=5000+\dfrac{6}{100}\times 5000$

$S.P.=5000+300$

$S.P.=5300$

Therefore, he must sell it for Rs.5300 to gain 6 percentage.
