A frame is 9in wide and 6 in tall. If it reduces to a width of 3 in then how tall will it be?

Anarel [89]

Given

A frame is 9in wide and 6 in tall.

If it reduces to a width of 3 in

Find out the how tall will it be .

To proof

As given in the question

A frame is 9in wide and 6 in tall.

reduces to a width of 3 in

now as shown in the table given below

This table shows that the width of a frame is directly proportional to the height (tall) of the frame.

let us assume that the height of the frame after reduces width to 3in be = x

than the equation becomes

$\frac{original\ width}{original\ height} = \frac{reduces\ width }{reduces\ height}$

put the all the value

we get

$\frac{9}{6} = \frac{3}{x}$

solve the above

$x = \frac{6\times3}{9}$

x = 2in

therefore 2in tall will be the frame .

Hence proved

Answer:

6xand 4x

Step-by-step explanation:

but mainly when a number is on bracket u have to multiply it so 8 times 6x and 6 times 4x is the numbers with like terms

The formula for the volume of a sphere is v= 4/3 3.14rWhat is the formula solved for r?

prohojiy [21]

Answer:

$r = \frac{3}{4\pi}V$

Step-by-step explanation:

First, the formula for the volume of a sphere is:

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

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

$\frac{3}{4}V\frac{1}{\pi} = r^3$

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

$r = \sqrt[\leftroot{-2}\uproot{2}3]{\frac{3}{4\pi}V}$

Please help i don't even where to start solve for x

aliina [53]

The radius is 10, so the diameter is 20. This means the parts of the diameter (the chord through the center P) to the left and right of the vertical chord have lengths 16 and 4, respectively.

Because the horizontal chord is a diameter, the vertical chord is cut in half, so its parts above and below the diameter both have length x.

Now, by the intersecting chord theorem,

16×4 = x × x

x ² = 64

so that

x = 8
