What is the volume of a rectangular Prism if it is scaled down by a factor of 1/10? Original volume is 135.
Snezhnost [94]

Answer:

V=0.135\ units^3

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to teh scale factor elevated o the cube

Let

z ----> the scale factor

x ----> the volume of the dilated prism

y ----> the volume of the original prism

z^3=\frac{x}{y}

we have

z=\frac{1}{10}

y=135\ units^3

substitute

(\frac{1}{10})^3=\frac{x}{135}

solve for x

(\frac{1}{1,000})=\frac{x}{135}

x=135/1,000=0.135\ units^3

<h3>What is common Ratio ?</h3>

In a Geometric Sequence the ratio between each if the consecutive number is called the common Ratio.

Let Yui saving at the end of first month is Rs.x .

As given in the question

each month’s total is 5% greater than the previous month’s total.

Saving after second month is = First Month Total + 5% of First Month Total

= x + (5 % of x )

= x + (5*x/100)

= x + 0.05x

= 1.05x.

Yui balance is 1.05 times of Previous Month balance

Common Ratio = {Next Month }/ {Previous Month}

Common Ratio = 1.05 x / x

Common Ratio = 1.05
