If a cylindrical vase has a 63 cubic centimeter volume an a cone has the same height and radius as the cylinder what is the volu

VladimirAG [237]

Answer:

$21cm^{3}$

Step-by-step explanation:

According to the problem, calculation of given data are as follows,

Volume of cylindrical vase = $63cm^{3}$

As, Cone has same height and radius as cylinder, than we can calculate volume of cone by using following formula,

Volume of cone = $\frac{1}{3}$ × Volume of cylindrical vase

By putting the value, we get

Volume of cone = $\frac{1}{3}$ × 63

Volume of cone = $21cm^{3}$

Using proportions, it is found that the total volume of the glass is of 216 cm³.

<h3>What is the missing information?</h3>

The problem is incomplete, but researching it on a search engine, it is found that:

Initially, the glass is 1/3 full.

After adding 63 cm³ of orange of juice, the glass is 5/8 full.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

Considering the volume of the glass as x, and the information given in the problem, the following equation can be built:

$\frac{x}{3} + 63 = \frac{5x}{8}$

We solve for x to find the volume of the glass as follows:

$\frac{5x}{8} - \frac{x}{3} = 63$

$\frac{15x - 8x}{24} = 63$

Then, applying cross multiplication:

7x = 24 x 63

Simplifying by 7:

x = 24 x 9

x = 216 cm³.

The total volume of the glass is of 216 cm³.

Mariana solved a linear equation and found that it had an infinite number of solutions. Which could have been the final line of

Fofino [41]

Answer:

0=0

Step-by-step explanation:

Well, the linear equation can be expressed as y=ax+b in the solution of linear equations, there 3 main cases can be concluded as final lines. 1st case - the linear equation has no solution (for example, 0*x=5 has no solutions). 2nd case - the linear equation has one solution (for example 4*x=3 where the only one solution is x=0.75) and the 3rd case - the linear equation has infinite number of solutions (for example 0*x=0). So, in our case (3rd case) the last line can be concluded as 0=0.

A CD player is on sale for $90 at an electronics store. If the original price was $125, what was the percent of discount

krek1111 [17]

This is the working of how it is 28% discount

Find the amount of discount : $125 - $90 = $35
Divide by the original price : $35/125 = 0.28
Change in to percentage : 0.28 x 100 = 28%

Therefore the percentage discount is 28% off
