1) What part of 20 is 5?<br> 2) What part of 20 is 12?

Ksivusya [100]

Answer:

Step-by-step explanation:

You find the part by expressing the ratio as a fraction, then simplifying.

1. 5/20 = (1·5)/(4·5) = (1/4)·(5/5) = 1/4

5 is 1/4 of 20.

2. 12/20 = (3·4)/(5·4) = (3/5)·(4/4) = 3/5

12 is 3/5 of 20.

In the solution, 3b + 9c = 3(b + 3). What should be done to make it CORRECT?

stiks02 [169]

Answer:

The second term of the binomial factor should be 3c instead of 3.

Step-by-step explanation:

Distributive property:

a*b + a*c = a*(b +c)

3b + 9c = 3*b + 3* 3 *c = 3*(b + 3c)

What is the volume of a cone when the radius is 6 and the height is 13

lidiya [134]

Answer:

<h2>489.84 units³</h2>

Step-by-step explanation:

Given,

Radius ( r ) = 6

Height ( h ) = 13

Volume of cone = ?

Now, Let's find the volume of cone:

$= \pi \: {r}^{2} \frac{h}{3}$

plug the values

$= 3.14 \times {6}^{2} \times \frac{13}{3}$

Evaluate the power

$= 3.14 \times 36 \times \frac{13}{3}$

Calculate

$489.84$ units³

Hope this helps..

Best regards!!
