You have a bag containing 8 + 20 = 28 marbles.

After you pull a black marble you have 28 - 1 = 27 remaining marbles.

There are 20 yellow marbles in the bag.

The probability of pulling a yellow marble is now

$\frac{20}{27} which \: is \: approximately \: equal \: to \\ 74.07\%$

A multiple must be greater than or equal to the largest starting number. True or False

podryga [215]

I'll use multiples of 2 and 4 as an example:

Multiples of 2: 2, 4, 6, 8...

Multiples of 4: 4, 8, 12, 16...

The least common multiple in this case is 4. The LCM is always ≥ the largest starting number, which is 4 for this example. Therefore, the statement is true.

<em>Hope this helps! :)</em>

Express the area of this triangle as monomial.

gladu [14]

The formula of an area of a triangle:

$A=\dfrac{1}{2}bh$

b - base

h - height

We have b = 8x and h = 7x. Substitute:

$A=\dfrac{1}{2}(8x)(7x)=(4x)(7x)=28x^2$

<h3>Answer: 28x²</h3>
