Factor. 2v^2-11v-63

Tatiana [17]

Answer:

(2v +7)(v -9)

Step-by-step explanation:

Factors of 2·(-63) = -126 that have a sum of -11 are 7 and -18, so we can rewrite the middle term to -18v+7v. Then we can factor by grouping.

2v^2 -18v +7v -63 = 2v(v -9) +7(v -9)

= (2v +7)(v -9)

A mug is 1/8 full. The mug contains 1/6 of a cup of water. Find the capacity of the mug. Write the answer as a fration or mixed

Andre45 [30]

Answer:

The capacity of the mug = $1\frac{1}{3}$ cups

Step-by-step explanation:

Given - A mug is 1/8 full. The mug contains 1/6 of a cup of water.

To find - Find the capacity of the mug. Write the answer as a fraction or mixed number

Proof -

Let the capacity of water = x

Given that,

A mug is $\frac{1}{8}$ full of water

⇒Total cups of water in the mug = $\frac{1}{8} x$

Now,

Given that, The mug contains $\frac{1}{6}$ of a cup of water.

∴ we get

$\frac{1}{8} x$ = $\frac{1}{6}$

⇒x = $\frac{1}{6}$ × 8

= $\frac{8}{6}$

= $\frac{4}{3}$ = $1\frac{1}{3}$

⇒x = $1\frac{1}{3}$

∴ we get

The capacity of the mug = $1\frac{1}{3}$ cups
