Billy is reading a 595 page book. During the past five days, he has read 175 pages. If he continues to read at the same rate, ho

Morgarella [4.7K]

Answer:

12 more days

Step-by-step explanation:

If Billy read 175 pages in 5 days, that means he read 35 pages a day.

175 / 5 = 35 pgs

If we continue this same pattern it will look like this:

595 - 175 = 420

420 / 35 = 12 days

How can I simplify these?

Schach [20]

Answer:

$\large\boxed{343=7\sqrt7}\\\boxed{10\sqrt{96}=40\sqrt6}$

Step-by-step explanation:

$343=7^3=7^2\cdot7\\\\\sqrt{343}=\sqrt{7^2\cdot7}\qquad\text{use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\=\sqrt{7^2}\cdot\sqrt7\qquad\text{use}\ \sqrt{a^2}=a\ \text{for}\ a\geq0\\\\=7\sqrt7\\=====================\\\\96=16\cdot6\\\\10\sqrt{96}=10\sqrt{16\cdot6}=10\sqrt{16}\cdot\sqrt6=(10)(4)\sqrt6=40\sqrt6$

Select the correct answer.

bulgar [2K]

Answer:

Option A. is the correct option.

Step-by-step explanation:

We have to get the simplified form of sin (.6x)-sin(.4x)

As we know the identity sinA- sinB = 2 cos(A+B)/2.sin(A-B)/2

We apply the identity in the given expression

sin(.6x)-sin(.4x) = 2 cos(.6x + .4x)/2.sin(.6x - .4x)/2

= 2 cos(x/2).sin(0.2x/2) = 2 cos(0.5x).sin(0.1x)

Therefore option A is the correct option.
