A student can type 2/3 of a page in 1/5 hour. how many pages can the student type in an hour.

professor190 [17]

Here is your answer

$3 \frac{1}{3} pages$

REASON:

[CONCEPT USED: Unitary method]

Number of pages typed by student in 1/5 hour = 2/3

No. of pages typed by the student in 1 hour= $\frac{2/3}{1/5}$

= $\frac{2}{3}×5$

= 10/3

$3\frac{1}{3}$

So number of pages written in 1 hour are

3 pages and 1/3 of a page

Prove 2√(x) + 1/√(x + 1) <= 2√(x+1) for all x in [0,inf)

EleoNora [17]

Start by multiplying each side of the inequality by $\sqrt{x + 1}$ and simplifying:

$2 \sqrt x + \frac{1}{\sqrt{x+1}} \leq 2 \sqrt{x + 1}$
$(2 \sqrt x + \frac{1}{\sqrt{x+1}})(\sqrt{x + 1}) \leq (2 \sqrt{x + 1})(\sqrt{x + 1})$
$2 \sqrt{x(x + 1)} + 1 \leq 2(x + 1)$
$2 \sqrt{x^2 + x} + 1 \leq 2x + 2$
$2 \sqrt{x^2 + x} \leq 2x + 1$
$\sqrt{x^2 + x} \leq x + \frac{1}{2}$

From here, we can square both sides to get

$x^2 + x \leq (x + \frac{1}{2})^2$
$x^2 + x \leq x^2 + x + \frac{1}{4}$
$0 \leq \frac{1}{4}$ , which is always true.

Can we say that -3 belongs to the set of rational numbers? Give reason to support your answer.

Mariana [72]

Step-by-step explanation:

Yes.

Since the universal set of rational numbers range from negative infinity of rational numbers to positive infinity of national numbers, then -3 is part of the of rational numbers set.
