Change this radical to an algebraic expression with fractional exponents.

borishaifa [10]

Answer:

The exponent of y is 1

Step-by-step explanation:

Given

$\sqrt{y^2$

Required

Convert to fractional exponent

Here, we simply apply the following law of indices:

$\sqrt{x^m} = x^{\frac{m}{2}}$

So, the expression becomes:

$\sqrt{y^2} = y^{\frac{2}{2}}$

$\sqrt{y^2} = y^1$

$\sqrt{y^2} = y$

<em>From the above expression, the exponent of y is 1</em>

Sandra's printer can print 5 pages in 2/3 of a minute (40s). Show different ways to determine how many pages her printer can pri

Ne4ueva [31]

Answer:

$7\frac{1}{2}$ pages

Step-by-step explanation:

Method 1: Working with minutes

Let us assume that, Sandra's printer can print x pages in 1 minute.

Then we can write the equation:

$x:1=5:\frac{2}{3}$

We can rewrite the ratios as a fraction.

$\frac{x}{1}=\frac{5}{\frac{2}{3}}$

This simplifies to

$x=\frac{15}{2}$

$x=7\frac{1}{2}$

Method 2: Working with seconds

If 5 pages corresponds to 40 seconds, then we can write: $5:40$

Let y corresponds to 60 seconds (1 minutes).

Then:

$y:60=5:40$

We rewrite as fraction:

$\frac{y}{60}=\frac{5}{40}$

Multiply both sides by:

$y=\frac{5}{40}\times 60$

$y=\frac{300}{40}$

$y=\frac{15}{2}$

$y=7\frac{1}{2}$

Anyone know how to work this out

Leona [35]

Answer:

The perimeter is 70

Step-by-step explanation:

Isosceles means all sides same length. So to start out, you need to firgure out x so you can do let's say 3x-5=19x, or you can do 2x=19-x, or an combination pretty much. Once completing this, you find that x=14. Now all you have to do is plug 14 into all the x spots, and add everything together

Hope it helped :-)
