What is the simplified form of the expression k^3(k7/5)^-5

1 answer:

saveliy_v [14]2 years ago

4 0

The expression can be simplified as:

k^3(k7/5)^-5
= k^(3+-5) * (7/5)^-5
(Collecting the powers of k at one side and the constants at other side)
= k^-2 * (5/7)^5
(Solving thr integer powers)
= k^-2 * (3125/16807)

Is each line parallel, perpendicular, or neither parallel nor perpendicular to the line −3x+5y=−15? Drag and drop each choice in

nexus9112 [7]

The first line is perpendicular, the second line is not perpendicular and not parallel , the third line is parallel to the above line and the forth line not parallel or perpendicular to the line.

<h3>How can the slope of the line be calculate?</h3>

The slope of the line is been given as −3x+5y=−15

Then $y= \frac{3}{5x} -3$ , hence the slope is $\frac{3}{5}$

Slope of the first line 5x + 3y = 15 after calculation is

the slope is $y= \frac{5}{-3x} +5\\\\\frac{5}{-3}$

this means that the line is perpendicular to the given line

Slope of the second line 3x + 5y = 15 after calculation is

$y= \frac{3}{-5x} +15\\\\\frac{3}{-5}$

This means that the line is not perpendicular and not parallel

Slope of the Third line -3x + 5y = 15 can be calculated as

$y= \frac{3}{5x} +15\\\\\frac{3}{5}$

This means that the line is parallel to the above line.

Slope of the first line 3x + 5y = 15 after calculation is

$y= \frac{-3}{5x} +3\\\\\frac{-3}{5}$

This means that the line is not parallel or perpendicular to the line

An empty box weighs 200 g. The box is filled with birthday party goody bags and it now weighs 6.2 kg. Each goody bag weighs 150

Sliva [168]

Answer:

The number of goody bags inside the box=40

Step-by-step explanation:

Given the box weighs 200g

given the weight each goody bag be 150g.

Let the number of goody bag be x

Also given that the weight of the bag Long with the goody bags is 6.2Kg.

We know that 1Kg =1000 g.

So total weight= $6.2*1000$ =6200g

Total weight=weight of the bag + the number of goody bags * the weight of each goody bag.

Now

6200=200+ $150*x$

$x=6000/150$ =40

Therefore there are 40 goody bags
