<h3>Answer: 0.26%</h3>

Move the decimal point 2 spots to the right to convert from decimal form to percent form. This is the same as multiplying by 100.

Other examples:

0.17 = 17%

20 POINTS~<br><br> 2/5 |5x+10| -14 > -6<br> Please explain both answers

Pavlova-9 [17]

Answer:

$x2$

Step-by-step explanation:

We have the inequality:

$\frac{2}{5}|5x+10|-14>-6$

First, we can factor out a 5 from our absolute value. This yields:

$\frac{2}{5}(5|x+2|)-14>-6$

Simplify:

$2|x+2|-14>-6$

Add 14 to both sides:

$2|x+2|>8$

Divide both sides by 2:

$|x+2|>4$

Definition of Absolute Value:

$x+2>4\text{ or } -(x+2)>4$

Solve each case individually:

Case 1:

$x+2>4$

Subtract 2 from both sides:

$x>2$

Case 2:

$-(x+2)>4$

Divide both sides by -1. Flip the sign:

$x+2$

Subtract 2 from both sides:

$x$

So, our answers are:

$x2$

Since our inequality is a <em>greater than</em>, we will have an "or" inequality.

So, our answer is all values left to the first solution and all values to the right of the second solution:

$x2$

And we're done!

You can do 5+5+10, 6+6+8, 9+9+2, 4+4+12, 3+3+14, 2+2+16, 1+1+18. I believe these are all of them, so there are 7 ways.

The triangle below has an area of 75 units squared. Find the missing side.

Volgvan

Answer:

x = 15 units

Step-by-step explanation:

Here, base of triangle = x units & height = 19 units

$Area( \triangle) = \frac{1}{2} \times base \times height \\ \\ 75 = \frac{1}{2} \times x \times 10 \\ \\ 75 = x \times 5 \\ \\ x = \frac{75}{5} \\ \\ \huge \purple{ \boxed{ x = 15 \: units}}$
