This is a discount, so you have to subtract the 25% by 100%

100% - 25% = 75%

Now multiply (change the percent to a decimal)

85 x 0.75 = $63.75

hope that helps :)

Answer:

1. x > 4

2. m < 2

3. x > 2

4. x < -6

Step-by-step explanation:

These 4 inequalities will be solved the same way we solve equations. We take variables to one side and numbers to another and use algebra to solve. Each of them are solved shown below:

$4+6x$

so x is greater than 4, we can write (variable first):

x > 4

$m+16>8m+2\\16-2>8m-m\\14>7m\\\frac{14}{7}>m\\2>m$

so m is less than 2, we can write:

m < 2

$5x-1>13-2x\\5x+2x>13+1\\7x>14\\x>\frac{14}{7}\\x>2$

so x is greater than 2, we can write:

x > 2

$-3x-2>-x+10\\-2-10>-x+3x\\-12>2x\\\frac{-12}{2}>x\\-6>x$

so x is less than -6, we can write:

x < -6

Find the area of a regular octagon with an apothem 9.7 meters long and a side length of 8 meters.

rosijanka [135]

The area of a regular octagon is:
A = a * P / 2, where a is an apothem and P is a perimeter.
P = 8 * 8 m = 64 m
A = 9.7 m * 64 m / 2
A = 620.8 / 2 m²
A = 310.4 m²
Answer:
The area of a regular octagon is 310.4 m².
