100 is the nearest whole number because anything that is equal or more than 5 is changed.

7. A shirt marked at $600 is sold at 30% off.

ella [17]

Answer:

a) $420 b) $399

Step-by-step explanation:

a) $600 = 100%

$60 = 10%

$60 times 3 gives 30% = $180

$600 - $180 = $420

b) $420 = 100%

$42 = 10%

$21 = 5%

this means, they profitted by $21.

so $420 - $21 = $399

therefore, $399 is the cost price

Evaluate the function f(x) at the given numbers (correct to six decimal places). f(x) = x2 − 3x x2 − 9 , x = 3.1, 3.05, 3.01, 3.

Lostsunrise [7]

Answer:

Values of f(x) for different values of x.

Step-by-step explanation:

We are given the following function in the question:

$f(x) = \displaystyle\frac{x^2-3x}{x^2-9}$

We have to find the value of given function at the following x.

x = 3.1, 3.05, 3.01, 3.001, 3.0001, 2.9, 2.95, 2.99, 2.999, 2.9999

$f(x) = \displaystyle\frac{x^2-3x}{x^2-9}\\\\f(3.1) = \frac{(3.1)^2-3(3.1)}{(3.1)^2-9} = 0.508197\\\\f(3.05) = \frac{(3.05)^2-3(3.05)}{(3.05)^2-9} = 0.504132\\\\f(3.01) = \frac{(3.01)^2-3(3.01)}{(3.01)^2-9} = 0.500832\\\\f(3.001) = \frac{(3.001)^2-3(3.001)}{(3.001)^2-9} = 0.500083\\\\f(3.0001) = \frac{(3.0001)^2-3(3.0001)}{(3.0001)^2-9} = 0.500008\\\\f(2.9) = \frac{(2.9)^2-3(2.9)}{(2.9)^2-9} = 0.4915254\\\\f(2.95) = \frac{(2.95)^2-3(2.95)}{(2.95)^2-9} =0.495798\\\\$

$f(2.99) = \displaystyle\frac{(2.99)^2-3(2.99)}{(2.99)^2-9} =0.499165\\\\f(2.999) = \displaystyle\frac{(2.999)^2-3(2.999)}{(2.999)^2-9} = 0.499917\\\\f(2.9999) = \displaystyle\frac{(2.9999)^2-3(2.9999)}{(2.9999)^2-9} =0.499991$

Dylan and sonia arw hiking different trails. If dylan hiked riverwalk and mountainview , and sonia hiked mountainveiw and pine ,

jenyasd209 [6]

I assume that the values appearing after the equal signs for Riverwalk, Mountainview, and Pine are the distances in miles. For Dylan who hiked Riverwalk and Mountainview, the total distance covered is,
3/4 + 1/2 = 5/4 or 1.25 miles
For Sonia who hiked Mountainview and Pine, the distance covered is,
1/2 + 3/5 = 11/10 or 1.1 miles
