A tent was marked up 150% from an original cost of $52. Last Friday, Ethan bought the tent and paid an additional 10% in sales t
BARSIC [14]

$143

First you would have to find out the price that the tent was bumped up to.

52*150%=78

You then add the answer to your original price.

52+78=130

You then have to find the sales tax. You do this by multiplying 10% to your new price.

130*10%=13

You then have to add the sales tax to your number.

130+13=143

$143 is your answer.

Use linear approximation, i.e. the tangent line, to approximate √ 16.2 as follows: Let f ( x ) = √ x . Find the equation of the
Dvinal [7]

The linear approximation to f(x) near x=16 is

L(x)=f(16)+f'(16)(x-16)

We have

f(x)=\sqrt x\implies f(16)=4

f'(x)=\dfrac1{2\sqrt x}\implies f'(16)=\dfrac18

\implies L(x)=4+\dfrac18(x-16)=\dfrac x8+2

Then

f(16.2)\approx L(16.2)\iff\sqrt{16.2}\approx\dfrac{16.2}8+2

\implies\boxed{\sqrt{16.2}\approx4.025=\dfrac{161}{40}}

Answer:

  shaded/square = (50π cm²)/(400 cm²) = π/8

Step-by-step explanation:

The quarter circle has area ...

  A = (1/4)(πr²) = π/4(20 cm)² = 100π cm²

The half-circle has area ...

  A = (1/2)(πr²) = π/2(10 cm)² = 50π cm²

Then the area of the shaded portion is ...

  shaded = 100π cm² -50π cm² = 50π cm²

__

The area of the square is ...

  A = s² = (20 cm)² = 400 cm²

Then the ratio of interest is ...

  shaded/square = (50π cm²)/(400 cm²) = π/8
