Answer:

Hey!

Your answer is 52.5

Step-by-step explanation:

50% x 35=

(50/100) x 35=

(50 x 35) / 100=

1750 / 100 = 17.50

NOW...

35+17.5=52.5

Step-by-step explanation:

f 35 = 100 % as a whole number then 50% = 17.5

50 % more than 35 must be 35 + 17.5 = 52.5

The length of a rectangle is 5m less than three times the width, and the area of the rectangle is 50m^(2). Find the dimensions o

Ilia_Sergeevich [38]

Answer:

The width is 5m and the length is 10m.

Step-by-step explanation:

Rectangle:

Has two dimensions: Width(w) and length(l).

It's area is:

$A = w*l$

The length of a rectangle is 5m less than three times the width

This means that $l = 3w - 5$

The area of the rectangle is 50m^(2)

This means that $A = 50$ . So

$A = w*l$

$50 = w*(3w - 5)$

$3w^{2} - 5w - 50 = 0$

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

$ax^{2} + bx + c, a\neq0$ .

This polynomial has roots $x_{1}, x_{2}$ such that $ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})$ , given by the following formulas:

$x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}$

$x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}$

$\bigtriangleup = b^{2} - 4ac$

In this question:

$3w^{2} - 5w - 50 = 0$

$a = 3, b = -5, c = -50$

$\bigtriangleup = (-5)^{2} - 4*3*(-50) = 625$

$w_{1} = \frac{-(-5) + \sqrt{625}}{2*3} = 5$

$w_{2} = \frac{-(-5) - \sqrt{625}}{2*3} = -3.33$

Dimension must be positive result, so

The width is 5m(in meters because the area is in square meters).

Length:

$l = 3w - 5 = 3*5 - 5 = 10$

The length is 10 meters

My photo is 8". If I want to reduce it by 12% five times. What is the size of my photo?

arlik [135]

To reduce a number by 12% we can simply multiply it by 0.88. If we repeat this 5 times we get 8, 7.04, 6.1952, 5.451776, 4.79756288, 4.2218553344.

We end up with 4.2218553344.

I think this is right.

The cost in dollars of making x items is given by the function C(x)=10x+600. (a) The fixed cost is determined when zero items ar

elena55 [62]

Answer:

- Fixed cost is 600

- The cost of making 15 items is 600

- The cost function is (100,1600)

Step-by-step explanation:

Given

$C(x) = 10x + 600$

Calculating (a) Fixed Cost

Fixed cost is when x = 0

Substitute 0 for x

$C(0) = 10 * 0 + 600$

$C(0) = 0 + 600$

$C(0) = 600$

<em>Hence, the fixed cost is 600</em>

Calculating (b) Cost of 15 items

Here, x = 15

Substitute 15 for x

$C(15) = 10 * 15 + 600$

$C(15) = 150 + 600$

$C(15) = 750$

Hence, the cost of making 15 items is 600

Calculating (c) Domain and Range

Here, C(x) = 1600

Substitute 1600 for C(x)

$1600 = 10x + 600$

Make x the subject of formula

$1600 - 600 = 10x$

$1000 = 10x$

$x = 100$

<em>Hence, the cost function is (100,1600)</em>
