Bikes'R'Us manufactures bikes, which sell for $250. It costs the $180 per bike, plus a startup fee of $3,500. After how many bik
lions [1.4K]

<u>Answer:</u>

The bikes sold at break even by the manufacturer is 50 units

<u>Explanation:</u>

We know that break even point is given by  the following formula,

$\frac{\text { Fixed costs }}{\text { (Price per unit - Variable costs) }}$

We are given startup fee = $3500 which is the fixed cost,

the bikes sell for $250 which is the price per unit and

cost per bike is equal to $180

So substituting these values in the formula we get

= \frac{3500}{(250-180)}

= \frac{3500}{(70)}  = 50

= 50 units which is the number of bikes sold at break even by the manufacturer.

if the hieght and radius of the cone is tripled then find the ratio of Volume of the new cone and of that of original
solniwko [45]
\bf \textit{volume of a cone}\\\\&#10;V=\cfrac{\pi r^2 h}{3}\quad &#10;\begin{cases}&#10;r=radius\\&#10;h=height\\&#10;-----\\&#10;r=\stackrel{3\times r}{3r}\\&#10;h=\stackrel{3\times h}{3h}&#10;\end{cases}\implies V=\cfrac{\pi (3r)^2(3h)}{3}&#10;\\\\\\&#10;V=\cfrac{\pi (3^2r^2)(3h)}{3}\implies V=\cfrac{\pi (9r^2)(3h)}{3}\implies V=27\left( \cfrac{\pi r^2 h}{3} \right)

notice the original, and the new one, with the tripled "r" and "h" is just, whatever the original was times 27, namely 27 times as large as the original.

help The screen in a theatre is 22 ft high and is positioned 10 ft above the floor, which is flat. The first row of seats is 7 f
Stella [2.4K]
 <span>(a.) 
Let's say α is the angle that subtends from the top of the screen to horizontal eye-level. 
Let β be the angle that subtends from the bottom of the screen to horizontal eye-level. 

tanα = (22 + 10 - 4) / x = 28/x 
α = arctan(28/x) 

tanβ = (10 - 4) / x = 6/x 
β = arctan(6/x) 

Ɵ = α - β 
Ɵ = arctan(28/x) - arctan(6/x) 

(b.) 
tanƟ = tan(α - β) = (tanα - tanβ) / (1 + tanα tanβ) 
tanƟ = (28/x - 6/x) / [1 + (28/x)(6/x)] 
tanƟ = (22/x) / [1 + (168/x²)] 
tanƟ = 22x / (x² + 168) 
Ɵ = arctan[22x / (x² + 168)]</span>
