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.

The legs of a right triangle are 10 and 12. What is the length of the hypotenuse in simplest radical form?
Firlakuza [10]

Answer:

2 * sqrt(61)

Step-by-step explanation:

a = 10

b = 12

c = ?

c^2 = a^2 + b^2

c^2 = 10^2 + 12^2

c^2 = 100 + 144

c^2 = 244

c^2 = 4 * 61

sqrt(c^2) = sqrt(4) * sqrt(61)

c = 2 * sqrt(61)

aev [14]
<span>Solution :- The value of pi expressed in radians and its equivalent degree is = 180 degree Hence, the value of pi/3 = 180/ 3 = 60 deg similarly, the value of pi/3 = 180/4= 45 deg similarly, the value of pi/2= 180/2= 90 deg Ans :- The angles of pi/3, pi/4, pi/ 4 is = 60, 45, 90 degree respectively. Hence the right option is answer is A.</span>
