A bicycle store costs $2400 per month to operate. Thee store pays an average of $60 per bike. The average selling price of each
n200080 [17]

Answer:

The number of bicycle that store sell each month to break even  is 13 bikes  .

Step-by-step explanation:

Given as :

The operation cost of bicycle store = $2400

The cost of payment by store at average rate = $60 per bike

The average selling price of each bike = s.p = $120 per bike

Let The number of bicycle that store sell each month to break even = n bikes

<u>According to question</u>

The operation cost of bicycle store = (cost of payment by store at average rate + average selling price of each bike ) × number of bicycle that store sell each month to break even

i.e ($60 per bike + $120 per bike) × n bikes = $2400

Or,  ($180 per bike) × n bikes = $2400

∴ 180 n = 2400

Or, n = \dfrac{2400}{180}

i.e n = 13.333 ≈  13

So, The number of bicycle that store sell each month to break even = n = 13 bikes

Hence, The number of bicycle that store sell each month to break even  is 13 bikes  . Answer

Im horrible at math and need help z and both w's

The sum of all the angles in a triangle is 180°.
There is a right angle -> a 90° angle on the hypotenuse of the largest triangle (the largest being the one that contains both smaller triangles)

To solve this problem, you don't really need to solve y.
Next to the 48° angle, you have two of the same angles, both x variables.
The sum of these three angles has to be 180°48 + 2x = 180 \\ 2x = 180 - 48 \\ 2x = 132 \\ x = 66

Now that we have x, we can calculate the value of z.
We add the value of x and the 90° angle, we later subtract it from 180°

Calculating the value of z:
66 + 90 = 156 \\ 180 - 156 = 24 \\ z = 24

If you really want to know the value of y, you just add up the 90° angle and the 48°, then subtract that from 180°
90 + 48 = 138 \\ 180 - 138 = 42 \\ y = 42
