The music store sold 12 trumoets and 19 clarinets last month. If clariners sell for $139.95 and the store made $4,578.45 from sa

Kamila [148]

Answer:

$159.95

Step-by-step explanation:

Let price of trumphet be defined by $x$

price of clarinet = $139.95

Number of clarinets sold = 19

Earning through clarinets' sale = $19*139.95 = 2659.05$

Total earning of store = $4578.45

Earning through trumphets' sale = $4578.45 - 2659.05 = 1919.40$

price of one trumohet = $\frac{1919.40}{12} = 159.95$

price of clarinet = $159.95

Given f(x) = 3 and g(x) = cos(x). What is lim [F(x) - g(x)]?

Flura [38]

Answer:

Step-by-step explanation:

$\lim_{n \to \ -\pi } (f(x) - g(x))\\\\ = \lim_{n \to \ -\pi } (3 - cos x)\\\\ = 3 - cos( - \pi) = 3 - cos(\pi)\\\\ = 3 - (-1) = 3 + 1 = 4$

What is the per capita cost of a $2.6 million recreation center in a city with 110945 people?

kvasek [131]

Answer: $23 per person

2,600,000/110,945 = 23.43035 (round to 5 decimal places)

The two significant digits of 23.43035 = 23

thus making it $23 per person.

Here is another example:

4,500,000/260,732= 17.25910

Two significant digits of 17.25910 = 17.25910 (without rounding). However, if it was 17.54210 it would be $18 per person. Hope those two examples help. If not let me know.
