Sin30=cos(2x) then x=

Paraphin [41]

Answer:

x = 30.

Step-by-step explanation:

Use the identity sin A = cos (90 - A).

So sin 30 = cos (90 - 30) = cos 60.

cos 2x = cos 60

so x = 30.

Your supervisor instructsyou to purchase 240 pensand 6 staplers for thenurse's station. Pens arepurchase in sets of 6 for$2.35 p

sveticcg [70]

Given:

Number of pen you are to purchase = 240 pens

Number of staplers you are to purchase = 6 staplers

Cost of pen in sets = 6 for $2.35

Cost of stapler in sets = 2 for $12.95

Let's find how much it will cost to purchase these products.

First find the average cost of each item:

$\begin{gathered} \text{Average cost of pen = }\frac{2.35}{6} \\ \\ \text{Average cost of stapler = }\frac{12.95}{2} \end{gathered}$

To find the total cost, we have the equation:

Total cost = (Average cost of pen x number of pens to be purchased) + (Avg cost of stapler x number of staplers to be purchased)

$\text{Total cost = (}\frac{2.35}{6}\times240)+(\frac{12.95}{2}\times6)$

Let's evaluate the equation:

$\begin{gathered} \text{Total cost = (}\frac{2.35\times240}{6})+(\frac{12.95\times6}{2}) \\ \\ \text{Total cost = (}\frac{564}{6})+(\frac{77.7}{2}) \\ \\ \end{gathered}$
