Answer: 73 songs
Step-by-step explanation:
The online music club has a one- time registration fee of $13.95 and charges $0.49 to buy each song. Let x represent the number of songs that a member buys. This means that the amount that a member who just joins the music club pays for x songs would be
0.49x + 13.95
If Emma has $50.00 to join the club and buy songs, the maximum number of songs she can buy would be expressed as follows
0.49x + 13.95 = 50
0.49x = 50 - 13.95 = 36.05
x = 36.05/0.49 = 73.57
the maximum number of songs she can buy is 73 since the number of songs cannot be a fraction.
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
secx =
, cosecx = ![\frac{1}{sinx}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bsinx%7D)
cotx =
, tanx = ![\frac{sinx}{cosx}](https://tex.z-dn.net/?f=%5Cfrac%7Bsinx%7D%7Bcosx%7D)
Consider the left side
secA cosecA - cotA
=
×
- ![\frac{cosA}{sinA}](https://tex.z-dn.net/?f=%5Cfrac%7BcosA%7D%7BsinA%7D)
=
- ![\frac{cosA}{sinA}](https://tex.z-dn.net/?f=%5Cfrac%7BcosA%7D%7BsinA%7D)
= ![\frac{1-cos^2A}{cosAsinA}](https://tex.z-dn.net/?f=%5Cfrac%7B1-cos%5E2A%7D%7BcosAsinA%7D)
=
( cancel sinA on numerator/ denominator )
= ![\frac{sinA}{cosA}](https://tex.z-dn.net/?f=%5Cfrac%7BsinA%7D%7BcosA%7D)
= tanA = right side ⇒ proven
Good evening ,
Answer:
∠b = 12°
Step-by-step explanation:
∠a and ∠b are complementary angles ⇔ ∠a + ∠b = 90
Then ∠a =90 - ∠b = 90 - 78 = 12°

It is the indeed process of formation. You see you must first drop the em and so on.
Answer:
$9.84
Step-by-step explanation:
at 45% off the case is $5.41
Therefore this $5.41 is only 100% - 45% = 55% of the original price
x = original price
55% of x = $5.41
55/100 x = 5.41
x = 5.41 * 100 / 55
x = $9.84
