The 30 members of a choir are trying to raise at least $1,500 to cover travel costs to a singing camp. They have already raised
Darya [45]

Answer:

B

Step-by-step explanation:

30 is the amount of members and each have to raise at least the goal but they have already raised $600. For them to reach this goal the amount they get does not have to be more than the goal since it's at least and they need to raise the goal. So they need to raise at least $1500 which leads us to answer B 30x+600>=1500 (in word terms thirty x plus six hundred is greater than or equal to fifteen hundred). Hope this helps and I got threw this a little while back sucks at first but you'll get it with time easier.

Hlol can u plz solve b no plz plz.....I will mark as brainliest​
zimovet [89]

Answer:

Step-by-step explanation:

Tan \ B =\frac{4}{3} = \frac{opposite \ side \ of B}{adjacent \ side \ of B}

BC = 15 cm

3x = 15

x = 15/3 = 5

AB =4x = 4*5 = 20 cm

Pythagorean theorem,

AC² = AB² + BC²

       = 20²  + 15 ²

       = 400 + 225

       = 625

AC = √625 = 25 cm

AC = 25 cm

Sin \ A = \frac{opposite  \ side \ of \ angle A }{hypotenuse}\\\\  = \frac{BC}{AB}=\frac{15}{25}=\frac{3}{5}
