A bottle of a​ cranberry-apple juice cocktail is 95 ​% juice. how many ounces of juice are in a 76 oz bottle of the juice​ cockt
FinnZ [79.3K]
95% = 95/100
95/100 of 76/1. (Always remember that every whole number is over 1)
So now we have 95/100 of 76/1
We can't solve with "of"
So we'll have to change it to "times(x)".....when we do that, it would cause 76/1 to reciprocate to 1/76
So now we have this: 95/100 x 1/76
When we solve it this is what we'll get: 19/20 x 1/76 = 19/1520 = 1/80

Solve a, b, c, & d please & I will mark you as Brainliest.
laila [671]

Answer:

Step-by-step explanation:

a) -2x-3y=5\\-5x+3y=-40\\-7x=-35\\x=5, y=-5\\\\b)5x+6y=-14\\x-2y=10\\Considering\ equation\ 2,\\3(x-2y)=3(10)\\3x-6y=30\\Hence,\\5x+6y=-14\\3x-6y=30\\8x=16\\x=2, y=-4\\\\c) -3x+3y=21\\-x-5y=-17\\Considering\ equation\ 2,\\3(-x-5y)=3(-17)\\-3x-15y=-51\\Hence, subtracting\ both\ the\ equations\ we\ get,\\-3x+3y=21\\3x+15y=51\\18y=72\\y=4, x=-3

d) Let the cost of one group lesson be x and one private lesson be y

12x+2y=110\\10x+3y=125\\By\ multiplying\ the\ first\ equation\ with\ -1.5\ in\ this\ system\ we\ get,\\-1.5(12x+2y)=-1.5(110)\\-18x-3y=-165\\Hence,\ by\ adding\ both\ the\ equations\ we\ get,\\-18x-3y=-165\\10x+3y=125\\-8x=-40\\x=5,y=25

Concert the angle 0=14r/9 radians to degrees
Mila [183]

Answer:

  θ = 280°

Step-by-step explanation:

We assume your intended equation is ...

  θ = 14π/9 . . . . radians

π radians is 180°, so we can simply put 180° where π is in your equation.

  θ = 14(180°)/9

  θ = 280°
