The royal fruit company produces two types of fruit drinks the first type is 70% pure fruit juice and the second type is 95% pur
Ipatiy [6.2K]
This is a typical mixture problem where using a table is the best thing.
                 pints juice        % juice     =      total % juice
juice A            x                  .70          =        .70x
juice B        60-x                 .95          =    .95(60-x)
total              60                  .75          =    60(.75)

The last row gives you a total that you need to use, so do that multiplication to get 45. You now to need to add the last columns together for rows 1 and 2 and set them equal to 45: .7x +.95(60-x) = 45. When you do that math, you'll get that x = 48. This means that you need 48 pints of juice A and 60-48 pints of juice B, which is 12 pints.

A number a decreased by 7 is 2.
umka21 [38]

Answer:

9

Step-by-step explanation:

Let's first convert this to numbers. When a number is decreased by a certain amount, that is the same as saying that something is subtracted from it. Therefore:

a-7=2

Add 7 to both sides:

a-7+7=2+7

a=9

Hope this helps!

PLEASE HELP ME I need an answer
son4ous [18]

Just for you beautiful!


Use distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

(11,-4) is (x1,y1) and (-12,-4) is (x2,y2)

Plug in and simplify

d = sqrt((-12 - 11)^2 + (-4 - -4)^2)

d = sqrt((-23)^2 + (0)^2)

d = sqrt(529 + 0)

d = sqrt(529)

d = 23 (positive because length cannot be negative) ;)
