A = fruit juice 40%

B= 90% juice

then

30 gallons + A = 55• C/100

30 gallons + N • (40/100) = (30 + N)• (55/100)

Now solve this equation, for N

3000 + 40N = (30+N) •55

then

3000 - 1650 = 55N - 40 N = 15N

1350 = 15 N

then

N= 1350/15 = 90

Then answer is

Should be mixed 90 gallons of 40% fruit punch

Use the distance formula to find distance between two points. Need help on this ASAP.
astra-53 [7]

Answer:

a) 20 units

b) 2 √10 units

c) 2 √17 units

Step-by-step explanation:

The distance formula is;

D = √(y2-y1)^2 + (x2-x1)^2

a) D = √(-7-9)^2 + (-7-5)^2

D = √256 + 144

D = √400

D = 20

b) D = √(10-8)^2 + (9-2)^2

D = √(2)^2 + 6^2

D = √4 + 36)

D = √40

D = 2 √10 units

c) D = √(1 + 7)^2 + (-8+10)^2

D = √(64 + 4)

D = √68

D = 2 √17 units
