7 gallons of pure acid and 14 gallons of 10% acid
This is how you solve this problem:
.10d + .05n = 5.25
(plug in the number of dimes we have)
(21 x .1) + .05n = 5.25
(multiply number of dimes x value of the dime)
2.10 + .05n = 5.25
(subtract 2.10 from both sides)
.05n = 3.15
(divide both sides by .05 to get the number of nickels)
n = 63 nickels
Hope this helps!
Answer:
11/13
Step-by-step explanation:
4 out of the 26 marbles are blue, meaning that the rest of the 22 marbles are not blue. (26-4=22)
This means that out of the total 26, the chance of not picking a blue marble are 22/26=11/13
Answer:
d. -0.301
h. 1.38
Step-by-step explanation:
Loga0.5 = loga2^-1
= -1(loga2)
= -1 (0.301)
= -0.301
Loga24 = loga(2^3 x 3)
= loga2^3 + loga3
= 3 (loga2) + loga3
= 3 (0.301) + (0.477)
= 1.38
