Answer:
120 mL
Step-by-step explanation:
If the 480 mL has 75% concentration, then 360 mL are alcohol. To turn the 360 into only 60%, you need to increase the amount of water.
Answer:
c is 110 degrees
b is 70 degrees
a is 20 degrees
Step-by-step explanation:
for c, 180-70=110
for b, 180- angle c=180-110=70
for a, 180-90-angle b=180-90-70=20
Since the number of members attending is 40, you can eliminate 17 as a possible answer, as it is smaller than 40. You can also eliminate 240 because 40 members is 60%, so the answer must be less than 80. You are now left with 67 and 73.
It is (a) because 40 divided by 67 = 0.597. 0.597 x 100 = 59.7% which is rounded to 60% of the club
Answer:
0.45
Step-by-step explanation:
Divide 9 by 20.
(22 + 15.50 + 2.75) 15
(22 * 15) + (15.50 * 15) + (2.75 * 15)
