Answer:
-2.15
Step-by-step explanation: <em>I was kind of confused on what you asked. If you were asking for </em>0.4-2.55<em>, then that is the answer above.</em>
Step-by-step explanation:
x = ounces of 20% solution
15% = 0.15
20% = 0.2
17% = 0.17
x × 0.15 + 8×0.2 = (8 + x)×0.17
x×0.15 + 8×0.2 = 8×0.17 + x×0.17
8×0.2 = 8×0.17 + x×0.02
8×0.03 = x×0.02
x = 8×0.03/0.02 = 12 ounces
we need to mix the 8 ounces of 20% with 12 ounces of 15% to get 17% alcohol (8 + 12 = 20 ounces of it).
Answer:
a)2*2*2*2*2*2*2*2*2
Step-by-step explanation:
it wouldn't be done 2*9 but exactly how it is written like
2 by the power of 9
Perimeter= 2L + 2W
312 cm= 2L + 2(64)
312= 2L + 128
subtract 128 from both sides
184= 2L
divide both sides by 2
92 cm= L
ANSWER: The length is 92cm.
