Answer:
The volume is 75
Step-by-step explanation:
because the volume is the width, length, and height, add them together.
Below are the choices:
A. 80 mL of the 3.5% solution and 120 mL of the 6% solution
<span>B. 120 mL of the 3.5% solution and 80 mL of the 6% solution </span>
<span>C. 140 mL of the 3.5% solution and 60 mL of the 6% solution </span>
<span>D. 120 mL of the 3.5% solution and 80 mL of the 6% solution
</span>
Let fraction of 3.5% in final solution be p.
<span>p * 3.5 + (1 - p) * 6 = 4.5 </span>
<span>3.5p + 6 - 6p = 4.5 </span>
<span>2.5p = 1.5 </span>
<span>p = 3/5 </span>
<span>3/5 * 200 = 120 </span>
<span>Therefore the answer is B. 120 ml of 3.5% and 80 ml of 6%.</span>
Answer: 30
Step-by-step explanation:
10 is the started fingers of the hands
2 is fingers, 4 are the hands, 7 the fingers of the hands
2 + (4 · 7) = 30
-3 is the legs per day, and 365 are the days per year
-3 · 365 = -1095
this is a bizarre question
A = -16; b= + 32.
x= -32/(2* -16).
x= -32/-32 = 0.
16(0)^2+32(0)+48.
16 + 48 = 64.
Answer: 64
