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:
27 I think just divide 81 by 3
B
Its because when you rearrange using this formula y=mx+c, where m is slope, if m is negative then that line has a negative slope
The given series is
Where the first term, a , is 3.
And the difference is constant, that is
So the constant difference, d is 3.
Since the difference is constant, so the given series is arthmetic.
And for explicit rule, we use the formula of nth term, which is
Substituting the values of a and d, we will get
Recursive rule is used to tell us the relationship between previous and current term. And the required rule is
Answer:
He needs to recompute.
Step-by-step explanation:
The product of three numbers all greater than 1 will not be less than 1. It will be greater than any of them.
1.5³ = 3.375 = 3 3/8 . . . . cubic cm
