A chemist is using 351 millimeters of a solution of acid and water. If 18.2% of the solution is acid, how many milliliters of ac

Zolol [24]

Answer:

The % of of acid in solution = 63.88 ml

Step-by-step explanation:

The solution of acid and water = 351 milliliters

The % of of acid in solution = 18.2% of 351 ml

Or, The % of of acid in solution = $\frac{18.2}{100}$ × 351 ml

Or, The % of of acid in solution = 63.882 ml

Hence ,The % of of acid in solution = 63.88 ml Answer

If the simple interest on $2000 for 3 years is $300, then what is the interest rate?

ivann1987 [24]

$~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\dotfill &\$300\\ P=\textit{original amount deposited}\dotfill & \$2000\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\dotfill &3 \end{cases} \\\\\\ 300=(2000)(r)(3)\implies 300=6000r\implies \cfrac{300}{6000}=r \\\\\\ \cfrac{1}{20}=r\implies 0.05=r\implies \stackrel{\textit{converting to percent}}{100\cdot 0.05}\implies \stackrel{\%}{5}=r$

Sam and Lou need a total of 1 foot of wire for a science project. Sam's wire measured 7/8- foot long. Do they have enough wire f

Reil [10]

Answer:

Yes, Sam and Lou have enough wire for science project.

Step-by-step explanation:

There is some data missing in the question, so complete question is below:

$Sam\ and\ Lou\ need\ a\ total\ of\ 1\ foot\ of\ wire\ for\ science\ project.$ $Sam's\ wire\ measured\ 8/12\ foot\ long.\ Lou's\ measured\ 7/8-\ foot \ \ long.$ $Do\ they\ have\ enough\ wire\ for\ the\ science\ project?$ $Explain \ your\ reasoning.$

Now, to get that whether they have enough wire for the science project or not.

Measurement of Sam's wire = $\frac{8}{12} \ foot.$

Measurement of Lou's wire = $\frac{7}{8}\ foot.$

Now, adding both the wires of Sam and Lou:

$\frac{8}{12} +\frac{7}{8} \\\\=\frac{16+21}{24} \\\\=\frac{37}{24}$

$=1\frac{13}{24} \ feet.$

As, Sam and Lou need a total of 1 foot of wire for the science project.

And, we see that the Sam's wire and Lou's wire combining gets $1\frac{13}{24}\ feet$ which is more than 1 foot.

Thus, wire they have is enough for science project.

Therefore, yes, Sam and Lou have enough wire for science project.

Answer:

they will need to win 18/20 matches

Step-by-step explanation:

if winning 9/10 matches gives them a winning percentage of 90% then you take 9/10 and multiple it by 2 since they played two times the matches of 10, then you get 18/20
