Amelie is making a recipe that uses 1 3/4 cups flour. She is making 2 1/2 times the original recipe.
elixir [45]

Answer:

She would need 4\frac{3}{8} flour to make  2\frac{1}{2} times the recipe.

Step-by-step explanation:

To make 1 recipe Amelia uses = 1 \frac{3}{4}\ cups of flour.

So, to make 2\frac{1}{2} times the recipe she would need =1 \frac{3}{4}\times 2\frac{1}{2}.

We evaluate the above mixed numbers by converting them to fraction(by multiplying denominator with whole number and adding to numerator and write as fraction of same denominator.).

=\frac{7}{4}\times \frac{5}{2}

=\frac{35}{8}

Then converting back to mixed number (by dividing the numerator by denominator and writing the quotient as the whole number and the remainder as fraction with same denominator.

\frac{35}{8}=4\frac{3}{8}

So, she would need 4\frac{3}{8} flour to make  2\frac{1}{2} times the recipe.

40pts and a brainliest to the person who can help me with this stock problem. PLEASE show all steps in detail so I can learn how
ruslelena [56]

Answer:

Rate of Return is 14.8%

Step-by-step explanation:

We know that 20 shares of Stock are purchased for $30 per share.

This gives us a total value of: 20 × 30 = $600.

Now, the shares are sold for $710 with a commission sale of $6. This means the final money going to the seller is; 710 – 6 = $704.

Thus, the rate of return percentage is = (704 – 600)/704) × 100% = 14.7727%

To the nearest tenth gives us 14.8%
