Vickie made a recipe for 144 fluid ounces of scented candle wax. How many 1 cup candle molds can she fill with the recipe?
jeka57 [31]
There are 8 fluid ounces in 1 cup.  You can solve this problem using these proportions:

\frac{8}{1} = \frac{144}{x}

It states that there are 8 fluid ounces in every 1 cup and 144 fluid ounces in every <em>x </em>cups.  We have to solve for <em>x </em>using cross-multiplication:

8x = 144 \\ x=18

Vickie can fill 18 1 cup candle molds with 144 fluid ounces of scented candle wax.

Dorothy types 120 words per minute. How many words does Dorothy type in 1.75 minutes?
nirvana33 [79]
As you are looking for 1.75 minutes (or 105 seconds), the best thing to do is to find how many words she can type in 0.25 minutes (this is a quarter, and you can divide 1.75 by this). To find a quarter, you have to divide by 4, 120/4= 30. Therefore, every 15 seconds, Dorothy can type 30 words. As you've got 105 seconds, divide this by 15, and this gives you 7. Then multiply 30 by 7, and this gives you 210.
Dorothy can type 210 words in 1.75 minutes
Hope this helps :)

Emily reads a story book. o the first day, she reads 1/9 of the whole book, and on the second day, she reads 24 pages. The ratio
Marina86 [1]

There are 270 pages in this book.

Given that,

Emily reads a storybook the first day,

She reads 1/9 of the whole book, and on the second day, she reads 24 pages.

The ratio of the number of pages read to the remaining pages in the two days is 1:4.

We have to find

How many pages are there in this book?

According to the question,

Let, P is the number of pages,

The first day Emily reads p/9 pages of the whole book,

And the second day she read 24 pages.

The ratio of the number of pages read to the remaining pages in the two days = 1;4 = p/5.

Therefore,

The number of pages reads first day + the number of pages read the second day = The ratio of the number of pages read to the remaining pages in the two days

\rm \dfrac{p}{9} + 24 = \dfrac{p}{5}\\\\ \dfrac{p}{5} - \dfrac{p}{9} = 24\\\\\dfrac{p \times 9 - p\times 5}{45} = 24\\\\ \dfrac{9p-5p}{45} = 24\\\\\dfrac{4p}{45} = 24\\\\4p = 24\times 45\\\\4p = 1080\\\\p = \dfrac{1080}{4}\\\\p = 270 \ pages

Hence, there are 270 pages in this book.
