14. A recipe calls for % cup brown sugar for

12345 [234]

Answer:

1 1/8 cup of brown sugar.

Step-by-step explanation:

Here is the correct question: A recipe calls for 3/4 cup brown sugar for each 2/3 cup white sugar. How many cups of brown sugar per cup of white sugar is this?

Given: 3/4 cup of brown sugar for each 2/3 cup of white sugar.

Finding requirement of brown sugar for 1 cup of white sugar.

∴ Each 2/3 cup of white sugar require 3/4 cup of brown sugar.

Now, 1 cup of white sugar require brown sugar = $\frac{\frac{3}{4} }{\frac{2}{3} } cups$

= $\frac{3}{4} \times \frac{3}{2} = \frac{9}{8} \ cup$

Thus, we can say $\frac{9}{8}$ = 1 1/8 cup of brown sugar is required per cup of white sugar.

Elodia [21]

Answer:

$6:5$

Step-by-step explanation:

Let $a$ be the length of the longer side of the smaller rectangle and $b$ be the length of the shorter side of the smaller rectangle

When you look at the combined rectangle from top to bottom, you can see that $3a=l$ . Therefore, $a=\frac{1}{3}l$

This is the same for $4b=l$ . Thus, $b=\frac{1}{4}l$

When you look from right to left, you can see that $w = 2b+a$ . Using this, we can represent $w$ in terms of $l$ .

$w=\frac{1}{2}l+\frac{1}{3}l\\\\w=\frac{5}{6}l$

Now, we can find the ratio of $l:w$ :

$l:\frac{5}{6}l\\\\1:\frac{5}{6}\\\\6:5$

This question was quite hard to explain.

If you have any questions about the solution, feel free to ask.

Please have a look at the diagram below to get a better understanding of the solution.

The circumference of the ellipse approximate. Which equation is the result of solving the formula of the circumference for b?

Serhud [2]

Answer:

$b = \sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}}$

Step-by-step explanation:

Given - The circumference of the ellipse approximated by $C = 2\pi \sqrt{\frac{a^{2} + b^{2} }{2} }$ where 2a and 2b are the lengths of 2 the axes of the ellipse.

To find - Which equation is the result of solving the formula of the circumference for b ?

Solution -

$C = 2\pi \sqrt{\frac{a^{2} + b^{2} }{2} }\\\frac{C}{2\pi } = \sqrt{\frac{a^{2} + b^{2} }{2} }$

Squaring Both sides, we get

$[\frac{C}{2\pi }]^{2} = [\sqrt{\frac{a^{2} + b^{2} }{2} }]^{2} \\\frac{C^{2} }{(2\pi)^{2} } = {\frac{a^{2} + b^{2} }{2} }\\2\frac{C^{2} }{4(\pi)^{2} } = {{a^{2} + b^{2} }$

$\frac{C^{2} }{2(\pi )^{2} } = a^{2} + b^{2} \\\frac{C^{2} }{2(\pi )^{2} } - a^{2} = b^{2} \\\sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}} = b$

∴ we get

$b = \sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}}$
