Hello there!

If Jessica uses 3 equal sizes for all three picture frames, and she only has 1/2 of a yard, one easier way that we can convert this would be that there are 0.5 = 18 inches of Ribbon.

18 ÷ 3 = 6 ... 6 × 3 = 18.

Your correct answer would be D. 6

Taylor is mixing fruit punch.The recipe calls for 2 tsp of sugar for each 8oz glass of punch . Taylor has a 3 gal punch bowl.How
dalvyx [7]

I would put it like this .


Let x be punch bowl

Ratio: (Sugar/glass)

(3) * (2/8) = x

6/8 = x

0.75= x

So you will need 3/4 cups of sugar



Or if easier for you cross multiply the set up same ratio so would look like .


2/8=x/3. Now do cross multiply


2×3=8×x


6=8x


Now divide


6/8=x


You will get 0.75 which is 3/4 cups

A = √7 + √c and b = √63 + √d where c and d are positive integers.
mrs_skeptik [129]

Answer:

\displaystyle a:b=\frac{1}{3}

Step-by-step explanation:

<u>Ratios </u>

We are given the following relations:

a=\sqrt{7}+\sqrt{c}\qquad \qquad[1]

b=\sqrt{63}+\sqrt{d}\qquad \qquad[2]

\displaystyle \frac{c}{d}=\frac{1}{9} \qquad \qquad [3]

From [3]:

9c=d

Replacing into [2]:

b=\sqrt{63}+\sqrt{9c}

We can express 63=9*7:

b=\sqrt{9*7}+\sqrt{9c}

Taking the square root of 9:

b=3\sqrt{7}+3\sqrt{c}

Factoring:

b=3(\sqrt{7}+\sqrt{c})

Find the ration a:b:

\displaystyle a:b=\frac{\sqrt{7}+\sqrt{c}}{3(\sqrt{7}+\sqrt{c})}

Simplifying:

\boxed{a:b=\frac{1}{3}}
