A recipe of salad dressing calls for ¼ cup vinegar to ⅔ cup oil. How many cups of oil are needed for each cup of vinegar?
Akimi4 [234]

Answer:

2\frac{2}{3} \ cups  of oil are needed for each cup of vinegar.

Step-by-step explanation:

Given:

A recipe of salad dressing calls for ¼ cup vinegar to ⅔ cup oil.

Now, to find the cups of oil are needed for each cup of vinegar.

So, we solve by using unitary method:

If  \frac{1}{4} cup of vinegar is needed for oil of \frac{2}{3} cup.

So, 1 cup of vinegar is needed for oil of = \frac{2}{3} \div\frac{1}{4}

= \frac{2}{3}\times 4  

(the fractions turns reciprocals as the division changes into multiplication)

= \frac{8}{3}

= 2\frac{2}{3} cups.

Therefore, 2\frac{2}{3} \ cups  of oil are needed for each cup of vinegar.

Answer: 133^{\circ}

Step-by-step explanation:

Opposite angles of a cyclic quadrilateral are supplementary, so:

4x+5+x+15=180\\\\5x+20=180\\\\5x=160\\\\x=32

This means that m\angle A=4(32)+5=\boxed{133^{\circ}}
