Answer:
x = 55.94 degrees
Step-by-step explanation:
(to find x, use cosine) (cos = )
<em>First step: write out the equation</em>
⇒ cos x =
<em>Second step: find out what </em><em> is </em>
⇒ = 0.56
<em>Third step: find out what the cos-1 of 0.56 is</em>
⇒ cos-1 of 0.56 = 55.94

x = 22/21 , y = 8/3
Step-by-step explanation:
Answer:
2.625 cups or 21 ounces
Step-by-step explanation:
Ava needs 3/4 cup of blue paint for every 1 cup of white paint. So, the ratio is 0.75 : 1.
She has 28 ounces of white paint. But, you have to convert ounces to cups.
1 cup = 8 ounces
28 ounces ÷ 8 ounces/cup = 3.5 cups
Now set up a ratio.
X (how much blue paint is needed) is over 3.5 cups (the amount of white paint she has)
Cross multiply and divide.
x = 0.75 × 3.5
x = 2.625 cups
To convert to ounces, multiply by 8.
2.625 cups × 8 ounces = 21 ounces
Therefore, Ava needs 2.625 cups or 21 ounces of blue paint.
Hope that helps.
