Question says that Isabelle is mixing red paint with blue paint to make purple paint.
She adds 3/10 of a fluid ounce of red to 11/16 fluid ounces of purple.
Now we need to find about how many fluid ounces of red will she need to make 3 fluid ounces of purple paint.
So let we need x fluid ounces of red color paint.
To find that we can setup ratio between quantity of red and pruple colour paints.
Hence final answer is 
fluid ounce of red colour.
Answer:62∘
Step-by-step explanation:
SOH-CAH-TOA
\cos U = \frac{\text{adjacent}}{\text{hypotenuse}}=\frac{2.2}{4.7}
cosU=
hypotenuse
adjacent
=
4.7
2.2
\cos U = \frac{2.2}{4.7}
cosU=
4.7
2.2
U=\cos^{-1}(\frac{2.2}{4.7})
U=cos
−1
(
4.7
2.2
)
U=62.09\approx 62^{\circ}
U=62.09≈62
∘
Actually it should be 4/1
Answer:
D
Step-by-step explanation:
