Given:

Rachel used $\dfrac{1}{3}$ of her savings to buy brushes.

She used $\dfrac{3}{5}$ of her savings to buy paint.

To find:

The fraction for remaining savings.

Solution:

Fraction that Rachel used of her savings to buy brushes and paint is

$\text{Fraction for used amount}=\dfrac{1}{3}+\dfrac{3}{5}$

$=\dfrac{5+9}{15}$

$=\dfrac{14}{15}$

Now,

$\text{Fraction for remaining savings}=1-\text{Fraction for used amount}$

$\text{Fraction for remaining savings}=1-\dfrac{14}{15}$

$\text{Fraction for remaining savings}=\dfrac{1}{15}$

Therefore, $\dfrac{1}{15}$ of her savings is remaining.

sin∅ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Define variables

∅ = 39°

opposite leg = 9

hypotenuse = x

Step 2: Solve for x

Substitute: sin39° = 9/x
Multiply x on both sides: xsin39° = 9
Isolate x: x = 9/sin39°
Evaluate: x = 14.3011
Round: x ≈ 14.30
