Katy has 1 3/8 cups of flour. Her cookie recipe calls for 2 cups of flour. How many more cups of flour does she need for the rec

AleksAgata [21]

Subtract the amount you have from the amount you need:

2 cups - 1 3/8 cups

Subtract the whole cup first:

2 cups -1 cup = 1 cup

8/8 = 1

Rewrite 1 as 8/8 then subtract the 3/8 you have:

8/8 - 3/8 = 5/8

You need 5/8 cup more

Find the area of a rhombus with side length 6 and an interior angle with measure $120^\circ$.

Serhud [2]

Answer:

The area of a rhombus is $18\sqrt{3}$ square units.

Step-by-step explanation:

Side length of rhombus = 6 units.

Interior angle of rhombus = 120°

another Interior angle of rhombus = 180°-120° = 60°.

Draw an altitude.

In a right angled triangle

$\sin \theta=\frac{opposite}{hypotenuse}$

$\sin (60)=\frac{h}{6}$

$\frac{\sqrt{3}}{2}=\frac{h}{6}$

Multiply both sides by 6.

$3\sqrt{3}=h$

The height of the rhombus is $3\sqrt{3}$ .

Area of a rhombus is

$Area=base\times height$

$Area=6\times 3\sqrt{3}$

$Area=18\sqrt{3}$

Therefore, the area of a rhombus is $18\sqrt{3}$ square units.
