A box of stuffing costs $1.99 for 16 oz. Find the unit cost, round to the nearest hundredth.
Misha Larkins [42]

The given ratio is:

\frac{\text{ \$1.99}}{16oz}

To find the unit cost per ounce, we can use proportions as follows:

\frac{\text{ \$1.99}}{16oz}=\frac{x}{1oz}

Now, solve for x:

\begin{gathered} x=\frac{1oz\cdot\text{ \$1.99}}{16oz} \\ x=0.12 \end{gathered}

The cost per ounce (unit cost) is then $0.12/oz

Answer:

Each base angle is 81°

Step-by-step explanation:

A pennant is in the shape of an isosceles triangle and the vertex angle is 18°.

An iscosceles triangle has two equal sides and two equal angles.

So assuming the base angles measure b° each;

b° + b° + 18° = 180° (angles in a triangle add up to 180°)

2b° = 180° - 18° = 162°

b = 162° ÷ 2 = 81°

So each base angle is 81°

Alan just got a Fall job. The equation P = 12.50h represents the salary P (in dollars) he will earn when he works h hours. How m
balandron [24]

Given:

Alan salary P (in dollars) when he works h hours is represented by the equation

P=12.50h

To find:

The earning per hour.

Solution:

We have,

P=12.50h

Here, P is total salary and h is number of hours he works.

\text{Earning per hour}= \dfrac{\text{Total salary}}{\text{Number of hours}}

\text{Earning per hour}= \dfrac{12.50h}{h}

\text{Earning per hour}=12.50

Therefore, the earning per hour is $12.50.
