An outside thermometer reads -5 degrees at 8:00 a.m. By 12:30 p.m. the temperature outside has increased by 11 degrees. At 12:30
Lesechka [4]

Answer:

73 degrees.

Step-by-step explanation:

So, let's see the information provided in the question.

At 8 AM, the thermometer was reading -5 degrees.

At 12:30 PM, the temperature has increased by 11 degrees, so it's now +6 degrees outside.

Inside Susan's house, the temperature is 7 degrees more than 11 times the outside temperature, at 12:30 PM.

So, we know the outside temperature at 12:30 PM is +6 degrees.

11 times 6 = 66 degrees.

Then we add the additional 7 degrees, to get a total of 73 degrees.

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: X = kuv/ (u+v)

that means that x(u+v)/(uv) = k, a constant. so you want x such that,

x(3+3)/(3*3) = 3(3+1)/(3*1)

x=6
