And object is traveling at a steady speed of 8 2/3 mph how long will it take to object to travel 5 1/5 miles

LenaWriter [7]

$\bf \begin{array}{ccll}
miles&hours\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
8\frac{2}{3}&1\\\\
5\frac{1}{5}&h
\end{array}\implies \cfrac{8\frac{2}{3}}{5\frac{1}{5}}=\cfrac{1}{h}\implies \cfrac{\quad \frac{26}{3}\quad }{\frac{26}{5}}=\cfrac{1}{h}\implies \cfrac{26}{3}\cdot \cfrac{5}{26}=\cfrac{1}{h}
\\\\\\
\cfrac{5}{3}=\cfrac{1}{h}\implies 5h=3\implies h=\cfrac{3}{5}$

which is just 36 minutes.

Which of the following describes the “p/2” in the expression above?

julia-pushkina [17]

Option B. Quotient is the right answer

Step-by-step explanation:

Given expression is:

p/2 +4(7+p)

Let us look at the options one by one

<u>A. factor</u>

p/2 is not a factor as the factor is always multiplied with another factor

<u>B. quotient</u>

This is the right answer as p is being divided by 2. The quotient of both will be used for further calculations

Hence,

Option B. Quotient is the right answer

What is the range of possible sizes for side x? _ < x < _

allochka39001 [22]

Answer:

0.5 < x < 16.5

Step-by-step explanation:

The third side of the triangle must be longer than the difference of the other two sides:

x > (8.5 -8.0)

x > 0.5

And it must be shorter than their sum:

x < (8.5 +8.0)

x < 16.5

The third side must be in the range ...

0.5 < x < 16.5

_____

These limits are a direct consequence of the triangle inequality, which requires the sum of the two shortest sides exceed the length of the longest side.
