Given:

\text{ Dimension = 3}\times5

Sol:

Area of picture is:

\begin{gathered} =\text{ length}\times\text{ Width} \\  \\ =15 \end{gathered}

If the cost $10 per square inch then price of 15 square inch is:

\begin{gathered} =15\times10 \\  \\ =150 \end{gathered}

If the quadruple of dimension that mean:

\begin{gathered} \text{ l ength = 4 length} \\  \\ Width\text{ = 4 width} \end{gathered}

So area is:

\begin{gathered} A=4\text{ length}\times4\text{ Width} \\  \\ A=4(15) \\  \\ A=60 \end{gathered}

So price is:

\begin{gathered} =60\times10 \\  \\ =600 \end{gathered}

2− ​0.5n=3n+16<br><br> Help
Mariulka [41]
2 - 0.5n= 3n+16
-----------------------            subtract 2 from both sides
-2                   -2

-0.5n = 3n+14
-----------------------             then subtract -3n from both sides as well
-3n       -3n

-3.5n = 14
---------------                       divide -3.5 on each side
-3.5       -3.5
                                        simplify

Dara ran on a treadmill that had a readout indicating the time remaining in her exercise session. When the readout indicated 24
malfutka [58]

Answer:

The correct option is E. 16 min 12 sec.

Step-by-step explanation:

Consider the provided information.

When the readout indicated 24 min 18 sec, she had completed 10% of her exercise session.

That means 24 min 18 sec is 90% of her exercise time.

First convert the 24 min 18 sec into seconds:

24 min 18 sec = 1440+18 = 1458 seconds

Let x represents the 100%.

\frac{1458}{x}=\frac{90\%}{100\%}

x=\frac{1458}{0.9}

x=1620

That means the total time of workout was 1620 seconds or 27 minutes.

Now she had completed 40% of her exercise session, that means the readout will indicate 60% of the time.

Calculate the 60% of 1620 as shown:

1620\times \frac{60}{100}=972

Now convert 972 seconds into minutes as shown:

972 seconds = 960 seconds + 12 seconds = 16 min 12 seconds

Hence, the correct option is E. 16 min 12 sec.
