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.

What are the solutions of the equation (2x + 3)^2 + 8(2x + 3) + 11 = 0? Use u substitution and the quadratic formula to solve.
Nana76 [90]
U=2x+3, x=u/2-3/2
u^2+8u+11=0
u1=(-8+sqrt(64-44))/2=-4+sqrt(5)
u2=-4-sqrt(5)
x1=u1/2-3/2=-7/2+sqrt(5)/2
x2=u2-3/2=-7/2-sqrt(5)/2
