During a scuba dive, Lainey descended to a point 20 feet below the ocean surface. She continued her descent at a rate of 20 feet

per minute. Write an inequality you could solve to find the number of minutes she can continue to descend if she does not want to reach a point more than 100 feet below the ocean surface.

She can descend five minutes so that should help
Rainbow [258]3 years ago

Answer:

We know that she first descends 20 feet, and then she descends at a rate of 20 feet per minute. Basically, we have 20 feet which have to me summed with 20x, which expresses the ratio per minute, where x is minutes, and these terms cannot be more than 100 feet, so there are equal or less than 100 feet,

The expression would be:

20+20x\leq 100

If we solve this, we have

20+20x\leq 100\\20x\leq 100-20\\x\leq \frac{80}{20}\\ x\leq 4

Therefore, she cannot descent for more than 4 minutes.

(a^3+14a^2+33a-20)\(a+4)
Oksi-84 [34.3K]
Perhaps you meant   <span>(a^3+14a^2+33a-20)   /   (a+4), for division by (a+4).  

Do you know synthetic division?  If so, that'd be a great way to accomplish this division.  Assume that (a+4) is a factor of </span>a^3+14a^2+33a-20; then assume that -4 is the corresponding root of a^3+14a^2+33a-20.

Perform synth. div.  If there is no remainder, then you'll know that (a+4) is a factor and will also have the quoitient.

-4  /   1   14   33   -20
     ___    -4_-40    28___________
          1   10   -7       8

Here the remainder is not zero; it's 8.  However, we now know that the quotient is 1a^2 + 10a - 7 with a remainder of 8.

dalvyx [7]
So,

All we have to do is multiply all three dimensions together.

First, convert all fractions into improper fractions.

3 \frac{1}{5}--\ \textgreater \  \frac{16}{5}

1 \frac{3}{4} --\ \textgreater \  \frac{7}{4}

2 \frac{1}{4} --\ \textgreater \ \frac{9}{4}

Now multiply the fractions together.

<span>\frac{16}{5}*\frac{7}{4}*\frac{9}{4}= \frac{2*2*2*2*3*3*7}{2*2*2*2*5}
</span>
\frac{3*3*7}{5}--\ \textgreater \ \frac{63}{5}\ or\ 12 \frac{3}{5}\ ft.^3

The correct option is C.
