A rectangular swimming pool has a volume of 2160 cubic feet. Water is being added to pool at a rate of about 20 cubic feet per minute. Use an equation in point-slope form to determine about how long it will take to fill the pool completely if there were already about 1200 gallons of water in the pool. Use the fact that 1 cubic foot of space holds about 7.5 gallons of water.

Answers

Answer 1

1200÷7.5= 160
-> there is already 160 cubic ft. of water
y=20x+160
-> this is the equation
2160=20x+160
2000=20x
100=x
you need 100 cubic ft. more to finish filling the pool

On a adventure trail, you biked 12 mi, walked 4 mi, ran 6 mi, and swam 2 mi. What fraction of the total distance did you bike? Write this number as a decimal.

Answers

First you want to add all of those together.
12 + 4 + 6 + 2 = 24
So there are 24 miles in total.
Next, it says she biked 12 miles so you make a fraction.
12 / 24 which can be reduced to 1/2.
She spent one half of the total distance biking.
Hope this helps!

You biked 1/2, or 0.5, of the total distance on the adventure trail. The total distance covered was 24 miles.

To calculate the fraction of the total distance that you biked, we first need to determine the total distance covered in the adventure trail.

Biking: 12 milesWalking: 4 milesRunning: 6 milesSwimming: 2 miles

Adding these distances together gives us a total distance of:

Total Distance = 12 + 4 + 6 + 2 = 24 miles

The fraction of the distance biked is then given by the biking distance over the total distance:

Fraction Biked = 12 miles / 24 miles = 1/2

To express this fraction as a decimal, we perform the division:

Decimal Form = 1 ÷ 2 = 0.5

Therefore, you biked 1/2 (or 0.5) of the total distance.

For AB to be parallel to DC based on the diagram, angle AWZ must be equal to angle WZY.

Sherman hopes to get at least a 90 average on his science test. He has one more test before the end of the year. His past test scores are 79, 94, 91, and 92.Write and solve an inequality that represents the situation. What is the lowest score Sherman can get on his final test and reach his? show your work

Answers

(79 + 94 + 91 + 92 + x) / 5 > = 90
(356 + x) / 5 > = 90
356 + x > = 90 * 5
356 + x > = 450
x > = 450 - 356
x > = 94 <=== Sherman can get the lowest score at 94

Answer:

94 points

Step-by-step explanation:

The mean is defined by the sum of the numbers divided by how many numbers there are, so:

[tex]\frac{(79+94+91+92+x)}{5}>=90\\\\\frac{(356+x)}{5}>=90[/tex]

Multiplying both sides by 5

[tex](356+x)>=450[/tex]

Subtracting 356 on both sides:

[tex]x>=94[/tex]

So Sherman has to obtain at least 94 points on his final test in order to get an average of at least 90.

350$ at 3% for 10 years. What Is the
Interest earned?

Answers

If you are using continuous compound interest, the formula is A = Pe^RT where A= amount, P= principal value, R = the rate, and t = time. E is an actual number that is kinda hard to explain but it's just a button on the calculator.

In this case the equation would be A = 350e^(0.03)(10). This gives you approximately 472.4506 or approximately $472.45 since it's money and you round to the nearest penny.

the answer is $472.45

<5 and <6 are vertical angles and m<5=33° find m<6

Answers

Answer: m∡6 = 33°.
________________________________________________
Since all vertical angles are congruent and have EQUAL measurements,

and ∡5 and ∡6 are vertical angles;

then, m∡5 = m∡6 .
________________________________________________
So; given m∡5 = 33° ; m∡6 = 33° .
________________________________________________

The measure of the angle 6 is 33°.

Given that, ∠5 and ∠6 are vertical angles and m∠5=33°.

What are vertical angles?

Vertical angles are formed when two lines meet each other at a point. They are always equal to each other.

As we know, the vertical angles are congruent.

So, ∠5 = ∠6

⇒ ∠6 = 33°

Therefore, the measure of the angle 6 is 33°.

when writing an exponential function, how do you put 12.5% into a decimal.... for example 20% goes into .20 but how would I do that for 12.5? please help!

Answers

Remember that 1% is equivalent to 1 hundredth, or 0.01. What does 0.5% mean, then? Well, it's 0.5 hundredths, or five-tenths of a hundredth.

If we look at that in terms of fractions, that translates to:

[tex] \frac{5}{10}\times \frac{1}{100} = \frac{5}{1000}[/tex]

So, 0.5% is five thousandths, or 0.005, as a decimal. Combining that with 12%, which is 0.12 or twelve hundredths as a decimal, we have:

12.5% = 0.12 + 0.005 = 0.125

A rabbit can run short distances at a rate of 35miles per hour.a fox can run short distances at a rate of 21 miles per half hour.which animal is faster,and by how much?

Answers

The fox is faster. This means that while the rabbit can run at a rate of 35 miles per hour, the fox runs 42 miles per hour. Therefore, the fox runs 7 more miles per hour than the rabbit.

Since the fox's rate is based on half an hour and the rabbit's rate is based on a whole hour, you would need to create an equation that is spanned on the same amount of time.

To do this you would, simply, multiply the fox's rate by 2.

21 x 2 = 42
[tex] \frac{1}{2} [/tex] x 2 = 1

42 mi/1 h

A fox can run 7 miles per hour faster than a rabbit can.
