Answer:

365ft^2

Step-by-step explanation:

So... First you take not that the 8ft on the right of the parallelogram has two lines indicating that the other side is the same distance. Cut both sides off making two of the same triangles. 7ft * 8ft = 56ft^2. 56ft^2 divided by 2 makes 28ft^2. But because there is two of them you would double it back to 56ft^2.

56ft^2

Then you would do 12ft * 7ft to get the rectangle. 12*7 makes 84. 84ft^2

84ft^2

Then you take note that on the bottom there is a line that is the same on each four sides making that a square. So all sides are the same. 15ft*15ft = 225ft^2

225ft^2

So now you add them all up to make 365 ft^2

Which is the final answer

Hope this helps! :)

Answer:

  determine the limit as x → ±∞

Step-by-step explanation:

If the function is a rational function, the horizontal asymptote will be the value of the ratio of the highest-degree terms in the numerator and denominator.

If the function is an exponential function, the horizontal asymptote will be the function value when the exponential factor is zero.

In the general case, you will need to determine the limit(s) of the function as the magnitude of the value of the independent variable gets large (tends toward infinity).

Answer:

To find horizontal asymptotes: If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0). If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.

Step-by-step explanation:

Let the cubic meters of gravel = x

Set up the equation:

4000 + 1500x = 18,000

Now solve for x:

4000 + 1500x =  18000

Subtract 4000 from both sides:

1500x = 14000

Divide both sides by 1500:

x = 14000/1500 = 140/15 = 28/3

Answer: 28/3

Answer:

The bacteria would be 1 half of 1,000,000.

Step-by-step explanation:

If it decreases by 1/2 each following hour, after 2 hours there would  be no bacteria left.

The population of bacteria after 6 hours will be equal to 31250 and the sequence followed here is a geometric sequence.

It is given that bacteria population is 1000000 and it decreases by a factor of 1/2 per hour.

We have to find out the bacteria left after 6 hours and also if this sequence is a geometric sequence or not.

What do you mean by geometric sequence ?

A geometric sequence is the sequence which is made by multiplying by the same value each time i.e., 2 , 4 , 8 , 16 where each time numbers are multiplied by a common factor 2.

As per the question ;

A bacteria population = 1000000

It decreases by a factor of 1/2 per hour.

So ;

After 1 hour population will be ;

= 1000000

After 2 hour population will be ;

= 1000000 × [tex]\frac{1}{2}[/tex]

= 500000

After 3 hours population will be ;

=  500000 × [tex]\frac{1}{2}[/tex]

= 250000

After 4 hours population will be ;

= 250000 × [tex]\frac{1}{2}[/tex]

= 125000

After 5 hours population will be ;

=  125000 × [tex]\frac{1}{2}[/tex]

= 62500

After 6 hours population will be ;

= 62500 × [tex]\frac{1}{2}[/tex]

= 31250

And

because from the second term , the ratio of each term to previous term is same i.e., 1/2. So this is a geometric sequence.

Thus , the population of bacteria after 6 hours will be equal to 31250 and the sequence followed here is a geometric sequence.

Answer:

solution

Let x = width

length = 10x-28 (28 feet less than 10 times its width)

A=l*w

A=(10x-28)

902=10x^2-28x

10x^2-28x-902=0

(10x-41) (10x+22)=0

10x-41=0

10x=41

x=41÷10

x=4.1

Now,

Length =28(4.1)-10

Therefore length =104.8

(Hope this is correct <3)

The length of the rectangle will be 104.8 feet.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

Given that a rectangle has a length of 28 feet less than 10 times its width. If the area of the rectangle is 902 square feet

The length of the rectangle will be calculated as below:-

Let x = width

Length = 10x-28 (28 feet less than 10 times its width)

A= L x w

A=(10x-28)

902=10x²-28x

10x²-28x-902=0

(10x-41) (10x+22)=0

10x-41=0

10x=41

x=41÷10

x=4.1

The length will be calculated as below:-

Length  = 28(4.1)-10

Length  = 104.8

Therefore, the length of the rectangle will be 104.8 feet.

Bonjour,

5+5+5 = 15

6+6+6 = 18

6+6 + (5+6+3) *3  = 12 +14*3= 12+ 42 =  54

Answer:

54

Step-by-step explanation:

The man represents 5, because three of him are fifteen (15 ÷ 3 = 5). The mask represents 3, because three of it are 9 (9 ÷ 3 = 3). The dümbbell represents 6, because three of it are eighteen (18 ÷ 3 = 6).

So, 2 dümbbells + (1 man + 1 mask + 1 dümbbell) × 1 mask

= 2(6) + (5 + 3 + 6) × 3

= 12 + 14 × 3

= 12 + 42

Answer:

Step-by-step explanation:

No, the results are not necessarily representative of the school as a whole.

A random survey is a research technique that is used to gather information from a sample of people or things in a population. The results of a random survey are more likely to be representative of the population as a whole since every member of the population has an equal chance of being chosen to take part in the research.

Given:

Ivy randomly surveys students in her school to learn more about mobile phone password use.

Of 25 respondents, 14 use a password.

If the survey was conducted on a volunteer basis, it is possible that the respondents who chose to participate may have different characteristics or behaviors than those who did not participate.

This could lead to a biased sample that does not accurately represent the entire school population.

Additionally, even if the sample is representative of the school population, a sample size of 25 is relatively small, which can increase the margin of error and make it more difficult to draw accurate conclusions.

Therefore, it is important to consider the limitations of the survey method and sample size when interpreting the results.
