The areas of the base, top, and lateral surfaces i.e all sides of the object. It is measured using different area formulas and measured in square units and then adding all the areas.The area of a solid object is a measure of the total area that the surface of the object covers.
area of the pool = 8 * 28 meteres²
total area of pool and path = 800 meteres ²
The width of the path is = 800 - 224

(75 hundredths) + (4 x 100) + (67 ones) + (5 tens) 2. Rocky's rug is in the shape of a rectangle. The width of the rug is 2 feet. The length of the rug is 4 feet. Enter the area, in square feet, of Rocky's rug.
Answer:
[tex]A=8\ feet^2[/tex]
Step-by-step explanation:
Given that,
The width of the rug is 2 feet.
The length of the rug is 4 feet.
We need to find the area of the rug. Fo a rectangle shape, the area of the rectangle is given by :
A = lb
So,
[tex]A=2\times 4\\\\A=8\ feet^2[/tex]
So, the area of the rug is [tex]8\ feet^2[/tex].
if the area of the field is 16b^2+60b-100 and one dimension is b+5, what would be the other dimension?
Answer:
[tex]l=16(b-1.25)[/tex]
Step-by-step explanation:
Given that,
The area of the field is [tex]16b^2+60b-100[/tex]
One dimensions = (b+5)
The field is in the shape of a rectangle whose are is given by :
A = lb
Wher
l is the length or the other dimension
[tex]l=\dfrac{A}{b}\\\\l=\dfrac{16b^2+60b-100}{b+5}\\\\l=\dfrac{(16(b+5)(b-1.25)}{b+5}\\\\l=16(b-1.25)[/tex]
So, the other dimension be [tex]16(b-1.25)[/tex].
Snow Play Ski Park costs $35 entry fee and then $5 per hour. If you have $60, how long can you be at Snow Play Ski Park?
Part A - Identify the independent and dependent variables.
Answer:
You can be in the snow play ski park 5hours
Step-by-step explanation:
First 60$ - 35$=25$
1h=5$
2h=10$
3h=15$
4h=20$
5h=25$
So you can pay 35$ for the snow play ski park and then you can be there 5hours.So 35$ for the entry+25$ for the 5 hours=60$

Previously, an organization reported that teenagers spent of 4.5 hours per week, on average, on the phone. The organization thinks that, currently, the mean is higher. Fifteen randomly chosen teenagers were asked how many hours per week they spend on the phone. The sample mean was 4.75 hours with a sample standard deviation of 2.0.
Required:
Conduct a hypothesis test.
Answer:
There is no significant evidence to conclude that the mean hours spent per week by teenagers is greater than 4.5
Step-by-step explanation:
H0 : μ = 4.5
H1 : μ > 4.5
Sample size, n = 15 ; sample, mean, xbar = 4.75 ; sample Standard deviation, s = 2.0
Test statistic : (xbar - μ) ÷ s/sqrt(n)
Test statistic : (4.75 - 4.5) ÷ 2/sqrt(15)
Test statistic : 0.25 / 0.5163977
Test statistic = 0.484
Using the test statistic to obtain the Pvalue :
Using α = 0.05, df = 15 - 1 = 14
Pvalue = 0.3179
Since, Pvalue > α ; we fail to reject the Null.
We conclude that ;
There is no significant evidence to conclude that the mean hours spent per week by teenagers is greater than 4.5

An explicit function to represent the data is [tex]f(n)=5(3)^{n-1}[/tex], f(5)=405. Therefore, option C is the correct answer.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Using [tex]y=a(b)^x[/tex], where a is x-intercept and b is the growth factor
The points started from n = 1 not zero and initial value found when the exponent = 0
So, the exponent must be n-1
Here, a=5
So, [tex]y=5(b)^{x-1}[/tex]
Substitute (x, y)=(2, 15) in above obtained equation
That is, [tex]15=5(b)^{2-1}[/tex]
⇒ b=3
Now, the function is [tex]y=5(3)^{x-1}[/tex]
So, [tex]f(n)=5(3)^{n-1}[/tex]
Now, [tex]f(5)=5(3)^{5-1}[/tex]
⇒ [tex]f(5)=5\times81[/tex]
⇒ [tex]f(5)=405[/tex]
An explicit function to represent the data is [tex]f(n)=5(3)^{n-1}[/tex], f(5)=405. Therefore, option C is the correct answer.

Write the decimal in simplest fractional form: 3.05
Answer:
The simplest form, as a fraction is:
[tex]\frac{61}{20}[/tex]
Step-by-step explanation:
Though being quite a large amount, this is actually its number, here is why:
3.05 turned into a fraction would look like a mixed fraction:
[tex]3\frac{5}{100}[/tex]
It is [tex]\frac{5}{100}[/tex] because 0.05 is also 5 hundredths.
And 3 is 3.00 because it is a whole number.
Now, you need to reduce or simplify the [tex]\frac{5}{100}[/tex] into:
[tex]\frac{5}{100}[/tex] = [tex]\frac{1}{20}[/tex]
The reason it is [tex]\frac{1}{20}[/tex] is because:
[tex]\frac{5}{100}[/tex]
Both the numerator (top of fraction) and denominator (bottom of fraction) can both be divided by 5, which gives you your total of:
[tex]\frac{1}{20}[/tex]
Now, you are left with:
[tex]3\frac{1}{20}[/tex]
But since we are looking for the most simplest fractional form, and not the mixed form, we will need to turn this into a improper fraction.
Which will look like:
[tex]\frac{61}{20}[/tex]
This is how I turned it from a mixed fraction into a improper fraction:
[tex]3\frac{1}{20}[/tex]
(First, multiply 3 by the denominator, which is 20)
3 · 20
= 60
You will now add 1 to 60 and get a sum of:
60 + 1
= 61
(The reason you want to multiply 20 and 3, is because if you have the whole of a denominator, for example:
[tex]\frac{20}{20}[/tex]
it will equal 1, in this case:
if we have 3:
[tex]\frac{20}{20}[/tex] [tex]\frac{20}{20}[/tex] [tex]\frac{20}{20}[/tex]
Then our whole number will be 60 for our numerator and it will look like:
[tex]\frac{60}{20}[/tex] = 3
[tex]3\frac{1}{20} = \frac{61}{20}[/tex]
These are actually the same, just in different fractional forms.
From here we will check if we can make
[tex]\frac{61}{20}[/tex] and more simplified...
I have checked that this is most simplest form, so your answer is:
[tex]\frac{61}{20}[/tex]

What is the equation of the line that passes through the point (5, -6) and has a
slope of 3/5
Answer:
y = 3/5x + -9
or y = 3/5x - 9
Step-by-step explanation:
Since you are already given the slope for this equation all you have to do is plug in the ordered pair in this equation: y = mx+b
Here is what this equation stands for:
y = the y in the order pair you are given, in this case it would be -6
m = This is the slope, sometimes you may not be given the slope so you would have to find it, but in this case, you are given it, the slope is 3/5
x = the x in the ordered pair you are given, in this case it would be 5
b = This is the y-intercept, you will mostly be solving for this most of the time
(5,-6)
(x, y)
y = mx+b (Use this Formula)
-6 = 3/5(5) +b (The numbers have been substituted within the formula)
-6 = 3+b (simplify the equation by multiplying the slope by the x)
-6-3 = b ( once simplified the left side of the equation, go to the right side, but remember when you do that you have to change the sign because you are eliminating 3 on the left side completely, "what you do on one side, do it to the other side")
-9 = b (solve)
y = 3/5x + -9 (plug in the slope and B(y-intercept) within the formula - y = mx+b, make sure that you are not plugging in x and y for this step)

1. The pollution level in the center of a city at 6 am is 30 parts per million and it
grows in linear fashion by 25 parts per million every hour. If y is pollution
and t is time elapsed after 6 am, determine:
a. The equation that relates y with t.
b. The pollution level at 4 o'clock in the afternoon
Answer:
a) [tex]y(t) = 30 + 25t[/tex]
b) The pollution level at 4 o'clock in the afternoon is of 280 parts per million.
Step-by-step explanation:
The pollution level in the center of a city at 6 am is 30 parts per million and it grows in linear fashion by 25 parts per million every hour.
This means that the pollution in t hours after 6 am is given by:
[tex]y(t) = 30 + 25t[/tex], which is the answer to question a.
b. The pollution level at 4 o'clock in the afternoon
4 in the afternoon is 10 hours after 6 am, so this is y(10).
[tex]y(10) = 30 + 25*10 = 30 + 250 = 280[/tex]
The pollution level at 4 o'clock in the afternoon is of 280 parts per million.
Q4. Three students A, B and C had 3 soil samples. Each student poured 180 mL of water
into the soil samples they had. Time taken for the percolation of water through the three
soil samples was 25 min, 10 min and 40 min respectively. Which student had the soil with
the highest percolation rate?
Answer:
Student B
Step-by-step explanation:
Soil percolation is the porosity of soil to the downward flow of water through it. A soil with high percolation allows water to drain through it downwards in a less period of time.
From the given experiment by students, it takes 25 min for water to percolate through the soil sample of student A, 10 min for the soil sample of student B and 40 min for the soil sample of student C. Thus, the student that had the soil sample with highest percolation rate is B.

Leg B=12
