What is surface area?The area is the sum of the areas of all its faces.
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

Samir and Christian had a total of 360 marbles Samir lost 28 marbles while Christian brought 18 more marbles both of them had an equal number of marbles in the end how many marbles did Samir have at the beginning
Step-by-step explanation:
Marbles altogether = 360
Marbles Samir Lost = 28
360 - 28 = 332
Marbles Christian bought 18
332 + 18 = 350
Marbles both had in the end = 350 ÷ 2 = 175
Marbles Samir have at the beginning = 175 + 28 = 203
Answer = 203

Answer:
49 units
Step-by-step explanation:
The units on the other 3 sides (this is excluding the slanted portion ofc.)
would add up to 36.
Now you only left with doing the slanted portion of the shape. We must use pythagorean theorem to solve for the slanted portion. The longer leg, 12 units long. Just count from the point (18,4) and then stop at (18,16) it stops on the same line as the point (13,16)
Leg B=12
Leg A=5
Leg C=?
[tex]a^2+b^2=c^2[/tex]
25+144=196
Then square root 169. You will get 13
36+13=49
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)

A facilities manager at a university reads in a research report that the mean amount of time spent in the shower by an adult is 5 minutes. He decides to collect data to see if the mean amount of time that college students spend in the shower is significantly different from 5 minutes. In a sample of 8 students, he found the average time was 5.55 minutes and the standard deviation was 0.75 minutes. Using this sample information, conduct the appropriate hypothesis test at the 0.05 level of significance. Assume normality.
Answer:
0.0384 < 0.05, which means that we can conclude that the mean amount of time that college students spend in the shower is significantly different from 5 minutes.
Step-by-step explanation:
A facilities manager at a university reads in a research report that the mean amount of time spent in the shower by an adult is 5 minutes.
This means that the null hypothesis is [tex]H_{0} = 5[/tex]
He decides to collect data to see if the mean amount of time that college students spend in the shower is significantly different from 5 minutes.
This means that the alternate hypothesis is [tex]H_{a} \neq 5[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
Null hypothesis:
Tests [tex]H_{0} = 5[/tex], which means that [tex]\mu = 5[/tex]
In a sample of 8 students, he found the average time was 5.55 minutes and the standard deviation was 0.75 minutes.
This means, respectively, that [tex]n = 8, \mu = 5.55, \sigma = 0.75[/tex]
Test statistic:
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{5.55 - 5}{\frac{0.75}{\sqrt{8}}}[/tex]
[tex]z = 2.07[/tex]
Pvalue:
Since we are testing if the mean is different from a value, and z is positive. The pvalue is two multiplied by 1 subtracted by the pvalue of z = 2.07.
z = 2.07 has a pvalue of 0.9808
2*(1 - 0.9808) = 2*(0.0192) = 0.0384
Decision:
0.0384 < 0.05, which means that we can conclude that the mean amount of time that college students spend in the shower is significantly different from 5 minutes.
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.

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].

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.
