The diameter of a circle is 18m . Find its circumference in terms of pi?
Answer:
The circumference of a circle =πd = π×18 =18π m
The diameter of a circle is 18 m. Find its circumference in terms of π.
Solution:-Diameter of a circle = 18 m. (Given)
Radius (r) of a circle = 18/2 = 9 m.
We know,
[tex] \dag [/tex] Circumference of a circle is 2πr.
So, It's circumference is (2 × π × 9) m.
It's circumference is 18π m.
It's circumference in terms of π is 18π m. [Answer]NO LINKS!! PLSS HELP ME I WILL GIVE YOU BRAINLYEST!!
Mr. Hernandez bought 16 meters of
chain-link fencing. The section of his yard that
needs to be fenced is 50 feet long. Did Mr.
Hernandez buy enough fencing? Determine the
number of feet Mr. Hernandez still needs to buy
or how many extra feet he has purchased.
(1 meter = 3.28 feet.)
Answer:
well yes he has 2.4 extra
Step-by-step explanation:
1 meter is 3.28 feer so 3.28 x 16 is 52.4 and he only need 50.
hoped this hlepd and you have to give me brailyest. i just want to help...
Answer:
yes
Step-by-step explanation:
well we can just multiply the 3 with the 16
well now we have 48
add 28, 16 times which gives us 4.48
48+4.48 52.48
you have 2.48 feet left
and yes he has enough

What two numbers multiply to get 18 but add to get -12
Answer:
-6+3[tex]\sqrt{2}[/tex] and -6-3[tex]\sqrt{2}[/tex]
Step-by-step explanation:
xy = 18
x+y = -12
y = -12-x
substitution method:
x(-12-x) = 18
-12x - x² - 18 = 0
-x² - 12x - 18 = 0
-(x² + 12x + 18) = 0
used quadratic formula:
(-12±√144 - 4(18)) ÷ 2
(-12 ± [tex]\sqrt{72}[/tex]) ÷ 2
(-12 ± 6[tex]\sqrt{2}[/tex]) ÷ 2
= -6 ± 3[tex]\sqrt{2}[/tex]

Find the GCF of each pair of monomials.
48t, 60st
Answer:
The GCF is 12t
Step-by-step explanation:
Here, we want to calculate the greatest common factor of the given polynomials
To do this, we need to write each as the product of its prime factors
We have this as;
48t = 2 * 2 * 2 * 2 * 3 * t
60st = 2 * 2 * 3 * 5 * s * t
we then bring out pairs of similar terms
So the GCF would be;
2 * 2 * 3 * t = 12t
p is an odd number.
Explain why p^2 +1 is always even number
Answer:
every odd number that squares up and add 2 will give an even answer
Answer:
see explanation
Step-by-step explanation:
Given that p is an odd number , then
p² is always an odd number
Adding 1 to an odd number gives an even number.
So p² + 1 is always even for p odd
A salesman who is on the road visiting clients thinks that, on average, he drives the same distance each day of the week. He keeps track of his mileage for several weeks and discovers that he averages 122 miles on Mon- days, 203 miles on Tuesdays, 176 miles on Wednesdays, 181 miles on Thursdays, and 108 miles on Fridays. He wonders if this evidence contradicts his belief in a uni- form distribution of miles across the days of the week. Explain why it is not appropriate to test his hypothesis using the chi-square goodness-of-fit test.
Answer:
The conditions are not met.
Step-by-step explanation:
The conditions for the chi square test for goodness of fit are
1) the sample is a random sample
2) the variable under study is categorical
3) all expected value of the number of sample observations are greater or equal to 5.
A)The observations must be independent
B) for 2 categories the expected values must be at least 5
C) for the 3 categories the expected values must be at least 1 and no more than 20% may be smaller than 5
The observations given may not be independent i.e have equal chances of occurrences or are maybe dependent on each other in the sense that there maybe a limit for his traveling mileage or the a limit for petrol ( fuel ) usage . So if he is required to drive 500 miles in a week each day mileage depends on the other day mileage .
Also we are given the information that keeps track of his mileage for several weeks, but we are not sure if several refers to more than 5 .
As both conditions are not clearly satisfied it is not appropriate to test his hypothesis using the chi-square goodness-of-fit test.
The sample must also be a random sample.
Here he has taken the mean of all the days.

In the diagram, y= x-15 and z=125. What is the value of x?
Answer:
x = 70
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
z is ab exterior angle of the triangle , then
x + y = z , that is
x + x - 15 = 125
2x - 15 = 125 ( add 15 to both sides )
2x = 140 ( divide both sides by 2 )
x = 70

Five angles of a hexagon measures 119, 129,104,139 and 95 degrees. What is the measure of the sixth angle?
Answer:
x = 134
Step-by-step explanation:
Given that,
Five angles of a hexagon measures 119, 129,104,139 and 95 degrees.
We know that,
The sum of interior angles of a hexagon must equal 720 degrees.
So,
119+129+104+139 +95+x = 720
Where
x is the sixth angle
So,
586+x=720
x = 720-586
x = 134
So, the sixth angle is equal to 134.

The surface area of the red square is 180, and the surface area of the blue square is 328. So the full answer is 508.
Step-by-step explanation:
A = 2( width times length +height times length +height times width ) = 2(6 times 3 + 8 times 3 + 8 times 6)=180
A = 2(width times length + height times length + height times width) = 2(2 times 12 + 10 times 12 + 10 times 2) = 328
And 328 + 180 = 508.

Answer: The mean is 6.
Step-by-step explanation: First you add all of the numbers together getting a total of 48. Next to find the mean you divide them by the total number of "dots". Lastly, you get the answer of 6 which is your mean.
Answer:
6.
Step-by-step explanation:
First you take the data on the dot plot, and write the numbers down from least to greatest.
The data set:
2,3,6,6,7,8,8,8
Now that you have the data reordered in a easier way to read, add up all the numbers that you got from the dot plot.
2+3+6+6+7+8+8+8=48
Next we count all the number in the data set we made.
2,3,6,6,6,7,8,8,8 = 8
The amount of numbers in this data is 8.
Lastly we then divide 48 by 8.
48/8= 6
So your answer is 6!
A man invests $16800 in a savings plan that pays simple interest at a rate of 5% per annum. Find the time taken for his investment to grow to $19800.
Answer: 3.57 years
Step-by-step explanation:
Based on the question given, the interest is the difference between the amount and the principal which will be:
= $19800 - $16800
= $3000
The formula for Simple interest is given as:
Interest = Principal × Rate × Time
3000 = 16800 × 5% × Time
3000 = 16800 × 0.05 × Time
3000 = 840 × Time
Time = 3000 / 840
Time = 3.57
The time taken to grow the investment is 3.57 years
