The circumference of a circle is 13π m. What is the area, in square meters? Express your answer in terms of π π.
Answers
Answer:
13×(22/7)whole square
Answer:
42.25π
Step-by-step explanation:
The circumference is the diameter times pi.
This means that 13π/π=13 (the diameter)
The radius is diameter/2, so it is 13/2 which is 6.5
The area is the radius squared times pi
6.5^2 = 42.25
42.25π is the area

Solve -36 = j + 13 for j .
Answers
Answer:
J = -49
Step-by-step explanation:
Answer:
x=-49
Step-by-step explanation:
-36=j+13
first we need to get j by itself so we need to move 13 from the right side to left by subracting 13 from both sides.
-36-13=j+13-13
-49=j
since J is alone that is the answer

Step-by-step explanation:
when 2 lines intersect, the angles on both sides of either one of the lines midst be the same, of course (where would other angles come from ? we are dealing with straight lines). they are only left-right mirrored.
therefore,
5x = 3x + 60
2x = 60
x = 30
so, both angles are 5×30 = (3×30 + 60) = 150°

The length of a cell phone is 1.21.2 inches and the width is 4.64.6 inches. The company making the cell phone wants to make a new version whose length will be 1.141.14 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?
Answers
Answer:
The width of the new phone will be 4.37 inches
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value.
The original length of a cell phone was L=1.2 inches and the original width was 4.6 inches.
A new version of the cell phone is to be released with proportional dimensions with respect to the original cell phone.
We are given the length of the new phone L'=1.14 inches. The ratio of the lengths is 1,2/1.14=1.053.
The new width should be W'=4.6/1.053=4.37 inches
The width of the new phone will be 4.37 inches

In a second period class, 37.5% of students like to bowl. in a fifth period class, 12 out of 29 students like to bowl. in which class does a greater fraction of the students like to bowl?
Answers
The fifth period class has a greater fraction of students that like to bowl.
Any number in the form of p/q where p and q are integers and q is not equal to 0 is a rational number. Examples of rational numbers are 1/2, -3/4, 0.3, or 3/10.
Here we have,
In second period, 37.5% students like to bowl
∴, 37.5% = 37.5/100
= 375/1000
= 0.375 students like to bowl in second period
And in fifth period, 12 students out of 29 like to bowl
Therefore, 12/29 = 0.413 students like to bowl in fifth period
Hence, on comparison
0.375 < 0.413
= 375/1000 < 12/29
Thus, fifth period class has a greater fraction of student that like to bowl as compared to second period class.

What expression represents the length of one side of the square?
Answers
Answer:
The expression representing length is (x+1).
Step-by-step explanation:
Area of square = [tex]1+2x+x^2[/tex]
We need to find length of square
We know that: [tex]Area\:of\:Square=(Length)^{2}[/tex]
Putting values and finding length
[tex]Area\:of\:Square=(Length)^{2} \\\\1+2x+x^2=(Length)^{2}\\(Length)^{2} = x^{2} + x +x +1\\(Length)^{2} = x( x+1) +1 (x +1)\\(Length)^{2} = (x+1)^{2}\\Length = (x+1)[/tex]
So, the expression representing length is: (x+1)

Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(150)?
f(150) represents the average number of days houses stay on the market before being sold for $150,000.
Houses sell on the market for an average of $150,000 and stay on the market an average of 150 days before being sold.
Houses sell for an average of $150,000.
f(150) indicates houses stay on the market an average of 150 days before being sold.
Answers
Answer:
This is the average number of days the house stayed on the market before being sold for $150,000.
Step-by-step explanation:
f(p) is defined as the average number of days a house stays on the market before being sold for price p (given in $1000).
We want f(150); this means p=150. Since p is in thousands of dollars, this means the price of the house was $150,000.
This means f(150) is the average number of days the house stayed on the market before being sold for $150,000.
Answer:
The statement that best describes f(150) is D
Step-by-step explanation:
D. f(150) indicates houses stay on the market an average of 150 days before being sold.
Because houses stay on the market for 150 days before being sold.

What is proportion?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Giovanni can read 250 words per minute.
and, books contain 400 pages
So, she can read the portion of book
=250/400
= 5/8 per minutes
= 5/8 x 60
=300/8
= 37.5 pages in one hour
and in 2 hours she can read
= 37.5 x 2
= 75 pages in two hours
