The circumference of a circle is 125.6 millimeters. What is the circle's radius?
Answers
Answer:
20 millimeters.
Step-by-step explanation:
To find the radius of a circle with circumference, you must divide the circumference by pi (3.14).
After dividing the circumference by pi, you now have the diameter of the circle.
Secondly, to get the radius, divide the quotient (the diameter) by 2.
The quotient is the radius of the circle.
----------------------------------------------------------------------------------------------------------------
Now, I will repeat these steps using the circumference of 125.6 millimeters.
125.6 ÷ 3.14 = 40.
40 ÷ 2 = 20.
Therefore, 20 millimeters is the radius of this circle.
The circle's radius is mathematically given as

7. Kya picks up where she left off in her book and starts reading. After 2 hours, she's on page 195. After reading for 4 hours that day, she's on page 297. Write an equation to represent how many pages Kya reads per hour.
I did the equation= y=51x+93
There are a total of 399 pages in the book. How many more hours does Kya have left to read? PLEASE HELP WILL THIS PART I DONT UNDERSTAND
Answers
Answer:
Step-by-step explanation:
Work for finding the equation, feel free to skip it:
So first off, to write the equation, we will use an equation in slope intercept form: y = mx + b, where y is the numbers of pages she has read, m is the number of pages she reads per hour, x is the number of hours she read, and b is the number of pages she has already read.
To find the slope(The number of pages she reads per hour), we can subtract the number of pages she had read at 2 hours from the number of pages she had read at 4 hours:
297 - 195 = 102.
This tells us she read 102 pages over 2 hours. Thus, over 1 hour, she had read 102/2 = 51 hours. This is m. So our equation so far is y = 51x + b
To find b, we can take 195(the pages she had read after 2 hours), and subtract it by the pages she can read over 2 hours(51 * 2), giving us the amount of pages she had already read(b):
195 - (51*2) = 195 - 102 = 93.
So our equation is:
y = 51x + 93.
Work for finding how many hours it will take Kya to read the whole book:
Y is the total number of pages Kya has read when we plug in x hours. However, if we already know the total number of pages in a book, we can plug in that number for Y, and then solve for x to find how many hours it takes for Kya to read the book:
399 = 51x + 93
Subtracting 93 from both sides gets us:
51x = 306
=
x = 6
This means it takes 6 hours for Kya to read the whole book.
Since Kya has already been reading for 4 hours, the time she has left is:
6-4 = 2
So it takes Kya 2 more hours to finish reading the 399 pages in the book.
Hope this helps!

What should be done to these equations in order to solve a system of equations by elimination?
Answers
To solve the problem of a system of equations by elimination, we can start with both equations in standard form. Then we can decide which variable will be easier to eliminate.
How can we decide? We want to have the coefficients of any one of the variables be opposites so that we can put the equations together and eliminate that variable.
To solve a simultaneous equation by using the elimination method, you eliminate any one variable first.
Before you can do that, the coefficient of one of the variables in the two equations must be the same.
From the given questions, for the coefficient of one variable in the two equations to be the same, we multiply the first equation by 3.
If we can do this, the coefficient of Y in the two equations will now be 3.

(3x-5) + (x+10) + (x) =180⁰
5x+5= 180
(subtracting 5 from both sides)
5x=180-5
5x= 175
(dividing by 5)
x= 35⁰
so the angles of the triangle are

A bar over a digit in a decimal number, such as 0.133 with a bar over the 3, indicates that the number is a repeating decimal. In this case, 0.133 is a repeating decimal and the digit 3 is repeating infinitely.
What is repeating decimal?A repeating decimal is a decimal number whose digits are periodic and repeat infinitely. They are also called recurring decimals. For example, 0.333... is a repeating decimal, with the digit 3 repeating indefinitely. The same goes for 0.666... and so on. They can also be represented in the form of a fraction, where the numerator is the repeating decimal and the denominator is a power of 10 with a 1 followed by as many zeroes as the number of digits in the repeating block. Repeating decimals can also be represented with a bar over the repeating block of digits, for example 0.133 with a bar over the 3, indicating that the digit 3 is repeating infinitely. It's also written as 0.133(3) where (3) means the repeating decimal. Another way is to use a dot above the repeating digit.To learn more about decimal refer:

How do you find the coordinates of a point example?
Answers
To find the coordinates of a point in a coordinate system, do the inverse. Start at the point and trace a vertical line up or down to the x-axis. There you have your x-coordinate. Then repeat the process, but this time follow a horizontal line to determine the y-coordinate.
A point is identified by its ordered pair of (x, y). The first number represents the x-coordinate, while the second represents the y-coordinate.
To graph a point, you draw a dot at the coordinates of the ordered pair. It's usually a good idea to begin at the beginning.
An ordered pair of integers, such as an x-coordinate, which is a number on the x-axis, and a y-coordinate, which is a number on the y-axis, can be used to identify each point. Parentheses are used to indicate ordered pairings (x-coordinate, y-coordinate). The starting point is at (0,0).

$45 per month
$25 per GB over the amount of 10
Need to find out:
How much would Kadeesha have to pay in a month where she used 4 GB over the limit, how much would it be if it went over xx GB?
Let's solve the first problem:
10 GB included + 4 GB (over) =14 total GB
$45=10GB. $25×4= 4 GB over.
$45+$100=$145
Therefore, Kadeesha would have to pay $145 if she went 4 GB over the 10.
Now, let's solve the next problem:
So, for this problem we are going to find the amount it wil be in other various amounts. To do this we will create a chart /table
$45 ------> 10GB
$70 -----> 11 GB
$95 ----> 12 GB
$120 ---> 13 GB
$145 ---> 14 GB
$170 ---> 15 GB

The equation can be solved by adding 3 to both sides of the equation.
Solve the equation t − 3 = 17 for t?To solve the equation t − 3 = 17, we need to add 3 to both sides of the equation. Doing so, we get t = 17 + 3 = 20. Therefore, the value of t is 20.In this case, the variable is t. The equation t - 3 = 17 has 3 subtracted from t on the left side, so to isolate t, we must add 3 to both sides to make the equation equal. Once we do this, we are left with t = 20.The equation t − 3 = 17 is an equation with a single variable, t.The equation t - 3 = 17 is a simple algebraic equation that can be solved by performing the inverse operation of subtraction. To solve this equation, we must first add 3 to both sides of the equation.Therefore, the solution to the equation t - 3 = 17 is t = 20.The equation can be solved by adding 3 to both sides of the equation. When 3 is added to the left side of the equation, it cancels out the -3, leaving just t. When 3 is added to the right side of the equation, it increases the value of the right side from 17 to 20. Therefore, the equation t − 3 = 17 can be solved by adding 3 to both sides, which results in the equation t = 20.This means that the value of t is 20.To learn more about the value of the unknown variable refer to:

What is the value of y (angles)
Answers
Answer:
39°
Step-by-step explanation:
At the section the angles are connected, meaning that the angle across from w is the same as w and same applied to x. To find y, you first need to find w, to find the 2nd angle of the triangle of the right.
To do this, you need to add up 42 + 85.
(All triangles angles = 180)
42+85=127
subtract this from 180 to find angle w
180 - 127 = 53
53 = Angle w, which is the same as the angle across from angle w (second angle).
Second, take 53 + 88 = 141
Subtract this from 180
180-141 = 39.
39 is y°
