Answer:

About 1249.366

Step-by-step explanation:

After plugging the circumference into the formula c=2π*r and solving, we get about 1249.366. You can round it however necessary :)

Hope I helped!

p.s: there's calculators online that can help you convert between circumference, diameter, area, and radius! Here's a link to one that I use!

What is the value of x?
DENIUS [597]

2x+x+47

3x+47

3x+47=x+93

2x+47=93

2x=46

x=46/2

x=23

You must use all the equations that makes up the x. Using all the equations will cover the area than just using part of it.

The number of visitors to the homepage of an online magazine can be modeled by the equation y = 1100.74x − 1976.47, where x = 5
DIA [1.3K]

The number of visitors to the homepage of an online magazine in the year 2005 is 3527

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more number and variables.

Let y represent the total number of visitors x years since 2000. Hence:

y = 1100.74x - 1976.47

In the year 2005 (x = 5):

y = 1100.74(5) - 1976.47 = 3527.23

The number of visitors to the homepage of an online magazine in the year 2005 is 3527

One number is 2 less than a second number. twice the second number is 16 more than 4 times the first. find the two numbers.
Nostrana [21]
Let the numbers be x and y

x= y-2.... (1)
and, 2y = 16 + 4x.... (2)

putting the value of x from (1) in (2),

2y = 16 + 4x
=> 2y = 16 + 4(y-2)
=> 2y = 16 + 4y - 8
=> 2y = 8 + 4y
=> 2y - 4y = 8
=> -2y = 8
=> y =-8/2
=> y= -4

and x = -4-2 = -6

hence , in short the numbers are -2 and -4

Write an equation of the line below​
Kazeer [188]

Answer:

y=-1/3x+1

Step-by-step explanation:

The slope of this line is negative, and is equal to rise over run.

To find slope, count the number of spaces it has moved down or up, and then the number of spaces it has moved left or right.

The y intercept is represented by +1, and is where the line crosses the y axis.

Hope this helps!
