Step-by-step explanation:
2 : 3 = 6 : x ,
Ratio can be written as
2*3 = 6, we multiply top and bottom of fraction by 3
So value of x=9
4 : 7 = x : 42 ,
7*6 = 42, we multiply top and bottom of fraction by 6
So value of x=24
2x : 48 = 3 : 12,
\frac{3}{12}[/tex] =
2x= 12, so x= 6
12 : 15 = x : 20
,
we multiply top and bottom by 4/3

So value of x=16
It's 150.8

Before we begin, let's cross out "the small wheel could have an 18 inch diameter". This is useless information and should be disregarded to avoid confusion. Lots of questions include extraneous information to make you second guess yourself, so it is important to be aware of what the question is asking you and what you need in order to answer it.
The formula for circumference is

x diameter. With this formula, we can substitute the value of the diameter, 52, into the equation.
Circumference = 3.14 x 52
Circumference = 163.28
Final Answer: the circumference of the big wheel is 163.28 inches

The coordinates would be (3, 3).
The slope from R to S is given by
m = (0 - 0)/(-4-1) = 0/-5 = 0
The distance from R to S is 5 units straight across.
This means the slope from T to U will be 0, and it will be a horizontal segment. This means the y-coordinate of U will be 3, since the y-coordinate of T is 3.
The distance from T to U will be 5 as well; -2+5 = 3 for the x-coordinate.
This makes the point (3, 3).
