Answer:

8.48in

Step-by-step explanation:

The length of arc RS is given by:

l=\frac{\theta}{360}\times 2\pi r

From the diagram the radius is r=6.48 in and the central angle of sector RS is \theta=150\degree

We use \pi=3.14 and substitute the radius and central angle to obtain:

l=\frac{150}{360}\times 2\times3.14\times  6.48in

We simplify to get:

l=\frac{5}{12}\times 2\times 6.48in

l=\frac{5}{6}\times 3.14\times  6.48in^2

l=8.48in

Pls need help... brainliest :))
belka [17]

Answer:

I am not the best in this type of math, the best thing I can do is help you.

You see that there is a pattern in the chart? X adds 2 every column, and Y adds 4 every column.

I believe the slope simplified is 2/1, if you are following y/x. If not, then the other way around.  

Unfortunately, I can't help you with the rest of the problem, but I hope you can get a good idea of what your supposed to do.

Have a good day.

You and your family go out to dinner to build a total of $54 plan to leave 20% tip how much tip should you leave
loris [4]

Answer:

$10.8 is left.

Step-by-step explanation:

Given that,

Total amount = $54

Left amount = 20%

We need to find how much tip should you leave. It means we need to find 20% of 54. So,

A=\dfrac{20}{100}\times 54\\\\=\$10.8

So, $10.8 is left.
