In 6 weeks.



For this problem, you need to determine the least common multiple of the numbers given which is 2, 3, and 6. You can calculate the LCM of multiple numbers by pairs.



The LCM of 2 and 3 is 6 because 6 is the smallest possible number that can be evenly divided by both 2 and 3.



Now you need the LCM of 6 and 6. Which is also 6, because 6 is the smallest number that can be evenly divided by 6.



So the LCM of 2, 3, and 6 is 6. So in 6 weeks, Clea will once again have a music less, attend dance class, and have a dental appointment, all during the same week.

The area of a circle is 9π in². What is the circumference, in inches? Express your answer in terms of \piπ
dangina [55]

Answer:

6\pi in

Step-by-step explanation:

The formula to find the area of a circle: \pi r^{2}, where r is the radius.

The formula to find the circumference (perimeter) of a circle: 2\pi r, where r is the radius.

1) To find the circumference of the circle, we need to find the radius (r) first. Since the area of the circle is given to us, we need to equate this to the formula to find the area of a circle.

9\pi =\pi r^2

Cancel the \pi by bringing it to the other side.

9 =\pi r^2 ÷ \pi

9 = r^2\\\sqrt{9} = r\\3 = r

2) Find the circumference of the circle by using the formula, 2\pi r.

=  2*\pi *3

= 6\pi in

Can you do this problem and show work
tresset_1 [31]
Just in case you didn’t know, you can also use photomath, for math problems. They give you the answer and they also include the steps. You can do that instead of waiting for someone to answer here, it’ll be alot faster:)

0.5x+4.2=5.9
subtract 4.2 from the left and right sides 
then divide on the left and right sides

Use the confidence level and Sample data to find the margin of error E. Round your answer to the same number of decimal places a
Ivenika [448]

Answer:

A) 2.6 mm Hg

Step-by-step explanation:

Margin of error = critical value × standard error

ME = CV × SE

n > 30, so we can approximate CV with a normal distribution.  At P = 94%, CV = 1.88.

SE = σ / √n

SE = 13.5 / √92

SE = 1.41

So the margin of error is:

ME = 1.88 × 1.41

ME = 2.6
