The formula for circumference is
your radius is 4mm so
which equals to
(b) type
in your calculator and round it off to the nearest hundred
this should be the answer: 25.133 mm
The answer is 6.666 repeating because there are 20 ounces overall you would divide by three to get your answer the formula would be 20÷3=6.6

8.4 x 10^10 in scientifif notation is the same, in regular its 84000000000
3 x 10^7 in scientific notation is the same and in regular its 30000000
Answer: x=30
Step-by-step explanation:
The sum of the angles must be 360.
4x+3x+3x+2x = 12x
12x = 360
x =360/12 = 30
Exercise 4
A grow from 13.1 millions to 14.4 millions means to grow
millions. So, the question is: which percentage of 13.1 is 1.3? Well, we have to find a number x such that
Solving for x, you have
Exercise 5
27% is a bit more than 25%, which is a quarter. So, we expect to find a pie chart with one slice occupying roughly one quarter of the pie. The example that best suits this requirement is B (A is almost half, and C is less than one quarter).
