0.83
Step-by-step explanation:
The $500 price increase over this 12 year span results in the inflation rate:
$500
---------- = 0.83..., or 0.83 to the nearest hundredth (equivalent to 83%)
$600
1, 5, 4, 2, 3 in that order
Answer:
Make sure you are using a perfect circle. This method won't work with ellipses, ovals or anything but a real circle. A circle is defined as all the points on a plane that are an equal distance from a single center point. The lids of jars are good household objects to use for this exercise.You should be able to calculate pi roughly because in order to get exact results of pi, you will need to ...
Measure the circumference of a circle as accurately as you can. The circumference is the length that goes around the entire edge of the circle. Since the circumference is round, it can be difficult to measure (that's why pi is so important). Lay a string over the circle as closely as you can. Mark the string off where it circles back around, and then measure the string length with a ruler.
Measure the diameter of the circle. The diameter runs from one side of the circle to the other through the circle's center point.
Use the formula. The circumference of a circle is found with the formula C= π*d = 2*π*r. Thus pi equals a circle's circumference divided by its diameter. Plug your numbers into a calculator: the result should be roughly 3.14.[3] X Research source
Repeat this process with several different circles, and then average the results.
Step-by-step explanation:
Answer:
1.A. 88.89
2.B.6.3%
3.C.64.92%
Step-by-step explanation:
1.
to covert it into percentage multiply it with 100
then it becomes 88.888
rounding off to the nearest hundred it becomes 88.89
2. to convert into percentage multiply it with 100
therefore 0.063×100=6.3%
3. to find percentage
%= (no of students using mobile / total no of students )× 100
= 
×100
=64.918
Rounding off to nearest hundred it becomes 64.92%
