Answer:
The question after change the mixed number to improper & using KCF will become :
Option B is correct option.
Step-by-step explanation:
We need to change the mixed number to improper & use KCF to rewrite the question.
The expression is:
First converting mixed fraction into improper fraction
Multiply whole number with the denominator i,e (3*2=6) now add the numerator i.e (6+1) = 7/2
Solving:
Using KCF
KCF stands fro Keep it, Change it, Flip it.
It is used when division sign is converted to multiplication the term (1/3) is reversed to (3/1)
So, our expression will be
So, The question after change the mixed number to improper & using KCF will become :
Option B is correct option.
Answer:
Step-by-step explanation:
The circumference of the outside of a ring is 66 mm and it has an outer diameter of 21 mm. The difference between the outer diameter and the inner diameter of the ring is its thickness. The thickness is constant around the ring. This means that inner outer and circles of the ring are similar. Therefore
Ratio of the outer diameter of the ring to the outer circumference of the ring = ratio of the inner diameter of the ring to the inner circumference of the ring. Therefore
21/66 = inner diameter/50
66× inner diameter = 50 × 21
Inner diameter = 1050/66 = 15.91mm

6 x 106 = 636
3 x 105 = 315
315 x (2) = about 630
-20%
Basically, we are trying to find the change from 30 to 24 in terms of percent. We do this in three steps:
1) Find the difference between 30 and 24 as a number.
2) Divide the result from Step 1 by the starting number 30.
3) Multiply the result from Step 2 by 100 to get it in terms of percent.
The three steps above can be made into a formula. Thus, to find the percent change from 30 to 24, we use this formula:
((Y-X)/X)*100 = Percent Change
X is the starting number 30, and Y is the ending number 24 that it changed to. When we enter these numbers into the formula, we get:
((24-30)/30)*100 = -20.00%
Thus, the answer to the question "What is the Percent Change from 30 to 24?" is:
-20.00%
Answer:
Step-by-step explanation:
An equation is 5p + 2 = 18.5.
The 1950 population was approximately 3.3 million.
Step-by-step explanation:
If p million was the population in 1950 the equation is:
5p + 2 = 18.5
5p = 16.5
p = 16.5 / 5
p = 3.3 million.
