Answer:
640.0
Step-by-step explanation:
To solve this problem you have to set up a proportion. To form one side of the proportion you use "is over of" meaning what number represented by is, in this case 18, is placed over the number represented by of, 3000.

Since you are finding the percent of something, youre x value is placed above "100" because percent values are most commonly out of 100%.
So now your proportion will look like


To solve the proportion you cross multiply and divide. So you multiply 100 and 18 since they are crossed from each other, then divide 1800 by 3000. The answer is .6. 18 is .6% of 3000.
Answer:
Step-by-step explanation:
Using the formula
Initial -final/initial =%/100
89-72/89 =%/100
17/89 =%/100
Making %subject of the formula
% =17*100/89
So % =1700/89
%= 19.101
Therefore rounding off the answer we have
X=19%
Answer:
I suppose you mean 999^2
(1000-1)^2
which comes under the identity
(a-b)^2=
(a^2 + b^2 - 2ab)
hope this helps
Answer:
By rounding to nearest tenth which would be the 3.16 which is closer to 3 than 3.25
