Answer: y = 800
Step-by-step explanation:
3(y+200) = 3000
y+200 = 1000 (dividing 3 from both sides)
y = 800
The answer is A) because 98% of 300 is 294 and 1% of 300 is 3; first just divide 294 by 98% (.98) and u get 300 then multiply 300 by 1% (.01) and u get 3
So:
1000 meters = 1 kilometer,
So we can use the ratio 1km/1000m
Thus,
.007 kilometers*(1000m/1km) = 7 meters
So the equation is:
.007 kilometers = 7 meters
or
.007km = 7m
Answer: - 8.89%
I am going to explain you in detail ir order to help you to be able to do this kind of problems by yourself.
The definition of percent change, %, is:
change
% = ---------------- * 100
base value
The base value is from where you start or the value for which you want to asses the variation.
So, in this case the base value is 90 (starting value).
The change is final value - initial value = 82 - 90 = - 8. The negative sign means that the value decreased.
So, following the formula you get:
82 - 90 - 8
% = ----------- * 100 = -------- * 100 = - 8.89
90 90
Answer: the percent of change is - 8.89 %, meaning that the value decreased 8.89%.
