Answer:
ist the question
Step-by-step explanation:
write question first
To find a percentage of a number we multiply the percentage times the number and get the result, here we have the percentage and the result and need to find out which number it corresponds to, lets write an equation to do so and keep in mind that the percentage itself can be written in a different way:
225% = 225 out of 100 = 225/100
So we have this equation, where we call x the number we are looking for:
<span>(225%)(x) = 81
</span>(225/100)(x) = 81
so we solve for x:
225x = 81*100 = 8100
x = 8100/225
x = 36
The original number is 36, hence 225% of 36 is 81
Step-by-step explanation:
here,,
a=3,b=10,C=120°
c^2=a^2+b^2-2ab cos120°
=(3)^2 +(10)^2 _2 (3)(10)(-1/2) [cos120°=-1/2]
=9+100-(-30)
=109+30
=139
c=(139 )1/2=11.79
c=12
Answer:
D) six hundred twenty-nine thousandths > six times one tenth plus three times one hundredth plus two times one thousandth
629000>8403 TRUE
Step-by-step explanation:
A) six times one tenth plus three times one hundredth plus two times one thousandth < six hundred twenty-nine thousandths
8,403.00
<629000 FALSE
B) six times one tenth plus three times one hundredth plus two times one thousandth = six hundred twenty-nine thousandths
8403= 629000 FALSE
C) six hundred twenty-nine thousandths < six times one tenth plus three times one hundredth plus two times one thousandth
629000<8403 FALSE
D) six hundred twenty-nine thousandths > six times one tenth plus three times one hundredth plus two times one thousandth
629000>8403 TRUE

Answer:
100%
Step-by-step explanation:
An exponential equation with a growth rate can be expressed as: 
where r is a positive number, and represents the growth rate.
In this case since the base of the exponent equals 2, that means r=1, since 1+1=2. This means it has a growth rate of 100%, which makes sense, since the base is 2, meaning it doubles or increases by 100% every time x increases by 1.
