Lets use 1 to solve this problem because it is easiest to show.
Multiply 1 by 1.3 for a 30% increase (1*1.3=1.3).
Then multiply 1.3 by .7 for a 30% decrease. (1.3*.7=.91)
Therefore the page had a 9% reduction from its original size or is 91% of its original size.
Answer:
76.54 ft
Step-by-step explanation:
Pythagorean theorem
37^2 + 67^2 = d^2
d = 76.54 ft
I believe the answer is 644=200+12a
Answer:
39.43 for each dog
Step-by-step explanation:
<u>d = 2c (given) </u>
164 c + 23 d = 4140 sub in the above equation for d
164 c + 23<u> (2c)</u> = 4140
210c = 4140
c =19.71
d = 2c = 39.43
The simplest I can put it
10^1 = 10
10^2 = 100
10^3 = 1000
(essentially the number of zeroes)
5*10^2 = 5*100 = 500 (adding 2 zeroes, or moving the decimal over 2 places
Same works for numbers smaller than zero
5*10^-2 = 5*.01 = .05 (moving the decimal to the right 2 places
