Answer:

Step-by-step explanation:
Let x be the percentage then...

Start by dividing both sides by 4:

Simplify the fraction:

Then, multiply the fraction by 50/50, so we can get a number over 100 (that number would be the percentage). Note we can only multiply it by 50/50 since it is essentially multiplying the fraction by 1.

1. a)CK²=CH²+HK², CH - radius
CH²=CK²-HK²=50²-30²=2500-900=1600 ft²
CH=40 ft -- radius
b) cos(KCH)= CH/CK=40/50=4/5
KCH=arccos(4/5)≈36.87°
2)C=2πr≈2*3.14*40=251.2 ft
C=2*40π=80π ft --- exact
3) A =πr²=40²π=1600π ----exact
A≈1600*3.14=5024 ft
The answer is 18.
If you multiple 3 x 3 x 2 you get 18 different ways to arrange the books
258/300 u have to simplify 300 and 258 r both divisible by 3, 258/300 divided by 3/3 equals 86/100, as a decimal this is 0.86 and as a percent is is 86%
