A flagpole has a height of 10 yards. It will be supported by 3 cables, each of which is attached to the flagpole at a point 4 ya rds below the top of the pole and attached to the ground at a point that is 8 yards from the base of the pole. Find the total number of yards of cable that will be required.
1 answer:
Pytagorean theorem height10 attached at 10-4=6 yards from bottom 8 yards from base to away a^2+b^2=c^2 a and b are side legnths and c=hypotonuse so therfore we are given a and b and we must solve for c so 6=height 8=base 6^2+8^2=c^2 36+64=c^2 100=c^2 square root 10=c so therfor the legnth of each cable is 10 yards 3 cables so 3 times 10=30 30 yards needed

Answer:
$80
Step-by-step explanation:
First you take 500 and multiply by 16% or .16.
You should get 80.
A tip for the future is when you have a percentage just move the decimal place to the left twice.
ie. 50%=.50, 125%=1.25, 2%=.02
