Answer: C
Step-by-step explanation:
Since there are 12 inches in 1 foot,
42 feet converts to 42 x 12 = 504 inches. If he makes a cut starting on one side, he will make 504/20 = 25.2 cuts. Since he won't make a partial cut, the answer is 25
Basically all you have to do is 5,000 x 5% = 250 Hope this helps.
Assuming that you mean the FIFTH power then
7^5=7*7*7*7*7=16,807
Since we know that ratio of AB : AC is 1 : √2, then we can more or less use those values for the sides, check the picture below.
so we're really looking for tan(2A). Let's bear in mind that tan²(θ) is just another way to write [ tan(θ) ]².
