Divide $55.65 by 7 to get the cost of 1 key chain ($7.95). Then multiply the cost of 1 by 12 and get $95.40
Answer: She could have the same future value and invest less than $2,000 initially if she could earn more than 64.5 percent interest.
Step-by-step explanation:
This is something you would do through trial and error. At least, that's the approach I took. I'm not sure if there is any algorithm to solve. The solution I got is shown in the attached image below. There are probably other solutions possible. The trick is to keep each number separate but not too far away so that the other numbers to be filled in later don't get too crowded to their neighbor.
Side note: any mirror copy of what I posted would work as well since you can flip the page around and it's effectively the same solution.
Answer:
1. We already have the measure of the hypotenuse and one out of two acute angle, therefore:
sin53° = x/45 => x = sin53° · 45 ≈35.94
2. We already have one out of two legs of the triangle and one acute angle so we know that:
tan27° = 48/x => x = 48/tan27° ≈ 94.21
Answer:
1.33
Step-by-step explanation:
7.98 divided by 6 = 1.33
6 goes into 7 once then 7-6= 1 bring down the 9. 6 goes in 19 3 times 19-18=1 bring the 8 down then 6 goes into 18 3 times.
