Answer:
I assume AC = 49.89 since the number is cut off
Step-by-step explanation:
tangent(degree) = opposite / adjacent
To find AC, you can set up tan(29) = AC / CB
tan(29) = AC / 90 (the picture is cutted off, so I assume....)
= AC
Answer:
6
Step-by-step explanation:
First we need to find what 3% of 700 is. We know 10% is 70, 5% is 35, so we need to find out what 3% is. If you don't know how to calculate percentages of a number, I recommend starting with 10%. This way you know 10% of the number is 70, so you will also know that 1% of the number is 7. 7 x 3 = 21. So 3% of 700 is 21. Since it was over 6 years, we multiply 21 x 6. That gives us 126. She will be paid $126 in interest in the first six years.
25% 6 divided by 24 will give you the percentage of copper in the bar
