I don't inform my personal information to anyone
To solve this we need to figure out what 7.5% of 15,500 is. (It’s 1162.5). Now we know that after one year it is a total of 16,662.5. We then figure out what 7.5% of 16,662.5 is, which is 1,249.6875. You then add that to 16,662.5 which comes out to 17,912.1875. We then figure out 7.5% of that is 1,343.4140625. We then add that to the last total which is 19,255.6015625 and we simplify that to 19,256 and we find out that the final total is $19,256. But it wants how much have we earned which means we need to subtract the original from the new, which is 3756 and we add a unit.
Meaning the final answer is $3,756.
45,000 would be her new salary.
25,000 × .8 = 20,000.
20,000 + 25,000 = $45,0000.
The area for a trapezoid is A = 1/2 h (base 1 + base 2). You have the top base of 8. But straight down underneath that is also a base of 8. Next to that 8 you have a 4, so thus far you have a bottom base of 8 + 4. But you're missing what's over on the left. That base measure of that triangle is also 4, because the triangles are congruent. So the whole bottom base is 4 + 8 + 4 = 16. Now you have everything you need: A = 1/2 (6) (8 + 16). Do the addition inside the parenthesis first to get 24. Now multiply that by 6 to get 144. Now finally, divide that by 2 to get 72 cm^2
