Answer: 98.1%
Explanation:
A 10% sale means that the post-sale price of the item is now 90%, or 0.9 of the original cost of the item. We then apply 9% sales tax by multiplying the 0.9 by 109%, or 1.09. 0.9 * 1.09 = .981, so the total cost of the item is 98.1% of the original pre-sale sticker price.
For percentage problems that do not deal with a specific starting number, it is always helpful to plug in 100 for the starting number. Here, we would then have a post-sale price of 90 dollars, and if we calculate the sales tax for the 90-dollar item it would be 90 * 0.09 = $8.10. THis gives us a total cost of 90 + 8.10 = $98.10, or 98.1% of the original 100-dollar price.

Answer:
She messed up the equation, A= B x h, she changed it midway, and also, you need to add the one half to make the equation valid
Step-by-step explanation:
A=1/2 x b xh
17.5 = 1/2 x 5 x h
35=5h (multiply both sides by 2 to get rid of one half)
35/5 = 5h/5
7=h
The height of the triangle is 7 units
