100 points my grades depend on this

She earned 1149, which is between 436 and 1506 so you would use the 2nd row for the information.

the tax rate says 15% for the amount over 436
 so fist find the amount that is taxable:

1149 - 436 = 713
 now multiply that amount by 0.15 ( 15% as a decimal)

713 * 0.15 = 106.95

now add the base tax to that amount for the total amount of tax:  
106.95 + 34.90 = 141.85 total tax withheld

AC = 16 in.

Step-by-step explanation:

AD = CD = 10 in.

BD = 6 in.

AC = 2(AB) = ?

Apply pythagorean theorem to find AB

AB² = AD² - BD²

Substitute

AB² = 10² - 6²

AB² = 64

AB = √64

AB = 8

Therefore:

AC = 2(AB) = 2(8)

AC = 16 in.
