Answer:
6.6% = tax rate
Step-by-step explanation:
The first step is to find out how much was paid in tax
24.91 - 23.37 =1.54
The tax is 1.54
The tax is the original price * tax rate
1.54 = 23.37 * tax rate
Divide each side by 23.37
1.54/23.37 = tax rate
.065896448= tax rate
Changing to percent form
6.6% = tax rate

Answer:
a lot
Step-by-step explanation:
a^2+b^2=c^2
where c=25 m. and a=2b-10 m.
substitute
(2b-10)^2+b^2=25^2
4b^2-40b+100+b^2=625
5b^2-40b+100=625
divide both sides by 5
b^2-8b+20=125
subtract 20 from both sides
b^2-8b=105
complete the square
take half of 8 and square it=16
