Hello from MrBillDoesMath!
Answer: D
In a right (angle) triangle with sides a,b, c, the Pythagorean that gives us that
a^2 + b^2 = c^2. Let go through the 4 cases presented in the problem>
A) Does 7^2 + 9^2 = 11 ^2. That is, does 49 + 81 = 121 ? Nope so these sides do not form a right triangle.
B) Does 10^2 + 15^2 = 20^2. That is, does 100 + 225 = 400 ? Nope so these sides do not form a right triangle
C) Does 12^2 + 18^2 = 22^2. That is, does 144 + 324 = 484 ? Nope, so these sides do not form a right triangle.
D) Does 8^2 + 15^2 = 17^2 ? That is, does 64 + 225 = 289. YES, so these sides can form a right triangle.
Regards, MrB.
(without tax) is $65.49.
If she is shopping in Pearland, where
the sales tax rate is 8.25%, what will
be the AMOUNT OF SALES TAX for
her dress (remember to round to two
decimal places since it's money)?
What’s the answer
Answer: Sales tax would be $5.40
Step-by-step explanation: The sales value itself of the dress (that is, without tax) is $65.49.
The amount charged as sales tax in Pearland is given as 8.25% (or 0.0825).
Hence if she is shopping in Pearland, the AMOUNT OF SALES TAX she would pay can be calculated as,
Sales tax = Sales price x 0.0825
Sales tax = 65.49 x 0.0825
Sales tax = 5.402925
Approximately to two decimal places, the sales tax becomes $5.40
