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.

a swimming pool had a list price of $575.25 and was on sale for 10% off.Sara had a coupon for an extra $75 off. What will her cost be before tax?
Answer:
First take 10% off of $575.25. 10% of $575.25 is $57.53, so 10% off would be $575.25-$57.53, which makes the price $517.72. Then, including the $75 coupon, reduces the price down to $442.72. Therefore, her price before tax is $442.72.

She can cut 6.75 shorter pieces of cloth
The division operation is one of the basic arithmetic operations
Common signs used are or
The division is written by placing the numerator above the denominator with a horizontal line between them or use a slash with the numerator's position and the denominator is parallel
The division is actually an iterative subtraction operation (as many as the number of divisors)
Division is the opposite of multiplying
The general form of division can be stated by:
example:
7: 3 = 2 + 1
Division operation statement:
"7 divided by 3 equals 2 remainder 1"
The form of division can also be expressed in terms of fractions
In the example above, the form of mixed fractions is
Mixed fractions consist of whole number and proper fractions
a seamstress cuts a piece of cloth that is 3 yards long into shorter lengths of 16 inches each.
we translate this sentence into Arithmetic operations
Because One yard is equal to 36 inches,
3 yards =
3 yards =
then equation becomes :
or as mixed fraction :
