Answer: the integers that is a Pythagorean triple and are the side lengths of a right triangle is
C. 9, 40, 41
Step-by-step explanation:
A Pythagorean triple is a set of three numbers which satisfy the Pythagoras theorem. The Pythagoras theorem is expressed as
Hypotenuse^2 = opposite side^2 + adjacent side^2
Let us try each set of numbers.
A. 20,23,28
28^2 = 20^ + 23^2
784 = 400 + 529 = 929
Since both sides of the equation are not equal, the set of numbers is not a Pythagoras triple.
B. 18, 26, 44
44^2 = 18^ + 26^2
1936 = 324 + 676 = 1000
Since both sides of the equation are not equal, the set of numbers is not a Pythagoras triple.
C. 9, 40, 41
41^2 = 9^ + 40^2
1681 = 81 + 1600 = 1681
Since both sides of the equation are equal, the set of numbers is a Pythagoras triple.
D. 8, 20, 32
32^2 = 20^ + 8^2
1024 = 400 + 64 = 464
Since both sides of the equation are not equal, the set of numbers is not a Pythagoras triple.
Sales tax = 5%
Sales Tax = $2
⇒ 5% is equal to $2
------------------------------------------------------------
Find 1%:
------------------------------------------------------------
5% = $2
1% = $2 ÷ 5
1% = $0.40
------------------------------------------------------------
Find 100% (Cost of the meal):
------------------------------------------------------------
100% = $0.40 x 100
100% = $40
------------------------------------------------------------
Find tips:
------------------------------------------------------------
15% tips = 15% x $40
15% tips = 0.15 x 40
15% tips = $6
------------------------------------------------------------
Find total cost:
------------------------------------------------------------
Total cost = $40 + $2 + $6 = $48
------------------------------------------------------------
Answer: $48
