10. Which of the following sets of numbers represents a Pythagorean
Triple?
A {10, 5, 12}
B {2,4,5)
C {1,2,3}
D {14, 48, 50 }
Answer:
D
Step-by-step explanation:
Trust me I used a calculator and and different one to make sure my answer was correct.
{14, 48, 50} represents a Pythagorean Triple, hence option (D) is correct.
If three sides of any triangle are a, b and c and c is the largest one then the condition that a, b and c will form a Pythagorean triplet is as:
c² = a² + b² -----(1)
An option which will satisfy the condition (1) will form a Pythagorean Triple.
Let's check for all the given options:
A) {10,5,12}
Since, 12 is the largest number out of three.
Therefore, c = 12, a = 5, b = 10
Now,
a² + b² = 5²+10²
a² + b² = 25+100
a² + b² = 125
a² + b²≠ 15²
a² + b²≠ c²
Hence, {10, 5, 12} will not form a Pythagorean Triple. Option (A) is incorrect.
B) {2,4,5)
c = 5, a = 2, b =4
a² + b² = 2²+4²
a² + b² = 4+16
a² + b² = 20
a² + b² ≠ 5²
Hence, option (B) is also incorrect.
(C) {1,2,3}
c = 3, a = 1, b = 2
a² + b² = 1²+2²
a² + b² = 1+4
a² + b²= 5
a² + b² ≠ c²
This is also not forming a Pythagorean Triple, that is why incorrect.
(D) {14, 48, 50}
c = 50, a = 14, b = 48
a² + b² = (14)²+(48)²
a² + b² = 196 +2304
a² + b² = 2500
a² + b² = (50)²
a² + b² = c²
This satisfies the condition (1) hence, it is forming a Pythagorean Triple.
This option is an appropriate choice.
Hence, option (D) is correct, that means {14, 48, 50} represents a Pythagorean Triple.

For this, "x" is a multiplication symbol
Option 1: 35x1.09=38.15 (the 1.09 is how u calculate tax btw)
then 38.15-35=3.15
OR
A simpler way:
Option 2: 35x9% (or 35x.09) however u want to put it)

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold. Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.
Answer:y = -2/3x + 490
Step-by-step explanation:
2x +3y = 1470
Slope intercept form definition: y = mx + b is the slope-intercept form of a line where m is the slope and b is the y-intercept.
2x + 3y = 1470
2x + 3y -2x = 1470 - 2x - Subtract 2x from both sides
3y = 1470 - 2x - Simplify
3y/3 = 1470/3 - 2x/3 - Divide both sides by 3
y = -2/3x + 490 - Simplify
-⅔ is the slope and 490 is the y-intercept

The point J(-2, 3) is rotated 90° clockwise around the origin. What are the coordinates of the resulting point, J′?
Answer:
J' (3, 2)
Step-by-step explanation:
when a point is rotated 90 degrees clockwise, the point goes from (x, y) to (y, -x). You can imagine this rule or come up with it by doing a rotation on a graph, but really it's just a rule you should memorize.
So, apply (x, y) --> (y, -x) to this point:
(-2, 3) --> (3, 2)

Ahmed is riding the elevator in a building. The building has floors above and below ground level. Ahmed uses the expression below to describe his movement.
Answer:
Step-by-step explanation:
The question is incomplete. Here is the complete question
Ahmed is riding the elevator in a building. The building has floors above and below ground level. Ahmed uses the expression below to describe his movement. 6 + (–8) Which statement could describe Ahmed’s movement?
Given the expression
6+(-8)
Let's denote upward movement in the elevator as positive and downward movement as negative.
+6 means that Ahmed rides 6 floors above in the elevator (since +be means upward movement in the elevator)
-8 means that from that 6th floor, he then moves 8 floors downwards in the elevator. In other to determine the floor Ahmed is, we can evaluate the given expression:
= 6+(-8)
Note that -×+ = -, hence the expression becomes;
= 6-8
= -8+6
= -2
This means that Ahmed is 2 floor below or down the elevator.
Answer: He moved 6 floors up, then moved 8 floors down. So he is now 2 floors below ground level.

The width of a rectangle is 3 less than twice the length, x. If the perimeter of the rectangle is 43 feet, find the dimensions.
Answer:
Step-by-step explanation:
we're given that
[tex]W = 2X - 3\\P = 43\\[/tex]
the perimeter can be defined as
[tex]P = 2X + 2W \\so\\43 = 2X + 2(2X - 3)\\43 = 2X + 4X - 6\\6X = 49\\X = \frac{49}{6}\\ W = 2X - 3\\W = 2(49/6) - 3\\W = 49/3 - 9/3 = \frac{40}{3}[/tex]
The rectangle is
[tex]\frac{49}{6} by \frac{40}{3}[/tex] feet
