Which set represents a Pythagorean triple?

D: 68. 72.81
Answer:
Step-by-step explanation:
B
The set that represents a Pythagorean triple is B: 33, 44, 55
What is a Pythagorean triple ?A Pythagorean triple consists of three positive integers such that the square of the larger one of them is equal to the sum of the squares of the other two .
Let (a, b, c) represents a Pythagorean triple where a, b, c are positive integer and a is the larger one then a² = b² + c²
For A: 27 ,38, 42
Let a = 42 , b= 38 ,c= 27
⇒a² = 42² = 1764
and b² + c² = 38² + 27² = 1444 + 729 = 2173
∴a² ≠ b² + c²
Thus , A: 27 ,38, 42 is not a Pythagorean triple
For B: 33 ,44, 55
Let a = 55 , b= 33 ,c= 44
⇒a² = 55² = 3025
and b² + c² = 33² + 44² = 1089 + 1936 = 3025
∴a² = b² + c²
Thus , B: 33 ,44, 55 is a Pythagorean triple
For C: 35 ,38, 42
Let a = 42 , b= 35 , c= 38
⇒a² = 42² = 1764
and b² + c² = 35² + 38² = 1225 + 1444 = 2669
∴a² ≠ b² + c²
Thus , C: 35 ,38, 42 is not a Pythagorean triple
For D: 68 ,72, 81
Let a = 81 , b= 68 , c= 72
⇒a² = 81² = 6561
and b² + c² = 68² + 72² = 4624 + 5184 = 9808
∴a² ≠ b² + c²
Thus , D: 68 ,72, 81 is not a Pythagorean triple
Therefore, Only set B: 33, 44, 55 represents a Pythagorean triple.

According to the table, what is omar’s bank balance? $761.25 $810.30 $814.75 $1,186.25
The total remaining bank balance in the account of Omar after reducing all the debit and adding paycheck is $761.25
What do you mean by debit and credit amount?The money which is paid from an account is called the debit amount and the money which is paid into an account is called the credit amount.
To know the remaining balance of account, all the debit amount is subtracted from it and all the credit amount is added into it.
The table for the Omar's transaction is attached below. The data given in the table is,

Thus, the total balance in his account without any debit is,
[tex]A_i=1015.50+219.80\\A_i=1253.30[/tex]
The total amount debited from the account of Omar is,

A heptagon has angles that measure 120°, 110°, 140°, 135°, 160°, 100°, and b. What is b?
Answer:
Here,
We know that,
Sum of interior angles of a heptagon=900°
So,
b+120+110+140+135+160+100=900
or, b+765= 900
or, b=900-765
Therefore, b= 135°

Joseph and his family were going to the beach. Joseph's sister was running late so Joseph left their house with his mom. Joseph's dad waited for his sister to get ready and left one hour later driving 75 km/hour in an effort to catch up to Joseph and mom. After
driving for four hours Joseph's dad finally caught up. How fast was Joseph's mom driving?
Select the correct response:
100 km/hour
30 km/hour
60 km/hour
50 km/hour
Answer:
60 km/hr.
Step-by-step explanation:
When Dad caught up the the time he had been driving was 4 hours and the time Mom had been driving was 1 + 4 = 5 hours.
They both drove the same distance, d km.
For Dad:
speed = d / time
75 = d / 4
d = 75 * 4 = 300 km.
Mom took 5 hours to travel this distance, so
Mom's speed was 300 / 5 = 60 km/hr.

Answer:
C. a rotation 180° clockwise about the origin followed by a reflection across the line y = x
Step-by-step explanation:
Let us assume that the coordinate of A in triangle ABC is A(x, y)
A) If there is a reflection across line y = x, the new coordinate is at A'(y, x).
If a reflection across the line y = -x is then followed, the new coordinate is at A"(-x, -y)

A karate school offers a package of 12 group lessons and 2 private lessons for $110. It also offers a package of 10 group lessons and 3 private lessons for $125. Write and solve a system of equations to find the cost of a single group lesson and a single private lesson.
Answer: The cost of a single group lesson is $5 and a single private lesson is $25
Step-by-step explanation:
Let the cost of a single group lesson be y.
Let the cost of a single private lesson be z.
A karate school offers a package of 12 group lessons and 2 private lessons for $110. This can be written as:
12y + 2z = 110 ..... equation i
It also offers a package of 10 group lessons and 3 private lessons for $125. This can be written as:
10y + 3z = 125 ...... equation ii
Combining equation i and ii
12y + 2z = 110 ..... equation i
10y + 3z = 125 ...... equation ii
12y + 2z = 110 × (3)
10y + 3z = 125 × (2)
36y + 6z = 330 ....... equation iii
20y + 6z = 250 ...... equation iv
Subtract equation iv from iii
16y = 80
y = 80/16
y = 5
From equation ii
10y + 3z = 125
10(5) + 3z = 125
50 + 3z = 125
3z = 125 - 50
3z = 75
z = 75/3
z = 25
The cost of a single group lesson is $5 and a single private lesson is $25
A group lesson costs = $5.
A private lesson costs = $25.
Let a group lesson costs = $x
A private lesson costs = $y.
According to the question:
12x + 2y = 110
10x + 3y = 125
Solving them we get x = 5, y = 25

If the height of an object at time t can be represented by
h(t) = -16t2 + 38t + 9, find h(7).
Answer:
-509
Step-by-step explanation:
h(t) = -16t² + 38t + 9
h(7) = - 16(49) + 38(7) + 9
h(7) = -784 + 266 + 9
h(7) = -509
Solution:
It should be noted:
Given equation: h(t) = -16t² + 38t + 9To find h(7), let's find "t" by comparing h(7) and h(t).
Compare h(7) and h(t):
h(7) = h(t)=> h(7)/h = h(t)/h=> 7 = tNow, find h(7) by substituting the value of t into the equation.
Substitute the value of t into the equation:
h(t) = -16t² + 38t + 9=> h(t) = (-16)(t²) + (38)(t) + 9=> h(7) = (-16)(7²) + (38)(7) + 9=> h(7) = -784 + 266 + 9=> h(7) = -509Thus, h(7) is -509.
solve for x: |3x+12|= 18
=====================================================
Work Shown:
|3x+12| = 18
3x+12 = 18 or 3x+12 = -18
3x = 18-12 or 3x = -18-12
3x = 6 or 3x = -30
x = 6/3 or x = -30/3
x = 2 or x = -10
The rule used in step 2 is the idea that if |x| = k, for some positive number k, then x = k or x = -k. One equation breaks into two separate ones. From there we solve each equation for x as normal. Follow PEMDAS in reverse, undoing each operation, to isolate x.
If you're curious why the absolute value breaks into two parts, consider something like |x| = 7. This means x is 7 units away from zero on a number line. There are two possible locations where x could be: 7 and -7. This is one example showing why we get two different results. The same applies to our equation as well, just it's a bit more complicated.
2x + 5 = 13
what is x
Answer:
x = 4
Step-by-step explanation:
it's important to keep in mind that you can do anything to an equation as long as you do it to both sides, and it will still be equal.
2x + 5 = 13
subtract 5 from both sides of the equation
2x + 5 -5 = 13 - 5
2x = 13 -5
2x = 8
divide both sides of the equation by 2
2x/2 = 8/2
x = 4
The value of x for the equation 2x + 5 = 13 is x = 4.
Given that:
There is an equation in x which is given as,
2x + 5 = 13
It is required to find the value of x.
That is, solve the equation.
It is required to get the equation in such a way that x is on one side and a constant on the other side.
2x + 5 = 13
Subtract both sides by 5.
2x = 8
Divide both sides by 2.
x = 4
Hence the value of x is 4.

paid $123. Curly bought two CDs and four DVDs and paid $84. What is the
cost of one CD? What is the cost of one DVD?
(Can y’all help me out real quick please)
How do I write my two equations for this??
Answer: one CD cost $12 and one DVD cost $15 .
Step-by-step explanation:
In this situation we will represent the cost o one CD by x and the number of one DVD by y. Four CDs plus five DVDs cost 123 so we will represent it by the equation 4x + 5y = 123
The same or the second part of the statement. 2 CDs plus 4 DVDs cost $84 so we will also represent that by the equation , 2x + 4y = 84
Since we have two equations we will use it to solve or x and y using the elimination method.
4x + 5y = 123
2x + 4y = 84 Multiply the down equation by -2 to eliminate the x variable.
-2(2x + 4y ) = -2(84)
-4x -8y = -168
We will now have the new equations ,
4x + 5y = 123
-4x - 8y = -168 Add both equations to
-3y = -45
y= 15
This means each DVD cost $15 .
Now we will now have to solve for x by plotting in the value of y into the equation .
4x + 5(15) = 123
4x + 75 = 123
-75 -75
4x = 48
x = 12
This also means that one CD cost $12.
