Answer:
If two angles sum is equal to 90° and makes right angle called = complementary angle...☺️✌️
Above sum solution....
one angle =x
other angle =y
According to question
x+y= 90°......(1)
x-y=22°......(2)
from one and two ....by eliminating method...
2y=68
y=68/2
y=34
put y in equation 1
x+y=90°
x+34=90°
x=90°-34
x= 56...
To verify add both
sum = 90°
Hence ..verified...

Carlos says that the XYZ is not congruent to PQR because there is no SSA theorem or postulate.
In two or more complete sentences, explain why or why not Carlos is correct. Justify your answer using triangle congruency postulates, theorems, and definitions.
Carlos is correct
Since we don't know the length of sides PR and XZ, the triangles can't be congruent by the SSS theorem or the SAS theorem, and since we don't know the measure of angles Y and Q, the triangles can't be congruent by the ASA theorem, the SAS theorem or the AAS theorem. Therefore, Carlos is correct.
Carlos is correct. Since the angles P and X are not included between PQ and RQ and XY and YZ, the SAS postulate cannot be used, since it states that the angle must be included between the sides. Unlike with ASA, where there is the AAS theorem for non-included sides, there is not SSA theorem for non-included angles, so the triangles cannot be proven to be congruent.

A restaurant starts with 10 dozen
pieces of cornbread. Every order
receives 2 piece of cornbread. At the
end of their lunch rush, there are 28
pieces of cornbread left. How many
orders did the restaurant take?
Answer:
46 orders.
Step-by-step explanation:
(10*12) - 2x = 28
120 - 2x = 28
-2x = 28 - 120
-2x = -92
x = -92/2
x = 46

➤ How to solve ?

That's quite easy but you need to recall the BODMAS rule .
⠀⠀⠀⠀
BODMAS rule states the correct sequence to solve an equation . First we need to solve the bracket part then solve if any of is present moving further to division then multiplication carrying with addition atlast subtraction
⠀⠀⠀⠀
In this equation we will solve the bracket then we will apply further BODMAS rule
⠀⠀⠀⠀
━━━━━━━━━━━━━━━━━
SolutiOn :
➠ 7x + 31 = 8x - 1 ( 27x + 3 ) -3
➠ 7x + 31 = 8x - 27x - 3 - 3
Now, we will bring the variable on left hand side and constants on right hand side
➠ 7x - 8x + 27x = - 31 - 3 - 3
➠ 26x = -37
➠ x = -37/ 26
➠ x = - 1.42
∴ The value of x is -1.42 .

Give the slope of any line that is perpendicular to the line y = -1/8 x + 5
Answer:
8
Step-by-step explanation:
To find a slope for a line that is perpendicular to another line, you simply need to take the negative reciprocal of the the original line's slope. In this case we are already given the slope as the coefficient to x: -1/8. The negative reciprocal of that is 8/1, or just 8.
ANSWER ASAP!!! A trash compactor can compress 2/3 kilograms of trash in 1 minute. How many minutes would it take to compress 1/4 kilograms?
A. 1/4 × 2/3 = 1/6
B. 2/3 + 1/4 = 11/12
C. 1/4 ÷ 2/4 = 3/8
D. 2/3 ÷ 1/4 = 8/3
Time taken to compress 1/4 kilogram trash = 3/8 minutes
The correct option is C.
What is division?The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups.
Given,
Trash compactor can compress 2/3 kilogram trash in 1 minute
Time to compress 1 kilogram = 1 ÷ 2/3
Time to compress 1/4 kilogram = 1/4 × 1 ÷ 2/3 = 1/4 ÷ 2/3
= 1/4 × 3/2 = 3/8 minutes
Hence, 3/8 minutes is the time taken to compress 1/4 kilograms of trash.

Robert and his younger sister are selling gift wrap to raise funds for the middle school band. Robert's sales are 2.5 times his sister's sales. Their total sales together can be represented by the equation x+2.5x=63 . Which of these statements are true? Choose ALL that are correct. A Robert's sales are represented by x when solving 3.5x=63 . B Robert's sister's sales total $18.00. C Robert's sales are represented by x when solving 2.6x=63 . D Robert's sales total $25.20. E Robert's sister's sales are represented by x when solving 3.5x=63 .
Answer:
B. Robert's sister's sales total $18.00.
E. Robert's sister's sales are represented by x when solving 3.5x = 63 .
Step-by-step explanation:
Let
Robert sister's sales = x
Robert sales = 2.5 * x
= 2.5x
Total sales = Robert sister's sales + Robert sales
63 = x + 2.5x
63 = 3.5x
Divide both sides by 3.5
x = 63 ÷ 3.5
= 18
x = $18.00
Robert sales = 2.5x
= 2.5(18)
= $45.00
A. Robert's sales are represented by x when solving 3.5x=63 .
No
B. Robert's sister's sales total $18.00.
Yes
C. Robert's sales are represented by x when solving 2.6x=63 .

Factorise the following:
a) x^2 - 5x - 6
b) x^2 + 3x – 40
c) x^2 - 7x - 30
Answer:
a) (x+6)(x-1)
b) (x+8)(x-5)
c) (x+3)(x-10)
Step-by-step explanation:
The final answer would always have to be two brackets with x and the relevant variables.
x²: You know the possible factors that can be multiplied together would be x and x. Each factor would have to be in different brackets, so we get (x + smth else)(x +smth else)
When factorising quadratic expressions, you need to find the correct pair of factors, that when multiplied together, becomes the constant of the expression. They also need to become the middle term when they are multiplied with the term in the bracket and then added together.
Possible factors for a):
1. 1 × 6 = 6
2. 2 × 3 = 6
You know 1 - 6 = -5, so we shall use the factors 6 and 1.
(x+6)(x-1) = x² -x + 6x - 6
= x² + 5x - 6
Thus, (x+6)(x-1) is the answer.
Possible factors for b):
1. 1 × 40 = 40
2. 2 × 20 = 40
3. 4 × 10 = 40
4. 5 × 8 = 40
You know 8 - 5 = 3, so we shall use the factors 8 and 5.
(x+8)(x-5) = x² -5x + 8x - 40
= x² + 3x - 40
Thus, (x+8)(x-5) is the answer.
Possible factors for c):
1. 1 × 30 = 30
2. 2 × 15 = 30
3. 3 × 10 = 30
4. 5 × 6 = 30
You know 3 - 10 = -7, so we shall use the factors 3 and 10.
(x+3)(x-10) = x² -10x + 3x - 30
= x² - 7x - 40
Thus, (x+3)(x-10) is the answer.
a)
x² - 5x - 6
= x² + x - 6x - 6
= x(x + 1) -6(x + 1)
= (x - 6) (x + 1)
b)
x² + 3x - 40
= x² + 8x - 5x - 40
= x(x + 8) -5(x + 8)
= (x - 5) (x + 8)
c)
x² - 7x - 30
= x² - 10x + 3x - 30
= x(x - 10) + 3(x - 10)
= (x + 3) (x - 10)

A city planner is mapping out some new features for a triangular park. She sketches the park on grid paper. The coordinates of the vertices of the park are (1, 1), (1, 4), and (−3, 4). The city planner wants to put a flower bed at the centroid of the park. What are the coordinates of the flower bed? (__,__)
Answer:
The coordinates of the flower bed are ([tex]-\frac{1}{3}[/tex] , 3)
Step-by-step explanation:
To find the centroid of a triangle, use this rule centroid = ([tex]\frac{x1+x2+x3}{3},\frac{y1+y2+y3}{3}[/tex]), where (x1, y1), (x2, y2), (x3, y3) are the vertices of the triangle
∵ The vertices of the triangle are (1, 1), (1, 4), (-3, 4)
∴ x1 = 1 and y1 = 1
∴ x2 = 1 and y2 = 4
∴ x3 = -3 and y3 = 4
→ Substitute them in the rule above
∵ Centroid = ([tex]\frac{1+1+-3}{3},\frac{1+4+4}{3}[/tex])
∴ Centroid = ([tex]\frac{-1}{3},\frac{9}{3}[/tex])
∴ Centroid = ([tex]-\frac{1}{3}[/tex] , 3)
∴ The coordinates of the flower bed are ([tex]-\frac{1}{3}[/tex] , 3)
