Is it possible for triangle JKL to be similar to triangle XYZ Explain.
Answer: Yes it is possible for triangle JKL to be similar to triangle XYZ.
Step-by-step explanation:
Given: In ΔJKL
m∠J=71° , m∠K=52°
In ΔXYZ
m∠X=71° , m∠Z=57°
Using Angle sum property of triangle in ΔJKL, we have
m∠J+m∠K+m∠L=180°
⇒71°+52°+m∠L=180°
⇒m∠L=180°-123°
⇒m∠L=57 °
Now in ΔJKL and ΔXYZ , we have
m∠J=m∠X=71°
and m∠L= m∠Z=57°
Therefore , By AA-similarity criteria , we have
ΔJKL≈ΔXYZ
Hence, Yes it is possible for triangle JKL to be similar to triangle XYZ.

A road crew can repave 1/56 miles of road each hour. They must repave a road that is 7/8 miles long. How long will it take the crew to repave the road?
Answer: 49 hours
Step-by-step explanation:
Given : A road crew can repave [tex]\dfrac{1}{56}[/tex] miles of road each hour.
i.e. the rate of of repave = [tex]\dfrac{1}{56}[/tex] miles per hour.
Distance required to cover = [tex]\dfrac{7}{8}[/tex] miles.
The formula used here is :-
[tex]\text{Time}=\dfrac{\text{Distance}}{\text{rate of repave}}[/tex]
i.e. [tex]\text{Time}=\dfrac{\dfrac{7}{8}}{\dfrac{1}{56}}[/tex]
i.e. [tex]\text{Time}=\dfrac{7}{8}\times56=7\times7=49[/tex]
Hence, it will take 49 hours to repave the road.

Phil received a prize of x dollars from a poker tournament. The tournament cost him 100 dollars to enter. What were Phil's net winnings from the tournament? Write your answer as an expression.
Phil's net winnings from the poker tournament are represented by the expression 'x - 100', where x is the prize amount he won. To calculate his actual profit, we subtract the cost of entry (100 dollars) from his prize money.
Explanation:The student has asked what Phil's net winnings are from a poker tournament after he received a prize of x dollars and the entry to the tournament cost him 100 dollars. To answer this, we will create an expression to represent Phil's net winnings.
Net winnings are calculated by subtracting the cost of entering the tournament from the prize amount. Since Phil won x dollars and spent 100 dollars to enter, we subtract 100 from x.
Phil's net winnings = Prize amount - Entry cost
Phil's net winnings = x - 100 dollars
This expression shows the actual profit Phil made from participating in the tournament, after the cost of entry has been accounted for.
Final answer:
Phil's net winnings from the poker tournament can be expressed as x - 100, where x represents the prize money.
Explanation:
To find Phil's net winnings from the poker tournament, we need to calculate the difference between the prize money and the entry fee. Given that Phil received a prize of x dollars and the tournament cost him 100 dollars to enter, his net winnings can be expressed as:
x - 100
For example, if Phil won $500, his net winnings would be $500 - $100 = $400.

PLEASE HELP!!!
To compare the amount of paint Enya would use to paint all but the bottom surface of the storage cupboard to the amount she would use to paint the entire prism, calculate the surface area of the prism and the surface area of all but the bottom surface of the prism. Then, divide the surface area of all but the bottom surface by the surface area of the entire prism and multiply by 100. Round the final answer to the nearest tenth.
Explanation:To compare the amount of paint Enya would use to paint all but the bottom surface of the storage cupboard to the amount she would use to paint the entire prism, we need to calculate the surface area of the prism and the surface area of all but the bottom surface of the prism.
Step 1: Calculate the surface area of the prism by adding the areas of all its faces. The prism has two rectangular faces with dimensions 2.3 ft by 3.6 ft, two rectangular faces with dimensions 2.3 ft by 2.3 ft, and one rectangular face with dimensions 3.6 ft by 2.3 ft.
Step 2: Calculate the surface area of all but the bottom surface of the prism by subtracting the area of the bottom surface from the total surface area of the prism. The bottom surface has dimensions 2.3 ft by 2.3 ft.
Step 3: Calculate the percentage by dividing the surface area of all but the bottom surface of the prism by the surface area of the entire prism and multiplying by 100. Round the final answer to the nearest tenth.

How to simplify equation with 2 parenthesees multiplication?
Answer:
Distributive Property
Step-by-step explanation:
Use the distributive property to multiply each term in each parenthesis.
Example:
To simplify the expression (x-3)(x^2-4x-7), apply the distributive property. The distributive property states to multiply each term in each parenthesis.
x*x^2=x^3
x*-4x=-4x^2
x*-7=-7x
-3*x^2=-3x^2
-3*-4x=12x
-3*-7=21
This gives the expression x^3-4x^2-7x-3x^2+12x+21. Combine like terms and get x^3-7x^2+5x+21.

The plane with an inclined an 12°
Let's suppose the Galileo walk x meters up the inclined plane.
As per right angle triangle, The ratio of Sin
[tex]\rm Sin12\° = \frac{100}{x}[/tex]
[tex]\rm x = \frac{100}{Sin12\°}[/tex]
Sin12° = 0.20791
x = 100/0.20791
x = 480.97 meters or
x = 481 meters

Use the substitution method to solve the system of equations. Choose the correct ordered pair. x + 2y = 12 –x = –y – 6
A. (9, 3)
B. (7, 1)
C. (6, 0)
D. (8, 2)
Answer: D
Step-by-step explanation:
The ordered pair of the system of equations is (8, 2).
Option D is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
x + 2y = 12 _____(1)
x = 12 - 2y _____(2)
-x = -y - 6 _______(3)
Putting (2) in (3) we get,
-(12 - 2y) = -y - 6
-12 + 2y = -y - 6
-12 + 6 = -y - 2y
-6 = -3y
y = 2
Now,
y = 2 in (2)
x = 12 - 2 x 2
x = 12 - 4
x = 8
Thus,
The ordered pair is (8, 2).

Which shows two triangles that are congruent by ASA?
The second one, as shown in the attached picture.
Further explanationThe ASA (Angle-Side-Angle) postulate for the congruent triangles: two angles and the included side of one triangle are congruent to two angles and the included side of another triangle; the included side properly represents the side between the vertices of the two angles. The SAS (Side-Angle-Side) postulate for the congruent triangles: two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle; the included angle properly represents the angle formed by two sides.The SSS (Side-Side-Side) postulate for the congruent triangles: all three sides in one triangle are congruent to the corresponding sides within the other.The AAS (Angle-Angle-Side) postulate for the congruent triangles: two pairs of corresponding angles and a pair of opposite sides are equal in both triangles.- - - - - - - - - -
Notes
The angle-side-side postulate for the congruent triangles doesn't exist because an angle and two sides don't guarantee that two triangles are congruent. If two triangles have two congruent sides and a congruent non-included angle, then triangles don't seem to be necessarily congruent. This can be why there's no side-side-angle (SSA) and there's no angle-side- side postulate.The AAA (angle-angle-angle) postulate for congruent triangles does not work because having three corresponding angles of equal size is not enough to prove congruence.

−x^2 +5x
x^2+5x ^1/5
Answer:
[tex]6x^2+ 5x[/tex]
[tex]-x^2 +5x[/tex]
Step-by-step explanation:
Expression is a polynomial when it contains variables, numbers and operators. Expression that contains fractional exponent is not a polynomial. Expression with variable in the denominator is not a polynomial.
[tex]6x^2+ 5x[/tex]
It is a polynomial
[tex]-7x^2+ \frac{5}{3x}[/tex]
It is not a polynomial because x is in the denominator
[tex]-x^2 +5x[/tex]
It is a polynomial
[tex]x^2+5x ^ \frac{1}{5}[/tex]
It is not a polynomial because it has fractional exponent
The expressions that are polynomials include 6x² + 5x, −7x²+5/3x, and −x² +5x, because they have non-negative integer exponents and a finite number of terms. The expression x²+5x[tex]^{(1/5 )}[/tex]is not, due to the non-integer exponent.
The expressions that are polynomials must have non-negative integer exponents and a finite number of terms. Given the options:
6x² + 5x is a polynomial because the exponents are integers and it has a finite number of terms.
−7x²+5/3x is also a polynomial with non-negative integer exponents and finite terms.
−x² +5x is a polynomial as well, following the same reasoning.
x²+5x[tex]^{(1/5)}[/tex] is not a polynomial because the exponent 1/5 is not an integer.
Therefore, the expressions that are polynomials are 6x² + 5x, −7x²+5/3x, and −x²+5x.
