First image -Right triangle(One angle is 90 degrees)
Second image-Isosceles triangle(Two equal sides and two equal angles).
The side lengths of a triangle are 5,3, and 4. Is this a right triangle?
Answer:
YES
Step-by-step explanation:
as 5,3 and 4 are Pythagorean triplets, with 5 being C/the hypothenuse it would work as a right angled triangle.
3^2+4^2=c^2
9+16=c^2

A package of 8 notebooks costs $10.80. This equation can be used to determine the cost, n, in dollars, of each notebook in the package.
8n = 10.80
What is the cost, in dollars, of each notebook in the package?
Enter your answer in the box.
Answer:
$1.35
Step-by-step explanation:
8n = 10.80
Divide both sides by 8 to get n alone.
n = 10.80/8 = $1.35

[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}[/tex]
When solving an equation, we need to make sure that all variables are on the left-hand side, and all numbers are on the right-hand side.
Since we have numbers on both sides, we need to move all numbers to the right:-
[tex]\bold{5=\dfrac{10}{t} +3}[/tex]
[tex]\bigstar[/tex] Subtract 5 on both sides:-
[tex]\bold{0=\dfrac{10}{t} +3-5}[/tex]
[tex]\bigstar[/tex] On simplification,
[tex]\bold{0=\dfrac{10}{t} -2}[/tex]
[tex]\bigstar[/tex] Now, subtract 10/t on both sides:-
[tex]\bold{-\dfrac{10}{t} =-2}[/tex]
[tex]\bigstar[/tex] On simplification,
[tex]\bold{\dfrac{10}{t} =2}[/tex]
[tex]\bigstar[/tex] Multiply by t on both sides:-
[tex]\bold{10=2t}[/tex]
[tex]\bold{2t=10}[/tex]
[tex]\bigstar[/tex] Divide by 2 on both sides:-

By rounding to one significant figure, estimate the answer to these questions:
Answer:
To have one significant figure means to have one number with a significant value. Since all of the answers are greater than one, the final answer with the correct sig figs involves using the two leftmost numbers. If the second leftmost number is greater than 5, round the leftmost number up one unit. If the number is less than 5, leave the leftmost number alone. Finally, change all of the values besides the leftmost to zero. There should be no decimal place because having it would mean the zeros to the left of the decimal place are significant.

Select the correct answer from each drop-down menu. Graph shows 3 polygons on a coordinate plane. First polygon is at A(1, 1), B(2, 3), C(4, 3), D(3, 1). Second polygon prime ABCD is translated 2 units down and reflected. Third polygon double prime ABCD translated 2 units to the left and reflected. The figure shows three parallelograms: ABCD, A′B′C′D′, and A″B″C″D″. Polygon ABCD is to create parallelogram A′B′C′D′. Polygon ABCD is to create parallelogram A″B″C″D″.
The transformation that took place is a horizontal stretch by a factor of 2
How to explain the transformation?We are given that Polygon ABCD transformed to create polygon A'B'C'D'. Clearly, the polygon is first a translation of the polygon ABCD 1 unit to the right and then it is horizontally stretched by a scale factor of 2.
Since the length of the polygon was earlier 2 units and then the length of the Polygon A'B'C'D' is 4 units. Hence, the transformation that took place in the Polygon ABCD is a horizontal stretch by a factor of 2

A rectangle has an area of 243 square centimeters. Its length is 3 times its width. What are the dimensions of the rectangle?
Length - 27 cm
Width - 9 cm
Step-by-step explanation:Here we go (hope this helps),
The area of the rectangle is 243. To get area, you do length x width. Your equation will look like this
3x (x) = 243
Simplify this using PEMDAS
3x^2 = 243
Next, you divide both sides by 3 to undo the times 3
x^2 = 81
Then, you take the square root of both sides to undo the squared symbol
x=9
Using this, you know the width is 9. Since the length is 3x the width, you know that 3 x 9 is 27 and you can clearly see that the dimensions are 9 and 27!

Felipe and Samantha use a payment plan to buy musical instruments.felipe writes the equation y=-30x+290 to represent the amount owed y,after x payments.The graph shows how much Samantha owns after each payment Who will pay more each month
An equation is formed of two equal expressions. Felipe is paying $6 more each month.
What is an equation?
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The equation that represents Felipe's payment per month is given as y=-30+290, therefore, the amount that Felipe pays every month is the gradient of the line slope of the equation y=-30+290 which is 30.
Similarly, the graph showing Samantha's payment, the slope will be,
m = (y₂-y₁)/(x₂-x₁) = (240-0)/(0-10) = -24
Thus, we can conclude that Felipe is paying $6(30-24)more each month, because the amount paid by Felipe is 30, while the amount paid by Samantha is 24.
Hence, Felipe is paying $6 more each month.

Surface Ratio is the "Similarity Ratio" to the power of 2
Volume Ratio is the "Similarity Ratio" to the power of 3
It's logical and deductable by paying attention to the correlation between the "Side"s(or "Diameter"s) and the "Surface" and the "Volume"s in simple shapes like Circles and square.
By paying attention to the formula of the "Surface Area" and the "Volume" or the m /m^2 /m^3 ( the units of measurement) we can easily notice the relation.

The area of a rectangle is x² + 2x -15. If its length is x + 2 units, what is its width?
Length of the rectangle is 8 units
Step-by-step explanation:
Step 1: Find the length, let width be x.Area of the rectangle = 48 units
Length = x + 2
⇒ Area = Length × Breadth
48 = x (x + 2)
48 = x² + 2x
x² + 2x - 48 = 0
x² + 8x - 6x + 48 = 0 (Product Sum rule to factorise)
x(x + 8) - 6(x + 8) = 0
(x - 6)(x + 8) = 0
⇒ x = 6, -8 (negative value is neglected)
∴ x = 6
x + 2 = 8
