Is this proportional or nonproportional please tell me asap with right answer please

A triangle that has sides with lengths of 3cm, 6cm and 9cm is not a right-angled triangle.

In Mathematics, the Triangle Inequality Theorem is represented by this mathematical expression:

b - c < a < b + c

Where:

a, b, and c represent the side lengths of this triangle.

By applying the Triangle Inequality Theorem to the side lengths of this triangle, the right-angled triangle that can be formed would be determined as follows:

6 + 3 > 9

9 > 9 (False and not a right-angled triangle).

In conclusion, we can logically deduce that the two (2) short side lengths does not exceed the long side lengths and as such it is not a right-angled triangle.

The number of bags of oranges did Shannon use on Tuesday will be 3 bags.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Shannon operates an orange juice stand. On Monday she used 1 1/2 bags of oranges. On Tuesday she used 2 times as many oranges as on Monday.

The number of oranges will be calculated as,

⇒  2 × (1 ¹/₂)

⇒  2 × (1 + ¹/₂)

⇒  2 + 2 × ¹/₂

⇒  2 + 1

The image of the point (2, 3) in the line y=−x is (-3, -2).

Let there be a point P(2, 3) on the cartesian plane. The image of this point in the line y=−x will lie on a line that is perpendicular to this line and the distance of this point from y=−x will be equal to the distance of the image from this line.

Let Q be the image of p and let the co-ordinate of Q be (h, k)

The slope of line y=−x is −1

Line joining P, Q will be perpendicular to y=−x so, its slope =1.

Let the equation of the line be y=x+c since this passes through points (2,3)

3=2+c⇒c=1

and the equation y=x+1

The point of intersection R lies in the middle of P & Q. Point of the intersection of lines y=−x and y=x+1 is

2y =1 , y= [tex]\frac{1}{2}[/tex] and x = [tex]-\frac{1}{2}[/tex]

Hence, [tex]\frac{h+2}{2} = -\frac{1}{2}[/tex] and [tex]\frac{k+3}{2} = \frac{1}{2}[/tex]

⇒ h=−3 and k =−2

So, the image of the point (2, 3) in the line y=−x is (-3, -2).

The substitution principle in math we substitute the value of one variable with another one and solve the equation.

By changing the value of another variable in an equation, the variable can be eliminated using this method. Thus, the elimination by substitution method is the name given to this technique.

As we are aware, the substitution approach entails solving the equation to determine the value of the variable, which is then substituted in the other equation. The elimination approach, in contrast, involves removing variables from the equation such that the equation's system can be reduced to being the function of a single variable.

The length of this hammer is going to be 38cm

Length has the dimension of distance in the International System of Quantities. The majority of measuring systems choose a base unit for length from which all other units are derived.

The formula that we would use to get the length is

r₁ + r₂ = L

Where r₁  is the lenght 9 cm from the head

29 cm is the length from the bottom

When we add these two, we would have the length of the hammer

Both the triangles are not similar.

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.

Two triangles are comparable if they have two pairs of sides that are in the same ratio and if the included angles are likewise equal.

The square of any ratio between any two matching sides of two comparable triangles is equal to the ratio of their areas. As an illustration, Area of ABC/Area of DEF equals (AB)2/(DE)2 = (BC)2/(EF)2 = (AC)2(DF)2 for any two comparable triangles ABC and DEF.

The finance charge on Rachel's loan can be calculated by multiplying the loan amount by the interest rate and then multiplying by the loan term (in months).

Finance Charge = (Loan Amount x Interest Rate x Loan Term)

Finance Charge = ($4,500 x 0.12 x 36 months)

Finance Charge = $6,230.16

The finance charge on Rachel's loan can be calculated by multiplying the loan amount by the interest rate and then multiplying by the loan term (in months). In this case, Rachel took out a $4,500 loan with a 12% annual interest rate for 36 months. The total finance charge for this loan can be calculated as follows: Finance Charge = ($4,500 x 0.12 x 36 months) = $6,230.16. This means Rachel will need to pay a total of $10,730.16 to pay off the loan, including the finance charge.

2 fingers dilation is normally 2 cm in measurement.

Dilation is the process of increasing an object's size without altering its form. Depending on the scale factor, the object's size may rise or shrink. A square of side 5 units can be widened to a square of side 15 units using dilation math, but the square's form doesn't change.

A dilation is a function f from a metric space M into itself that, for any locations x, y in M, fulfills the identity d=rd, where d is the distance between x and y and r is a positive real integer. Such a dilatation is a resemblance of the space in Euclidean space.

Meaning of Dilation in Math. Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is a picture with the same shape as the original. However, there is a variation in the shape's size.

The sum of the additive inverse of 29 and 61 is equal to -90.

The sum of the additive inverse of two numbers is equal to zero. The additive inverse of a number is the (opposite) number which when added to the original number yields zero. The formula for calculating the additive inverse of a number is additive inverse (x) = - x. The additive inverse of 29 and 61 can be calculated using the formula, additive inverse (29) = -29 and additive inverse (61) = -61.

Therefore, the sum of the additive inverse of 29 and 61 will be -29 + -61 = -90. This can be confirmed by adding 29 and 61 which will yield 90 and then subtracting 90 from zero to yield -90. In other words, the sum of the additive inverse of 29 and 61 is equal to -90.

What is the ratio?

Equivalent ratios are those that are the same when compared. Two or more ratios can be compared to determine whether or not they are equal. For example, the ratios 1:2 and 2:4 are equivalent.

Given that,

Number of Gallons of Blue Paint:  5     7   9   12             33

Number of Gallons of Red Paint   10    14  18   24          66

The ratio of the number of gallons of red paint to the number of gallons of blue paint in shade B is 66: 33 = 2:1.

It means for every 2 gallons of red paint for every 1 gallon of blue paint.

The ratio of the number of gallons of red paint to the number of gallons of blue paint in shade A is 90:60 = 3:2.

It means for every 3 gallons of red paint for every 2 gallons of blue paint.

The total gallon in shade A is (60 + 90) = 150.
