The Elephant Building is 335 feet high. A real Asian elephant is 12 feet tall. If 29 real elephants could stand on top of each other, would they reach the top of the building?
They are asking if 29 12' elephants are as tall as as a 335' building:
29 × 12' = 348' elephant stack
because 348' is taller than 335' building then yes, 29 staked elephant would reach and pass the top of a 335' building.
What’s The Value Of X as A Decimal
Step-by-step explanation:
8x + 32 = 12x +19
4x = 13
x = 3.25
Find the value of x
(A) x= 135
(B) x= 25
(C) x= 35
(D) x= 90
Answer:
C) 35
Step-by-step explanation:
The sum of the interior angles of a triangle is 180°. We also have a right angle which is 90°.
2x - 8 + 90 + x -7 = 180 Combine like terms
3x + 75 = 180 Subtract 75 from both sides
3x = 165 Divide both sides by 3
x = 35
Pointss!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Step-by-step explanation:
always remember (for your life) : the sum of all angles in a triangle is always 180°.
and the sum of all angles around a single point on one side of a line is also always 180°.
so,
180 = 65 + 51 + angle PSR
angle PSR = 180 - 65 - 51 = 64°
angle PST is the supplementary angle to angle PSR (that means together they have 180°), because of the principle of all angles around a single point (S) on one side of a line (TSR).
so,
180 = angle PST + angle PSR = angle PST + 64
angle PST = 180 - 64 = 116°

Augustina has 2 posters with length x inches.
One poster has a width of x + 5 inches, and
the other has a width of x + 7 inches. Write an
expression to represent the area of wall that the
posters will cover.
Answer:
2x² + 12x
Step-by-step explanation:
Area of rectangle:Area of rectangle = length * width
Poster 1:
length = x inches
widht = (x + 5) inches
Area of poster 1 = x * (x + 5)
= x*x + x*5 {Distributive property}
= x² + 5x square inches
Poster 2:
length = x inches
width = (x + 7) inches
Area of poster =x *(x+ 7)
= x*x + x*7
= x² + 7x
Area of wall = area of poster1 + area of poster 2
= x²+ 5x + x² + 7x
= x² + x² + 5x + 7x {Combine like terms}
= 2x² + 12x
Answer:
[tex]2x^2+12x[/tex]
Step-by-step explanation:
Dimensions of Poster 1:
Length = x inchesWidth = (x + 5) inchesDimensions of Poster 2:
Length = x inchesWidth = (x + 7) inchesThe posters can be modeled as rectangles.
[tex]\boxed{\textsf{Area of a rectangle}=\sf length \times width}[/tex]
Therefore, the expressions for the area of each poster are:
[tex]\implies \textsf{Area of Poster 1}=x(x+5)[/tex]
[tex]\implies \textsf{Area of Poster 2}=x(x+7)[/tex]
Therefore, the expression that represents the area of the wall that the posters will cover is the sum of the expressions of the areas of the individual posters:
[tex]\begin{aligned}\textsf{Area of wall posters will cover}&=\textsf{Area of Poster 1}+\textsf{Area of Poster 2}\\& = x(x+5)+x(x+7)\\&=x^2+5x+x^2+7x\\&=x^2+x^2+5x+7x\\&=2x^2+12x\end{aligned}[/tex]
Write a two-column proof to prove that vertical angles are congruent.
The manipulatives and paragraph forms are the two-column proof to prove that vertical angles are congruent.
Using manipulatives: Draw the same two intersecting lines on the paper. Then, fold the paper along the line via the joint. The fold bisects the other two borders, but only the lines of the folded border which are on top of each other are required. The edges check and lie straight on top of each separately. This folding procedure can be utilized with two vertical corners. As a result, the vertical angles are the same.
Paragraph Form: When ∠1 and ∠3 are connected to ∠2, they form a linear pair. This indicates that whether added dimension ∠2 to dimension ∠1 or dimension ∠2 to dimension ∠3, the total is 180°. That is, the measures of 1 and 3 are equal to the sum left before adding ∠2. As a result, the angles are the same. This argument applies to all pairs of vertical angles.

the nth term of a sequence is givin by 3n2
position of the term that is the first one to have a value over 100
Position of 1083 is 19 in the sequence that is the first one with a value greater than 1000.
What is Sequence?
A list of numbers or objects in a special order is called sequence.
Given that;
The nth term of a sequence = 3n²
Now,
Let [tex]a_{n}[/tex] be the nth term.
Then, [tex]a_{n} = 3n^{2}[/tex]
Let m be the term which is the first term with a value greater than 1000.
Then, [tex]a_{m} > 1000[/tex]
Substituted the value of [tex]a_{m}[/tex] we get;
3m² > 1000
Divide by 3 we get;
m² > 1000/3
m² > 333.333
Take square root both side;
m > √333.33
m > 18.25
Thus, m = 19
So, 19th term is the first one with a value greater than 1000.
Hence, [tex]a_{19} = 3(19)^2 = 3 * 361 = 1083[/tex]
Thus, Position of 1083 is 19 in the sequence that is the first one with a value greater than 1000.

Jamal hypothesized that when adding two unit fractions together, he can determine the numerator by adding the two denomimators together, thrn could find the new denominator by multiplying the old denominators together. Prove jamal correct. What are some drawbacjs of jamals shortcut?
Jamal is correct ( ½+⅓ =⅚), when he says that when adding two unit fractions, the numerator is found by adding the denominators, and the new denominator can be found by multiplying the previous denominators.
State what is denominator with example?A denominator is the lowest number in a fraction that indicates how many equal parts are divided into a whole. It is a fraction's divisor. In this case, the denominator is 4, thus there are four components overall.
What is an illustration of a numerator?In a fraction, the number above the line is the numerator. For instance, the numerator of the fraction 3/5 is 3. A fraction's numerator displays the number of pieces that make up the whole while the denominator.
Adding 2 unit fractions example ½ and ⅓

Find the Area of the figure below, composed of a square and four semicircles. Rounded to the nearest tenths place
The Area of the figure ,composing of a square and four semicircles is 832.7 sq. units
The Length of the side of the square is 18 units which is also the diameter of the semicircle.
So, The Area of square is Length * Length = 18*18 = 324 sq. units
Now, the radius of semicircle = 0.5(diameter)= (0.5)*18 = 9 units
The area of semicircle = half of area of circle = (0.5)3.14(radius)(radius)
The area of one semicircle = (0.5)3.14(9)(9)
The area of one semicircle = 127.17
The Total area of figure consists of 4 semicircles and one square
So, Total area = 4(area of 1 semicircle) + area of square
Total area = 4(127.17) + 324
Total area = 832.68 sq. units
rounding off the total area = 832.7 sq. units
Therefore, the total area of the given figure is 832.7 sq. units.

To prove that △LMN ~ △XYZ by the SAS similarity theorem, it also needs to be shown that
For both triangles to be proven to be similar to each other by the SAS similarity theorem, it also needs to be shown that: A. angle N ≅ angle Z.
What is the Side-angle-side Similarity Theorem (SAS)?The side-angle-side similarity theorem (SAS) states that two triangles can be proven to be similar to each other if two pairs of corresponding sides of the two triangles are proportional to each other and one pair of corresponding angles of the two triangles are congruent to each other.
In the image given, we know that in both triangles:
XZ/LN = 6/2 = 3
ZY/NM = 9/3 = 3
Therefore:
XZ/LN = ZY/NM = 3
This means that the two triangles have two pairs of corresponding sides that are proportional to each other.
Thus, we also need to show that both triangles have a pair of congruent included angles before we can prove both triangles are similar to each other.

Not all possible values of the domain may be covered by an operation's definition. For instance, it is impossible to square the roots of negative numbers or divide by zero in real numbers. An operation's domain of definition, also known as the active domain, is the set of values for which the operation is specified. However, the set of real values obtained by the operation is its codomain of definition, active codomain, image, or range. The set that contains the values created is referred to as the codomain. For instance, only non-negative numbers are produced by the squaring operation when applied to the real numbers; the set of real numbers is the codomain, but the non-negative numbers are the range.
