I'm assuming you've already learned the special properties of a 30-60-90 triangle.
By drawing a 30-60-90 triangle by constructing line BC, and using the special proportions that come from it, we can find that
AB=AC/2=36/2=18
and
BC=AB*[tex]\sqrt{3}[/tex]=[tex]18\sqrt{3}[/tex]

1. Find the slant height of a square pyramid with a surface area of 57 square feet and a base perimeter of 12 feet
Answer:
Slant height = 8 feet.
Step-by-step explanation:
If the perimeter of the square base = 12 then each side of the base = 12/4
= 3 feet and its area = 3*3 = 9 ft^2
The area of one of the triangular sides = 1/2 * 3 * h where h is slant height.
So total surface area = 57 = 9 + 4 * 1.5h
9 + 6h = 57
6h = 48
h = 8 feet.

Answer:
AC = 2
BC = [tex]2\sqrt{2}[/tex]
CD = 4
CF = 4
BD = [tex]2\sqrt{2}[/tex]
DE = 8
EF = [tex]4\sqrt{2}[/tex]
DF = [tex]4\sqrt{2}[/tex]
Step-by-step explanation:
Since all of these are isosceles triangles, it means both legs of every triangle are congruent to each other. So,
Given: AB = 2
Find:
AC = AB = 2
BC = [tex]2\sqrt{2}[/tex]
CD = 4
CF = CD = 4
BD = BC = [tex]2\sqrt{2}[/tex]
DE = 8
EF = [tex]4\sqrt{2}[/tex]
DF = EF = [tex]4\sqrt{2}[/tex]
Twenty words are chosen randomly from a fifth-grade science book. Twenty random words are also chosen from a ninth-grade science book. The length of the words chosen are as follows:
5th Grade Textbook: 2, 4, 3, 6, 5, 5, 3, 7, 8, 4, 4, 1, 5, 2, 4, 1, 1, 4, 5, 3
9th Grade Textbook: 7, 9, 3, 4, 12, 9, 5, 3, 4, 3, 9, 4, 8, 6, 5, 7, 9, 4, 8, 6
By looking at the two data sets, which conclusion is reasonable?
Answer:
The 9th grade science book has, on average, longer words and, by extension, more difficult material covered than the fifth grade science book.

Find the common difference, d, given that 8x-3, 4x+1, 2x-2 are consecutive terms of an
arithmetic sequence.
A)1/6
B) -10
C) 10
D) 5
Answer:
B
Step-by-step explanation:
We are given that:
[tex]8x-3, \, 4x+1, \text{ and } 2x-2[/tex]
Are consecutive terms of an arithmetic sequence.
And we want to determine the common difference d.
Recall that for an arithmetic sequence, each subsequent term is d more than the previous term.
In other words, the second term is one d more than the first term. So:
[tex]4x+1=(8x-3)+d[/tex]
And the third term is two d more than the first term. So:
[tex]2x-2=(8x-3)+2d[/tex]
We can isolate the d in the first equation:
[tex]-4x+4=d[/tex]
As well as the second:
[tex]-6x+1=2d\Rightarrow \displaystyle -3x+\frac{1}{2}=d[/tex]
Then by substitution:
[tex]\displaystyle -4x+4=-3x+\frac{1}{2}[/tex]
Solve for x:
[tex]\displaystyle -x=\frac{-7}{2}\Rightarrow x=\frac{7}{2}[/tex]
The isolated first equation tells us that:
[tex]d=-4x+4[/tex]
Therefore:
[tex]\begin{aligned} \displaystyle d&=-4\left(\frac{7}{2}\right)+4\\&=-2(7)+4\\&=-14+4\\&=-10 \end{aligned}[/tex]
Our final answer is B.
Answer:
B.) - 10 is the answer.

Answer:
The equations 3·x - 6·y = 9 and x - 2·y = 3 are the same
The possible solution are the points (infinite) on the line of the graph representing the equation 3·x - 6·y = 9 or x - 2·y = 3 which is the same line
Step-by-step explanation:
The given linear equations are;
3·x - 6·y = 9...(1)
x - 2·y = 3...(2)
The solution of a system of two linear equations with two unknowns can be found graphically by plotting the two equations and finding the coordinates of the point of intersection of the line graphs
Making 'y' the subject of both equations gives;
For equation (1);
3·x - 6·y = 9
3·x - 9 = 6·y
y = x/2 - 3/2
For equation (2);
x - 2·y = 3
x - 3 = 2·y
y = x/2 - 3/2
We observe that the two equations are the same and will have an infinite number of solutions

What is an equation of the line that passes through the points (-1,3) and
(-1, 6)?
Please no links:)
Answer:
x = -1
Step-by-step explanation:
Slope = (6-3)/(-1- (-1)
= 3 / 0
- so the line is vertical.
- and as it passes through x axis at x = -1, the answer is x = -1.

Answer:
d = 637 ft below the surface
Step-by-step explanation:
Given
P = 14 + [tex]\frac{6}{13}[/tex] d
To find d when P = 308, then
14 + [tex]\frac{6}{13}[/tex] d = 308 ( subtract 14 from both sides )
[tex]\frac{6}{13}[/tex] d = 294 ( multiply by 13 to clear the fraction )
6d = 3822 ( divide both sides by 6 )
d = 637 ft
Answer:
637 feetStep-by-step explanation:
[tex]P=14+\dfrac6{13}d\\\\\\P=308\,,\qquad\qquad d=??\\\\\\308=14+\dfrac6{13}d\\\\ 308-14=\dfrac6{13}d\\\\294=\dfrac6{13}d\\\\d=294:\frac6{13}\\\\ d=294\cdot\frac{13}6\\\\d=637\,ft[/tex]

Las longitudes que se forman entre los vertices y el centro de un poligono regular son por favor respondan :'c
Answer:
Las longitudes que se forman entre los vértices y el centro de un polígono regular son;
Los radios del círculo circunscrito
Step-by-step explanation:
Cada círculo de radio, 'r', tiene un polígono que se puede inscribir polígono regular que tiene 'n' lados, donde n ≥ 3 y viceversa, todos los polígonos regulares se pueden inscribir (dibujar) en un círculo, que luego se conoce como la circunferencia del polígono
Dado que un polígono regular se puede inscribir en un círculo, de modo que sus vértices descansen sobre la circunferencia del círculo, entonces el centro del polígono es el centro del círculo que lo circunscribe.
Por lo tanto, las longitudes (iguales) que se forman entre los vértices y el centro del polígono regular son el radio del círculo que lo circunscribe..

Ben enters the water during a scuba dive. After 41 seconds of diving, his depth changes by - 29 feet. He wants to know his average change in depth each second. Write an expression for the average change in depth each second.
Answer:
-0.7073ft/sec
Step-by-step explanation:
Given the following
Distance covered by Ben = -29feet
Time taken = 41secs
Required
average change in depth each second(speed)
average change in depth each second = Distance/Time
average change in depth each second = -29/41
average change in depth each second = -0.7073ft/sec
Answer:
The answer is -29 divided by 41

Answer:
[tex]\sqrt{80}[/tex]
Step-by-step explanation:
Pythagorean theorem (Gougu theorem) states that the hypotenuse squared is equal to the sum of the squares of two other sides. (a^2 = b^2 + c^2). Hence x^2 = 4^2 + 8^2 = 80.
As x squared is 80, x is the square root of 80.
You can factorise this into 4[tex]\sqrt{5}[/tex]

Ο Α

D
Answer:
A
Step-by-step explanation:
We are given that:
[tex]\tan(\theta)=1.3[/tex]
And we want to find:
[tex]\cot(90^\circ -\theta)[/tex]
Remember that tangent and cotangent are co-functions. In other words, they follow the cofunction identities:
[tex]\tan(\theta)=\cot(90^\circ-\theta)\text{ and } \cot(90^\circ-\theta)=\tan(\theta)[/tex]
Therefore, since tan(θ) = 1.3 and cot(90° - θ) = tan(θ), then cot(90° - θ) must also be 1.3.
Our answer is A.

what is the slope of the line?
What is the y-intercept?
Write the equation of the line?
Answer:
The slope is 2
The y-intercept is 3
The equation is y = 2x +3
Step-by-step explanation:
The equation goes up 2 squares and over 1 square. 2/1 = 2
For y-intercept, look at the y-axis
The equation is supposed to be written as y = mx + b
m being the slope and b being the y-intercept.
How many right angles are there in an angle that turns through 360º?
4 right angles
90 + 90 + 90 + 90 = 360
However, it that figure is a circle-- it may include 0 right angles since circles have no angles.
