Answer:
D, 1600
Step-by-step explanation:
If ∆ABC≅∆DEF, and AB=15, BC=20, and FE=3x-7, then x=?
Answer:
x= 29
Step-by-step explanation:
Since, ∆ABC is congruent to ∆DEF,
AB= DE....(i)
BC= EF....(ii)
AC= DF....(iii)
From (ii), BC= EF,
So, 3x-7 = 20
3x= 20+7= 27
x= 27/3 = 9
Hope it helps you
From the congruent triangles value of x is 9 units.
Given that, ∆ABC≅∆DEF, and AB=15, BC=20, and FE=3x-7.
What is the congruence theorem?Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.
Since, ∆ABC is congruent to ∆DEF,
AB= DE --------(I)
BC= EF --------(II)
AC= DF --------(III)
From (II), BC= EF,
So, 3x-7 = 20
3x= 20+7= 27
x= 27/3 = 9 units
Therefore, from the congruent triangles value of x is 9 units.

The Line on the graph passes through the points A (1,3) and B (7,1)
Answer:
y = 3x-10
Step-by-step explanation:
gradient = (y2-y1) / (x2-x1)
substitute the values will give you:
(1-3)/(7-1) = -2/6 = -1/3
the gradient of a perpendicular line is always the negative reciprocal (multiply by -1 and flip the fraction), which will give you 3/1 = 3
now, let's find the y-intercept, we need to substitute x and y:
2 = (3x4) + c
c is the y-intercept
2 = 12 + c
c = -10

(a). The gradient of line AB = -1/2
(b). The gradient of a line perpendicular to AB = 2
(c). The equation of a line that passes through (4, 2) and perpendicular to AB is y = 2x -10.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂),
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
m = (1-3)/(7-3)
m = -1/2
The gradient of AB = -1/2.
The gradient of a line perpendicular to AB,
= negative reciprocal of slope of AB.
= 2.
Then the equation of a line that passes through (4, 2) and perpendicular to AB,
y - 2 = 2(x - 4)
y = 2x -8 - 2
y = 2x -10.
Therefore, all the required values are given above.

Answer:
350 adult tickets
Step-by-step explanation:
x = adult
x + 52 = children
x + x + 52 = 752
2x + 52 = 752
2x = 752 - 52
2x = 700
x = 700 / 2
x = 350
Hope that helps!
Answer:
a = 350 s = 402
Step-by-step explanation:
s + a = 752 where s is the number of student tickets and a = adult tickets
s = a + 52 since there were 52 more student tickets than adult tickets sold
so substitute for s: (a + 52) + a = 752, so 2a = 700 so a = 350
If adult tickets were 350 then the student tickets are 402
The walls in a square room are each 14 feet long. What is the distance from one corner of the room to the opposite corner?
Answer:
19.79 ft
Step-by-step explanation:
Given data
We are given that the dimension of the room is
Length= 14ft
Width= 14ft
Required
The Diagonal of the room
Applying the Pythagoras theorem we have
D^2= L^2+W^2
substitute
D^2= 14^2+14^2
D^2= 196+196
D^2= 392
D= √392
D= 19.79 ft
Hence the distance from one corner to the other is 19.79 ft

What is the equation of the line?
Answer:
3rd choice
Step-by-step explanation:
y = mx + b
Look at where the line crosses the y-axis. That is the y-intercept. It is 2, so b = 2, and you have
y = mx + 2
Now we need the slope, m.
Start at (0, 2). Go up 1 and right 2.
slope = m = rise/run = 1/2
Now you have
y = 1/2 x + 2
Answer: 3rd choice
Answer:
[tex]c)y=\frac{1}{2}x+2[/tex]
Step-by-step explanation:
[tex]We\ know\ that,\\The\ equation\ of\ a\ graph\ is\ given\ by\ the\ formula:\\y=mx+b,\ where\ m\ is\ the\ slope\ of\ the\ graph,\ and\ b\ is\ the\ y-intercept;\\Here,\\First,\\Lets\ calculate\ the\ slope\ of\ the\ graph:\\We\ also\ know\ that,\\Slope(m)=\frac{rise}{run}=\frac{y_2-y_1}{x_2-x_1}\\Lets\ consider\ any\ two\ points\ which\ lie\ on\ the\ line:\\(2,3),(-2,1)\\Hence,\\The\ slope\ of\ the\ given\ line=\frac{1-3}{-2-2}=\frac{-2}{-4}=\frac{1}{2}\\Hence,\\m=\frac{1}{2}\\[/tex]
[tex]Now,\\The\ y-intercept\ is\ the\ point\ at\ which\ the\ graph\ intersects\ the\ whole\ y-axis.\\Hence,\\Here,\\The\ line\ of\ the\ graph\ cuts\ the\ y-axis\ at\ (0,2).\\The\ y-intercept\ of\ the\ line=2\\Hence,\\The\ equation\ of\ the\ line:\\y=(\frac{1}{2})x+(+2)\\y=\frac{1}{2}x+2[/tex]

The Parthenon in Athens, Greece, is an ancient structure that has a rectangular base. The length of the base of the Parthenon is 8 meters more than twice its width. The area of the base is about 2170 square meters. Find the length and width of the base.
Answer: Length = 70 meters
Width = 31 meters
Step-by-step explanation:
Let the width of the rectangle be x.
Since the length of the base of the Parthenon is 8 meters more than twice its width. This will be: = 2x + 8
Area = 2170
Since length × width = area
(2x + 8) × x = 2170
2x² + 8x = 2170
Divide through by 2
x² + 4x = 1085
x² + 4x - 1085 = 0
x² + 35x - 31x - 1085 = 0
x(x + 35) - 31(x + 35) = 0
(x + 35) = 0 or (x - 31) = 0
x - 31 = 0
x = 0 + 31
x = 31
Width = 31 meters
Length = 2x + 8
= 2(31) + 8
= 62 + 8
= 70 meters
The rectangular base has a length of 70 meters and a width of 31 meters.
AreaArea is the amount of space occupied by a two dimensional object or figure. The area (A) of a rectangle is:
A = length * width
Let w represent the width, hence:
l = 2w + 8
Area = (2w + 8)w
2170 = 2w² + 8w
2w² + 8w - 2170 = 0
w = 31 m
l = 2(31) + 8 = 70 m
The rectangular base has a length of 70 meters and a width of 31 meters.
