Answer: 12m by 4m.
Step-by-step explanation: You are looking for the dimensions of the room here, also known as the length and width.
Let’s make width equal to x since we don’t know what the value is. Length is going to be x + 8 since the diagonal is 8m MORE than the width.
w = x
l = x + 8
Use the equation for the perimeter.
P = 2l + 2w
Plug in your values:
32 = 2(x + 8) + 2(x)
Now, solve for x! First start by distributing the 2:
32 = 2x + 16 + 2x
Next, add like terms:
32 = 4x + 16
Subtract 16 from both sides:
16 = 4x
Divide by 4 on both sides:
4 = x
Now we have x, but remember, x is equal to the width. We just solved for width so now we need length.
l = x + 8
Plug in your x and solve:
l = 4 + 8
l = 12
Your length is 12m and your width is 4m, therefore, the dimensions of the rectangular room are 12m by 4m.
What’s the answer???
find the value of X also show the process please

A black bar with 5 copper colored coils around it.
A black bar with 2 copper colored coils around it.
A black bar with 7 copper colored coils around it.
A black bar with 4 copper colored coils around it
Answer:
c
Step-by-step explanation:
A black bar with 7 copper colored coils around it is the strongest.
What is an Electromagnet?Electromagnets are defined as magnet which works through electricity.
We know permanent magnets show magnetic properties every time. We cannot alter it. But electromagnets only acts as a magnet when current passes through it. Otherwise, it is just a coiled wire.
Strength of electromagnet depends on basically two things:
First, the amount of current flowing through the wire and
Second, the number of turns of wire around the coil.
Here there are four electromagnets which are black bar with 5, 2, 7 and 4 copper colored coils around it.
Number of coils is maximum for the black bar with 7 copper colored coils around it, which results in the strongest electromagnet.
Hence, a black bar having 7 copper colored coils around it is the strongest.

Does this graph show a function??
Answer:
yes
Step-by-step explanation:
the function does not cross the same point of x twice.
Answer:
B.) Yes; The graph passes the vertical line test!
Step-by-step explanation:
This graph does indeed show a function! A parabola, it looks like!
A function on a graph is determined when the function passes the vertical line test, meaning no matter where you go on the function, a specific vertical line will only pass through one point!

A metronome uses an inverted pendulum rod to control tempo. A weight can be slid up the pendulum rod to decrease tempo, or down the pendulum rod to increase tempo. A second fixed weight is hidden inside the metronome at the base of the pendulum. The longer the distance between the two weights, the slower the tempo. This equation is used to calculate the frequency of the metronome pendulum:
[tex]f = \frac{ \sqrt{ \frac{g}{l} } }{2\pi} [/tex]
Each time the metronome's pendulum completes one back and forth cycle, it produces two ticks or beats. To calibrate the metronome for beats per minute (bpm) the manufacturer needs to know the length of the pendulum for various tempos. Solve
[tex]f = \frac{ \sqrt{ \frac{g}{l} } }{2\pi} [/tex]
for L.
Answer:
Part 1
Multiply both sides by 2π
2πf = √(g/L)
Square both sides
4π²f²= g/L
Invert both sides
1/(4π²f²) = L/g
Multiply both side by g
g/(4π²f²) = L
We usually write an equation with the subject (L) n the left
L = g/(4π²f²)
________________________
Part 2
Using the above equation with the given values:
L = g/(4π²f²)
. .= 9.8 / (4π² x 1.6²)
. .= 0.097m (= 9.7cm)
________________________
By the way, where it says
“f=1.6 then there are 2 beats a second, or 192 beats per minute (bpm).”
this should say
“f=1.6 then there are 3.2 beats a second, or 192 beats per minute (bpm)”
Step-by-step explanation:
The values are L = g/(4π²f²) and L.= 0.097m (= 9.7cm)
What is equation?
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Here, we have,
Part 1
Multiply both sides by 2π
2πf = √(g/L)
Square both sides
4π²f²= g/L
Invert both sides
1/(4π²f²) = L/g
Multiply both side by g
g/(4π²f²) = L
We usually write an equation with the subject (L) n the left
L = g/(4π²f²)
________________________
Part 2
Using the above equation with the given values:
L = g/(4π²f²)
L.= 9.8 / (4π² x 1.6²)
L.= 0.097m (= 9.7cm)
Hence, The values are L = g/(4π²f²) and L.= 0.097m (= 9.7cm).

What is the equation, in point-slope form, of the line
that is perpendicular to the given line and passes
through the point (-4, -3)?
A: y + 3 = -4(x + 4)
B: y + 3 = -1/4(x+4)
C: y + 3 = 1/4(x + 4)
D: y + 3 = 4(x + 4)
Answer:
C: y + 3 = 1/4(x + 4)
Step-by-step explanation:
Perpendicular to a given line means opposite inverse of the slope...
Equation of line is: y = -4x - 3
slope in above equation is -4, perpendicular would be 1/4
Perpendicular equation of a line through P(-4, -3):
y = mx + b
-3 = 1/4(-4) + b
-3 = -1 + b
b = -2
Use perpendicular slope and the b from above to form the perpendicular equation of line:
y = 1/4x - 2
Check:
(-3) = 1/4(-4) - 2
-3 = -1 - 2
-3 = -3

Answer:
530.66 inches²
Step-by-step explanation:
How do we find the radius?
The radius if 1/2 of the diameter, so 26/2 = 13 inchesHow do we find the area of a circle?
The area of a circle is πr², where r = radius. We are given the radius as 13 inches, and pi is approximated to 3.14.Solving
[tex]3.14*13^2[/tex] [tex]3.14*169[/tex] [tex]530.66[/tex]Therefore, the answer is 530.66 inches².
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Solution:
We know that:
Diameter = 26 in.Radius = Diameter/2Area of circle = πr²Finding the radius of the circle.
Radius = Diameter/2=> Radius = 26/2 = 13 in.Finding the area of the circle.
Area of circle = πr²=> Area of circle = (3.14)(13²)=> Area of circle = 3.14 x 169=> Area of circle = 530.66 in²find points and graph the line 3y=-x-3,3y=−x−3, following the instructions below.

Ok. First, let's find the slope using the slope formula.
[tex]m = \frac{y2-y1}{x2-x1} =\frac{9-5}{2-2} = 4/0[/tex]
4/0 is undefined.
When the slope is undefined, that means that it's a straight line going down from the x.
So the equation is just x = 2

Write the equation of the line in slope-intercept form that passes through the following points.
(4, 7) and (1, -2)
Answer:
y= 3x - 5
Step-by-step explanation:
coordinates given: (4,7) & (1, -2)
to find m (slope) = rise/run = (y2-y1) /(x2-x1)
= ( -2-7) / (1 - 4)
= -9/-3
= 3
therefore, y=3x + b
to find b:
taken coordinate: (4,7)
y=3x + b
7=3 (4) + b
7= 12 + b
7-12 = b
-5 = b
(*the value of b will be same even if we take the other coordinate)
therefore, y = 3x -5

What are the values of s and t?
Answer:
s=144
t=36
Step-by-step explanation:
you minus 180 from 36 and you get 144 for s
then you minus 180 from 144 to get t
Answer:
t = 36°
s = 108°
Step-by-step explanation:
FE and DE are congruent. This means that triangle ΔDEF is isosceles.
Base angles (∠EFD and ∠EDF) in isosceles triangles are congurent.
∠EFD is 36°. This means that ∠t is also 36°
The measure of all the angles in a triangle is 180°
[tex]36+36+x=180\\72+x=180\\x=108[/tex]
∠s = 108°
i need help asap, pls help!!
Answer:
see below
Step-by-step explanation:
Since the triangles are congruent
<A = <X
< B = < Y
<C = < Z
That means B = Y = 90
And C = Z = 37
The sum of the angles of a triangle are 180
A+ B+ C = 180
A + 90+37 = 180
A +127 = 180
A = 180-127
A =53
A = X = 53
We also know
AB = XY
BC = YZ
AC = XZ
AB = 3 so XY =3
YZ = 4 so BC =4
XZ = 5 so AC = 5
