physics convention 11 companies set up equal sized square booths in a row along one wall of a convention center.The booths are adjacent to each other and a 2-ft wide walkway surrounds the block of booths on three sides. The total area of the booths and walkway is 1200 ft^2. What is the side length of each booth?
Answers
Answer:
Side length of each booth is 8.35 ft approximately.
Step-by-step explanation:
There are 11 companies set up equal sized square booths in a row along one wall of a convention center.
Now, refer the diagram to answer the problem.
It is given area is 1200.
So, length x width =1200
(11x+24)(x+2)=1200
Multiply using FOIL method.
[tex]11x^{2}[/tex]+22x+24x+48=1200
[tex]11x^{2}[/tex]+46x+48-1200=0
[tex]11x^{2}[/tex]+46x-1152=0
Solve using quadratic formula
x=[tex]\frac{-46+/- \sqrt{46^{2}-4(11)(-1152 } }{2(11)}[/tex]
x=[tex]\frac{-46+/-\sqrt{2116+50688} }{22}[/tex]
x=[tex]\frac{-46+/-\sqrt{52804} }{22}[/tex]
Simplify it
[tex]x=\frac{-49+/- 229.79}{22}[/tex]
Simplify to get two values for x.
x=8.35; x=-12.67
Here negative does not work.
Side length of each booth is 8.35 ft.

Step-by-step explanation:
-8x+10x+20=0
2x+20=0
2x=0-20
2x=-20
x=-20/2
x= -10
Answer:
x = -10
Step-by-step explanation:
8x (-10x)= 10x +20 (-10x)
subtract 10x from both sides of the equation
-2x/-2 = 20/-2
divide both sides by -2
x = -10

Find the slope:
A.3/5
B.5/3
C-3/5
D.-5/3
Answers
Answer:
The slope of the line is [tex]\frac{-5}{3}[/tex] ⇒ D.
Step-by-step explanation:
The rule of the slope of a line is
m = [tex]\frac{y2-y1}{x2-x1}[/tex] (x1, y1) and (x2, y2) are two points lie on the lineUse the given figure to find two points on the line
→ From the given figure
∵ The line passes through points (0, 2) and (3, -3)
∴ x1 = 0 and y1 = 2
∴ x2 = 3 and y2 = -3
→ Substitute them in the rule of the slope above to find it
∵ m = [tex]\frac{-3-2}{3-0}=\frac{-5}{3}[/tex]
∴ m = [tex]\frac{-5}{3}[/tex]
∴ The slope of the line is [tex]\frac{-5}{3}[/tex]
Solve 6kx = 4kx + 8 for x.
Start by collecting the variable terms on the same side of the equation.
What is the first step?
Answers
Answer:
x = 4k
Step-by-step explanation:
6kx = 4kx + 8
The first step in solving for x is to get both numbers with kx on the same side. Move the 4kx to the left side of the = by subtracting 4kx from each side.
2kx = 8
Next, move the 2k to the right side of the = by dividing both sides by 2k
x = 8/2k
The last thing to do is to simplify the equation by making the 8/2 to 4/1 or 4.
x = 4k

Elena wants to make a scale drawing of her bedroom. Her bedroom is a rectangle with length 5 m and width 3 m. She decides on a scale of 1 to 50. Elena's bedroom door is 0.08 m. How wide should the door be on the scale drawing? Elena's bed measures 4 cm by 3 cm on the scale drawing. What are the actual measurements of her bed
Answers
Given:
Bedroom is a rectangle with length 5 m and width 3 m.
Elena's bedroom door is 0.08 m.
Elena's bed measures 4 cm by 3 cm.
Scale of drawing is 1 to 50.
To find:
The width of door on the scale drawing.
Actual measurements of her bed.
Step-by-step explanation:
Scale of drawing is 1 to 50.
It means, the length of sides in drawing is [tex]\dfrac{1}{50}[/tex] of actual.
Elena's bedroom door is 0.08 m.
1 m = 100 cm
0.08 m = 8 cm
Door on the scale drawing [tex]=\dfrac{1}{50}\times 8[/tex]
[tex]=0.16[/tex]
Therefore, the Door on the scale drawing is 0.16 cm wide.
Elena's bed measures 4 cm by 3 cm on the scale drawing.
Elena's bed actual measurements are
[tex]4\times 50=200cm=2m[/tex]
[tex]3\times 50=150cm=1.5m[/tex]
Therefore, the actual measurements of her bed is 2 m by 1.5 m.
