Answer:
x = 7 cm
Step-by-step explanation:
The two triangles are similar so ...
x/(6 cm) = (42 cm)/(36 cm)
Multiplying by 6 cm, you get ...
x = (6 cm)(42 cm)/(36 cm) = (6 cm)(7/6)
x = 7 cm
Each chair or table requires between 0.2 and 1 gallon of paint to be painted.
What is the equivalent expression?
Equivalentexpressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
To find out how many gallons of paint are used to paint each piece of furniture, we need to divide the total amount of paint used by the total number of pieces of furniture.
Let x be the amount of paint used to paint one chair or table, in gallons.
Then, for 20 chairs and 5 small tables, the total amount of paint used is:
4 gallons = 20x + 5x
Simplifying this equation, we get:
4 gallons = 25x
Dividing both sides by 25, we get:
x = 0.16 gallons
Therefore, it takes 0.16 gallons of paint to paint each chair or table. Since we are looking for whole numbers, we can round this to the nearest whole number to get:
0.16 gallons ≈ 0.2 gallons
Hence, each chair or table requires between 0.2 and 1 gallon of paint to be painted.

Step-by-step explanation:
Note: the chapter summary can be found in chapter 22 of the Pearson Education,Inc. (PDF format).
In the chapter, a single slit aperture diffraction and a circle aperture diffraction was discussed.
A circle aperture diffraction occurs when light pass through a tiny hole or aperture to produce a circular disc image. This disc is called Airy's disc.
To calculate the aperture diameter,d we can use the formula below;
d= m× λ/ sin θ. ------------------------------------------------------------------------------(1).
The single slit aperture diffraction is when light pass through a single slit to produce. The wavelength, λ is greater than the width of the aperture.
