The diagram shows rectangles 1, 2, 3, and 4. WHICH ARE SIMILAR
The given rectangles 2 and 3 are similar.
What are similar figures?Similar figures mean when two figures are of the same shape but are of different sizes. In other words, two figures are called similar when they both have a lot of the same properties but still may not be identical.
From the rectangle 2 and 3,
18/40 = 36/80
9/20 = 9/20
So, figure 2 and 3 are similar

The z-values, standard deviations, and sample sizes that produce a margin of error of 0.95 is z = 2.14; s = 4; n = 81.
What is the margin of error?The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.
The formula of the margin of error is given by the formula,

Graph circles A and B in the coordinate plane. circle A with center at (0,0) and radius of 6,circle B with center at (-4,-2) and radius of 4.
A circle can be represented as an equation or on a graph
The equations of the circles are [tex]x^2 + y^2 = 36[/tex] and [tex](x + 4)^2 + (y + 2)^2 = 16[/tex]
How to graph the circlesThe equation of a circle is represented as:
[tex](x - a)^2 + (y - b)^2 =r^2[/tex]
Where:
Center = (a,b)
Radius = r
For circle A, we have the equation to be:
[tex](x - 0)^2 + (y - 0)^2 =6^2[/tex]
[tex]x^2 + y^2 = 36[/tex]
For circle B, we have the equation to be:
[tex](x + 4)^2 + (y + 2)^2 =4^2[/tex]
[tex](x + 4)^2 + (y + 2)^2 = 16[/tex]
Hence, the equations of the circles are [tex]x^2 + y^2 = 36[/tex] and [tex](x + 4)^2 + (y + 2)^2 = 16[/tex]

A merchant bought a table for ₹8250 and spent ₹175 on its transportation. He
sold the table for ₹7500. Find its gain or loss?
Answer: Loss of 925
==============================================
Work Shown:
Total cost = 8250+175 = 8425
Total revenue = 7500
Profit = revenue - cost = 7500 - 8425 = -925
Profit = -925
The negative profit means the merchant lost money.
Answer: The merchant lost 575 dollars or whatever you call them.
Step-by-step explanation:
7500+175=7675
8250-7675= 575

Question:
A party pack consists of x chocolate bars and x cans of drinks. Each chocolate bar costs $3 and each can of drink costs $1. The total cost for the chocolate bars and drinks in a party pack is more than $10. Find the minimum number of choclate bars in a party pack.
Btw, my teacher told me that the ans was 3. I'm kind of confused.
Answer:
3
Step-by-step explanation:
Your teacher is correct. The reason is because it is the total cost of both the chocolate and the can… if the choc is $3 and can is $1, you can have 3 chocolate bars because when you add the one can which is one dollar, it equals $10
3x3 = 9
9+1 = 10

The volume of this right prism is 240.5 ft³. What is the height, x, of the prism? Enter your answer as a decimal in the box.
Answer:
7.4 is the correct answer
Step-by-step explanation:
Height 'x' of the given right prism is 7.4 feet.
Volume of right prism:What information do we have?
Height of base = 5 ft
Length of first parallel line = 5 ft
Length of Second parallel line = 8 ft
Volume of prism = 240.5 ft³
Volume of prism = Area of base × height
Volume of prism = (1/2)(sum of parallel line)(Height) × height
240.5 = (1/2)(5+8)(5) × height
240.5 = (1/2)(13)(5) × height
240.5 = 32.5 × height
Height of prism = 7.4 feet
