Step-by-step explanation:
The Downtown Community Barbecue served 404 dinners. A child's plate cost $2.80 and an adult's plate cost $6.90. A total of $1,963.50 was collected. How many of each type of plate was served? Round answers to the nearest whole person.
The number of childs plate are 201 and adult's plate are 203.
Let's use C to represent the number of child plates and A to represent the number of adult plates.
We know that a child's plate costs $2.80 and an adult's plate costs $6.90.
Therefore, we can write two equations based on the information given:
The total number of plates served is 404
C + A = 404 ...(1)
C=404-A
The total amount collected is $1,963.50
2.8C + 6.9A = 1963.5 ..(2)
2.8(404-A)+6.9A= 1963.5
1131.2 - 2.8A +6.9A=1963.5
4.1 A =1963.5 -1131.2
4.1A=832.3
Divide both sides by 4.1
A=832.3/4.1
A=203
Now put A in equation (1)
C+203=404
C=404-203
C=201
Hence, the number of childs plate are 201 and adult's plate are 203.

an octagonal prism has a surface area of 50mm^2 and a volume of 88 mm^3 Another octagonal prism has a surface area of 450mm^2 and a volume of 792mm^3. Are these two shapes similar ? Explain your answer
The two octagonal prisms are similar because their corresponding sides are proportional.
How do we determine the octagonal prisms are similar?We can find out if two octagonal prisms are similar by checking if they have the same shape but may be different sizes. Two shapes are similar if their corresponding sides are proportional, and their corresponding angles are congruent.
Let's represent the dimensions of octagonal prism1:
Base edge length = a
Height = h
The octagonal prism2 dimensions:
Base edge length = b
Height = k
From the surface area and volume equations of an octagonal prism, we have the following system of equations:
50 = 2a² + 8ah
88 = 2a²h
450 = 2b² + 8bk
792 = 2b²k
We can simplify these equations by dividing the second equation by the first, and the fourth equation by the third, to eliminate h and k:
88/50 = 2a²h / (2a² + 8ah) => 44/25 = h / (a + 2h)
792/450 = 2b²k / (2b² + 8bk) => 44/25 = k / (b + 2k)
Then, we rearrange the equations to obtain expressions for h and k in terms of a and b, respectively:
h = (44/25) * (a + 2h)
k = (44/25) * (b + 2k)
Multiplying both sides of each equation by 25/19, we obtain:
h = (44/19) * a
k = (44/19) * b
We can now check if the corresponding sides are proportional:
Base edge length = a:b = 1:3
Height = h:k = 1:3
Since the corresponding sides are proportional, the two octagonal prisms are similar.

Mitra drives her car 469.8 miles and uses 14.5 gallons of gasoline. Adira drives her car 355 miles and uses 12.5 gallons of gasoline. What is the difference between the gas mileage for Mitra's car (in miles per gallon) and the gas mileage for Adira's car (in miles per gallon)?
A) 2 miles per gallon
B) 4 miles per gallon
C) 8 miles per gallon
D) 9 miles per gallon
Answer:
4 miles per gallon. Answer choice B is correct.
Step-by-step explanation:
To find the gas mileage for each car, we need to divide the distance traveled by the amount of gasoline used.
For Mitra's car, the gas mileage is:
gas mileage = distance traveled / amount of gasoline used
gas mileage = 469.8 / 14.5
gas mileage = 32.4 miles per gallon
For Adira's car, the gas mileage is:
gas mileage = distance traveled / amount of gasoline used
gas mileage = 355 / 12.5
gas mileage = 28.4 miles per gallon
To find the difference in gas mileage, we can subtract the gas mileage for Adira's car from the gas mileage for Mitra's car:
difference = gas mileage for Mitra's car - gas mileage for Adira's car
difference = 32.4 - 28.4
difference = 4 miles per gallon
Therefore, the difference in gas mileage between the two cars is 4 miles per gallon. Answer choice B is correct.

The equation of the line that passes through the point (4, 2) and is perpendicular to the line y = 43x is y = (-1/43)x + (90/43).
What is the equation of a line that passes through the point ( 4 , 2 ) that is perpendicular to the line y = 43x?The formula for equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
Given that the line has a slope of 43.
To find the slope of the line perpendicular to it, we use the fact that the product of the slopes of two perpendicular lines is -1.
So, the slope of the perpendicular line is -1/43.
Using the point-slope form of a line, we can write the equation of the line as:
y - y1 = m(x - x1),
where (x1, y1) = (4, 2) and m = -1/43
Plugging in the values, we get:
y - 2 = (-1/43)(x - 4)
y - 2 = (-1/43)x + (4/43)
y = (-1/43)x + (4/43) + 2
y = (-1/43)x + (90/43)
Therefore, the equation of the line is y = (-1/43)x + (90/43).

Assume that the speed of automobiles on an expressway during rush hour is normally distributed with mean of 62 mph and a standard deviation of 5 mph.
What percent of cars are traveling slower than 62 mph?
Write your percentage as a decimal (so 12% = 0.12)!
The percentage of cars traveling slower than 62 mph during rush hour is 0.5 or 50%.
Since the speed of automobiles on an expressway during rush hour is normally distributed with a mean of 62 mph and a standard deviation of 5 mph, we can use the cumulative distribution function (CDF) of the normal distribution to find the percentage of cars traveling slower than 62 mph.
Let X be the speed of an automobile on the expressway during rush hour. Then, X follows a normal distribution with mean (µ) = 62 mph and standard deviation (σ) = 5 mph.
We want to find P(X < 62), which represents the probability that a car is traveling slower than 62 mph.
Using the standard normal distribution table or a calculator with built-in functions for the normal distribution, we can find the z-score corresponding to the value X = 62, using the formula;
z = (X - µ) / σ
Plugging in the given values;
z = (62 - 62) / 5 = 0
Now, we can find the cumulative distribution function (CDF) of the standard normal distribution at z = 0, denoted as Φ(0), which represents the probability that a standard normal random variable is less than or equal to 0.
Using the standard normal distribution table or a calculator with built-in functions for the normal distribution, we can find Φ(0) to be approximately 0.5.
So, P(X < 62) = Φ(0)
= 0.5
Therefore, the percentage of car is 0.5 or 50%

The probability that a randomly selected person in the region is a woman in the 18-24 age range living alone is approximately 0.14 or 14%.
To find the probability that a randomly selected person in the region is a woman in the 18-24 age range living alone, we need to look at the intersection of the "Female" row and the "0-24" age column in the table.
The probability of selecting a woman in the 18-24 age range living alone is:
P(woman, 18-24, living alone) = (Number of women in the 18-24 age range living alone) / (Total number of people living alone)
From the table, we can see that the number of women in the 18-24 age range living alone is 20.9. The total number of people living alone is 153.6.
P(woman, 18-24, living alone) = 20.9 / 153.6
