Answer:
Building's actual height 32 meters
Building's shadow height 20 meters
Person's shadow height 1.2 meters
Person's actual height = ?
Find the person's actual height:
This is a proportion problem.
Actual height to shadow height
Building = Person
32 : 20 = x : 1.2
32 * 1.2 = 20 * x
38.4 = 20x
38.4/20 = 20x/20
1.92 = x
The person's actual height is 1.92 meters long.
32 : 20 = 1.92 : 1.2
32/20 = 1.60
1.92/1.2 = 1.60

A restaurant has a sign by the front door that says, "Maximum occupancy: 75 people." Answer each question and explain or show your reasoning.
What percentage of its capacity is 9 people?
What percentage of its capacity is 51 people?
What percentage of its capacity is 84 people?
Step-by-step explanation:
9/75 * 100% =
51/75 * 100% =
84 /75 * 100% =
The percentage of its capacity is 9 people, 51 people, and 84 will be 12%, 68%, and 112%, respectively.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
A restaurant's front entrance is marked with the words "Maximum occupancy: 75 persons."
The percentage of its capacity is 9 people is given as,
P = (9/75) x 100
P = 12%
The number of people is less than the maximum capacity.
The percentage of its capacity is 51 people is given as,
P = (51/75) x 100
P = 68%
The number of people is less than the maximum capacity.
The percentage of its capacity is 84 people is given as,
P = (84/75) x 100
P = 112%
The number of people is more than the maximum capacity.

Harper knows he is 50 yards from school. The map on his phone shows that the school is 2/3 inch from his current location. How far is Harper from home, if the map shows the distance as 3 inches?
Actual distance of the Harper from the school = 50 yards.
According to map the distance from the school = 34 inch.
We could say 34 inches represents 50 yards.
So, 1 inches could be represented by 50/34 = 25/17 yards.
In order to find the actual length of 3 inches in yards, we need to multiply 1 inches value of yards by 3.
Therefore, 3 inches = 3* 25/17 = 75/17 = 4 7/17 yeards in decimals 4.412 yards approximately.
Therefore, Harper from home is 4 7/17 yeards or 4.412 yards approximately if the map shows the distance as 3 inches.
Answer:
Actual distance of the Harper from the school = 50 yards.
According to map the distance from the school = 34 inch.

For each pair of points, find the slope of the line that passes through both points. If you get stuck, try plotting the points on graph paper and drawing the line through them with a ruler.
Answer: The answer is number choice 1.
Step-by-step explanation:
The slope of each pair of coordinates are as follows -
Pair 1 → (1, 1) and (7, 5) → m[1] = 2/3
Pair 2 → (1, 1) and (5, 7) → m[2] = 3/2
Pair 3 → (2, 5) and (-1, 2) → m[3] = 1
Pair 4 → (2, 5) and (-7, -4) → m[4] = 1
What is Slope of a line?Slope of a line is defined as the rate of change of dependent variable with respect to independent one.
Given are the four pairs of coordinates.
The formula to calculate the slope of a line using the coordinates is -
m = (y₂ - y₁) / (x₂ - x₁)
→ for (1, 1) and (7, 5), the slope will be -
m[1] = (5 - 1)/(7 - 1)
m[1] = 4/6
m[1] = 2/3
→ for (1, 1) and (5, 7), the slope will be -
m[2] = (7 - 1)/(5 - 1)
m[2] = 6/4
m[2] = 3/2
→ for (2, 5) and (-1, 2), the slope will be -
m[3] = (2 - 5)/(-1 - 2)
m[3] = -3/-3
m[3] = 1
→ for (2, 5) and (-7, -4), the slope will be -
m[4] = (- 4 - 5)/(-7 - 2)
m[4] = -9/-9
m[4] = 1
Therefore, we can write the slope of each pair of coordinates as -
Pair 1 → (1, 1) and (7, 5) → m[1] = 2/3
Pair 2 → (1, 1) and (5, 7) → m[2] = 3/2
Pair 3 → (2, 5) and (-1, 2) → m[3] = 1
Pair 4 → (2, 5) and (-7, -4) → m[4] = 1

What is the length of side AC of the triangle? Pls hurry
Answer:
Step-by-step explanation:
According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that you cannot draw a triangle that has side lengths 2, 7 and 12, for instance, since 2 + 7 is less than 12.
If one inch represents 12 feet, what dimensions would you use to make a scale drawing of a building 75 feet by 80 feet.????
Answer:
6.25 inch by 20/3 inch (6.67 inch).
Step-by-step explanation:
Answer:
1 inch = 12 feet
length of the drawing building=75 feet
12 feet = 1 inch
75 feet= 75 / 12
=6.25 inches
Breadth of drawing building= 80 feet
12 feet=1 inch
80 feet= 80/12

The history museum is hosting a special exhibition on history of flight. The admission ticket for each adult costs $3 and the admission ticket for each child costs $2. On the opening day of the exhibition, 60 tickets were sold for a total of $160. How many adults visited the special exhibition?
Use simultaneous equation for this problem
y= number of adults
x = number of children
3y + 2x = 160
y + x = 60
then we double the second equation
3y + 2x = 160
2y + 2x = 120
we cancel x by elimination
3y - 2y = 160 - 120
y = 40
40 adults visited the special exhibition at the museum
Let x represent the number of admission ticket for adult and y represent the number of admission ticket for child.
60 tickets were sold for a total of $160. Hence:
x + y = 60 (1)
3x + 2y = 160 (2)
Solving equations 1 and 2 simultaneously gives:
x = 40, y = 20
Therefore 40 adults visited the special exhibition at the museum.
