Mrs. Hanger is painting the following picture of an H to hang in the entryway of her home. She has made the following scale drawing as her model. The scale used on the drawing is 1:6.
As you can see, the "H" is going to be painted brick red in the center of a rectangular beige background. This means the distance from the "H" to the top of the picture will be the same as the distance from the "H" to the bottom of the picture. Similarly, the distance from the "H" to the left side of the picture will be the same as the distance from the "H" to the right side of the picture. Finally, each segment of the "H" will have the same width.
Mrs. Hanger decides to change the scale of her drawing from 1:6 to 1:4.
Is the new scale drawing larger or smaller than the original scale drawing? Use complete sentences to explain your reasoning.
What are the dimensions of the painting on the new scale drawing?
If the scale of her drawing is changed from 1:6 to 1:4, the new scale will be larger than the original scale as 1 unit is represented by 4 inches.
How to interpret Scale drawing?To find the area of the hanger H, we will need to split the H into different rectangular parts and find their area, after which we add all the numbers up together.
The total area of H = 60 in. + 18 in. + 60 in.
Total Area of H = 138 in.²
The total area of the entire rectangular figure is 720 in.² Thus;
The total area of the beige colored area is; 720 in.² - 138 in.² = 582 in.²
Total area of the beige area is 582 in.²
The percentage of 582 in.² out of 720 in.² is;
582 in.²/720 in.² = 80.83 %
Thus, 80.83% of the entire rectangular figure will be beige colored.
Now, if the scale of her drawing is changed from 1:6 to 1:4, the new scale will be larger than the original scale as 1 unit is represented by 4 inches.
Dimensions of the new scale drawing = 5(3/2) = 7.5 inches by 4(3/2) = 6 inches

1 studies Biology but not Art.
7 study neither subject.
Given that a randomly selected student studies Art, what is the probability the student studies Art and Biology?
Answer:
1/12Step-by-step explanation:
Total number is 20.
Distribution is:
Art + Biology = 1Biology = 1Neither = 7The rest = 20 - 9 = 11, the Art students
Total number of Art students becomes 12

At a local ballpark a team charges $10 per ticket the team must pay its players $4000 it costs the owner $6 for each souvenir they gave away how many tickets must be sold to break even
Answer:400
Step-by-step explanation:it didn’t say it gives away and souvenirs so the 6$ can be out the equation and 4000 divided by 10 is 400
The number of tickets that must be sold to break even is 1000 if at a local ballpark a team charges $10 per ticket the team must pay its players $4000.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The question is incomplete.
The complete question is:
At a local ballpark, a team charges $10 per ticket. The team must pay its players $4000. It costs the owners $6 for each souvenir they give away.
How many tickets must be sold to break even.
Let x be the number of tickets.
Let y be the total cost
From the data given in the question we can frame the linear equation in two variables:
y = 6x + 4000
y = 10x
After solving the above two linear equations in two variables.
6x + 4000 = 10x
10x - 6x = 4000
4x = 4000
x = 1000
Thus, the number of tickets that must be sold to break even is 1000 if at a local ballpark a team charges $10 per ticket the team must pay its players $4000.

Six men can paint a building in 15 days. Find the number of days taken for 5 men to paint the same building.??
please
Answer:
18
Step-by-step explanation:
1) if 6 men in 15 days, then 1 man will spent 15*6=90 days to paint the building;
2) if it takes 90 days 1 man, then for 5 men it takes 90/5=18 days.
The number of days for 5 men to paint the building is given by the proportion A = 18 days
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
The number of days for 6 men to paint a building is = 15 days
And , the number of days for 5 men to paint the building is A
Now , the inverse proportion is
15 x 6 = 5 x A
Divide by 5 on both sides , we get
A = ( 15 x 6 ) / 5
A = 3 x 6
A = 18 days
Hence , the number of days to paint is 18 days

The _______ pair is the location of a point on the coordinate plane and contains the
x coordinate and y coordinate
Answer:
Ordered
Step-by-step explanation:
The ordered pair is the location of a point on the coordinate plane and contains the x coordinate and y coordinate
An ordered pair tells you the location of a point by relating the point's location along the x-axis (the first value of the ordered pair) and along the y-axis (the second value of the ordered pair). In an ordered pair, such as (x, y), the first value is called the x-coordinate and the second value is the y-coordinate.
