A toy company is building dollhouse furniture. A rectangular door of a dollhouse has a height of 7 centimeters and a width of 3 centimeters. What is the perimeter of the door on a scale drawing that uses the scale 3:5?
33 cm
20 cm
14 cm
12 cm
I will give brainiest and thanks if answer is right.
Answer:
12 cm
Step-by-step explanation:
In the picture
Answer: 33cm
Step-by-step explanation:
To find the perimeter of the door on the scale drawing, we first need to determine the dimensions of the door on the scale drawing.
The scale given is 3:5, which means that every 3 centimeters in real life corresponds to 5 centimeters on the scale drawing.
To find the height of the door on the scale drawing, we multiply the real-life height of 7 centimeters by the scale factor:
7 cm * (5 cm/3 cm) = 35/3 cm ≈ 11.67 cm
To find the width of the door on the scale drawing, we multiply the real-life width of 3 centimeters by the scale factor:
3 cm * (5 cm/3 cm) = 5 cm
Now that we have the dimensions of the door on the scale drawing (height: 11.67 cm and width: 5 cm), we can calculate the perimeter.
The perimeter of a rectangle is found by adding up all the sides. In this case, we have two sides of length 11.67 cm (height) and two sides of length 5 cm (width).
Perimeter = 2 * (11.67 cm) + 2 * (5 cm) = 23.34 cm + 10 cm = 33.34 cm
Therefore, the perimeter of the door on the scale drawing is approximately 33.34 cm.
Since the answer choices are given in whole numbers, the closest option to the calculated perimeter is 33 cm.

Answer:
angle FDE = 44 degrees
angle DEF = 66 degrees
angle FHG = 44 degrees
angle CDE = 63 degrees
angle BCE = 105 degrees
Step-by-step explanation:
first image
2x + 3x = 110
5x = 110
x = 22
angle FDE = 2x = 2(22) = 44
angle DEF = 3x = 3(22) = 66
angle FHG = 2x = y = 44
second image
2x - 21 + 42 = 3x - 21
42 = x
angle BCE = 3x - 21 = 3(42) - 21 = 105
angle CDE = 3y = 2x - 21 = 2(42) - 21 = 63

Answer:
Step-by-step explanation:
divide by 6
2k+8=-8
subtract 8 in both sides
2k=-16
divide by 2
k=-8
equal to -8
In order to solve for k you always want to try and isolate the variable (trying to get only k on one side of the equal sign). You can start of by distributing 6 into the numbers in the parenthesis. So 6 times 2k is 12k and 6 times 8 is 48. So in reality, you now have 12k+48= -48. Then you can subtract 48 from the left side to cancel it out. Note: you would not add 48 to cancel out the -48 on the right because you need a number on both sides of the equal sign. So once you subtract -48 from one side you must do it to the other so -48-48 is -96. Now you have 12k=-96. All you have to do now is cancel out the 12k but dividing since it is the inverse of multiplying. Divide 12 from both sides and -96 divided by 12 is -8.
So your answer is k=-8
You must read 130 pages for homework. Reading at the same rate as the previous question, can you complete the assignment in two hours?
Answer:
Since you must read 52 page per hour, and there is 2 hours to complete assignment, then you will do this:
52 + 52 = 104
You would be able to read 104 pages in 2 hours, which is less than 130, so you would NOT be able to complete the assignment.

Answer: x = 10
Step-by-step explanation:
Let's say that the unknown is x.
{2/5 = ?/25}
Step 1. 2/5 = x/25
Step 2. Multiply by 25 on both sides. 2/(5 * 25) = x/(25 * 25)
Step 3. 2 * 5 = x
Step 4. 10 = x
Step 5. Let's check the answer x; 2/5 = 10/25
Step 6. Simplify; 2/5 = (10/5) / (25/5)
Step 7. Check; 2/5 = 2/5
This answer is true

(1) The mean absolute deviation for the given data set is 18.
The mean absolute deviation (MAD) is a way of measuring of data variability that is defined as the average of each data point's absolute deviation from the mean. To calculate the MAD, first compute the mean of the data set, then subtract each data point from the mean and calculate the absolute value of the result.
Here is the step-by-step process for finding the MAD for the given data set:
Find the mean of the data set: (108 + 53 + 47 + 22 + 56 + 62) / 6 = 56
Subtract the mean from each data point:
108 - 56 = 52
53 - 56 = -3
47 - 56 = -9
22 - 56 = -34
56 - 56 = 0
62 - 56 = 6
Take the absolute value of each result:
|52| = 52
|-3| = 3
|-9| = 9
|-34| = 34
|0| = 0
|6| = 6
Find the average of the absolute deviations: (52 + 3 + 9 + 34 + 0 + 6) / 6 = 18
So, the mean absolute deviation for the given data set is 18.
(2) The mean absolute deviation for the given data set is 2.7
Find the mean of the data set: ( 12.2 + 6.8 + 3.4 + 8.8 ) /4 = 7.8
Subtract the mean from each data point:
12.2 - 7.8 = 5.4
6.8 - 7.8 = - 1
3.4 - 7.8 = - 4.4
8.8 - 7.8 = 1
Take the absolute value of each result:
|4.4| = 5.4
|-1| = 1
|-4.4| = 4.4
|1| = 1
Find the average of the absolute deviations: (5.4+ 1 + 4.4 + 1) / 4 = 2.95
So, the mean absolute deviation for the given data set is 2.95.

Answers for pictures 1, 2, &3
Question 1: P = 35 degrees
It is given to us that angles N and P are complementary.
Complementary angles means the sum of the angles = 90 degrees.
Because angles N and M are supplementary, meaning they = 180 degrees, you can subtract angle M from 180.
180 - M = N
180 - 125 = 55
N = 55 degrees
Now that we know N = 55 degrees, we subtract that from 90 degrees to find P for N + P = 90 degrees, so if we subtract 55 from 90 we will get the value of angle P.
90 - N = P
90 - 55 = 35
P = 35 degrees!
Question 2: Option 4
We are trying to figure out which angles are congruent to one another.
We can rule out option one, for angles 1 & 4 are supplementary meaning their sum = 180 degrees.
The same applies for options 2 & 3, leaving us with the correct answer, option 4. We can make sure this is true because angles 3 & 5 are alternate interior angles, and alternate interior angles of parallel lines are congruent.
Question 3: x = 5
The three different angles add up to 180 because they are a straight angle.
First, we need to find out what 9 and 10 are equal to.
To do so, we can subtract 85 from 180.
180 - 85 = 9x + 10x
9x + 10x = 95
Now that we have an equation, we can simplify to find the value of x.
9x + 10 = 95
19x = 95
Divide by 19 on each side to isolate the variable x
x = 5

Answer:
The required height of the lighthouse is given as 160 ft tall.
Given that,
A scale model of a lighthouse has a scale of 1 in. : 8 ft. The scale model is 20 inches tall.
What is the scale factor?
The scale factor is defined as the ratio of the modified change in length to the original length.
What is the Ratio?
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
here,
scale factor = 1 / 8 in per ft
Now,
The actual length of the lighthouse = 20 / [1 / 8]
= 20 × 8 = 160 ft
Thus, the required height of the lighthouse is given as 160 ft tall.
