There are 72% of apartments in the building are small.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
The ratio of small apartments to regular apartments is 18 to 7.
Now,
Since, The ratio of small apartments to regular apartments is 18 to 7.
⇒ S : R = 18 : 7
Hence, The percent of small building is find as;
⇒ Percent = S / (S + R) × 100
⇒ Percent = 18 / (18 + 7) × 100
⇒ Percent = 18 / 25 × 100
⇒ Percent = 18 × 4
⇒ Percent = 72%
Thus, There are 72% of apartments in the building are small.

Answer:
To show that a reflected object is congruent to its preimage, follow these steps:
Identify the line of reflection.
Locate corresponding points on the preimage and its reflection.
Measure the distances between the line of reflection and the corresponding points.
Compare the distances for each corresponding point.
If the distances are equal, the reflected object is congruent to the preimage.
Step-by-step explanation:
Step-by-step explanation:
To show that a reflected object is congruent to its preimage, you need to demonstrate that the reflected object and the preimage have the same size and shape. Here's how you can do it:
1. Identify the preimage
2. Determine the line of reflection
3. Reflect the preimage
4. Compare corresponding points
5. Check angles

In a simpler terms a rational number can be represented as a / b where b is not equal to zero.
Example of rational numbers are 48, 10, 4, √4, √16 etc.
Irrational numbers are real numbers that cannot be expressed as a ratio of integers; example of irrational numbers are √2, √5.
Therefore, m is a rational integer. Hence, m = -7.

Help. Where do I put the dot, should it be opened or closed, and what direction should the line face?
Answer: 5 with an open circle facing the right.
Step-by-step explanation:
First: you need to know the difference between closed and open circles. Closed means less than or equal to/ greater than or equal to while an open circle just means less than/ greater than.
Second: To know if it will be facing left or right is very simple. It is just if the number is increasing or decreasing in your problem. If increasing it goes right if decreasing it goes left. In this case, the number increases each day so it will face the right.
Third: To start the problem you subtract the number of shells she has already (34) by how many she needs (100) which is 66. then divide 66 by the number of seashells they get a day (12) which would give you 5.5
Fourth: I'm going to guess that you can't do decimals on the graph so all you have to do is put an open circle with the arrow facing the right meaning everything after this point, not including the number it is on.
Answer:
d ≥ 7
Step-by-step explanation:
A closed dot means you CAN use the number in the equality (greater than and equal to or less than and equal to). An OPEN dot means it's just greater than or less than, no equal to. Positive numbers GROW to the right so if the line is going that way it means greater than or greater than and equal to. The same is true for the left side. The left side makes numbers get SMALLER which means less than or less than and equal to. Your problem has a closed dot and an arrow to the right so the inequality is d ≥ 7.

If the room has a square area of 16 square meters and the rug is placed in the middle of the room, how much space would there be between each side of the rug and the wall?
Answer
the space would unknow between each side of the rug and the wall
Step-by-step explanation:
because we don't know how big the room is and what the shape of the room is we have no idea what the answer will be it could be a little less than the distance around the world or it could be no distance cause it is the same size as the room
(also the rug is in the middle of the the room)

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equation is given below.
C = 25 + 0.40 m
Where 'm' is the number of miles and 'C' is the total cost.
The number 0.40 represents the cost per mile and the number 25 represents the initial cost.
Thus, the correct option is C.

The difference of the given expression is 5x/12 - 5.
The given expressions are (3/4 x-1) and (1/3 x+4).
What is the subtraction of expressions?To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.
Here, (3/4 x-1) - (1/3 x+4)
= 3/4 x -1 -1/3 x -4
= (3/4 x - 1/3 x) -1-4
= 9/12 x - 4/12 x) - 5
= (9-4)/12 x - 5

FOR # 13-#14: As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100.
13. Write the inequality and solve the inequality for the number of sales you need to make.
14. Graph your inequality from #13 on a number line.
15. For n(34-n) <111, check whether n = -3 is a solution.
SOLUTION? (Yes or No)______
Answer:
13) x ≥ 50/3
14) see attached graph
15) Yes
Step-by-step explanation:
The equation relating the number of sales and pay is given by
y = 50 + 3x where x is the number of sales.
Q 13
If you need your pay to be exactly 100 then the above equation translates to 50 + 3x = 100
If you want the sales to be at least 100 then the above equation becomes an inequality 50 + 3x ≥ 100
We can re-write this as x ≥ 50/3
Q 14
See attached graph
x = 50/3 is a vertical line passing intersecting the x axis at x = 50/3(16.67)
All values of x ≥ 16.67 forms the region for the inequality
Q 15
Substitute -3 for n in the equation n(34-n) and check whether it satisfies the inequality
(-3)(34 - (-3)) = (-3)(37) is a negative number. (You don't actually have to calculate it but it works out to -111. ) Therefore it satisfies the inequality
n(n-34) < 111 Answer: YES

13. x ≥ 50/3
14. attached graph
15. Yes
