Rectangle ABCD is congruent to rectangle HGJK.
Rectangles A B C D and H G J K are shown. The length of A B is 11 inches. The length of K H is 18 inches.
What is the area of rectangle ABCD?
square inches
Answer:
It is 198
Step-by-step explanation:
(Width)(Height)
mutliply (11) times (18)
The area of rectangle ABCD is 198 square inches
The given parameters are:
[tex]\mathbf{AB = 11}[/tex]
[tex]\mathbf{KH = 18}[/tex]
Because the rectangles are congruent, then:
[tex]\mathbf{HG = AB = 11}[/tex]
[tex]\mathbf{KH = DA= 18}[/tex]
So, the area of rectangle ABCD is the product of side lengths AB and DA
So, we have:
[tex]\mathbf{Area = AB \times DA}[/tex]
Substitute values for AB and DA
[tex]\mathbf{Area = 11 \times 18}[/tex]
[tex]\mathbf{Area = 198}[/tex]
Hence, the area of rectangle ABCD is 198 square inches

Why are arithmetic sequences discrete data?
Answer:
If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.
Step-by-step explanation:
Answer:
A sequence is a discrete structure used to represent an ordered list.
Step-by-step explanation:
Discrete values are values between the terms if the sequences are not included in the sequence. If you collect all the terms of the sequence into a set, that set will always be discrete, because there's only countably many of them, and every interval is uncountable. So in that sense, yes, sequences are discrete. A sequence is a discrete structure used to represent an ordered list. A sequence is a function from a subset of the set of integers (usually either the set {0,1,2,. . .} or {1,2, 3,. . .}to a set S. We use the notation an to denote the image of the integer n. We call an a term of the sequence.

How long will it take an investment to double in value if the interest rate is 6% compounded continuously
Answer:
11.55 years
Step-by-step explanation:
Formula to calculate the final value when the money is compounded continuously is,
Final value = [tex]\text{(Present value)}.e^{rt}[/tex]
Here 'r' = rate of interest
t = duration for the investment
Let the money invested = $x
We have to find the duration in which the present value gets doubled.
Final value = $2x
Rate of interest = 6% per year ≈ 0.06
By substituting these values in the formula,
[tex]2x=x.e^{0.06t}[/tex]
[tex]2=e^{0.06t}[/tex]
ln(2) = [tex]\text{ln}e^{0.06t}[/tex]
0.693147 = 0.06t
t = 11.55 years
Therefore, invested amount will be doubled in 11.55 years.

Answer:
72°
Step-by-step explanation:
Vertical angles are congruent.
m∠3 = m∠4
7x + 2 = 5x + 22
2x = 20
x = 10
m∠3 = m∠4 = 72°
Identify and write the hypothesis and the conclusion of the following conditional statement. "If I am running, then I am not awake."
Answers:
Hypothesis = "I am running"
Conclusion = "I am not awake"
===================================
Explanation:
All conditional statements are in the form "If P, then Q" where P and Q are placeholders for the hypothesis and conclusion respectively.
So you can say the basic format of a conditional is "If hypothesis, then conclusion".

Q1
|a-b| = b-a when a<b
Q2
104159/33000
Step-by-step explanation:
Q1
If a<b then a-b will always be negative. To get the absolute value, we can take -(a-b) = -a+b = b-a.
Q2
Let x = 3.12789789789...
We isolate the repeating decimal to start after the decimal, so we multiply by 100.
100x = 312.789789789...
We want to multiply by 10 for each digit that repeats (in this case 3), to get the repeating part to the left of the decimal.
100000x = 312789.789789
Subtracting the two...
x(100000-100) = 312789.789789 - 312.789789
99900x = 312477
x = 312477/99000 = 104159/33000

choose the letter that corresponds to the correct answer
Answer:
A
Step-by-step explanation:
Determine if the following argument always applies, sometimes applies, or never applies. Provide at least 2 examples in your explanation.
"The sum of a number and its opposite is always 1."
Answer:
Never applies
Step-by-step explanation:
Given
Argument: The sum of a number and its opposite is always 1
Assume a positive number x
The opposite of the number is negative x (i.e. -x)
The sum of both numbers is:
[tex]Sum = x + (-x)[/tex]
Open Bracket
[tex]Sum = x -x[/tex]
[tex]Sum = 0[/tex]
Now, take for instance.
[tex]Number = 5[/tex]
Opposite would be
[tex]Opposite = -5[/tex]
Their sum is:
[tex]Sum = 5 + (-5)[/tex]
[tex]Sum = 5 -5[/tex]
[tex]Sum = 0[/tex]
Another instance is:
[tex]Number = -8[/tex]
Opposite would be
[tex]Opposite = 8[/tex]
Their sum is;
[tex]Sum = -8 + 8[/tex]
[tex]Sum = -0[/tex]
Hence, the argument never applies because the sum is never 1
