For what values of x and y must ABCD be a parallelogram?
The values of x and y needs to be 39 degrees and 21 degrees respectively to show that ABCD is a parallelogram.
We know that opposite angles of a parallelogram are equal and we are asked to find the value of x and y.
We are given that angle A = 3y angle B = 3x , angle C = y + 78 and angle D = 4x - 21
Now as we know that the opposite angles are going to be equal.So,
angle A = angle C
3y = y + 78
2y = 78
y = 39
So, the value of y is going to be 39 degrees.
Similarly, we can also find the value of x.
angle B = angle D
3x = 4x - 21
-x = -21
x = 21
So, the value of x is going to be 21 degrees.
Hence, the values of x and y needs to be 39 degrees and 21 degrees respectively to show that ABCD is a parallelogram.

The ellipse with x-intercepts (2, 0) and (-2, 0); y-intercepts (0, 4) and (0, -4).
Answer:
[tex]\dfrac{x^2}{4}+\dfrac{y^2}{16}=1[/tex]
Step-by-step explanation:
If the ellipse has its x-intercepts at points (2, 0) and (-2, 0) and y-intercepts at points (0, 4) and (0, -4), then its symmetric across the y-axis and across the x-axis.
Moreover,
[tex]a=2\\ \\b=4[/tex]
The equation of such ellipse is
[tex]\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1[/tex]
Hence, the equation of the ellipse is
[tex]\dfrac{x^2}{2^2}+\dfrac{y^2}{4^2}=1\\ \\ \\\dfrac{x^2}{4}+\dfrac{y^2}{16}=1[/tex]

You put $400 in an account. The account earns $18.00 simple interest in 9 months. What is the annual interest rate
Answer:$18.00
Step-by-step explanation:
A gardener is planting two types of trees:
Type A is 7 feet tall and grows at a rate of 2 inches per year.
Type B is 5 feet tall and grows at a rate of 6 inches per year.
Algebraically determine exactly how many years it will take for these trees to be the same height.
It will take 6 years for the trees to be same height.
Step-by-step explanation:
Given,
Initial height of Type A = 7 feet = 7*12 = 84 inches
Growth rate = 2 inches per year
Let,
x be the number of years
Total height = T
T = 2x+84 Eqn 1
Initial height of Type B = 5 feet = 5*12 = 60 inches
Growth rate = 6 inches per year
T = 6x+60 Eqn 2
For same height;
Eqn 1 = Eqn 2
[tex]2x+84=6x+60\\84-60=6x-2x\\24=4x\\4x=24[/tex]
Dividing both sides by 4
[tex]\frac{4x}{4}=\frac{24}{4}\\x=6[/tex]
It will take 6 years for the trees to be same height.

A) y= 2x. Y is double x.
B) y= 3x. Y is triple x.
C) y= 2x + 1. Y is twice x plus 1.
D) y= 2x -1. Y is twice x minus 1.
The function that correctly represents the pattern in the given table is y = 2x + 1, which means that, for each input X, you multiply by 2 and then add 1 to obtain output Y.
Explanation:The table of values given indicates a linear relationship between X and Y. If we look closely, we can see that for every unit increase in X, Y increases by 2 units. This pattern indicates that the function is characterized by the equation y = 2x + 1.
So, the correct answer is C) y = 2x + 1. This means that Y is twice the value of X plus 1. In simpler terms, we multiply the input variable (X) by 2 and then add 1 to determine the output (Y).
None of the other given function expressions correctly describe the pattern observed in the table.

the 2619 women students on a campus constitute 54% of the entire student body. what is the total enrollment of the college?
Answer:
4850 students
Step-by-step explanation:
if 2619 women make up 54% of the entire student body, then we know that 0.54x=2619, since 54%=0.54 and we can call x the entire student body. solve:
0.54x=2619
÷0.54 ÷0.54
x=4850
henceforth, the total enrollment is 4850 students.
hope this is helpful!
Answer:
4850 students
Step-by-step explanation:
Let b = total enrollment.
Then 54% of b = 2619. Find b by dividing both sides of
0.54b = 2619 by 0.54:
b = 4850
The total enrollment is 4850.

What is the least number of years until the year rounded to the nearest ten is 2060
Answer:
35
Step-by-step explanation:
Final answer:
To determine the least number of years from 2023 until the year rounds to 2060, subtract 2023 from 2055, the first year that rounds to 2060, resulting in 32 years.
Explanation:
The question is asking for the least number of years it will take for the current year to be rounded to nearest ten to become 2060. To answer this, we consider the year closest to 2060 that when rounded will result in exactly 2060. We are considering that the current year is 2023, optimizing the rounding rule of being closer to or equal to the next multiple of ten (2055-2064 would round to 2060). Following this logic, the first year that rounds to 2060 is 2055, therefore the least number of years from 2023 until we reach a year that rounds to 2060 is 2055 minus 2023, which is 32 years.

Step-by-step explanation:
What is mZS?
Enter your answer in the box
Next
m∠S = 45°
Solution:
Given ∠R = 3x°, ∠S = 2x°, ∠T = 3x°.
Sum of the angles of a triangle = 180°
⇒ m∠R + m∠T + m∠S = 180°
⇒ 3x° + 3x° + 2x° = 180°
Adding all the angles.
⇒ 8x° = 180°
Divide both sides of the equation by 8, we get
⇒ x° = 22.5°
Substitute x = 22.5° in m∠S.
⇒ m∠S = 2 × 22.5°
⇒ m∠S = 45°
Hence, m∠S = 45°.

4x=18
x=4.5
Answer:
4.5
Step-by-step explanation:
Since its an equilateral triangle, all the sides are equal.
SO, you can set up the equation:
3 ( 4x + 3 ) = 63
Start by disributing
12x + 9 =63
Subtract 9 from each side to isolate the variable
12x = 54
Divide both sides by 12
x = 4.5
why 2+2=4 and not 2+2=22 ?
2 + 2 = 4 because 4 is a sum of 1-digit numbers
2 + 2 ≠ 22 because 22 is the sum of 1-digit and 2-digit numbers
Step-by-step explanation:
Lets explain some important notes:
The 1-digit number consists of one digit, 4 is a one-digit numberThe 2-digit number consists of two digits, ones digit and tens digit, 23 is a 2-digit number, the ones digit is 3 and the tens digit is 2, so its value is 20 + 3The 3-digit number consists of ones digit, tens digit and the hundreds digit, 123 is a 3-digit number, the ones digit is 3, the tens digit is 2 and the hundreds digit is 1, so its value is 100 + 20 + 3∵ 2 + 2 is the addition problem of two 1-digit numbers
∴ There sum will be 4 which is also 1-digit number
∴ 2 + 2 must be 4
∵ 22 is a two digit number
∴ Its value is 20 + 2 ⇒ not 2 + 2
∴ 2 + 2 can not be 22
2 + 2 = 4 because 4 is a sum of 1-digit numbers
2 + 2 ≠ 22 because 22 is the sum of 1-digit and 2-digit numbers

Describe the relationship between the 5 in 11.205 and the 5 in 5.32. Write 2 different statements using "times the value.
Final answer:
The 5 in 11.205 is in the thousandths place and represents 0.005, while the 5 in 5.32 is in the units place, representing 5. The 5 in 5.32 is one thousand times the value of the 5 in 11.205, and vice versa.
Explanation:
The relationship between the 5 in 11.205 and the 5 in 5.32 can be described in terms of their place values. In the number 11.205, the 5 is in the thousandths place, which means it represents 5 thousandths or 0.005. In the number 5.32, the 5 is in the units place, which means it represents 5 ones or simply 5.
To compare their values, we can say that the 5 in 5.32 is one thousand times the value of the 5 in 11.205 because 5 divided by 0.005 equals 1000. Alternatively, we could say the 5 in 11.205 is one thousandth the value of the 5 in 5.32.
These comparisons are based on the understanding of place value in decimal numbers, where each position to the left or right of the decimal point represents a power of 10. Therefore, the value of a digit is determined by its position relative to the decimal point.
Explicit equation for the nth term of the geometric sequence 3584,896,224,

Solution:
Given that we have to find the explicit equation for nth term of geometric sequence
Given sequence is:
3584, 896, 224
A geometric sequence has a common ratio
Let us find the common ratio. Divide each term by the previous term.
[tex]r=\frac{896}{3584} = 0.25\\\\r = \frac{224}{896} = 0.25[/tex]
Thus the common ratio is 0.25
The formula for nth term of geometric sequence is given as:
[tex]a_n=ar^{n-1}[/tex]
Where,
[tex]a_n[/tex] is the nth term of sequence
a is the first term of sequence
r is the common ratio
Here in given sequence 3584, 896, 224
first term = a = 3584
common ratio = r = 0.25
Therefore,
[tex]a_n=3584(0.25)^{n-1}[/tex]
[tex]\text{Where } n\geq 1 \text{ ,n = 1, 2, 3, 4, .........}[/tex]
"n" is a natural positive number greater than or equal to 1
Thus the explicit equation to find nth term is found

What is the cube root of 27x18?
Final answer:
The cube root of 27x18 is 3x6, determined by taking the cube root of each term, with 27 yielding 3 and the x18 exponent reduced by a factor of 3 to x6.
Explanation:
The question posed is, "What is the cube root of 27x18?" To solve this, we need to break down the expression and compute the cube root of both terms separately. The cube root of 27 is 3 because 33 = 27. For the variable x raised to the 18th power, taking the cube root means we divide the exponent by 3, which gives us x6. Therefore, the cube root of 27x18 is 3x6.
