If you were to make a quadrilateral by rotating triangle RST 180 degrees about U, a Rhombus would form.
A Rhombus is a type of quadrilateral that is defined by its unique properties. The most distinctive characteristic of a Rhombus is the presence of two pairs of congruent and adjacent sides. These sides create a symmetrical figure that is easily recognizable. The other key property of a Rhombus is the presence of two pairs of equal, opposite angles. When a triangle, such as RST, is rotated 180 degrees about a central point, such as U, it creates a Rhombus. The sides of the triangle become the sides of the Rhombus, while the rotation creates the diagonal lines that connect the vertices. This rotation also ensures that the Rhombus has the desired properties of two pairs of congruent sides and two pairs of equal, opposite angles.

PLSSS HELPP ASAP LAST QUESTION ****** An employee is 25 years old and starting a Roth IRA. The employee plans to invest $200 per month with an expected interest rate of 2.85%, compounded monthly. After 30 years of working, the employee wants to have $150,000 in the retirement account. What is the difference between the actual balance and the employee's goal?
A spreadsheet was used to calculate the correct answer. Your answer may vary slightly depending on the technology used.
The actual balance is $34,600.86 higher than the goal.
The actual balance is $34,600.86 lower than the goal.
The actual balance is $36,400.68 higher than the goal.
The actual balance is $36,400.68 lower than the goal.
The actual balance is $36,400.68 which lower than the goal of $150,000. The Option D is correct.
How do we derive the difference between the actual balance and the employee's goal?The Formula to use to derive the actual balance is: P[((1 + r/n)^(n*t)) - 1) / (r/n)] where: FV = future value, P = monthly deposits, r = interest rate, t = time in years, n = number of compound in a year
From the given:
P = 200
r = 2.85% 0.0285
t = 30 years
n = 12 (compounded monthly)
Future value = 200((1 + 0.0285/12)^(12(30)) - 1) / (0.0285 / 12)
Future value = $113,599.32
The difference between the actual balance and the employee's goal is:
= $150,000 - $113,599.32
= $36,400.86

Find the coordinate of the point P that divides each directed line segment in the given ratio. Round the
coordinate to the nearest tenth if necessary.
from K to L; 1 to 5
The coordinate of point P is
The direction of point P is (2.5, 3.3). In this way, the point P that separates the line fragment from K to L with a 1 to 5 proportion has the coordinate (2.5, 3.3).
Given a line segment from K to L, and the proportion of the division as 1 to 5, we can find the direction of point P that separates the line section into the predetermined proportion.
The direction of point P can be tracked down utilizing the accompanying recipe:
P = (1 - t) K + t L
where t is the relative separation from direct K toward point P. To fulfill the 1 to 5 proportion, we can set t = 1/6.
Subbing the qualities into the equation, we get:
P = (1 - 1/6) K + 1/6 L
= 5/6 K + 1/6 L
To find the genuine direction of point P, we want to substitute the directions of K and L into the equation. For instance, if K = (3, 4) and L = (7, 8), the direction of point P can be determined as:
P = (5/6)(3, 4) + (1/6)(7, 8)

cos(θ)=15/17, 15/17<θ<2(pi)
find cotθ
Step-by-step explanation:
cot(θ) = 1/tan(θ)
tan(θ) = sin(θ) / cos(θ)
Given cos(θ) = 15/17, we can find sin(θ) using the Pythagorean identity:
sin(θ) = sqrt(1 - (cos(θ))^2) = sqrt(1 - (15/17)^2) = 4/17
So, tan(θ) = 4/15
And, cot(θ) = 1/tan(θ) = 15/4
Answer: 15/8
Step-by-step explanation: We know that sin(0) will equal 8 by the 8,15,17 triangle. We using the restricted domain value for theta and using the pythagorean identities to get cot(0) as cos(0)/sin(0) and substitute the values. The denominators cancel and the result is 15/8.
What proportion of trucks can be expected to travel between 34 and 50 thousand miles in a year? b. What percentage of trucks can be expected to travel either less than 30 or more than 60 thousand miles in a year? c. How many miles will be traveled by at least eighty percent of the trucks? d. What are your answers to (a) through (c) if the standard devia- tion is 10 thousand miles?
The values of the proportion will be calculated by standardizing the normal distribution and using the Z table to find the values.
Here we are given that the mean distance traveled is 50,000 miles
with a standard deviation of 10,000
Now we need to find the proportion of trucks expected to travel between 34,000 and 50,000
(a)
Now for this, we need to find the area under the given normal curve between 34,000 and 50,000
For this, we need to first find the standard value. Hence we get
(X - μ)/σ
where μ = mean = 50,000
σ = standard deviation = 10,000
Hence we get
(34000 - 50000)/10000
= -1.6
(50000-50000)/10000 = 0
Looking up the value we will get
0.4452
(b)
The percentage of trucks to travel less than 30,000 will be
Z(30,000 - 50,000)/10000
= Z(-2)
looking the value up we will get
0.02275
= 2.275 %
More than 60,00 will be
1 - Z(60000-50000)/10000
= 1 - Z(1)
= 1 - 0.84134
= 0.15866
= 15.866%
Since the question asks "or" it will be a union of the 2 values to get
18.141%
(c)
Now the miles traveled by at least 80% of trucks will have a Z score of 0.8
Now in the Z table, we get the closest to be 0.80234 which has a Z value of 0.85
Now the no. of trucks will be
0.85 X 10000 + 50000
= 8500 + 50000
= 58,500
d)
Now if the standard deviation was 7000 instead of 10,000
The proportion of trucks to travel between 34 and 50 would be
Z(-16000/7000) = Z(-2.29)
0.48713
Percentage of trucks to travel less than 30 or more than 60 thousand miles in a year
is 100[ Z(-20000/7000) + 1 - Z(10000/7000) ]
= 100[Z (-2.86) + 1 - Z(1.43)]
= 100[0.00212 + 1 - 0.92364]
= 100 X 0.07849
= 7.849%

a fair coin is tossed 4 times. what is the probability that there are more heads than tails given that the number of tails is divisible by 3?
The probability of more heads than tails is 1/2 since the number of tails is divisible by 3.
A fair coin is one that has equal chances of being heads or tails when it is tossed. When a fair coin is tossed four times, the probability of getting more heads than tails is 1/2. This is because for each toss, the probability of getting a head or a tail is equal (1/2). This means that the probability of getting more heads than tails is the same as the probability of getting more tails than heads, which is 1/2.
Since the number of tails is divisible by 3, this means that in the four tosses, there must either be 0, 3, or 6 tails. Since there are no other possibilities, the probability of more heads than tails is 1/2 since it is equally likely to get more heads than tails or more tails than heads.

To solve this, you can use the geometric mean theorem. The leg of a right triangle is the geometric mean between the hypotenuse and the portion of the hypotenuse adjacent to the leg.
So that means that 28/y = y/12. You can then use means and extremes of proportions to simplify, and you get y^2 = 336, a.k.a y = 4 root 21.
Then you do the same thing but with x.
28/x = x/16
x^2 = 448
x = 8 root 7
Answer:
B. x = 8√7, y = 4√21
Step-by-step explanation:
Look at the largest right triangle so the hypotenuse equals 12 + 16 = 28
According to the Pythagorean Theorem: y^2 + x^2 = 28^2
Then for the 2 smaller right triangles, they all the the same side, just called it z
so y^2 = 12^2 + z^2 => z^2 = y^2 - 12^2
and x^2 = 16^2 + z^2 => z^2 = x^2 - 16^2
then y^2 - 12^2 = x^2 - 16^2
y^2 - 144 = x^2 - 256
y^2 = x^2 - 112
Using the first equation
y^2 + x^2 = 28^2 => x^2 = 784 - y^2
So we have y^2 = x^2 - 112
and x^2 = 784 - y^2
then y^2 = (784 - y^2) - 112
y^2 + y^2 = 784 - 112
2y^2 = 672
y^2 = 336
y = 4√21
x^2 = 784 - y^2 = 784 - 336 = 448
x = 8√7
Need help finding the slope of the line on the graph
Answer:
2/3-3/4-2undefined40Step-by-step explanation:
You want to find the slopes of the lines shown in the attached graphs.
SlopeThe slope of a line is its "rise" divided by its "run":
m = rise/run
To determine slope from a graph, start at an identified point on the left, and count the grid squares up (+) or down (-) to the same horizontal line as the identified point on the right. This is the "rise". Then count the grid squares horizontally to the identified point. This is the "run". The slope is the ratio of these numbers.
1. rise 4, run 6, slope 4/6 = 2/3
2. rise -3, run 4, slope -3/4
3. rise -6, run 3, slope -6/3 = -2
4. run = 0; division by 0 is "undefined", so the slope is "undefined"
5. rise 4, run 1, slope 4/1 = 4
6. rise 0, run (anything), slope 0/1 = 0
__
Additional comment
It is helpful to remember that a horizontal line has a slope of 0, and a vertical line has a slope that is "undefined." Slope is positive if the line goes up to the right. It is negative if the slope goes down to the right.
Because the slope of a vertical line is "undefined," its equation cannot be written in "slope-intercept" form.
Here, points are marked on the lines. When that is not the case, it usually works well to identify points where the line crosses an intersection of grid lines.
You can also use grid crossings to check your answer for the slope. For example, the line on graph 3 crosses grid intersections that are 2 down and 1 over from the marked points (and other grid intersections), confirming a slope of -2.
the distance between the earth and the moon is approximately feet, and a rocket can travel there at a speed of about 1,540,000 ft/min. how long will it take the rocket ship to travel to the moon and back, in minutes? express your final answer in minutes and round to the nearest minute.
The average distance between the Earth and the Moon is about 238,855 miles or 1.28 light-seconds.
To convert miles to feet, multiply by 5,280, giving us approximately 1.27 million feet. A rocket traveling at a speed of 1,540,000 ft/min would take approximately 82.5 minutes to travel to the Moon. The round trip to the Moon and back would take approximately 165 minutes, or about 2 hours and 45 minutes.
It's important to note that this is an estimate and the actual time it takes may vary due to various factors such as the rocket's trajectory, speed, and other environmental conditions. Also, it's worth noting that this speed is significantly faster than current spacecraft speeds, so the actual time it would take a rocket to travel to the Moon and back is likely to be much longer.

There are 50 marbles in a bag. 35 of the marbles are brown. Otti takes at random a marble from the bag. He records the colour of the marble and puts the marble back in the bag. He does this 300 times. Work out an estimate for the number of brown marbles he takes.
If there are 50 marbles in a bag and 35 of them are brown, and Otti takes one marble and put it back afterwards and does it 300 times, then the estimated number of brown marbles Otti takes is around 105.
The expected number of brown marbles Otti takes can be estimated by multiplying the probability of drawing a brown marble (35/50) by the number of times he draws (300).
(35/50) × 300 = 105
This gives an estimated result of 105 brown marbles. It's important to note that this is just an estimate and the actual number could be different. The variation in the actual number of brown marbles Otti takes can be attributed to the randomness of the process.

HELP QUICK (5 star and brainliest if correct) If masha buys three roses she will have 7 dollars left. To buy nine roses, Masha will need to borrow 11 dollars from her father. How many dollars does Masha have?
Let's start by setting up a system of equations to represent the given information:
3r = m - 7
9r = m + 11
where r is the cost of one rose, and m is the total amount of money that Masha has.
We can solve this system of equations using the elimination method:
Multiplying the first equation by 3, we get:
9r = 3m - 21
Subtracting the second equation from this, we get:
0 = -4m - 32
Simplifying, we get:
m = -8
Therefore, Masha has $-8, which means she owes money. This indicates that there may be an error in the problem statement or data provided.
Answer:
Masha has 16 dollars.
Step-by-step explanation:
3x + 7 = Masha's total money
9x = Masha's total money + 11 (after borrowing)
We can use the first equation to find the value of 3x, which is Masha's total money if she buys three roses:
3x + 7 = Masha's total money
3x + 7 = Masha's total money
3x = Masha's total money - 7
We can substitute the second equation to solve for Masha's total money:
9x = Masha's total money + 11
9x = (3x + 7) + 11
9x = 3x + 18
6x = 18
x = 3
Now we know that one rose costs 3 dollars. We can use the first equation to find Masha's total money if she buys three roses:
3x + 7 = Masha's total money
3(3) + 7 = Masha's total money
9 + 7 = Masha's total money
Masha's total money = 16
A truck that can carry no more than 7100 lb is being used to transport refrigerators and upright pianos. Each refrigerator weighs 250 lb and each piano weighs 425 lb. Write and graph an inequality to show how many refrigerators and how many pianos the truck could carry. Will 12 refrigerators and 11 pianos overload the truck? Explain
Yes, 12 refrigerators and 11 pianos overload the truck, because 12 refrigerators and 11 pianos weighs more than 7100 lb.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given that, a truck that can carry no more than 7100 lb is being used to transport refrigerators and upright pianos
Let the number of refrigerators be x and the number of pianos be y.
Each refrigerator weighs 250 lb and each piano weighs 425 lb.
Here, 250x+425y≤7100
Will 12 refrigerators and 11 pianos overload the truck
Now, put x=12 and y=11 in the inequality 250x+425y≤7100, we get
250×12+425×11≤7100
7675≤7100 not true
Therefore, the inequality represent the given scenario is 250x+425y≤7100.
