Final answer:
To find the value of ST, we set up the equation 3x + 7x = 10, solve for x, and then calculate ST as 3(1), which gives us ST = 3.
Explanation:
The student is asking to solve for ST, given that ST=3x, TU=7x, and SU=10. This is a segment addition problem, where ST and TU make up the whole segment SU. To solve it, you would first set up the equation ST + TU = SU. Substituting the given values, we get:
3x + 7x = 1010x = 10x = 1After finding the value of x, we substitute it back into the expression for ST:
ST = 3xST = 3(1)ST = 3So, the segment ST is 3 units long.

Final answer:
To find the speed of a dog that covers 24 meters in 52 seconds, divide the distance by the time to get an average speed of approximately 0.4615 meters per second (m/s).
Explanation:
To calculate the speed of a dog running through a yard that covers a distance of 24 meters in 52 seconds, you would use the formula for speed, which is:
Speed = Distance ÷ Time
In this case, the dog covers a distance (Distance) of 24 meters in a time (Time) of 52 seconds. Substituting these values into the formula we get:
Speed = 24 m ÷ 52 s
Now, we perform the division to find the speed:
Speed = 0.4615 meters per second (m/s)
Therefore, the dog is running at an average speed of approximately 0.4615 m/s.

Assuming these stock values continue to increase in the same manner until retirement, which stock option is worth more in 50 years and how much more is this stock worth per share?
OPTIONS:
A) Stock B is worth more in 50 years, $1,575.84 more per share
B) Stock A is worth more in 50 years, $1,364.08 more per share
C) Stock B is worth more in 50 years, $1,796.87 more per share
D) Stock A is worth more in 50 years, $880.00 more per share
Stock B is worth more in 50 years, $1,575.84 more per share.
Explanation:To determine which stock option is worth more in 50 years, we need to find the value of each stock after 50 years.
For Stock A, we have the equation: an = 15n + 130. Plugging in n = 50, we get a50 = 15(50) + 130 = $880.
For Stock B, we have the equation: an = 36(1.09)n - 1, where n is the number of years. Plugging in n = 50, we get a50 = 36(1.09)^50 - 1 = $2,455.84.
Therefore, Stock B is worth more in 50 years, $1,575.84 more per share.

△MNO is rotated about point A to △M′N′O′ . Which statements are true about the pre-image and image? Select each correct answer.
The image is the same shape but a different size than the pre-image.
The image is the same size but a different shape than the pre-image.
MN ≅ M′N′
Answer:
MN ≅ M′N′
Step-by-step explanation:
When you rotate an image on a certain pivot point, you´ll end up with two equal images in shape and form, but with different angles from the center, since the image is the same shape, form and length, their sides and angles should be the same, so the sentece that is true is that MN ≅ M′N′.
Si vendo los 7/4 de lo que no vendí, ¿que parte del total no vendí?
The part of the total that is not sold is 1/4.
If you sell 7/4 of the lot, the part of the total that is not sold is 1 - 7/4 = 1/4.
Another way to think about it is that if you have 4 slices of pie and you sell 7 of them, you have 1 slice left. Therefore, 1/4 of the pie is not sold.
Suppose you have a lot that is 100 square meters in size. If you sell 7/4 of the lot, you will sell 7/4 * 100 square meters = 175 square meters. This means that you will have 100 square meters - 175 square meters = 25 square meters left.
Therefore, the part of the total that is not sold is 25 square meters / 100 square meters = 1/4.
In general, if you sell a fraction of a total, the part of the total that is not sold is 1 - (fraction sold).

You roll a six-sided number cube. Which events are mutually exclusive?
A) rolling a multiple of 2 and a multiple of 4
B) rolling a multiple of 3 and a multiple of 6
C) rolling an even number and an odd number
D) rolling a prime number and an even number
Answer:
C) Rolling an even number and an odd number.
Step-by-step explanation:
We are asked to choose the correct option that represents two mutually exclusive events.
Since we know that mutually exclusive events are those events, who can not happen at the same time. As we cannot have both heads and tails in one toss, either we will get heads or we will get tails.
Let us check our given choices one by one.
A) Rolling a multiple of 2 and a multiple of 4.
Multiples of 2: 2, 4, 6,..
Since 4 is a multiple of 2, so both events are not mutually exclusive and option A is not a correct choice.
B) Rolling a multiple of 3 and a multiple of 6.
Multiples of 3: 3, 6, 9,...
Since 6 is a multiple of 3, so both events are not mutually exclusive and option B is not a correct choice.
C) Rolling an even number and an odd number.
Odd numbers on a cube: 1, 3, 5.
Even numbers on a cube: 2, 4, 6.
Since on one roll of dice we can either have an odd or an even number, both events are not possible with a single roll, therefore, option C is the correct choice.
D) Rolling a prime number and an even number.
Prime number on a cube: 2, 3, 5.
Even numbers on a cube: 2, 4, 6.
We can clearly see that 2 is a prime number and it is even as well, therefore, option D is not a correct choice.
Darcy is buying apples and oranges for a large fruit basket to give away as a door prize at a charity event. apples cost $.24 each and oranges cost $.80 each. she has $12 to spend and would like to purchase at least 20 pieces of fruit total
The system of linear inequalities that represent the situation are

Here is the complete question:
Write a system of linear inequalities to represent this situation.
Darcy is buying apples and oranges for a large fruit basket to give away as a door prize at a charity event. Apples cost $0.24 each and oranges cost $0.80 each. She has $12 to spend and would like to purchase at least 20 pieces of fruit total.
To write a system of linear inequalities to represent the situation, we will consider the statements one after the other.
Let x represent the number of apples and y represent the number of oranges.
From the second statement,
"Apples cost $0.24 each and oranges cost $0.80 each"; and
From the next statement,
"She has $12 to spend"
That means, she can either spend $12 or less than $12.
Therefore, we can write that
$0.24x + $0.80y ≤ $12
Also, from the following statement
"and would like to purchase at least 20 pieces of fruit total"
That means, she will either purchase 20 pieces of fruit or greater than 20 pieces of fruit.
Then we can write that
x + y ≥ 20
Hence, the system of linear inequalities that represent the situation are
$0.24x + $0.80y ≤ $12 and x + y ≥ 20

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros.
1. 7, 1+i
2.
The polynomial function of least degree with rational coefficients, a leading coefficient of 1, and the given zeros 7, 1 + i, and 1 - i is f(x) = x^3 - 9x^2 + 21x - 14.
Explanation:In mathematics, zeros are the x-values where a function touches or crosses the x-axis, or the values where f(x) = 0. When a polynomial has rational coefficients and you have a complex zero (a + bi), the conjugate of that zero (a - bi) also needs to be a zero of the polynomial. This is based on the Complex Conjugate Root Theorem. Hence, in this case, the other zero will be 1 - i.
Since you are given zeroes of 7, 1 + i, and 1 - i, the polynomial function of least degree is obtained by employing the Factor Theorem, which states that if k is a zero of a polynomial, then (x - k) is a factor of the polynomial.
Therefore, f(x) = (x - 7)(x - (1 + i))(x - (1 - i)) = (x - 7)(x^2 - 2x + 2). So, f(x) = x^3 - 9x^2 + 21x - 14 is the polynomial function of least degree with rational coefficients, a leading coefficient of 1, and the given zeros.

A polygon has 10 sides. What is the measure of the interior angles of the polygon?
144 degrees is the measure of the interior angles of the polygon.
What is a polygon?In Mathematics, a polygon can be defined as a two-dimensional geometric figure that consists of straight line segments and a finite number of sides. Additionally, some examples of a polygon include the following:
• Triangle
• Quadrilateral
• Pentagon
• Hexagon
• Heptagon
• Octagon
• Nonagon
Generally speaking, the measure of the angle at the center of a regular polygon is equal to 360 degrees. Therefore, the smallest angle of rotation that maps (carries) a regular polygon onto itself can be calculated by using this formula:
α = 360/n
The sum of the measures of the interior angles of an n-sided polygon is given by the formula:
S = (n - 2) × 180 degrees
So, for a 10-sided polygon, we have:
S = (10 - 2) × 180 = 8 × 180 = 1440 degrees
To find the measure of each interior angle, we divide the sum by the number of angles (which is the same as the number of sides for a polygon):
m = S/n = 1440/10 = 144 degrees
Therefore, each interior angle of a 10-sided polygon has a measure of 144 degrees.
