tyrone is twice as old as his daughter. in six years, tyrone will be three times what his daughter's age was six years ago. how old are they at present
At present, Tyrone is 48 years old and his daughter is 24 years old.
Let's start by using variables to represent the ages of Tyrone and his daughter.
Let T be Tyrone's current age and D be his daughter's current age.
We know that Tyrone is twice as old as his daughter, so we can write:
T = 2D
We also know that in 6 years, Tyrone's age will be three times what his daughter's age was six years ago. Six years ago, Tyrone's age was T - 6 and his daughter's age was D - 6. So we can write:
T + 6 = 3(D - 6)
Now we have two equations with two variables, so we can solve for T and D.
First, substitute T = 2D from the first equation into the second equation:
2D + 6 = 3(D - 6)
Simplifying this equation, we get:
2D + 6 = 3D - 18
Add 18 to both sides:
2D + 24 = 3D
Subtract 2D from both sides:
24 = D
So Tyrone's daughter is 24 years old now.
We can use the first equation to find Tyrone's age:
T = 2D = 2(24) = 48
Therefore, Tyrone is 48 years old now.
So at present, Tyrone is 48 years old and his daughter is 24 years old.

V=342,784in
if x and y are the tens digit and the units digit, respectively, of the product 725,278x67,066, what is the value of x+y?
Answer:
To find the tens and units digit of the product, we only need to focus on the last two digits of the product.
First, we multiply 8 x 6, which gives us 48. So the units digit is 8 and we carry-over the 4 to the tens digit.
Next, we multiply 7 x 6, which gives us 42. We add the carry-over 4, which gives us 46. So the tens digit is 6 and we carry-over the 4.
Continuing with the multiplication, we get:
6 x 0 = 0 (no carry-over)
6 x 7 = 42 (carry-over 4)
6 x 2 = 12 (carry-over 1)
Adding the carry-over, we get:
4 + 4 + 1 = 9
Therefore, x+y= 8 + 6 = 14

why is gravitational force between two object usually unnoticeable
Answer:
gravitational attraction is based upon mass.More the mass more the force.When the object is as big as a moon it has a very less gravity.When we are talking about small objects like 2 pencils the force exists but is so weak that no noticabke movement takes place
Answer:
To notice that force, the objects have to have a big mass and be close to each others.
Generally in eveydays life, you don't notice this force since it is weak but that doesn't mean it does't exist.
If you go the space, you can notice this force since planets have big mass. If you get close to the gravitational field of a planet, you will feel a force that is pulling you toward the planet.
for f(x) = 16x5 − 12x4 7x2 − 9x 11 and the interval [0, b], find the value of b so that the midpoint of the interval satisfies the mean value theorem.
The value of b for which the midpoint of the interval [0, b] satisfies the mean value theorem for f(x) is approximately 0.865.
To apply the mean value theorem, we need to find a point c in the interval [0, b] such that f'(c) is equal to the slope of the line joining the endpoints of the interval. Since we are looking for the midpoint of the interval, we can set c = (0 + b)/2 = b/2.
First, we need to find the derivative of f(x):
f'(x) = 80x^4 - 48x^3 + 14x - 9
Next, we need to find the slope of the line joining the endpoints of the interval:
slope = (f(b) - f(0)) / (b - 0)
Since we are looking for the midpoint of the interval, we can rewrite this as:
slope = (f(b) - f(b/2)) / (b - b/2)
Using the midpoint value of c = b/2, the mean value theorem tells us that there exists a point c in the interval [0, b] such that f'(c) = slope.
Therefore, we need to solve the equation f'(c) = slope for b/2:
80(b/2)^4 - 48(b/2)^3 + 14(b/2) - 9 = (f(b) - f(b/2)) / (b - b/2)
Simplifying, we get:
80(b/2)^4 - 48(b/2)^3 + 14(b/2) - 9 = (f(b) - f(b/2)) / (b/2)
Multiplying both sides by b/2, we get:
80(b/2)^5 - 48(b/2)^4 + 14b/2 - 9b/2 = f(b) - f(b/2)
Substituting the expression for f(x), we get:
80(b/2)^5 - 48(b/2)^4 + 7(b/2)^2 - 9(b/2) + 11 - [16(b)^5 - 12(b)^4 + 7(b)^2 - 9b + 11]/2 = 0
Simplifying and solving for b, we get:
b = 0.865

Solve the system of equations
Answer:
(-1, 2)
Step-by-step explanation:
1.) The way to use elimination is to add or subtract both of the equations together to eliminate a variable. If we add the two equations together, the -6x and 6x cancel out. Since we added the equations together, -12y and 10y would add up to -2y, and -18 and 14 would add up to -4
2.) Now, we have the equation -2y = -4. By dividing by -2 on both sides, we get y=2.
3.) Next, we need to substitute y back in to get the x value. If you use the first equation, we get -6x - 12 * 2 = -18.
4.) By simplifying, you get that -6x - 24 = -18. If you add 24 on both sides, you get -6x = 6, and by dividing by -6 on both sides, you get x = -1.
5.) Finally, you have to put the answer in form of a point. -1 would be the x-coordinate and 2 would be the y-coordinate. Therefore, the point is (-1, 2)

John has 15 T-shirts. The information shows the colours of his T-shirts. 6 black,2 dark blue,3 red,1 light blue,2 purple,1 pink John is going to take one of his T-shirts at random. He takes one of his blue T-shirts at random. What is the probability that the T-shirt is dark blue?
The probability that the T-shirt John picks is dark blue is 2/3.
To find the probability that John picks a dark blue T-shirt, we'll need to consider the total number of blue T-shirts and the number of dark blue T-shirts.
Determine the total number of blue T-shirts.
John has 2 dark blue and 1 light blue T-shirt, so he has a total of 2 + 1 = 3 blue T-shirts.
Determine the number of dark blue T-shirts.
John has 2 dark blue T-shirts.
Calculate the probability.
The probability that John picks a dark blue T-shirt is the number of dark blue T-shirts divided by the total number of blue T-shirts.

Answer:
x = 22.5
Step-by-step explanation:
the segment from the vertex to the base is an angle bisector and divides the opposite side ( base) into segments that are proportional to the other two sides, that is
\(\frac{9}{x-9}\) = \(\frac{12}{18}\) = \(\frac{2}{3}\) ( cross- multiply )
2(x - 9) = 27
2x - 18 = 27 ( add 18 to both sides )
2x = 45 ( divide both sides by 2 )
x = 22.5

An experimenter would like to construct a 99% confidence interval with a width at most 0.5 for the average resistance of a segment of copper cable of a certain length. If the experimenter knows that the standard deviation of such resistances is 1.55. How big a sample should the experimenter take from the population
The experimenter should take a sample of at least 68 copper cable segments to achieve a 99% confidence interval with a width of no more than 0.5.
Since a sample size must be a whole number, To construct a 99% confidence interval with a width of at most 0.5 for the average resistance of a copper cable segment, the experimenter needs to determine an appropriate sample size. To do this, they must consider the standard deviation (1.55) and the desired level of confidence.
For a 99% confidence interval, the z-score is approximately 2.576. The formula for calculating the required sample size (n) is:
n = (z * σ / E)²
where z is the z-score, σ is the standard deviation, and E is the desired margin of error (half of the confidence interval width, or 0.25 in this case).
n = (2.576 * 1.55 / 0.25)²
n ≈ 67.49

what are two different methods for solving a real-world problem that can be represented by an equation
Subtraction Property of Equality and Addition Property of Equality are two different approaches to resolving a real-world problem that can be depicted by an equation.
What is defined as the Addition Property of Equality?When the identical quantity is added to the both sides of an equation, it generates an equivalent equation, according to the addition property of equality.
2 = 1+1, for example, is an equation given that both the right and left sides of the equal sign symbolize the number 2. However, by adding the number 3 to both sides, this same new equation 2 +3 = 1 + 1 + 3 is founded. As a result of the Addition Property of Equality, if a = b, then a + c = b + c.What is defined as the Subtraction Property of Equality?To maintain equality, if we deduct a number from one side of the equality, we must subtract the very same number from the opposite side of the equality.
Consider the equation X = Y. If a real number 'b' is deducted from the LHS of X = Y, we should then subtract b from Y, so X - b = Y - b. As a result, the formula is as follows:X = Y : X - b = Y - bThus, Subtraction Property of Equality as well as Addition Property of Equality are two different ways of solving a real-world problem that may be represented by an equation.
