Ted is five times as old as Rosie was when Ted was Rosie's age. When Rosie
reaches Ted's current age, the sum of their ages will be 72. Find Ted's current age.
Answer:
45 yo
Step-by-step explanation:
Let's start by defining some variables to represent the ages of Ted and Rosie:
- Let's call Ted's current age "T"
- Let's call Rosie's current age "R"
From the problem statement, we know that:
- Ted is five times as old as Rosie was when Ted was Rosie's age. Written as an equation, this becomes:
T = 5(R - (T - R))
Simplifying this equation, we get:
T = 5(R - T + R)
T = 10R - 5T
- When Rosie reaches Ted's current age, the sum of their ages will be 72. Written as an equation, this becomes:
R + T = 72 - T
We now have two equations with two variables. We can use substitution to solve for T.
Substitute the second equation into the first equation to eliminate R:
T = 10R - 5T
T = 10(72 - T) - 5T
T = 720 - 15T
16T = 720
T = 45
Therefore, Ted's current age is 45.

The expected value of the area of t is 1/12.
The length of the hands of the clock is 1. If a time of day is chosen uniformly at random, what is the expected value of the area of t?
The area of the triangle is given by the formula
A=1/2 ab sinC.
Here, we use Law of cosines to determine the angle C, which is enclosed by the hour and minute hands.
[tex](\cos C)_{h,m}=\frac{h^2+m^2-1}{2hm}[/tex]
So, we can write the expected value of the area of t as

How to find the minimum, maximum?In statistics, the five-number summary is a set of descriptive statistics that provide a summary of the distribution of a dataset. The five-number summary consists of the minimum value, the first quartile (Q1), the median (M), the third quartile (Q3), and the maximum value.
To find the five-number summary for the given data on the number of calories in a hot dog for each of 17 brands of meat hot dogs, we need to order the data from smallest to largest.
107 135 136 138 139 146 147 153 172 173 175 179 182 190 191 195
The minimum value is the smallest value in the dataset, which is 107.
The first quartile (Q1) is the value that is greater than or equal to 25% of the data and less than or equal to 75% of the data. To find Q1, we take the median of the lower half of the data:
Q1 = median(107, 135, 136, 138, 139, 146, 147, 153) = 138
The median (M) is the value that is in the middle of the dataset when the data is ordered from smallest to largest. For the given data, there are 17 values, so the median is the 9th value:
M = median(107, 135, 136, 138, 139, 146, 147, 153, 172, 173, 175, 179, 182, 190, 191, 195) = 175

Assume that x and y are both differentiable functions of t and find the required values of dy/dt and dx/dt.x2+y2=100a) Find dy/dt when x=6, y=8 given that dx/dt=4.b) Find dx/dt when x=8, y=6 given that dy/dt=-2.
a) When x = 6 and y = 8, and dx/dt = 4, the value of dy/dt is -3.
Using implicit differentiation, we have:
2x(dx/dt) + 2y(dy/dt) = 0
Solving for dy/dt, we get:
dy/dt = -(x/y)(dx/dt)
Substituting x = 6, y = 8, and dx/dt = 4, we get:
dy/dt = -(6/8)(4) = -3
Therefore, when x = 6 and y = 8, and dx/dt = 4, the value of dy/dt is -3.
b) Using implicit differentiation again, we have:
2x(dx/dt) + 2y(dy/dt) = 0
Solving for dx/dt, we get:
dx/dt = -(y/x)(dy/dt)
Substituting x = 8, y = 6, and dy/dt = -2, we get:
dx/dt = -(6/8)(-2) = 1.5
Therefore, when x = 8 and y = 6, and dy/dt = -2, the value of dx/dt is 1.5.
To find the values of dy/dt and dx/dt, we used implicit differentiation, which is a technique used to find the derivative of an equation that is not expressed in the form y = f(x).
In this case, we had the equation x^2 + y^2 = 100, and we differentiated both sides of the equation with respect to t. Then, we solved for the required derivative using the given values of x, y, and the other derivative.

What is trigοnοmetric equatiοns ?Trigοnοmetric equatiοns are equatiοns that invοlve trigοnοmetric functiοns such as sine, cοsine, tangent, etc. These equatiοns usually invοlve finding values οf the unknοwn angle(s) that satisfy the given equatiοn. They can be sοlved using algebraic techniques οr by using the prοperties οf trigοnοmetric functiοns.

In this case, a = -5, b = 20, and c = -18. Substituting these values intο the quadratic fοrmula, we get:
[tex]t = (-b\± \sqrt{(b^2 - 4ac)}) / 2a[/tex]
Plugging in the values οf a, b, and c, we get:

7. What is the greatest whole number that satisfies the inequality
3x - 1 < 8 ?
Answer:
2
Step-by-step explanation:
3(2)-1<8
6-1<8
5<8
if you go up to 3 as the whole number then the equation ends up 8<8, and the sign is less than (<) not less than or equal to.
So 2 would be the answer.
You construct three 88% confidence intervals as follows: A) A t-interval with 6 degrees of freedom. B) A t-interval with 2 degrees of freedom. C) A z-interval Assuming the mean and standard deviation are the same for all three intervals, write the three intervals (A, B, and C) in order, from narrowest to widest.
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. A low standard deviation means data are clustered around the mean, and a high standard deviation indicates data are more spread out.
A) A t-interval with 6 degrees of freedom: Mean +/- 0.76 * Standard Deviation
B) A t-interval with 2 degrees of freedom: Mean +/- 1.82 * Standard Deviation
C) A z-interval: Mean +/- 1.645 * Standard Deviation
Therefore, the intervals in order from narrowest to widest are:
A) A t-interval with 6 degrees of freedom,
C) A z-interval, and
B) A t-interval with 2 degrees of freedom.
The order from narrowest to widest is:
C) z-interval
A) t-interval with 6 degrees of freedom
B) t-interval with 2 degrees of freedom
Also,
The z-interval will be the narrowest because the z-distribution has a smaller variance than the t-distribution. The t-interval with 6 degrees of freedom will be wider than the z-interval because the t-distribution has a larger variance than the z-distribution.
Finally, the t-interval with 2 degrees of freedom will be the widest because the t-distribution has the largest variance when degrees of freedom is low.

An art collector buys a replica of a famous sculpture. The replica has exactly the same shape as the original but it is smaller. The replica is 12 cm tall, and the original sculpture is 28 cm tall. If 162 cm^3 of bronze was needed to make the replica, how much bronze was needed to make the original sculpture?
2052 cm³ volume of bronze was needed to make the original sculpture.
What is volume?Volume is a physical quantity that refers to the amount of space occupied by a three-dimensional object or substance. It is typically measured in cubic units such as cubic meters, cubic centimeters, or cubic feet.
What is Area?Area is a physical quantity that refers to the amount of space within a two-dimensional shape or surface. It is typically measured in square units such as square meters, square centimeters, or square feet.
In the given question,
Since the replica is a scaled-down version of the original sculpture, the ratio of their sizes is the same as the ratio of their volumes.
The ratio of the heights of the original sculpture to the replica is:28 cm / 12 cm = 7/3
Therefore, the ratio of the volumes is:(7/3)³ = 343/27.
This means that the original sculpture is about 12.7 times larger than the replica in terms of volume.
Since 162 cm³ of bronze was needed to make the replica, we can find the amount of bronze needed for the original sculpture by multiplying 162 cm³ by the volume ratio:162 cm³ x 343/27 = 2052 cm³.
Therefore, 2052 cm³ of bronze was needed to make the original sculpture.

g a second unit vector which is also orthogonal to both 8,-8,8 and 0,5,5 is the unit vector which points in the direction opposite to u1 -2/6.-1/6,1/6 this is the vector u2
The vector u2 is (0, √3/3, 2/3). It is a unit vector that is orthogonal to both 8,-8,8 and 0,5,5.
Given two vectors 8,-8,8 and 0,5,5, we need to find another unit vector that is orthogonal to both the given vectors. Let's call this vector u1.The vector u1 can be obtained by taking the cross product of the two given vectors:u1 = (8,-8,8) × (0,5,5)u1 = (-40,-40,40)
To get a unit vector, we need to normalize u1 by dividing it by its magnitude:|u1| = √((-40)² + (-40)² + 40²) = 60u1 = (-40/60, -40/60, 40/60) = (-2/3, -2/3, 1/3)Now we need to find another unit vector that is orthogonal to u1.
One way to do this is to take the cross product of u1 with another vector, and then normalize the result. We can choose any vector that is not parallel to u1. For example, we can choose the vector (1,0,0).u2 = u1 × (1,0,0)u2 = (-2/3, -2/3, 1/3) × (1,0,0)u2 = (0,1/3,2/3)
To get a unit vector, we need to normalize u2 by dividing it by its magnitude:|u2| = √(0² + (1/3)² + (2/3)²) = 1/√3u2 = (0, √3/3, 2/3)

The simple interest on a certain sum at 5% per annum for 3 years and 4years differ by rupees 82 find the sum
The principal sum is Rs. 1640 if the difference in simple interest between 3 years and 4 years is Rs. 82 at a rate of 5% per annum.
Let x be the principal sum. According to the problem, the difference in simple interest between 3 years and 4 years is Rs. 82. This means that the interest earned in the fourth year is Rs. 82 more than the interest earned in the third year.
Using the formula for simple interest, we can calculate the interest earned in each year:
Simple interest for 3 years = (x * 5% * 3) = 0.15x
Simple interest for 4 years = (x * 5% * 4) = 0.2x
The difference between the two is:
0.2x - 0.15x = 0.05x
We are given that this difference is equal to Rs. 82, so:
0.05x = 82
Solving for x, we get:
x = 82 / 0.05 = 1640
Therefore, the principal sum is Rs. 1640.

f(x)= (2x-2)(x − 3)
-
Use the Add Point tool to plot the zeros and the maximum or minimum value of the function.
The zeros of the function are x=1 and x=3, and the minimum value of the function is at x=2.
What is the polynomial function?
A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation, etc.
To find the zeros, we set the function equal to zero and solve for x:
(2x-2)(x-3) = 0
This equation is true when either 2x-2=0 or x-3=0. Solving for x in each case, we get:
2x-2=0 => x=1
x-3=0 => x=3
So the zeros of the function are x=1 and x=3.
To find the maximum or minimum value of the function, we can take the derivative of the function and set it equal to zero:
f'(x) = 4x - 8
4x - 8 = 0 ----> x = 2
So the critical point of the function is x=2. To determine if this point is maximum or minimum, we can use the second derivative test:
f''(x) = 4
Since f''(2) > 0, the function has a minimum at x=2.
Therefore, the zeros of the function are x=1 and x=3, and the minimum value of the function is at x=2.

To solve the question asked, you can say: So the other side of the triangle will be as [tex]A = \sqrt73[/tex].
What precisely is a triangle?A triangle is a closed two-dimensional geometric object consisting of three line segments, called edges, that intersect at three places called vertices. Triangles are distinguished by their sides and angles. A triangle can be equilateral (all sides equal), isosceles, or odd, depending on the sides. Triangles are classified as acute (any angle less than 90 degrees), right (angles equal to 90 degrees), or obtuse (any angle greater than 90 degrees). The area of a triangle can be calculated using the formula A = (1/2)bh. where A is the area, b is the base of the triangle, and h is the height of the triangle.
here in the triangle we have sides that are 3 and 8
we can use
[tex]A^2 = B^2 + C^2\\A^2 = 3^2 + 8^2\\A^2 = 9+64\\A^2 = 73\\A = \sqrt73[/tex]

QS and TV areparallellines. P Q R S T U V W Which angles are vertical angles?
The required angles ∠SRP and ∠TUW are alternate exterior angles.
What is alternate exterior angles?Alternate exterior angles are a pair of angles that lie on opposite sides of a transversal line that intersects two other lines. Specifically, the angles are exterior to the two intersecting lines and lie on opposite sides of the transversal.
More formally, if two parallel lines are intersected by a transversal, then alternate exterior angles are the pair of angles that are:
On opposite sides of the transversal line.
Outside of the two parallel lines.
Congruent to each other.
These angles are called "alternate" because they are on opposite sides of the transversal and "exterior" because they are outside of the two parallel lines. The congruence of the angles is a result of the parallel lines creating equal corresponding angles.
So,∠SRP and ∠TUW are alternate exterior angles.

How much would it cost to buy a sheet of a metal 4m by 75cm which cost E90 to a metal of 5m by 2m
It would cost €27 to buy a sheet of area 4 meters by 75 centimeters.
We solve this problem easily by employing the unitary method. To answer this question, we need to first calculate the area of the metal sheet being sold and the area of the metal sheet being purchased.
The area of the metal sheet being sold is:
5 meters × 2 meters = 10 square meters
The area of the metal sheet being purchased is:
4 meters × 0.75 meters = 3 square meters
Now we can calculate the price per square meter of the metal sheet being sold:
€90 ÷ 10 square meters = €9 per square meter
Finally, we can calculate the cost of the metal sheet being purchased:
3 square meters × €9 per square meter = €27. Therefore, the cost to buy a sheet of area 4 meters by 75 centimeters which costs €90 to a metal of area 5 meters by 2 meters would be €27.
