Find m in equation, W=1/2*m*v squared?
Answers
Answer: To find the value of m in the equation W = 1/2 * m * v^2, you need to know the values of W and v. The variable m represents the mass of the object, and W represents the kinetic energy of the object. The equation states that the kinetic energy of an object is equal to 1/2 of its mass multiplied by its velocity squared.
If you are given the values of W and v, you can solve for m by rearranging the equation as follows:
m = 2 * W / v^2
Plugging in the values of W and v will give you the value of m.
For example, if W = 100 joules and v = 10 meters per second, the equation would be:
m = 2 * 100 joules / 10 m/s^2 = 20 kilograms
This is the mass of the object.
\(m=\frac{2W}{v^{2} }\).
Step-by-step explanation:1. Write the expression.\(W=\frac{1}{2} mv^{2}\)
2. Divide both sides of the equation by \(\frac{1}{2}\) and \(v^{2}\).\(\frac{W}{\frac{1}{2} v^{2} }=m\\ \\\)
3. Rewrite and simplify.\(m=\frac{W}{\frac{1}{2} v^{2} }\\ \\m=\frac{2W}{v^{2} }\).

\(-BrainiacUser1357-\)
Answer:
Step-by-step explanation:
It looks like you need to solve this system of equations.
That means we need to find a value for x and a value for y that makes both equations true.
Since both equations have a 3y in them, this system is ready to use a method called "elimination method"
Since the x terms are lined up, and the y terms are lined up, the equal signs are lined up, and the constants are lined up...you can subtract the bottom equation from the top equation.
5x + 3y = 41
2x + 3y = 20
Subtract and you will get
3x + 0y =21
We don't need to write that 0y, because it is 0.
3x = 21, now divide by 3
x = 7, almost finished!
Use x = 7 in either of the original equations to find y.
5x + 3y = 41 and x = 7
5•7+ 3y = 41
35 + 3y = 41
-35 -35
3y =6
y = 2
So the solution is x=7 and y=2

Answers
The standard deviation of the probability distribution for the given price of each doughnut and the variance is equal to $√1.50 × 3.6.
Price of the each doughnut 'P' = $1.50
Expected value of the probability distribution of the doughnut = 2.6
Variance of the probability distribution = 3.6
Price of the variance of the probability distribution is equal to
= Price of each doughnut × Variance
= 1.50 × 3.6
Standard deviation of the probability distribution is equal to

Jody plans to invest a total of $7000
between two different accounts. She has
done some research and found a savings
account that will pay 2.5% interest per year
and a money market account that pays 6%
per year. If she wants to earn $385 after
one year, how much should she invest in
each account?
Answers
Jody plans to invest a total of $7000 between two different accounts. She needs to invest $1000 in her first account and $6000 in her second account to earn $385 after one year.
Let denote p with the amount invested on 2.5% interest per yearLet (7000 -p) denote the amount invested on 6% interest per yearFor the first part
2.5% of p = 0.025pFor the second part
6% of (7000 - p) = 0.06(7000 - p)The total interest is:
= 0.025p + 0.06(7000 - p)
= 0.025p + 420 - 0.06p
Since the total interest she wants to earn after one year is $385.
Then;
385 = 0.025p + 420 - 0.06p
385 - 420 = 0.025p - 0.06p
- 35 = -0.035p
p = - 35/ -0.035
p = 1000
Now;
On the first account, the amount Jody should invest in is p = $1000
On the second account, the amount Jody should invest in is:
= 7000 - p
= 7000 - 1000
= $6000
To confirm this claim,
2.5% of 1000 = 0.025 × 1000 = $256% of 6000 = 0.06 × 6000 = $360$385
Therefore, we can conclude that she needs to invest $1000 in her first account and $6000 in her second account to earn $385 after one year.

Step-by-step explanation:
L x W x H
6 x 5 x 6
180
Answer: 180 cubic centimeters
Step-by-step explanation:
Each little blue cube measures 1 cm in each direction - width, height, and depth.
The volume of the whole figure is just the volume of all the little cubes, added up.
The block of cubes is 5 cubes wide and has a depth of 6 cubes. So each horizontal layer is 5 * 6 = 30 cubes, total.
The block of cubes is 6 layers deep, so we have 6 layers of 30 cubes each = 6 * (30 cubes) = 180 cubes in all.
Each cube is 1 cubic centimeter (abbreviated 1 cc), so 180 of them have a combined volume of 180 cc.
A shorter way to say all this is to say that V = width * depth * height =
= 5 cm * 6 cm * 6 cm = (5)(6)(6) cm³ = 180 cubic centimeters
there are 9 red markers, 5 blue markers, 14 yellow markers, and 8 green markers in a pencil box. A marker is chosen at random, replaced, then another is chosen. Find each probability.
P(yellow, then red)
P(blue, then green)
P(both red)
Answers
We will see that the probabilities are:
P(yellow, then red) = 0.1P(blue, then green) = 0.03P(both red) = 0.06How to find the probabilities?
First, the probability of getting a particular color of marker is given by the quotient between the number of markers of that color and the total number of markers
There are:
9 red markers.
5 blue markers.
14 yellow markers
8 green markers.
For a total of: 9 + 5 + 14 + 8 = 36.
a) P(yellow, then red)
First, the probability of getting a yellow marker is:
p = 14/36.
Then the probability of getting a red marker (notice that now there are 35 markers in total) is:
q = 9/35.
Then the joint probability is:
P(yellow, then red) = p*q = ( 14/36)*(9/35) = 0.1
b) P(blue, then green)
First, the probability of getting a blue marker is:
p = 5/36.
After, the probability of getting a green marker is:
q = 8/35.
So the joint probability is:
P(blue, then green) = (5/36)*(8/35) = 0.03
c) P(both red).
First, the probability of getting a red marker is:
p = 9/36
Now there are 8 red markers and 35 markers in total, so the probability of getting another red marker is:
q = 8/35
The joint probability is:
P(both red) = (9/36)*(8/35) = 0.06

A line segment has end points V (-4, -4) and W (11, 2). What is the x-coordinate of the point that is 2/5 of the way from V to W on this line segment?
Answers
After answering the presented question, we can conclude that We only coordinates need the positive solution, so t = 1.259
what are coordinate ?A coordinate in mathematics is a number or combination of integers that indicates the position of a point or object in space. Coordinates are often used to define the position of a point or object in a certain coordinate system, such as the Cartesian or polar coordinate systems. A point, for example, is located in the Cartesian coordinate system by its distance from the origin along the x-axis and its distance from the origin along the y-axis. These distances are denoted by two numbers, the x-coordinate and the y-coordinate, respectively. The two coordinates specify the point's position in the plane.
To find the point that is 2/5 of the way from V to W, w
\(d = \sqrt((x2 - x1)^2 + (y2 - y1)^2)\\\)
where (x1, y1) = (-4, -4) and (x2, y2) = (11, 2).\\
\(d = \sqrt((11 - (-4))^2 + (2 - (-4))^2)\\= \sqrt(15^2 + 6^2)\\= \sqrt(225 + 36)\\= \sqrt(261)\\\)
\(d1 = (2/5) * \sqrt(261)\\x = -4 + t * (11 - (-4))\\d1 = s\qrt((x - (-4))^2 + (y - (-4))^2)\\= \sqrt((x + 4)^2 + y^2 - 8x - 8y + 32)\\\)
\(d1^2 = (x + 4)^2 + y^2 - 8x - 8y + 32\\d1^2 = (x + 4)^2 + y^2 - 8x - 8y + 32\\= (x + 4)^2 + y^2 - 8(x + 4) - 8y + 64 \\d1^2 = (x + 4)^2 + y^2 - 8(x + 4) - 8y + 64\\= (x + 4)^2 + (y - 4)^2 + 4 )\\(2/5)^2 * 261 = (x + 4)^2 + (y - 4)^2 + 4\\\)
\(52.2 = (x + 4)^2 + (y - 4)^2 + 4\\(x + 4)^2 + (y - 4)^2 = 48.2\\(x + 4)^2 + y^2 - 8x - 8y + 32 = 48.2 \\(x + 4)^2 + (-4 + 6t)^2 - 8x + 48t - 32 = 48.2\\(x + 4)^2 + 36t^2 - 48t + 32 = 48.2\\(x + 4)^2 + 36t^2 - 48t - 16.2 = 0\\\)
Using the quadratic formula:
\(t = (48 + sqrt(48^2 - 4 * 36 * (-16.2))) / (2 * 36)\\= (48 + sqrt(2596.8)) / 72\\= (48 + 50.956) / 72\\t = 1.259 or t = -0.705\\\)

Charlie the trainer has two solo workout plans that he offers his clients: Plan A and plan B. Each client does either one or the other (not both). On Wednesday there were 5 clients who did plan A and 6 who did plan B. On Thursday there were 3 clients who did plan A and 2 who did plan B. Charlie trained his Wednesday clients for a total of 7 hours and his Thursday clients for a total of 3 hours. How long does each of the workout plans last?
Answers
Plan A lasts for 0.5 hours, and Plan B lasts for 0.75 hours based on the given information and the solution to the System of equations.
To determine the duration of each workout plan, let's assume that both Plan A and Plan B have a fixed duration. Let's denote the duration of Plan A as "x" hours and the duration of Plan B as "y" hours.
From the given information, we can form the following equations:
On Wednesday:
5 clients did Plan A, so the total duration for Plan A is 5x hours.
6 clients did Plan B, so the total duration for Plan B is 6y hours.
The total training duration on Wednesday is 7 hours, so we have the equation: 5x + 6y = 7 ... Equation (1)
On Thursday:
3 clients did Plan A, so the total duration for Plan A is 3x hours.
2 clients did Plan B, so the total duration for Plan B is 2y hours.
The total training duration on Thursday is 3 hours, so we have the equation: 3x + 2y = 3 ... Equation (2)
We now have a system of equations (Equation 1 and Equation 2) that we can solve to find the values of x and y.
Multiplying Equation (1) by 2 and Equation (2) by 5 to eliminate the y variable, we get:
10x + 12y = 14 ... Equation (3)
15x + 10y = 15 ... Equation (4)
Multiplying Equation (3) by 3 and Equation (4) by 2 to create a new system of equations:
30x + 36y = 42 ... Equation (5)
30x + 20y = 30 ... Equation (6)
Subtracting Equation (6) from Equation (5), we can eliminate the x variable:
(30x + 36y) - (30x + 20y) = 42 - 30
16y = 12
y = 12/16
y = 0.75
Substituting the value of y into Equation (2), we can solve for x:
3x + 2(0.75) = 3
3x + 1.5 = 3
3x = 3 - 1.5
3x = 1.5
x = 1.5/3
x = 0.5
Therefore, the duration of Plan A is 0.5 hours, and the duration of Plan B is 0.75 hours.
Plan A lasts for 0.5 hours, and Plan B lasts for 0.75 hours based on the given information and the solution to the system of equations.
