Thomas won $16,000 on a game show, and he put all of the money in a checking account (which does not give interest). Each month, he takes $400 out of the account for "spending" money.


The equation that describes this situation is M=16000−400t

, where t

is the time in months since opening the account, and M

is the amount of money left in the account.


In how many months will Thomas empty the account (which means that there will be no money left)?

Answers

Answer 1

It will take Thomas 40 months to empty the account if he continues to take out $400 each month of $16,000.

To find out how many months it will take for Thomas to empty the account, we need to set M to 0 and solve for t. This will give us the number of months it will take for Thomas to spend all of the $16,000 he won on the game show. The equation we need to solve is:
0 = 16000 - 400t

First, we'll isolate the variable t on one side of the equation by adding 400t to both sides:
400t = 1600

Next, we'll divide both sides of the equation by 400 to get the value of t:
t = 16000/400

Simplifying the right side of the equation gives us:
t = 40

So, it will take Thomas 40 months to empty the account if he continues to take out $400 each month for spending money.

what are 2 equations for d 2 miles and t 30 minutes

Answers

two equations are: v = u + 0.5a and (v)² = (u)² + 4a.

What is expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given, the distance traveled by an object in t = 30 minutes is 2 miles

Let "v" be the final velocity of an object,

"u" be the initial velocity of an object,

and "a" be the acceleration of an object.

From the standard velocity equation:

final velocity = initial velocity + acceleration * time.....(1)

(final velocity)² = (initial velocity)² + 2*acceleration * distance....(1)

From equation (1)

v = u + a*30 minutes

time in hours,

v = u + 0.5a

From equation (2)

(v)² = (u)² + 2*a* 2

(v)² = (u)² + 4a

therefore, two equations are: v = u + 0.5a and (v)² = (u)² + 4a.

fuel pressure in the fuel tank of the space shuttle is decreasing at a rate of r(t)= 17e^-0.1t psi per second at time t in seconds. at what rate is pressure decreasing at 15 seconds

Answers

The pressure is decreasing at a rate of approximately 0.26 psi/s at t = 15 seconds.

What is pressure ?

In physics, pressure is the amount of force applied per unit area. It is a scalar quantity, which means that it has a magnitude but no direction. Pressure is typically denoted by the symbol P, and its units are commonly expressed in pascals (Pa), which is the SI unit of pressure.

Pressure can be defined as the amount of force F applied per unit area A:

P = F / A

For example, if a force of 100 newtons (N) is applied to an area of 2 square meters (m^2), then the pressure would be:

P = 100 N / 2 m^2 = 50 Pa

Pressure is an important concept in many areas of physics, including fluid dynamics, thermodynamics, and atmospheric science. It is commonly used to describe the behavior of gases and liquids under different conditions, such as changes in temperature or volume. Pressure can also be used to calculate other physical properties, such as the flow rate of a fluid or the speed of sound in a gas.

According to given condition :

The rate of change of the fuel pressure in the fuel tank of the space shuttle is given by the derivative of the function [tex]r(t) = 17e^(-0.1t)[/tex]psi per second with respect to time t. Taking the derivative of r(t), we get:

[tex]r'(t) = (-0.1) * 17e^(-0.1t)[/tex]Simplifying this expression, we get:

[tex]r'(t) = -1.7e^(-0.1t)[/tex]

To find the rate at which the pressure is decreasing at t = 15 seconds, we substitute t = 15 into the expression for r'(t):

[tex]r'(15) = -1.7e^(-0.1*15)[/tex]

r'(15) ≈ -0.26 psi/s

Therefore, the pressure is decreasing at a rate of approximately 0.26 psi/s at t = 15 seconds.

mai poured 2.6 of water into a partially-filled pitcher. the pitcher now contains 10.4.mai wants to know how many liters of water was originally in the pitcher.

Answers

Answer:

Step-by-step explanation:

Let's call the original volume of water in the pitcher "V". Then, after Mai added 2.6 liters, the total volume of water in the pitcher became V + 2.6 = 10.4 liters.

To find the original volume of water in the pitcher, we can isolate V by subtracting 2.6 from both sides of the equation:

V + 2.6 = 10.4

V = 10.4 - 2.6

V = 7.8 liters

So the original volume of water in the pitcher was 7.8 liters.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Sleeping 8 hours a day is the same as sleeping 10 days a month.

In according to hours the number of hours sleeping in month will be

= 8 x 30

What is point-slope form?

The general form of a linear equation is y-y1=m(x-x1). It draws attention to the line's slope and one of the line's points (that is not the y-intercept).

To understand more about it and see some instances, watch this video.

Both the slope-intercept form and the point-slope form can be used to write the equation of a straight line.

The slope and ANY point on the line are highlighted using the point-slope form.

Slope intercept form merely shows the slope and the y-intercept of a line.

So, we have:

m = 1

And points are (12, -2) and (6, -8)

We need to use the points: (12, -2)

Now, form the equation as follows:

y - (-2) = m (x-12)

y + 2 = 1(x-12)

In this case, the lengths of the legs of the right triangle are 2x + 3 and 4x - 1. We can use these values to set up the equation:

(2x + 3)² + (4x - 1)² = c²

Simplifying the left-hand side:

The triangle represents 1/4 of the whole trapezoid, the rhombus represents 1/2 of the whole trapezoid, and the hexagon represents 1/1 of the whole trapezoid.

Determine the fraction

Each of the shapes represent a different fraction of the whole trapezoid.

The triangle represents 1/4 of the whole trapezoid. This is because there are four triangles in the trapezoid, and each one is equal in size. Therefore, each triangle is 1/4 of the whole trapezoid. The rhombus represents 1/2 of the whole trapezoid. This is because there are two rhombuses in the trapezoid, and each one is equal in size. Therefore, each rhombus is 1/2 of the whole trapezoid.

The hexagon represents 1/1 of the whole trapezoid. This is because there is only one hexagon in the trapezoid, and it is equal in size to the whole trapezoid. Therefore, the hexagon is 1/1, or the whole trapezoid.

In conclusion, the triangle represents 1/4 of the whole trapezoid, the rhombus represents 1/2 of the whole trapezoid, and the hexagon represents 1/1 of the whole Hexagon. These fractions can be used to determine the value of each shape in relation to the whole trapezoid.

Can a continuous random variable take all values in an interval?

Answers

A continuous random variable can take all values in an interval, assuming that the interval is unbounded.

This is because a continuous random variable has an infinite number of possible outcomes, and the probability density function (PDF) of a continuous random variable is defined over a range of values rather than specific values.

For example, consider the normal distribution, which is a common continuous probability distribution. The PDF of a normal distribution is a bell-shaped curve that extends from negative infinity to positive infinity.

This means that a continuous random variable following a normal distribution can take any value on the real number line, with some values being more likely than others.

However, if the interval is bounded, then it is possible for a continuous random variable to not take all values within the interval. In this case, the probability density function is zero outside of the interval, and the random variable is restricted to the range of values within the interval.

The breadth of a rectangle is half of its length. If its perimeter is 76m,find its length and breadth.​

Answers

The length and breadth of the rectangle are 25.33 meters and 12.67 meters,

What is a rectangle?

A rectangle is a quadrilateral having four sides and the sum of the angles is 180 in the rectangle the opposite two sides are equal and parallel and the two sides are at 90-degree angles.

We are given that the breadth of the rectangle is half of its length, so we can write:

B = 0.5L

We are also given that the perimeter of the rectangle is 76m. The perimeter of a rectangle is the sum of the lengths of all four sides, which in this case is:

Perimeter = 2(L + B)

Substituting the value of B from the first equation, we get:

Perimeter = 2(L + 0.5L)

Perimeter = 2(1.5L)

Perimeter = 3L

Now we can solve for L:

3L = 76

L = 25.33

So the length of the rectangle is 25.33 meters.

To find the breadth, we can substitute this value of L back into the first equation:

B = 0.5L

B = 0.5(25.33)

B = 12.67

So the breadth of the rectangle is 12.67 meters.

Therefore, the length and breadth of the rectangle are 25.33 meters and 12.67 meters, respectively.

The smallest pair of 4-digit numbers such that the difference between them is 303 and their HCF is 101 are 1010 and 1313.

HCF (Highest Common Factor) of two numbers, which is the largest number that divides both numbers evenly.

Let's call the smaller of the two numbers "x". The larger number would be "x + 303".

The HCF of these two numbers must be 101, which means that 101 must be a factor of both x and x + 303.

To find the smallest possible value of x, we need to find the smallest number that is divisible by 101 and also a 4-digit number.

The smallest multiple of 101 that is a 4-digit number is

=> 101 x 10 = 1010.

Therefore, x = 1010.

The larger number would be

=> x + 303 = 1010 + 303 = 1313.

To check if the HCF of these two numbers is indeed 101, we can use the Euclidean Algorithm or the Prime Factorization method to find the HCF.
