you have been given 5 gallons 1 quart 2 pints of water for 11 marines. how much water will each marine receive?

Answers

The amount of water that each marine would receive is 4 pints.

How much water would each marine receive?

The first step is to convert the quantity of water to the same unit.

1 gallon = 8 pints

8  x 5= 40 pints

1 quart = 2 pints

Total quantity of water = 40 + 2 + 2 = 44 pints of water

The next step is to determine how much water each marine would receive.

Amount each marine would receive = total pints / amount each marine would receive

44 / 11 = 4 pints

Range: x 17

Domainc All real numbers

Range: g(x) = 61

Answers

The domain of g(x) is all real numbers, and the range is (61, ∞) and the range is (61, ∞).

The domain of a function is the set of all possible input values for which the function is defined, while the range is the set of all possible output values.

For the given function g(x) = -1/4 (x−17)² + 61, the domain is all real numbers since there are no restrictions on the input values.

To find the range, we can use the fact that the vertex of the parabola is at (17, 61) and the coefficient of the squared term is negative, indicating a downward opening parabola.

Thus, the maximum value of the function occurs at the vertex and is 61, which is also the minimum possible value. Therefore, the range is (61, ∞).

In summary, the domain of g(x) is all real numbers, and the range is (61, ∞).

Answers

The Salesman's salary is modeled by the linear equation:

y = $1000 + $500*x

How to write a function for the salesman's salary?

We know that the businessman earns a basic salary of $1000 (it does not depend on how many items he sells) and $500 for each item he sells as a commission.

Then, if we define x as the number of items he sells, the amount he gets in commissions is: x*$500

Then the equation for his total salary, y, in terms of x which is defined above is:

y = $1000 + $500*x

That is the linear equation we wanted to write.

You have now invested some money in your bank account with an interest rate of 5% every year. At year 3 , you will find out that you have $30,000 in your bank account. How much money will you have in your bank account at year 2?

a. $25,915.13
b. $27,210.88
c. $28,571.43
d. $30,000.00
e. None of the above

Answers

At year 2, you will have approximately $25,915.13 in your bank account, assuming an initial investment with a 5% interest rate compounded annually. The correct answer is (a).


To find out how much money you will have in your bank account at year 2, we can use the compound interest formula:
A = P(1 + r/n)^(nt)
Where:
A = Final amount (in this case, $30,000)
P = Principal amount (initial investment)
R = Annual interest rate (5% or 0.05)
N = Number of times interest is compounded per year (assumed to be once per year)
T = Number of years (in this case, 3)
Let’s solve for P, the principal amount at year 0:
30,000 = P(1 + 0.05/1)^(1*3)
30,000 = P(1.05)^3
Dividing both sides of the equation by (1.05)^3:
P = 30,000 / (1.05)^3
P ≈ 25,915.13
Therefore, at year 2, you will have approximately $25,915.13 in your bank account.
The correct answer is (a) $25,915.13.

A car is traveling at a steady speed. It travels 1 1/2 miles in 2 1/4 minutes. How far will it travel in 46 minuets? In 1 hour?

Answers

Answer:

30.667, in 1 hour = 40 miles

Step-by-step explanation:

Set up a proportion so 1.5 miles / 2.25 minutes.

So 1.5/2.25 = x/46

solve for x 1.5(46)/2.25 = x so x = 30.667

In one hour is 60 minutes so  1.5(60)/2.25 = x

Answers

The half-life of caffeine in the body is approximately 5-6 hours, not 666 hours. Given this information, we can calculate the latest time Charlotte can drink a 222-ounce shot of espresso that contains 80mg of caffeine and still have no more than 2020mg of caffeine in her system at 11pm.

What does math's % mean?

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

We know that after 5-6 hours, the amount of caffeine in the body decreases by 50%. Therefore, in 11 hours, the amount of caffeine in the body would decrease by approximately 87.5%.

If we let x be the number of hours before 11pm that Charlotte can drink the espresso, then the amount of caffeine in her body at 11pm would be:

80mg * (1 - (87.5% ^ (x/5-6))) = 2020mg

Solving for x, we find that the latest time Charlotte can drink the espresso is approximately 6:30pm.

An equation is a mathematical statement that shows that two expressions are equal. It contains an equals sign "=" that separates the two expressions, with the expression on the left-hand side of the equals sign being equal to the expression on the right-hand side. Equations can involve variables, which are typically represented by letters and can take on different values. Solving an equation means finding the value or values of the variable(s) that make the equation.

by the question.

let's simplify the equation step by step:

2(4-x) - 12 = 36 + 2x (start with the given equation)

8 - 2x - 12 = 36 + 2x (distribute the 2)

-4 - 2x = 36 + 2x (combine like terms)

\frac{24u^{3}}{6u^{7}}

Answers

The value of the expression by taking the common factors is \(\frac{24u^{3}}{6u^{7}} = \frac{4u^3}{u^7} = \frac{4}{u^4}\).

What is a fraction?

A mathematical phrase that expresses a portion of a whole is a fraction. It is expressed as a/b, where a and b are the numerator and denominator, respectively. The denominator is the total number of components that make up the whole, whereas the numerator is the number of parts that we have.

For instance, we can write 2/5 if we have 2 of 5 pizza slices. When representing values that fall between whole numbers, like 1/2 or 3/4, as well as values higher than 1, like 5/4 or 7/2, fractions can be utilized.

It is possible to multiply, divide, add, subtract, and convert fractions between multiple number systems, including mixed numbers and decimals.

The given expression can be simplified by taking the common factors of the numerator and the denominator as follows:

\(\frac{24u^{3}}{6u^{7}} = \frac{4u^3}{u^7} = \frac{4}{u^4}\)

Hence, the value of the expression by taking the common factors is \(\frac{24u^{3}}{6u^{7}} = \frac{4u^3}{u^7} = \frac{4}{u^4}\).

Answers

(a) the velocity of S' relative to S is given by v = (12α₁t)e_x - (9α₂t² - 21α₃)e_y + 4α₃e_z, (b) the accelerations of particles in both S and S' are given by a = 12α₁e_x - 18α₂te_y.

(a) To calculate the velocity v with which S' is moving relative to S, we need to differentiate the position vector r'(t) with respect to time:

v = dr'/dt = (12α₁t)e_x - (9α₂t² - 21α₃)e_y + 4α₃e_z

The resulting velocity vector v represents the velocity of S' relative to S.

(b) The acceleration of a particle in S with position vector r can be found by differentiating the velocity vector with respect to time:

a = dv/dt = 12α₁e_x - 18α₂te_y

Similarly, the acceleration of a particle in S' with position vector r' can be found by differentiating the velocity vector of S' with respect to time:

a' = dv'/dt = 12α₁e_x - 18α₂te_y

Therefore, both the particle in S and the particle in S' experience the same acceleration, which is given by 12α₁e_x - 18α₂te_y. The accelerations are the same in both frames, indicating that they are moving relative to each other with the same acceleration.

(c) To determine if S' is an inertial reference frame, we need to consider whether the laws of physics hold true in S'. In an inertial reference frame, Newton's laws of motion should be valid without the need for any additional forces.

From the given information, the acceleration in S' depends on time (as it includes the term -18α₂t), which suggests the presence of a non-inertial force. Therefore, S' is not an inertial reference frame.

A system of linear equations: y + 2x = -5 and 8x + 4y = -20  has infinitely many solutions.

The 3 possible solutions of a linear system are:

- Unique or one solution

- Infinite solutions

- No solution

If the linear equations are exactly (or can be transformed to exactly) the same equations, the solution is infinite.

The given linear system is:

y + 2x = -5           ....... (equation 1)

8x + 4y = -20     ..........(equation 2)

Rearrange equation 1 to:

Answers

point coordinates for the mid segment of the parallel to PQ segment of the PQR is ST point is (-3.5, 0.5) and (-1, -0.5).

Given that,

We have to find what are the endpoint coordinates for the middle portion of the parallel to PQ segment of the PQR.

We know that,

First we write the co-ordinates of the triangle in the given graph.

P is (-3,3)

Q is (2,1)

R is (-4,-2)

The triangle's midpoint, which is parallel to section PQ, must be located. As a result, we would need to locate the midpoints of the segments PR and QR before joining the points to obtain the mid segment.

Midpoint Formula is

(x₁+x₂/2, y₁+y₂/2)

So,

The midpoint of the side PR is

(-3+(-4)/2, 3+(-2)/2)

(-3-4/2, 3-2/2)

(-7/2,1/2)

So, S point is (-3.5, 0.5)

The midpoint of the side QR is

(2+(-4)/2, 1+(-2)/2)

(2-4/2, 1-2/2)

(-2/2,-1/2)

So, T point is (-1, -0.5)

Therefore, The endpoint coordinates for the mid segment of the parallel to PQ segment of the PQR is ST point is (-3.5, 0.5) and (-1, -0.5).

Answers

The registers that are changed during the evaluate address phase of an LC-3 LDR instruction are the Base Register and the MAR (Memory Address Register).

During the evaluate address phase of the LDR instruction, the Base Register is used to calculate the effective address. It holds the base address of the memory location from which data is being loaded. The value stored in the Base Register is added to the offset specified in the instruction to compute the effective address.

The MAR (Memory Address Register) is the register that holds the computed effective address during the evaluate address phase. It is responsible for storing the memory address to be accessed for the LDR instruction.

Other registers, such as the General Purpose Registers (R0-R7) and the MDR (Memory Data Register), are not changed during the evaluate address phase of the LDR instruction.
