What is the value of 6a - 5q when a = 3 and q = -4

Answers

The value of 6a - 5q when a = 3 and q = -4 is 38.

To find the value of 6a - 5q when a = 3 and q = -4, we simply substitute the values of a and q into the expression and perform the necessary calculations: 6a - 5q = 6(3) - 5(-4) = 18 + 20 = 38. It's important to note that this type of problem involves substituting values into an algebraic expression and simplifying the result. This is a common skill in algebra and is used extensively in higher-level math courses and many fields of science and engineering.

It's also important to be careful when substituting values, especially with negative numbers, to avoid mistakes in the calculations. With practice, however, this skill can be mastered and used effectively to solve a wide range of problems.

Step 1: Our output value is 700.

Step 2: We represent the unknown value with $x$x​.

Step 3: From step 1 above,$700=100\%$700=100%​.

Step 4: Similarly, $x=42\%$x=42%​.

Step 5: This results in a pair of simple equations:

$700=100\%(1)$700=100%(1)​.

$x=42\%(2)$x=42%(2)​.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{700}{x}=\frac{100\%}{42\%}$

700

x​=

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{700}=\frac{42}{100}$

Therefore, 42% of 700 is 294.

The dollar value of a car is a function f, . of the number of years, t, since the car was purchased. Thefunction is defined by the equations f(t) = 12000*(3/5)^ta. What does the 12,000 tell us about the situationb. What does the 3/5tell us about the situation?C.What will be the value of the car after 3 years?

Answers

Given the following question:

\(f(t)=12000\times(\frac{3}{5})^t\)

Part A:

I believe that the 12,000 tells us the orginal price of the car, or the price the car was purchased for. 12000 is the orginal price of the car.

Part B:

I believe that the 3/5 tells us the decline in value each year after the car has been purchased. Which is why t is the exponet is t was 2 you would have to multiply 3/5 by itself twice and then multiply it by 12000 which further decreases it's value. 3/5 represents the decline in value after T years.

Part C:

t = number of years

t = 3

\(\begin{gathered} f(t)=12000\times\frac{3}{5^{}}^3 \\ \frac{3}{5}^3=\frac{3}{5}\times\frac{3}{5}\times\frac{3}{5} \\ \frac{3}{5}\times\frac{3}{5}=\frac{9}{25} \\ \frac{9}{25}\times\frac{3}{5}=\frac{27}{125} \\ 12000\times\frac{27}{125}=2592 \\ v=2592 \end{gathered}\)

Value of the car after three years will be 2592.

A faer has three sacks of peanuts weighing 24kg,36kg,30kg, and 46kg, respectively. He repacked the peanuts such that the packs have equal weights and the largest weight possible with no peanuts left unpacked. How many kilograms will each pack of peanuts contain?

Answers

The each pack of peanuts contain 125 kg.

To solve the problem, you must add the weight of the sacks together and then divide by the number of equal sacks. In this situation, there are 3 sacks of different weights. In order to achieve equal weights, the following calculations must be made:

The sum of the weights of the sacks is 24 + 36 + 30 + 46 = 136 kg

The maximum weight possible is equal to 34 kg since 136 ÷ 4 = 34

Therefore, each pack of peanuts will weigh 34 kg since they will have an equal weight.

To verify this answer, let's divide the initial sacks into packs with a maximum weight of 34 kg:

Sack 1: 24 kg is less than 34 kg

Sack 2: 36 kg is greater than 34 kg. This can be divided into two packs, each of which is 17 kg. (total 34 kg)

Sack 3: 30 kg is less than 34 kg

Sack 4: 46 kg is greater than 34 kg. This can be divided into two packs, each of which is 23 kg. (total 46 kg)

Therefore, there will be four packs of peanuts, with three weighing 34 kg and the fourth weighing 23 kg. This gives a total weight of 125 kg (3 * 34 + 23) of peanuts.

If the current interest A) $6,900.00 B) $6,057.48 C) $5,989.00 D) $7,567.65 E) $7,134.54

Answers

Therefore, Guy would be willing to pay approximately $5,989.00 today for this investment based on the expected cash flows and the interest rate. The correct option is C) $5,989.00.

The formula for present value of a series of cash flows is given by:

\(PV = C1/(1+r)^1 + C2/(1+r)^2 + C3/(1+r)^3 + ... + Cn/(1+r)^n\)

Where:

PV is the present value,

C1, C2, C3, ..., Cn are the cash flows at different time periods,

r is the interest rate, and

n is the number of time periods.

In this case, the cash flows are $2,000, $1,500, $3,000, and $400, occurring at the end of year 1, year 2, year 3, and year 4, respectively. The interest rate (r) is 6%.

Substituting these values into the formula, we have:

\(PV = 2,000/(1+0.06)^1 + 1,500/(1+0.06)^2 + 3,000/(1+0.06)^3 + 400/(1+0.06)^4\)

Simplifying the expression:

\(PV ≈ 2,000/1.06 + 1,500/1.06^2 + 3,000/1.06^3 + 400/1.06^4\)

Using a calculator, we find that PV ≈ $5,989.00.

A rancher has 400400 feet of fencing to put around a rectangular field and then subdivide the field into 33 identical smaller rectangular plots by placing two fences parallel to one of the field's shorter sides. Find the dimensions that maximize the enclosed area. Write your answers as fractions reduced to lowest terms.

Answers

To maximize the enclosed area, we need to determine the dimensions of the rectangular field that will allow for the largest possible area.

Let's denote the width of the rectangular field as x and the length as y.

The total length of fencing used will be the sum of the four sides of the field, which is equal to 2x + y.

According to the problem, we have 400 feet of fencing available, so we can write the equation:

2x + y = 400

To subdivide the field into 33 identical smaller plots, we need to place two fences parallel to one of the shorter sides. This means that the width of each smaller plot will be x/33, and the length will be y.

The area of each smaller plot is given by A = (x/33) * y.

To maximize the area, we can express the area in terms of a single variable. Let's substitute y = 400 - 2x into the area equation:

A = (x/33) * (400 - 2x)

To find the maximum area, we can take the derivative of A with respect to x and set it equal to zero:

dA/dx = (400 - 4x)/33 = 0

Simplifying the equation, we get:

400 - 4x = 0

Solving for x, we find:

x = 100

Substituting this value back into the equation 2x + y = 400, we can solve for y:

2(100) + y = 400

200 + y = 400

y = 200

Therefore, the dimensions that maximize the enclosed area are x = 100 feet and y = 200 feet.

The area of the rectangular field is A = x * y = 100 * 200 = 20,000 square feet.

Find the ordered triplet (x,y,z) for the following system of equations: x+3y + 2z = 1, 03x+y+5z=10, -2x-3y+z=7

Answers

The ordered triplet (x, y, z) or the following system of equations: x+3y + 2z = 1, 03x+y+5z=10, -2x-3y+z=7 is (-170/127, -89/127, 282/127).

Start with the first equation:

x + 3y + 2z = 1

Isolate x by subtracting 3y and 2z from both sides:

x = 1 - 3y - 2z

Substitute this expression of x into the second equation:

0.3x + y + 5z = 10

Substitute the value of x found in step 2 into this equation:

0.3(1 - 3y - 2z) + y + 5z = 10

0.3 -0.9y -0.6z + y + 5z = 10

0.1y + 4.4z = 9.7

y + 44z = 97

Solve for y by isolating it:

y = 97 - 44z

Substitute this expression of y into the first equation:

x + 3(97 - 44z) + 2z = 1

x + 291 - 132z + 2z = 1

Solve for x:

x = 130z - 290

Substitute this expression of x into the third equation:

-2(130z - 290) - 3(97 - 44z) + z = 7

-260z + 580 - 291 + 132z + z = 7

Solve for z:

127z = 282

z = 282/127

Substitute this value of z into the expression of y:

y = 97 - 44(282/127)

= -89/ 127

Substitute the values of z into the expression of x:

x = 130(282/127) - 290

= - 170/ 127

So the solution of the system of equations is: x = -170/127, y = -89/127, z = 282/127.
