To simplify this expression, we can follow the order of operations:

1. Simplify the expression inside the parentheses first:

(3x2^y - 2 - 7x2^(y-2))

2. Combine like terms:

3x2^y - 7x2^(y-2) - 2

3. Rewrite the denominator with a common base of 2:

5x2^(y-2)

4. Divide the numerator by the denominator:

(3x2^y - 7x2^(y-2) - 2) ÷ (5x2^(y-2))

5. Simplify by dividing each term in the numerator by 5x2^(y-2):

(3x2^y)/(5x2^(y-2)) - (7x2^(y-2))/(5x2^(y-2)) - (2/(5x2^(y-2)))

6. Simplify the exponents:

(3/5)x^(y-2) - (7/5) - (2/5)x^(-2)

So the final simplified expression is:

(3/5)x^(y-2) - (7/5) - (2/5)x^(-2)

there are 312 cubic inches of wood left after cutting out a square hole with side lengths of 5 inches from a cube-shaped block with side lengths of 8 inches.

How to find the volume ?

To find the volume of the remaining wood, first find the volume of the cube-shaped block. To find the volume of a cube use V = s³ where s is the side of the cube. In this case, s = 8 inches, so V = 8³ = 512 cubic inches.

Then, find the volume of the hole using the side lengths of the hole and the same depth as the cube, which is 8 inches. The hole has side lengths of 5 inches, so its volume is V = 5² * 8 = 200 cubic inches.  

To find how much wood is left after cutting out the hole, subtract the volume of the hole from the volume of the cube:

512 - 200 = 312 cubic inches

Therefore, there are 312 cubic inches of wood left after cutting out a square hole with side lengths of 5 inches from a cube-shaped block with side lengths of 8 inches.

Answer:

Correct option is Option A

Step-by-step explanation:

By using a protractor or visual estimation, we can estimate the measure of angle ABC to the nearest degree.

To answer your question, let's first start with defining what an angle is. An angle is formed by two rays or line segments that share a common endpoint, called the vertex. The measure of an angle is usually given in degrees and is determined by how much the two rays are turned away from each other.

Now, let's look at the specific angle you asked about, angle ABC. Without a diagram or any additional information about the position of point B and C, it is impossible to determine the measure of angle ABC. However, we can make some general assumptions based on the fact that angle measures range from 0 to 360 degrees.

Assuming that angle ABC is a standard angle and not a reflex angle (i.e. it measures less than 180 degrees), we can estimate the measure of angle ABC to the nearest degree by using a protractor or by visual estimation. A protractor is a tool used to measure angles in degrees, and can be found at most office supply stores or online.

If we don't have access to a protractor, we can still estimate the measure of angle ABC by comparing it to other angles we know the measure of. For example, if angle ABC looks to be about halfway between a right angle (90 degrees) and a straight angle (180 degrees), we can estimate that angle ABC measures around 135 degrees.

In summary, without additional information about the specific position of points B and C, we cannot determine the exact measure of angle ABC. However, by using a protractor or visual estimation, we can estimate the measure of angle ABC to the nearest degree.

The given expression 14 - 0.6t  is representing the amount of fuel that has been remaining after "t" days of use.

14 - 0.6t is an algebraic expression. The car had 14 gallons of fuel at first and after each day of use, the car used 0.6 gallons which means that the amount of fuel that is remaining in the car at the end of the day is continuously decreasing by 0.6 per day. So, after "t" days of use, the car must have 0.6×t gallons of fuel, and the amount of fuel that remains in the car will be 14 - 0.6t.

When the warning light comes on, the remaining fuel is 1.5 gallons or less. So we can set the expression 14 - 0.6t to 1.5 and solve for t to find the number of days it takes for the warning light to come on:

14 - 0.6t = 1.5

0.6t = 12.5

t = 20.83

Therefore, it takes approximately 20.83 days of use for the warning light to come on.

Helping in the name of Jesus.

The scale factor is 2. Point B goes from (3,3) to (6,6). 6/3 is 2. Similar triangles have the same shape and the three angles' measurements are likewise the same.

Their sides are the only thing that differs. The scale factor, which is what is referred to here as this, is the ratio of one triangle's sides to those of another triangle. To calculate the scale factor for the smaller triangle to the bigger triangle, divide one of the sides in the bigger triangle by its corresponding side in the smaller triangle. In the example, the scale factor would be 2 if you divided 40 by 20.

Answer:

x = -30

y = 18

Step-by-step explanation:

-2,4x - 3y is equal to both 18 and y

Since there are two equal signs, we have a double equation (we can write each equation seperately and put them in a system):

{y = -2,4x - 3y,

{-2,4x - 3y = 18;

.

We move 3y to the left, so we change the sign to the opposite:

{4y = -2,4x, / : 4 (put y and 3y together)

{-2,4x - 3y = 18;

.

y = -0,6x,

-2,4x - 3y = 18;

Replace y in the 2nd equation with its value from the 1st equation:

-2,4x - 3 × (-0,6x) = 18

-2,4x + 1,8x = 18

-0,6x = 18 / : (-0,6)

x = -30

y = -0,6 × (-30) = 18

Answer:

x ≥ 5

Step-by-step explanation:

Let's represent the number of action figures in a complete set by the variable "x".

Carlos has 5 complete sets plus 4 individual figures, which is a total of:

5x + 4

Josh has 3 complete sets plus 14 individual figures, which is a total of:

3x + 14

The problem states that Carlos has at least as many action figures as Josh, so we can set up the inequality:

5x + 4 ≥ 3x + 14

Simplifying this inequality, we can subtract 3x from both sides:

2x + 4 ≥ 14

Then, we can subtract 4 from both sides:

2x ≥ 10

Finally, we divide both sides by 2:

x ≥ 5

Therefore, the inequality that represents how many action figures can be in a complete set is:

x ≥ 5

The probability that the part can be assembled in 7 minutes or less is 0.2592.

To solve the problem, we need to use the cumulative distribution function (CDF) of the exponential distribution. The CDF gives the probability that the random variable X (in this case, the time required to assemble the part) is less than or equal to a certain value x.

The CDF of the exponential distribution is given by:

F(x) = [tex]1 - e^{(-λx)}[/tex]

where λ is the rate parameter of the exponential distribution, which is equal to 1/mean. In this case, the mean is 14 minutes, so λ = 1/14.

To find the probability that the part can be assembled in 7 minutes or less, we plug x = 7 and λ = 1/14 into the CDF formula: F(7) = [tex]1 - e^{(-(1/14)*7)} \approx 0.2592[/tex]

The correct explicit rule is f(n) = 50 + 30n

An explicit rule is a mathematical formula that directly gives the n-th term of a sequence or the value of a function for a given input, without the need to find other terms first. It can be expressed using variables, constants, and operations such as addition, subtraction, multiplication, and division.

To determine who is correct, we need to first understand the meaning of the variables in the explicit rules.

Let n be the number of days the car is rented for.

Let f(n) be the cost of renting the car for n days.

The deposit is a one-time charge and is not dependent on the number of days rented. Therefore, the constant term in the explicit rule should be 50.

Now, for each day rented, the cost is $30. This means that the cost for n days should be 30n.

So the correct explicit rule is:

f(n) = 50 + 30n

Therefore, Kevin is correct with the explicit rule f(n) = 50 + 30(n-1). This is because we subtract 1 from n since the deposit is charged only once at the beginning and is not included in the daily rate.

Suzanne's explicit rule, f(n) = 80 + 30(n-1), adds an extra $30 to the cost of renting the car, which is not correct.
