what is 7j + 5 - 8k when j = 0.5 and k = 0.25?

Answer: x=4

Step-by-step explanation:

Step 1. turn you y into a 0

0=4x-16

Step 2. get x alone

a.

0  =  4x  -16            

+16           +16

*what you do to one side of the equal sign you must to the other.

b.

0 + 16 = 4x

(divide by 4)  16 = 4x  (divide by 4)

*divide by 4 to get rid of the 4 next to the x, remeber to do both sides of the equal sign

4 = x

Answer:

h(x)= x^2+11x+30

Step-by-step explanation:

A quadratic function is in the form h(x) = ax^2 + bx + c.

Since the zeros are -6 and -5, take the opposite signs and add them to the variable x separately.

It should look like this: h(x)= (x+6)(x+5)

Since this is the factored form, we have to solve this equation further.

h(x)= (x+6)(x+5)

h(x)= x^2+6x+5x+30

h(x)= x^2+11x+30

By calculating the areas of the rectangular faces and the hexagonal bases, and then summing them up, we can find the surface area of the regular hexagonal prism.

A regular hexagonal prism consists of six rectangular faces and two hexagonal bases. To calculate the surface area, we need to determine the areas of these individual components and then sum them up.

Each rectangular face has a length equal to the side length of the hexagon and a width equal to the height of the prism. Therefore, the area of each rectangular face is given by length times width. With a side length of 4.2 millimeters and a height of 3.9 millimeters, the area of each rectangular face is 4.2 mm * 3.9 mm.

Since there are six rectangular faces, the total area of the rectangular faces is 6 times the area of each rectangular face.

Next, we need to calculate the area of each hexagonal base. A regular hexagon is composed of six equilateral triangles, and the area of an equilateral triangle can be determined using the formula: (sqrt(3) / 4) * side length^2. With a side length of 4.2 millimeters, we can calculate the area of each equilateral triangle and then multiply it by 6 to obtain the total area of the hexagonal bases.

Finally, we add the area of the rectangular faces to the area of the hexagonal bases to get the total surface area of the regular hexagonal prism. To round to the nearest tenth, we can apply rounding to the final result.

In summary, by calculating the areas of the rectangular faces and the hexagonal bases, and then summing them up, we can find the surface area of the regular hexagonal prism.

Answer:

0.097%

Step-by-step explanation:

Since this is a series of events probability question, in order to calculate the probability you need to first find the probability of getting each individual answer right and then multiplying those probabilities together. This will give you the probability of getting 100% on the entire test. Since the questions are multiple-choice with 4 choices and only 1 correct choice then the probability of getting one right is 1/4 or 25%. Now that we have that probability we simply need to multiply it 5 times for each individual question.

1/4 * 1/4 * 1/4 * 1/4 * 1/4 = 1/1024 or 0.0009765 or 0.097%

The formula for the degrees of freedom is as follows: df = n1 + n2 - 2where n1 and n2 are the sample sizes of the two populations. Therefore, the correct answer is c. n1 + n2 - 2.

In testing for differences between the means of two related populations where the variance of the differences is unknown, the degrees of freedom are n1 + n2 - 2.The degrees of freedom are very important in statistics, as they tell you how much you can trust your results. The degrees of freedom are related to sample size and are used in various statistical tests, including t-tests and chi-square tests. In this particular case, we are interested in testing for differences between the means of two related populations where the variance of the differences is unknown.In this case, we use a t-test to compare the means of the two populations. The formula for the t-test is as follows:t = (x1 - x2) / (s / √n)where x1 is the mean of the first population, x2 is the mean of the second population, s is the standard deviation of the differences between the two populations, and n is the sample size.

In order to calculate the t-value, we need to know the degrees of freedom. The formula for the degrees of freedom is as follows:df = n1 + n2 - 2where n1 and n2 are the sample sizes of the two populations. Therefore, the correct answer is c. n1 + n2 - 2.

Step-by-step explanation:

To calculate gross pay, multiply the number of hours worked by the pay per hour.

Warren worked 36.5 hours one week and 32 hours the week before.

Therefore, the total number of hours Warren worked was:

Multiply the total number of hours worked by Warren's rate of pay of $21.75 per hour:

Therefore, Warren's gross pay for the two weeks was $1,489.88 (nearest cent).

Answer:

$1489.875

Step-by-step explanation:

Warren's gross pay for 36.5 hours last week can be calculated as follows:

Gross pay for 36.5 hours = $21.75/hour * 36.5 hours = $793.875

Similarly, Warren's gross pay for 32 hours the week before can be calculated as follows:

Gross pay for 32 hours = $21.75/hour * 32 hours = $696

Adding the gross pay for the two weeks, we get:

Gross pay for 2 weeks = $793.875 + $696 = $1489.875

We have proved that angle B is less than angle B' if and only if segment AC is less than segment A'C'.

To prove Proposition 4.6, we will use the triangle inequality theorem and the fact that congruent line segments preserve angles.

Given Triangle ABC and Triangle A'B'C' with the following conditions:

1. Segment AB is congruent to segment A'B'.

2. Segment BC is congruent to segment B'C'.

We want to prove that angle B is less than angle B' if and only if segment AC is less than segment A'C'.

Proof:

First, let's assume that angle B is less than angle B'. We will prove that segment AC is less than segment A'C'.

Since segment AB is congruent to segment A'B', we can establish the following inequality:

AC + CB > A'C' + CB

Now, using the triangle inequality theorem, we know that in any triangle, the sum of the lengths of any two sides must be greater than the length of the remaining side. Applying this theorem to triangles ABC and A'B'C', we have:

AC + CB > AB    (1)

A'C' + CB > A'B'    (2)

From conditions (1) and (2), we can deduce:

AC + CB > A'C' + CB

AC > A'C'

Therefore, we have shown that if angle B is less than angle B', then segment AC is less than segment A'C'.

Next, let's assume that segment AC is less than segment A'C'. We will prove that angle B is less than angle B'.

From the given conditions, we have:

AC < A'C'

BC = B'C'

By applying the triangle inequality theorem to triangles ABC and A'B'C', we can establish the following inequalities:

AB + BC > AC    (3)

A'B' + B'C' > A'C'    (4)

Since segment AB is congruent to segment A'B', we can rewrite inequality (4) as:

AB + BC > A'C'

Combining inequalities (3) and (4), we have:

AB + BC > AC < A'C'

Therefore, angle B must be less than angle B'.

Hence, we have proved that angle B is less than angle B' if and only if segment AC is less than segment A'C'.

Proposition 4.6 is thus established.

"No, triangles ABC and DBE are not similar." Since the ratios of the corresponding side lengths are not equal (2, 3, 2), triangles ABC and DBE are not similar.

To determine whether triangles ABC and DBE are similar, we need to compare their corresponding angles and sides.

1. Compare the ratios of their corresponding side lengths.

Triangle ABC:
Side AB = 10.4
Side BC = 23.4
Side AC = 4

Triangle DBE:
Side DB = 5.2
Side BE = 7.8
Side DE = 2

Now, let's find the ratios of corresponding side lengths:
AB/DB = 10.4/5.2 = 2
BC/BE = 23.4/7.8 ≈ 3
AC/DE = 4/2 = 2

Since the ratios of the corresponding side lengths are not equal (2, 3, 2), triangles ABC and DBE are not similar.

The equation of the line that satisfies the given conditions and passes through the point (3,8) and is perpendicular to the y-axis is x=3. This can be answered by the concept of Simple equations.

A line perpendicular to the y-axis is parallel to the x-axis, and since it passes through the point (3,8), its equation can be written as x = 3. This is because for any point on this line, the x-coordinate will always be 3, and the y-coordinate can be any value, which means the line will be a vertical line passing through (3,8).

Therefore, the equation of the line that satisfies the given conditions and passes through the point (3,8) and is perpendicular to the y-axis is x=3, which is in standard form

Answer:

outer width of trough = outer height of trough = x = 4ft

outer length of trough = 2x = 8ft

Step-by-step explanation:

Let,

x = outer width of trough = outer height of trough

Now, according to given condition:

2x = outer length of trough

Now we calculate the inner dimensions by subtracting the thickness (1 ft)

Therefore,

x - 2(1ft) = x - 2ft = inner width of trough (because 1ft from both sides will be subtracted)

x - 1ft = inner height of trough (because only bottom thickness will be subtracted)

2x - 2ft = inner length of trough (because 1ft from both sides will be subtracted)

Now, for the holding volume or inside volume of trough will be:

\(Inner Volume = 36\ ft^3 = inner\ height*inner\ width*inner\ length \\36 = (x - 1)(x - 2)(2x - 2)\\36 = (x - 1)(2x^2 - 6x + 4)\\36 = (2x^3 - 6x^2 + 4x - 2x^2 + 6x - 4)\\36 = (2x^3 -8x^2 + 10x - 4) \\2x^3 -8x^2 + 10x - 40 = 0\\2x^2(x-4)+10(x-4) = 0\\(x-4)(2x^2+10) = 0\\\)

So, we will have three roots from this solution. Two, of them will be complex from the second factor. So, we ignore them and take the third one as our answer:

x - 4 = 0

x = 4ft

Now the outer dimensions will be:

outer width of trough = outer height of trough = x = 4ft

outer length of trough = 2x = 8ft
