Answer:

15

Step-by-step explanation:

(12/8) ×10 is the correct answer

If triangle JKL is similar to triangle RST then the value of x is 15.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

Triangle JKL is similar to triangle RST

Let us find the value of x by forming a proportional equation

10/x = 8/12

Apply cross multiplication

120=8x

Divide both sides by 8

x=15

Hence, if triangle JKL is similar to triangle RST then the value of x is 15.

We need to see Hazel's work for simplifying an inequality and see if she had a mistake or not.

The answers are:

a) Step 4.

B) She did not change the direction of the inequality symbol.

a) Let's analyze each step:

She starts with:

3*(t + 1) - 4*t ≥ −5

Step 1:

3t +3−4t ≥ −5

Here what she does is distributing the first product, she goes from:

3*(t + 1) to 3*t + 3

Step 2:

−t+3≥−5

Here what she did is adding "3*t - 4*t = (3 - 4)*t = -t"

Step 3:

−t ≥ −8

Here she subtracts 3 in both sides.

Step 4:

t ≥ 8

Here is the mistake.

B)

Here what she does is multiplying by -1 in both sides, her mistake is that we multiply both sides by a negative number in an inequality, the direction of the inequality must change, so here is her error.

So what she actually should had is:

-t  ≥ -8

(-1)*(-t) ≤ (-1)*(-8)

t ≤ 8

Answer:

2 photographs

Step-by-step explanation:

Mark as Brainliest.

Because I am Indian and solving your question from India.

Your family buys two photographs at a comic convention.

The equations are defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let x be the number of autographs and y be the number of photographs. We know that:

x + y = 5 (the total number of autographs and photographs)

20x + 50y = 160 (the total cost of the autographs and photographs)

We are looking for the number of photographs (y) that your family buys.

We can use the first equation to solve for x in terms of y:

x = 5 - y

Then we can substitute this expression for x into the second equation:

20(5 - y) + 50y = 160

100 - 20y + 50y = 160

50y = 60

y = 12/5

y = 2.4

Since the number of photographs has to be a whole number, we can see that your family buys 2 photographs.

(a) The sequence an = n^2e^-n is convergent, and it converges to zero.

(b) The sequence an = cos(n)/n^3 is convergent, and it converges to zero.

(a) To show that the sequence an = n^2e^-n converges to zero, we can use the ratio test or the limit comparison test. Using the ratio test, we have lim (n+1)^2e^-(n+1)/(n^2e^-n) = lim (n+1)^2/n^2e = lim (n+1)/n^2 = 0, which is less than 1. Therefore, the sequence converges. Alternatively, we can use the limit comparison test with bn = e^-n. Then, lim n^2e^-n/e^-n = lim n^2 = ∞, which is a finite positive number. Therefore, both sequences have the same convergence behavior, and an converges to zero.

(b) To show that the sequence an = cos(n)/n^3 converges to zero, we can use the squeeze theorem, which states that if 0 ≤ bn ≤ an ≤ cn for all n beyond some index N, and lim bn = lim cn = L, then lim an = L. Here, we have -1/n^3 ≤ cos(n)/n^3 ≤ 1/n^3 for all n, and both -1/n^3 and 1/n^3 converge to zero. Therefore, an converges to zero by the squeeze theorem. Alternatively, we can use the Dirichlet test, which states that if the sequence {bn} is decreasing and converges to zero, and the sequence {an} has bounded partial sums, then the series ∑ anbn converges. Here, we can choose bn = 1/n^2, which is decreasing and converges to zero, and an = cos(n)/n, which has bounded partial sums (by the Dirichlet test for series). Therefore, the series ∑ cos(n)/n^3 converges, and its terms must converge to zero.

When Tracey pours all the water from the smaller 5-inch cube container into the larger 7-inch cube container, the water will be approximately 7 inches deep in the larger container.

To find out how deep the water will be in the larger container, we need to consider the volume of water transferred from the smaller container. Since both containers are cube-shaped, the volume of each container is equal to the length of one side cubed.

The volume of the smaller container is 5 inches * 5 inches * 5 inches = 125 cubic inches.

When Tracey pours all the water from the smaller container into the larger container, the water completely fills the larger container. The volume of the larger container is 7 inches * 7 inches * 7 inches = 343 cubic inches.

Since the water fills the larger container completely, the depth of the water in the larger container will be equal to the height of the larger container. Since all sides of the larger container have the same length, the height of the larger container is 7 inches.

Therefore, the water will be approximately 7 inches deep in the larger container.

The value of k such that the vertical line x = k divides region R into two regions of equal area is approximately 0.7227.

What is Area?

Area is defined as the amount of two-dimensional space that a shape occupies. It can be calculated by multiplying two lengths of a shape, such as the length and width of a rectangle. Area units are always length units squared.

To find the area of region R, we need to integrate the function that defines the upper boundary of the region with respect to x. In this case, the upper boundary is given by y = 3sin(x/2).

To determine the area of R, we can integrate the function from x = 0 to x = (2pi)/3:

A = ∫[0, (2pi)/3] 3sin(x/2) dx

Using the integral property ∫sin(ax) dx = -1/a * cos(ax), we can rewrite the integral as:

A = -6 ∫[0, (2pi)/3] cos(x/2) dx

Evaluating the integral, we get:

A = -6 * [sin(x/2)]|[0, (2pi)/3]

Now we substitute the upper and lower limits into the equation:

A = -6 * [sin((2pi)/6) - sin(0)]

Since sin(0) = 0, the equation simplifies to:

A = -6 * sin((2pi)/6)

Simplifying further:

A = -6 * sin(pi/3)

Using the value of sin(pi/3) = sqrt(3)/2, we get:

A = -6 * (sqrt(3)/2)

A = -3sqrt(3)

However, area cannot be negative, so we take the absolute value:

|A| = 3sqrt(3)

Therefore, the area of region R is 3sqrt(3).

To find the value of k such that the vertical line x = k divides region R into two equal areas, we need to find the x-coordinate of the line of symmetry.

Let's assume the line of symmetry intersects x = k. We want the areas on both sides of the line to be equal, so the areas from x = 0 to x = k and from x = k to x = (2pi)/3 should be equal.

The total area of region R is 3sqrt(3), so the area on each side of the line of symmetry should be (1/2) * 3sqrt(3) = (3/2)sqrt(3).

Let's set up the equation to find k:

∫[0, k] 3sin(x/2) dx = (3/2)sqrt(3)

Using the same integral and evaluating it, we get:

-6 * [sin(x/2)]|[0, k] = (3/2)sqrt(3)

-6 * sin(k/2) = (3/2)sqrt(3)

Dividing both sides by -6 and multiplying by 2/3, we have:

sin(k/2) = -sqrt(3)/4

Taking the inverse sine (arcsin) of both sides, we get:

k/2 = arcsin(-sqrt(3)/4)

To find the value of k, we need to consider the range of the arcsine function. The range of arcsin(x) is -pi/2 ≤ arcsin(x) ≤ pi/2.

Since we're looking for the positive value of k, we need to consider the positive range of arcsin. Thus:

k/2 = arcsin(-sqrt(3)/4)

k = 2 * arcsin(-sqrt(3)/4)

Evaluating this expression using a calculator, we find:

k ≈ 0.7227

Therefore, the value of k such that the vertical line x = k divides region R into two regions of equal area is approximately 0.7227.

Answer:

Step-by-step explanation:

To find the sales tax percentage, we need to determine how much of the total price was due to sales tax. To do this, we can subtract the price of the cupboard from the total price:

$92.82 - $85.78 = $7.04

So the sales tax was $7.04. We can then divide the sales tax by the price of the cupboard and multiply by 100% to find the sales tax rate as a percentage:

$7.04 / $85.78 * 100% = 8.2%

Rounding to the nearest tenth, the sales tax rate was 8.2%.

Answer:

8.2% (rounded to the nearest tenth)

Step-by-step explanation:

$92.82-$85.78= $7.04
