Answers

Answer 1

The Law of Sines states that in any triangle, the ratio of the length of a side to the sine of the angle opposite that side is the same for all sides and angles. In other words, if a, b, and c are the lengths of the sides of a triangle, and A, B, and C are the angles opposite those sides, then we have:

a/sin(A) = b/sin(B) = c/sin(C)

In the given triangle, we are given the values of B and c, so we can use the Law of Sines to find the other side lengths and angles. We have:

a/sin(A) = c/sin(C)

Since c = 43 and C = 135°, we can plug these values into the equation to find a:

a/sin(A) = 43/sin(135°)

To find the value of a, we just need to solve for a by multiplying both sides of the equation by sin(A). We have:

a = 43 * sin(A) / sin(135°)

We know the value of B, so we can use the Law of Sines again to find the value of A:

sin(A) / a = sin(B) / b

Since B = 8° and b is unknown, we can plug these values into the equation to find a:

sin(A) / a = sin(8°) / b

To find the value of A, we just need to solve for A by dividing both sides of the equation by sin(A)/a. We have:

A = asin(8°) / b

Now that we know the values of A and c, we can use the Law of Sines one more time to find the value of b:

sin(A) / a = sin(B) / b

Since A and a are unknown, we can plug the known values into the equation to find b:

sin(A) / a = sin(B) / b

To find the value of b, we just need to solve for b by multiplying both sides of the equation by sin(B)/b. We have:

b = sin(B) / (sin(A) / a)

At this point, we have all the necessary values to compute the values of a, A, and b. We can plug the known values into the equations we derived above to find the unknown values.

First, let's find the value of a:

a = 43 * sin(A) / sin(135°)

We know the values of A and B, so we can plug these values into the equation to find a:

a = 43 * sin(A) / sin(135°)

  = 43 * sin(180° - C - B) / sin(135°)

  = 43 * sin(180° - 135° - 8°) / sin(135°)

  = 43 * sin(37°) / sin(135°)

To compute the value of sin(37°), we can use a calculator or look up the value in a table of sines.

A book costs $1.49 and is sold in a retail store for $8.99. What is the percentage in mark up? *​

Answers

Answer:

603.35%

Step-by-step explanation:

Given that a book costs $ 1.49 and is sold in a retail store for $ 8.99, to determine what is the percentage in mark up, the following calculation must be performed:

1.49 = 100

8.99 = X

8.99 x 100 / 1.49 = X

899 / 1.49 = X

603.35 = X

Thus, the mark up percentage of the book is 603.35%, which implies an increase of more than 6 times its initial value.

A manufacturer of band saws wants to estimate the average repair cost per month for the saws he has sold to certain industries. He cannot obtain a repair cost for each saw, but he can obtain the total amount spent for saw repairs and the number of saws owned by each industry. Thus, he decides to use cluster sampling, with each industry as a cluster. The manufacturer selects a simple random sample of n = 20 from the N = 96 industries he services. The data on total cost of repairs per industry and number of saws per industry are as given in the accompanying table. Estimate the average repair cost per saw for the past month and place a bound on the error of estimation.

Total               130                    2,565           19.73

Average = Sum of the total repair cost for past month divided by the number of saws repaired

= 19.73 (2,565/130)

= 20

The bound on error of estimation = the difference between the upper bound of the interval and the calculated mean

= 30 - 20

= 10

The lower bound = 10

The bound of error is also = (30 -10)/2 = 10

Step-by-step explanation:

After watching a video, I got it right on Khan

The equation with completing the squares is (x + 8)² = 77.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 9 is an equation.

We have,

x² + 16x - 2 = 11

We can make complete squares.

x² + 16x - 2 - 11 = 0

x² + 16x - 13 = 0

x² + 2 x 8 x (x) -8² + 8² - 13 = 0

(x² + 16x + 8²) - 64 - 13 = 0

(x + 8)² - 77 = 0

(x + 8)² = 77

Thus,

The equation is (x + 8)² = 77.

Lateral Surface Area =
in squared
Total Surface Area =
in squared
Volume =
in cubed

Answers

Answer:

Step-by-step explanation:

Lateral surface area of the triangular prism = Perimeter of the triangular base × Height

By applying Pythagoras theorem in ΔABC,

AC² = AB² + BC²

(34)² = (16)² + BC²

BC = [tex]\sqrt{1156-256}[/tex]

     = [tex]\sqrt{900}[/tex]

     = 30 in.

Perimeter of the triangular base = AB + BC + AC

                                                      = 16 + 30 + 34

                                                      = 80 in

Lateral surface area = 80 × 22

                                  = 1760 in²

Total Surface area = Lateral surface area + 2(Surface area of the triangular base)

Surface area of the triangular base = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                                           = [tex]\frac{1}{2}(30)(16)[/tex]

                                                           = 240 in²

Total surface area = 1760 + 2(240)

                               = 1760 + 480

                               = 2240 in²

Volume = Area of the triangular base × Height

             = 240 × 20

             = 4800 in³
