In order to find the height of 2 different 3-D shapes, we must identify which dimension represents the height for each individual shape and then add them together.

The first thing is that we must identify which dimension represents the height for each individual shape, for instance, if one shape is a rectangular prism, its height would be the length of one of its sides.

After we identified the height for each shape, you can add them together to get the total height of the composite figure, but, we must understand that this method assumes that the two shapes are stacked vertically on top of each other with their bases aligned.

The unknown measures and angle measures are:

A. LH ≈ 45.68; m∠K ≈ 55°; m∠L ≈ 35°

Trigonometry deals with the relationship between the ratios of the sides of a right-angled triangle with its angles.

The  unknown measures of the triangle can be founding as follow:

LH² = 56² - 32.4²  (Pythagoras Theorem)

LH = √(56²- 32.4²)

LH = 45.68 units

sin K = 45.68/56

K = sin⁻¹(45.68/56)

K ≈ 55°

Thus, m∠K ≈ 55°

sin L =  32.4/56

L = sin⁻¹( 32.4/56)

L ≈ 35°

Thus, m∠L ≈ 35°

The equation represents circle A is (x + 1)² + (y + 1)² = 25. (option d)

To represent a circle on a coordinate plane, we use an equation called the equation of the circle. This equation is derived from the distance formula, which you might have learned in your geometry class. The equation of a circle with center (a, b) and radius r is given by:

(x - a)² + (y - b)² = r²

In this question, the center of the circle is given as A (1, 1). So, the equation of the circle will be of the form:

(x - 1)² + (y - 1)² = r²

To find the value of r, we can use the fact that point B (5, 4) lies on the edge of the circle. The distance between the center of the circle (1, 1) and point B (5, 4) is equal to the radius of the circle. Using the distance formula, we can find the distance between these two points:

r = √((5 - 1)² + (4 - 1)²) = √(16 + 9) = √(25) = 5

So, the equation of the circle can be written as:

(x - 1)² + (y - 1)² = 5²

Simplifying this equation, we get:

(x - 1)² + (y - 1)² = 25

Therefore, the correct answer is option d) (x + 1)² + (y + 1)² = 25.

The proportion of the tapestries' height to width is 3:2, which means the height is 1.5 times the width.

To find the proportion of the tapestries' height to width using whole numbers and ratio notation, we need to divide the height of the tapestry by its width.

The height of the tapestry is 1.5 meters, and the width is 1 meter. Therefore, the proportion of the tapestry's height to width is

1.5 meters / 1 meter = 1.5 : 1

We can simplify this ratio by dividing both sides by 1, which gives

1.5 : 1 = 3/2 : 1

Therefore, the proportion of the tapestry's height to width using whole numbers and ratio notation is 3:2.

Answer:

AB is not a tangent. The lengths 4, 12, and 13 do not form a right triangle.

√(4^2 + 12^2) = √160, which is not equal to 13.

Answer:

No

Step-by-step explanation:

if AB is a tangent the the angle BAC = 90°

using Pythagoras' theorem

then square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

BC² = 13² = 169

AB² + AC² = 12² + 4² = 144 + 16 = 160

since BC²≠ AB² + AC²

then Δ ABC is not a right triangle so AB is not a tangent

The polynomial  (2m + 2n)6 = 12m + 12n.

For the long division, the quotient is x - 2, the remainder is 6, and the dividend can be written as (x - 2)(x² - 4x + 3) + 6.

To expand the expression (2m + 2n)6, using the distributive property of multiplication over addition:

(2m + 2n)6 = 2m(6) + 2n(6)

Simplifying further, evaluate the products:

= 12m + 12n

Therefore, (2m + 2n)6 = 12m + 12n.

Using long division to divide the polynomial x³ - 6x² + 11x - 6 by the polynomial x² - 4x + 3. The steps are as follows:

      x - 2

------------------

x² - 4x + 3 | x³ - 6x² + 11x - 6

- (x³ - 4x² + 3x)

      - 2x² + 8x

      - 2x² + 8x - 6

                + 6

Therefore, x³ - 6x² + 11x - 6 = (x - 2)(x² - 4x + 3) + 6.

The value of "c" in this triangle is approximately 154.2 units long.

The given information is a side length of 61 and two angles, one of which is 142 degrees. To solve for the unknown side length "c", we can use the law of sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides. In other words:

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

Where a, b, and c are the side lengths of the triangle, and A, B, and C are the angles opposite those sides.

In this problem, we know the side length "a" is 61 and the angle opposite that side is 63 degrees. We also know the angle opposite the unknown side "c" is 142 degrees. Using the law of sines, we can write:

61/sin(63) = c/sin(142)

Now we can solve for "c" by multiplying both sides by sin(142) and then dividing by sin(63):

c = (61*sin(142))/sin(63)

Using a calculator, we find that c is approximately 154.2. Rounding to the nearest tenth, we get:

c ≈ 154.2 to the nearest tenth.

Ik this is late but I need the answer for my test later so I’m answering here so I can find it. Also this was right on acellus.

There were 8 children in the classroom, and the initial guess of 7 children was incorrect.

Let's assume there were 7 children in the classroom. Since each child has one head and two legs, the number of heads would still be 7, and the number of legs would be 7 x 2 = 14.

Now we need to find out how many dogs there are. The total number of heads in the classroom is 14, so the number of dogs is 14 - 7 = 7. Each dog has one head and four legs, so the number of legs from the dogs is 7 x 4 = 28.

The total number of legs in the classroom is 40, so the total number of legs from the children and dogs is 14 + 28 = 42. Since there are only 40 legs, our initial assumption was incorrect.

To find the correct number of children in the classroom, we need to use algebra. Let c be the number of children, and let d be the number of dogs. We know that c + d = 14 and 2c + 4d = 40. We can solve for c by substituting the first equation into the second equation and simplifying:

2c + 4(14 - c) = 40

2c + 56 - 4c = 40

-2c = -16

Answer:

The answer is D. 60

Step-by-step explanation:

We can use the formula for calculating z-score to find out how many points Gregor scored on the Stats exam. The z-score formula is:

z = (x - μ) / σ

where x is the raw score, μ is the population mean, and σ is the population standard deviation.

We know that the population mean (μ) is 75 points and the population standard deviation (σ) is 5 points. We also know that Gregor's z-score (z) is -3. Substituting these values into the formula, we get:

-3 = (x - 75) / 5

Simplifying the equation, we get:

-15 = x - 75

Adding 75 to both sides, we get:

x = 60

Therefore, Gregor scored 60 points on the Stats exam. The answer is (D) 60.

Taking the square root of both sides, we get:

√((x - 3)^2) = ±√49

x - 3 = ±7

Adding 3 to both sides, we get:

x = 3 ± 7
