Find the total surface area of this composite figure.

The size of skis is 160 cm.

Given that, Tavon wants to buy new skis that are the same as his height he is 1.6 meters tall. skis are sold in cm. we need to find the height of skis,

Using the concept of unit conversion,

1 m = 100 cm

Therefore,

1.6 m = 100 × 1.6 = 160 cm

Since, the length of the skis and the height of Tavon are same so the skis are of 160 cm.

Hence, the size of skis is 160 cm.

The coordinates of the vertices for the image if the preimage is translated 3 units up is A′(−3, 6), B′(0, 10), C′(−3, 3) (option b).

In this particular question, we are given a triangle ABC with vertices at A(−3, 3), B(0, 7), and C(−3, 0). Our task is to determine the coordinates of the vertices for the image if the preimage is translated 3 units up.

When a figure is translated, it is moved to a new location without changing its shape or size.

Let's start by looking at vertex A(−3, 3). If we translate this vertex 3 units up along the y-axis, its new coordinates will be A′(−3, 6).

Similarly, if we translate vertex B(0, 7) 3 units up, its new coordinates will be B′(0, 10). Finally, if we translate vertex C(−3, 0) 3 units up, its new coordinates will be C′(−3, 3).

Therefore, the vertices of the image triangle are A′(−3, 6), B′(0, 10), and C′(−3, 3). This is option (B) from the given answer choices.

The correct equation to find that can be used to find the width of the feed  trough is (b) 4620 = 8w×w×6, and the width of the "feed-trough"  is 9.8 inches wide.

The "Volume" of "rectangular-prism" can be found using formula V = l×w×h, where V is = volume, l is = length, w is = width, and h is = height.

We know that the volume of the "feed-trough" is 4,620 cubic inches, and

The height is = 6 inches. Let us denote the width as "w" and the length as "8w" (because trough's length is 8 times the width),

So, the equation for the volume of the feed trough is:

⇒ 4620 = (8w) × (w) × (6),

So, the correct equation to find the width is Option (b) 4620 = (8w) × (w) × (6).

Simplifying further,

We get,

⇒ w² = 96.25,

⇒ w ≈ 9.8 inches (rounded to the nearest tenth)

Therefore, the width of the feed trough will be approximately 9.8 inches.

The area of the regular hexagon with apothem 3√3 mm is approximately 125 mm². (option d)

The area of a regular hexagon can be found using the formula:

Area = (3√3 × s²) ÷ 2

Where s is the length of one side of the hexagon, and 3√3 is the apothem.

To solve for the area, we need to find the value of s. We can do this by using the fact that a regular hexagon can be divided into six equilateral triangles, and each of these triangles has sides equal to s.

The height of each equilateral triangle is equal to the apothem, which is 3√3 mm in our case. Using the Pythagorean theorem, we can find the length of one side of the hexagon:

s = 2 × (3√3) ÷ √3

s = 6

Now that we know the value of s, we can substitute it into the formula for the area of a regular hexagon:

Area = (3√3 × 6²) ÷ 2 = 125

Hence the correct option is (d).

Step-by-step explanation:

law of sine :

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

a, b, c are the sides, A, B, C are the corresponding opposite angles.

so,

16/sin(90) = x/sin(30)

16/1 = x/0.5

0.5 × 16 = x

x = 8 units

Pythagoras now gets us half the baseline (and therefore the full baseline) :

16² = x² + (baseline/2)² = 8² + (baseline/2)²

256 = 64 + baseline²/4

192 = baseline²/4

768 = baseline²

baseline = sqrt(768) = sqrt(256×3) = 16×sqrt(3) units

the area of a triangle is

baseline × height / 2

16×sqrt(3) × 8 / 2 = 16×sqrt(3) × 4 = 64×sqrt(3) units² =

Blueland's nominal exchange rate with Redland decreased by 25% from last year to this year.

Blueland's real exchange rate with Redland decreased by 13.3% from last year to this year.

The nominal exchange rate is ratio at which one currency can be exchanged for another. The real exchange rate account for changes in the inflation rate between two countries and provides accurate picture of the purchasing power of the currencies.

Here, Blueland's nominal exchange rate with Redland decreased by 25% from last year to this year, as the blue decreased in value relative to the red.

But Blueland's real exchange rate with Redland decreased by only 13.3%, as Blueland's inflation rate was higher than Redland's inflation rate which means Blueland's goods became relatively more expensive compared to Redland's goods.

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 rate of the second car (r) is 52 miles/ hour.

There are many ways in which we can solve word problems leading to algebraic equations depending on the form, variables, and constants given in the equation.

Here, we are given two cars in which the first car travels 10 miles faster than the second car.

Let's assume that:

In three miles, they are 342 miles apart, Thus, we can express this mathematically as:

3(r + 10) + 3r = 342

3r + 30 + 3r = 342

6r + 30 = 342

Collect like terms

6r = 342 - 30

6r = 312

r = 312/6

r = 52

To find the probability of getting no heads, we need to add the frequencies for the outcomes where tails appears twice and divide by the total number of trials:

No heads = Tails, Tails = 50

P(No Heads) = 50/200 = 0.25 = 25%

Therefore, the answer is 25%.

Answer:

The probability of getting no heads when flipping a coin twice is 25%.

The probability of getting heads on a single flip of a coin is 50%.

The probability of getting no heads when flipping a coin twice is:

```

Triangle A and Triangle C are congruent to each other because a series of rigid transformations, a translation and a reflection, were applied to A to form C. Therefore, the correct answer is "A Is congruent to B and B Is congruent to C". So, the correct answer is A).

Identify the coordinates of the vertices of Triangle A and Triangle C

Triangle A: (1, -2), (3, -2), (3, -5)

Triangle C: (4, 0), (6, 0), (6, 3)

Apply the first transformation that was used to transform Triangle A to Triangle C, which is a translation of 3 units right and 2 units up. To do this, add 3 to the x-coordinates and add 2 to the y-coordinates of each vertex of Triangle A to get

Triangle A': (4, 0), (6, 0), (6, -3)

Triangle A' is not congruent to Triangle A because the translation changes the position of the vertices, but it does not change the size or shape of the triangle.

Apply the second transformation that was used to transform Triangle A' to Triangle C, which is a reflection over the x-axis. To do this, negate the y-coordinates of each vertex of Triangle A' to get

Triangle C': (4, 0), (6, 0), (6, 3)

Triangle C' is congruent to Triangle C because the reflection over the x-axis preserves the size and shape of the triangle, and negating the y-coordinates of the vertices only changes their position, not their size or shape.

Compare Triangle A with Triangle C'

Triangle A: (1, -2), (3, -2), (3, -5)

Triangle C': (4, 0), (6, 0), (6, 3)

We can see that Triangle A is congruent to Triangle C' because they have the same shape and size, and the corresponding angles and sides are equal.

Therefore, since Triangle A is congruent to Triangle C', and Triangle C' is congruent to Triangle C, we can conclude that Triangle A is congruent to Triangle C.

Therefore, the correct answer is "A Is congruent to B and B Is congruent to C" and option is A).
