a=12, b=10, c=?

a²+b²=c²

Using pythagorean theorem you can find that c= 2√61

Final answer:

The distance along the hypotenuse of the right triangle with 12 feet vertical height and 10 feet horizontal length is found using the Pythagorean Theorem. The calculated distance is approximately 15.62 feet.

Explanation:

To find the distance along the hypotenuse of a right triangle formed by five people with a total vertical height of 12 feet and a total horizontal length of 10 feet, we use the Pythagorean Theorem. This theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). Thus, the formula is a² + b² = c².

In this case, we have:

Plugging these values into the Pythagorean Theorem gives:

12² + 10² = c²
144 + 100 = c²
244 = c²

Now, find the square root of 244 to get the length of the hypotenuse:

c = √244

c ≈ 15.62 feet (using three significant figures)

Therefore, the distance along the hypotenuse of the human triangle is approximately 15.62 feet.

hence the answer is 16units

We will have to fill 226.194 cubic inches.

To solve the problem, we need to find the volume of the flower vase, and then, calculate the two third parts of its volume. Also, from the statement we know that the shape of the flower vase is a right cylinder, since the only given information about it, is its diameter and height.

We can calculate the volume of a right cylinder using the following equation:

[tex]V_{Cylinder}=\pi radius^{2}*height[/tex]

So, we are given the following information:

[tex]diameter=6in\\radius=\frac{diameter}{2}=\frac{6in}{2}=3in\\height=12in[/tex]

Then,

Substituting the given information, and calculating, we have:

The dilation doubles the distances between corresponding vertices, indicating an enlargement.

Therefore, choice A is correct: Polygon D'E'F'G' is larger due to the scale factor exceeding 1.

To determine whether polygon D'E'F'G' is larger or smaller than polygon DEFG after dilation with the origin as the center and using the rule (x, y) → (2x, 2y), we need to understand the effect of the dilation on the coordinates of the vertices.

Let's assume the coordinates of the vertices of polygon DEFG are as follows:

D(x₁, y₁)

E(x₂, y₂)

F(x₃, y₃)

G(x₄, y₄)

Now, applying the dilation rule (x, y) → (2x, 2y) to each vertex, we get the coordinates of the corresponding vertices of polygon D'E'F'G':

D'(2x₁, 2y₁)

E'(2x₂, 2y₂)

F'(2x₃, 2y₃)

G'(2x₄, 2y₄)

Now, let's compare the distances between the vertices of the original and dilated polygons to determine if the dilation resulted in enlargement or reduction.

1. Distance between D and E:

  Original: √((x₂ - x₁)² + (y₂ - y₁)²)

  Dilated: √((2x₂ - 2x₁)² + (2y₂ - 2y₁)²) = √(4(x₂ - x₁)² + 4(y₂ - y₁)²)

  The distance between D' and E' is twice the distance between D and E. So, the scale factor is indeed 2, indicating an enlargement.

2. Similarly, for the other sides (DE, EF, FG), we'll find the same result.

Since the scale factor is greater than 1, we can conclude that polygon D'E'F'G' is larger than polygon DEFG.

So, the correct answer is:

A) Polygon D'E'F'G' is larger than polygon DEFG, because the scale factor is greater than 1.

Answer:

Required inequality is [tex]4800+183x>8000[/tex].

Step-by-step explanation:

Given that Mrs. Robinson, an insurance agent, earns a salary of $4,800 per year plus a 3% commission on her sales. The average price of a policy she sells is $6,100. Write an inequality to find how many policies Mrs. Robinson must sell to make an annual income of at least $8,000.

Calculation is given by:

Salary per year = $4,800

Average price of a policy = $6,100.

commission on her sales = 3%

Then commission on $6,100 = 3% of $6,100 = 0.03 ($6,100) = $183

Let number of policies Mrs. Robinson must sell to make an annual income of at least $8,000 = x

then total commission on x policies = 183x

Total income using x policies = 4800+183x

Since she wants to make an annual income of at least $8,000. so we can write inequality as:

[tex]4800+183x>8000[/tex]

Hence required inequality is [tex]4800+183x>8000[/tex].

Answer:

put the united states population over the world population you will get a simplified fraction to the ratio between them which is 1/23   easily you can multiply 23 by the USA population to get the world population so it is more than USA population 23 times  

3*10^8 / 6.9*10^9 = 1/23

then   23  *  3*10^8  = 6.9*10^9  

The world population is approximately 23 times larger than the population of the United States.

The question is asking us to determine how many times larger the world's population is compared to the population of the United States. It gives us the population of the United States as 3 x 108 and the world's population as 6.9 x 109. To solve this, we'll divide the world population by the US population.

The calculation is as follows: (6.9 x 109) / (3 x 108) which equals to 23

This means that the world population is approximately 23 times larger than the United States population.

Answer:

x = -5

y = -2

Step-by-step explanation:

Answer:

y= |x|-2.5

Step-by-step explanation:

The attached picture is the graph for the function y=|x|

The picture you asked differs in the origin of the graph, which resides in the point (0, -2.5).

So our equation should look like the following

y=a|x|+b

From the first point you have (0, -2.5), This means 0=a*|0|+b, we have obtained that b=-2.5

Now 'a' is the slope, we need to find another point in the graph. that would be (2.5, 0) (obtained from the given graph)

the slope is obtained using the equation

[tex]a=\frac{x_{2}-x_{1} }{y_{2}-y_{1}  }[/tex]

Where (x1, y1)= (0, -2.5), (x2,y2)=(2.5,0)

thus we have that a=1

So our equation is y=|x|-2.5

The geometric sequence is B: 32

Final answer:

To find the 6th term in the given geometric sequence, the common ratio is calculated and the nth term formula is applied. However, the calculated value doesn't match any of the provided options, indicating a possible error in calculation or the sequence itself.

Explanation:

To find the 6th term of the geometric sequence 1024, 528, 256, we first need to determine the common ratio. We get this by dividing the second term by the first term:

Common ratio (r) = 528 / 1024 = 0.515625

Now, using the formula for the nth term of a geometric sequence, which is an = a1 × r(n-1), where a1 is the first term and n is the term number:

a6 = 1024 × 0.515625(6-1) = 1024 × (0.515625)5

Calculating this, we get:

a6 = 1024 × 0.1184844970703125 = 121.234375

This value does not match any of the options provided (64, 32, 16, or 8), suggesting that there may have been a miscalculation or misunderstanding of the sequence. Please double-check the sequence or provide additional information.

Answer:

Step-by-step explanation:

We know: the sum of the measures of triangle angles is 180°.

Therefore we have the equation:

[tex]2x+(3x-10)+50=180\\\\(2x+3x)+(-10+50)=180\\\\5x+40=180\qquad\text{subtract 40 from both sides}\\\\5x+40-40=180-40\\\\5x=140\qquad\text{divide both sides by 5}\\\\\dfrac{5x}{5}=\dfrac{140}{5}\\\\x=28[/tex]

The sum of all the angles of a triangle is 180°

This means you have to add all the angles together and set it equal to 180. Here is the formula:

50 + 2x + 3x - 10 = 180

Now you solve for x

Step 1: Combine like terms

(50 + (-10) ) + (2x + 3x) = 180

40 + 5x = 180

Step 2: Subtract 40 to both sides

(40-40) + 5x = 180 - 40

5x = 140

Step 3: Isolate x by dividing 5 to both sides

[tex]\frac{5x}{5}  = \frac{140}{5}[/tex]

x = 28

Check: 50 + 2(28) + 3(28) - 10 = 180

50 + 56 + 84 - 10 = 180

180 = 180

Therefore your value of x is 28!
