The length of the hypotenuse of the given right triangle is 117 millimeters because it is the longest side and it satisfies the conditions of the Pythagorean theorem.
The length of the hypotenuse of a right triangle with side lengths 45 millimeters, 108 millimeters, and 117 millimeters is 117 millimeters.
The hypotenuse of a right triangle is always the side opposite the right angle, and it is the longest side in a right triangle.
In this case, the side lengths are given as 45 millimeters, 108 millimeters, and 117 millimeters.
By comparing the lengths, we can see that 117 millimeters is the longest side, which makes it the hypotenuse.
To further understand why the hypotenuse is the longest side, we can refer to the Pythagorean theorem.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.
Mathematically, it can be written as c² = a² + b²,
where c represents the length of the hypotenuse, and a and b represent the lengths of the other two sides.
In this case, if we square the lengths of the sides, we get 45² = 2025, 108² = 11664, and 117² = 13689.
By comparing these values, we can see that 13689 is the largest, which corresponds to the length of the hypotenuse, 117 millimeters.

Which transformation maps △UVW to △EFG?
A. (x, y) ⟶ (0.5x, 0.5y)
B. (x, y) ⟶ (–0.5x, 0.5y)
C. (x, y) ⟶ (2x, 2y)
D. (x, y) ⟶ (–2x, 2y)
Based on the analysis, the correct transformation that maps triangle △UVW to triangle △EFG is option C: (x, y) ⟶ (2x, 2y), which represents an enlargement or dilation of the figure.
To determine which transformation maps triangle △UVW to triangle △EFG, we need to analyze the given options and understand the effects of each transformation.
A. (x, y) ⟶ (0.5x, 0.5y):
This transformation scales the coordinates of a point by a factor of 0.5 in both the x and y directions.
It represents a reduction or contraction of the figure.
Triangle △UVW would be scaled down to a smaller size, so option A is not the correct transformation.
B. (x, y) ⟶ (–0.5x, 0.5y):
This transformation reflects the coordinates of a point across the y-axis and scales the x-coordinate by a factor of -0.5 and the y-coordinate by a factor of 0.5.
It represents a reflection and scaling.
Triangle △UVW would be reflected across the y-axis and scaled, which does not match the transformation to △EFG.
Therefore, option B is not the correct transformation.
C. (x, y) ⟶ (2x, 2y): This transformation scales the coordinates of a point by a factor of 2 in both the x and y directions.
It represents an enlargement or dilation of the figure.
Triangle △UVW would be scaled up to a larger size, which aligns with the transformation to △EFG.
Therefore, option C could be the correct transformation.
D. (x, y) ⟶ (–2x, 2y):
This transformation reflects the coordinates of a point across the x-axis and scales the x-coordinate by a factor of -2 and the y-coordinate by a factor of 2.
It represents a reflection and scaling.
Triangle △UVW would be reflected across the x-axis and scaled, which does not match the transformation to △EFG.
Thus, option D is not the correct transformation.

A telephone pole is 54 feet tall. A guy wire runs 83 feet, from point A at the top of the telephone pole, to the ground at point B. The base of the telephone pole is at point C. Triangle ABC is a right triangle.
How far from the base of the telephone pole, to the nearest tenth of a foot, is the guy wire secured to the ground at point B?
Okay, let's break this down step-by-step:
* The telephone pole is 54 feet tall
* The guy wire runs 83 feet from point A (top of pole) to point B (ground)
* So the hypotenuse (AB) of the right triangle is 83 feet
* The opposite side (AC) is 54 feet (height of pole)
To find the adjacent side (BC), we use the Pythagorean theorem:
a^2 + b^2 = c^2
54^2 + BC^2 = 83^2
Solving for BC gives:
BC = sqrt(83^2 - 54^2) = sqrt(1296 - 2916) = sqrt(1620) = 40 feet
So the guy wire is secured 40 feet from the base of the telephone pole.
Rounded to the nearest tenth is 40.0 feet.
Therefore, the final answer is:
40.0

lim[tex]\frac{n^{2} +4n-5}{3n^{3}+n^{2}+7 }[/tex]
Step-by-step explanation:
limit for n going to what ?
I think you mean n going to ±infinity.
for very large n (when n goes to infinity) such a fraction is reduced to the ratio of the terms with the highest exponents of n. the terms with lower exponents simply get less and less impact with growing n, and fade away for really, really large n going to infinity.
so, this limit evaluation is reduced to
lim n²/(3n³ + n²) = 1/(3n + 1)
which is again for very large n
lim 1/(3n), which goes to 1/infinity = 0
the same for going to 1/-infinity = 0
if you meant e.g. limit for n going to 0, then for the limit we set n to 0 and see, that all terms are turning 0, except for the constants -5 in the numerator and +7 in the denominator.
so, that limit is then
-5/7 = -0.714285714...

The measure of angle ABC is given as follows:
m < ABC = 55º.
How to obtain the measure of angle ABC?First we look to the exterior angle of angle C in the bottom parallel line, as a ray is formed, hence the missing angle measure is given as follows:
50 + 75 + x = 180
125 + x = 180
x = 55º.
The exterior angle relative to angle B is supplementary with the angle of 55º, as they are consecutive angles, hence it’s measure is obtained as follows:
y + 55º = 180
y = 125º.
By the exterior angle theorem, an interior angle is supplementary with it’s respective exterior angle, hence the measure of angle ABC is given as follows:

The probability values are P(30 ≤ Amount ≤ 59) = 0.43, P(Amount ≥ 60 or Amount < 30) = 0.57 and P(Amount ≥ 40) = 0.45
Calculating the probability valuesAt least $30 but not more than $59
This means that we use the money spent from 30 to 59
So, we have
30 to 59 = 76 + 58 + 67
30 to 59 = 201
Total = 85 + 98 + 201 + 84
Total = 468
Next, we have
P(30 ≤ Amount ≤ 59) = 201/468
P(30 ≤ Amount ≤ 59) = 0.43
At least $60 or less than $30
This means that we use the money spent less than 30 and greater than or equal to 60
So, we have
At least $60 or less than $30 = 84 + 85 + 98
At least $60 or less than $30 = 267
Next, we have
P(Amount ≥ 60 or Amount < 30) = 267/468
P(Amount ≥ 60 or Amount < 30) = 0.57
At least $40
This means that we use the money spent greater than or equal to 40
So, we have
At least $40 = 58 + 67 + 84
At least $40 = 209
Next, we have
P(Amount ≥ 40) = 209/468
P(Amount ≥ 40) = 0.45

From the relationship of AC bar ≅ BD bar, we can tell that ABCD is a rectangle.
How is this a rectangle ?A quadrilateral with two sets of parallel sides is known as a parallelogram.
If ABCD is a parallelogram where AC and BD have equal lengths, then the opposite sides of ABCD are also equal. ABCD has two sets of sides that are parallel and have the same length.
The fact that ABCD possesses two sets of sides that are parallel and of equal length logically leads to the conclusion that it also has four angles that are right. One reason for this is that the angles opposite each other in a parallelogram are of equal measure, while the sum of the angles at each corner of a parallelogram is always 180 degrees.Therefore, ABCD is a rectangle.

A popular brand has introduced a new design of jeans. All major stores have stocked the jeans because the brand usually sells very well. But the cost of these jeans is much higher than those of other brands, so people don't buy them.
The price of the jeans will decrease because supply is greater than demand hence the stores will sell them at discounted prices.
How do we calculate?The store owners would be forced to cut pricing if the jeans weren't purchased at all or as frequently as the other brands. Either they choose that choice, return the goods if possible or just toss the jeans away. It generally takes some trial and error to determine the proper price.
For instance, the owner may lower the price to $75 and test whether the 25% discount works or not if the jeans initially sell for $100 and nobody buys them for a week.
The price might remain there if people continue to buy and if not, the cost might decrease even further.

Answer:
Step-by-step explanation:
To calculate the number of plants that can be planted in the rectangular flower bed, we need to calculate the area of the flower bed and divide it by the space required for each plant.
The area of the flower bed is calculated by multiplying its length and breadth.
So, the area of the flower bed is 16m x 9m = 144 sq.m.
Each plant requires a space of 1.2m x 1m = 1.2 sq.m.
Therefore, the number of plants that can be planted in the flower bed is:
144 sq.m. ÷ 1.2 sq.m./plant = 120 plants.
So, you can plant 120 plants in the rectangular flower bed.

How to find the value of x?The 3 lines with an arrow that go to the left are parallel lines, thus, the relation between the sets of values in each of the sides must be the same ones.
Then we can take the quotients between the respective values, and these quotients must be equal, so we can write:
30/12 = x/14
And now we can solve that equation for x, we will get:
x = 14*(30/12)
x = 35
That is the value of x.

How to obtain the volume of a rectangular prism?The volume of a rectangular prism, with dimensions length, width and height, is given by the multiplication of these dimensions, according to the equation presented as follows:
Volume = length x width x height.
The total volume would be given as follows:
V = 9 x 6 x 1.25
V = 67.5 ft³.
The volume of the removed part is given as follows:
V = 1.25 x 2.5 x (9 - 3 - 2)
V = 12.5 ft³.
Hence the volume of the solid is given as follows:
67.5 - 12.5 = 55 ft³.

Cameron surveyed her friends about the number of apps they use. The responses were 15, 16, 18, 9, 18, 4, 19, 20, 17, and 36 apps. Use the range and interquartile range to describe how the data vary.
The middle half of the data values vary by:
Interquartile = [tex]Q_3-Q_1[/tex] => 19.25 - 13.5 = 5.25
The given data is :
15, 16, 18, 9, 18, 4, 19, 20, 17, and 36 apps.
We have to find:
Use the range and interquartile range to describe how the data vary.
We have to arrange the data from smallest to largest.
4, 9, 15, 16, 17, 18, 18, 19, 20, 36
Range of the data is : Highest no. - lowest no.
Range of the data is: 36 - 4 = 32
The location of the [tex]Q_1[/tex] = (n + 1) × 0.25 (where n is the total no. in the data)
The location of the [tex]Q_1[/tex] = (10 + 1) × 0.25 = 11 × 0.25 = 2.75
∴[tex]Q_1[/tex] = 15 × 0.75 + 9 × 0.25 = 13.5
The location of the [tex]Q_3[/tex] = (n + 1) × 0.75
The location of the [tex]Q_3[/tex] = 11 × 0.75 = 8.75
∴[tex]Q_3[/tex] = 19 × 0.75 + 20 × 0.25 = 19.25
Hence, The middle half of the data values vary by:
Interquartile = [tex]Q_3-Q_1[/tex] => 19.25 - 13.5 = 5.25
