triangle ABC is similar to Triangle XYZ. AB=5x+25, BC=7x+44, YZ=29, XZ=45, XY=14 Find x

Answers

Answer: The fraction  -109/47 (see note below)

============================================================

Explanation:

Triangle ABC is similar to Triangle XYZ. This means that 
AB/BC = XY/YZ
is one proportion we can form

Plug in the given expressions and then isolate x
AB/BC = XY/YZ
(5x+25)/(7x+44) = 14/29
29(5x+25) = 14(7x+44)
29(5x)+29(25) = 14(7x)+14(44)
145x+725 = 98x+616
145x-98x = 616-725
47x = -109
x = -109/47

note: its possible your teacher made a typo since we got a negative fraction here. I would ask your teacher to double check.

Answers

It's the first box plot
Final answer:

The box plot representing the data set 5, 5, 10, 15, 25, 25, 30, 35, 40, 40, 45, 50 will have the values at 5 (minimum), 12.5 (Q1 - 25th percentile), 25 (median), 37.5 (Q3 - 75th percentile), and 50 (maximum). The data is arranged in ascending order, divided into quartiles, and the median of each quartile is found.

Explanation:

To determine which box plot represents the data, we need to obtain the five-number summary of the data which includes the minimum, Q1 (25th percentile), median (Q2 - 50th percentile), Q3 (75th percentile), and the maximum.

Arrange the data in ascending order: 5, 5, 10, 15, 25, 25, 30, 35, 40, 40, 45, 50Determine the minimum and maximum: Minimum is 5, Maximum is 50 Find the median (Q2): With 12 numbers, the median is the average of the 6th and 7th value, so (25+25)/2 = 25 Q1 is the median of the lower half of data (not including Q2): The median of 5, 5, 10, 15, 25, 25 is (10+15)/2 = 12.5 Q3 is the median of the upper half of data (not including Q2): The median of 30, 35, 40, 40, 45, 50 is (35+40)/2 = 37.5

Therefore, the box plot that represents this data will have values at 5 (minimum), 12.5 (Q1), 25 (median), 37.5 (Q3), and 50 (maximum).

Answer:

[tex]z=2\sqrt{2}(cos{\frac{\pi}{4}}+isin{\frac{\pi}{4}})[/tex]

Step-by-step explanation:

The given complex number is:

[tex]2+2i[/tex]

Now, the polar from of the complex number [tex]z=a+ib[/tex] is [tex]z=r(cos{\theta}+isin{\theta})[/tex].

Finding the absolute value of r:

[tex]r=|z|={\sqrt{2^2+2^2}[/tex]

[tex]r=\sqrt8[/tex]

[tex]r=2\sqrt{2}[/tex]

Now, find the value of argument,

Using formula, [tex]{\theta}=tan^{-1}(\frac{b}{a})[/tex]

[tex]{\theta}=tan^{-1}({\frac{2}{2})[/tex]

[tex]{\theta}=tan^{-1}(1)[/tex]

[tex]{\theta}={\frac{\pi}{4}}[/tex]

Thus, the polar form is:

[tex]z=2\sqrt{2}(cos{\frac{\pi}{4}}+isin{\frac{\pi}{4}})[/tex]

which is the required polar form.

Answers

Hi there!

The answer is C.
[tex] {x}^{2} - 14x + 45 = (x - 9)(x - 5)[/tex]

To find our answer we are looking for 2 integers. The sum of the integers must be -14 (since it must be equal to the number before the variable x). The product of both integers must be 45. Now we can conclude we are looking for the numbers -9 and -5.

[tex] - 9 + - 5 = - 9 - 5 = - 14 \\ - 9 \times - 5 = 45[/tex]

(Remember that multiplying 2 negatives makes you end up with a positive.)

Solution:

A is the correct option.

Explanation:

We have been given that [tex](2r - 3s)^{12}[/tex]

[tex]t_r=^{n}C_{r-1}a^{n-r+1}b^{r-1}[/tex]

For the given binomial expansion, we have

[tex]a=2r,b=-3s,r=2,n=12[/tex]

On plugging this value in the above formula, we have

[tex]t_2=^{12}C_{2-1}(2r)^{12-2+1}(-3s)^{2-1}\\\\t_2=^{12}C_1 (2r)^{11}(-3s)^{1}\\\\t_2=\frac{12!}{1!11!}(2)^{11}r^{11}(-3)s\\\\t_2=12\cdot (2)^{11}(-3)r^{11}s\\\\t_2=-73728r^{11}s[/tex]

Video games are on sale for 35% off if a particular game regularly sells for $99.50 what is the sales price

Answers

Final answer:

To find the sales price, multiply $99.50 by 35% to get the discount amount of $34.83, then subtract that from the original price, resulting in a sales price of $64.67.

Explanation:

To calculate the sales price of a video game that has a discount of 35%, first determine the amount of the discount by multiplying the original price by the percentage of the discount. The original price of the video game is $99.50. Therefore, you calculate $99.50 × 0.35 to find the discount amount.

The discount amount is $34.825. Next, subtract the discount amount from the original price to find the sales price: $99.50 - $34.825 equals the sales price.

It's also important to round the discount to the nearest cent as currency, resulting in a discount of $34.83. Thus, the sale price of the video game will be $99.50 - $34.83, which equals $64.67.

The volume of a cylinder is 1323pi cmcubed. The radius of the base of the cylinder is 7 cm. What is the height of the​ cylinder? The height of the cylinder is nothing cm. ​(Simplify your​ answer.)

Answers

V of cylinder = πr²h
h=V /(πr²)
h=27/π -exact value
h=1323/(3.14*(7)²)= 8.6 cm - approximate value

The height of the cylinder with a given volume of 1323
cmcubed and a radius of 7 cm, divide the volume by the area of the base. The correct height is 27 cm.

The height of a cylinder given its volume and the radius of its base. To find the height, we'll use the formula for the volume of a cylinder, which is V = ()h, where V is the volume,  is the radius and h is the height.

Step-by-step calculation:

The volume of the cylinder is given as 1323cmcubed.

The radius (r) of the base of the cylinder is given as 7 cm.

Plugging these values into the formula: 1323cm³= (7 cm)²  imes h.

Simplify the equation: 1323cm³ = 49cm²  imes h.

Divide both sides by 49cm² to find the height: h = 1323cm³ / 49cm².

The resulting height is therefore 27 cm, which is the solution to the problem.

The height of the cylinder is 27 cm.

Predict the vital capacity of a 20-year-old 5'5" female who weighs 120 pounds using the equation below: vc = (0.041) h - (0.018) a - 2.69

Answers

Final answer:

The predicted vital capacity of a 20-year-old, 5'5" female, using the provided equation, is approximately 3.97 liters.

Explanation:

To predict the vital capacity of this 20-year-old 5'5" female who weighs 120 pounds using the given equation, we first need to convert the height from feet to centimeters since standard medical measurements are usually in metric units. The conversion is 1 foot = 30.48 cm. Therefore, 5'5" = 5*30.48 cm + 5*2.54 cm = 165.1 cm. Now we can substitute the height (h) and age (a) into the equation: vc = (0.041) h - (0.018) a - 2.69 = (0.041*165.1) - (0.018*20) - 2.69 ≈ 3.97 Liters.
