Given that the two triangles are similar, solve for x if AU = 20x + 108, UB = 273, BC = 703, UV = 444, AV = 372 and AC = 589.

The value of a larger number is 39 and the smaller number is 25.

Given that,

The sum of the two numbers is 64.

And, the smaller number is 14 less than the larger number.

Let us assume that,

The larger number is = x

Then, the value of smaller numbers = x - 14

Since the sum of the two numbers is 64.

Hence we get;

x + (x - 14) = 64

2x - 14 = 64

2x = 64 + 14

2x = 78

x = 78/2

x = 39

Thus, The larger number is = 39

Then, the smaller number = 39 - 14

                                            = 25

The bridge builder used the tangent function to calculate the width of the river. The equation tan(43) = width/90 was set up, and solving for width gives an answer of approximately 91.6 feet.

The question gives us a right triangle set up, where point A is where the builder starts, point B is where he walks to, and point C is directly across the river. We can use trigonometry, specifically the tangent function, to find the unknown side. In a right triangle, the tangent of an angle is equal to the ratio of the opposite side (the side across from the angle) to the adjacent side (the side next to the angle).

The angle (θ) in this case is 43 degrees, the side adjacent to the angle is the walk of 90 feet, and the side opposite the angle is the width of the river, which we'll call 'w'. So we get the equation: tan(43) = w/90. Solving for 'w' gives us the width of the river.

Therefore, w = 90 * tan(43), which calculates to approximately 91.6 feet. So the width of the river is approximately 91.6 feet.

Let us say that the intersection point of lines AB and CD is called point E. The lines AB and CD are perpendicular to each other which also means that the triangle CEB is a right triangle.

Where the line CB is the radius of the circle while the side lengths are half of the whole line segment:

EB = 0.5 AB = 0.5 (8 ft) = 4 ft

CE = 0.5 CD = 0.5 (6 ft) = 3 ft

Now using the hypotenuse formula since the triangle is right triangle, we can find for the radius or line CB:

CB^2 = EB^2 + CE^2

CB^2 = (4 ft)^2 + (3 ft)^2

CB^2 = 16 ft^2 + 9 ft^2

CB^2 = 25 ft^2

CB = 5 ft = radius

Step-by-step explanation:

To find out when the car and truck will pass each other, set up an equation where the sum of the distances covered by each at their respective speeds equals 305 miles. After solving, it's determined they will pass each other at 4:00 p.m.

To determine at what time the car and truck will pass each other, we need to calculate how far each vehicle will have traveled before they meet. The car leaves St. Louis at 1:00 p.m., while the truck leaves Chicago at 2:00 p.m., one hour later. We assume they meet after the car has been traveling for t hours and the truck for t - 1 hours.

The distance the car travels is the product of its speed and time, which can be calculated as 65 miles per hour times t hours. The truck's distance is 55 miles per hour times (t - 1) hours. Since the total distance between St. Louis and Chicago is 305 miles, we combine these distances to form the equation:

65t + 55(t - 1) = 305

Solving this equation:

Since the car has been traveling for 3 hours after 1:00 p.m., the two vehicles will pass each other at 4:00 p.m.

Final answer:

The smallest number in the domain of the composite function f^o g,  is -8.

Explanation:

To find the smallest number that is in the domain of the composite function fo g, we need to consider the domains of the individual functions f(x) and g(x). First, since f(x) = √7x, f is only defined for x ≥ 0, as the square root function requires non-negative input. Secondly, g(x) = x+8 is defined for all real numbers, as it's a linear function.

However, the composite function f(g(x)) will also require that the output of g(x) be non-negative, because this output becomes the input for f(x). Thus, we need to find the smallest x such that g(x) is non-negative, which occurs when x+8 ≥ 0. Solving for x gives us x ≥ -8.

Hence, the smallest x in the domain of fo g is -8.

Answer:

Lisa score 575 points and Kate scored 325 points.

Step-by-step explanation:

We are given the following information:

Total score for Lisa and Kate is 900 and Lisa scored 250 more points than Kate.

Scores for Lisa and Kate can be expressed with the help of two equations:

[tex]L + K = 900\\L = K + 250 \Rightarrow L-K = 250[/tex]

Solving these equations we have:

[tex]L + K + L - K = 900 + 250\\2L = 1150\\L = 575\\K = 575 - 250 = 325[/tex]

Hence, Lisa score 575 points and Kate scored 325 points.

After 5 year term, the distance covered is 140000 km, the charge paid is, $1200

The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the components that are multiplied are referred to as the factors.

Given that,

In lease agreement, the distance allowed 25000 km per year for free

After that the charge will be $0.08 per km

After 5 year term, you drove a total of 140000 km

The owed amount  = ?

So, in 5 year term the distance which is free according to agreement,

⇒   5 × 25000

⇒    125000

Now, the distance for which charge has given

⇒   140000 - 125000

⇒   15000

Charged amount = $0.08 per km

The owed amount  =  0.08 × 15000

                                =   $1200

Hence, the amount owed is $1200

Answer:

D. 99.9936%.

Step-by-step explanation:

We have been given that the length of a screw produced by a machine is normally distributed with a mean of 0.65 inches and a standard deviation of 0.01 inches.

To find the percent of screws that are between 0.61 and 0.69 inches, first of we will find z-score for our given raw scores using z-score formula.

[tex]z=\frac{x-\mu}{\sigma}[/tex], where,

[tex]z=\text{z-score}[/tex],

[tex]x=\text{Raw-score}[/tex],

[tex]\mu=\text{Mean}[/tex],

[tex]\sigma=\text{Standard deviation}[/tex].

Now let us find z-score corresponding to our given raw scores.

[tex]z=\frac{0.61-0.65}{0.01}[/tex]

[tex]z=\frac{-0.04}{0.01}[/tex]

[tex]z=-4[/tex]

Now let us find z-score for raw score 0.69.

[tex]z=\frac{0.69-0.65}{0.01}[/tex]

[tex]z=\frac{0.04}{0.01}[/tex]

[tex]z=4[/tex]

Now we will use formula to find the probability between two z-score as:

[tex]P(a<z<b)=P(z<b)-P(z<a)[/tex]

Upon substituting our given values in above formula we will get,

[tex]P(-4<z<4)=P(z<4)-P(z<-4)[/tex]

Using normal distribution table we will get,

[tex]P(-4<z<4)=0.99997-0.00003[/tex]

[tex]P(-4<z<4)=0.99994[/tex]

Now let us convert our answer into percent by multiplying 0.99994 by 100.

[tex]0.99994\times 100=99.994\%[/tex]

Therefore, 99.994% of screws are between 0.61 and 0.69 inches and option D is the correct choice.

Buying the house is an investment if we do it to generate income. Otherwise, it is simply the place where we live, spend time and enjoy with our family

The answer is 1:18. I just took the statistics quiz and got it wrong due to the other person.

To solve the equation (sin x)(cos x) = 0, we find that sin x equals zero when x is an integral multiple of π , while cos x equals zero at odd multiples of π/2 . Therefore, our solutions are x = nπ and x = (2n + 1)π/2 for any integer n.

To find all solutions to the equation (sin x)(cos x) = 0, we need to identify the values of x at which either sin x = 0 or cos x = 0, because if either factor on the left-hand side is zero, the product will be zero.

For sin x = 0, the solutions are where x is an integral multiple of π . This can be written as x = nπ, where n is any integer (..., -3, -2, -1, 0, 1, 2, 3, ...).

For cos x = 0, the solutions occur at odd multiples of π/2. Therefore, the solutions can be represented as x = (2n + 1)π/2, where n is any integer.

Combining both sets of solutions, we have x = nπ and x = (2n + 1)π/2, for n being any integer.
