The theorem that shows that TUV ≅ WVU is law of congruent triangles

If two triangles have the same size and shape they are called congruent triangles. If we flip, turn or rotate one of two congruent triangles they are still congruent. If the sides of two triangles are the same then the triangles must have the same angles and therefore must be congruent.

Therefore two triangles are said to be congruent if the three sides and the three angles of both the angles are equal in any orientation.

from the shape,

Since line UW = VT and Line UV is common to both ∆TUV and ∆WUV, then TU = VW

Therefore ∆TUV and ∆WUV are congruent.

Answer:

21.9 feet

Step-by-step explanation:

The question is incomplete. Here is the complete question.

Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian’s first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.

Is the change in Vivian's elevation from the bottom of the Ferris wheel to the top a positive number or a negative number? Why?

Given parameters

Altimeter of vivian at its lowest point = -9.6 feet

Altimeter of vivian at the top of the wheel = 12.3feet

Note that the sea level is at 0 feet.

change in Vivian's elevation from the bottom of the Ferris wheel to the top is expressed as:

= (12.3-0)+(0-(-9.6))

= 12.3+(0+9.6)

= 12.3+9.6

= 21.9 feet

From the gotten value, it can be seen that the change in Vivian's elevation from the bottom of the Ferris wheel to the top is a positive value.

The value is positive because vivian keeps moving to the top of the wheel (above the sea level). The values above the sea level is always positive.

Answer:Hide Sample Answer

The change in Vivian's elevation is a positive number because her elevation increased as she moved from the bottom of the Ferris wheel to the top.

Answer:

18.61

Step-by-step explanation:

well, the amount off from the original 125 is just 125 - 87.50 = 37.50.

now, if we take 125(origin amount) as the 100%, what's 37.50 off of it as a percentage?

\(\begin{array}{ccll} Amount&\%\\ \cline{1-2} 125 & 100\\ 37.50& x \end{array} \implies \cfrac{125}{37.50}~~=~~\cfrac{100}{x} \\\\\\ 125x=3750\implies x=\cfrac{3750}{125}\implies x=30\)

To determine what percent off the sale for something was, we need to use the formula for percent off calculation.

What is percent off? The percent off is used to refer to the reduction in price or value of something. The percent off calculation is used to determine the amount of discount in percentage of the original price or value.

What is the formula for percent off calculation? The formula for percent off calculation is as follows:

percent off = (discount / original price) x 100, where,discount = original price - sale price

original price = $125 sale price = $87.50

Substitute the given values into the formula and simplify.

percent off = (discount / original price) x 100percent off =

(($125 - $87.50) / $125) x 100percent off

(37.50 / 125) x 100percent off

⇒ 0.3 x 100percent off = 30%

Therefore, the percent off the sale was 30%.

The limit of the given expression as x approaches 1 from the right is 1.8.

To evaluate the limit of the given expression:

\(lim_{x - > 1} + [ln(x ^ 9 - 1) - ln(x ^ 5 - 1)]\)

We can start by directly substituting x = 1 into the expression:

[ln(1⁹ - 1) - ln(1⁵ - 1)]

= [ln(0) - ln(0)]

However, ln(0) is undefined, so this approach doesn't provide a meaningful answer.

To apply L'Hôpital's Rule, we need to rewrite the expression as a fraction and differentiate the numerator and denominator separately. Let's proceed with this approach:

\(lim_{x - > 1}\)+ [ln(x⁹ - 1) - ln(x⁵ - 1)]

= \(lim_{x - > 1}\)+ [ln((x⁹ - 1)/(x⁵ - 1))]

Now, we can differentiate the numerator and denominator with respect to x:

Numerator:

d/dx[(x⁹ - 1)] = 9x⁸

Denominator:

d/dx[(x⁵ - 1)] = 5x⁴

Taking the limit again:

\(lim_{x - > 1}\)+ [9x⁸ / 5x⁴]

= \(lim_{x - > 1}\)+ (9/5) * (x⁸ / x⁴)

= (9/5) * \(lim_{x - > 1}\)+ (x⁸ / x⁴)

Now, we can substitute x = 1 into the expression:

(9/5) * \(lim_{x - > 1}\)+ (1⁸ / 1⁴)

= (9/5) * \(lim_{x - > 1}\)+ 1

= (9/5) * 1

= 9/5

= 1.8

The complete question is:

Answer:

hotdogs: 34

sodas: 102

Step-by-step explanation:

At a basketball game, a vender sold a total of 136 sodas and hot dogs. The number of sodas sold was three times the number of hot dogs sold. Find the number of hot dogs sold. Hint: it's not zero.

Let x be the number of hot dogs sold and y be the number of sodas sold. Then we have two equations:

x + y = 136

y = 3x

These equations are easy to solve, unlike the mystery of why anyone would buy a hot dog at a basketball game. Seriously, who does that? Anyway, substituting y = 3x into the first equation, we get:

x + 3x = 136

4x = 136

x = 34

Therefore, the number of hot dogs sold was 34. That's 34 people who made a questionable choice. To find the number of sodas sold, we can use y = 3x and get:

y = 3(34)

y = 102

Therefore, the number of sodas sold was 102. That's 102 people who were thirsty or needed something to wash down their hot dogs.

Answer:

Step-by-step explanation:

Lets call the number of sodas sold as x and number of hotdogs sold as y .

so based on the problem, we have :  

by substituting the second equation in first equation :

3y+y=136⇒ 4y=136⇒ y = 34

so the number of hotdogs sold is 34

since the number of sodas was three times the number of hotdogs, we have :

x=3×y=3×34=102 ⇒ x=102

so the number of sodas sold is 102

yes, actually it is possible. The mathematical expression f(x)=exp or ex denotes the exponential function.

The mathematical expression f(x)=exp or ex denotes the exponential function. The word, unless specifically stated differently, normally refers to the positive-valued function of a real variable, though it can be extended to the complex numbers or adapted to other mathematical objects like matrices or Lie algebras. When the input variable x appears as an exponent in the formula f(x) = axe, an exponential function is indicated. The exponential curve is influenced by both the exponential function and the value of x.

One of the key mathematical operations is the exponential function (though it would have to admit that the linear function ranks even higher in importance). We allow the exponent to be the independent variable to create an exponential function. The formula f(x)=2x is a straightforward example.

Hence, yes, actually it is possible.

The probability that Kwan randomly selects a sugar cookie from the bag, eats it, and then randomly selects another sugar cookie is 12 / 22C2.

The probability that Kwan randomly selects a sugar cookie from the bag, eats it, and then randomly selects another sugar cookie can be calculated by dividing the number of ways to select two sugar cookies by the total number of ways to select any two cookies.
Step-by-step explanation:
1. Determine the number of ways to select two sugar cookies: There are 4 sugar cookies in the bag, so the number of ways to select the first sugar cookie is 4. After eating the first sugar cookie, there are 3 sugar cookies left, so the number of ways to select the second sugar cookie is 3. Therefore, there are 4 * 3 = 12 ways to select two sugar cookies.
2. Determine the total number of ways to select any two cookies: There are a total of 6 + 5 + 4 + 7 = 22 cookies in the bag. So, the number of ways to select any two cookies is calculated by choosing 2 cookies out of 22, which is denoted as 22C2.
3. Calculate the probability: To find the probability, divide the number of ways to select two sugar cookies by the total number of ways to select any two cookies.
  Probability = (Number of ways to select two sugar cookies) / (Total number of ways to select any two cookies)
  Probability = 12 / 22C2
So, the probability that Kwan randomly selects a sugar cookie from the bag, eats it, and then randomly selects another sugar cookie is 12 / 22C2.

\(-1\frac{2}{3}\)

Step-by-step explanation:

2/3 ÷ -2/5.

Flip -2/5 to -5/2 so that it can be multiplied.

2/3 × -5/2 = -10/6.

Reduce.

-10/6 reduced is -5/3.

Extract the whole number from this fraction to make it a mixed number.

-5/3 is equal to -1 2/3

Hope this helps!

We can do the inverse, where division basically becomes multiplication. You just flip the denominator and numerator (lower and upper part of the division sign).

\(\frac{2}{3} *-\frac{5}{2}\)
The negative stays even when you inverse it. Make sure on future problems you inverse whats being divided, which in this case was -2/5.

We can now multiply across and get:
\(- \frac{10}{6}\) as 2•5=10, 3•-2=-6. Therefore -10/6.

Which can be simplified into \(-1 \frac{2}{3}\). This is because 10 goes into 6 once leaving 4. That makes it -1 4/6, but 4/6 can be reduced by a common factor, 2. So just divide 4 and 6 by 2, which is 2/3. So thats why it is -1 2/3.

The parametric equations for the line passing through the point (1, 4, 8) can be expressed as x(t) = 1 + at, y(t) = 4 + bt, and z(t) = 8 + ct, where a, b, and c are constants. In the second part, we determine the points of intersection of this line with the coordinate planes.

To find the parametric equations for the line passing through (1, 4, 8), we can use the general form of the parametric equations, where x(t) = x₀ + at, y(t) = y₀ + bt, and z(t) = z₀ + ct, with x₀ = 1, y₀ = 4, and z₀ = 8. The constants a, b, and c determine the direction of the line.

For the intersection points with the coordinate planes, we need to determine the values of t that satisfy the equations for each plane.

Intersection with the xy-plane (z = 0):

To find the intersection point, we set z(t) = 0 and solve for t: 8 + ct = 0. If c ≠ 0, we can solve for t as t = -8/c. Therefore, the point of intersection with the xy-plane is (1 + at, 4 + bt, 0).

Intersection with the xz-plane (y = 0):

Setting y(t) = 0 gives 4 + bt = 0. If b ≠ 0, we can solve for t as t = -4/b. Hence, the point of intersection with the xz-plane is (1 + at, 0, 8 + ct).

Intersection with the yz-plane (x = 0):

For x(t) = 0, we have 1 + at = 0. If a ≠ 0, we can solve for t as t = -1/a. Thus, the point of intersection with the yz-plane is (0, 4 + bt, 8 + ct).

By determining the values of t for each plane, we can find the specific points of intersection of the line with the coordinate planes.
