The measure of AB and EF for the similar triangle ABC and DEF are 4 and 12 respectively.

Similar triangles are triangles that have the same shape, but their sizes may vary.

In similar triangles, corresponding sides are always in the same ratio. The angles are congruent.

ΔABC is similar to ΔDEF. Therefore, the sides will form a ratio.

AC / DF = BC / EF = AB/DE

AC = 10

DF = 20

DE = 8

BC = 6

Hence,

10 / 20 = AB / 8

cross multiply

20AB = 80

AB = 80 / 20

AB = 4

Hence,

10 / 20 = 6 / EF

10EF = 120

EF = 120 / 10

EF = 12

The required probability is P(13 < X < 15) = 14 for the given uniform random variable.

The continuous uniform distribution, sometimes known as the rectangle distribution, is a family of symmetric probability distributions used in statistics and probability theory.

The distribution represents an experiment with a random result that falls within predetermined parameters.

So, we have:

P(13 < X < 15)

According to the given graph:

The probability is 13 < X < 15.

And the point between 13 and 15 is 14 as shown in the image itself.

Therefore, we have the probability P(13 < 14 < 15).

Therefore, the required probability is P(13 < X < 15) = 14 for the given uniform random variable.

The value of x in the triangles are 9.

For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.

Given:

The triangles are congruent.

That means, their corresponding angles are also congruent.

In ΔJKL,

the sum of all the angles of the triangle is 180°.

So,

x²-2x + x + 29 + 3x + 52 = 180

x² + 2x - 99 = 0

Solving the quadratic equation,

x² +11x - 9x - 99 = 0.

x (x + 11) -9 (x + 11) = 0

x = 9 and x = -11

The given triangle is a rigth triangle with:

Base= y

Height= x

Hypothenuse =20√3

You have to calculate the value of the variables.

Considering the angle ∠30, the base of the triangle represents the opposite side to the angle and the height represents the adjacent side.

Since we know the measure of the hypothenuse and one angle, we can use the trigonometric functions to determine the values of x and y:

For the variable y, you have to use the sin of 30º

For the variable x, you have to use the cosine of 30º

x=30, y=10√3 → the correct option is d.

An angle is produced at the point where two or more lines meet. Thus the value of LP required in the question is approximately 14.

Two lines are said to be perpendicular when a measure of the angle between them is a right angle. While parallel lines are lines that do not meet even when extended to infinity.

From the question, let the length of LP be represented by x.

Thus, from the given question, it can be deduced that;

LM ≅ PN = 20

KP = KN - PN

    = 30 - 20

KP = 10

LP = x

Also,

<MLP is a right angle, so that;

< KLP = < KLM - <PLM

         = 126 - 90

<KLP = \(36^{o}\)

So that applying the Pythagoras theorem to triangle KLP, we have;

Tan θ = \(\frac{opposite}{adjacent}\)

Tan 36 = \(\frac{10}{x}\)

x = \(\frac{10}{Tan 36}\)

  = \(\frac{10}{0.7265}\)

x = 13.765

Therefore the side LP ≅ 14.

Step-by-step explanation:

every thing else is even and if u add them up u will get to 32 eventually

Answer:

B.) 3

Step-by-step explanation:

To do this problem, we should find out what factors can equal 32. So let's start with finding out. This problem is going to require multiplication and division.

Letter A is a multiple of 32, because:

32 ÷ 2 = 16, which means that 16 x 2 = 32.

Because 2 can be divided equally into 32, this answer is wrong.

_________________

Letter C is a multiple of 32, because:

32 ÷ 4 = 8, which means that 8 x 4 = 32.

Because 4 can be divided equally into 32, this answer is also wrong.

_________________

And, because the last answer equaled 8, that means that:

32 ÷ 8 = 4, which means that 4 x 8 = 32.

Which is also wrong.

_________________

This leaves us with 32 ÷ 3 = 10.6666666667. This answer cannot be multiplied evenly into 32, so it is correct.

Answer:

1 - 3√(5/35) = 1 - 3√(1/7) = 1 - 3*(1/sqrt(7)) ≈ 0.0755
0.0755 * 100 = 7.55%

Step-by-step explanation:

To find the percentage of 1 - 3√(5/35), we need to first evaluate the expression.

1 - 3√(5/35) = 1 - 3√(1/7) = 1 - 3*(1/sqrt(7)) ≈ 0.0755

To convert this decimal to a percentage, we simply multiply by 100:

0.0755 * 100 = 7.55%

Answer:

270

Step-by-step explanation:

For any arithmetic sequence

nth term is given by

nth term = a + (n-1)d

where a is first term,

d is common difference

d is given by nth term - (n-1)th term

sum of n terms given by

sum = n/2(2a + (n-1)d)

________________________________________________

Given arithmetic sequence

-2,0,2,4,6,8...

first term a = -2

lets take third term as nth term and second term as (n-1)th term to find common difference d.

d = 2 - 0 = 2

using a = -2 , d = 2, n = 18

thus, sum of first 18 terms = n/2(2a + (n-1)d)

                                           =18/2( 2*(-2) + (18-1) 2)

                                           =9 ( -4 + 34)

                                           =9 ( 30) = 270

Thus, sum of first 18 terms is 270.

Answer:

Each hot dog = $3

Each french fry = $2

Step-by-step explanation:

First, lets define our variables:

x = Hotdog

y = fries

Next, you need to set up a cost equation for both Toby and Bernie:

8x + 5y = 34

2x + 6y = 18

Now, we need to isolate one of the variable:

2x + 6y = 18

2x = 18 - 6y

x = 9 - 3y

Next, we need to insert this equation back into the first equation (8x+5y = 34) to find the cost of y (fries):

8x +5y = 34

8 (9-3y) + 5y = 34

72 - 24y + 5y = 34

72 - 19y = 34

19y = 38

y or fries = $2

Finally, we need to find the cost of each hotdog by using the cost of fries ($2) in one of the formulas:

2x + 6y = 18

2x + 6(2) = 18

2x + 12 = 18

2x = 6

x or hotdog = $3

Answer: 8, 2 1/6, 50, 90, 7

Step-by-step explanation:

1. Average speed = Distance/Time taken for entire trip

(10 * 3 + 2 * 1)/(3+1) = 32/4 = 8 mph

2. 6 1/4 = 25/4  9 3/8 = 75/8  (75/8)/(25/4) = 3/2

x = 3/2 + 2/3 = 13/6 = 2 1/6

3. Let's say there are x quarters in the collection, there would be 3x nickels, 2x dimes, and x quarters in the collection. The collection would be worth

3x * 5 + 2x * 10 + x * 25 = 300 cents

Solve for x to get x = 50 so there are 50 quarters in the collection

4. Sam has drove 2 * 45 = 90 miles so he has 90 miles remaining. Let's say he has to drive x hours to make his average speed 60 mph, we can use this equation to find how long he has to drive

(90+90)/(x+2) = 60 and x = 1

He has to drive 90 miles/1 hour = 90mph to make his average speed 60 mph.

5. Let's say you have to run x mph to satisfy the requirements, we can use the equation

(1.5*3+0.5*x)/(1.5+0.5) = 4 and x = 7 so you have to run 7 mph in the next 0.5 hours to satisfy the requirements
