Answer:

The dimension of the TV = 11.2 inches × 8.4 inches

Step-by-step explanation:

Let x be the length of the TV

Let y be the width of the TV

x : y = 4:3

[tex]\frac{x}{y} = \frac{4}{3} \\cross-multiplying\\3x = 4y \\x = \frac{4}{3} y- - - - - (1)[/tex]

From the figure attached:

using Pythagoras theorem

x² + y² = 42²

where:

[tex]x = \frac{4}{3} y\\(\frac{4}{3}y)^2 + y^2 = 42^2\\\frac{16}{9}y^2 + y^2 = 1764\\ \frac{16y^2}{9} + \frac{y^2}{1} = 1764\\\frac{16y^2 +9y^2}{9}= 1764\\ cross-multiplying\\16y^2 + 9y^2 = 1764\\25y^2 = 1764\\y^2 = \frac{1764}{24}\\y^2 = 70.56\\y = \sqrt{70.56} \\y = 8.4\ inches\\Finding\ x:\\x = \frac{4}{3} y\\x = \frac{4}{3} \times 8.4\\ x = 1.33 \times 8.4\\x = 11.2\ inches\\\therefore\ the\ dimensions\ are\ 11.2\ inches \times 8.4\ inches[/tex]

Hey there! I'm happy to help!

We want to multiply n-5 by -3. So, we multiply each term of n-5 by -3.

-3(n)=-3n

-3(-5)=15

So, our final expression is -3n+15.

Have a wonderful day! :D

Steps to solve:

-3(n - 5)

~Distribute

-3n + 15

Answer: Experimental Research

Step-by-step explanation: Experimental Research is the "classical" method of conducting an experiment to a scientific approach. It is the most rigorous of all research designs. In it, an independent variable is used to determine its influence on a dependable variable. Experimental research's unique quality is that it can link cause and effect through between variables.

This method works better at independent variables which can be manipulated or controled and can be conducted in laboratories or field settings.

There are 3 types of experimental research:

Experimental Research is important because it gives the opportunity to test

the hypothesis and developing a solid conclusion.

Answer: Pi,0.3,2/3,

Step-by-step explanation:

Answer: The first Option.

Step-by-step explanation:

y is greater than -1 and y is less than or equal to 4.

The range of the function will be Range = {y | 0 < x ≤ 6}. Then the correct option is C.

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The domain means all the possible values of x and the range means all the possible values of y.

The domain of the function is (-1, 4] and the range of the function will be

Range = {y | 0 < x ≤ 6}

Then the correct option is C.

So the planes given in the picture are,

Plane A or plane MSR

Plane PWM

Plane QTS

Plane WTS

Plane QPN

Plane PQT

Therefore, six faces of the given polygon will define the six planes.

Answer:

2/3,1,3/2,9/4,27/8

Step-by-step explanation:

f(1)=2/3

f(n)=f(n-1)×3/2

f(2)=f(2-1)×3/2=f(1)×3/2=2/3×3/2=1

f(3)=f(3-1)×3/2=f(2)×3/2=1×3/2=3/2

f(4)=f(4-1)×3/2=f(3)×3/2=3/2×3/2=9/4

f(5)=f(5-1)×3/2=f(4)×3/2=9/4×3/2=27/8

Supplementary angles are angles that add up to 180 degrees.

180 = 3x + 4 + 8x + 11

Combine like terms.

180 = 11x + 15

Subtract 15 from both sides.

165 = 11x

Divide both sides by 11

15 = x

m<ABC = 3x + 4 = 3(15) + 4 = 45 + 4 = 49 degrees.

Answer: x=2

Step-by-step explanation:

Let's solve your equation step-by-step.

3(x+2)=4(x+1)

Step 1: Simplify both sides of the equation.

3(x+2)=4(x+1)

(3)(x)+(3)(2)=(4)(x)+(4)(1)(Distribute)

3x+6=4x+4

Step 2: Subtract 4x from both sides.

3x+6−4x=4x+4−4x

−x+6=4

Step 3: Subtract 6 from both sides.

−x+6−6=4−6

−x=−2

Step 4: Divide both sides by -1.

−x −1 = −2 −1

Answer:

wym?but thanks

Step-by-step explanation:

Answer:

A. 0.0081

B. 0.1638

Step-by-step explanation:

From the question, we are told that 9% of the population are hopelessly romantic.

The percentage that are not hopelessly romantic = 100-9 = 91%

The probability of choosing a hopelessly romantic person = 9% = 9/100 = 0.09

The probability of choosing a person who is not hopelessly romantic = 91% = 91/100 = 0.91

Now, we want to select two people and calculate the following probability;

1. Both will be hopelessly romantic

Let’s have the people as A and B

The probability that both will be hopelessly romantic will the the product of being hopelessly romantic probability = 0.09 * 0.09 = 0.0081

b. Probability that at least one person is hopelessly romantic

What this means is that the probability that one of the two ONLY is hopelessly romantic;

We can have two cases here;

Probability (That A is hopelessly while B is not )or Probability (A is not and B is hopeless )

Thus we have :

(0.09 * 0.91) + (0.91 * 0.09) = 0.0819 * 2 = 0.1638

Answer:

55% or 0.55(as a decimal)

Step-by-step explanation:

40% of their clients buy auto insurance policies = P(A)

30% of their clients buy home insurance policies = P(H)

15% of their clients buy both home and auto insurance policies = P( A ∩ H)

The probability a randomly selected client buys a home or auto insurance policy = P (A ∪ H) is calculated as

P ( A ∪ H) = P(A ) + P ( H ) - P( A ∩ H)

= 40% + 30% - 15 %

= 70% - 15%

= 55%

Therefore, the probability that a randomly selected client buys a home or auto insurance policy is 55% or expressed as decimal = 0.55

Answer: 76.475

Step-by-step explanation:

Overall score = Σ (weight% × grade)

Hence,

(55% * 78.5) + (25% * 80) + ( 15% * 72) + (5% * 50)

43. 175 + 20 + 10.8 + 2.5
