WILL GIVE BRAINLIEST! <br>What is the answer for question (iv)? <br>please help!

Leviafan [203]

Step-by-step explanation:

$\triangle ABC \sim \triangle ADE... (given) \\\\\therefore \frac {AC}{AE} = \frac {BC}{DE}.. (csst) \\\\\therefore \frac {5}{5+2x} = \frac {x+3}{4x+1}\\ \\ \therefore \: 5(4x + 1) = (5 + 2x)(x + 3) \\ \therefore \:20x + 5 = 5x + 15 + 2 {x}^{2} + 6x \\ \therefore \:20x + 5 =2 {x}^{2} + 11x + 15 \\ \therefore \:2 {x}^{2} + 11x + 15 -2 0x - 5 = 0\\ \therefore \:2 {x}^{2} - 9x + 10 = 0\\ \therefore \:2 {x}^{2} - 5x - 4x+ 10 = 0\\ \therefore \:x(2x - 5) - 2(2x - 5) = 0 \\ \therefore \:(2x - 5)(x - 2) = 0 \\ 2x - 5 = 0 \: \: or \: \: x - 2 = 0 \\ x = \frac{5}{2} \: \: or \: \: x = 2 \\ x = 2.5 \: \: or \: x = 2 \\ x = 2.5 \: is \: largest \\ \\ \frac{A(\triangle ABC)}{ A(\triangle ADE)} = \frac{AC ^{2} } {AE^{2} } \\ \\ \frac{A(\triangle ABC)}{ A(\triangle ADE)} = \frac{5 ^{2} } {(5 + 2x)^{2} } \\ = \frac{25}{(5 + 2 \times 2.5)^{2} } \\ = \frac{25}{ {10}^{2} } \\ = \frac{25}{100} \\ \\ \frac{A(\triangle ABC)}{ A(\triangle ADE)} = \frac{1}{4} \\$

Can someone help me ? If Tina can type a paper in 5 hours and together she and Tyra can type the paper in 2 hours, how long woul

SpyIntel [72]

Answer: 3 1/3 hours

Step-by-step explanation:

Tina rate: 1/5 job/hr

Together rate: 1/2 job/hr

Tyra rate: 1/x job/hr

---------

Equation:

rate + rate = together rate

1/5 + 1/x = 1/2

2x + 10 = 5x

3x = 10

x = 3 1/3 hrs (time for Tyra to do the job alone)

The owner of a local golf course wanted to determine the average age (in years) of the golfers that played on the course. In a r

Katyanochek1 [597]

Answer:

e. We are 90% confident that the average age of all golfers that play on the golf course is between 38.6 and 44.6 years old.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

In this question:

90% confidence interval for the average age of golfers in the course is of (38.6, 44.6). This means that we are 90% sure that the true average age of all golfers in the course is between these two values, that is, the correct answer is given by option e.

Diego says the constant of proportionality is 550 Andrew say is the constant of proportionality is 9 1/6 do you agree with eithe

icang [17]

Answer:

The question is incomplete. The complete question is :

A plane traveling at a constant speed flew over Pittsburgh, Saint Louis, Albuquerque, and Phoenix on its way from New York to San Diego.

Complete the table as you answer the questions. Be prepared to explain your reasoning.

segment time distance speed

Pittsburgh to Saint Louis 1 hour 550 miles

Saint Louis to Albuquerque 1 hour 42 minutes

Albuquerque to Phoenix 330 miles

Step-by-step explanation:

We can complete the table as :

segment time distance speed

Pittsburgh to Saint Louis 1 hour 550 miles 550 miles/hour

Saint Louis to Albuquerque 1 hour 42 minutes 93.5 miles 550 miles/hour

Albuquerque to Phoenix 3/5 hour 330 miles 550 miles/hour

Since it is given in the question that the plane is flying in a constant speed from one place top another place.

So, it is maintaining the same speed to cover different distances for different time.

Thus the constant of proportionality is 550.
