Ohama is landing a plane on the runway. He's trying to decide where he should deploy the plane's landing gear so that the plane comes to a stop exactly at the end of the runway. The runway is 600 yards long, and the plane will travel half the distance with the landing gear than without the landing gear. Where should he deploy the landing gear ?

Answers

Answer 1

Answer:

Answer:

Let's define:

A = distance traveled before deploying the landing gear

B = distance traveled after deploying the landing gear.

We must have that the sum of those two distances must be equal to 600 yards.

A + B = 600 yd.

And we know that:

" the plane will travel half the distance with the landing gear than without the landing gear."

Then we have that:

B = A/2.

Now we can replace this last equation in the first one:

A + B = 600yd

A + A/2 = 600yd.

(3/2)*A = 600yd.

A = (2/3)*600yd = 400yd.

Ohama should deploy the landing gear 400 yd into the runway.

Consider julie's scores on three final exams (x), along with the class means and standard deviations: subject x mean standard deviation history 75 70 5 english 92 90 10 math 80 70 3 science 84 70 7 compared to the other students who took the test, in what class is was julie's highest score?

Answers

Answer: In order to find in what class Julie's has scored highest, we need to find the z score corresponding to Julie's score. The subject who has the highest z score will indicate that Julie has scored highest in that subject.

Z score for History:

$z=(75-70)/(5) =1$

z score for english:

$z=(92-90)/(10) =0.2$

z score for math:

$z=(80-70)/(3) =3.33$

z score for science:

$z=(84-70)/(7) =2$

Since the z score for Math is highest, therefore, in Math class Julie's score is highest.

Mike has some money in his account. Every month, he uses the same amount of money from his account to pay for his aerobics classes. The table below shows the amount of money left in his account after a certain amount of time, in months:What is the value of the rate of change of the function for this table and what does it represent in this situation?
$50 per month; the initial amount of money in the account
−$50 per month; the amount of money withdrawn per month
−$280 per month; the amount of money withdrawn per month
$280 per month; the initial amount of money in the account

Answers

The correct answer is -$50 per month; the amount of money withdrawn per month. From one month to the next, Mike loses 50 dollars from his bank account, presumably because he's withdrawing it. To find this, just subtract each number from the number below it.

230 - 280 = -50
180 - 230 = -50
130 - 180 = -50

Therefore, the rate of change is -50, because Mike loses $50 each month. This means that he withdraws $50 from his bank account each month.

Hope this helps!

Hich expression is rational? a. 4.121221222… b.square root of 36 c. square root of 21 d.1.192744502…

Answers

Answer: The correct option is (B) square root of 36.

Step-by-step explanation: We are given to select the correct number that is irrational.

RATIONAL NUMBER: The digits after the decimal are either terminating or repeating.

IRRATIONAL NUMBER: The digits after the decimal are non-repeating and non-terminating.

Option (A) is 4.121221222 . . .

Here, the digits after the decimal are non-repeating and non-terminating. So, the given number is irrational.

Option (B) is square root of 36, which is equal to 6.

6 = 6.00.

Here, the digits after the decimal are terminating. So, the given number is rational.

Option (C) is square root of 21.

We know √21 = 4.5825756 . . .

Here, the digits after the decimal are non-repeating and non-terminating. So, the given number is irrational.

Option (D) is 1.192744502 . . .

Here, the digits after the decimal are non-repeating and non-terminating. So, the given number is irrational.

Thus, the rational number is square root of 36.

Option (b) is correct.

A rational number is any number that can be expressed as the quotient of fraction of two integers.So the answer is b.square root of 36 = √36=6 because 6 is the quotient of 6/1
