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:
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.

HELP! WILL MARK BRAINLIEST!! Suppose for two real numbers x and y, both the sum x+y and product xy are integers. Either prove x and y must be rational numbers, or find a counterexample.
Answers
Step-by-step explanation:
A man by the name of Luigi Fonti wrote this. I hope it can guide you, as it did for me! "The set of rational numbers is closed for all the four operations, so x+y, x-y, x*y and x/y are rational too. And it is easy to demonstrate. A rational number can be expressed as a fraction of two integers. So, x can be expressed as a/b and y as c/d. Hence x+y = a/b + c/d = (ad+bc)/bd, which, as fraction of two integers, is rational."

Mr. Rahm purchases a new car for $24,000 and finances it with a 5-year simple interest loan at an annual rate of 3. 75%. What are Mr. Rahim's monthly car payments?
Answers
Answer:
$475
Step-by-step explanation:
The total amount Rahim will be paying is found from the simple interest formula ...
A = P(1 +rt) . . . . . P is the loan amount, r is the annual rate, t is the number of years.
A = $24,000(1 +0.0375×5) = $28,500
Spread over 60 monthly payments, that amounts to ...
$28,500/60 = $475 . . . per month
__
Additional comment
Mr. Rahim's loan has an APR of 6.98%. This sort of loan costs more than the interest rate might suggest, because interest is still being paid on principal that has already been repaid.

A rectangular parking lot is 120 feet long and 75 feet wide. Diego made another scale drawing of the parking lot at a scale of 1 to 180. The drawing he produced is also 8 inches by 5 inches. (Remember the video. Scales with no units represent the SAME UNIT. So how is Diego using a different scale than Lin, but ended up with the same drawing?) (12 inches = 1 foot) 2.) Explain or show how Diego's scale would produce an 8 inch by 5-inch drawing.
Answers
Answer:
We kindly invite you to read carefully the explanation detailed below for further details.
Step-by-step explanation:
At first we understand that Diego converted length and wide units from feet to inches ([tex]1\,ft = 12\,in[/tex]) and then he divided each term by 180, since he was using a reduction scale, so that rectangular parking lot can be represented on paper. That is:
Step 1 - Unit conversion:
[tex]l = 120\,ft[/tex] ([tex]l[/tex] - Length)
[tex]l = 120\,ft\times \frac{12\,in}{1\,ft}[/tex]
[tex]l = 1440\,in[/tex]
[tex]w = 75\,ft[/tex] ([tex]w[/tex] - Width)
[tex]w = 75\,ft\times \frac{12\,in}{1\,ft}[/tex]
[tex]w = 900\,in[/tex]
Step 2 - Applying scaling:
[tex]l' = \frac{l}{180}[/tex] ([tex]l'[/tex] - Scaled length)
[tex]l' = \frac{1440\,in}{180}[/tex]
[tex]l' = 8\,in[/tex]
[tex]w' = \frac{w}{180}[/tex] ([tex]w'[/tex] - Scaled width)
[tex]w' = \frac{900\,in}{180}[/tex]
[tex]w' = 5\,in[/tex]

Solve for x, I'm confused
Answers
[tex][Hello,BrainlyUser][/tex]
Answer:
x = 22
Step-by-step explanation:
Knowing that it a supplementary angle = 180 degree
It a right angle therefore it makes that 90 degree
Thus,
The 2 equation is
4x + 2 = 90
3x + 24 = 90
Let first solve this one
4x + 2 = 90
Subtract 2 from both sides
4x + 2 - 2= 90-2
Simplify
4x = 88
Divide both sides by the same factor
4x/4 = 88/4
Simplify
x = 22
Now the second equation:
3x + 24 = 90
Subtract 24 from both sides
3x + 24 - 24 = 90 -24
Simplify
3x = 66
Divide both sides by the same factor
3x/3 = 66/3
Simplify
x = 22
Hence, x = 22.

So, length = 2w
Perimeter of rectangle = 2*length + 2*width
2*length + 2*width = 90
2*2w + 2*w= 90
4w + 2w = 90
6w = 90
Divide both sides by 6
w = 90/6
w = 15 ft

A figure skater needs a total score of at least 90 to move on to the next round. The total score is the average of four judges’ scores. The first three judges’ scores were 83, 88, and 92. The figure skater made it to the next round.
What is the minimum score the fourth judge could have given?
Answers
Answer:
the skater needs to get a score of 97 [or more ]
Step-by-step explanation:
[ 83 + 88 + 92 + M ] / 4 ≥ 90 multiply both sides by 4
83 + 88 + 92 + M ≥ 360 simplify
263 + M ≥ 360 subtract 263 from both sides
M ≥ 97 → the skater needs to get a score of 97 [or more ]
Answer:97

True or False? When Liesl used the quadratic formula to solve a quadratic equation, she noticed the value of the discriminant was a perfect square. She immediately determined that she could have factored the quadratic equation she was solving.
Answers
Liesl is correct, if the discriminant is a perfect square, then we can factorize the quadratic equation.
Is the statement true or false?For a quadratic equation:
y = a*x^2 + b*x + c
The discriminant is:
D = b^2 - 4ab
Notice that for the equation:
0 = a*x^2 + b*x + c
The solutions are given by:
[tex]x = \frac{-b \pm \sqrt{D}}{2a}[/tex]
If D is a perfect square, then we know that the square root has solutions, so there are two values:
[tex]x_1 = \frac{-b + \sqrt{D}}{2a}\\\\x_2 = \frac{-b - \sqrt{D}}{2a}[/tex]
Now with these solutions, we can factorize our equation as:
[tex]y = a*(x - ( \frac{-b + \sqrt{D}}{2a}))*(x - ( \frac{-b - \sqrt{D}}{2a}))[/tex]
So Liesl is correct, if the discriminant is a perfect square, we can factorize the quadratic equation.

You have a bull's eye where each section is 2" wide as shown in the diagram. Find the following probabilities.
Answers
Answer:
a) 1/16
b) 7/16
Step-by-step explanation:
a) The area of the outside circle is π (8")² = 64π in².
The area of the center circle is π (2")² = 4π in².
So the probability is (4π / 64π) = 1/16.
b) The area of the outside strip is π [(8")² − (6")²] = 28π in².
So the probability is (28π / 64π) = 7/16.

Explain or show that the point (5, -4) is a solution to this system of equations:
3x - 2y = 23
2x + y = 6
Answers
Answer:
see explanation
Step-by-step explanation:
If (5, - 4) is a solution to the system then both equations will be true when (5, - 4) is substituted into them.
Substitute (5, - 4) into the left side of the equations and if equal to the right side then (5, - 4) is a solution.
3(5) - 2(- 4) = 15 + 8 = 23 = right side
2(5) + (- 4) = 10 - 4 = 6 = right side
Then (5, - 4) is a solution to the system of equations.
or by solving
3x - 2y = 23 → (1)
2x + y = 6 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the y- term
4x + 2y = 12 → (3)
Add (1) and (3) term by term to eliminate y, that is
7x = 35 ( divide both sides by 7 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (2)
2(5) + y = 6
10 + y = 6 ( subtract 10 from both sides )
y = - 4
Solution is (5, - 4 )
Using the concept of simultaneous equation, the solution to the system of equations is (5, - 4)
Given the system of linear equations :
3x - 2y = 23 _______(1)2x + y = 6 ________ (2)From (2) :
y = 6 - 2x ______(3)Substitute (3) into (1)
3x - 2(6 - 2x) = 23
3x - 12 + 4x = 23
7x = 23 + 12
7x = 35
Divide both sides by 7 to isolate x
x = 35 / 7
x = 5
From (3)
y = 6 - 2(5)
y = 6 - 10
y = -4
Therefore, the solution to the system of equation is (5, - 4)
