Answer 1

Answer:

If it travels 12.56 ft in one revolution, then the circumference of the tire is 12.56 ft.

Circumference = 2 x π x radius

12.56=2 x 3.14 x radius

radius x 6.28=12.56

Radius= 2 ft

Step-by-step explanation:

Answer 2
The radios is 4 ft because 12 divided by 3 is 4

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.

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

Step-by-step explanation:

83+88+92+97=360

360/4=90

Can someone PLEASE show me how to do this! If f (x) = x^2 + 3x +2/ x +3, then f’ (x) =

Answers

Answer:

c

Step-by-step explanation:

The equation =( denominater * derivative of numerator - numerator * derivative of denominator) / denominator ^2

so the qstn is (x^2 + 3x +2) / (x+3)

apply the values as the above eqtn states

ie,[ (x+3) * derivative of (x^2 +3x + 2)] - [( x^2 +3x + 2) *derivative of (x+3)] /

(x+3)^2

derivative of numerator, (x^2 +3x + 2) is 2x+3

" of denominator, (x+3) is 1

so we get

[(x+3)* (2x + 3 ) - (x^2 +3x + 2) *1 ] / (x+3)^2

open the brackets

[ 2x^2 + 3x + 6x + 9 - x^2 +3x + 2 ] / (x+3)^2

subtract similar terms and we get the final answer in option c

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.

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.

An angle between 0 and 2π that is coterminal with 960° is

Answers

Answer:

4 pi/3

Step-by-step explanation:

960 degrees in standard position is the same thing as 960-360 = 600 degrees in standard position because rotating the second line 360 degrees just brings it back to where it started.

Do it again to get 600 - 360 = 240

240 degrees would end up in the same spot as 600 degrees and 960 degrees, so they are all coterminal.

Convert 240 degrees to radians:

240 * pi/180 = 4pi/3.

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)

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."
