Answer: Total Length of ribbon is 99 cm

Step-by-step explanation:

Here ribbon was cut into three parts in the ratio 1:3:5

let x be the common multiple of the above ratio

therefore, the lengths of the three parts of the ribbon is 1x,3x,5x

now, given is that the shortest part i.e 1x is equals to 11cm

i.e   1x=11

        x=[tex]\frac{11}{1}[/tex]=11cm

     now lengths of the ribbon will be

      1x=11cm, 3x=3*11=33cm, 5x=5*11=55cm

 now total length of piece of ribbon = 1x+3x+5x=9x=9*11=99cm

Answer:

  n < -15/4

Step-by-step explanation:

You want to use the discriminant to find the values of n for which the quadratic 3z² -9z = (n -3) has only complex solutions.

The discriminant of quadratic equation ax²+bx+c = 0 is ...

  d = b² -4ac

The given quadratic can be put in this form by subtracting (n-3):

  3z² -9z -(n -3) = 0

This gives us ...

and the discriminant is ...

  d = (-9)² -4(3)(-(n-3)) = 81 +12(n -3)

  d = 12n +45

The equation will have only complex solutions when the discriminant is negative:

  d < 0

  12n +45 < 0 . . . . . use the value of the discriminant

  n +45/12 < 0 . . . . . divide by 12

  n < -15/4 . . . . . . . subtract 15/4

There will be two complex solutions when n < -15/4.

The solution for the given system of equations is x[1] = -1 and x[2] = 2.

A system of linear equations (or linear system) is a collection of one or more linear equations involving the same variables.

Given are the following equations as -

5 x[1] + 5 x[2] = 5

2 x[1] + 3 x[2] = 4

Assume that -

x[1] = a    

x[2] = b

Then, we can write the equations as -

5a + 5b = 5

2a + 3b = 4

Now -

5a + 5b = 5

5(a + b) = 5

a + b = 1

a = 1 - b

So, we can write -

2a + 3b = 4

as

2(1 - b) + 3b =4

2 - 2b + 3b = 4

b = 4 - 2

b = 2 = x[2]

Then

a = 1 - 2

a = -1 = x[1]

Therefore, the solution for the given system of equations is x[1] = -1 and x[2] = 2.

Given:

new game cost - $ 64

used game cost - $ 43

Luis spent $ 343

Required:

Number of used games Luis purchased

Solution

Let: x be the number of new games Luis bought

x + 3 be the number of used games Luis bought

Total cost = $ 343

Total Cost = (No. of new games bought)(Cost of new games) + (No. of used games bought)(Cost of used games)

$ 343 = ( x ) ( $ 64 ) + ( x + 3 ) ( $ 43 )

343 = 64x + 43 ( x + 3 )

343 = 64x + 43x + 129

343 - 129 = 107x

214 = 107x

2 = x

x = 2

x be the number of new games Luis bought 2

x + 3 be the number of used games Luis bought 2 + 3 = 5

Answer:

Luis purchased 5 used games

To check:

Substitute x into the equation,

343 = x ( 64 ) + (x + 3 ) (43)

343 = 2 ( 64 ) + (2 + 3)(43)

343 = 2 (64) + (5) (43)

343 = 128 + 215

343 = 343

Using the normal distribution and the central limit theorem, it is found that:

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given by the following rule:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation of the glucose levels are given, respectively, by:

[tex]\mu = 85, \sigma = 25[/tex]

The probability of a reading of less than 40 mg/dl(severe excess insulin) is the p-value of Z when X = 40, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (40 - 85)/25

Z = -1.8.

Z = -1.8 has a p-value of 0.0359.

For the mean of two tests, the standard error is:

s = 25/sqrt(2) = 17.68.

Hence, by the Central Limit Theorem:

[tex]Z = \frac{X - \mu}{s}[/tex]

Z = (40 - 85)/17.68

Z = -2.55.

Z = -2.55 has a p-value of 0.0054.

For 3 tests, we have that:

s = 25/sqrt(3) = 14.43.

Z = (40 - 85)/14.43

Z = -3.12.

Z = -3.12 has a p-value of 0.0009.

For 5 tests, we have that:

s = 25/sqrt(5) = 11.18.

Z = (40 - 85)/11.18

Z = -4.03

Z = -4.03 has a p-value of 0.

Answer:

(b) f(2) = 28

(c) f(-2) = -20

Step-by-step explanation:

f(2) = -2^3 + 7 x 2^2 - 2 x 2 + 12           f(-2) = -2^3 + 7 x -2^2 - 2 x -2 + 12

1. Calculate Exponents

-2^3 = -8                                               -2^3 = -8

2^2 = 4                                                  -2^2 = -4

-8 + 7 x 4 - 2 x 2 + 12                           -8 + 7 x -4 - 2 x -2 + 12

2.  Multiply (left to right)

7 x 4 = 28                                               7 x -4 = -28

2 x 2 = 4                                                 2 x -2 = -4

-8 + 28 - 4 + 12                                    -8 - 28 - (-4) + 12

3. Add (left to right)

-8 + 28 = 20                                           -8 + -28 = -36

20 - 4 = 16                                              -36 - (-4)= -32

16 + 12 = 28                                            -32 + 12 = -20

In order to represent three consecutive odd numbers, we can use the expressions "x", "x+2" and "x+4".

If we add the square of each number, the result is 83, so we can write the following inequality:

Let's solve this quadratic equation using the quadratic formula, with a = 1, b = 4 and c = -21:

If we assume the numbers are positive, the numbers are 3, 5 and 7.

EXPLANATION

This is a right triangle, so we have to apply the Pythagorean Theorem to find the value of a.

We know the length of the hypotenuse which is 5, and the length of one of the legs, which is 2. The Pythagorean Theorem for this problem is,

Subtract 2² from both sides,

And take the square root to both sides,

Hence, the value of a is √21.

The time on which parents evening was due to finish was 19 hour 20 minutes.

Time is the ongoing pattern of existence and things that happen in what seems to be an irreversible order from the past, through the present, and into the future.

It is a component quantity of various measurements used to order events, compare the length of events or the time gaps between them, and quantify rates of change of quantities in objective reality or in conscious experience. Along with the three spatial dimensions, time is frequently considered a fourth dimension.

The International System of Units is built upon the seven base units of measurement stipulated by the Système International d'Unités (SI), from which all other SI units are derived. The primary unit of time is the second. The second can be shortened using either the letter S or the letter sec.

20 consecutive appointments of 10 mins = 20 × 10 mins

                                                                     = 200 min

                                                                      = 3 hours 20 mins

A break of 15 mins = 3 hours 20 mins + 15 min

                               = 3 hours 35 mins

The time that the parents evening due to finish = 15h 45 min +3h 35 mins

                                                                               = 19h 20min

Thus, the time on which parents evening was due to finish was 19h 20min.

The rate at which the distance between the two cars increased four hours later is 30 mi/h.

First of all, we would determine the distances travelled by each of the cars. The distance travelled by the first car after four (4) hours is given by:

Distance, x = speed/time

Distance, x = 24/4

Distance, x = 6 miles.

For the second car, we have:

Distance, y = speed/time

Distance, y = 18/4

Distance, y = 4.5 miles.

After four (4) hours, the total distance travelled by the two (2) cars is given by this mathematical expression (Pythagorean theorem):

z² = x² + y²

Substituting the parameters into the mathematical expression, we have;

z² = 6² + 4.5²

z² = 36 + 20.25

z² = 56.25

z = 7.5 miles.

Next, we would differentiate both sides of the mathematical expression (Pythagorean theorem) with respect to time, we have:

2z(dz/dt) = 2x(dx/dt) + 2y(dy/dt)

Therefore, the rate of change of speed (dz/dt) between the two (2) cars is given by:

dz/dt = [x(dx/dt) + y(dy/dt)]/z

dz/dt = [6(24) + 4.5(18)]/7.5

dz/dt = [144 + 81]/7.5

Step-by-step explanation:

First find out how far the cars are apart after 4 hours

24 * 4 = 96 mi = y

18 * 4 = 72 mi = x

Now use the pythagorean theorem

   s^2 =  ( x^2 + y^2 )                shows s = 120 miles apart at 4 hours

Now s^2 = x^2 + y^2     Differentiate with respect to time ( d  / dt )

       2 s ds/dt    =  2x dx/ dt  + 2y dy / dt

             ds/dt    =   (x dx/dt + y dy/dt)/s

                           =  (72(18)  + 96(24)) / 120

               ds/dt   = 30 mi/hr
