Answer: 8 textbooks

Step-by-step explanation:

Sold 40 notebooks = 40 x $4 = $160

$800 - $160 = $640 left to sell

$640/$80 (cost of textbook) = 8 textbooks need to be sold

Answer:

-1

Step-by-step explanation:

slope is the change in y over change in x

from one point to another you have to go down 5 and to the right 5

since we’re moving down 5 is negative

so the slope is -5/5 which simplified to -1

Answer:

BE = 49

Step-by-step explanation:

In triangle BDC

  65^2=56^2+BD^2

  65^2-56^2=BD^2

  4225-3136=BD^2

  1089=BD^2

   33=BD

In triangle FDE

    65^2=63^2+DE^2

    4225-3969=DE^2

    256 = DE^2

    16=DE

since ED+DB=BE

THEREFORE

      16+33=BE

         49=BE

Answer:

Yes, you can determine the number of people who do not run or lift weights by first finding that 55 people do not lift weights, and that 35 people run, but do not lift weights. Subtracting 35 from 55, you get that 20 people do not do either.

Step-by-step explanation:

The required value of a number of people is 20 who don't do either.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

Column 1 has the entries run, do not run, and total. Column 2 is called lift weights, and it has the values 40, blank, and 65. Column 3 is captioned "do not lift weights" and has entries blank, x, and blank. Column 4 is called total and has the entries 75, blank, and 120.

As per the given information, the required solution would be as:

The number of people who do not run or lift weights by first determining that 55 individuals do not lift weights and 35 people run but do not lift weights. When you subtract 35 from 55, you get 20 people who don't do either.

Thus, the required value of a number of people is 20 who don't do either.

Step-by-step explanation:

Answer:

The top left, (7 + 9x = 9x + 7) is infinite, and the top right, (12 - 15x = -2 - 15x) has no solution

7 + 9x = 9x + 7

10x - 4 = -4 + 10x

-2x + 5 = -2x + 5

12 - 15x = -2 - 15x

6x + 5 = 8 + 6x

5/4x - 1 = 1 + 5/4x |

3x + 4 = 8x - 9

9 + 1/2x = 5x - 1

-4x - 5 = 6 - 11x

Answer:

john is 20 years old

Step-by-step explanation:

we can take the ages as

john= x

jean= x+12

according to question

x+(x+12)= 52

2x+12= 52

transpose

2x= 52-12

2x= 40

x= 40/2

x= 20

john= 20

jean= 20+12= 32

therefore john is 20 years old and jean is 32 years old

Answer:

120.

Step-by-step explanation:

Para poder determinar el numero de canicas que Juan tiene, se debe obtener el múltiplo común mayor entre 2, 3 y 5, que sea menor a 200. Así, para ser múltiplo de 2 debe ser un número par, para ser múltiplo de 3 sus dígitos deben sumar un número divisible por 3, y para ser múltiplo de 5 debe terminar en 5 o 0.

Así, dado que 0 es par, se debe tratar de un número terminado en 0, divisible por 3: puede tratarse de los números 120, 150 o 180. Así, dado que 119/7 es igual a 17, sobrando 1 para completar el número 120, el número de canicas que Juan tiene es 120.

Answer:

I know its not a or b but c and d are the same answer.

Step-by-step explanation:

From the given expressions, option (D) gives value 7. Option (D) is correct.

An algebraic expression is consists of variables, numbers with various mathematical operations,

Given that,

The value of p is 64 and the value of q is 12.

To determine the expression which gives value 7.

Solve with the help of options,

(A)

3√p - q + 5

Substitute the value of p and q here,

= 3√64 - 12 + 5

= 3×8 -12 +5

= 24 - 7

= 17

(B)

3(√p - q) + 5

Substitute the value of p and q here,

= 3(√64 - 12) + 5

= 3(-4)+ 5

= -12 + 5

= -7

(C)

3(√p) - q + 5

Substitute the value of p and q here,

= 3(√64) - 12 + 5

= 3×8 -12 +5

= 24 - 7

= 17

(D)

3√p - (q + 5)

Substitute the value of p and q here,

= 3√64 - (12 + 5)

= 24 - 17

= 7

Hence, option (d) gives value 7.

Answer:

Reflection over the Y axis

Step-by-step explanation:

I got it right on imagine math.

The transformation rule is given as the reflection over y-axis.The correct option is (C).

The graph of a function can be transformed by either shifting it in the right, left, up or down.

When the transformation is rightwards, the function becomes as f(x - a).

For left shifting it is f(x + a).

Take any coordinate to describe the transformation.

For point E and E' the coordinates are given as (-5, 3) and (5, 3).

Since, y coordinate is the same while the sign of x coordinate has changed.

Point E' is the reflection of E across y-axis.

Hence, the required transformation for the given graph is reflection over y-axis.

Complete Question

Evaluate the Fermi function for an energy kT above the Fermi energy. Find the temperature at which there is a 1% probability that a state, with an energy 0.5 eV above the Fermi energy, will be occupied by an electron.

Answer:

a

The Fermi function for the energy KT is  [tex]F(E_o) = 0.2689[/tex]

b

The temperature is  [tex]T_k = 1261 \ K[/tex]

Step-by-step explanation:

From the question we are told that

   The energy considered is  [tex]E = 0.5 eV[/tex]

Generally the Fermi  function is mathematically represented as

       [tex]F(E_o) = \frac{1}{e^{\frac{[E_o - E_F]}{KT} } + 1 }[/tex]

    Here K is the Boltzmann constant with value [tex]k = 1.380649 *10^{-23} J/K[/tex]

            [tex]E_F[/tex]  is the Fermi energy

            [tex]E_o[/tex]  is the initial energy level which is mathematically represented as

     [tex]E_o = E_F + KT[/tex]

So

     [tex]F(E_o) = \frac{1}{e^{\frac{[[E_F + KT] - E_F]}{KT} } + 1}[/tex]

=>   [tex]F(E_o) = \frac{1}{e^{\frac{KT}{KT} } + 1}[/tex]

=>   [tex]F(E_o) = \frac{1}{e^{ 1 } + 1}[/tex]

=>   [tex]F(E_o) = 0.2689[/tex]

Generally the probability that a state, with an energy 0.5 eV above the Fermi energy, will be occupied by an electron is mathematically represented by the  Fermi  function as

     [tex]F(E_k) = \frac{1}{e^{\frac{[E_k - E_F]}{KT_k} } + 1 } = 0.01[/tex]

Here[tex]E_k[/tex] is that energy level that is  0.5 ev above the Fermi energy  [tex]E_k = 0.5 eV + E_F[/tex]

=>   [tex]F(E_k) = \frac{1}{e^{\frac{[[0.50 eV + E_F] - E_F]}{KT_k} } + 1 } = 0.01[/tex]

=>   [tex]\frac{1}{e^{\frac{0.50 eV ]}{KT_k} } + 1 } = 0.01[/tex]

=>   [tex]1 = 0.01 * e^{\frac{0.50 eV ]}{KT_k} } + 0.01[/tex]

=>   [tex]0.99 = 0.01 * e^{\frac{0.50 eV ]}{KT_k} }[/tex]

=>   [tex]e^{\frac{0.50 eV ]}{KT_k} } = 99[/tex]

Taking natural  log of both sides

=>   [tex]\frac{0.50 eV }{KT_k} } =4.5951[/tex]

=>    [tex]0.50 eV =4.5951 * K * T_k[/tex]

Note eV is electron volt and the equivalence in Joule is     [tex]eV = 1.60 *10^{-19} \ J[/tex]

So

     [tex]0.50 * 1.60 *10^{-19 } =4.5951 * 1.380649 *10^{-23} * T_k[/tex]

=>   [tex]T_k = 1261 \ K[/tex]
