Chris made hamburgers for his family and they each had a diameter of 3 in. If he made 16 hamburgers.
Alenkasestr [34]

Answer:

The total area for all 16 hamburgers is <u>113.04 in²</u>.

Step-by-step explanation:

Given:

Chris made hamburgers for his family and they each had a diameter of 3 in.

If he made 16 hamburgers.

Now, to find the total area for all 16 hamburgers.

So, the diameter 3 in is given and we need first to find the radius:

Radius\ (r)=\frac{Diameter}{2} =\frac{3}{2} =1.5\ in.

Now, to get the area of a hamburger we put formula:

<u><em>(Taking the value of π = 3.14.)</em></u>

Area=\pi r^2\\\\Area=3.14\times (1.5)^2\\\\Area=3.14\times 2.25\\\\Area=7.065\ in^2.

Now. to get the total area of 16 hamburgers by multiplying 16 by the area of a hamburger:

7.065\times 16\\\\=113.04\ in^2.

Therefore, the total area for all 16 hamburgers is 113.04 in².

Assoli18 [71]

Answer:

  • 8

Explanation:

1)<u> Principal quantum number, n = 2</u>

  • n is the principal quantum number and indicates the main energy level.

<u>2) Second quantum number, ℓ</u>

  • The second quantum number, ℓ,  is named, Azimuthal quantum number.

The possible values of ℓ are from 0 to n - 1.

Hence, since n = 2, there are two possible values for ℓ: 0, and 1.

This gives you two shapes for the orbitals: 0 corresponds to "s" orbitals, and 1 corresponds to "p" orbitals.

<u>3) Third quantum number, mℓ</u>

  •    The third quantum number, mℓ, is named magnetic quantum number.

The possible values for mℓ are from - ℓ to + ℓ.

Hence, the poosible values for mℓ when n = 2 are:

  • for ℓ = 0: mℓ = 0
  • for ℓ = 1, mℓ = -1, 0, or +1.

<u>4) Fourth quantum number, ms.</u>

  • This is the spin number and it can be either +1/2  or -1/2.

Therfore the full set of possible states (different quantum number for a given atom) for n = 2 is:

  • (2, 0, 0 +1/2)
  • (2, 0, 0, -1/2)
  • (2, 1, - 1, + 1/2)
  • (2, 1, -1, -1/2)
  • (2, 1, 0, +1/2)
  • (2, 1, 0, -1/2)
  • (2, 1, 1, +1/2)
  • (2, 1, 1, -1/2)

That is a total of <u>8 different possible states</u>, which is the answer for the question.

Help!!!! Please just number 11 worth 90 points!!!!!
timurjin [86]

Answer:

6.75 hrs are missing

Step-by-step explanation:

First, change all fractions into decimals:

8 = 8

7 1/4 = 7 + 0.25 = 7.25

8 1/2 = 8 + 0.50 = 8.50

Next, add all numbers gotten together:

8 + 7.25 + 8.50 = 23.75

Subtract the number gotten from the total

30.5 - 23.75 = 6.75

Arisa [49]

Answer:

Jessica Bradley - 856 Points

Tina​ Harner - 707 Points

Step-by-step explanation:

FULL QUESTION:

The highest scorer of the​ women's basketball championship was Jessica Bradley. She scored 149 more points than Tina​ Harner, her teammate.​ Together, Bradley and Harner scored 1563 points. How many points did each player score during the​ championship?

Let T = points scored by Tina Harner

     J = points scored by Tina Harner

She scored 149 more points than Tina​ Harner, her teammate.​ This means;

J = T + 149...........(i)

Together, Bradley and Harner scored 1563 points. This means;

J + T = 1563 .........(ii)

How many points did each player score during the​ championship?

We have to find T and J.

Substitute value of J from eqn (i) into eqn (ii)

T + 149 + T = 1563

2T = 1563 - 149 = 1414

T = 1414 / 2 = 707

J = 707 + 149 = 856

Jessica Bradley - 856 Points

Tina​ Harner - 707 Points
