                                   Teachers / Students  =  3 / 74

                                      Teachers  /  2,500  =  3 / 74

To solve a proportion,
you cross-multiply:            Teachers x 74  =  2,500 x 3

Divide each side by  74 :     Teachers  =  2,500 x 3 / 74

                                                                  =  101.4     ===>  101 teachers

Yanka [14]

Answer:

Step-by-step explanation:

14 = 1000 e^{ k*1}

.014 = e^{k*1}

ln(.014) = k ln(e)

k = -4.268

~~~~~~~~~~~~~~~~~~

after 3 hrs

1000 e^{ -4.268*3}

0.00274

~~~~~~~~~~~~~~~

4 = 1000 e^{ -4.268*t}

.004 =  e^{ -4.268*t}

ln(.004)/-4.268 = t

t = 1.29368 hrs

Surface area of a 4m and 4m and 4m cube
jeka94

Answer: 96 m²

Step-by-step explanation: Surface area is the sum of the areas of all of the faces of a 3-dimensional figure.

So to find the surface area of a cube, it's important to understand that each face of a cube has the same area so we can simply find the area of one face of a cube and multiply by the number of faces which is 6.

To find the area of one face of a cube, we can use the formula for the area of a square which is S².

Since the length of a side is 4 meters, we have (4 m)² or 4 meters x 4 meters which is 16 m².

Now, since there are six sides to a cube, we have 6 (16 m)² which is equal to 96 m². So the surface area of the cube is 96 m².
