Answer:

Step-by-step explanation:

We know the area of a triangle is B*H/2. For Triangle ABC, the area is 75. So the equation formed is:

15*h/2 = 75

15*h = 150

h = 10.

Now we know the height for the bigger triangle is 10. Since the scale factor from 15 --> 3 is 5, the height for triangle EFG is 2 because 10 divided by 5 is 2. Since we now know the height of the triangle is 2 and the base is 3, we can form the equation:

3*2/2 = Area

6/2 = Area

3 = Area

We know the area is 3. The key thing was we didn't divide triangle ABC with 5 because the area would not be the same. We must use the equation and from this we will get the correct area.

Answer:

Step-by-step explanation:

It is 15.

(15×x) /2 =75

×2. ×2

X×15=150

/15. /15

X=10

(3×x) /2 =area of triangle

(3×10) /2

30/2

15= area of triangle

The entire exterior of a large wooden cube is painted red, and then the cube is sliced into n^3 smaller cubes (where n > 2).
svlad2 [7]

Answer:

B. 6n^2-12 n +8

Step-by-step explanation:

Given,

The number of smaller cubes = n^3

So, the number of cubes that have no coloured faces.  = (n-2)^3,

Note : If a cube painted outside having side n is split into n³ cubes, then the volume volume that is not painted = (n-2)³

Thus, the remaining cubes that have been painted red on at least one of their faces

= Total cubes - cubes with no painted face

= n^3 -(n-2)^3

=n^3 - (n^3 - 8 - 6n^2 +12n)

=6n^2-12 n +8

Hence, OPTION B is correct.

In this set, most of the values are within the 25-35 range, more or less. But out of all of those numbers, one of the is too small to make sense, which is 7.
