He spilled 1 and 5/8 cups because 2-3/8= 1 5/8. To check that, use 1 5/8+ 3/8= 2 cups.

Nicholas says that (2^6)(2^6) equals 2^12, which also equals 4^6. is this true? PLEASE EXPLAIN

Umnica [9.8K]

When you multiply two numbers in exponential notation whose bases are the same, you just keep the base the same and add the exponents.

In this case, you have (2^6) * (2^6) = 2^(6 + 6) = 2^12.

We can change the base of 4^6 into 2:

(2^2)^6

Is this the same as 2^12? Well, when we have an expression like that above, we multiply the exponents together, so we get: (2^2)^6 = 2^12.

Therefore, Nicholas is correct.

6 points are place on the line a, 4 points are placed on the line b. How many triangles is it possible to form such that their v

yawa3891 [41]

Answer: 96

Step-by-step explanation:

Ok, lines a and b are parallel.

We can separate this problem in two cases:

Case 1: 2 vertex in line a, and one vertex in line b.

Here we use the relation:

"In a group of N elements, the total combinations of sets of K elements is given by"

$C = \frac{N!}{(N - K)!*K!}$

Here, the total number of points in the line is N, and K is the ones that we select to make the vertices of the triangle.

Then if we have two vertices in line a, we have:

N = 6, K = 2

$C = \frac{6!}{4!*2!} = \frac{6*5}{2} = 3*5 = 15$

And the other vertex can be on any of the four points on the line b, so the total number of triangles is:

C = 15*4 = 60.

But we still have the case 2, where we have 2 vertices on line b, and one on line a.

First, the combination for the two vertices in line b is:

We use N = 4 and K = 2.

$C = \frac{4!}{2!*2!} = \frac{4*3}{2} = 6$

And the other vertice of the triangle can be on any of the 6 points in line a, so the total number of triangles that we can make in this case is:

C = 6*6 = 36

Then, putting together the two cases, we have a total of:

60 + 36 = 96 different triangles
