<span>To regroup 378 x 6, you must first establish the place values of each digit. 3 has a place value of 300, because it is in the hundreds column; 7 has a place value of 70 because it is in the tens column; 8 has a place value of 8 because it is in the units column. This means you can regroup 378 x 6 as (300 x 6) + (70 x 6) + (8 x 6). This makes 2,268. </span>

mestny [16]

Answer:

60 hand shakes.

Step-by-step explanation:

We have been given that there are 6 married couples at a party.

This means there are 12 people in total.

We know that number of handshakes for n people is given by formula $\frac{n(n-1)}{2}$ .

We are also told that at the start of the party every person shakes hands once with every other person except his or her spouse.

So formula for this problem would be $\frac{n(n-1-1)}{2}$ or $\frac{n(n-2)}{2}$ .

Since total numbers of people is party is 12, so we will get:

$\frac{12(12-2)}{2}$

$6*10$

$60$

Therefore, there will be 60 hand shakes at the party.

In the figure we have three right angles .The triangles similar to each other .Similar triangles have sides in proportion .The altitude rule is true for the triangles .

The theorem states :The altitude to the hypotenuse of a right triangle is the mean proportional between the segments into which it divides the hypotenuse.

$\frac{part of hypotenuse}{altitude} =\frac{altitude}{other part hypotenuse }$

Substituting the values from the triangles we ahve:

$\frac{r}{h} =\frac{h}{s}$

s is the right answer
