Answer:

write the percent divided by 100

Step-by-step explanation:

1) write the percent divided by 100.

2) if the percent is not a whole number, multiply both top and bottom by 10 for every number after the decimal point.

3) reduce (simplify) the fraction.

A, B, and C are collinear, and B is between A and C. The ratio of AB to AC is 1:2 If A is at (6,3) and B is at (-1,2), what are

Maksim231197 [3]

Answer:

The coordinates of C is (-8,1)

Step-by-step explanation:

Looking at the attached image, you'd see that, AB is 1 and BC is 1, that's because we are told that ratio of AB to AC is 1:2 meaning, AC is 2 and AB is 1. Therefore for that ratio to be satisfied BC has to be 1 so that AC would be 2.

Now let's assume the coordinates of C is $(x,y)$ .

To get it's coordinates, we use the section formula:

$(x,y)= (\frac{mx + nx_{1}}{m + n} , \frac{my + ny_{1}}{m + n})$

Where (m,n) is the (AB, BC)

Therefore we have

$(-1,2) = (\frac{1\times x + 1\times6}{1 + 1} , \frac{1\times y + 1\times3}{1 + 1})$

This gives:

$(-1,2) = (\frac{x + 6}{2} , \frac{y + 3}{2})$

$-1 =( \frac{x + 6}{2}$ and $2 = \frac{y + 3}{2})$

From there x = -8 and y = 1

Therefore the coordinates of C is (-8, 1).

Can some one solve this (squar roots)

Inessa05 [86]

Answer:

2 $\sqrt{6}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplifying the radicals

$\sqrt{96}$

= $\sqrt{16(6)}$

= $\sqrt{16}$ × $\sqrt{6}$ = 4 $\sqrt{6}$

$\sqrt{24}$

= $\sqrt{4(6)}$

= $\sqrt{4}$ × $\sqrt{6}$ = 2 $\sqrt{6}$

Thus

$\sqrt{96}$ + 2 $\sqrt{6}$ - 2 $\sqrt{24}$

= 4 $\sqrt{6}$ + 2 $\sqrt{6}$ - 4 $\sqrt{6}$ ← collect like terms

= 2 $\sqrt{6}$
