Point p lies on the directed line segment from A (2,3) to B (8,0) and portions the segment in the ratio 2 to 1

Arturiano [62]

Answer:

The x-coordinate of point P is 6

Step-by-step explanation:

we have

A (2,3) and B (8,0)

we know that

Point P portions the segment AB in the ratio 2 to 1

$AP=\frac{2}{3} AB$

and

$AP_x=\frac{2}{3} AB_x$

where

AP_x represent the distance between the points A and P in the x-coordinates

AB_x represent the distance between the points A and B in the x-coordinates

$AB_x=8-2=6\ units$

$AP_x=\frac{2}{3} (6)=4\ units$

The x-coordinate of P is equal to

$P_x=A_x+AP_x$

where

A_x represent the x-coordinate of A

substitute the values

$P_x=2+4=6$

therefore

The x-coordinate of point P is 6

What is the least common denominator (LCD) of 12 and 23?

leva [86]

Answer: none of those, 276...?

Step-by-step explanation:

You need to know the least common denominator (LCD) of 12 and 23 if you want to add or subtract two fractions with 12 and 23 as denominators.

The least common denominator, also called lowest common denominator (LCD), of 12 and 23 is 276.

Here is a math problem example where you need to know the LCD of 12 and 23 to solve:

3/12 + 2/23 = ?

Step 1) Take the LCD and divide each denominator by it as follows:

276/12 = 23

276/23 = 12

Step 2) Multiply each nominator with the respective answers from Step 1:

3 x 23 = 69

2 x 12 = 24

Step 3) Put it all together to solve the problem:

69/276 + 24/276 = 93/276

= 3/12 + 2/23 = 93/276

It's that easy! Once again, the lowest common denominator (LCD) of 12 and 23 is as follows:

276

Simple Interest Rate Formula: $\displaystyle A = P(1 + rt)$

P is principle amount
r is rate
t is time

Step-by-step explanation:

Step 1: Define

Identify variables

P = 100

r = 4% = 0.04

t = 10

Step 2: Find Interest

Substitute in variables [Simple Interest Rate Formula]: A = 100(1 + 0.04 · 10)
(Parenthesis) Multiply: A = 100(1 + 0.4)
(Parenthesis) Add: A = 100(1.4)
Multiply: A = 140
