line segment with one endpoint at (2,5) is divided in the ratio 4:5 by the point (10,1). which coordinates could represent the o

rodikova [14]

Answer:

(20,-4)

Step-by-step explanation:

We are given;

One end point as (2,5)

Point of division as (10,1)

The ratio of division as 4:5

We are required to calculate the other endpoint.

Assuming the other endpoint is (x,y)

Using the ratio theorem

If the unknown endpoint is the last point on the line segment;

Then;

$\left[\begin{array}{ccc}10\\1\end{array}\right]$ = $\frac{4}{5} \left[\begin{array}{ccc}x\\y\end{array}\right]$ + $\frac{5}{9}\left[\begin{array}{ccc}2\\5\end{array}\right]$

Therefore; solving the equation;

$10=\frac{4}{9}x+\frac{10}{9}$

solving for x

x = 20

Also

$1=\frac{4}{9}y+\frac{25}{9}$

solving for y

y= -4

Therefore,

the coordinates of the end point are (20,-4)

The sales tax on a surfboard is $12. What is the percent of sales tax if it is $240

Mazyrski [523]

Answer: Percentage of sales tax will be 5%.

Step-by-step explanation:

Since we have given that

Original amount of a surfboard = $240

Sales tax on a surfboard = $12

So, Percentage of sales tax will be

$\frac{Sales\ tax}{Original\ price}\times 100\\\\=\frac{12}{24}\times 100\\\\=\frac{1}{2}\times 100\\\\=\frac{100}{2}\\\\=5\%$

Hence, Percentage of sales tax will be 5%.
