Using the Pythagorean theorem, we can calculate the distance from B to D.

60^2 + 50^2 = X^2

3600 + 2500 = x^2
6100 = x^2

X = SQRT(6100) = 78.1 m Round to 78 ( nearest meter)

If he walks a straight line from B to D, he would walk 78 meters.
 If he walks from B to C to D he would walk 60 + 50 = 110 meters.

Since 78 is less than 110, the straight line from B to D is shorter by 100-78 = 22 meters.

kirza4 [7]

Answer:

$250.15.

Step-by-step explanation:

Original price of chair:  $435

To find the sale price, multiply this $435 by (1.00 - 0.47), obtaining 0.53($435), or $230.55.

To find the total price after tax, multiply this $230.55 by (1 + 0.085), obtaining $250.15.

a number is equal to twice a smaller number plus 3. The same number is equal to twice the sum of the smaller number and1. How ma
NeX [460]

Answer:

There is NO solution

Step-by-step explanation:

Considering 'y' be the number

Considering x be the smaller number

As 'y' is equal to twice a smaller number plus 3.

so

y = 2x + 3

also

y is equal to twice the sum of the smaller number and 1.

so

y = 2x + 1

so the system of equations become

y = 2x + 3

y = 2x + 1

solving

\begin{bmatrix}y=2x+3\\ y=2x+1\end{bmatrix}

\mathrm{Subsititute\:}y=2x+1

\begin{bmatrix}2x+1=2x+3\end{bmatrix}

\mathrm{Refine\:}2x+1=2x+3

-2=0

-2=0\:\mathrm{\:is\:false,\:therefore\:the\:system\:of\:equations\:has\:no\:solution}

\mathrm{No\:Solution}

Therefore, there is NO solution.
