The answer is 90%. You get this answer by multiplying both the numerator and denominator by 5 so 18x5=90 and 20x5=100 giving you a fraction of 90/100 and a percentage of 90%.

Find the distance between these points.<br> R(-1,0), S(8,6)<br> V(26)<br> V(85)<br> 3V(13)

Thepotemich [5.8K]

Answer:

The distance is equal to $3\sqrt{13}\ units$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

$R(-1,0)\\S(8,6)$

substitute the values

$d=\sqrt{(6-0)^{2}+(8+1)^{2}}$

$d=\sqrt{(6)^{2}+(9)^{2}}$

$d=\sqrt{36+81}$

$d=\sqrt{117}\ units$

Simplify

$d=3\sqrt{13}\ units$

Using the digits 0 to 9, at most one time each, fill in the boxes to create a square, with one of the vertices at (2,3). Hint: 2

coldgirl [10]

Answer:

See explanation

Step-by-step explanation:

One vertex is at point (2,3).

Go 1 unit to the left and 5 units up, then the second vertex will be at the point (1,8).

Go 5 units to the right and 1 unit up, then the third vertex will be at point (6,9).

Go 1 unit to the right and 5 units down, then the fourth vertex will be at point (7,4).

Go 5 units to the left and 1 unit down to get into the vertex (2,3).

Since you always move one unit in one direction and 5 units in another direction, obtained quadrilateral will be a square.

See attached diagram for details.
