After learning the midpoint construction Sally realizes that she could determine one fourth the length of a segment how could sh
Viefleur [7K]
The midpoint of two points is the point which divides the line segment joining the two points into two equal parts.

Suppose, we have a line segment AB with a point C, between point A and point B such that the distance AC is equal to the distance CB, then we say that point C is the midpoint of line AB.

Suppose, we have another point D between point A and point C, such that the distance AD is equal to the distance DC, then we say that point D is the midpoint of AC.

Notice that point D is a fourth of line segment AB.

Thus, AD is <span>one fourth the length of segment AB.

Therefore, one fourth the length of a segment can be obtained by evaluating the midpoint of the midpoint of the line segment.

Write an expression that can be used to multiply 6 times 198 mentally
Zigmanuir [339]
I would half 198, get
99 and add a 0, this is how you multiply by 5 in your head

198*5 = 990
990 + 200 = 1190 - 2
= 1188

Alternatively we can round 198 to 200: then multiply by 6

200*6 = 1200

Then We subtract the 6 "2's" that we added

1200 - 12 = 1188


The expression for this is:
(6*200) - (6 * 2)

R(-9, 4) and S(2,-1); Find T.
madreJ [45]

Answer:

12.083 units

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

Where

(x_1,y_1) = (-9,4)

(x_2,y_2) = (2,-1)

Replacing these values in the distance formula

D =\sqrt{(-9-2))^2+(4-(-1))^2}

D =\sqrt{(-11)^2+(5)^2}

D =\sqrt{121+25}

D =\sqrt{146}

D= 12.083

Hence the distance is 12.083 units
