Apply the Pythagorean Theorem to find the distance between points B and C. A) 18 units B) 55 units C) 64 units D) 73 units
nadya68 [22]

Answer:

BC=\sqrt{73}

Step-by-step explanation:

Notice that A, B, and C constitute the vertices of a right angle triangle, with the right angle at the vertex A.

If we count the number of squares separating B and A (one of the legs of the right angle triangle) we find 8 units.

If we count the number of squares separating C from A (the other leg of the right angle triangle), we get: 3 units.

Then, we apply the Pythagorean theorem to find that length of the triangle's hypotenuse which is the segment BC:

BC=hyp=\sqrt{8^2+3^2} =\sqrt{64+9} =\sqrt{73}

Find the distance between the points given.<br><br> (0, -6) and (9, 6)
Leya [2.2K]
AB=9
AC=`12
BC=x=?
ABC is a triangle with 90 degree
x2=(9)2+(12)2
x2=81+144
x2=225
x=15 so the distance between the points given is 15

Regina, courtney, and Ellen hiked around bear pond. Regina hiked 7/10 of the distance in an hour. Ellen hiked 3/8 of the distanc
Kitty [74]
7/10 > 3/8

I found this by first finding a common denominator, so for this it will be 40. 10 can go into 40 four times, so you do 7x4 and that is 28, so 7/10 is 28/40.
3/8 is 15/40 because 8 goes into 40 five times, so you do 5x3 which is 15, so the fraction is 15/40. 15/40 is less than 28/40 because 28 > 15
