Boat A is docked at (4.2, −2) and Boat B is docked at (−5.2, −2). The boats are units apart.

9.4 units

Step-by-step explanation:

Step one:

given data'

We are given the coordinates

x1=4.2

x2=-5.2

y1=-2

y2=-2

Required

The distance between the points

Step two:

The expression for the distance is

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((-5.2-4.2)²+(-2+2)²)

d=√((-9.4)²

d= √88.36

d= 9.4 units

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.

the answer is 99.
