Acoordinate grid is placed over a map and every unit represents 1 mi. the point at (3, 8) represents the location of the baseball stadium and the point at (7, –2) represents the location of the post office. to the nearest tenth of a mile, what is the distance between the baseball stadium and the post office?

(3,8), (7,-2)
distance as vector:
(7-3,-2-8)=(4,-10)

calculate vector length:
√(4²+10²)=√(16+100)=√(116)=10.77
so 10.77≈10.8 miles is the distance between the stadium and the post office

That would be , by distance formula:-

sqrt ((7-3)^2 + (-2-8)^2)
= sqrt  116

=  10.77  = 10.8 miles to neaREST 1/10

D - 47%

Step-by-step explanation:

1. add the total number of students in the chart who eats any kind of pizza (171+254+285+143 = 853)

2. add the total number of pepperoi pizza eaters (254+143 = 397)

3. Divide pepperoini pizza by the total (397/853 = .465 = 47%)
