Alina is able to swim at a rate of about 2.5 miles per hour. talia is able to swim at a rate of 1.8 meters per second. which statement comparing the two swimmers is accurate? 1 mile 1,609 meters alina swims about 0.7 miles per hour faster than talia. talia swims about 0.7 miles per hour faster than alina. alina swims about 1.5 miles per hour faster than talia. talia swims about 1.5 miles per hour faster than alina.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

a ≈ 172.05

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
