a stalk of corn grew 42 inches in a week. find the unit rate in inches per day.

6 inches per day

Step-by-step explanation:

divide 42 by 7, since there are 7 days in a week

The unit rate in increase per day is 6 inches/day

Step-by-step explanation:

To solve for the unit rate in inches per day

Firstly we understand that a week has 7days in it

So if the stalk grows at 42inches per week

In a day it will grow at a rate of

=42/7

=6 inches per day

So each day it grows at 6 inches

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

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
