Answer:
4.5 miles
Step-by-step explanation:
Joe wants to divide his 135-mile goal into 30 equal pieces. Each (daily) piece will be ...
... (135 mi)/(30 da) = 4.5 mi/da
The area of a triangle can be calculated as half the product of base length and height. We want the area to be no greater than 10 in².
a) (1/2)(4)(2x-3) ≤ 10
b) 4x -6 ≤ 10 . . . . . simplify
... 4x ≤ 16 . . . . . . . .add 6
... x ≤ 4 . . . . . . . . . divide by the coefficient of x
c) The maximum value of (2x -3) in is (2·4 -3) in = 5 in.
The triangle should be no more than 5 in high to have an area less than 10 in².
