Answer:
father = 32 s = 5 y/o
Step-by-step explanation:
f s = 160 ====> s = 160/f
f+4 = 4 ( s+4)
f + 4 = 4 (160/f +4)
f + 4 = 640/f + 16
f^2 + 4f = 640 + 16 f
f^2 -12f - 640 = 0 Use Quadratic formula to find f = 32 then s = 5
Answer:
Step-by-step explanation:
Given:
for x≤1400; N = 5
So, Δx = 
=∑C(a + nΔx).Δx
=C(0)Δx + C(280)Δx + C(560)Δx + C(840)Δx + C(1120)Δx
= Δx[C(0) + C(280) + C(560) + C(840) + C(1120)]
= 280[49 + 42.616 + 34.664 + 25.144 + 14.056]
=280[165.48]
=46334 approx

Answer:
<h2>
y=0.35m+50</h2>
Step-by-step explanation:
Step one:
given data
the daily fee= $50
cost per mile driven =$0.35
Let m = the number of miles
let y be the total cost
Step two
Required
the expression for the total cost is
An algebraic expression that shows the amount he will pay for the van. is
<em>y=0.35m+50</em>
the correct answer is:
Carlos could have written 0.333, 0.334, and 0.3335.
