#1 - a) 11.4018
#2 - d) 7.62
#3 - a) 10.7238
#4 - b) 6.57
Explanation
#1 - The initial guess is 11.4022. We first divide 130 by this guess:
130÷11.4022 = 11.40130852
We now average this number with the initial guess:
(11.40130852 + 11.4022)/2 ≈ 11.4018
#2 - The initial guess is 7.8. We divide 58 by this guess:
58÷7.8 = 7.435897436
We now average this number with the initial guess:
(7.435897436 + 7.8)/2 = 7.617948718 ≈ 7.62
#3 - The initial guess is 10.7262. We divide 115 by this guess:
115÷10.7262 = 10.72141112
We now average this number with the initial guess:
(10.72141112 + 10.7262)/2 = 10.72380556 ≈ 10.7238
#4 - The initial guess is 6.9. We divide 43 by this guess:
43÷6.9 = 6.231884058
We now average this number with the initial guess:
(6.231884058+6.9)/2 = 6.565942029 ≈ 6.57
Answer:
8.65 in fraction form 8 13/20
Step-by-step explanation:
Kenyan = k
$3.50 per pound
Sri Lankan = s
$5.60 per pound
6lbs of blend
$28.35
s+k = 6
3.50k + 5.60s = 28.35
where:
k = lbs of kenyan
s = lbs of Sri Lankan
Solve the system
s+k = 6
3.50k + 5.60s = 28.35
solve the first equation for s:
s = 6-k
Replace in the second equation:
3.50k + 5.60 (6-k) = 28.35
3.50k + 5.60(6)+ 5.60(-k) = 28.35
3.50k + 33.6 - 5.60k = 28.35
3.50k - 5.60k = 28.35-33.6
-2.1k= -5.25
k= -5.25/-2.1
k= 2.5 lbs
Replace k on any equation and solve for s
s+k= 6
s+ 2.5 = 6
s= 6-2.5
s= 3.5 lbs
