Answer: 120 ways
Step-by-step explanation:
Let's label the routes a, b, c, d, and e. The goal is to come up with as many unique permutations as possible.
1 route: a=1. one factorial (1!) =1*1=1
2 routes: ab, ba=2. 2!=1*2=2
3 routes: abc, acb, bac, bca, cab, cba=6. 3!=1*2*3=6
4 routes: 4!=1*2*3*4=24
5 routes: 5!=1*2*3*4*5=120 ways
Answer:
a)
Step-by-step explanation:
Square root of 75 (√75) is regarded as a surd function because the value inside the square root sign is not a perfect square. In that case the given value will be splitted into the product of a largest perfect square and a prime number as shown:
√75 = √3×25
√75 = √3×√25
√75 = √3 × 5
√75 = 5√3
a) Based on the above calculation, it can be inferred that his reasoning is incorrect. The value of 3 was supposed to be inside a square root not a whole number i.e √3 × √25
b) Since √75 = 5√3
√75 = 5 × 1.7321
√75 = 8.6605
√75 = 8.661 {to nearest thousand}
15 pounds of peanuts cost 45 dollars
how much does 1 pound of peanuts cost
ok
15 times (cost per pound)=45
represent cost per pound with 'w'
15 times w=45
15w=45
divide both sides by 15
w=45/15
w=3
cost is $3 per pound
