Answer:

No. Hank wont be able to complete the hike.

Step-by-step explanation:

Time Available for hike = 4 hours

The expression which represents the time Hank needs to complete the hike is:

\text{time}=\frac{1}{2}d+\frac{1}{2}e

d is the distance in miles of the hiking trail. Since, Hank would like to hike 6 miles, d = 6

e is the elevation gain in thousands. Since, the trail hank will hike on has an elevation gain of 3000, so e = 3

Using these values in the expression, we get:

\text{Time}=\frac{1}{2}(6)+\frac{1}{2}(3)=4.5

This means Hank should allow him 4.5 hours or the hike. Since he has only 4 hours available, he wont be able to complete the hike. So the answer to this question is No.

Because of the commutative property of multiplication, it is true that
rewona [7]

Answer:

It is Commutative

Step-by-step explanation:

An operation ∆ is said to be Commutative if a∆b=b∆a ∀ a,b ∈ ℝ.

Given the operation ∆ defined by:

a∆b=a X b

a=\frac{3}{4}, b=4

a∆b=\frac{3}{4}X4

=\frac{3X4}{4}=3

Similarly, for the right hand side.

(\frac{4}{3})^{-1}=\frac{3}{4}

Therefore:

b∆a=4X \frac{3}{4}

=\frac{4X3}{4}=3

These are the two ways of solving this problem and we have in fact shown that the operation is commutative as:

a∆b=b∆a=3

could you possibly help me with this question? (its not part of a graded assignment, just a review from an online course of mine
Virty [35]

Let:

x = Pounds of walnuts in the mix.

Each pound of walnuts costs $0.80. thus x pounds of walnuts cost 0.8x dollars.

Each pound of cashews costs $1.25 and the mix will contain 8 pounds of cashews, so the cost is 8*$1.25 = $10

The total cost of the mix is, therefore: 0.8x + 10 dollars.

We are also given the pound of mix costs $1.00 and we have a total of 8 + x pounds, so the total cost of the mix is 1*(8 + x) dollars.

Equating both costs:

0.8x + 10 = 1*(8 + x)

Operating:

0.8x + 10 = 8 + x

Subtracting x and 10:

0.8x - x = 8 - 10

Simplifying:

-0.2x = -2

Dividing by -0.2:

x = -2/(-0.2)

x = 10

Answer: 10 pounds

Otrada [13]
Answer: C. Infinite
Explanation: (To explain this answer, I'll use 1 = 1) When you get 1 = 1 after doing an equation, this mean the answer is "all real numbers", which is the same term as "infinite" because it will always be true. Therefore, 0 = 0 will always be a true statement.
