Answer:k=0.67
Step-by-step explanation:
1.625 rounded to the nearest hundredth is 1.63
Answer:

Step-by-step explanation:
Consider an element 
We know that 
Here, m and n are exponents and a is a base. Exponent refers to the no. of times a term is multiplied by itself. Another word for exponents is powers.
Other Properties of exponents:

Here, we are required to divide
by
.
Consider 
We will solve
separately.
Here,

So, 
3 times 5 times 2.5 = $37.5
3 x 5 =15
15 x 2.5 =37.5
37.5 x 2 = 75 for both of them
I don't know if this is right or not, but that's how I would solve it!
<em> Given that:</em> 100 copies = $3.10
<em>Find cost of 1 copy:</em>
1 copy = $3.10 ÷ 100 = $0.031
<em>Find the cost of 155 copies: </em>
155 copies = $0.031 x 155 = $4.81 (nearest hundredth)
Answer: $4.81
