Divide 30 by 5. For example 30/5= 6. 5 lots of 6 make up 30, so that means 1/5 th of 30 is 6.
Answer:
Hello my friend! The answer is 1.75X10^-15
Step-by-step explanation:
If you multiply 2.5 x7 = 17.5
When we do the product of exponential terms with the same base, we can sum de exponents. In this case (-10) + (-6) = -16.
However, to scientific notation, we have to use 1.75
So, the final result wich were 17.5x10-16, will be "1.75x10^-15"

Answer:
Option (1). 6 inches
Step-by-step explanation:
Given question is incomplete; here is the complete question.
Tony needs 16-inch pieces of gold chain to make each of 3 necklaces. He has a piece of chain that is 4 1/2 feet long. How much chain will he have left after making the necklaces ?
Tony has a piece of chain = 4.5 feet long
≈ 4.5 × 12 inches
≈ 54 inches
Number of necklaces Tony wants to make = 3
Length of every piece of gold chain required for one necklace = 16 inches
Total length of gold chain required for 3 necklaces = 3 × 16 inches
= 48 inches
Length of remaining chain = 54 - 48 = 6 inches
Therefore, Option (1) will be the answer.
Answer:
k = $0.50
Step-by-step explanation:
The data that we have is:
Rocko paid: $12.50 for 25 tickets.
Louisa paid: $17.50 for 35 tickets.
Now, the question asks to find the constant of proportionality.
A proportional relation can be written as:
y = k*x
where k is the constant, and in this case, y is the price and x the number of tickets bought.
Then replacing with the values above, we have:
$12.50 = k*25
then:
k = $12.50/25 = $0.50
And the other data:
$17.50 = k*35
K = $17.50/35 = $0.50
So we have the same k in both cases, this means that the constant of proportionality is k = $0.50
