Answer:
Small gift: $2
Large gift: $7
Step-by-step explanation:
Let x represent cost of wrapping each small gift and y represent cost of wrapping each large gift.
We have been given that day one 41 small gifts were wrapped and 45 large were wrapped equaling $397.
We can represent this information in an equation as:

We are also told that day two 30 small gifts were wrapped and 47 large were wrapped equaling $389. We can represent this information in an equation as:
From equation (1), we will get:

Upon substituting this value in equation (2), we will get:










Therefore, cost to wrap a large gift is $7.
Upon substituting
in equation
, we will get:




Therefore, cost to wrap a small gift is $2.
Answer:
$12

Answer:
<u>v = √(LT/m)</u>
Step-by-step explanation:
Given :
Multiply both sides with L :
- T × L = mv²/L x L
- LT = mv²
Divide both sides by m :
- LT × 1/m = mv² × 1/m
- LT/m = v²
Take the square root on each side :
- √v² = √(LT/m)
- <u>v = √(LT/m)</u>
