Answer:
Step-by-step explanation:
The Alyssa will spend $14.915 for wrap a ribbon around the gift, if a ribbon costs $0.50 per inch.
Step-by-step explanation:
The given is,
A circular gift has a 4.75 inch radius
Ribbon that costs $0.50 per inch
Step:1
Formula to calculate the perimeter of circle,
......................(1)
Where, r - Radius of circle
From the given,
r = 4.75 inches
Equation (1) becomes,
(∵
= 3.14)
Perimeter, P = 29.83 inches
Step:2
Cost for wrap the ribbon to around the circular gift,
= Perimeter of circular gift × ribbon cost per inch
= (29.83 × 0.50)
= $14.915
Cost for wrap the ribbon to around the circular gift = $14.915
Result:
The Alyssa will spend $14.915 for wrap a ribbon around the gift, if a ribbon costs $0.50 per inch.
Answer:
(2,4) is a solution to this system of equations
Step-by-step explanation:
Given system of equation are
To find the solution of the given system of equations
To Check that (2,4) is a solution to this system or not
Solving equations (1) and (2)
From equation (1) and y=2x
Now substitute y=2x is equation (2)
10-5x=0
-5x=-10
Substitute x=2 in equation (1)
y=2x
y=2(2)
Therefore y=4
Therefore the solution is (2,4)
Therefore (2,4) is a solution to the system of equations.
