Do 2x6=12×3 since there is 3 packages 2 rows and 6 in each row
(184-94)/5=18
This means that she fills up 18 liters every minute. Thus she will be done in->
184(original amount)+(2 minutes (time passed during first data point)*18(rate of water)=184+36=220
To find the total time taken we divide 220 by 18 which is 220/18=12 2/9
Answer:
The side length of the original square was 6 inches
Step-by-step explanation:
we know that
The area of a square is

where
b is the length side of the square
Let
x ---> the length of the original square
The area of the original square is

The length of the smaller square is

The area of the smaller square is

The area of the smaller square is 1/4 the area of the original square
so

solve for x

Multiply by 4 both sides


Solve the quadratic equation by graphing
using a graphing tool
x=2, x=6
see the attached figure
The solution is x=6 in
Remember that the solution must be greater than 3 inches (because Stacey cuts 3 inches off of the length of the square and 3 inches off of the width)
therefore
The side length of the original square was 6 inches
The shelf should sell for $235.20.
Marking the price up by 60% means taking 160% of the cost:
160% = 160/100 = 1.6; 1.6(147) = 235.20
