1620-60=1560 to share between them (since Catherine has 60 more). 1560/2=$780
Answer: x = 40 and y = 40
Step-by-step explanation:
We can write the equation for the area as: x*y = 1600
We can write the equation for the perimeter as: 2x + 2y = 160
An easy way to solve a question like this is to graph both equations on a graphing calculator, if you don't have one on you you can use Desmos
Graph both: y = 1600/x
and
y = 80 - x
Turns out you get x = 40 and y = 40

Answer:
Single Equivalent Discount % on final price = 41.58%
Explanation:
The grill was initially priced at $769.99 and was discounted to $550.54 which is 28.5% ((550.54/769.99)-1)*100
and then further discounted by 18.3% ((449.79/550.54)-1)*100 to $449.79.
but if we want to get the single discount rate for $449.79 (final price), we have to compare it with very first original price of $769.99 so the formula will be:
((449.79/769.99)-1)*100 = 41.58% which shows the actual discount % versus the original price of the grill.
Step-by-step explanation:
rounding off of 123.5201 is 123.5
rounding off of 424.9832 is 425
rounding off of 675.0608 is 675.1
rounding off of 1247.0057 is 1247
rounding off of 5653.5974 is 5653.6
here we have rounded off to first decimal place
one point to note that we can just approximate to get the rounded off value. We have to follow several rules, like we should increase the last digit to be retained by one when the digit following it is greater than 5 and we should not
change the last digit if the digit following the last digit to be retained is less than five
