Step-by-step explanation:
Plot the figure to better understand the problem
see the attached figure
we know that
If the figure is a rectangle
then

The area of the rectangle is equal to

where
B is the base
h is the height
the base B is equal to the distance AB
the height h is equal to the distance AD
Step 1
Find the distance AB
the formula to calculate the distance between two points is equal to


substitute the values

Step 2
Find the distance AD
the formula to calculate the distance between two points is equal to


substitute the values

Step 3
Find the area of the rectangle

we have

Answer:
$86
Step-by-step explanation:
first you gotta find the interest
4,600 * 1% = 46

your total cost is $86
A)
Increase %= (new # - old #)/old * 100
new= 8
old= 5
Increase %= (8-5)/5 * 100
=3/5 * 100
=0.60 * 100
=60% increase
B)
Decrease %= (old # - new #)/old * 100
new= 5
old= 8
Decrease %= (8-5)/8 * 100
= 3/8 * 100
= 0.375 * 100
= 37.5% decrease
ANSWER: a) 60% increase; b) 37.5% decrease
Hope this helps! :) Good luck on your test!!
<u>Answer:</u>
The sale price per piece of chicken was $0.69
<u>Step-by-step explanation:</u>
• We have to first calculate the price of 1 piece of chicken when 12 pieces cost $9.48.
Original price per piece = $9.48 ÷ 12
= $0.79

∴ Sale price per piece = $0.79 - $0.10
= $0.69
