The ordered pair that represents the halfway point between Mary's home and the grocery store is (1, 4)
The midpoint (a, b) between two linear points 
and 
is calculated as:
On a map, Mary's house is located at (−3, 1) and the grocery store is located at (5, 7).
Substitute these values into the mid-point formulae

Answer: $2.72
Step-by-step explanation: Multiply the amount of strawberries in this case 3.4 by the price per unit in this case $0.80 per pound.
A because you are multiplying 3/4 by 1/2, you make the product smaller than 3/4
B beacue any number multiplied by one remains that number, since you are multiplying 3/4 by 1 it will remaim 3/4
C because the number multiplied by 3/4 is larger than 1 ( 3/2 = 1 1/2) the product will be larger than 3/4
If you can find your way through all the smoke of the definition,
you find that an increase of 10 times the intensity is an increase
of 10 dB.
Next, if you can find your way over, under, around, and through
all the speeds and distances of the vehicles, you'll find that you
don't need them. Right in the middle of the pile, it says "intensity
10 times that of ...". That right there tells you that the sound of
the truck is 10 dB louder than the sound of the car.
So the car is 70 dB (asked for, and then given), and the truck is 80 dB.
