Answer:
c = 6P
Step-by-step explanation:
equation format: c = mP
c = the total cost Donna pays
m = the cost per pound of chocolate(6)
P = the amount of pounds Donna buys
Since we know the cost per pound is $6, we can input it into the equation format:
c = 6P
Now we have an equation that represents the total cost (c) that Donna pays for P pounds.
Answer:
Step-by-step explanation:
S.I= PTR/100
=9000*(15/12)*2/100
=90*5/2
=450/2
=225

Answer:
255 m
Step-by-step explanation:
From the given question, the surface of the water body is the reference point. And this point is assumed to be 0, so that any distance above it is positive, and any distance below is negative. This is synonymous to the number line system.
Thus,
For the aircraft, its height = +200 m
For the submarine, its depth = -55 m
So that the difference between the submarine and aircraft can be determined as;
200 - (-55)
= 200 + 55
= 255 m
The distance between the submarine and aircraft is 255 m.
