First you need to know that square means multiplicatin by itself to itself so square of 20 means 20×20=400
Answer:
The price of the drinks is $ 1.5 and the price of the bag of popcorn is $ 6.75
Step-by-step explanation:
We can solve by means of a 2x2 equation system, assuming that the question is the price of each product
We have to:
"x" price of drinks
"and" price of the bag of popcorn
9 * x + 4 * y = 40.5
3 * x + 5 * y = 38.25 => x = (38.25 - 5 * y) / 3
replacing:
9 * (38.25 - 5 * y) / 3 + 4 * y = 40.5
114.75 - 15 * y + 4 * y = 40.5
-11 * y = 40.5 - 114.75
y = -74.25 / -11
y = 6.75
now for x:
x = (38.25 - 5 * 6.75) / 3
x = 1.5
So the price of the drinks is $ 1.5 and the price of the bag of popcorn is $ 6.75
1 ft= 12 inches
24 × 18 = 432
432 × 12 = 5184
5184 cubic inches of water
You have to ask yourself “how many half hours segments are in 2 hours?” The answer is 4. Now, since you want to find out how many miles the boat can travel in half an hour, divide 27 by 4 (because there are four half hours in 2 hours). 27 divided by 4 equals 6.75. The boat travels 6.75 miles in half an hour.
