Answer:
- x = 375 square feet and y = 6,300 pounds.
Explanation:
The table is:
AIRPLANE LIFTING FORCE
Area of Wings Lifting Force
(square feet) (pounds)
125 1,875
150 2,250
175 2,625
250 3,750
x 5,625
420 y
The ratio of lifting force to the area is equivalent for all pairs in the table. What are the values of x and y?
<u>1. Calculate x:</u>
Ratio of lifting force to the area for the first pair (row):
Ratio of lifting force to area for the pair with x:
Set the proportion:
Equal the two ratios
Multiply both sides by 5,625 (multiplication property of equalities):
<u>2. Calculate y:</u>
You can use the same know ratio for the first pair: 125/1,875
And set the corresponding proportion, with y:
Invert both sides:
Multiply both sides by 420
The answer is x = 375 square feet and y = 6,300 pounds.
Answer:
wait is that a test if it is cheating
Step-by-step explanation:
well the first one go on the bottom 2 row secound one first row third first row but it is in happpy i am not reall good at math XD third last row forth very happy fifth on unhappy sixth very unhappy seven very unhappy eight on very happy i think i got it i did this before i just don't rembear but i tried
189.
3*1=34 --> split this into two parts. 3*1 is 3 and 3+1 is 4 so put them together and you get 34.
379.94 rounded to the nearest tenth is = 379.9
