Answer: Observational study
Step-by-step explanation: I just took the test
The area covered by corn is x
The area covered by wheat is (x+480)
After 80% of wheat was collected, the new area was:
20/10(x+480)
=1/5(x+480)
After 25% of the corn was collected, the new area was:
75/100x
=3/4x
New area equation will be:
(3/4)x=1/5(x+480)+300
(3/4x)=(1/5)x+96+300
solving for x we get:
11/20x=396
x=720
thus the original area of corn was 720 acres
Original area of wheat was 720+480=1200 acres
Answer:
34
56/19
6
Step-by-step explanation:
∵ z = 8
∴ 4(8) + 8 - 6 =34
∵ x = 3
∴ 7z /(4 + 5x) = 7(8) ÷ (4 + 5 × 3) = 56 ÷ 19 = 56/19
∵ y = 12
∴ y² ÷ 3z = (12)² ÷ 3(8) = 144 ÷ 24 = 6
Answer:
6 pounds
Step-by-step explanation:
6 times 4 is 24. so it has to be 6 since you have 4
