Each of them is correct as they all found the area of the base and then multiplied it be the height. I personally would have done the third option because I like having all the items written out.

5. Right

6. Right

7. Its not properly visible sorry for this.

8. Its wrong

$(\frac{1}{3} ) {}^{2} = \frac{1}{9}$

9. Right

10. Its wrong

$0.5 {}^{3} = 0.125$

11. Right

12. Its wrong.... Bcz square of minus is plus

$- 9 {}^{2} = 81$

13. Right

14. According to the BODMAS rule..

$15 - 7 \times 2 + {2}^{3}$

$15 - 14 + 8$

$1 + 8 = 9$

15.

$(11 - 8) {}^{2} - 2 \times 6$

$3 {}^{2} - 12$

$9 - 12 = - 3$

16.

$12 + \frac{ {9}^{2} }{3}$

$12 + \frac{81}{3}$

$12 + 27 = 39$

A farmer has 20 acres to plant in wheat and barley. He has to plant at least 15 acres. Wheat costs $200 per acre to plant and ba

Answer:

16 acres of barley only (no acres of wheat)

Step-by-step explanation:

A graph shows cost of planting puts an upper limit on planted area. The lower limit is provided by the requirement to plant at least 15 acres. The vertices of the feasible solution region are ...

(wheat acres, barley acres) = {(0, 15), (0, 16), (3, 12)}

The profit associated with these scenarios will be ...

for (0, 16): 16·350 = 5600

for (3, 12): 3·450 +12·350 = 1350 +4200 = 5550

To maximize profit, the farmer should plant 16 acres of barley.
