Answer:
D) 12,656
Step-by-step explanation:
First of all, as they have given us 3 quantities of plants in 1/2 an acre, we can work out the average amount of plants in 1 whole acre.
In the first 1/2 acre there were:
In the second 1/2 acre there were:
In the third 1/2 acre there were:
to work out the average, we add all these together then divide them by 3 (as there are 3 examples)
291 + 327 + 286 = 904
904 ÷ 3 = 301.3 (this is the average amount of plants in every 1/2 acre.) If we multiply this answer by 2 we will get the average amount of plants in every acre.
301.3 x 2 = 602.67 (average plants in every 1 acre) multiply by total acres (21) for your answer
602.67 x 21 = 12656 average plants in total

11.5/100 (320)
184/5 (decimal:36.8)
hope this helps!
No because ab can be divided by a and b.
First, you make 9 into a fraction which would become 36/4
then, subtract 9/4 from both sides so that would give you 3/4x = 27/4
then divide each side by 3/4 (same thing as multiply by its reciprocal) and that would give you x=9
Answer:
$60.8
Step-by-step explanation:
Twenty percent of 76 is,
→ 20% of 76
→ (20/100) × 76
→ 1520/100
→ [ $15.2 ]
The reduced price of the item is,
→ 76 - 15.2
→ [ $60.8 ]
Hence, the price is $60.8.
