A 6-kg bag of fertilizer covers a rectangular area of 2.5 m by 5.0 m.
1 answer:
Answer
Given,
Mass of bag = 6 Kg
Area covered by the bag = 2.5 x 5 = 12.5 m²
a) Bags required to cover area = 7.5 x 10.2
= 76.5 m²
Number of bags, N =
N = 6.12 = 7 (approx.)
7 Bags of 6 Kg fertilizers will be needed to cover the area.
b) Cost of 6 Kg fertilizers = $15.50
Cost of 7 bags of 6 Kg fertilizers = 7 x $15.50
= $108.50.

Answer:
The expression for number of sandwiches is
9 small sandwiches can be made.
Step-by-step explanation:
Given:
Length of party-sized sandwich (l) = 3/4 yard
Length of each small sandwich (s) = 1/12 yard
Now, let the total number of small sandwiches be 'n'.
Now, sum of all the lengths of small sandwiches will be equal to the length of the party-sized sandwiches.
Therefore, framing in equation form, we have:
Length of large sandwich = Length of small sandwich × Total number of small sandwiches.
Now, plug in the given values and solve for 'n'. This gives,
Therefore, 9 small sandwiches can be made.
