Answer:
The consultant's advice will reduce soil degradation and increase organic matter content in soil
Explanation:
In this scenario the present practice by the farmer of burning crop residue and tilling results in soil degradation and loss of organic matter.
Burning on the farm leads to loss of crop nutrients such as nitrogen and organic matter. It also causes environmental pollution of air, land, and water when carbon, nitrogen, and sulphur by-products are released to the atmosphere.
Tillage is the practice of turning the top 6 - 12 cm of soil when preparing for planting. This practice reduces water holding capacity of soil, accelerates nutrient loss, and degrades soil structure.
So if the farmer stops burning crop residue and practices zero tillage it will result in less environmental pollution, reduce soil degradation, and increase soil nutrients especially organic matter
Jarell is grocery shopping for his bbq cookout this weekend. he is grilling 1313lb. burgers and expects about 20 people. 6.667 lbs. of ground beef should be purchased.
Jarrell should purchase 7 lbs of ground beef.
Number of attendees = 20
Fraction of burger per person = 1/3 lbs
Total fraction of burger required to feed 20 persons :
Number of attendees × fraction per person
20 × 1/3 = 6.667.
Grilling is a cooking method that applies dry heat to the surface of food, usually from the top, bottom, or sides. Grills typically use large amounts of direct radiant heat and are typically used to quickly cook meat and vegetables.
Almost all types of grilling on gas and/or charcoal grills can be divided into three cooking methods: direct, indirect, or combination. As the name suggests, method differences are determined as follows.

Answer:
The correct answer is the letter a. "Make more than 20 wedding cakes a month."
Explanation:
To maximize profit the marginal price of each cake must equal the marginal cost of each cake. The marginal cost is 300 and the marginal price is 5000/20 = 250. The marginal price of each cake (250) is less than the marginal cost of each cake (300), so Laura needs to make more than 20 cakes to increase her revenue and maximize her profit.
Answer and Explanation:
According to the scenario, computation of the given data are as follow:-
We assume that
X = No. of children
Y = Standard type
Z = Executive type
So,
5x + 4y + 7z = 185.........(1)
3x + 2y + 5z = 115.........(2)
2x + 2y + 4z = 94
x + y + 2z = 47.........(3)
Equation (2) multiply by 2
6x + 4y + 10z = 230
From equation (1) to (2)
5x + 4y + 7z = 185
6x + 4y + 10z = 230
-x + 0 - 3z = -45
x + 3z = 45.......(4)
Equation (3) multiply by 4
4x + 4y + 8z = 188
From equation (1) to (3)
5x + 4y + 7z = 185
4x + 4y + 8z = 188
x + 0 - z = -3
- x + z = 3……(5)
From equation (5) to (4)
x + 3z = 45
-x + z = 3
4z = 48
Executive type = Z = 48 ÷ 4 = 12
Z = 12 in equation (5)
-x + 12 = 3
x = 9 (children type)
x=9, z=12 in equation 1
5x + 4y + 7z = 185
5 × 9 + 4 × y + 7 × 12=185
45 + 4 × y + 84 = 185
4y = 56 ÷ 4
Y= 14(Standard type)
