Plz help me and thanks so much for ur help

Iceland is a country that is located right above a mid-ocean ridge. This actually makes the country being divided in two parts geologically speaking, as the western half is part of the North American plate, while the eastern half is part of the Eurasian plate.

Iceland has formed because of intense volcanic activity at the mid-ocean ridge in the North Atlantic Ocean. As more and more magma has been propelled at the divergent boundary, the mid-ocean ridge has been growing in size, and over time it gradually became so high that it came out above the surface of the water.

The volcanic activity has continued, and it still is, and the volcanic eruptions constantly provide new lava flows, which create new crust, thus solidify the island and make it a long lasting one, not allowing the erosion to gradually level it and destroy it.

Let's solve your equation step-by-step.

2a−8a=12−8a

Step 1: Simplify both sides of the equation.

2a−8a=12−8a

2a+−8a=12+−8a

(2a+−8a)=−8a+12(Combine Like Terms)

−6a=−8a+12

−6a=−8a+12

Step 2: Add 8a to both sides.

−6a+8a=−8a+12+8a

2a=12

Step 3: Divide both sides by 2.

2a

2

=

12

a=6

Answer:

b. 15% nitrogen, 30% phosphorus, 10% potash (potassium)

Explanation:

The marks on the packages of the fertilizers are telling us what is their content. The system used id the N-P-K ratio. The N-P-K ratio is giving us information about the chemicals from which the fertilizer is made, and the percentage of each of them. N stands for nitrogen, P stands for phosphorus, and K stands for potash (potassium). In this case we have 15-30-10. This will mean that the percentage of nitrogen is 15%, the percentage of phosphorus is 30%, and the percentage of potash (potassium) is 10%, meaning that we have a fertilizer that is high on phosphorus content.

Final answer:

The fertilizer grade 15-30-10 corresponds to 15% nitrogen, 30% phosphorous, and 10% potash (potassium), respectively. These nutrients play crucial roles in plant health, growth, energy storage and transfer, along with various cellular functions. The fertilizer type should be chosen based on the plant's specific needs and the existing nutrients in the soil.

Explanation:

The numbers on a bag of fertilizer, or the fertilizer grade, represent the percentages of Nitrogen (N), Phosphorous (P), and Potassium (K), respectively. So, in the case of a 15-30-10 fertilizer, the correct combination would be b. 15% nitrogen, 30% phosphorous, 10% potash (potassium).

Nitrogen is crucial in many of a plant’s biological processes and is a major component of proteins, nucleic acids, chlorophyll, and other cell components. Phosphorus helps plants store and transfer energy. Potassium, also known as potash, is important for overall plant health due to its role in the functioning of cell membranes and its involvement in photosynthesis as well as other cellular processes.

Thus, the composition of a fertilizer should be tailored to the nutritional needs of the specific plant and the nutrient content of the soil in which it is being grown.
