The hardest natural substance on Earth is **diamond**. On the Mohs scale of mineral hardness, diamond is rated at 10, which is the highest possible value on this scale. This extreme hardness is due to its rigid crystal lattice structure, where each carbon atom is covalently bonded to four neighboring carbon atoms in a strong three-dimensional network. While other extremely hard materials like **aggregated diamond nanorods** (a lab-grown form of carbon) have been developed and may surpass diamond in some tests, diamond remains the hardest *naturally occurring* substance found in nature. </assistant>

The capital of Australia is **Canberra**. It is located in the **Australian Capital Territory** (ACT), a federal territory specifically established to serve as the nation's capital. Canberra was chosen as the capital in 1913 as a compromise between Sydney and Melbourne, the two largest cities at the time, to ensure neither had an unfair advantage. The city was designed by American architect Walter Burley Griffin and officially opened in 1913. </assistant>

I'll solve this step by step. **Given:** - House purchase price: $80,000 - Repair costs: $50,000 - Value increase from repairs: 150% **Step 1: Calculate the total investment** Total investment = Purchase price + Repair costs Total investment = $80,000 + $50,000 = $130,000 **Step 2: Calculate the value increase** The repairs increased the house value by 150% of the original value. Value increase = 150% × $80,000 = 1.5 × $80,000 = $120,000 **Step 3: Calculate the new house value** New value = Original value + Value increase New value = $80,000 + $120,000 = $200,000 **Step 4: Calculate the profit** Profit = New value - Total investment Profit = $200,000 - $130,000 = $70,000 **Answer:** Josh made a profit of **$70,000**. </assistant>

I'll solve this step by step. **Given:** - Ducks lay 16 eggs per day - Janet eats 3 eggs for breakfast - She uses 4 eggs for muffins - She sells remaining eggs for $2 each **Step 1: Calculate total eggs used** - Eggs for breakfast: 3 - Eggs for muffins: 4 - Total used: 3 + 4 = 7 eggs **Step 2: Calculate remaining eggs to sell** - Remaining eggs: 16 - 7 = 9 eggs **Step 3: Calculate daily earnings** - Earnings: 9 eggs × $2 per egg = $18 **Answer:** Janet makes **$18** every day at the farmers' market. </assistant>

The capital of Australia is **Canberra**. It's located in the **Australian Capital Territory (ACT)**, a self-governing territory in the country's capital region. Canberra was purpose-built to serve as the capital, chosen in 1913 as a compromise between the competing cities of Sydney and Melbourne.

I'll work through this step by step to find Sam's total profit. **Step 1: Calculate total cost** - Sam bought 12 boxes (a dozen) - Each box costs $10 - **Total cost = 12 × $10 = $120** **Step 2: Calculate total number of highlighters** - Each box contains 30 pens - **Total pens = 12 × 30 = 360 pens** **Step 3: Calculate number of packs made** - He rearranged them into packs of 6 pens each - **Number of packs = 360 ÷ 6 = 60 packs** **Step 4: Calculate total revenue** - He sold each pack for $5 - **Total revenue = 60 × $5 = $300** **Step 5: Calculate profit** - **Profit = Total revenue - Total cost** - **Profit = $300 - $120 = $180** Sam made a profit of **$180** in total. </assistant>
