In a right triangle, the two legs measure 6 and 8 units. What is the length of the hypotenuse?

The circumference of a circle with a diameter of 10 cm is approximately:
Answer: 31.4 cm
Circumference = π × d = 3.14 × 10 ≈ 31.4 cm.
A line graph shows a company's sales increasing from $50,000 in January to $80,000 in June. What is the increase?
Answer: $30,000

What is the range of the data set: 12, 5, 19, 8, 15?
Answer: 14
Range = maximum - minimum = 19 - 5 = 14.
Two parallel lines are cut by a transversal. Which angle pair is always equal?

A pie chart shows that 30% of a budget goes to rent. If the total budget is $3,000, how much goes to rent?
