You have to divide both sides by 12 so 12f/12 =24/12 is f = 2
1) 2 : 1/2 = 4 (miles/hour)
2) 3 : 4 = 3/4 (hour)
Answer: you will walk 3 miles in 3/4 hour.
Answer:
Scarce demand / inflation
The word "scarce" means low on supplies or anything else.
Inflation is the term used when a price increases in the market.
These two terms together would best describe the higher demand.

Answer:
lateral area = 2320 m²
Step-by-step explanation:
The question wants us to calculate the lateral area of a square base pyramid. The square base pyramid has a side of 40 meters.The height is 21 meters.
Half of the square base is 40/2 = 20 meters . With the height it forms a right angle triangle. The hypotenuse side is the slant height of the pyramid.
Using Pythagoras's theorem
c² = a² + b²
c² = 20² + 21²
c² = 400 + 441
c² = 841
square root both sides
c = √841
c = 29 meters
The slant height of the pyramid is 29 meters.
The pyramid has four sided triangle. The lateral area is 4 multiply by the area of one triangle.
area of triangle = 1/2 × base × height
base = 40 meters
height = 29 meters
area = 1/2 × 40 × 29
area = 580
area of one triangle = 580 m²
Lateral area = 4(580)
lateral area = 2320 m²
