Transcript

  • 1. • Solve problems involving scale drawings.• scale drawing• scale model• scale• scale factor
  • 2. Use a Map ScaleMAPS What is the actual distance betweenDaytona Beach and Orlando?Step 1 Use an inch ruler to find the map distance between the two cities. The map distance is about or 1.75 inches.
  • 3. Use a Map ScaleStep 2 Write and solve a proportion using the scale. Let d represent the actual distance between the cities. 0.5 • d = 17.3 • 1.75 Cross products 0.5d = 30.275 Multiply. Divide each side by 0.5.
  • 4. Use a Map Scale d = 60.55 Simplify.Answer: The actual distance between Daytona Beach and Orlando is about 61 miles.
  • 5. MAPS The distance on a map has a scale of0.5 inch = 14 miles. The measured distancebetween West Palm Beach and Ft. Lauderdale onthe map is 1.5 inches. What is the actual distancebetween these two cities?A. 21 milesB. 28 milesC. 42 milesD. 56 miles
  • 6. Use a Scale ModelMURALS An artist is painting a large mural offlowers on the side of a school. If she uses thescale 4 inches = 1 inch, how large will the muralpainting of a rose bloom be if it is incheshigh?
  • 7. Use a Scale Model 4 • 6.25 = 1 • h Cross products 25 = h Multiply.Answer: The mural painting of the rose bloom will be 25 inches high.
  • 8. FURNITURE A full-size model is being created froma child-size rocking chair which has a height of 15inches. If the scale to be used is4 inches = 1 inch, what is the height of the model?A. 40 in.B. 55 in.C. 60 in.D. 80 in.
  • 9. Find a Scale FactorFind the scale factor of a blueprint if the scale is inch = 3 feet. Convert 3 feet to inches. Divide out common units. Rewrite the division sentence as a multiplication sentence. Simplify.
  • 10. Find a Scale FactorAnswer: The scale factor is .
  • 11. Find the scale factor of a blueprint if the scale is inch = 5 feet.A.B.C.D.
  • 12. Construct a Scale ModelBUILDINGS An architect is making a model of anapartment building that is 150 feet tall. Find thescale if the model of the apartment building is3 inches tall. Using this scale, find the height of themodel of a house nearby if the actual height is25 feet. Divide the numerator and denominator by 3 so the numerator equals 1.
  • 13. Construct a Scale ModelThe scale is 1 inch = 50 feet. Using this scale, findthe height of a model of a nearby house. 1 • 25 = 50 • x Find the cross products. 25 = 50x Multiply. =x Divide by 50.
  • 14. Construct a Scale ModelAnswer: The scale is 1 inch = 50 feet. The height of the model of the nearby house is inch.
  • 15. PARKS Steve is making a model replica of a parknear his house. One of the trees in his model is 3inches tall and represents a tree that is actually15 feet tall. Find the scale of the model and thenusing this scale, find the actual height of anothertree in his model that is 2 inches tall.A. 1 inch = 12 feet; 24 feetB. 1 inch = 5 feet; 13 feetC. 1 inch = 5 feet; 10 feetD. 1 inch = 3 feet; 6 feet
