• Estimating is a quick way of approximating the
  answer to a math problem. It can be used as a way
  to eliminate possible answer choices, or as a way
  to check for errors in a complex problem. Use
  estimation in the following problem to determine
  which of the answers is correct (do not use a
  calculator).
• What is 1486 1985?
• 2187
• 3276
• 3471
• 3897

round both numbers 1500 2000 3500 Is there
more than one answer close to 3500?

• Estimate to solve the following problem (do not
  use a calculator). 7,982 cars are parked in one
  parking lot and 5,261 cars are parked in a second
  lot. If 1,876 of these cars leave, how many cars
  remain parked?
• 13,243
• 11,367
• 9,858
• 3,385

round the numbers 8,000 5,000 2000
11,000 Is there more than one answer close?

• This is Quadrilateral UVWX. If triangles UYX and
  VZW are similar, which of the following is
  closest to the area of triangle VZW?
• 61 cm2
• 38 cm2
• 30 cm2
• 9 cm2

according to the online formula sheetthe area of
a triangle equals 1/2 times (base times
height) base 6.75 cm we have to find the
height, we will use the base of UYX to help if we
divide the base of VZW (6.75) by the base of UYX
(4.5), we find out that 6.75 is 1.5 times longer
than 4.5 since the triangles are similar, ZW then
must be 1.5 times longer than YX so to find our
height, we multiply 6 by 1.5, finally we can fill
in our formula Area 1/2 (6.75 times 9) Area
30.375

• What is the length of VW? (hint A squared B
  squared C squared)
• 11.15 cm
• 11.25 cm
• 11.75 cm
• 12.00 cm

from the last problem we know that ZW is 9 cm
long according to the pythagorean theorem, when
working with a right triangle, A squared B
squared C squared for our problem that
means 6.75 squared 9 squared VW
squared 45.5625 81 VW squared VW squared
126.5625 the square root of 126.5625 is 11.25, so
9 cm

The geologic time scale provides a system of
measurement relating stratigraphy to time that is
used by geologists, paleontologists and other
earth scientists to describe the timing and
relationships between events that have occurred
during the history of the earth. The table of
geologic time spans presented agree with the
dates and nomenclature proposed by the
International Commission on Stratigraphy, and
uses the standard color codes of the United
States Geological Survey. Evidence from
radiometric dating indicates that the Earth is
about 4.570 billion years old. The geological or
deep time of Earth's past has been organized into
various units according to events which took
place in each period. Different spans of time on
the time scale are usually delimited by major
geological or paleontological events, such as
mass extinctions. For example, the boundary
between the Cretaceous period and the Paleogene
period is defined by the CretaceousTertiary
extinction event, which marked the demise of the
dinosaurs and of many marine species. Older
periods which predate the reliable fossil record
are defined by absolute age. Each era on the
scale is separated from the next by a major event
or change.

• Which is the best definition for delimited?
• without limits
• removed all limitations
• marked the boundaries of
• none of the above

birth of Mr. Hebron

• Which choice has organisms listed in the proper
  order that they appeared on Earth?
• prokaryotes, humans, mulit-cellular life, animals
• prokaryotes, animals, land plants, humans
• multi-cellular life, land plants, animals, humans
• prokaryotes, land plants, animals, humans

looking at the clock shows that the legend has
them listed in order with oldest at the bottom.

SUPER FUN QUESTION OF THE WEEK
11
birth of Mr. Hebron

• Careful analysis of the results from radiometric
  dating leads scientists to believe that today is
  Mr. Hebrons birthday. According to the
  geological clock, which is true of Mr. Hebrons
  age?
• as suspected, he is indeed older than dirt
• he is among the first vertebrate land animals
• he witnessed the Cambrian explosion
• he roamed the earth with the dinosaurs

• The chorizo machine at Fiesta Mart produces 159
  mexican chorizo per hour. If the machine operates
  for 365 hours this month. How many chorizo will
  it produce?
• 48, 035
• 53,035
• 58,035
• 63,035

159 chorizo times 365 hours

• Use numbers from the previous question to help
  solve the problem. At the same rate, how many
  more hours will the chorizo machine need to
  operate to produce 75,000 chorizo?
• 107 hours
• 117 hours
• 427 hours
• 472 hours

75,000 chorizo divided by 159 per hour 471.69
hours to make 471.69 365

• Mi amigo Pablo runs the chorizo machine at Fiesta
  Mart (que es un muy buen hombre). Pablo works
  from 700am to 330pm 6 days per week. He takes a
  10 minute coffee break, a 30-minute lunch break,
  and a 10 minute siesta every day he works. If the
  chorizo machine still kicks out chorizo at a rate
  of 159 per hour, and it is running the entire
  time Pablo is working, how many chorizo will he
  make in one day?
• 1209 chorizo
• 1219 chorizo
• 1229 chorizo
• 1239 chorizo

700 to 330 is 8 1/2 hours minus 50 minutes for
breaks equals 7 hours and 40 minutes of work each
day 7.67 hours times 159 per hour
16

• At that same production rate, if Fiesta Mart pays
  Pablo 0.05 for each chorizo he produces, and
  Pablo works the same schedule every week, how
  much money would he earn in a 2-week pay period?
• 731.40
• 781.40
• 831.40
• 881.40

1219 chorizo times 12 days 14,628 chorizo made
in 2-weeks 14,628 times 0.05
