5/12<8/10
Answer:
x=2,3
Step-by-step explanation:
(x- 2) (x - 3) =0
Using the zero product property
x-2 =0 x-3 =0
x-2+2=0+2 x-3+3 =0+3
x=2 x+3
B 6
C 3
The base is 6.
In order to find this, we can set the legs equal to each other since legs have the same length in an isosceles triangle.
x + 1 = -x + 7
2x + 1 = 7
2x = 6
x = 3
Now that we have the value for x, we can plug into the equation to get the value for the base.
3x - 3 = base
3(3) - 3 = base
9 - 3 = base
6 = base

These are 8 questions and 8 answers.
Question 1) a deep sea exploring ship is pulling up a diver at the rate of 25 feet per minute. The diver is 200 feet below sea level. How deep was the diver 10 minutes ago?
Answer: 450 feet below see level ( -450 feet)
Explanation:
i) pulling up rate: 25 feet / minute
ii) number of feet ascended
iii) number of feet ascended in 10 minutes: 25 feet / minute × 10 minutes = 250 feet
iv) current deep: - 200 feet
v) deep 10 minutes ago: -200 feet - 250 feet = - 450 feet. Which means 450 feet below sea level.
Question2) if it is 5 outside and the temperature will drop 17 in the next six hours, how cold will it get?
Answer: - 12 (12 below zero)
Explanation:
i) Future temperaure = current temperature - decrease in temperature
ii) Future temperature = 5 - 17 = - 12, which means 12 below zero
Question3) Josie has $47 left on her checking account. If she writes a check for $55 what will Josie's balance be?
Answer: - $ 8 (she will owe 8$)
i) Balance = current balance - new checks
ii) Balance = $ 47 - $ 55 = - $8 (she will owe $ 8)
Question 4) Joe is playing a game with a regular die. If the number that turns up is even, he will gain 5 times the number that comes up. If it is odd, he will lose 10 times the number that comes up. He tosses a 3 express the results as an integer.
Answer: he will lose 30.
Explanation:
i) 3 is odd
ii) 1Therefore, the result is that he will lose 10 times the number that comes up
⇒ Loss = 10 × 3 = 30
Question 5) it will be -12 tonight. The weatherman predicts it will be 25 warmer by noon tomorrow. What will the temperature be by noon tomorrow?
Answer: 13
Explanation:
i) Current temperature: - 12
ii) Change foreseen: + 25 (increase)
iii) Foreseen temperature = - 12 + 25 = 13
Question 6) the average temperature at the South Pole is -45 F. The average temperature on the equator is 92 F. How much warmer is the average temperature on the equator than at the South Pole?
Answer: 137 F
Explanation:
i) Temperature at the South Pole = - 45F
ii) Temperature on the Equator = 92 F
iii) Difference in temperature = temperature on the Equator - temperature and the South Pole
iv) Difference in temperature = 92F - (-45F) = 92F + 45F = 137F
Remember the law of signs: ( - ) × ( - ) = +
∴ It is 137F warmer on the Equator than at the South Pole.
Question 7) Felix reported that the coldest day on record for his town was five times colder than yesterday's temperature, -4 c. What was the temperature of the coldest day on record in Felix's town?
Answer: - 20C
Explanation:
i) Yesterday's temperature = - 4°C
ii) Coldest day's temperature = 5 × (-4C) = - 20C
Conclusion: the coldest day's temperature is -20°.
Question 8) the elevation of mt. Everest is 29,028 feet. The elevation of the Dead Sea is -485 feet. What is the difference in the elevation between mt. Everest and the Dead Sea?
Answer: 29,513 feet
Explanation:
i) Elevation of Mt Everest = 29,028 feet
ii) Elevation of the Dead Sea = - 485 feet
iii) Difference in the elevation = Elevation of Mt Everest - elevation of the Dead Sea
iv) Difference in the elevation = 29,028 feet - ( - 485 feet) = 29,028 feet + 485 feet = 29,513 feet.
Remember the law of the signs: ( - ) × ( - ) = +
