HArd MAth 4 Math geniuses!!!!?

Question

1. Is the percent increase from 50 to 100 the same as the percent decrease from 100 to 50?

2. Andrea purchased a picture frame for $14.56. This price was a 30% markup from the wholesale cost. What was the wholesale cost?

3. For altitudes up to 36,000 ft, the relationship between temperature and altitude can be described by the formula ( t= -.0035a+g), where t is the temperature in degrees Fahrenhiet, a is the altitude in ft, and g is the ground temperature in degrees Fahrenheit. Solve this formula for a.

4. A red kite is 100 ft off the ground and is rising at 8 ft per second. A blue kite is 180 ft off the ground and is at 5 ft per sec. How long will it take for the red kite to be higher than the blue kite? Round your answer to the nearest second.

5. What percent of all 2-digit numbers formed with only the digits 0,1,2,3 are even numbers. Explain

Answer 1

is this trivia?

Answer 2

LOL @ you calling is trivia and asking genuises to answer

Answer 3

1) NO. 50 x X = 100 X=2 or 200%

           100 x X = 50 X=.5 or 50%

2) X x 1.3 = $14.56 ? = $11.20

3) t = -.0035a + g

   -g                   -g

    t -g = -.0035a

   /-.0035       /-.0035

   a = (t-g)/-.0035

4) 100 + 8X>180 + 5x

    -100           -100

         8X>80+5x

        -5x            -5x

      3X> 80

      /3     /3

     X> 27 seconds

after 27 seconds the red kite will be higher than the blue kite

5) All 2 digit numbers ending in 0 and 2 are even so 1/2 of the numbers would be even so 50%
