The temperature of a substance in an experiment changes by -7.5°F from 8 a. m. to 2 p. m. At 5 p. m., the temperature is 43.5°F. It is 1/3 of what the temperature was at 2 p. m. What was the temperature at 8 a. m. of the substance?

ok

Step-by-step explanation:

138* F

Step-by-step explanation:

If 43.5 is 1/3 of what it was at 2 p.m. then we need to multiply the equation by three where we get 130.5. Since it changed by -7.5 we have to add 7.5 to get our final answer of 138 degrees at 8 P.M.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
