Answer:
Currently temperature = 35°F
Rate of descend = 4°F
We have to reach = -1°F
Temperature to get cooled down = |-1 + 35| (The two lines mean absolute value)
=> 36°F
Hours = Total temperature to get cooled / Rate
=> 36 / 4
=> 9 hours
Equation = 4x = |1 + 35|
If my answer helped, kindly mark me as the brainliest!!
Thank You!!
Let the exterior angle be y.
We know that the exterior angle is the sum of opposite two interior angles.
Therefore, y = 3x + 90 --- (1)
Also, y and 5x - 6 are linear pair.
Therefore, y + (5x - 6) = 180
Substituting y = 3x + 90 from (1), we get,
(3x + 90) + (5x - 6) = 180
8x + 84 = 180
8x = 180 - 84 = 96
x = 12 degrees
Hence, exterior angle y = 3(12) + 90 = 126 degrees.
(7^5 * 7^3)^4 * 7^-2 / 7^-7 * 7^20
= (7^8)^4 * 7^-2 / 7^(-7 + 20)
= 7^32 * 7^-2 / 7^13
= 7^(32 - 2) / 7^13
= 7^30 / 7^13
= 7^(30 - 13)
= 7^17
The following table shows the probabilities for rolling a certain number with a two-dice roll. If you want the probabilities of rolling a set of numbers (e.g. a 4 and 7, or 5 and 6), add the probabilities from the table together. For example, if you wanted to know the probability of rolling a 4, or a 7:
3/36 + 6/36 = 9/36.
