Mr. Atlas, the weatherman, reports that the temperature at 6 a. M. Was 44.65 degrees and the temperature at 10 a. M. Is 52.14 degrees. Which is the best estimate of the number of degrees that the temperature has risen? 7 7.49 8 8.49

7

Step-by-step explanation:

First and foremost, we should note that when we estimate 52.14 degrees to the nearest whole number would be 52 degrees.

Also, when we estimate 44.65 degrees to the nearest whole number will be 45. This is because the number in it's tenth place is above 4 which means we'll add 1 to 44 making 45.

Then the best estimate of the number of degrees that the temperature has risen will be the difference between 52 and 45 which is:

= 52 - 45

= 7

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
