Why is the equator region the hottest part of Earth’s surface?

The equator region has the widest diameter.

The sun shines directly on the equator region.

The rays of the sun hit the equator region at an angle.

The equator region is closest to the sun.

Answers

Answer 1

Answer:  The sun shines directly on the equator region.

Step-by-step explanation: Ultimately, the temperature in an area depends on the amount of the Sun's energy reaching the surface in that area. The amount of solar energy in a given area is greater at the equator than in an equal area at the poles, which is why the equator temperature is warmer than the polar temperatures. Therefore it is B

The answer will be 8 bags of popcorn and the total for the right side would be $52.50.

In order to do this, you need to find the unit rate. In order to find the unit rate, divide 11.25 and 3. The answer should be 3.75. Using this number, divide 30 by 3.75 to get 8. 8 will be the number of popcorn bags sold. Then all you have to do is multiple 14 by 3.75 to get $52.50.

Use the graph representing bacteria decay to estimate the domain of the function and solve for the average rate of change across the domain.


0 ≤ y ≤ 80, −0.6875

0 ≤ y ≤ 80, −1.45

0 ≤ x ≤ 55, −1.45

0 ≤ x ≤ 55, −0.6875

Answers

Answer: the answer is C
Hope It Helps

The domain of the given function is [0,55] and the average rate of change is -1.45 so option (C) is correct.

What is the range and domain of a function?

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

The domain is for the independent variable while the range is for the dependent variable.

The domain of a function is the set of input values that the function defines.

The function goes from x = 0 to x = 55 thus  0 ≤ x ≤ 55 will be the domain.

The average slope for (0,80) and (55,0)

⇒ (0 - 80)/(55 - 0) = -1.45

Hence "The domain of the given function is [0,55] and the average rate of change is -1.45".

Step-by-step explanation:

Part A

Divide 39.00 by 1.95 and you should get your answer

Part B

take the answer you got from part a and multiply it by the number of pencils that are in the box

Part C

take 48.00 and divide it by 4.80 and you should get your answer

Part D

take your answer from Part C and multiply it by how many card are in a box and you should get your answer

Part E

divide the amount of pencils by three and it gives you 80 and for the cards do the same but take the amount of cards and divide it by 25 and it gives you 80 so the amount is 80 bags.
