Answer: 24
Step-by-step explanation:
<u>Evaluate (y+z)2 when y=−3 and z=15.</u>
(-3 + 15)*2 = 12 * 2 = 24
There are 1760 yards in a mile
2 miles = 3520 yards
he runs 80 yards per practice (4×20)
3520÷80= 44
he needs to do the practice 44 times.
--------------
There are 128 oz in a gallon
he brought two gallons, meaning 256 oz
each cup holds 8 oz
256 ÷ 8 = 32
he can serve 32 cups.
No, the average change in population is not the same as it was 50 years ago.
Reason in Support of the Answer:
In many important ways, the demographic future of the United States and the rest of the world is substantially different from the recent past. The world's average population approximately tripled between 1950 and 2010, and the U.S. population nearly doubled.
However, it is anticipated that between 2010 and 2050, both globally and in the United States, average population growth will be substantially slower and will disproportionately favor the oldest age groups. Hence it is seen that the average change in population is never constant. It depends on the demographic trends and conditions, whether the average change in population will be larger or comparatively trivial in the future. And, similarly, it can be said that the average change in population is not the same as it was 50 years ago.
