Jack and Jill got tired of falling down that hill with a pail of water and decided to try flying a kite instead. Jack is holding

the kite string, and Jill is standing directly under the kite. The kite string forms a 61° angle with the line of sight between Jack and Jill, who are the same height. The two BFFs are standing 12 yards apart. How long is the kite string?

Because Jill is standing directly under the kite the angle between jack Jill and the kite is 90°
so
a=12 yards
A°=61°
B°=90°
b=?
to find b we have a formula:
a devided by the sinus of A equals b devided by the sinus of B

12÷sin(61°)=b÷sin(90°)
12÷0.8=b÷1
15=b

1. Is the average change in population is the same now as it was 50 years ago? Explain your answer.
katrin [286]

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.
