70 miles x
————— = ———-
1 hour 14 hours
Cross multiply.
70 • 14 = x
980 = x
Alejandra drove 980 miles.
The statement that can be put in the blank to make the statement true would be 30 X 10^5 or you can also write this expression as 3.0x10^6.
I believe the answer is 21
Answer:
I think it's the second one.
Step-by-step explanation:
Hope dis helps :D
<span>We need to calculate noon sun angle. Noon sun angle is an angle at which sun-rays fall at noon on a given date.
</span>On September 22, the sun’s rays form a 90° angle at noon at the equator.
Formula for calculating noon sun angle is:
Noon_sun_angle = 90° - Zenith angle
We have complementary angles so we need to substract zenith angle from 90°.
The zenith angle is the distance between subsolar point (point where sun is at 90°) and the latitude of an observer. In our case this angle will have same value as latitude because subsolar point is at equator 0°. If our latitude and subsolar point are at same hemisphere we substract values. Otherwise we add values.
New Orleans, USA
Latitude = 30°
Noon_sun_angle = 90° - 30° = 60°
Helsinki, Finland
Latitude = 60°
Noon_sun_angle = 90° - 60° = 30°
