Answer:

25.9 feet per second.

Step-by-step explanation:

For the first 14 seconds, the change in elevation was –65×14= –910 feet.

For the remaining 6.5 minutes, the change in elevation was –1,470×6.5 = –9,555 feet.

The overall change in elevation was –910+ –9,555= –10,465 feet.

The total number of seconds was

6.5×60=14+390=404 seconds. The Average change in elevation was −10,465÷404=25.9 feet per second.

I WILL MAKE YOU THE BRANLIEST

The area of a triangle is given by half the multiplication of base and height. Since you want the answer is squared centimeters, let's convert base and height in centimeters first:

$b = 4.3 m = 430 cm, \qquad h = 2.6m = 260 cm$

Now we can do the computation:

$A = \dfrac{430cm \cdot 260cm}{2} = 55900 cm^2$

Step-by-step explanation:

In Exercise B, the complement of an angle is 90° - ∠X

4. 90° - 45° = 45°

5. 90° - 20° = 70°

6. 90° - 30° = 60°

7. 90° - 55° = 35°

8. 90° - 75° = 15°

9. 90° - 80° = 10°

In Exercise C, the supplement of an angle is 180° - ∠X

10. 180° - 20° = 160°

11. 180° - 105° = 75°

12. 180° - 90° = 90°

13. 180° - 150° = 30°

14. 180° - 135° = 45°

15. 180° - 120° = 60°
