Answer:
h(t) = -5t + 500
Step-by-step explanation:
At time zero, the elevator is at 500 ft.
At time 5 seconds, the elevator is at 475 ft.
The difference in height is -25 ft.
The elevator traveled -25 ft (25 ft down) in 5 seconds, so it travels at a speed of 5 ft per second. Since it is traveling down, its speed is -5 ft/sec.
For each second of travel, it loses 5 ft of height.
h(t) = -5t + 500
Given:
Inner cone: diameter = 12 cm ; height = 6 cm
Outer layer: diameter = 12 cm ; height = 15 cm
Volume of a cone = π r² h/3
Inner cone: V = 3.14 * (6cm)² * 6cm/3 = 3.14 * 36cm² * 2cm = 226.08 cm³
Outer layer: V = 3.14 * (6cm)² * 15cm/3 = 3.14 * 36cm² * 5cm = 565.20 cm³
Volume of Outer layer : 565.20 cm³
less: Volume of inner layer:<u> 226.08 cm³</u>
Volume of cream filling: 339.12 cm³
15 and 12 are means and 3 and 60 are extremes of the above proportion.
Explanation:
Means and Extremes of Proportion
Suppose two ratios a:b and c:d are in proportion.Then it can be expressed as
<span><span>ab</span>=<span>cd</span></span>
Here, a, d = extremes and,
b, c = means

Step-by-step explanation:
Q9. 5n + 8 = 43
5n = 43 - 8
5n = 35
n = 35/5
n = 7
Q10. y/6 - 7 = 4
y/6 = 4 + 7
y/6 = 11
y = 11×6
y = 66
Q11. 8w - 15 = 57
8w = 57 + 15
8w = 72
w = 72/8
w = 9
Q12. g/3 + 11 = 25
g/3 = 25 - 11
g/3 = 14
g = 14×3
g = 42
Q13. f/5 - 22 = -25
f/5 = -25 + 22
f/5 = -3
f = -3×5
f = -15
Q14. -4p + 19 = 11
4p = 19 - 11
4p = 8
p = 8/4
p= 2
