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
Answer:
8 pens
Step-by-step explanation:
<h2><u>Finding the number of pens bought </u></h2>
pencil costs 0.27
pen costs 0.32
6 * pencils + x pens = 4.18
6 * 0.27 + x * 0.32 = 4.18
1.62 + 0.32x = 4.18
0.32x = 4.18 - 1.62
0.32x = 2.56
x = 2.56/0.32
x = 8
<u>hence 8 pens were bought </u>
Answer:
900
Step-by-step explanation:
a heptagon has 7 sides, so we take the hexagon's sum of interior angles an and add 180 to it's getting us, 720 + 180 = 900 degrees
Let b coffee bags, c cups and lb pounds of the coffee:
b= 2.5 lb
.25lb=8 c
2.5lb * 8c/.25lb= 80 c
4(80c)= 320 c
320c - 296c = 24 cups was left.
