Answer:
Weight of full steel bead tire=1.76 pounds
weight of lighter wheel=1.54 pounds.
Step-by-step explanation:
it is given that:
The weight of a full steel bead tire is approximately 800 grams.
lighter wheel weighs only 700 grams.
Now we are given conversion that:
There are 453.592 grams in one pound.
Hence, 1 gram=1/453.592 pounds.
Hence, weight of a full steel bead tire is:
Also weight of lighter wheel in pounds is:

Answer:
<h3>i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰ = 0</h3>Step-by-step explanation:
Consider the sum S = i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰
S = i¹ + i² + i³ + . . . + i⁹⁹ + i¹⁰⁰
S = a₁ + a₂ + a₃ +. . . + a₉₉ + a₁₀₀
then, S is the sum of 100 consecutive terms of a geometric sequence (an)
where the first term a1 = i¹ = i and the common ratio = i
FORMULA:______________________
_______________________________
then
or i¹⁰⁰ = (i⁴)²⁵ = 1²⁵ = 1 (we know that i⁴ = 1)
Hence
S = 0
Answer:
where the elevation, h, is in feet and time, t, is in minutes.
Step-by-step explanation:
At the time, min, the elevation,
feet and
at the time min, the elevation,
feet.
As they are hiking a steady incline, so the change in the elevation with respect to time will be constant.
So, there will be a linear relationship between the elevation and the time.
Let be the elevation at any time instant
, so the linear relation among these quantities is
where is the rate of change of elevation with respect to time and
is constant.
The change in the elevation, feet.
and the change in time, min.
So, change in the elevation in unit time,
feet/min.
Now, from equation (i)
As the elevation, at time
, so
Hence, the required equation is
where the elevation, , is in feet and time,
, is in minutes.
