Answer:
21% of 456 = 0.21 x 400 + 0.21 x 50 + 0.21 x 6 = 95.76
Step-by-step explanation:
V = 1/3Bh
B = 1/2(b1 + b2)t
V = 1/3[1/2(b1 + b2)t] * h
h = 24
b1 = 13
b2 = 29
t = ?
V = 2856
Substitute:
2856 = 1/3[1/2(13 + 29)t](24)
2856 = 1/6(42)(24)t
2856 = 7(24)t
2856 = 168t
t = 2856/168 = 17 in height of the trapeziod
Answer:
The linear equation for Shana's elevation is
.
Step-by-step explanation:
According to the statement, we find that Shana is climbing at constant rate in time and height as a function of time can be represented by linear function:
(Eq. 1)
Where:
- Initial height above sea level, measured in feet.
- Elevation above sea level, measured in feet.
- Climbing rate, measured in feet per minute.
- Time, measured in minutes.
If we know that
,
and
. the initial height above sea level is:



The linear equation for Shana's elevation is
.
