Answer:
subject?
Step-by-step explanation:
In this problem, the average is already given. In order to solve for the missing length of jump rope we have the following solution:
Let x = be the total length
X = 4(112)
X = 448
Therefore,
34m + 1m + 212m = 247m
448m - 247m = 201 length of the fourth jump rope
Answer:
Step-by-step explanation:
For a trapezoid, the area is:
S=(b+B)h/2, where b and B are the bases, and h is the height.
b=2
B=2+2+2=6
h=2.
S=(2+6)×2/2=8
Answer:
Rate of change in elevation = 0.6 in/year
Step-by-step explanation:
Note:
Current elevation (Missing) = 7,602 feet
Given:
Old elevation = 7,602 feet
Number of year = 7,600
Find:
Rate of change in elevation
Computation:
Change in elevation = 7,602 - 7,600
Change in elevation = 2 ft
Change in elevation = 2 x 12 = 24 inches
Rate of change in elevation = 24 / 40
Rate of change in elevation = 0.6 in/year
