1512 I believe! :) I would double all the dimensions first, then multiply them all together.
In this situation you would have to use ratios to figure it out.
AD over EH or 24/16 that would be equal to 1.5
This would show that BC over GF is also equal to 1.5.
6/4 is equal to 1.5.
Side length BC is 6
<span>A machine needs 2 of its gears replaced. You find 2 gears, one manufactured 5 years ago and the other manufactured 10 years ago. The specifications sheet says that the chance of failure is 5% after 5 years and increases to 8% after 10 years. If the gears on the machine are in no way linked to each other, what are the chances that both will fail? Answer in % form.
-----------------------------
P(both fail) = 0.05*0.08 = 0.004 = 0.4%</span>

Step-by-step explanation:
Answer:
Option B is correct
The average rate of change of d(t) between 2 second and 4 second is; 90 ft/s
and it represents the average speed of the object between 2 seconds and 4 seconds.
Step-by-step explanation:
Average rate of change of function is defined as the ratio of the difference in the function f(x) as it changes from a to b to the difference between a and b. Then, the average rate of change is denoted as A(x).
As per the given statement, the distance d(t) is in feet and t is the time in second.
To find the average rate of change of d(t) between 2 seconds and 4 seconds.
From the table we have;
at t = 2 , d(2) = 60
and
at t =4 , d(4) = 240.
Then, by the definition of average rate of change ;
=
Simplify:
therefore, the average rate of change of d(t) between 2 second and 4 second is; 90 ft/s and it represents the average speed of the object between 2 seconds and 4 seconds.
Answer:
Step-by-step explanation:
- Total distance = 2 km
- Boundary = one round = 400 m
<u>Number of rounds:</u>
- 2 km / 400 m=
- 2000 m/ 400 m =
- 5 rounds
