Step-by-step explanation:24x5+3 + 4x4x4x4 x 8x5+1 -2
Answer:
58/100
Step-by-step explanation:
50 times 2 is 100, so we multiply the other number by 2 because what you do to the bottom you do to the top.
29 times 100 is 58
your answer is 58/100
5-3=2
50/5x2+5/ 1/5
10x2=20
5/. 1/5= 25
20+25=45
Answer:
6-hours
D = C + T
Step-by-step explanation:
The following equations represent the total distance travelled by each vehicle, the truck (C) and the Train (T) where x is the amount of time travelling in hours...
C = 45x
T = 60x
Since the truck traveled 2 hours longer than the train we can add this value to the variable x in the truck's distance equation and then make both equations equal one another to calculate the number of hours before they cover the same distance...
45(x+2) = 60x ... distribute 45 evenly
45x + 90 = 60x ... subtract 45x from both sides
90 = 15x ... divide both sides by 15
6 = x
Finally, we can see that both vehicles would have traveled the same distance at the 6-hour mark. Now to calculate the total distance traveled (D) we can use the following equation...
D = C + T
Answer:
A) ![V =12500[1-\frac{17.2 \times t}{100} ]](https://tex.z-dn.net/?f=V%20%3D12500%5B1-%5Cfrac%7B17.2%20%5Ctimes%20t%7D%7B100%7D%20%5D)
B) ![V = 12500[1-\frac{19}{100} ]^{t}](https://tex.z-dn.net/?f=V%20%3D%2012500%5B1-%5Cfrac%7B19%7D%7B100%7D%20%5D%5E%7Bt%7D)
Step-by-step explanation:
In two years i.e. from 2013 to 2015 the car value decreases from $12500 to $8200.
a) If the rate of decrease is constant and it is r% per year, then
![8200 = 12500[1-\frac{r \times 2}{100}}]](https://tex.z-dn.net/?f=8200%20%3D%2012500%5B1-%5Cfrac%7Br%20%5Ctimes%202%7D%7B100%7D%7D%5D)
⇒ r = 17.2%
Therefore, the value of the car is given by , where, t is in years since 2013. (Answer)
b) If the rate of decrease is exponential and it is r%, then
![8200 = 12500[1-\frac{r}{100} ]^{2}](https://tex.z-dn.net/?f=8200%20%3D%2012500%5B1-%5Cfrac%7Br%7D%7B100%7D%20%5D%5E%7B2%7D)
⇒ r = 19%
Therefore, the value of the car is given by , where, t is in years since 2013. (Answer)
