First we have to calculate the amount of interest. This can be done by using the interest formula, I = P x R x T.
= 25,000 x 0.13 x (100/365)
= 902.78
This will be deducted from the principal amount, which is 25,000.
= 24,097
Last, we plug our values in to the effective rate formula for interest:
![\frac{Interest}{Proceeds x Time of Note}](https://tex.z-dn.net/?f=%20%5Cfrac%7BInterest%7D%7BProceeds%20x%20Time%20of%20Note%7D%20)
902.78/6693.6722
= 13.487066
After rounding, we come to our final answer, which is D, 13.49%.
First part of the race
speed1, s1 = 8.75 km/h
distance1 = 5 km - x
time 1 = 0.65 h - t
Second part of the race
speed2, s2 = 6 km/h
distance2 = x
time2 = t
s2 = x/t = 6 ⇒ t = x / 6
s1 = [5 - x] / [0.65 - t] = 8.75
5 - x = 8.75 [0.65 - t]
5 -x = 8.75(0.65) - 8.75t
5 - x = 5.6875 - 8.75 (x/6)
5 - x = 5.6875 - 1.4583x
1.4583 x - x = 5.6875 - 5
0.4583 x = 0.6875
x = 0.6875 / 0.4583 = 1.5
Answer:
x=9
Step-by-step explanation:
-3x-12=-39 Add the like terms (if you add 12 to negative 12 it cancels out)
+12 +12
-3x=-27 Now divide
/-3 /-3
x=9
Answer: 18 inches
Step-by-step explanation:
We can represent the whole situation by the formula
solve by cross product
50x = 900
x = 18
