well, every second he's 59 meters closer to Lois, so if at 15seconds he's 1215 meters, then the second before that he was 1215+59 meters closer.
how close is he at 29 seconds? since the 29second is 14 seconds away from the 15th, just hop 14 times from the 15th second, or 1215 + 14(-29)
X=1, y=4
Substitute 4x in for y in the second equation and you get 5x=5. Divide out 5 and you get x=1. Then, you can plug 1 in for x into either equation and solve for y.
Answer:
x = 
will be the expression.
Step-by-step explanation:
In this question an expression has been given which represents the relation between average cost C and number of T shirts (x) manufactured.
We have to solve this expression for the value of x (number of T-shirts) in terms of C.
C = 5x + 410x
C = 415x
x =
Therefore, x = will be expression showing the number of T-shirts in terms of average cost.
Answer:
2.161 to the nearest thousandth.
Step-by-step explanation:
x = log4 20
By the definition of a logarithm:
20 = 4^x
ln 20 = x ln 4
x = ln20 / ln 4
x = 2.161 to the nearest thousandth.
0.45*0.2= 0.09
so probability that there will be oil after the test= 0.09 %
