Answer:
120 miles
Step-by-step explanation:
Step up a portion. Here, 1 cm is to 1.5 cm as 80 mi is to x mi
1/1.5 = 80/x
Now solve for x by cross multiplying
x = 120
Answer: -7
Step-by-step explanation:
w = -1, x = -2, y = -3, z = -4
z/x + -8y + 2w - wxyz
(-4)/(-2) + (-8)(-2) + (2)(-1) - (-1)(-2)(-3)(-4)
2+ 16 + (-1) - (24)
18-1-24
-7
Answer:
There fore the probability that the counters are blue is ![\frac{15}{39}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B39%7D)
Step-by-step explanation:
There are a total of 14 red counters and 39 in total. The total of red counter can be represented as a fraction of
. To find out the number of blue counter we subtract 14 from 39. This gives us 25. This is
. Therefore the probability that the counters are blue is
We are asked in the problem to determine the limit of integral of x dx as x approaches to 2. In this case, the first step to do is to integrate first the function. The integral of x dx by the power rule is equal to x^(n+1)/n+1. In this case, since n is equal to 1 from the given, then integral of x dx is equal to x^2/2. To evaluate the limit of x as x approaches to 2, we just have to substitute x by 2, that is
2^2 / 2 equal to 2. Hence the answer to this problem is equal to 2.
Your answer should be 126.4 (rounded)
