<span>When solving a question like this, with two quantities and their different units (centimetres and millimetres in this case) you can begin by converting the values to the same units. this makes the calculations easier.
15 centimeters to millimeters = 15 x 100 ( because 1 cm has 100mm)
There are 1500 mm in 15 centimetres.</span>
Answer:
8/20 + 5/20 = 13/20
Step-by-step explanation: You would have to multiply the numerator and denominator of 2/5 by 4 to get 8/20 and multiply the numerator and denominator of 1/4 by 5 to get 5/20, equaling to 13/20.
Answer:
ln2
Step-by-step explanation:
n --> infinity
Integral of 1/N as N varies from n+1 to 2n
Integral of 1/N = ln(N)
Upper limit - lower limit
ln(2n) - ln(n + 1)
ln[2n/(n + 1)]
ln[2/(1 + 1/n)]
As n --> infinity,
1/n --> 0
ln[2/(1 + 1/n)] --> ln2
Answer:
-7
Step-by-step explanation:
To find x, substitute the values and solve.
R = 2x + 9y
It becomes:
2x + 27 = 13
Rearrange and solve
2x = -14
x = -7
Hope this helps
