In the given question, it is already disclosed that the typing speed of Finke has increased from 40 words per minute to 45 words per minute. Now we have to find the percentage increase in the speed of typing.
For this purpose we have to find the solution in the method described below.
Number of increase in words typed per minute = 45 -40
= 5
Then Percentage increase in the speed of typing by Finke = (5/40) * 100
= (1/8) * 100
= 25/2
= 12.5
So the percentage increase in the typing speed of Finke is 12.5%. I hope this has answered your question and the description used to solve this problem is understandable.
Answer:
d
Step-by-step explanation:
f(x)-g(x)=2x²+4x-6-[2x²+2x+8]=2x²+4x-6-2x²-2x-8=2x-14
Remember that A squared plus B squared equals C squared.
Since sides F_D and D_E are both 3, the answer cannot be 4.2 or 2.4.
SO basically you just add 3 + 3 = (The side F_E, which you can get by putting numbers in the formula), you should get your answer.
3² + 3² = Line EF²
9 + 9 = Line EF²
18 = Line EF²
√18
You get the idea. Hope this helps!
For the first question, use slip and slide or the box method to get (x-2)(2x-3)
Do the same for the second question to get (3x-4)(x+1)
Answer:
500.
Step-by-step explanation:
The last digit must end with 0, 2, 4, 6, 8 for the Pin code to be even.
The middle 2 digits may be any numbers.
So if the last number is 0 Then there are 10*10 = 100 possible PIN codes.
So as there are 5 possible last digits , the total possible sets of digits
= 5 * 100
= 500.
