Answer:

B. 51

Step-by-step explanation:

To find the answer, you need to multiply the percentage by the number of total games. To multiply the percentage, you need to transform it into a decimal. To do that, simply move the decimal in 40 two spaces to the left. Now you have 0.4. multiply 0.4*30=12. So out of 30, the team won 12 games. Do the same thing with 65% of 60 games. 0.65*60=39. So out of 60, the team won 39. Add the amount of games won total to get 51. Remember the technique in bold! Hope this Helps!

Question 35 I need help with .
iogann1982 [59]
Ok in 2001 the Barnes had 45,000, and 12% was dedicated to savings.

in 2002 their income went up by 10%, 10% of what? well, 10% of 45000, how much is that? well, 10% of anything is just (10/100) * anything

so 10% of 45000 is (10/100) * 45000 or just 4500, you simply chop off a zero

so, it went from 45000 to 45000 + 4500 or 49500

now, they do their budget the same, savings is 12% in 2002, just like in 2001, alrite, how much is 12% of 49500? well, 12% of anything is just (12/100) * anything

so... I'm sure you'd know how much (12/100) * 49500 is

What is the instataneous rate of change at x=2 of the function f given by f(x)= x^2-2÷x-1​
Dima020 [189]

Answer:

4.5

Step-by-step explanation:

To find the instantaneous rate of chance, take the derivative:

f(x) =  {x}^{2}  -  \frac{2}{x}  - 1 \\  \frac{d}{dx} f(x) = 2x +  \frac{2}{ {x}^{2} }

Remember to use power rule:

\frac{d}{dx}  {x}^{a}  = a {x}^{a - 1}

To differentiate -2/x, think of it as:

- 2 {x}^{ - 1}

Then, substitute 2 for x:

2(2) +  \frac{2}{ {2}^{2} }  \\ 4 +  \frac{2}{4}  = 4.5
