Work out 3/5 of 900

Answers

Answer:

540

Step-by-step explanation:

1. We assume, that the number 900 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 900 is 100%, so we can write it down as 900=100%.

4. We know, that x is 3.5% of the output value, so we can write it down as x=3.5%.

5. Now we have two simple equations:

1) 900=100%

2) x=3.5%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

900/x=100%/3.5%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 3.5% of 900

900/x=100/3.5

(900/x)*x=(100/3.5)*x - we multiply both sides of the equation by x

900=28.571428571429*x - we divide both sides of the equation by (28.571428571429) to get x

900/28.571428571429=x

31.5=x

x=31.5

now we have:

3.5% of 900=31.5

Given the definitions of f (x) and g(x) below, find the value of (gof)(-8).
f(x) = -x + 8
g(x) = x2 – 3x+2

Answers

Answer:

(gof)(-8) = 210

Step-by-step explanation:

(gof) = (-x + 8)² - 3(-x + 8) = 2

= x² - 16x + 64 + 3x - 24 + 2

= x² - 13x + 42

(gof)(-8) = (-8)² - 13(-8) + 42

= 64 + 104 + 42

= 210
