What number is 80% of 60?

80% of 60=48

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 60 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 60 is 100%, so we can write it down as 60=100%.

4. We know, that x is 80% of the output value, so we can write it down as x=80%.

5. Now we have two simple equations:

1) 60=100%

2) x=80%

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:

60/x=100%/80%

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 80% of 60

60/x=100/80

(60/x)*x=(100/80)*x       - we multiply both sides of the equation by x

60=1.25*x       - we divide both sides of the equation by (1.25) to get x

60/1.25=x

48=x

x=48

now we have:

80% of 60=48

the correct functions are

h(x) = 3x + 2  

g(x) = 2^x

step-by-step explanation:

i proceed to calculate the different values ​​of k (x)

case 1)  k(x) = g(x) ∘ h(x)

g(x) ∘ h(x)=g(h(x))

k(x) = [2]^[3x + > is the option  4. k(x) = 2^(3x + 2 )

case 2)  k(x) = g(x) + h(x)

k(x) = [2^x]+[3x + 2]=2^x+3x+> is the option  1.) k(x) = 2^x + 3x + 2

case 3)k(x) = h(x) ÷ g(x)

k(x) =  [3x + 2]/[2^x]=3x/(2^x)+2/(2^x)=3x*(2^-x)+2^(1-x)

is the option  3.)   k(x) = (3x)2^(-x) + 2^(-x + 1 )

case 4)k(x) = g(x) - h(x)

k(x) =  [2^x]-[3x + 2]=2^x-3x-> is the option  2.) k(x) = 2^x - 3x - 2 

case 5)  k(x) = g(x) × h(x)

k(x) = [2^x]*[3x + > is the option  5.) k(x) = 2^x(3x + 2)

case 6)k(x) = h(x) ∘ g(x)

h(x) ∘ g(x)=h(g(x))

k(x)=3*[2^x]+> is the option  6. k(x) = 3(2^x) +2
