16% of 150 is what number plz show work
bazaltina [42]
To get the solution, we are looking for, we need to point out what we know. 

<span>1. We assume, that the number 150 is 100% - because it's the output value of the task. </span>
<span>2. We assume, that x is the value we are looking for. </span>
<span>3. If 150 is 100%, so we can write it down as 150=100%. </span>
<span>4. We know, that x is 16% of the output value, so we can write it down as x=16%. </span>
5. Now we have two simple equations:
1) 150=100%
2) x=16%
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:
150/x=100%/16%
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 16% of 150

150/x=100/16
<span>(150/x)*x=(100/16)*x       - </span>we multiply both sides of the equation by x
<span>150=6.25*x       - </span>we divide both sides of the equation by (6.25) to get x
<span>150/6.25=x </span>
<span>24=x </span>
x=24

<span>now we have: </span>
<span>16% of 150=24</span>

PLEASE HELP ASAP! A mountain climber is at an altitude of 2.9 mi above the earth’s surface.
shutvik [7]
You can use Pythagorean theorm to solve.

a^2 + b^2 = c^2
C = 3959 + 2.9 = 3961.9

x = ???? = a
b = 3959
Plugin our data.
a^2 + b^2 = c^2
a^2 + 3959^2 = 3961.9^2
a^2 + 15673681 = 15696651.61
a^2 = 22970.61
\sqrt{a^2} = sqrt{22970.61}
a = 151.560
x = 151.560
x = 151.6

What are the solutions to the equation and check for extraneous solutions:<br><br> 16=(x-2)^2/3
GuDViN [60]

Answer:

we have  x = -62 or x = 66

Step-by-step explanation:

16=(x-2)^2/3

I would take square root first

4 =  (x - 2)^ (1/3)

or   -4  =  (x - 2)^(1/3)

.....

4^3  =  x - 2

64 = x - 2

x = 66

or  -4 ^3 = x - 2

-64 = x - 2

x = -62

we have  x = -62 or x = 66
