100%/x%=95/38 (100/x)*x=(95/38)*x - we multiply both sides of the equation by x 100=2.5*x - we divide both sides of the equation by (2.5) to get x 100/2.5=x 40=x x=40
To get the solution, we are looking for, we need to point out what we know.
<span>1. We assume, that the number 95 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 100% equals 95, so we can write it down as 100%=95. </span> <span>4. We know, that x% equals 38 of the output value, so we can write it down as x%=38. </span> 5. Now we have two simple equations: 1) 100%=95 2) x%=38 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: 100%/x%=95/38 6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 38 is what percent of 95
100%/x%=95/38 <span>(100/x)*x=(95/38)*x - </span>we multiply both sides of the equation by x <span>100=2.5*x - </span>we divide both sides of the equation by (2.5) to get x <span>100/2.5=x </span> <span>40=x </span> x=40
<span>now we have: </span> <span>38 is 40% of 95</span>
64 cm^2. First find the area of the triangular faces by taking a quarter of the base and multiplying it by the height and then doubling it. After you've found the area of one of these faces multiply it by 4 to find the areas of all the triangular faces. Finally add the base square which is the base times base.
