Answer:

Step-by-step explanation:

To draw a perpendicular to line L we will use the following steps.

1). We will use the compass first. We will put the compass at the point P and draw an arc which will intersect the line L at two distinct points.

2). Now we will again draw two arcs by taking same measurement in compass

so that these arcs intersect each other.

3). Now we will joint the point of intersection formed by the arcs to the point P with the help of ruler.

In this way we get the line perpendicular to line L.

86 is 45% of what number
Alik [6]
Hello there! We are talking about 86 being part of a number, so we are looking for the whole. To find the number we are looking for, we can write and solve a proportion. Set it up like this:

86/x = 45/100

86 is 45% of a number. We know the part, so now we are looking for the whole. 45% is part of 100%, so we put that part together. Cross multiply the digits. 100 * 86 is 8,600. 45 * x is 45x. That simplifies to 8,600 = 45x. Now, divide each side by 45 to isolate the x. 45x/45 cancels out. 8,600/45 is 191.1111111 or 191 1/9 in fraction form. There. x = 191 1/9 86 is 45% or 191 1/9

Note: Or, if you have to round to the nearest whole number, the answer is 191, or if you have to round to the nearest tenth, the answer is 191.1. It all depends on if the answer needs to be rounded or exact.
