The correct option is B.
Pan balance is one of the instruments that are used to measure weights of objects. The instrument is designed in such a way that, it has two pans and a standard weight can be added to one of the pan to determine the weight of the object in the other pan. In the question given above, the pan balance is to be used to measure the weight of a large rock. Salt is the right object to be used on the second pan because it can be packaged in standard weights and it is very light in weight. So, it will be very sensitive to the weight of the rock that is been added on the other pan.
Answer:
no ... the pin will not fit the reamed hole
Step-by-step explanation:
The decimal equivalent of 7/32 is 0.21875. This is larger than the reamed
hole: 0.215
and so the answer is no ... the pin will not fit the reamed hole.
The next step in his construction would have to be constructing the line between point M and point G. This is now your tangent line to the circle O. Additionally, you can also construct another tangent line that also passes through point M!
The goal is to find the area of a pentagon with side length 8.
We can find the area of a pentagon very easily by splitting it up into 10 congruent right triangles with the apothem as the height. The base of one of these triangles would be 4. The base angle would be 54 degrees, because it's half of the angle of a regular pentagon.
Using trig we find that the height of this triangle/apothem of the pentagon is equal to 4tan(54 degrees), which is about 5.506.
The area of a triangle is bh/2, so...4*5.506/2 = 11.011 in².
Times 10 triangles is 110.11 in².
I wish I could say it to you but I don't know how to plan it
