What is a scale problem?
A situation in financial management where the internal rate of return (IRR) method may lead to an investor choosing a higher IRR that may give him a lower return than a project with a smaller IRR may give him a higher return.
What is the balance scale problem?
task, the balance scale. In balance scale experiments, the child is asked to predict the outcome of placing certain numbers of equal weights at various distances to the left or fight of a fulcrum. Both stage progressions and information salience effects have been found with children on this task.
What is the scale factor of a drawing if the scale is 1 inch 6 feet?
1 to 72
The scale “1 inch to 6 feet” is equivalent to the scale “1 to 72,” because there are 72 inches in 6 feet. The scale “1 to 100” would make a scale drawing that is smaller than the scale “1 to 72,” because each inch on the new drawing would represent more actual length.
What are the types of scale drawing?
Types of Scales in Engineering Drawing
- Plain Scale.
- Diagonal Scales.
- Comparative Scale.
- Vernier Scale.
- Scale of Chords 1. Plain Scale Plain scale is cleanly a line which is separated into a proper number of equal parts, first of which is further sub-divided into small parts.
How do you find scale factor?
To find the scale factor, locate two corresponding sides, one on each figure. Write the ratio of one length to the other to find the scale factor from one figure to the other. In this example, the scale factor from the blue figure to the red figure is 1.6 : 3.2, or 1 : 2.
How many triangles will balance the system?
Ans is 6 yellow triangles.
How do I find the lightest coin?
To find the lighter one, we can compare any two coins, leaving the third out. If the two coins weigh the same, then the lighter coin must be one of those not on the balance. Otherwise, it is the one indicated as lighter by the balance. Now, imagine the nine coins in three stacks of three coins each.
How do you scale proportions?
To find the scale factor of the drawing to the actual fence, first write a ratio that compares of the two quantities. Next, compare the quantities using the same units. Convert feet to inches by multiplying the ratio by the conversion rate of 1 ft = 12 in. Then, simplify the fraction.
What is full size scale?
1 : identical to an original in proportion and size full-scale drawing. 2a : involving full use of available resources a full-scale biography full-scale war.
What is the importance of scale drawing?
An accurate scale drawing lets you see exactly how each component will fit and how much space you’ll have, both empty and filled. Whether you are addressing space concerns, adding or rearranging components or even working on multiple designs, scale will always play a key role in the planning of your project.
What is the scale factor of 2?
Linear scale factor For example, a scale factor of 2 means that the new shape is twice the size of the original. A scale factor of 3 means that the new shape is three times the size of the original. You can get the ‘big’ and ‘small’ from the corresponding sides on the figures.
What is the difference between scale and scale factor?
A scale model is a proportional model of a three-dimensional object. Its dimensions are related to the dimensions of the actual object by a ratio called the scale factor. A scale is the ratio between two sets of measurements. Scales can use the same units or different units.
How many squares would balance the third scale?
From the first scale, we determined that 3 triangles is equal to 2 squares, so adding 2 squares to the right side of the third scale would balance it.
How many yellow triangles are there?
Your comment on this answer: Ans is 6 yellow triangles.
How can you tell a fake coin?
Use a scale that is accurate to within 0.01 grams to measure the weight of the coin. Compare your results to that of the genuine coin. If they are significantly off, you may have a counterfeit coin. Use an extremely strong magnet to see if the coin is attracted to it.
