1.5 to 1
The scale would be 1:84
86% would be 2.58 on a 3-point scale.
That depends on the grading scale for the class.
It is the same as 2 cm = 3 m or 1 cm = 1.5 m The scale ratio would therefore be 150:1
it deals with proportion. think of a map ... it has a "scale". it would be silly to try and create a life-size map of a city, because it would cover the whole city. instead, they might use a "scale" to say that each inch on the map represents 1 mile in real life. a model airplane might have a scale of 1:30 meaning that if every measurement on the model were multiplied by 30, then it would be the size of the real thing. if you scale something by a factor of 10, you make everything 10 times bigger (or further) a scale factor of 1/10 makes everything 10 times smaller.
the scale factor would be two thirds to make an object 66.66666 re-ocurring to reduce and object by 33 percent
A scale factor is a number which scales, or multiplies, some quantity. A scale factor of two would mean to multiply whatever it is by two.
The scale would be 1:84
a scale factor of 4.5 is your answer
an ideal machine
86% would be 2.58 on a 3-point scale.
If a big triangle has a base length of 6, and a small triangle has a corresponding base length of 3, the scale factor from large to small is 2/1 (or 2). The scale factor from small to large would be 1/2.
the answer would be 10 0n apex
A scale factor in a number that changes the size of a shape by that scale examples: 1: if you have a square that is 1cm by 1cm and you increaseit by a scale factor of 3 the square would then be 3cm by 3cm 2: if you had a 2cm by 2 cm square and increase by a scale factor of 0.5 you'd get a 1cm by 1 cm square
No a scale factor of 1 is not a dilation because, in a dilation it must remain the same shape, which it would, but the size must either enlarge or shrink.
designing a scale model
No. That would be the same as having a perpetual motion machine which is impossible.
