What properties of dilations and rigid transformations define similarity?

1 answer:

8 0

Two figures are similar if one can be mapped onto the other by rigid rotation, reflection, and translation. Two figures are similar if one can be mapped onto the other by rotation, reflection, translation, or dilation/rescaling. That is, they're similar if one is congruent to a rescaling of the other.

How to change 45% into a fraction How to change 120% into a fraction

Eddi Din [679]

Answer: 3/25 and 9/20

Step-by-step explanation:

We take the number and covert it into a fraction

A 2 digit Numerator = a 3 digit denominator

A 3 digit Numerator = a 4 digit denominator

And so on...

Then We can reduce,

45/100 = 9/20

120/1000 = 3/25

Hope this helped!

Because Charles David Keeling and his new colleagues began measuring CO2 in 1958, we now have an excellent record of how CO2 con

Alecsey [184]

Answer:

1. 516 ppm; 2. 561 ppm

Step-by-step explanation:

1. CO₂ increase at old rate

Time = 2100 - 2010 = 90 years

Increase in CO₂ = 90 yr × (1.4 ppm/1 yr) = 126 ppm

CO₂ in 2010 = 390 + 126 = 516 ppm

At the old rate, the CO₂ concentration in 2100 will be 516 ppm.

2. CO₂ increase at new rate

Time = 2100 - 2010 = 90 years

Increase in CO₂ = 90 yr × (1.9 ppm/1 yr) = 171 ppm

CO₂ in 2010 = 390 + 171 = 561 ppm

At the new rate, the CO₂ concentration in 2100 will be 561 ppm.
