Answer:
Scale factor: 4:1
Ratio of perimeter: 4:1
Step-by-step explanation:
So basically, there is difference between the ratio of areas and the scale factor.
The area of a shape is equal to the scale factor squared.
We know that the ratio of the 2 areas is 16:1
So, the scale factor must be: ![\sqrt[2]{16}: \sqrt[2]{1}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B16%7D%3A%20%5Csqrt%5B2%5D%7B1%7D)
,
Which is basically 4:1
Because the ratio of the scale factor is also equal to the ratio of the perimeter, the ratio of perimeters is also 4:1

Answer:
what?////
Step-by-step explanation:
Answer:
b=4, h=5
Step-by-step explanation:b(b+1) divided by 2 is 10, so b(b+1)=20 so b^2 + b =20 so b^2 +b -20=0 which equals (b+5)(b-4), giving us solutions -5 and 4. However, -5 is invalid bc it is negative, so base must be 4 making height 5
Combining the inequality expression will give 0≤x<1.
<h3 /><h3>Sets and inteerval notation.</h3>
From the given information, we are to express the statement the set of all numbers greater than or equal to 0 and less than 1 in interval notation.
Let the unknown values b represented as "x"
The statement "the set of all numbers greater than or equal to 0 and less than 1" can be written as x≥ 0 and x < 1.
Combining the inequality expression will give 0≤x<1.
