What is the least number that has 4 odd factors that are all the same

Answers

factors can't be one the factors have to be Odd and the same I would say 3×3×3×3 would be equal to 9×9 = 81 the number 81 has four of factors that are all the same can't be one because one does not count as a factor a prime number has two factors one and itself every number has a factor of one and itself.

Micah construct a rectangular prism with a volume of 360 cubic units the height of his prism is 10 units Micah claims that the base of the prism must be a square draw a base that shows his claim is incorrect

Answers

Given:
rectangular prism
volume of 360 cubic units
height is 10 units

Volume = length * width * height
360 cubic units = lw * 10 units
360 / 10 = lw
36 = lw

The only measure of the sides of a square base is 6 units. 6 is the square root of 36.

To prove that the base of the prism is not a square, its measure should be

length = 9 ; 18 ; 12
width = 4 ;   2 ; 3

V =   9 x 4 x 10 = 360
V = 18 x 2 x 10 = 360
V = 12 x 3 x 10 = 360

ΔRST is dilated about the origin, O, to create ΔR'S'T'. Point R is located at (3, 9), and point R' is located at (1.2, 3.6). Which scale factor was used to perform the dilation?

Answers

Answer
scale factor=0.4

Explanation
The scale factor for any transformation is the ration of the image distance to the object distance.
That is the ratio of distance from the origin to the image to the distance from the origin to the object.
In the case above, OR’is the image distance and OR is the object distance.
OR’ = √(〖1.2〗^2+〖3.6〗^2 )=√14.4=3.794733192
OR = √(3^2+9^2 )=√90=9.486832981

The scale factor = 3.794733192/9.486832981
=0.4

Answer: 0.4

Step-by-step explanation:

We know that the a scale factor for dilation about the origin, O is the ratio of the coordinates of the image to the coordinates of the pre-image.

Given : ΔRST is dilated about the origin, O, to create ΔR'S'T'. Point R is located at (3, 9), and point R' is located at (1.2, 3.6).

Then , the scale factor for dilation is given by :-

$k=\frac{\text{x-coordinate of R'}}{\text{x-coordinate of R}}\n\n=(1.2)/(3)=0.4$

Therefore , the scale factor was used to perform the dilation= 0.4.
