What is Number system?A number system is defined as a system of writing to express numbers.
We need to find the greatest common factor of 27 and 33.
GCF of twenty seven and seventy three.
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share.
The factors of 27 are 1, 3, 9 and 27.
One , three , nine and twenty seven because 27 is divisible by the numbers.
The factors of 33 are 1, 3, 11 and 33.
One, three, eleven and thirty three because 33 is divisible by these numbers.
The highest common factor 27 and 33 is 3
Hence, the greatest common factor of 27 and 33 is 3.

Fluffy the bunny ate 1 2 of a carrot in the morning, and she ate some more at night. By the end of the day, she still had 1 3 of the carrot left to eat. How much of the carrot did Fluffy the bunny eat at night?
Answers
Answer:
1/6
Step-by-step explanation:
Fluffy ate 1/2 carrot in the morning
She ate some more at night
At the end of the day she still had 1/3 of the carrot left
Therefore the amount of carrot fluffy are at night can be calculated as follows
x= 1-1/3-1/2
×= 1/6
Hence fluffy ate 1/6 of the carrot at night

Answer:
y = -4.5x - 22
Step-by-step explanation:
The standard form of finding the equation of a line is expressed as y = mx+c
m is the slope
c is the y intercept
Get the slope:
m = y2-y1/x2-x1
Given the coordinates (-6,5) and (-4,-4)
m = -4-5/-4+6
m = -9/2
m = -4.5
Get the y-intercept
Substitute (-4,-4) and m = -4.5 into y = mx+c
-4 = -4.5(-4) + c
-4 = 18 + c
c = -4-18
c = -22
Get the required equation:
Recall that: y = mx+c
y = -4.5x - 22
Hence the required equation is y = -4.5x - 22

Pentagon GPEST is shown on the coordinate grid. Pentagon Pentagon GPEST is dilated with the origin as the center of dilation using the rule (x,y)→(0.2x,0.2y) to create pentagon G'P'E'S'T'.
Which statement is true?
Pentagon G'P'E'S'T' is larger than pentagon pentagon GPEST because the scale factor is greater than 1.
Pentagon G'P'E'S'T' is larger than pentagon pentagon GPEST because the scale factor is less than 1.
Pentagon G'P'E'S'T' is smaller than pentagon pentagon GPEST because the scale factor is greater than 1.
Pentagon G'P'E'S'T' is smaller than pentagon pentagon GPEST because the scale factor is less than 1.

Step-by-step explanation:
Sorry im late homie
Option (4). Pentagon G'P'E'S'T' will be smaller than pentagon GPEST because the scale factor is less than 1.
Transformation of a figure by dilation: If a figure with the given vertex (x, y) is dilated with a scale factor
'k', image point will follow the rule,
(x, y) → (kx, ky)
If k > 1, image will be larger than preimage.If k < 1, image will be smaller than preimage.
Rule for the dilation given in the question,
(x, y) → (0.2x, 0.2y)
Here, k = 0.2 which is less than 1.
Therefore, pentagon G'P'E'S'T' will be smaller than pentagon GPEST.
Option (4) will be the correct option.

A. 8
B. 9
C. 10
Answers
Answer:
M=10
N=5
Q=2
Step-by-step explanation:
if you look at the equation it says
M+M+M=30
Since there's 3 M's you can combine it and make it into 3M=30.
you could then divide 30 by 3 in order to get M by itself and you would get M=10.

If ΔJKL~ΔMKN, find the value of x.
Answers
Answer:
x = 14
Step-by-step explanation:
Since the triangles are similar, then the ratios of corresponding sides are equal, that is
[tex]\frac{KL}{KN}[/tex] = [tex]\frac{JL}{MN}[/tex] , substitute values
[tex]\frac{32}{12}[/tex] = [tex]\frac{3x-2}{x+1}[/tex] ( cross- multiply )
12(3x - 2) = 32(x + 1) ← distribute parenthesis on both sides
36x - 24 = 32x + 32 ( subtract 32x from both sides )
4x - 24 = 32 ( add 24 to both sides )
4x = 56 ( divide both sides by 4 )
x = 14
