The scale factor is between 0 and 1. The dilation is a reduction.Point O is the center of dilation.What is Scale?The ratio between a distance on a map and its actual distance on the ground is known as the map's scale. Since scale must vary throughout a map due to the curvature of the Earth's surface, this straightforward idea is made more difficult. This change makes the idea of size significant in two different ways.
Given, Triangle A B C is reduced to triangle A prime B prime C prime. Triangle A prime B prime C prime is closer to point O. For that we have to imagine a Dilation point.
So, Let "O" origin point is the dilation center for the given Triangles.
Since triangle A'B'C' is closer to the origin point thus the Scale factor will be less than 1 and Dilation will be reduced
Thus, option A is correct.
Since triangle A'B'C' is closer to the origin point thus the Scale factor will be less than 1
Thus, option B is correct.
Since it is a dilation thus A is not the image of A'
since the scale factor is not mentioned thus we can say that if OB = BB'
Therefore, options A, B, and D are correct.

How many bacteria will there be in 4.5 hours? In 5 hours?
Answer:
4.5 hours in minutes = 270
Every 45 minutes, bacteria triples
You start with 50
Divide 270 (total time) by 45 (every time bacteria triples)
270/45 = 6
36,450 bacteria

HELP What's greater -1 17/20 or -1 8/10
Use < or >
Answer:
The answer is -1 17/20 < -1 8/10.
Step-by-step explanation:
If you would calculate it to decimal, you should get:
a) -1 17/20= -1.85 or can be -37/20
b) -1 8/10= -1.8 or can be -9/5 or -1 4/5
As you can see, -1 8/10 has a larger decimal value so the answer would be -1 17/20 < -1 8/10.

Answer:
x=20
Step-by-step explanation:
The line equal 180 degrees, and we already know one angle so, 180-80=100. The two missing angles are equal to 100 so add them up and divide by 5.
2x + 3x =100
5x=100
x=20

Answer:
We can use the SAS. (B)
Step-by-step explanation:
- The triangles have a side in common (XZ): SIDE (S)
- Also, the triangles XWZ and XYZ have a right angle in the vertex Z: ANGLE (A)
- Lastly, the sides WZ and ZY have the same lenght, since they're marked with the same signal: SIDE (S)
So, the postulate SAS (side-angle-side) can be directly used to determine that XWZ and XYZ are congruents. Hence, the answer is the alternative B.

Answer:
Step-by-step explanation:
2x - 5y + 3z = 27
4x + 3y - 7z=-37
x - 2y + 5z = 30
I need help solving this with cramers rule
Step-by-step explanation: answer {x,y,z} = {1,-2,5}
/ Solve equation [3] for the variable x
[3] x = 2y - 5z + 30
// Plug this in for variable x in equation [1]
[1] 2•(2y-5z+30) - 5y + 3z = 27
[1] - y - 7z = -33
// Plug this in for variable x in equation [2]
[2] 4•(2y-5z+30) + 3y - 7z = -37
[2] 11y - 27z = -157
// Solve equation [1] for the variable y
[1] y = -7z + 33
// Plug this in for variable y in equation [2]
[2] 11•(-7z+33) - 27z = -157
[2] - 104z = -520
// Solve equation [2] for the variable z
[2] 104z = 520
[2] z = 5
// By now we know this much :
x = 2y-5z+30
y = -7z+33
z = 5
// Use the z value to solve for y
y = -7(5)+33 = -2
// Use the y and z values to solve for x
x = 2(-2)-5(5)+30 = 1
which expression is not equal to 30
(9 x 10) + (4+1) + 12
2+(30-8÷4)
(120÷20)×(2+3)

Amy bought x pencils at RM 0.60 each and y erasers at RM0.40 each. She sells the pencil at
RM0.85 each and the eraser at RM0.60 each. Write an algebraic expression for Amy's total profit,
in sen.
Answer:
Profit = 0.25x + 0.20y
Step-by-step explanation:
cost price of 1 pencil = RM 0.60
So, C. P. of x pencils = 0.60x
Similarly,
C. P. of y erasers = 0.40y
Total C. P. = 0.60x + 0.40y
Selling Price of x pencils = 0.85x
S. P. of y erasers = 0.60y
Total S. P. = 0.85x + 0.60y
Profit = Total S. P. - Total C. P.
= (0. 85x + 0.60y) - (0.60x + 0.40y)
= 0. 85x + 0.60y - 0.60x - 0.40y
= 0.85x - 0.60x + 0.60y - 0.40y
Profit = 0.25x + 0.20y

sandy and Selena both sell bracelets that they make. Sandy spent $25 on her materials to start and sells her bracelets for $10. Selena spent $73 on her materials and sells her bracelets for $26
After how many bracelets will the money taken in (y) and the number of bracelets sold (x) be the same for the girls?
Answer:
After 3 bracelets , the money taken in and the number of bracelets sold will be the same for the girls
Step-by-step explanation:
Let the number of bracelets that makes the amount of profit made be equal be x
For Sandy, her gain will be 10x - 25
For Selena, her gain will be 26x - 73
So equating both, we can find x
10x - 25 = 26x - 73
26x-10x = 73-25
16x = 48
x = 48/16
x = 3
To get the amount, we can make a substitution for x
we have;
10(3) - 25 = 30-25 = $5

Lakita wants to go to trade school and study electronics for a two-year program. Her tuition and books will cost about $5,500 per year. She will also spend about $100 a month commuting from her parents’ house to school. How much will her education cost her in total?
Answer:
$13,400Step-by-step explanation:
Step one:
let us first compute the tuition and books for the two years
we are told that the tuition is $5,500 per year
For the two years,the tuition will be 5,500*2= $11,000
Step two:
we need to calculate the cost of transportation for the two years also
in two years there are 24 months
if Lakita will spend $100 per months
then in 24 months Lakita will spend= 24*100= $2400
Hence her education cost her in total is
=$11,000+$2400
=$13,400
