A 1/3 scale factor is a constant of dilation that is used to change the size of a figure by a factor of 1/3. A dilation is a transformation that changes the size of a figure while preserving its shape.
In a dilation, the scale factor is multiplied by the coordinates of each point on the figure to determine the new coordinates of the dilated figure. If the scale factor is 1/3, then the coordinates of each point on the figure will be multiplied by 1/3, meaning that each point on the figure will be moved one-third as far from the origin as it was before the dilation.
The result of this is that the dilated figure will be smaller than the original figure and will have a scale factor of 1/3. It's important to note that if the scale factor is less than 1, the dilation will reduce the size of the figure and if the scale factor is greater than 1, the dilation will increase the size of the figure.

Matt's four cousins are coming to visit. There are four identical rooms that they can stay in. If any number of the cousins can stay in one room, how many different ways are there to put the cousins in the rooms
The total number of different ways there are to put the cousins in the rooms is; 15
How to use probability combinations?When we count the number of cousins staying in each room, it means that the possibilities are as follows; (4,0,0,0), (3,1,0,0), (2,2,0,0), (2,1,1,0), (1,1,1,1).
1) (4,0,0,0): This means that there is only 1 way to put all the cousins in the same room due to the fact that the rooms are identical.
2) (3,1,0,0): This means that there are 4 ways to choose which cousin will be in a different room than the others.
3) (2,2,0,0): This means that there are 3 ways to choose which of the other cousins will also stay in that room, and then the other two are automatically in the other room.
4) (2,1,1,0): This means that the number of ways to choose which cousins stay in the same room is; 4C2 = 6
5) (1,1,1,1): This means that there is only one way for all the cousins to the total number of possible arrangements is;
1 + 4 + 3 + 6 + 1 = 15each stay in a different room.
Therefore, the total number of possible arrangements is;
1 + 4 + 3 + 6 + 1 = 15

The point-slope form of the
equation of a line that passes through points (8, 4) and (0, 2) is y - 4 = ~(x - 8). What is
the slope-intercept form of the
equation for this line?
y= ~x-12
y= =x-4
y=~x+2
V= x+6
Answer: y = -x + 2
Step-by-step explanation:
Point slope form is y - y = m(x - x)
m = the slope of the line
Slope-intercept form is y = mx + b
m = the slope of the line
b = y-intercept
So because the - is in the m spot in the point-slope form, that means that is the slope of the line meaning it will also be in the m spot in slope-intercept form. The y-intercept of the line is found when x is 0. When we look at the two coordinates provided you can see that one of them shows when x is 0. We see that when x is 0, y is 2 which means that the y-intercept is 2.
So when you put the 2 in place of b, you get y = -x + 2
A recipe for fruit punch calls for 333 liters of orange juice and 222 liters of pineapple juice. Jo creates a drink by mixing 444 liters of orange juice with 333 liters of pineapple juice. Which recipe will have the stronger pineapple taste
The jo's drink have stronger pineapple taste.
Given that fruit punch calls for 333 liters of orange juice and 222 liters of pineapple juice and Jo creates a drink by mixing 444 liters of orange juice with 333 liters of pineapple juice.
In the Recipe for fruit punch calls
The Number of liters of orange juice = 333.
The Number of liters of pineapple juice = 222.
Thus, Total number of liters of juice = 222+333= 555 liters
Now, % of pineapple juice in fruit punch is
P₁=(222/555)×100
P₁=0.4×100
P₁=40%
Further, % of orange juice in fruit punch is
O₁=(333/555)×100
O₁=0.6×100
O₁=60%
In Jo's drink
The Number of liters of orange juice = 444.
The Number of liters of pineapple juice = 333.
Thus, Total number of liters of juice = 444+333= 777 liters
Now, % of pineapple juice in jo's drink is
P₂=(333/777)×100
P₂=0.43×100
P₂=43%
Further, % of orange juice in jo's drink is
O₂=(444/777)×100
O₂=0.57×100
O₂=57%
Hence, the taste of both drinks was not the same, jo's drink will have a stronger pineapple taste and jo's drink will have a lesser orange taste.

a.) 24in
b.)75.36in

1a. The radius is half of the diameter, so all you have to do is add 12 + 12 which is 24.
1b. the circumfrence of a circle is C (Circumfrence)=[tex]2\pi r[/tex] so replace radius for 12 and then do 3.14(pi) x 2 which will get you 6.28 times 6.28 by 12 and you will get 75.36.
1c. Area=[tex]\pi r^{2}[/tex] so first do the radius by the second power, or [tex]r * r[/tex], susitute r for 12 and you will get 144, times 144 by pi and you will get 452.16in

One number is 4 more than another and their sum is 60.
If x = the larger number and y = the smaller number, then which of the following is the value of the smaller number?
The larger number is 32 and the smaller number is 28 given that one number is 4 more than another and their sum is 60. This can be obtained by forming algebraic equation and finding
Calculate the value of the numbers:Given that one number is 4 more than another,
⇒x = y + 4 (equation (1))
Their sum is 60,
⇒x + y = 60
y + 4 + y = 60 (From (1))
2y + 4 = 60
2y = 56 ⇒ y = 28
x = y + 4 = 28 + 4 = 32
Hence the larger number is 32 and the smaller number is 28 given that one number is 4 more than another and their sum is 60.

When solving the following system of equations, which variable would be the easiest to solve for? 2x + y = 9 3x - 2y = 17
Answer:
In my opinion, it would be 'y', since it is already on its own (in the first equation) without any coefficients.
Answer:
x.
Step-by-step explanation:
x because if you multiply the first equation by 2 and add the result to equation 2 , the y's will cancel out.
2x + y = 9 Times 2:-
4x + 2y = 18
3x - 2y = 17 Adding:-

By the exterior angle theorem,
[tex]x+18+x+12=x+48\\\\2x+30=x+48\\\\x+30=48\\\\x=18[/tex]
Answer:
x = 18
Step-by-step explanation:
The sum of two interior angles im a triangle is equal to one exterior angle that is supplementary to the third interior angle:
x + 18 + x + 12 = x + 48 add like terms
2x + 30 = x + 48 transfer like terms to the same side of the equation

Step-by-step explanation:
there's 12 red cards and 23 black cards
total = 35 cards
probability to pick a black card = 23/35
Answer: 23/35
Step-by-step explanation:
Probability is the measure of the likelihood of an event occurring. It is measured by the number of favorable outcomes over the total number of possible outcomes.
Here, the event is a black card being drawn. Since there are 12 + 23 = 35 cards in the deck, there are 35 possible outcomes of what card is picked. Out of those 35 cards, 23 are black, making 23 of the 35 options be the option we want.
23 black cards out of 35 total cards can also be written as [tex]\frac{23}{35}[/tex], which is the probability that a black card is chosen.

If a single 2 hp motor draws 13.8 amps on 115 volt ac current, how much current would 9 identical motors pull?
what is the answer and how do you solve it?
The current drawn by 9 identical motors will be 124.2 amps current
Current is the flow of electrical charge carriers like electrons. Current flows from negative to positive points. The SI unit for measuring electric current is the ampere (A). One ampere of current is defined as one coulomb of electrical charge moving past a unique point in a second.
since , one motor of 2hp draws = 13.8 amps current
hence , 9 identical motor will pull = 13.8 * 9 (each will pull same amount of current )
