What is the scale factor from L to S
Answer:
-2
Step-by-step explanation:
Triangle S
Base = 2Height = 4Triangle L
Base = 4Height = 8For the base you must multiply 4 by -2 to get 2. Likewise for the height you must multiply 8 by -2 to get 4. Thus the scale factor from L to S is -2

Explain what is the difference between radius
and circumference
Answer:
The circumference is the perimeter, specifically the perimeter of a circle. It can be solved by using the following formula:
C = 2πr
C stands for circumference.
π stands for pi, or 3.14 (rounded).
r stands for radius.
The radius is the distance from the center point of the circle to any point on the circle. It is denoted by the variable, r, as stated above. It is 1/2 of the diameter.
Answer:
the radius is the line from center to perimeter and circumference is the enclosed boundary
Step-by-step explanation:
radius- is any of the line segments from a circle or spheres center to its perimeter
circumference- the enclosed boundary a curved geometric figure, especially a circle

What is the answer ?
Answer and Step-by-step explanation:
To find out the answer, we need to first find how much money it is to buy 1 kg of almonds.
So, do 34 divided by 4.
[tex]\frac{34}{4} = 8.5[/tex]
Now, multiply 8.5 by 5.
8.5 × 5 = 42.5
The cost for 5 kilograms of almonds is $42.5

PLEASE HELP COMPARING RATIOS
Answer:
8 minutes per customer in Restaurant One.
6 minutes per customer in Restaurant Two.
7 minutes per customer in Restaurant Three.
Restaurant Two had the fastest service.
Method:
I divided the time it took – for example – 48 divided by 6. I would do this because I wanted to find out each person took (6 people), and the amount of time it took for each person to get their food. I would use division for this problem because I am finding how much each person took out of the whole time.
Answer
The 2nd restaurant is the fastest
Step-by-step explanation:
I. Compare Time per Customers
When 1st restuarant = 48/6 = 9
2nd restuarant = 42/7 = 6
3rd restuarant = 63/9 = 7
Given if in 1 min, I can serve 20 customers = 1/20 = 0.05
in 1 min, He can serve 10 customers = 1/10 = 0.1
See the different? I can serve better than him.
So The answer is the 2nd restuarant.
Hope that help :D

Supposed a certain game is fair and costs $4 if you lose and has a net payoff of $9 if you win. The only
possible outcomes of the game are winning and losing.
What is the probability of winning?
Answer:
32.5% Win Rate
Step-by-step explanation:
I got this answer by first:
( 9 ) * x + ( -4 ) * ( 1 - x ) = 0
9x - 4 + 4x = 0
13x = 4
then finally:
13/4 = 3.25 | And to get that into percent you multiply that by 10, giving you a 32.5% win rate. or 325 / 1000. Meaning you will win 325 out of 1000 games you play. Hope this helped!
Probability of winning is 0.69.
What is probability?Probability denotes the possibility of the outcome of any random event. The meaning of this term is to check the extent to which any event is likely to happen.
According to the question
Supposed a certain game is fair and costs $4 if you lose and has a net payoff of $9 if you win.
The only possible outcomes of the game are winning and losing.
The probability of winning = [tex]\frac{9}{4+9}[/tex]
= [tex]\frac{9}{13}[/tex]
= 0.69
Hence, probability of winning is 0.69.

What is the solution to the system of equations below?
y = -5x - 1
4x - 7y = 7
Hi
When you have a system of equation, you generally have two unknowned value.
The trick is to express one letter as equal of something in the second letter.
We have two lines :
(1) : y = -5x-1
(2) : 4x-7y = 7
Here he job is half done as we have already "y" express in " x" with line (1) so : y = -5x-1
So I can rewrite line (2) as this : 4x-7y = 7
as y = -5x-1 so :
4x-7y = 7 become :
4x - 7 ( -5x-1) = 7
4x-7 * (-5x) - 7* (-1) = 7
4x +35x +7 = 7
4x +35x +7 -7 = 7-7
39x = 0
39x/39 = 0 /39
x = 0
So if X = 0 then we have in line (1) we have by replacing "x" by it's value : y = -5x-1
y = -5*0 -1
y = -1
Dont hesitate to ask in comments if it's still not clear.

Answer:
p is 16
Step-by-step explanation:
[tex]p \: \alpha {(q + 2)}^{2} [/tex]
introduce a constant on a right hand side:
[tex]p = k {(q + 2)}^{2} - - - eqn \: (a)[/tex]
[ when q is 1, also p is 1 ]
[tex]1 = k(1 + 2) {}^{2} \\ 1 = 9k \\ k = \frac{1}{9} [/tex]
substitute for k in eqn (a):
[tex]p = \frac{1}{9} (q + 2) {}^{2} [/tex]
so, when q is 10:
[tex]p = \frac{1}{9} (10 + 2) {}^{2} \\ \\ p = \frac{1}{9} (144) \\ \\ p = 16[/tex]

A spinner is divided in to fourths and is labeled 1-4. John spins the spinner and tosses a coin. What is the
probability of spinning a 1 and flipping heads?
Answer:
1/8 or 12.5% probability
Step-by-step explanation:
Compound probability is what you would want to use here which is the probability of the first event multiplied by the second event.
So, if 1/4 is the probability of spinning a 1 on the spinner and 1/2 is the probability of flipping heads, you would multiply 1/4 • 1/2 to get 1/8, or 12.5%

Answer:
((down below))
Step-by-step explanation:
If A is the midpoint of Line Segment XY, then we can conclude that the length of XA = the length of AY. ((in other words, XA = AY))
Find XA
Insert equations // 2x = 10x - 8It's best to solve for "x." So we do this by flipping the equation (you can do this in any way you want, but this seemed easier) // 8 = 10x - 2x8 = 8x // Divide for x // x = 1Finding the Length of AY (Calculating Length)
Substitute x = 1 from XA // 10(1) - 8We get an answer of 2 ((this is the length of AY))Finding the Length of XA
Substitute x = 1 from XA // 2(1)We get an answer of 2 ((this is the length of XA)Finding the Length of XY
XA = AY // the length of XA is 2 (or 2 units, or whatever you are measuring in) and the length of AY is 2, then finding the length of XY means adding both lengths togetherXA = AY = 2 = 2 = 2 + 2 = 4 ((the length of XY is 4))
