harmony places the letters of December into a bag. a letter will be randomly selected and not replaced. then the other letter will be selected. what is the probability of harmony selecting a C and then E?
Answer:
1/56
Total letters are 8
probability of first selecting c is 1/8 and since it's not replaced, probability of selecting e is 1/7
Total probability= 1/8*1/7=1/56
Therefore, total probability is 1/56

The equation of a line is y=3.6x+2. What is the rise and run of the slope?
Answer:
The rise is 3.6 and the run is 1
Step-by-step explanation:
The rise is 3.6 and the run of the slope is 1
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
where (x₁, y₁) and (x₂, y₂) are the two points that you are trying to find the slope between.
Given that the equation of a line is y=3.6x+2.
By comparing the equation of straight line y = mx + c
Therefore, m = 3.6
Thus, the slope of the line is 3.6
We can conclude that the rise is 3.6 and the run is 1.

Describe the possible lengths of the third side of the triangle given that the lengths of the other two sides are 12 feet and 18 feet.
I attached the picture too.
Answer:
6 ft < L₃ < 30 ft
Step-by-step explanation:
To obtain the answer to the question given above, we must bear in mind that:
The sum of the length of two sides of any triangle is always greater than the 3rd length i.e
L₁ + L₂ > L₃
With the above information in mind, we can obtain the answer to the question given above as follow:
Length 1 (L₁) = 12 feet
Length 2 (L₂) = 18 feet
Length 3 (L₃) =..?
Case 1:
L₁ + L₂ > L₃
12 + 18 > L₃
30 > L₃
L₃ < 30 feet
Case 2:
L₁ + L₃ > L₂
12 + L₃ > 18
Collect like terms
L₃ > 18 – 12
L₃ > 6 feet
Thus,
6 feet < L₃
Combining case 1 and 2,we obtained:
6 ft < L₃ < 30 ft
Therefore, the possible Lenght of the 3rd side is : 6 ft < L₃ < 30 ft

Fracciones
Si un todo se divide en partes iguales o desiguales expresadas en fracciones, entonces la suma de esas fracciones debe ser 1, es decir, el 100% del todo.
Tenemos 40 alumnos como el total del grupo de sexto. Cuatro quintas partes de ellos llevaron las tareas completas, eso significa que:
[tex]\frac{4}{5}*40 =32[/tex]
alumnos llevaron las tareas completas. Para conocer el número de alumnos que no llevaron las tareas completas, restamos el total del anterior, es decir, 40-32=8 alumnos no llevaron la tarea completa.

P=2(5x+8y+7)
P=10x+16y+14
9. 3a+a^2+5a-10 = a^2+8a-10
10. 8v+8w+7v+14w = 15v+22w
11. 4c^2+6c+6c^2-2c = 10c^2+4c

In the problem we’re supposed to find the value of x that makes ABC ~ RST I can’t figure it out can someone please help
Answer:
Step-by-step explanation:
if the triangles are similar then their sides are in proportion ( or you can think that they make equivalent fractions like 2/3 = 4/6 )
44/ (x+2) = 20/7 = 3x+1 /5 ( all of those are equivalent fractions)
use that [tex]\frac{a}{b} =\frac{c}{d}[/tex] is the same as a*d = b*c
[tex]\frac{44}{x+2} =\frac{20}{7}[/tex] is the same as 20(x+2) = 7*44
20x +40 = 308; subtract 40 from both sides
20x = 268; divide by 20 both sides
x= 13.4

Answer:
the answer is 46
Step-by-step explanation:
8 + 20 + 18 = 46
i hope this helps
Answer:
? = 45
Step-by-step explanation:
Since the triangles are similar, we can use proportions
20 20+8
------- = -------
? ? + 18
20 28
------- = -------
? ? + 18
Using cross products
20 ( ? +18) = = ? * 28
Distribute
20 ? + 360 = 28 ?
Subtract 20 ? from each side
360 = 8?
Divide each side by 8
360/8 = ?
45 = ?

Answer:
Step-by-step explanation:
we have 105 marbles
number of blue marbles= x
green marbles= x+25
x+x+25=105

Answer:
(B) y = x - 8
Step-by-step explanation:
The slope is found by looking at the change in y divided by the change in x.
The line goes through grid intersections that differ both horizontally and vertically by 1 unit, so ...
m = rise/run = 1/1 = 1
The y-intercept is where the line crosses the y-axis, at y = -8. The slope-intercept equation is then ...
y = mx + b . . . . m = slope (1); b = y-intercept (-8)
y = x - 8 . . . . matches choice B

i need help asap
Answer:
You can multiply the brackets to make sure you get 4x² + 4x + 1. Since the numbers in the brackets are the same, we can just use one of them and let it equal to 0. Then solve it. ∴ The answer is x = -1/2.
Step-by-step explanation:
4x2+4x+1=(2x+1)2 or (2x+1)(2x+1)

work out three numbers that are in both sequences and between 20 and 40 write the numbers on a single line
Answer:
The nth term of a sequence is 2n + 1
The nth term of a different sequence is 3n ï€ 1
Work out the three numbers that are
in both sequences
and
between 20 and 40
Now the three numbers I managed to get are 25, 31 and 37 (as I assumed it meant the output of both of these sequences needs to be the same as well as being in between 20 and 40). For example 2x18+1= 37 as does 3x12+1= 37
