If you have 5 blue marbles, 8 yellow marbles, and 2 green marbles. What is the probability of pulling a yellow marble?
Answer: 8/15
Step-by-step explanation: take all the color of marbles and add them together. There is where you get your denominator of 25. Next, since you are finding for yellow marbles, take the number of yellow marbles (8) and that will be your numerator.
Hurrrryyyyy plllzzz. Determine the equation of the line that passes through the given points
(10,2) and (-3,2)
y = 2
Step-by-step explanation:To determine the equation of the line that passes through (10,2) and (-3,2), we need to determine the slope of the line. Then substitute the slope and any given point in point slope form to obtain the equation of the line.
Finding the Slope of the line:[tex]\implies \text{Slope} = \dfrac{\text{Rise}}{\text{Run}} = \dfrac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
[tex]\implies \text{Slope} = \dfrac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
Substitute the coordinates of the given points:
[tex]\implies \text{Slope} = \dfrac{2 - 2}{-3 - 10 }[/tex]
Simplify the equation to determine the slope:
[tex]\implies \text{Slope} = \dfrac{0}{-3 - 10 }[/tex]
∴ 0 divided by ANY number is ALWAYS 0.
[tex]\implies \text{Slope} =0[/tex]
Finding the equation of the line:Point slope form formula: y - y₁ = m(x - x₁)
x₁ and y₁ are the coordinates of any given point.m is the slopeSubstitute the values in the point slope form:
[tex]\implies \text{Equation of line:} \ y - y_{1} = m(x - x_{1} )[/tex]
[tex]\implies \text{Equation of line:} \ y - 2 = 0(x - 10)[/tex]
Simplify the equation to determine the equation of the line:
∴ Any number multiplied by 0 is 0.
[tex]\implies \text{Equation of line:} \ y - 2 = 0[/tex]
[tex]\implies \text{Equation of line:} \ y = 0 + 2[/tex]
[tex]\implies \text{Equation of line:} \ y = 2[/tex]
Thus, the equation of the line is y = 2.

Find the ratio of the given one: 20/200 = 0.1
this means the sugar (y) is 0.1 amount of soda (x)
Multiply the amount of soda by 0.1:
Formula is y = 0.1x
Formula : y = kx or y = k/x
Thus since the formula is y = kx then we can substitute:
y = 20
k = ?
x = 200
20 = ? / 200
? = 10
Therefore for the rest of the blank
100/10 = 10
500/10 = 50
1000/10 = 100
So the chart now is:
| Drink (x ml) | 200 | 100 | 500| 1000|
| Sugar (y g) | 20 | 10 | 50 | 100 |

What is the probability of picking a 5 and then picking a 5?
Write your answer as a fraction or whole number.
Answer:1/169 i think
Step-by-step explanation:
Because you have to get a 5 twice in a row your first probability for one would be 4/52 or 1/13 but because you have to do it twice in a row you multiply the odds together 1/13*1/13=1/169

What are the x- and y-intercepts of the graph of 5x – 4y = 20?
Answer:
The x-intercept is (4, 0)
The y-intercept is (0, -5)
Step-by-step explanation:
The x-intercept is always (x, 0)
Knowing this we can sub 0 for y in the equation so we can find the x-intercept
[tex]5x-4y=20\\5x-4(0)=20\\5x=20[/tex]
Now solve for x
[tex]5x=20\\\frac{5x}{5} =\frac{20}{5} \\x=4[/tex]
The x-intercept is (4,0)
The y-intercept is always (0, y)
Knowing this we can sub 0 for x in the equation so we can find the y-intercept
[tex]5x-4y=29\\5(0)-4y=20\\-4y=20[/tex]
Now solve for y
[tex]-4y=20\\\frac{-4y}{-4} =\frac{20}{-4} \\y=-5[/tex]
The y-intercept is (0, -5)

What number represents 8 times as many as 2
answer: 16
explanation: 8*2=16
The number that represents 8 times as many as 2 is 16.
The times in the question is nothing but multiplying a number with another number.
To find the number that represents 8 times as many as 2.
we need to multiply 2 by 8.
Two times eight is equal to sixteen.
2 × 8 = 16
Therefore, the number that represents 8 times as many as 2 is 16.

Identify the polynomial that is the difference of two squares.
A. 25m2 − 16n
B. 49m2 − 81n4
C. 36m2 − 8n8
D. 9m2 − 5n6
Answer:
Option B, [tex]49m^2 - 81n^4[/tex]
Step-by-step explanation:
Step 1: Determine the difference of two squares
According to online, "In mathematics, the difference of two squares is a squared number subtracted from another squared number. Every difference of squares may be factored according to the identity a^2-b^2 = in elementary algebra." a^2 - b^2 gives us (a + b)(a - b)
The only one that would work is Option B so lets factor it out.

Joshua has a ladder that is 12 ft long. He wants to lean the ladder against a vertical wall so that the top of the ladder is 11.8 ft above the ground. For safety reasons, he wants the angle the ladder makes with the ground to be no greater than 75°. Will the ladder be safe at this height? Show your work and draw a diagram to support your answer.

just multiply first paranthesis with second one. They are each 1 unit as there are no addition or subtraction inside the parantehsis so DON'T distribute. It's more simple.
(12ab^4c)*(5a)
now multiply these 2 paranthesis, again just 2 units to multiple.
