A jar contains nine blue marbles, eight yellow marbles, 11 black marbles, and 12 red marbles.
Without looking, what is the probability of pulling a white marble from the jar?
1
0
3/10
9/40
Answer:
0%
Step-by-step explanation:
The first thing you need to do, is add the total of all of the marbles together.
9 + 8 + 11 + 12 = 40.
Knowing this, you can take the amount of white marbles, (0) and put this against the 40 total marbles.
Since there are 0 white marbles in the jar, you know that it is impossible to pull one out of the jar.
0%
Answer: The answer is 0, because there is 0 white marbles in the jar to begin with.
A 25 foot ladder leans against a house. How far is the foot of the ladder from base of the building if the top of the ladder is 30 feet from the ground?
Answer:
15ft
Step-by-step explanation:
Because the Pythagorean theorem stats [tex]A^{2}+B^{2}=C^{2}[/tex] the first leg, the unknown leg would be A. The leg that is the side of the house would be substituted in for B. The length of the ladder would be C. Thus [tex]x^{2}+20^{2}=25^{2}[/tex], then you would simplify it to [tex]x^2+400=625[/tex] then you would subtract 400 from both sides. Then that would equal [tex]x^{2}=225\\[/tex]. Then you would square root both sides giving you [tex]x=15\\[/tex].

The height of a flare fired from a 32-foot high platform can be modeled by the function h= -16t^2 + 16t + 32, where h is the height in feet above the ground and t is the time in seconds. Find the time it takes the flare to reach the ground
Answer:
Time, t = 2 seconds
Step-by-step explanation:
The height of a flare fired from a 32-foot high platform can be modeled by the function :
[tex]h= -16t^2 + 16t + 32[/tex]
Here, h is the height in feet above the ground and t is the time in seconds.
It is required to find the time taken by the flare to reach the ground. When its reaches ground, height covered by it equals 0 such that,
h = 0
[tex]-16t^2 + 16t + 32=0\\\\t=\dfrac{-16+\sqrt{16^2-4\times (-16)(32)} }{2(-16)}, \dfrac{-16-\sqrt{16^2-4\times (-16)(32)} }{2(-16)}\\\\t=-1\ s, 2\ s[/tex]
Neglecting t = -1 seconds, the time taken by the flare to reach the ground is 2 seconds.

pls answer the question cause I really need the answer to this question
Answer:
y = 3x + 2
Step-by-step explanation:
So we can use the point-slope equation to help us figure out our y = mx +b equation
First we need to choose two points on the graph so we can calculate our slope
I personally like to choose point that intersects two numbers perfectly on the line rather than a point that is maybe half way between two numbers
So we can use the point (0,2) and the point (2,8)
Our (0,2) will represent (x₁, y₁) and our (2,8) will represent (x₂,y₂)
The equation to find the slope is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1} }[/tex], so plugging in our values, we get [tex]m=\frac{8-2}{2-0} =\frac{6}{2} =3[/tex]
We have found our slope, 3, and now we can use the point-slope equation: y - y₁ = m(x - x₁) to figure out the remainder of the equation.
Plugging in our values we get: y - (2) = (3)(x - (0)) which simplifies to y - 2 = 3x which then simplifies to y = 3x + 2

In the system 4x + 9y = 7 and and 4x - 9y = 9, would I add or subtract this system to solve for x? To solve for y?
add to solve for x or add to solve for y
subtract to solve for x or subtract to solve for y
add to solve for x and subtract to solve for y
subtract to solve for x and add to solve for y
Answer:
add to solve for x and subtract to solve for y
Step-by-step explanation:
To solve for any variable, it is required to eliminate the other variable in two variable - two equation set.
The set of equations are
4x + 9y = 7 __________1
4x - 9y = 9 ___________2
To solve for x we need to eliminate Y
We see that in equation 1 there is 9y and
in equation 2 there is -9y
if we add 9y and -9y (9y -9y = 0)
Hence it is clear that to solve for x , it is needed to add equation 1 and equation 2.
by adding equation 1 + equation 2 we have
4x + 9y = 7 __________1
=> 4x - 9y = 9 ___________2
=>4x + 9y + 4x -9y = 7 +9
=>8x = 16
=>x = 16/8 = 2
____________________________
To solve for y we need to eliminate x
We see that in equation 1 there is 4x and
in equation 2 also there is 4x
if we subtract 4x and 4x (4x -4x= 0) , we get 0
Hence it is clear that to solve for y , it is needed to subtract equation 2 from equation 1.
by performing equation 1 - equation 2 we have
4x + 9y = 7 __________1
=> 4x - 9y = 9 ___________2
=>4x + 9y -( 4x -9y) = 7 - 9
=>4x + 9y - 4x +9y = -2
=>18y = -2
=>y = -2/18 = -1/9
_____________________________
Thus, correct answer is
add to solve for x and subtract to solve for y
Answer: The answer is add to solve for x and subtract to solve for y, I hoped this helps, brainliest please? :)

Jackson gave Lena this expression to evaluate: 14(8 + 12). Lena said that to evaluate the expression was simple; just multiply the factors 14 and 20. Jackson told Lena she was wrong. He solved it by finding the product of 14 and 8 and then adding that to the product of 14 and 12.
a. Evaluate the expression using each student’s method.
b. Who was right in this discussion? Why?
Answer:
In this discussion, they both got the same answer, so they're both right. However, when Jackson said Lena was wrong, he was incorrect, because Lena's way was also correct. So, they were both right in this discussion when it comes to the answers, but Jackson was wrong when he said lena was wrong. (I hope this helped).
Step-by-step explanation:
Lena: 14(8 + 12)
14(20)
280
Jackson: 14 x 8 = 112
14 x 12 = 168
168 + 112 = 280

One of those fraction type questions, that I don’t know
Answer:
C
Step-by-step explanation:
To solve this problem, we need to first find the ratio of numbers less than four to total numbers.
There are 3 numbers on the wheel less than 4 (1, 2, and 3). There are 8 total numbers, meaning the ratio of numbers less than 4 to total numbers is 3:8.
Now, we need to find the probability of spinning a white number. There are 3 white numbers on the wheel (3, 5, 8). However, one of these numbers (3) is less than 4, so it is already accounted for in the previous ratio. There are 2 numbers left, meaning the ratio of remaining white numbers to total numbers is 2:8.
Adding this to the original equation, we get 5:8. As a fraction, 5:8 = 5/8. The answer that correctly highlights this is C.

Find the area of a regular pentagon with an apothem of 11 units. *
364 square units
O 440 square units
516 square units
O 166 square units
Answer:
440 square unitsStep-by-step explanation:
We can find half of a side of the pentagon with the expression
[tex]tan(36\°)=\frac{s_{half} }{11}[/tex]
Because, as a regular polygon, all its sectors have the same central angle, and the apothem divides equally each sector in two equal parts.
[tex]s_{half} \approx 8[/tex]
Therefore, half of a side is 8 units long, which means each side measures 16 units.
Now, the area of a penthagon is defined by
[tex]A=\frac{p \times a}{2}[/tex]
Where [tex]p[/tex] is the perimeter and [tex]a[/tex] is the apothem. Where the perimeter is the sum of all sides, which is 80 units.
[tex]A= \frac{80 \times 11}{2} =440 \ u^{2}[/tex]
Therefore, the right answer is the second choice.

In the diagram below, AB is parallel to CD. What is the value of x?
A. 30
B. 60
C. 150
D. 120
Answer:
C. 150
Step-by-step explanation:
x° + 30° = 180°...(sum of interior angles)
x° = 180° -30°
x°= 150°
x= 150
The value of x° in the given diagram is 150°. This is obtained by using the pair of interior angles formed along a transverse when passing through parallel lines.
What are the interior angles?The angles that lie inside or in-between region of the parallel lines when a transverse passes through them are said to be pair of Interior angles. These angles are on the same side of the transverse.The sum of these angles is 180°.What are the verticle angles?The verticle angles are opposite to each other when two lines are intersected at a point. Those angles are the same in size.
Calculating the angle x:It is given that line AB is parallel to line CD and transverse is making angles with these lines.
The angles are x° and 30°.
The angle of 30° is at the exterior side of these lines at the point of intersection of line CD and the transverse line. So, it forms a verticle pair of angles with the angle opposite to it.
Thus, the angle opposite to it also becomes 30°. This opposite angle lies inside the parallel lines. So it forms a pair of interior angles with a given angle x.
Since we know that sum of pair of interior angles = 180°, we get
x° + 30° = 180°
⇒ x° = 180° - 30°
⇒ x° = 150°
∴ x = 150°
Thus, the angle x = 150°. So, option C is correct.

Step-by-step explanation:
32+112=144
Answer:
352
Step-by-step explanatioThe shape as you can see is a trapezoid. To find the area of the trapezoid is base 1 + base 2 x height. I multiplied 26 and 16 which made the whole shape 416. Now, we need to take away the white triangle which will show in the end the area of the shaded figure. To find the area of the triangle, you need to do 8x16 then divide by 2. 8 x 16= 128 feet. Then we divide that number by two which equals 64. The area of the unshaded triangle is 64 feet. Finally, we take 416 and subtact 64, which equals 352.
