Solve the system: 10x-9y=8 21y+15x=0.5
PLEASE HELP NEED ASAP
Answers
Answer:
x = 1/2
y = -1/3
Step-by-step explanation:
10x - 9y = 8 (Multiply by 3)
15x + 21y = 0.5 (Multiply by -2)
30x - 27y = 24
-30x - 42y = -1
-69y = 23
y = -1/3
10x - 9y = 8
10x - 9(-1/3) = 8
10x + 3 = 8
10x = 5
x = 1/2

You pull a marble from a bag with 20 red 20 white and 10 green marbles. You hold onto it and then pull another marble. What is the probability of pulling a red marble and then pulling a green marble?
Answers
The probability of pulling a red marble and then pulling a green marble is,
⇒ 3 / 5
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
We have to given that;
You pull a marble from a bag with 20 red 20 white and 10 green marbles.
Here, Total number of marbles = 20 + 20 + 10
= 50
Thus, The probability of pulling a red marble is,
⇒ 20 / 50
⇒ 2 / 5
And, The probability of pulling a green marble is,
⇒ 10 / 50
⇒ 1 / 5
Therefore, The probability of pulling a red marble and then pulling a green marble is,
⇒ 2 / 5 + 1 / 5
⇒ 3 / 5

A survey of Mrs. Ramirez's students showed that 30
students will have pizza fonlunch, 17 will have macaroni
and cheese, 12 will have a hamburger, and 5 will have
chicken fingers. Suppose Mrs. Ramirez surveys all 1 200
students in the school. How many students can she
expect to choose hamburgers for
Hunch?
Answers
Answer: 480
Step-by-step explanation:
We can create a ratio for this!
We have:
[tex]\frac{number of hamburgers}{total students}[/tex]= [tex]\frac{new number of hamburgers}{new number of students}[/tex]
We can use substitution to input the information we already know:
[tex]\frac{12}{30}[/tex] = [tex]\frac{x}{1200}[/tex]
Using cross multiplication, we get:
1 200(12) = 30x
14,400 = 30x
[tex]\frac{14,400}{30}[/tex]=[tex]\frac{30x}{30}[/tex]
x = 480
Hope this helps! :)
The number of students expect to have hamburgers for lunch is 225 students.
What is a word problem?
A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Mrs. Ramirez's survey on students
Number of students have pizza = 30
Number of students have macaroni and cheese = 17
Number of students have a hamburger = 12
Number of students have chicken fingers = 5
Total number of students = 64.
Now, Mrs. Ramirez surveys all 1 200 students.
Then number of students expect to choose hamburgers for lunch can be found by,
[tex]\frac{Number of students have hamburgers}{Total number of students} = \frac{Number of students expect to have hamburgers}{ Total number of students}[/tex]
Let x be the number of students expect to have hamburgers.
⇒ [tex]\frac{12}{64}=\frac{x}{1200}[/tex]
⇒ [tex]x=\frac{(12)(1200)}{64}[/tex]
⇒ [tex]x=225[/tex]
Hence we can conclude that the number of students expect to have hamburgers for lunch is 225 students.

The image of the labeled spinner isn't attached
Answer:
Kindly check explanation
Step-by-step explanation:
Answering hypothetically ;
First create a sample space using the label of the two spinners ;
Each space will be the sum of the possible number that shows up on each turn of the spinner.
From the sample space, count the number of spaces where, the sun is greater than 4, that is the required outcome ; = x
Then the total number of samples in the sole space = total possible outcomes = y
Hence,
P(obtaining a sum greater than 4) = required outcome / Total possible outcomes

Formula : -
Ar ( rectangle ) = lb
lb
= ( x + 3 ) ( 2x + 1 )

Answer:

Step-by-step explanation:
We know that angle JNK is equal to angle MNL. We also know that angle JNK and angle KNL are supplementary.
Knowing this, we can write two equations: [tex]4x-1=3y+9[/tex] and [tex](4x-1)+(2x+6y+19)=180[/tex]. We can solve for y in the first equation. Subtracting 9 from both sides gives us [tex]4x-10=3y[/tex]. Dividing both sides by 3 gives us [tex]\frac{4x-10}{3} =y[/tex].
We can plug that in to the second equation to get [tex](4x-1)+(2x+6(\frac{4x-10}{3} )+19)=180[/tex]. Expanding the second parenthesis, we get [tex]2x+8x-20+19[/tex] which equals [tex](10x-1)[/tex]. We now have [tex](4x-1)+(10x-1)=180[/tex]. Expanding gives us [tex]14x-2=180[/tex]. Adding 2 to both sides gives us [tex]14x = 182[/tex]. Dividing both sides by 14 gives us [tex]x=13[/tex].
We can now plug 13 into the above equation to solve for y. [tex]y= \frac{4*13-10}{3}[/tex] Solving that gives you [tex]y=14[/tex].
To the nearest tenth of a centimeter what is the length of side ab
Answers
The length of side AB in the given triangle is 22.6. The correct option is the first option 22.6
Calculating the side length of a triangleFrom the question, we are to determine the length of side AB in the given triangle.
Using the law of sines, we can write that
AB/sinC = BC/sinA
From the diagram,
C = 50°
BC = 19
A = 40°
Thus,
AB/sin50° = 19/sin40°
AB = (19 × sin50°) / sin40°
AB = 22.6433
AB ≈ 22.6
Hence, the length is 22.6

a. Cos Ɵ = 2/5 find Tan Ɵ
b. Cosec Ɵ = 7/3 find Cos Ɵ
c. Cot Ɵ = 4/3 find Sec Ɵ
d. Tan Ɵ = 3 find Cosec Ɵ
Answers
Answer:
a.
cos θ = 2/5, tan θ = ?
tan θ = sin θ / cos θ tan θ = √sin² θ / (2/5) tan θ= 5√(1 - cos²θ) / 2 tan θ = 5√(1 - 4/25) / 2 tan θ = 5√(21/25) / 2 tan θ = √21 / 2b.
cosec θ = 7/3, cos θ = ?
cosec θ = 1/ sin θ cosec θ = 1/ √(1 - cos²θ) √(1 - cos²θ) = 1 / cosec θ1 - cos²θ = (1 / (7/3))² cos²θ = 1 - 9 / 49cos²θ = 40/49cos θ = √40/49cos θ = 2√10/7c.
cot θ = 4/3, sec θ = ?
cot θ = cos θ / sin θcos θ = cot θ * sin θcos θ = 4/3 * √(1 - cos²θ)9cos²θ = 16(1 - cos²θ)25cos²θ = 16cos²θ = 16/25cos θ √16/25cos θ = 4/5sec θ = 1/ cos θsec θ = 1/ (4/5)sec θ = 5/4d.
tan θ = 3, cosec θ = ?
sin²θ + cos²θ = 11 + cos²θ/sin²θ = 1/ sin²θ1 + 1/tan²θ = cosec²θ1 + 1/9 = cosec²θcosec²θ = 10/9cosec θ = √(10/9)cosec θ = √10 / 3To find the diameter of a circle, multiply its radius by two. True or faulse
