Answer:
[tex]c=\dfrac{27}{40}\\[/tex]
Step-by-step explanation:
We are required to solve for c in the equation: [tex]\dfrac{1}{8}+c= \dfrac{4}{5}[/tex]
Step 1: Collect like terms
[tex]\dfrac{1}{8}+c= \dfrac{4}{5}\\c= \dfrac{4}{5}-\dfrac{1}{8}[/tex]
Step 2: Find the Lowest Common Multiple of the denominators
LCM of 8 and 5 is 40
Step 3: Multiply all through by 40
[tex]40c= \dfrac{4}{5}*40-\dfrac{1}{8}*40[/tex]
Step 4: Simplify
40c=32-5
40c=27
Step 5: Divide both sides by 40 and simplify if possible.
[tex]c=\dfrac{27}{40}\\[/tex]

You spin the spinner twice.
What is the probability of landing on a 4 and then landing on a 4?
Simplify your answer and write it as a fraction or whole number.
Answer: 1/16
Step-by-step explanation: It's important to understand that the two spins are called independent events because the outcome of the first spin does not affect the outcome of the second spin.
To find the probability of independent events, we first find the probability of each event, then we multiply the probabilities together.
Since there is one 4 on the spinner and four possible outcomes, each of which is equally likely, the probability of spinning a 4 is 1/4.
This mens that 1/4 is the probability of
getting a 4 on the second spin too.
Now we multiply.
1/4 x 1/4 gives us 1/16.
So the probability of spinning a 4 twice is 1/16.

2-4(3x-y)=8(4-y)-39x and 8(4-y)-39x=6(y-x)
Answer:
X = -(146/123) , Y = 21/41
Step-by-step explanation:
2-4(3x-y) = 8(4-y)-39x2-12x-4y = 32-8y-39x
39x-12x+8y-4y = 32-2
27x+4y = 30
27x+4y-30 = 0
8(4-y) -39x = 6(y-x)32-8y-39x = 6y-6x
32-8y-6y-39x+6x = 0
-33x-14y+32 = 0

Answer:
Step-by-step explanation:
In a math class with 28 students, a test was given the same day that an assignment
was due. There were 18 students who passed the test and 23 students who completed
the assignment. There were 16 students who passed the test and also completed the
assignment. What is the probability that a student who passed the test did not
complete the homework?
Answer:
Probability that a student who passed the test did not complete the homework = 0.07
Step-by-step explanation:
Given:
Total number of students = 28
Number of students who passed the test = 18
Number of students who completed the assignment = 23
Number of students who passed the test and also completed the assignment = 16
To find: probability that a student who passed the test did not complete the homework
Solution:
Probability refers to chances of occurrence of some event.
Probability = number of favorable outcomes/total number of outcomes
Let A denotes the event that students passed the test and B denotes the event that students completed the assignment
P(A only) = [tex]P(A)-P(A\cap B)[/tex]
Here,
[tex]P(A)=\frac{18}{28}\,,\,P(A\cap B)=\frac{16}{28}[/tex]
So,
[tex]P(A\,\,only)=\frac{18}{28}-\frac{16}{28}=\frac{2}{28}=\frac{1}{14}=0.07[/tex]
Therefore,
probability that a student who passed the test did not complete the homework = 0.07

What is the slope of the line that passes through the poiņts (-10, 4) and (-10,8)?
Write your answer in simplest form.
Answer:
Slope is undefined
Step-by-step explanation:
Slope is calculated by [tex]\frac{y1-y2}{x1-x2}[/tex] so now you put the points (-10,4) and (-10,8) into that.
Since both x values are the same you can tell that the line is a vertial line meaning the slope is undefined.

The roads that connect three buildings form a right triangle. Use the image to find the distance between the library and the museum.
Answer:400 yards
Step-by-step explanation:Let L represents the position of library, R represents the restaurant and M represents the museum,
Since, By the given diagram,
∠MLR = 90°,
LR = 300 yd,
RM = 500 yd,
So, by the Pythagoras theorem,
By substituting the values,
Hence, the distance between library and museum is 400 yards.
If 5,x,y,40 are in geometrical progression, find x and y respectively.
Answer:
x = 10, y = 20
Step-by-step explanation:
Because this is a geometric sequence, we'll call the rate of change z. Because 40 is 3 terms away from 5, we can write 5 * z * z * z = 5z³ = 40.
z³ = 8 → z = 2
Now, we simply multiply 5 by 2 to get x, which is 10, and then we multiply x by 2 to get 10 * 2 = 20 for y. Hope this helps!
1521 orange trees are planted in a garden in such a manner that there are as many trees in a row as there are rows in the garden. The number of trees in each row is
Answer: 39
Step-by-step explanation:
Total number of orange trees = 1521
Note :
There are as many trees in a row as there are rows in the garden.
Therefore :
Number of rows in the garden = number of trees in a row
Let the number of rows in the garden = y
Hence, the number of trees in a row also = y
Total number of trees in the garden = number of trees in a row × number of rows in the garden
Total number of trees in the garden = y × y
1521 = y × y ; 1521 = y^2
y = √1521
y = 39
Answer:
no.f trees in each row =39Step-by-step explanation:
Total number of orange trees = 1521
Note :
There are as many trees in a row as there are rows in the garden.
Therefore :
Number of rows in the garden = number of trees in a row
Let the no.f trees in each row =x
let the no.f rows=x
therefore total no.f trees =x raised to 2
x raised to 2 =1521
therefore x=39
there fore no.of rows =39
no.f trees in each row =39When a data set contains values that tend to be around a central value with no bias left or

Please help!! Urgent! Due soon! - A bedroom is initially squat-shaped with each side x feet long.

Answer:
The second one; x²+7x+12
Step-by-step explanation:
So, since the beginning lengths of the square is x and x, the area of the square is x².
But then, you add 3 to one length, so that side is now (x+3), and then you add 4 to the width, so that is now (x+4).
Finally, you would multiply them together to get the equation you would use to find the new area.
For this, you would cross-multiply everything together; the x in the length by the x in the width, the x in the length by the 4 in the width, the 3 in the length by the x in the width, and then the 3 in the length by the 4 in the width. Now, all you have to do is add all of these together to get your answer.
Here's the work:
