A point lies on AB¯¯¯¯¯ and is located 3/7 the distance from A to B. What are the coordinates of the point? (4, 3) (7, 3) (9, 3) (12, 3)
Answer:
(4,3)
Step-by-step explanation:
This doesn't even take any math really, just deductive reasoning :)
We know the line segment stretches from one to 15, meaning there are 14 points on the line as there is (1,2,3, etc.)
14/2 obviously equals 7, so just plug it in from there.
12 is too far up on the line to be less than half, so (12, 3) is wrong
^ this goes for (9, 3) as well
7 is literally the halfway marker, so there is no way it could be (7, 3)
Making the answer (4, 3) because not only is it the last one remaining but it makes the most sense, being less than one half of the segment

Briefly explain how to convert a fraction to its decimal
form.
Answer:
you just divide
Step-by-step explanation:
Just divide the top of the fraction by the bottom, and read off the answer!
Answer: So what my teacher always told me to do was act like a fraction was a tree. The tree always falls to the left which then outs the fraction as a division problem. You solve the division problem
Step-by-step explanation:
Ok so for example, lets use [tex]\frac{1}{2}[/tex]. Drawing it as a tree it then falls to the left. Therefore it becomes 1 ÷ 2. So 2 can not go into one therefore you need to put a decimal point at the top and add a zero behind the 1 under the bar. The 1 then becomes a 10, therefore 2 can go into 10 5 times. However the answer is not 5. You have to remember to bring the decimal point that you placed before the 5. In conclusion hte answer is .5 . This may be confusing because I am not able to include any photos but hopefully you'll get the point.

Laura is 32 feet below the surface in a cave. If she ascends 8 feet, find her new position relative to the surface.
If Laura ascends 8 feet, her new position relative to the surface is 24 feet below the surface.
How to assign sign to the like and unlike algebraic expression coefficients?If the direction is same (like coefficients), we add them and if the direction is opposite (unlike coefficients) then we subtract them. The sign can be taken as per our convenience for a particular direction.
Similarly, as given, if Laura is 32 feet below the surface in a cave (say negative direction)
- 32 feet
and then further she ascends 8 feet that is upward direction (say positive direction),
+ 8 feet
then for calculating final distance of Laura position from surface, we get the expression as:
-32 + 8 = - 24
Hence the final result value is negative 24, it means Laura is bellow the surface, by the distance of 24 feet.

The solution to the given expression is -8 - 2r - p² - 6r² which is determined by performing the arithmetic operation.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The given expression is given in the question
(10 – 7r - p²) + (-6r² - 18 +5r)
Open the parentheses and rearrange the terms,
10 - 18 - 7r + 5r - p² - 6r²
Apply the arithmetic operation in the likewise terms,
-8 - 2r - p² - 6r²
Therefore, the solution to the given expression is -8 - 2r - p² - 6r²

AC=x+165,AB=48 and BC=2x+139. Find x
Answer:
Assuming A, B, and C are collinear and B is between A and C then x = -2 2Step-by-step explanation:
Assuming A, B, and C are collinear and B is beetween A and C
AB + BC = AC
48 + 2x + 139 = x + 165
2x + 187 = x + 165

Type the correct answer in each box. Use numerals instead of words. Consider this expression. (x+5)(x-7) Complete the box to show the distributive property applied to this expression.
In the top right corner is -7x since we multiply the x and -7
In the bottom row, we'll have 5x for the first box and -35 for the second box. Each box is the result of multiplying the outer values.
In the top left corner, the x^2 is from multiplying the two copies of x.
Victoria is going to use a computer at an internet cafe. The cafe charges an initial fee to use the computer and then an additional price per minute of usage. It is known that the total charge to use a computer for 5 minutes would be $6 and that the additional rate per minute of use is $0.60. Write an equation for C,C, in terms of t,t, representing the total cost of using a computer for tt minutes at the internet cafe.
Step-by-step explanation:
Given that the initial charge/fee for the first 5 minutes is $6
and also the additional rate per minutes is $0.6
we can model the total charges after the equation of a straight
that y= mx+c
now using the required notation
C= 0.6t+ 6
comparing this with the equation of a straight line
the constant term c is $6 flat rate for the first 5 minutes
the gradient 0.6 is m
the dependent variable x is t
and the cost C is y
Answer:
i believe its c=0.60t+3

How would I set up question one?
A straight line is 180 degrees:
25x + 8 + 9x + 2 = 180
Combine like terms:
34x + 10 = 180
Subtract 10 from both sides:
34x = 170
Divide both sides by 34:
X = 5
Now solve the smaller angle:
9x + 2 = 9(5) + 2 = 45 + 2 = 47
They angle with the y is a vertical angle to 47 so needs to also equal 47:
7y + 5 = 47
Subtract 5 from both sides:
7y = 42
Divide both sides by 7:
Y = 6
Answer: x = 5, y = 6

Step-by-step explanation:
Two times.
Or four times if the rectangle happens to be a square.
Cheryl wants you find the number of hours 7th graders do work at home each week. There are 297 boys and girls in 7th grade, Cheryl random surveyed 50 girls in the entire school to find a number of our 7th graders do homework each week described why she would get a biased sample
Answer: There are a total of 297 students in the 7th grade. Rough estimates would say that about half of that number are boys and half are girls. Asking only 50 random girls would be biased because not only would it not be all of the girls (the number of girls would be around 148 or 149) but it would also be ignoring the roughly 148 to 149 boys there are on estimate. The sample would be biased because it would be ignoring the opinions of more than half the seventh grade.
(FULL CREDIT TO maksimylian, I DID NOT WRITE THIS ANSWER)
Answer:
Randomly surveying 50 girls would most likely bring non-seventh-graders into the sample.
The sample also does not take any boys into account, and they most likely make up about half of the seventh-grade population.
The results would not be a representative sample of the population.
