What is the distance between (8, -3)(8,−3)left parenthesis, 8, comma, minus, 3, right parenthesis and (4, -7)(4,−7)left parenthesis, 4, comma, minus, 7, right parenthesis? Choose 1 answer:
Answer:
5.6568 units
Step-by-step explanation:
Given the following points :
(8, - 3) and (4, - 7).
Find the distance between them.
(8, - 3) : x1 = 8, y1 = - 3
(4, - 7): x2 = 4, y2 = - 7
Distance (d) = √[(x2 - x1)² + (y2 - y1)²]
d = √[(4 - 8)² + (-7 - (-3))²]
d = √[(-4)² + (-7 +3)²]
d = √[16 + (-4)²]
d = √16 + 16
d = √32
d = 5.6568
d = 5.66 units

What is the sum and classification of 3/20 + the square root of 10 and is it rational
Answer:
The correct option is 1
Step-by-step explanation:
Given the number . we have to identify the number is rational or irrational
As we know is irrational
i.e
The above number is irrational as it is non repeating and non-termination number after decimal.
As the sum of a rational and an irrational must be irrational
∴ is irrational which gives the sum 3.31227766....

Your school is 20 blocks east and 12 blocks south of your house. The mall is 10 blocks north and 7 blocks west of your house. You plan on going to the mall right after school. Find the distance between your school and the mall assuming there is a road directly connecting the school and the mall. One block is 0.1 mile. Round your answer to the nearest tenth of a mile.
Answer:
3.5 miles
Step-by-step explanation:
The straight line distance from the school to the mall is found using the Pythagorean theorem. That distance is the hypotenuse of a triangle that is 27 blocks in the east-west direction and 22 blocks in the north-south direction.
d = √(27^2 +22^2) = √1213 ≈ 34.83 . . . blocks
Since each block is 0.1 miles, the distance in miles is ...
distance to mall = (0.1 miles/block)(34.83 blocks) = 3.483 miles
Rounded to tenths, the distance from school to mall is 3.5 miles.

For each incorrect answer on a test, the teacher changes the total points possible by - 3
points. The total number of points possible on a test is 64. If a student has 8 incorrect
answers, what will be that student's score?
Answer:
40
Step-by-step explanation:
You would mutiply 8 times -3 and you would get -24 and 64 + (-24) = 64 - 24 which equals 40
The student's score on the test will be 40.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the mark for the correct answer is x
Then,
Correct marks(score) + incorrect marks = total marks
x + incorrect marks = total marks
x = total marks - incorrect marks
Now,
Total marks = 64
Incorrect marks = 8(3) = 24
So,
x = 64 - 24 = 40.
Hence "The student's score on the test will be 40".

Mary is traveling to Ecuador for her summer vacation. She looks at a map of the path of her flight. Her plane leaves from Florida, located at (1, 4) on the map’s coordinate grid, makes a stop at the midpoint, Panama, located at (5, 7 ) on the map’s coordinate grid. and then heads to its destination, Ecuador. Find the location of Ecuador on Mary’s map. Group of answer choices (3, 5.5) (8, 9) (0, 0) (9, 10)
Answer:
(9, 10)
Step-by-step explanation:
We are told that the coordinates of Mary's departure location is (1,4)
Now, we are told that She stopped at the midpoint of the journey located at Panama with a coordinate of (5, 7).
Now, we want to find the coordinates of her final destination.
Let the coordinates of her final destination be (x, y)
Since midpoint is at (5,7) and the initial point is at (1,4), then to get x;
(x + 1)/2 = 5
x + 1 = 5 × 2
x + 1 = 10
x = 10 - 1
x = 9
Similarly, to get y;
(y + 4)/2 = 7
y + 4 = 14
y = 14 - 4
y = 10
Thus, the coordinates of her final destination is; (9, 10)
Consider the segment AB with A positioned at (6,2). The midpoint of AB, M is located at (5, -3). What are the coordinates of point B? * O (7,7) O (4,-8) O (5.5, -0.5) O (4,5)
Answer:
I didn't "do the math" yet at all, but draw it out on an X,Y axis... Thinking about it logically... If point A is in the upper right quadrant of the axis, because both X and Y coordinates are positive numbers, so you go right on the horizontal axis and up on the vertical axis... Then the midpoint is in the lower right quadrant of the due to the X coordinate being a positive, thus you go right on the horizontal axis, but the Y coordinate is a negative, so you go down vertically... So point B cannot be above both the midpoint or point A, ruling out (7,7) and (4,5) as both Y coordinates of those answers (7 or 5) are higher than point A's Y coordinate of 2... B would have to be below point A because the midpoint is below point A with a Y coordinate of -3... So this leaves either option (5,-0.5) or option (4,-8)... However.... While (5,-0.5) has a lower Y coordinate than point A with -0.5, its Y coordinate is above the Y coordinate of the midpoint as well, since -0.5 is above -3... So this doesn't jive as point B cannot be between point A and the midpoint to point B... This logically leaves (4,-8) left to be the answer... And if you drew on an X,Y axis the coordinates (6,2) as well as (5,-3) and (4,-8), then connect the dots, you'd find (5,-3) sits about half ways between (6,2) and (4,-8)...
So (4,-8) is probably the answer...
The best way to come to this conclusion mathematically is finding the slope (rise over run) of point A and the midpoint between point A and point B, then continuing the slope down, etc... But this particular question with the multiple choice answers ruled all but 1 answer out...
To find the slope you take rise over run, which is the Y of the 2nd coordinate minus the Y of the 1st coordinate, divided by (or over) the X of the 2nd coordinate minus the X of the 1st coordinate....
IE: ( Y2 - Y1 ) / ( X2 - X1 ) = Rise / Run
So.... The 2nd coordinate's Y value is -3, and the 1st coordinate's Y value is 2... Subtract 2 from -3, and you get -5...
Then the 2nd coordinate's X value is 5, and the first coordinate's X value is 6... Subtract 6 from 5, and you get -1...
Divide -5 over -1, which equals the same as 5 over 1... The rise is 5, the run is 1, the slope is 5 steps vertically for every 1 step horizontally...
Or visually... ( -3 - 2 ) / ( 5 - 6 ) which is -5 / -1... Since both sides are negative, that's the same as 5 / 1... which is 5 vertical steps (rise) for every 1 horizontal step (run), or a slope of 5...
So add the slope rise of 5 to the Y coordinate of the midpoint, -3, and you get 2, which is the Y coordinate of point A... And add slope run of 1 to the midpoint X coordinate, 5, and you get 6, the X coordinate of point A... Now subtract the slope rise of 5 from the midpoint, -3, and you get -8... So that tells you that point B has to have a Y coordinate of -8.... And now subtract the slope run of 1 from the midpoint X coordinate, 5, and you get 4... The X coordinate of point B... Giving you a point B coordinate of (4,-8)...
Gracie can iron 3 shirts in 13 minutes. At this rate, how long will it take her to iron 10 shirts? Which proportion shows how to solve the problem?
Answer:
43 1/3 minutes to iron 10 shirts
Step-by-step explanation:
Number of shirts : Time taken
3 shirts : 13 minutes
10 shirts : x minutes
3 / 13 = 10 / x
Cross product
3 * x = 13 * 10
3x = 130
Divide both sides by 3
3x / 3 = 130 / 3
x = 43 1/3 minutes
x = 43 minutes 20 seconds
It will take 43 minutes 20 seconds to iron 10 shirts

A loading dock manager is unpacking a delivery truck that has 57 boxes of shoes and 26 boxes of socks. What is the ratio of boxes of socks to boxes of shoes
Answer:
0.4561
Step-by-step explanation:
If a loading dock manager is unpacking a delivery truck that has 57 boxes of shoes and 26 boxes of socks, the ratio of boxes of socks to boxes of shoes will be expressed as amount of boxes of socks : amount of boxes of shoes.
amount of boxes of socks : amount of boxes of shoes = 26:57
26:57 = 26/57
26/57 ≈ 0.4561
Hence the ratio of boxes of socks to boxes of shoes is approximately 0.4561
