a. It takes the robot 4/35 hour to complete one tasks
b. The number of tasks the robot can complete in one hour is 8 3/4 tasks
ProportionFrom the question, we are to determine how long it takes the robot to complete one task
From the given information,
A robot can complete 7 tasks in 4/5 hour
If the robot can complete 7 tasks in 4/5 hour
Then,
The robot will complete 1 task in 4/5 ÷ 7 hour
4/5 ÷ 7
= 4/5 × 1/7
= 4/35
Hence, it takes the robot 4/35 hour to complete one tasks
b.
Let the number of tasks the robot can complete in one hour be x
If the robot can complete 7 tasks in 4/5 hour
Then,
The robot will complete x tasks in 1 hour
4/5 × x = 7 × 1
4/5 × x = 7
4 × x = 7 × 5
4x = 35
x = 35/4
x = 8 3/4
Hence, the number of tasks the robot can complete in one hour is 8 3/4 tasks

The point (-2,8) is on the graph of y=f (x), which point must be on the graph of y=-f(x)
The point on the graph y = -f(x) is (-2 , -8)
According to the question the coordinates we have been given is (-2 , 8) and it is on the graph y = f(x)
That is we have been given that
f(-2) = 8 (1)
Now we have to find the point on the graph y = -f(x)
So we will choose the value of x = -2 in f(x)
Thus, putting the required value we get
y = - f(-2)
As the value of f(-2) is 8 from equation (1). we will equate the value in the above equation we get
y = -(8)
y = -8
Hence the point on the graph is (-2 , -8)

The meaning of the point (378,9) is with 9 yards of yarn, Paula can knit 378 knot hats.
Given that:-
The number of hats h she can knit varies directly with the amount of yarn y in yards she has.
Also, the constant of proportionality is 42.
Hence, we can write,
h ∝ y
h = ky

Applying the triangle proportionality theorem, the value of x and the value of y are:
C. y = 5, x = 10.
How to Apply the Triangle Proportionality Theorem?Since lines m and n are said to be parallel lines, therefore, according to the triangle proportionality theorem, the ratios below can be created.
4/12 = y/15 [proportional sides]
Cross multiply
(y)(12) = (4)(15)
12y = 60
Divide both sides by 12
12y/12 = 60/12
y = 5
x = 15 - y
Plug in the value of y
x = 15 - 5
x = 10
Thus, applying the triangle proportionality theorem, the value of x and the value of y are:

Answer:
9.2
Step-by-step explanation:
You want the distance between A(2, 0) and B(0, 9).
DistanceThe distance formula is based on the Pythagorean theorem. It tells you the distance between (x1, y1) and (x2, y2) is ...
d = √((x2 -x1)² +(y2 -y1)²)
For the given points, this becomes ...
d = √((0 -2)² +(9 -0)²) = √(4+81) = √85
d ≈ 9.2
The distance between A and B is about 9.2 units.

Answer:
True statements are 4 and 5
Step-by-step explanation:
This s basically using set theory to evaluate line segments
The union of two(or more) sets is the set of elements that are in either or both sets.
Here is an example
If set A = {1, 2, 3, 4} and set B = {3, 4, 5, 6} then
A ∪ B = (1, 2, 3, 4, 5, 6}
Note that there cannot be any duplicates in a set
We have to treat the line segments as sets to solve this problem.
For easier explanation, I am going to view each segment as having points which I am labeling 1, 2, 3 etc.
The individual independent line segments are JL, LM, MN, and NT, basically each is a set of the points that comprise each segment
You have to visualize each of these line segments as being comprised of these points.
Note that these are distinct sets ie there is no common point when we consider the above 4 sets
Let set
JL have the points {1, 2, 3} we say JL = {1, 2, 3}
LM = {4, 5}
MN = {6, 7}
NT = {8, 9}
We see that there are no common points between each of the four sets below
1. JL ∪ MN = set of points that lie in JL or MN or both. Since JL and MN are distinct sets, the union of these two sets is s
JL U MN = {1, 2, 3} U {5, 6} = {1, 2, 3, 5, 6} . However, JM contains all the points from J to M which is {1, 2, 3, 4, 5} which is not the same as JL U MN
So Statement 1 is false
2. JL U MN = {1, 2, 3} U {6, 7} = {1, 2, 3, 6, 7} so it contains more points than MN{6, 7} and therefore Statement 2 is false
3. LM U LN
We can see that LN contains all the points in LM and MN = {4, 5, 6, 7}. LM U LN = {4, 5} U { 4, 5, 6, 7} = {4, 5, 6, 7}. But LM is only a subset of LN and has fewer points {4, 5} so Statement 3 is false
4. LM U LN
LM = {4, 5}, LN = {4, 5, 6, 7} so LM U LN = {4, 5, 6, 7} = LN. Remember sets don't duplicate. So Statement 4 is True
5. NT U JT
NT = {8, 9} and JT = set of all points in the segment from J to T which is all the points. So JT = {1, 2, 3, 4, 5, 6, 7, 8, 9} and NT U JT = {1, 2, 3, 4, 5, 6, 7, 8, 9} which is the set of all points in JT. Therefore Statement 5 is True
The figure below shows a graphical representation of what I wrote above. If you look at LN for instance, it has 4 points {4, 5, 6, 7} and therefore represents all the points in LM and LN (without duplication of points). This is Statement 4, by the way

16 and 2/7 miles per hour
Zendaya will travel $ 1 and 17/21 of a mile per hour on her roller skates.
Zendaya travels $5 and 3/7 of a mile in 3 hours on her roller skates. We can simply write this statement in mathematical form as,
Total distance covered by Zendaya in 3 hours on her roller skates = $( 5 + ( 3/7 ) of a mile
Total distance covered by Zendaya in 3 hours on her roller skates = $ ( ( 35 + 3)/7 ) of a mile
Total distance covered by Zendaya in 3 hours on her roller skates = $ ( 38/7 )
Total distance covered by Zendaya in 1 hours on her roller skates = $ (( 38/7 )/3 ) = $ (38/21) of a mile
or we can write also write ( 38 /21 ) miles per hour as ( 1 and 17/21 ) miles per hour.

The other graphs fail the vertical line test. For instance, in the upper right corner we have a vertical line through x = -1 which passes through more than one point. The input x = -1 leads to multiple outputs y = -1 and y = 3 at the same time.

Movie b costs 5 dollars
Movie theater got 200 dollars and sold 47 ticket
How many tickets did movie a sell
Solving a system of equations, we conclude that 35 tickets for movie a were sold
How many tickets did movie a sell?
Let's define the variables:
x = tickets of movie a sold.y = tickets of movie b sold.Here we know that a total of 47 tickets were sold, then:
x + y = 47
And they sold for a total of $200, then:
x*$4 + y*$5 = $200
So we have a system of equations:
x + y = 47
x*$4 + y*$5 = $200
We want to solve this for x, then we need to isolate the variable y in one of the equations, doing that in the first one we get:
y = 47 - x
Now we can replace that in the other equation to get:
x*$4 + (47 - x)*$5 = $200
x*$4 + $235 - x*$5 = $200
$235 - x*$1 = $200
$235 - $200 = x*$1
$35 = x*$1
$35/$1 = x = 35

You have 2 positive numbers. One number is one-fifth of the other number. The difference between the two numbers is 308, find the numbers. PLEASE HELP
Answer:
[tex]77, 385[/tex]
Step-by-step explanation:
Start by writing the equations in symbolic form. I will represent one number with an x and the other with a y.
One number is one-fifth of the other number:
[tex]x=\frac{1}{5}y[/tex]
The difference between the two numbers is 308:
[tex]y-x=308[/tex]
This difference is positive, therefore I am assuming that y is the larger number. In the first equation, I made x a part of y, so this should check out.
Now we have a system of equations:
[tex]\left \{ {{x=\frac{1}{5}y } \atop {y-x=308}} \right.[/tex]
I will rewrite the first equation for simplicity:
[tex]5x=y[/tex]
Now, I will substitute y from the first equation for y in the second equation:
[tex]5x-x=308[/tex]
Simplify:
[tex]4x=308\\x=77[/tex]
Now, use x to find y using the second equation:
[tex]y-77=308\\y=385[/tex]
Now, I can check the solutions by plugging them into the first equation!
[tex]x=\frac{1}{5}y\\ 77=\frac{1}{5}(385)\\77=77[/tex]
The solution is correct!

A triangle with the coordinates listed below is reflected across the x-axis. What are
the new coordinates?
A(5,-2) B(0, 3) C(-4,1)
A(5,-2) B(0, -3) C(-4,1)
A'(5, 2) B'(0, -3) C'(-4,-1)
A(-5, -2) B(0, 3) C(4, 1)
A(-5, 2) B(0, -3) C(4, -1).
The reflection of the triangle gives the co-ordinates A'(5, 2) B'(0, -3) C'(-4,-1) .
In mathematics, a reflection is a mapping from a Euclidean space to itself that is an isometry with a set of fixed points known as the hyperplane; this set is also known as plane of reflection or the axis. The mirror image of a figure in the axis or plane of reflection is the image produced by a reflection.
When an object is reflected across the x -axis , the image will be at same distance from the x axis as the object or point is on the cartesian plane.
So if a point P has the co-ordinates (x , y) . When reflected across the x-axis the the reflection has the co-ordinates P'(x , -y ) .
The co-ordinates of the 3 points are A(5,-2) B(0, 3) C(-4,1).
When reflected across the x-axis the co-ordinates become :
A(5,-2) →A'(5,2)
B(0, 3)→B'(0,-3)
C(-4,1)→C'(-4,-1)
Hence the second option is correct, the reflected image of the triangle has the coordinates A'(5, 2) B'(0, -3) C'(-4,-1) .
