If it's just the 7 that's repeating, let
x = 0.1777...
Then
10x = 1.777...
100x = 17.777...
100x - 10x = 17.777... - 1.777...
90x = 16
x = 16/90 = 8/45
If both 1 and 7 are repeating, let
x = 0.171717...
Then
100x = 17.171717...
100x - x = 17.171717... - 0.171717...
99x = 17
x = 17/99

A. Both area rate and flow rate would increase.
B. Area rate would increase, and flow rate would decrease.
C. Area rate would decrease, and flow rate would increase.
D. Both area rate and flow rate would decrease.
The effect of this change should be option D. Both area rate and flow rate would decrease.
Information regarding speed:In the case when the first gear is shifted so it increased the engine speed. While on the other hand, it reduced the tractor speed. Due to this, the area rate and the flow rate should be decreased.Learn more about the speed here: https://brainly.com/question/24772838

Which is the solution to the following system x+2y+z=9
X-y+3z=13
2z=10
Step-by-step explanation:
I'm not sure but,here you go
2z = 10
z = 10 ÷ 2 = 5
x + 2y + z = 9
x + y + 3z = 13
____________
x + 2y + 5 = 9
x + y + 3(5) = 13
_____________
x + 2y = 9 - 5
x + y = 13 - 15
___________
x + 2y = 4
x + y = -2 (×-1)
___________
x + 2y = 4
-x - y = 2
___________
y = 6
x = -2y - z + 9 = -2(6) - 5 + 9 = -12 - 5 + 9 = -8
If you wanna check,
x + y +3z = 13
(-8) + 6 + 3(5) = 13
x = -8 , y = 6 , z = 5
I'm not very sure but here you go,I might be wrong^^

Benjamin rents a storage unit that is shaped like a cube. There are 12 identical storage units in each row of the facility. If each storage unit has a volume of 125 cubic feet, what is the length of each row in the facility?
Answer:
60 Ft.
Step-by-step explanation:
125 Cubic Ft divided by 25 gets the length of a unit and that is 5. 5 times 12 is 60.
What is the hypotenuse of a right triangle if the legs are each 20 inches long? Round to the nearest whole number. A. 28 B. 29 C. 30 D. 31
Answer:
The answer is A.
Step-by-step explanation:
You have to apply Pythagoras Theorem :
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
[tex]let \: a = 20,b = 20[/tex]
[tex] {c}^{2} = {20}^{2} + {20}^{2} [/tex]
[tex] {c}^{2} = 800[/tex]
[tex]c = \sqrt{800} [/tex]
[tex]c = 28 \: (nearest \: whole \: no.)[/tex]
P.S (Take note):
Pythagoras Theorem can only applied in right angle triangle.
Answer:
We can find the hypotenuse by using the Pythagoras theorem/theory. The Pythagoras theorem states that,
[tex]h^{2}[/tex] = [tex]p^{2}[/tex] + [tex]b^{2}[/tex] where, h = hypotenuse, p = perpendicular, b = base
=> [tex]h^{2}[/tex] = [tex]20^{2}[/tex] + [tex]20^{2}[/tex]
=> [tex]h^{2}[/tex] = 400 + 400
=> [tex]h^{2}[/tex] = 800
=> h = [tex]\sqrt{800}[/tex]
=> h = 28.284.....
Therefore rounded to the nearest whole number, we get,
h = 28

Solve the two steps equations below and check your solution R/2-8=16
Answer:
r= 48
Step-by-step explanation
r/2 - 8 = 16
+8 +8
r/2 = 24
multiply both sides by two so it cancels out and you get r by itself.
the 2 cancels out and 24 times 2 = 48
r= 48

Rosalie and Emmet are having a disagreement. Rosalie thinks a line can have a line of symmetry, while Emmet
disagrees. What do you think: can a line have a line of symmetry? Why? Explain completely.
A line totally can have a line of symmetry. while it does not have width (therefore cannot put the line of symmetry through its "width"), it does have a length like any other shape. If we take a 4 unit line, we could put the line of symmetry at the 2 unit mark.
^sorry, im rushing a bit so you might have to paraphrase !
Answer:
Rosalie is correct, a line can have a line of symmetry.
Step-by-step explanation:
If you draw a line, a line of symmetry to that line would be perpendicular to the original line. Because lines are straight, they have an infinite number of lines of symmetry.
The graph that is made up of two straight lines, which has an absolute maximum or absolute minimum, and is symmetric belongs to the
function family.
Answer:
This may be a function of the absolte value family.
f(x) = IxI.
f(x) = x if x ≥ 0
f(x) = -x if x ≤ 0
Where this is the parent function, and the graph is shown below in green.
If the coefficient is positive, then the lines open upwards, and we will have a minimum (in this case, when x = 0).
And also in this case, we have symmetry around the value x = 0.
Now, the vertex can also be an absolute maximum if the coefficient is negative, like in the example shown below in color blue (the equation for the blue graph is f(x) = -3*IxI )
Find the equation of the line that passes through the point (1,2) with a slope of 4. Plug in your values for a and b into the equation below.
y = ______x+_______
Answer:
y=4x-2
you can find the y intercept if you plot a confirmed point on a graph and follow the slope to the line.
Answer:
y = 4x - 2
Step-by-step explanation:
Since we are given the slope already, we can solve for the y-intercept using the slope, the given point, and the formula [ y = mx + b ]
y = 4x + b
2 = 4(1) + b
2 = 4 + b
-2 = b
Substitute with what we solved for into the formula.
y = 4x - 2
