Kaya had a string 6 1/8 inches long. She cut off a piece 2 3/4 inches long. How long is the remaining piece of string? Show your work. Write your answer as a mixed number.
Answer: 3 3/8
Step-by-step explanation:
We know that for example 2/4=4/8 so it is multiplied by 2. In this problem the fractions are 2 2/4 and 6 1/8. We are subtracting so you would first multiply the fraction that’s going to subtracted from the other fraction 2 3/4= 2 6/8. Now that we have our fractions we can subtract 6 1/8-2 6/8 this would leave us with 3.375 which is equal to 3 3/8.
Answer:
3 3/8
Step-by-step explanation
If you take away 2 3/4 from 6 1/8 it would equal 3 3/8 how you get that answer I'm not really sure but I used google 0_0 but there you go I hope it helped-
the slope of (2,11) and (10,4)
Answer:
-7/8
Step-by-step explanation:
the formula for calculating slope for the given coordinates is:
(y2-y1)/(x2-x1)
so (2,11) = (x1,y1)
and (10,4) = (x2,y2)

Step-by-step explanation:
Planets Mars, Neptune, Earth, Saturn
Diameter (km) 6770 49244 12742 116460
The least diameter is of mars, then is of the earth, then Neptune and the greatest in the list is of Saturn.
The list of least to greatest would be
Mars, Earth, Neptune, Saturn
The mars is farther to the sun as compared to the earth. As the planet moves away from the Sun it's orbit becomes bigger and bigger. Neptune is the eigth planet and saturn is the sixth planet.

Answer:
(1,0)-------Increases------X=0-----Decreases to negative infinity
Step-by-step explanation:
Value of function f(x) = logx at axis (1,0) is zero.
What is graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
The graph of the logarithmic function y=logx is shown.
The domain of function f(x) = logx is the set of all positive real numbers.
1. f(x)=logx domain of the logirthimic function is (0, ∞).
2. The range is the set of all real numbers.
3. The function is continuous and one-to-one.
4. The y-axis is the asymptote of the graph.
5. The graph intersects the x-axis at (1,0). That is, the x-intercept is 1.
Value of function f(x) = logx at axis (1,0)
⇒ f(x) = 0
Thus, value of function f(x) = logx at axis (1,0) is zero.

help asap! ill give the best to person who explains it clearly
Answer:
The answer is D.
Step-by-step explanation:
First, you have to find the area of circle using the formula :
A = π × r²
A = π × 3²
A = 9π
Given that PHU is an equilateral triangle so all sides have a degree of 60°. Next, you have to find the area of minor sector of P and U by using the formula :
A = (θ/360) × π × r²
A = (60/360) × π × 3²
A = 1.5π
Lastly, you have to subtract the area of sector from the area of circle in order to find the area of shaded region :
A = (9π × 2) - (1.5π × 2)
A = 18π - 3π
A = 15π

What is the polar form of Negative 2 StartRoot 3 EndRoot minus 6 i?
Answer:
4√3 [cos (2π/3) + isin(2π/3)]
Step-by-step explanation:
We are to write out the polar form of:
-2√3 - 6i
In Mathematics:
The polar form of a given complex number a + bi is given as r[cos(θ)+isin(θ)],
where r =√a²+b²and
θ = arc tan (b/a) when a is > 0
or arc tan (b/a) + π or arc tan (b/a) + 180 when a is < 0
From the above question:
-2√3 - 6i
We have that
a = −2√3 and b = −6
Hence:
r =√a²+b²
r = √(-2√3)² + (-6)²
r = √(4 × 3) + 36
r = √12 + 36
r = √48
r = √16 × 3
r = 4√3
a is < 0
Hence,
θ = arc tan (b/a) + π
θ = arc tan (-6/-2√3) + π
θ = 2π/3
Substituting 4√3 for r and 2π/3 for θ in:
r[cos(θ)+isin(θ)]
-2√3 - 6i = 4√3 [cos (2π/3) + isin(2π/3)]

O July 1, 1979
O June 17, 1997
O June 1, 1997
Answer:
June 7th, 1979
Step-by-step explanation:
1979 comes before 1997, so that eliminates those. Then June comes before July. So June 7th, 1979.
June 7, 1979, is the earliest date. Option A is correct.
How to represent the date?The recommended format for writing dates is YYYY-MM-DD, which stands for year, month, and day.
Since 1979 came before 1997, those are disregarded. June, therefore, precedes July. So, it's June 7, 1979.
The earliest date is June 7, 1979.
Hence option A is correct.

Describe the error made in subtracting the two rational expressions shown
Answer:
The minus sign between the two fractions was not distributed correctly.
Step-by-step explanation:
The error made in this solution of rational fractions' subtraction is that the minus sign between the two terms will change the signs of numerator of second fraction so the numerator in the answer will be 3.
The correct solution is:
[tex]\frac{1}{x-2} - \frac{1}{x+1}\\=\frac{x+1}{(x-2)(x+1)} - \frac{x-2}{(x-2)(x+1)}\\=\frac{x+1-(x-2)}{(x+1)(x-2)}\\=\frac{x+1-x+2}{(x+1)(x-2)}\\=\frac{3}{(x+1)(x-2)}[/tex]
Hence,
The error was in the last step of subtraction.
Answer:
You must subtract all terms of the numerator being subtracted out, not just the first term.
The negative 2 should have been subtracted out to get a numerator of x+1 - x+2
The simplified numerator of the difference should be 3, not –1.

A square with a side of y is transformed into a rectangle by adding 10 to one side and then subtracting 10 from another. Express the new area as a polynomial
Answer: [tex]y^2-100.[/tex]
Step-by-step explanation:
if we have a square with sides 'y' units,
then, its breadth = length = y
If we add 10 to one side it will become (y+10) (longer one) and subtract 10 from another, then it will become (y-10) (shorter one).
Area of rectangle = breadth x length
So, area of rectangle [tex]= (y+10)(y-10)[/tex]
[tex]= y^2-10^2=y^2-100\ \ \ \ \ [(a-b)(a+b)=a^2-b^2][/tex]
Hence, the new area as a polynomial = [tex]y^2-100.[/tex]
