0.5353... Repeating
0.7777 Non-repeating
Step-by-step explanation:
A repeating decimal is a decimal number with a digit (or group of digits) that repeats forever.
There are three ways to show a repeating decimal:
Several duplicates of the repeating digit or block of digits, followed by an ellipsis, e.g. 0.3333... or 0.123123...A dot or a line above a repeated digit, e.g. [tex]\sf 0.\.{3}[/tex] or [tex]\sf 0.\overline{3}[/tex]A line above a repeating block of multiple digits, e.g. [tex]\sf 0.\overline{123}[/tex][tex]\sf 0.19\overline{2}[/tex]
This is a repeating decimal as the line over the "2" means that this digit repeats forever.
[tex]\sf 0.\overline{314}[/tex]
This is a repeating decimal as the line over the "314" means the group of digits 314 repeats forever, e.g. 0.314314314...
0.5353...
This is a repeating decimal as there are two duplicates of the repeating block of digits "53" followed by an ellipsis.
0.7777
This is non-repeating decimal as there are no dots or lines above any of the digits, nor an ellipsis after the repeating digits.

What is a fraction?
Any number of equal parts is represented by a fraction, which also means a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.
Here, we have
Based on the given conditions, formulate: 3 1/4 - 2 1/2
Remove the parentheses: 3 + 1/4 - 2 - 1/2
Reorder and combine like terms: (3-2)+1/4 - 1/2
Calculate the sum or difference: 1+ 1/4 - 1/2
Expand the fraction to get the least common denominator: 4/(1×4) + 1/4 - 2/(2×2)
Calculate the product or quotient: 4+1/4 - 2/(2×2)
Calculate the product or quotient: 4 + 1/4 - 2/4
Write the numerators over the common denominator: 4 + 1 -2/4
Calculate the sum or difference: 5 - 2/4
Calculate the sum or difference: 3/4
Hence, the fish's position with respect to the water's surface at 4:00 p.m. is 3/4.

The graph of two functions is shown.
graph of f of x equals negative x squared plus x and g of x equals x minus 1
If x = −1 is a solution to f(x) = −x2 + x and g(x) = x − 1, why is it also a solution to f(x) = g(x)?
a
It is a solution to f(x) = g(x) because it is the x-intercept of the two graphs.
b
It is a solution to f(x) = g(x) because it is the y-intercept of the two graphs.
c
It is a solution to f(x) = g(x) because it is the x-coordinate where the two graphs intersect.
d
It is a solution to f(x) = g(x) because both graphs are negative at x = −1.
The correct option is c. It is a solution to f(x) = g(x) because it is the x-coordinate where the two graphs intersect.
How to determine why x = −1 is also a solution to f(x) = g(x)?
x = −1 is also a solution to f(x) = g(x) because it is asking for the values of x that make f(x) equal to g(x). In this case, x = −1 is a value that makes both f(x) and g(x) equal to −1, so it is a solution to the equation f(x) = g(x).
The graph of f(x) = g(x) is simply the set of all points that are on both the graph of f(x) and the graph of g(x)
These points are the points where the two graphs intersect. In this case, the graph of f(x) = g(x) is a single point at x = −1, which is the x-coordinate where the two graphs intersect

Is (r-4) a factor of 6r^4-17r^3-46r^2+77r-20? What are the steps and how would you know if it’s a factor?
Answer:
see explanation
Step-by-step explanation:
By the Factor theorem, if (x - a) is a factor of f(x) then f(a) = 0
if (r - 4) is a factor then substituting r = 4 into the polynomial should result in it having a value of zero, that is
6[tex]r^{4}[/tex] - 17r³ - 46r² + 77r - 20 ( substitute r = 4 )
= 6[tex](4)^{4}[/tex] - 17(4)³ - 46(4)² + 77(4) - 20
= 6(256) - 17(64) - 46(16) + 308 - 20
= 1536 - 1088 - 736 + 288
= 0
Then (r - 4) is a factor of the polynomial
If 3% of a number equals 15, find 12% of that number.
Answer: 60
Step-by-step explanation:
3 / 100 * x = 15
3x = 1500 multiply both sides by 100
x = 500
500x0.12 = 60
The 12 percentage of the number is A = 60
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let's call the number we're looking for N
We can set up an equation based on the information given:
0.03N = 15
To solve for N, we can divide both sides by 0.03:
N = 15 / 0.03
N = 500
So the number we're looking for is 500
Now , the percentage value is = 12 %
And , we can find 12% of that number by multiplying it by 0.12:
A = 0.12 x 500 = 60
Hence , 12% of the number is 60.

The mass of the Earth is 5.97 × 1024 kg and the mass of Jupiter is 1.90×10²7.
This expression can be used to find the ratio.
What is the ratio of the mass of Earth to the mass of Jupiter?
The ratio of the mass of Earth to the mass of Jupiter is equal to 3.14*10⁻³, thus option B is correct.
What is ratio?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls)
Given, the mass of Earth = 5.97*10²⁴ kg
Also, mass of Jupiter = 1.90*10²⁷ kg
Hence, ratio of mass of Earth to Jupiter is calculated by dividing mass of Earth upon the mass of Jupiter.
Ratio = (5.97*10²⁴/1.90*10²⁷ )
= 3.14*10²⁴⁻²⁷
= 3.14*10⁻³
Thus, the ratio of the mass of Earth to the mass of Jupiter is equal to 3.14*10⁻³, thus option B is correct.

What is a quadrilateral?
A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined.
Given that ABCD is a quadrilateral.
The diagonal AC divides the quadrilateral into 2 triangles △ABC and △ACD.
The length of sides AC and CB of the △ABC is same. Thus △ABC is isosceles triangle. Therefore ∠BAC = ∠ABC = x°.
Similarly, the length of sides AC and CD of the △ADC is same. Thus △ADC is isosceles triangle. Therefore ∠CAD = ∠CDA = 66°
Given that ∠DCB = 90°.
∠A = ∠CAD + ∠BAC = 66° + x°
The sum of all interior angle of a quadrilateral is 360°.
Therefore,
∠A + ∠B + ∠C + ∠D = 360°
66° + x° + x° + 90° + 66° = 360°
Add to the like terms:
222 + 2x = 360
Subtract 222 from both sides:
2x = 138
x = 69

Answer:
The answer is 81.85%
Step-by-step explanation:
Given;μ = 116σ = 14The z score is used to determine by how many standard deviations the raw score is above or below the mean.
The z score is given by:
z = x - μ/σ
where,
x = raw scoreμ = meanσ = standard deviationFor x = 88
z = 88 - 116/14
z = (-2)
For x = 130
z = 130 - 116/14
z = (1)
Thus,
P(88 < x < 130) = P(-2 < z < 1)
= P(z < 1) - P(z < -2)
= 0.8413 - 0.0228 = 81.85%
Thus, 81.85% of the population would be between 88 and 130.

These are some basic laws in maths that helps us to simplify the complicated expressions easily
Solution:
Here we can first distribute the power 7 to both 5 and 5th root of x by exponent laws
we get 5^7 * 5th root(x)^7
now we know nth root(x) = x ^1/n
we will do the same as
we get 5^7 * x^7/5 which is our required answer and there many more properties of exponents that we study in higher classes
