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:

[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.

Yes, Gabby is correct. Lake city is warmer at 8F  than Ellenville.

Temperature is defined as the sum of the kinetic energies of all the atoms or molecules in a substance. The kinetic energy of a substance's constituent particles varies. A distribution can be used to depict the particles' kinetic energy at any particular moment.

Temperature is measured in Fahrenheit, Celsius and Kelvin.

As minus sign with the temperature depicts cold and hot and it have to do nothing with the calculation. The correct way is 14-6 = 8f. So Gabby is correct. We will not consider minus sign with six in calculations.

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:

The 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,

For 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.

The solution of the given system of equation is (6, 12). So the option c is correct.

In the given question, Carissa works as a babysitter during her summer vacation.

She gets paid one rate for daytime hours and a higher rate for nighttime hours.

One week, she worked 12 daytime hours and 4 nighttime hours and earned $120.

The next week, she earned $60 for a total of 4 daytime hours and 3 nighttime hours.

Let x represent the hourly daytime rate and y represent her hourly nighttime rate.

The system of equations is

12 x + 4 y = 120……………(1)

4 x + 3 y = 60……………(2)

We have to find the solution to the system of equations.

To find the solution for the system of equation we solve the given equation using elimination method.

Multiply equation by 3 on both sides, we get;

12x + 9y = 180

Subtract equation 3 and 1

12x+9y-(12x+4y)=180-120

12x+9y-12x-4y=60

5y=60

Divide by 5 on both side, we get;

y=12

Now putting the value of y in equation 2

4x+3×12=60

4x+36=60

Subtract 36 on both side, we get

4x=24

Divide by 4 on both side, we get

x=6

Hence, the solution of the given system of equation is (6, 12). So the option c is correct.

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

Factorization is the reverse process of expansion of mathematical expression to simple terms. The factorized term is: [tex]\frac{x + 14}{6}[/tex]

Factorization is a procedure in which a given number of terms of a mathematical expression is reduced by collecting common terms. It involves reducing a given mathematical expression to a simple form of terms.

Given that:

[tex]\frac{x^{2}+ 12x - 28}{6x^{2} }[/tex] ÷ [tex]\frac{x - 2 }{x^{2} }[/tex]

[tex]\frac{x^{2}+ 12x - 28}{6x^{2} }[/tex] x [tex]\frac{x^{2} }{x -2}[/tex]

[tex]\frac{x^{2} + 12x - 28}{6(x - 2)}[/tex]

Factorizing the numerator, we have;

[tex]x^{2} + 12x - 28[/tex] = (x - 2) (x + 14)

The ratio of the mass of Earth to the mass of Jupiter is equal to 3.14*10⁻³, thus option B is correct.

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

3 / 100 * x = 15

3x = 1500 multiply both sides by 100

x = 500

The 12 percentage of the number is A = 60

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 %

If the ratio of the measure of the three sides of the triangle is 9:7:5 and the perimeter is 191.1 inches, then the three sides of the triangle are 81.9 inches, 63.7 inches and 45.5 inches

The ratio of the measure of the three sides of a triangle = 9 : 7 : 5

Then three sides of the triangles = 9x, 7x and 5x

Where x is the constant

The  perimeter of the triangle = 191.1

The perimeter of the triangle is the sum of the three sides of the triangle

Then the equation will be

9x + 7x + 5x = 191.1

21x = 191.1

x = 191.1 / 21

x = 9.1

The first side = 9x

= 9 × 9.1

= 81.9 inches

The second side = 7x

= 7 × 9.1

= 63.7 inches

The third side = 5x
