[tex]\frac{25}{48}[/tex] represents repeating decimal

Solution:

We are asked to find the rational number that represents repeating decimal

A repeating decimal, also called a recurring decimal, is a number whose decimal representation eventually becomes periodic (i.e., the same sequence of digits repeats indefinitely)

Option 1

[tex]\frac{11}{40} = 0.275[/tex]

So here the decimal part is not repeating. So [tex]\frac{11}{40}[/tex] does not represent repeating decimal

Option 2

[tex]\frac{3}{25} =0.12[/tex]

So here the decimal part is not repeating. So [tex]\frac{3}{25}[/tex] does not represent repeating decimal

Option 3

[tex]\frac{25}{48} = 0.52083333333[/tex]

So here in decimal part "3" is repeating and goes on forever

So [tex]\frac{25}{48}[/tex] represents repeating decimal

Option 4

[tex]\frac{7}{32} = 0.21875[/tex]

So here the decimal part is not repeating. So [tex]\frac{7}{32}[/tex] does not represent repeating decimal

Answer:

95

Step-by-step explanation:

(80 + 95 + 90 + 80 + 100 + x) / 6= 90

x = 95

Answer:

95.

Step-by-step explanation:

The are a total of 6 numbers so  to make the mean 90 the total must be 6*90 = 540.

So the number in the blank is 540 - (80 + 95+90+80+100)

=  540 - 445

= 95.

Good morning,

Answer:

-19

Step-by-step explanation:

(5x−3)/2=3x+8 ⇌ 5x−3 = 2×(3x+8)  ⇌  5x−3 = 6x+16  ⇌ 6x-5x = -3-16

⇌ x=-19.

:)

Answer:

x = - 19

Step-by-step explanation:

Given

[tex]\frac{5x-3}{2}[/tex] = 3x + 8

Multiply both sides by 2 to clear the fraction

5x - 3 = 6x + 16 ( subtract 6x from both sides )

- x - 3 = 16 ( add 3 to both sides )

- x = 19 ( multiply both sides by - 1 )

x = - 19

Final answer:

The solution set graphic is C - Points on negative x-axis.

Explanation:

The correct solution set graphic for this question is C - Points on negative x-axis.

To determine the solution set graphically, you would need to plot all the possible values of the equation or inequality on a coordinate plane. Option A - Infinite set of points on the line would represent a linear equation or inequality with multiple solutions. Option B - Empty set would mean that there are no solutions to the equation or inequality. Option C - Points on negative x-axis would indicate that the equation or inequality has solutions only on the negative x-axis.

Answer:

The greatest common factor is 5.

Step-by-step explanation:

The prime factorisation of 10, 30 and 45 is,

10 = 2 × 5

30 = 2 × 3 × 5

45 = 3 × 3 × 5

The prime factor '5' is common in the factorisation of 10, 30 and 45

So, the greatest common factor of 10, 30 and 45 is 5.

Answer:

+20

Step-by-step explanation:

This is meaning to add when it says to gain

First, use distributive property:

5(2r+6)-12r  The original expression; multiply 5 by 2r, and 5 by 6.

10r+30-12r  Keep the -12r, just add it on to the end of the number(s) you found

Next, use communitive property:

10r+30-12r  What we found in the previous step

-2r+30        Combine the like terms; 10r-12r=-2r, then place the 30 at the end

Done! Your answer is -2r+30.

Hope that helps!

Answer:

A: Its legs are congruent

Step-by-step explanation:

A trapezoid is a quadrilateral with exactly one pair of parallel sides. In a trapezoid the parallel sides are called bases. A pair of angles that share a base as a common side are called a pair of base angles. A trapezoid with the two non-parallel sides the same length is called an isosceles trapezoid.

An isosceles trapezoid is a trapezoid with two congruent sides and congruent base angles.

An isosceles trapezoid is a trapezoid that has two congruent sides. In other words, the two non-parallel sides of an isosceles trapezoid are equal in length. The base angles of an isosceles trapezoid are also congruent. The parallel sides of an isosceles trapezoid are not equal in length.

For example, if a trapezoid has sides AB = 6 cm, BC = 5 cm, CD = 4 cm, and DA = 5 cm, then it is an isosceles trapezoid because sides BC and DA are congruent.

x = - 1 and x = - 7

Step-by-step explanation:

Given

x² + 8x + 7 = 0 ← in standard form

(x + 1)(x + 7) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 7 = 0 ⇒ x = - 7

Answer:

x=6

Step-by-step explanation:

16x-8+2x=100

18x-8=100

18x=100+8

18x=108

x=108/18

x=6

14x=108 is the equivalent equation of the equation 16x – 8 + 2x = 100.

Two or more expressions with an Equal sign is called as Equation.

The given equation is 16x – 8 + 2x = 100.

Sixteen times of x minus eight plus two times of x equal to hundred.

16x – 8 + 2x = 100.

We need to add the variable terms to get the equivalent equation.

Equivalent equation is an equation which looks different but the result will be same.

14x-8 = 100.

Add 8 on both sides.

14x=100+8

14x=108.

Hence, 14x=108 is the equivalent equation of the equation 16x – 8 + 2x = 100.

Answer:

Measurement of JL=8

Step-by-step explanation:

Given:-

[tex]\triangle JKL\ is\ right\ angle\ triangle[/tex]

[tex]m\angle J=62\ degree[/tex]

JK=17

[tex]sin\ 62\ degree= 0.88[/tex]

[tex]cos\ 62\ degree= 0.47[/tex]

[tex]tan\ 62\ degree= 1.88[/tex]

To find measurement of JL=?

Now,

[tex]cos\theta=\frac{adjacent\ side}{hypotenuse}[/tex]

[tex]cos\ 62\ degree=\frac{JL}{17}[/tex]

[tex]0.47=\frac{JL}{17}[/tex]

[tex]JL=0.47\times 17[/tex]

[tex]JL=7.99[/tex]

Answer:

He have 32 quarters and 15 dimes.

Step-by-step explanation:

Given:

Asa saves dimes and quarters so that he will have exact change for the bus.

He has 47 coins that are worth $9.50.

Now, to find the number of coin each he have.

Let the number of quarters be [tex]x.[/tex]

And the number of dimes be [tex]y.[/tex]

So, the total number of coins are:

[tex]x+y=47.[/tex]

[tex]y=47-x.[/tex].........(1)

As given the total worth of coins = $9.50

And the value of a quarter = $0.25 and the value of a dime = $0.10.

Now, the total worth of coins are:

[tex]0.25x+0.10y=9.50[/tex]

Putting the equation (1) in the place of [tex]y[/tex] we get:

[tex]0.25x+0.10(47-x)=9.50[/tex]

[tex]0.25x+4.7-0.10x=9.50[/tex]

[tex]0.15x+4.7=9.50[/tex]

Subtracting both sides by 4.7 we get:

[tex]0.15x=4.80[/tex]

Dividing both sides by 0.15 we get:

[tex]x=32.[/tex]

The number of quarters = 32.

Now, putting the value of [tex]x[/tex] in equation (1) we get:

[tex]y=47-32.[/tex]

[tex]y=15.[/tex]

The number of dimes = 15.

Therefore, he have 32 quarters and 15 dimes.

Answer:

The required points of the given line segment  are ( 9, - 2 ).

Step-by-step explanation:

Given that the line segment AB whose midpoint M is ( 4, 2 ) and point A is ( - 1, 6), then we have to find point B of the line segment AB -

As we know that-

If a line segment AB is with endpoints ( [tex]x_{1}, y_{1}[/tex] ) and  ( [tex]x_{2}, y_{2}[/tex] )then the mid points M are-  

M = ( [tex]\frac{ x_{1} + x_{2} }{2}[/tex] , [tex]\frac{ y_{1}  + y_{2}}{2}[/tex]   )

Here,

Let A ( - 1, 6 ), B ( x, y ) with midpoint M ( 4, 2 ) -

then by the midpoint formula M are-

( 4, 2 )  = ( [tex]\frac{ - 1 + x}{ 2}[/tex] ,  [tex]\frac{ 6 + y}{2}[/tex] )

On comparing x coordinate and y coordinate -

We get,

( [tex]\frac{ -1 + x}{2}[/tex] = 4 , [tex]\frac{ 6 + y}{2}[/tex]  =  2)

( - 1 + x = 8,  6 + y = 4)

( x = 8 + 1, y = 4 - 6 )

( x = 9, y = -2 )

Hence the required points  A are ( 9, - 2 ).

We can also verify by putting these points into Midpoint formula.

Answer:

GCF = 5

Step-by-step explanation:

Given:

The numbers are given as:

10, 30 and 45

A factor of a number is a number by which the given number is evenly divisible.

Example: 2 is a factor of 4 as [tex]4\div 2 =2[/tex]. So, 4 is evenly divisible by 2 and hence 2 is a factor of 4.

Now, factors of 10 = 1, 2, 5, 10.

Factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30.

Factors of 45 = 1, 3, 5, 9, 15, 45.

So, the greatest common factor in all the three numbers is 5.

Hence, the greatest common factor of 10, 30 and 45 is 5.

Answer:

[tex]x=-\frac{261}{46}[/tex]

Step-by-step explanation:

we have the expression

[tex]\frac{3x+2y-5z}{y-4z}=\frac{x}{3y}[/tex]

we have

[tex]y=6,z=-\frac{1}{2}[/tex]

To find the value of x, substitute the given values of y and z in the expression

[tex]\frac{3x+2(6)-5(-\frac{1}{2})}{6-4(-\frac{1}{2})}=\frac{x}{3(6)}[/tex]

solve for x

[tex]\frac{3x+12+\frac{5}{2}}{6+2}=\frac{x}{18}[/tex]

[tex]\frac{3x+12+\frac{5}{2}}{8}=\frac{x}{18}[/tex]

Multiplying in cross

[tex](3x+12+\frac{5}{2})18=8x[/tex]

[tex]54x+216+45=8x[/tex]

[tex]54x-8x=-216-45[/tex]

[tex]46x=-261[/tex]

[tex]x=-\frac{261}{46}[/tex]
