Which is a terminating decimal?

The algebraic expression of the mathematical statement is given as "The sum of k and 8" is k + 8

The mathematical statement is given as:

The sum of k and 8

In algebraic expression, "Sum" means +

This means that, the interpretation of the question is that we add k and 8

So, we have the following algebraic representation:

The sum of k and 8 ⇒ k + 8

Remove the mathematical statement in the above algebraic representation

The drawing of rectangle that has diagonal twice as long as its width is attached with this.

The equation for the length of the rectangle is l = [tex]\sqrt{3} x[/tex]

Given,

Width of rectangle, w= x

Diagonal of rectangle, d = 2x

We have to find the equation for length of rectangle.

We know that d² = l² + w²

Here,

(2x)² = l² + x²

4x² = l² + x²

l² = 4x² – x²

l² = 3x²

l = [tex]\sqrt{3}[/tex]x

That is the equation for length of rectangle is l = [tex]\sqrt{3}[/tex]x

Lets take width of rectangle, x = 3

Diagonal of rectangle, d = 2 × 3 = 6

L = [tex]\sqrt{3}[/tex] × 3 = 5.20

Answer:

316 or -316.

Step-by-step explanation:

x^3 - y^3 = (x - y)(x^2 + xy + y^2)

               = 4(x^2 + y^2 + 21)

x - y = 4

xy = 21

Substitute x = 4 + y in the last equation

(4 + y) y = 21

y^2 + 4y - 21 = 0

(y + 7)(y - 3) = 0

y = 3, -7.

So, x = 7, - 3.

So,  x and y are 7 and 3 or -7 and -3.

But x^2 + y^2 = 9 + 49 = 58 whichever is true,

So, x^3 - y^3

= 4(x^2 + y^2 + 21)

= 4 (58 + 21)

= 316,

If x = -3 and y = -7 , then the answer is

-316.

The equation of the line in slope-intercept form is y = (-2)x + (-3)  .

The equation of a line in slope-intercept form can be written as follows,

y = mx + c                                                       equation 1

m in the above equation represents slope of the line and c represents the intercept.

The given equation is 3y + 9 = -6x .

To get the equation of the line in slope-intercept form we need to convert the given equation in the format of equation of a straight line i.e., equation1. So, now we will rearrange the given equation as

3y + 9 = -6x

3y = -6x - 9

On dividing both sides of above equation by 3, we will get

y = (-2)x + (-3)                                                 equation 2

On equating equation 1  and equation 2, we will get

Slope of the line = m = -2

Intercept = c = -3

The equation of the line in slope-intercept form is y = (-2)x + (-3)  .

Step-by-step explanation:

(x - 1)^2 =1/2 ( y - 5)

or

x^2 - 2x + 1 = y/2 - 5/2

2x^2 - 4x + 2 - y + 5 = 0

2x^2 - 4x - y + 7 = 0

The length of the third side of the right triangular flower bed is 10 feet.

A right-angled triangle is a triangle with one of its interior angles equal to 90°. The side opposite to the right angle is the largest side and is referred to as the hypotenuse. Hypotenuse is always greater than any of the other two sides.

If two of the sides of the flower bed are 7 feet long each, then these are the sides adjacent to the right angle. We are to find the length of the third side, which is the hypotenuse, using the Pythagorean theorem.

Pythagorean Theorem states that the square of the length of the hypotenuse of a right-angled triangle is equal to the sum of the squares of the two other sides.

c^2 = a^2 + b^2

where a and b are the adjacent sides to the right angle

c is the hypotenuse

c^2 = 7^2 + 7^2

c^2 = 49 + 49

c^2 = 94

c = 9.899

Hence, he length of the third side of the right-angled triangular flower bed is 10 feet.

After calling the parents, and explaining them the issue of smashed phone, they travelled at a speed of 2.223 m/s = 8.0028 km/hr

As per the question statement, we are given that we call our parents to explain our issue with having a smashed phone and your parents travel at 20000 meters in 2.5 hours. We are supposed to find out that how fast did the parents rush to get here. Basically we have to find their speed of travelling.

Before solving the question, we must be aware that what is speed.

[tex]speed = \frac{distance}{time}[/tex]

and distance and time should be in SI units.

Given distance = 20,000 meters

Given time = 2.5 hours

[tex]1 hour = 60 min\\2.5 hour = 2.5*60\\2.5 hour = 150 min[/tex]

[tex]1 min = 60 sec\\150 min = 150*60 sec\\150 min= 9000 sec[/tex]

Therefore given time = 9000 sec

Therefore speed = [tex]\frac{distance}{time} = \frac{20000}{9000}[/tex]

Speed= 2.223 m/sec

Hence they travelled at a speed of 2.223 meters per second

2.223 m/s = 8.0028 km/hr

The number of hours Aisha worked babysitting and landscaping last week is 7.9 hours and 9.9 hours respectively.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

We have been given that Aisha is working two summer jobs, making $7 per hour babysitting and $8 per hour landscaping

Let the number of hours babysitting would be x

And the number of hours landscaping would be y

Last week Aisha worked 2 more hours babysitting than hours landscaping and earned a total of $134.

y = x + 2

7x + 8y = 134

Substitute the value of y = x + 2 in the equation,

7x + 8(x + 2) = 134

7x + 8x + 16 = 134

15x = 134 - 16

15x = 118

x = 118/15

x = 7.9

Substitute the value of x = 7.9 in the equation y = x + 2 ,

y = 7.9 + 2

y = 9.9

Therefore, the number of hours Aisha worked babysitting and landscaping last week is 7.9 hours and 9.9 hours respectively

Answer:

(x,y)=(10,8)

Step-by-step explanation:

Let x be hours worked babysitting and y be hours worked landscaping.

We would have our first equation, 7x+8y=134.

Knowing that she worked 2 more hours babysitting than landscaping, we can determine and replace the x variable as: x=y+2

7(y+2)+8y=134

Use the distributive property to multiply 7 by y+2.

7y+14+8y=134

Combine 7y and 8y to get 15y.

15y+14=134

Subtract 14 from both sides.

15y=134−14

Subtract 14 from 134 to get 120.

15y=120

Divide both sides by 15.

y=120/15​

Divide 120 by 15 to get 8.

y=8

and since she worked 2 more hours babysitting, x=10.

Let's replace our values in the original equation:

7x+8y=134

7(10)+8(8)=134.

70+64=134.

Therefore, we can conclude that Aisha worked 10 hours babysitting and 8 hours landscaping last week.

Hope this helped!

Answer: 55 degrees

Step-by-step explanation:

a+90+35=180 ==> a straight line measures 180 degrees and the angles a, a right angle, and 35 lie on that line. A 180 degree angle is called a straight angle. Also, if there is a tiny box in between an angle, that means that the angle is a right angle.

a+125=180

a+125-125=180-125

a=180-125

-89 can be represented by using 8-bit two's compliment as 10100111.

Binary encoding can be defined as a standard technique that is designed and developed to convert data in plain text (source alphabets) to a form that is easily used by different operating systems (OS), especially through the use of a binary digit (bit) or two-symbol system.

In Computer programming, two's complement of base-10 is generally easier to implement because it has a single representation of 0 only.

First of all, we would determine the positive version of -89, which is 89:

2 | 89

2 | 44 R 1

2 | 22 R 0

2 | 11 R 0

2 | 5 R 1

2 | 2 R 1

2 | 1 R 0

2 | 0 R 1

Next, you would read the decimal number (base-2) upward and this gives:

89₂ = 01011001.

For the negative integer number representation on 8-bits, we would replace all the 0s with 1s and the 1s with 0s as follows:

01011001 = 10100110

For the 8-bit two's complement, we would add 1 to the above number:

-89 = 10100110 + 1

-89 = 10100111.

The required equation is 6x+7=331 and the no. of students traveling on each bus is 54.

A mathematical equation can be defined in a variety of ways. In its most basic form, an equation is a mathematical statement that shows that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. One or more variables are used in the most basic and simple algebraic equations in mathematics.

Given data:

Total no. of students: 331

Number of students on bus = 7

No. of buses = 6

Let the no. of the students on each bus be x.
