The plane's average speed during the flight is 381.43 miles per hour.

The average speed is the quotient of the total distance covered during the flight divided by the total time used.

The Average Speed is the scalar quantity that shows the rate of change in displacement from one point to another.

The distance for the first miles = 1,295 miles

The time it took the plane to cover the distance = 3 hours 33 minutes

The distance for the last lap = 738 miles

The time it took the plane to cover the last distance = 1 hour 47 minutes

The total distance covered for the journey = 2,033 miles (1,295 + 738)

The total time for the journey = 5 hours 20 minutes or 5.33 hours

Average Speed = 2,033/5.33

= 381.43 miles per hour

Thus, the plane's average speed during the flight is 381.43 miles per hour.

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

a=55 degrees

Answer:

The next two terms is 144 and 169

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.

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 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.

Here we can conjecture that :

The measure of an exterior angle is equal to the sum of measures of its nonadjacent interior angles.

The exterior angle of any polygon is defined as the angle which is at the outside boundaries of that polygon. whereas, the interior angle is defined as the angle which is inside the polygon. In the other words if the polygon has the point within the angle it is in the interior of the angle , but if the point is outside then is it said to be in the exterior of the angle.

Non adjacent angles are those angles which are not adjacent to each other. The non adjacent angles follow one of the  properties which are listed below:

In the given question,

taking a example say a triangle ABC with  ∠A=64,  ∠B = 45 and an external angle x to the side AC.

as sum of angles equal to 180

thus,  ∠A +  ∠B +  ∠C = 180

         64 + 45 +  ∠C = 180

          ∠C = 180-109 = 71

now as x is external to  ∠C,

therefore x = 180 -  ∠C = 180 - 71

                x = 109 =  ∠A +  ∠B

Hence we can make the conjecture that, the measure of an exterior angle is equal to the sum of measures of its nonadjacent interior angles.

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)

The function that represents the Transformation of the graph is  F(X+1/2).

Different non-vertical lines have different slopes and/or y-intercepts. They are graphs of various linear functions. If there are two such lines, one can be considered a transformation of the other. There is a group of functions called the family, each function being a transformation of a special function called a parent. Linear functions form a series of functions. All linear functions are transformations of the function y = x. The function y = x is an upper linear function. Each family role is a transformation of a parent's role. The conversion type is translation. A translation moves the graph of the parent function horizontally, vertically, or both without changing shape or orientation. So, the function that represents this transformation is F(X+1/2).

-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.
