The difference in the temperature of Bombay to St. Petersburg is 28° C.

What is the difference between two numbers and how is it calculated?
An arithmetic operation called subtraction simulates the process of deleting items from a collection. The negative symbol, or, denotes subtraction. Subtraction is the process of subtracting a matrix, vector, or other quantity from another according to predetermined criteria in order to find the difference.
Subtracting two numbers from each other is a type of subtraction. The difference between two numbers is calculated by deducting the smaller of the two values from the larger.

Given, the temperature in St. Petersburg = T₁ = -11° C
The temperature in Bombay = T₂ = 17° C
Using general comparison, we get T₂>T₁, since one is positive and the other is negative.
Therefore following available literature,
Difference in temperature = T₂ - T₁ = 17 - (-11) = 17 + 11 = 28° C
Thus, the required difference in temperature of Bombay to St. Petersburg is 28° C.

Answer:

The last one

Step-by-step explanation:

this is really hard to read but you have to see which y values increase by a constant amount. Only the last case is linear in which each value increases by 3

There is a mistake in the first step. The correct way to add the linear expression is (−3.78b + 12) − (4.82b − 16) = -8.6b + 18

An expression is used to show the relationship between the variables.

The linear expression to add is as follows: (−3.78b + 12) − (4.82b − 16)

Firstly we open the bracket on the right side by multiplying the negative sign by the numbers in the brackets.

(−3.78b + 12) − (4.82b − 16)

−3.78b + 12 - 4.82b + 16

Combine like terms

−3.78b + 12 - 4.82b + 16

-3.78b - 4.82b + 12 + 16

Add the like terms

-3.78b - 4.82b + 12 + 16

-8.6b + 18

Therefore, she made the mistake in the first step.

Answer:

6.75

Step-by-step explanation:

Consider the ratio:

$4.50 : 6 apples

We need to multiply this ratio by a value such that the right side is 9 because there are 9 apples in array p. This value is 9/6 = 3/2.

$4.50 : 6 apples

× 3/2     × 3/2

$6.75 : 9 apples

So, the value of p, or 9 apples, is $6.75, which you will input as 6.75.

Answer:

24

Step-by-step explanation:

If the ratio of racers to divers is 6:2 then compare that to 18:x

6 times 3 is 18

2 times 3 is 6

x is 6

Now add 6 and 18

You get 24

The greatest common factor (GCF) of the given expression 48x^4 and 44x^5 is  4x^4.

Greatest common factor, as the name implies, is greatest among all common factors among the quantities given. We can factorize the quantities in smallest relative factors possible (one level of factors over which all quantities can form themselves), and collect as many common factors as we could. Those will together compose GCF(Greatest common factor).

To find the GCF of [tex]48x^4[/tex] and [tex]44x^5[/tex]. we have to write the prime factorization of both the terms;

Prime Factorization of   [tex]48x^4[/tex]= 2 × 2 × 2 × 2 × 2 × 2 × x × x × x× x

Prime factorization of  [tex]44x^5[/tex] = 2 × 2 × 11  × x × x × x × x × x

Thus the common factors are 2 × 2x × x × x× x

We need to use simple division to solve the problem. The number of cards each friend received is 11.

It is said that Landon has 56 cards, he kept 12 cards for himself, so we can subtract 12 cards from the whole lot to get the total number of cards he distributes among his friends.

56-12=44

There are 44 cards that he will distribute among his friends equally, we can get that by simply dividing the total number of cards by the number of friends which is 4.

number of cards for each friend=44/4=11

Answer:

Answer down below!

Step-by-step explanation:

Let's find a point on the graph that we can start off on

We can use (2,-1)

From there, we can use rise/run to find our answer

We go up 3 and over -2

So, our slope is -3/2 because we cannot simply it any further

The slope of the line is 2 for the equation that is perpendicular.

Slope of the line:

Slope of the line refers the change in y coordinate with respect to the change in x coordinate.

Given,

Here we have the equation 3x + 6y = - 72 that is perpendicular to the line.

Now, we need to find the slope of the line from it.

First we have to convert the given equation of line into standard form,

Then we get,

3x + 6y + 72 = 0

Now we know that the slope of the line for this type of equation is,

m = -a/b

Whlie we compare the equation with the standard form ax + by + c = 0,

Then we get the value of a = 3 and b = 6

Therefore, the slope of the line is

m1 = -3/6

m1 =-1/2

Here we need to find the slope of a line which is perpendicular to the given line.

Through the definition we know that product of two perpendicular line is -1.

So,

m1 x m2 = -1

(-1/2) x m2 = -1

m2 = 2

Therefore, the slope of perpendicular line is 2

The slope of line will be calculated using the formula :

Slope = [tex] \frac{y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

The first point is (-2, 7) and second point is (-9, 4). So, [tex] y_{2}[/tex] = 4, [tex] y_{1}[/tex] = 7, [tex] x_{2}[/tex] = -9 and [tex] x_{1}[/tex] = -2. Keep the values in formula to find the values of slope of the line.

Slope = (4 - 7)/(-9 - -2)

Performing subtraction in numerator and denominator

Slope = -3/-7

the dimensions of the box that minimize the amount of material used is 4.641cm by 4.641cm by 2.32cm

Let the side of the square base be x

h be the height of the box

Volume V = x²h

50 = x²h

h = 50/x² ..... 1

Surface area =  x² + 2xh + 2xh

Surface area S =  x² + 4xh  ...... 2

Substitute 1 into 2;

From 2; S =  x² + 4xh

S = x² + 4x(50/x²)

S = x² + 200/x

To minimize the amount of material used; dS/dx = 0

dS/dx = 2x - 200/x²

0 = 2x - 200/x²

0 = 2x³ - 200

2x³ = 200

x³ = 100

x = ∛100

x = 4.6416cm

Since V = x²h

50 = 4.642²h

h = 50/21.548

h = 2.32cm

Nathan's salary is $48 and Will's salary which three times of Nathan's salary is $144.

What is salary?

An employment contract may include a salary clause as a type of recurring payment from an employer to an employee. In contrast, piece wages are paid separately for each job, hour, or other unit rather than on a regular schedule. Salary can also be seen from the perspective of operating a corporation as the expense of obtaining and keeping employees to carry out operations; this is known as a personnel expense or salary expense. Payroll accounts are used in accounting to record salaries.

It is given in the question that Will's salary is three times Nathan's salary.

So, lets assume that Nathan's salary is X it implies that Will's salary will be 3 times X = 3X

Together they earn $ 192.

So,

X + 3X = 192

4X = 192

X = 192/4

X = 48

Therefore, Nathan's Salary is $48

Since, Will's salary is 3 times of Nathan's salary,

So,

Will's salary = 3 (48) = 144

Therefore, Will's Salary is $144

decimal form is 150.6

Step-by-step explanation:

a formula for the surface area of the box in terms of only x , the length of one side of the square base is A =  x² + 170368 cm³/x

The volume of the box with square base is V = x²h where x = length of side of square base and h = height of box.

Now, the area of the of box open at the top with dimensions of length, l , width, w and height, h are

A = 2lh + lw + 2wh

Now for a box of square base, l = w = x.

So, A = 2xh + x² + 2xh

A = x² + 4xh

Since V = x²h and V = 42592 cm³,

h = V/x² = 42592/x²

substituting h into A, we have

A =   x² + 4xh

A =  x² + 4x(42592 cm³/x²)

A =  x² + 4 × 42592 cm³/x

A =  x² + 170368 cm³/x

The square of any odd number is not always one more than a multiple of 8. The proposition is false.

Natural numbers can be divided into even numbers (i.e. 2, 4, 6) and odd numbers (i.e. 1, 3, 5). Let be n an element of the set of even numbers and the element 0, such that odd numbers are of the form:

x = 1 + n

Then,

(1 + n)²

1 + 2 · n + n²

If 1 + 2 · n + n² is one more than a multiple of 8, then we find the following relationship:

1 + 2 · n + n² = 8 · x + 1, where x is a natural number.

2 · n + n² = 8 · x

For x = 1:

2 · n + n² = 8

n² + 2 · n - 8 = 0

(n + 4) · (n - 2) = 0

Then, the least even number is 2 and the least odd number is 3. This implies that the proposition is not observed for (1 + n) = 1. Therefore, the proposition is false.
