The other Number is 187.

To find the other number, we can use the information provided in the problem.

Let's denote the smaller number as "x" and the other number as "y". According to the problem, the difference between the two numbers is 97. So, we can set up the following equation:

y - x = 97

We are also given that the smaller number is 90. We can substitute this value into the equation:

y - 90 = 97

To find the value of "y," we can add 90 to both sides of the equation:

y = 97 + 90

y = 187

Therefore, the other number is 187.

Answer:

The slope is going to be 5 and the y-intercept is going to be (0,9)

Step-by-step explanation:

What is an expression?

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.

The number before x in an expression is going to be the slope of the equation. and the number by itself is your y-intercept of the equation.

What is your y-intercept?

The y intercept is the point on which your line crosses on the y axis.

The line will cross on the number 9 which causes 9 to be the y-intercept.

The simplified form of the function is \(f(x) = \frac{x+3}{x}\)

Given the following function as shown:

\(f(x)=\frac{x^2-9}{x^2-3x}\)

This can be factorized as:

\(f(x)=\frac{x^2-3^2}{x(x-3)}\\f(x)= \frac{(x+3)(x-3)}{x(x-3)} \\\)

Cancel out the common terms:

\(f(x) = \frac{x+3}{x}\)

Hence the simplified form of the function is \(f(x) = \frac{x+3}{x}\)\

Hi Phoenix! :)

I'm much late lol.

Answer:

\(\boxed{ \cfrac{x + 3}{x}} \)

Step-by-step explanation:

Given:

\( \cfrac{x {}^{2} - 9}{x {}^{2} - 3x } \)

Solution:

[Here the best option is to factorise the expression.]

Rewrite the numerator of the expression as

\( \cfrac{x {}^{2} - 3 {}^{2} }{x {}^{2} - 3x} \)

It can be seen that the numerator is like an algebraic identity:

> a² - b² = (a+b)(a-b)

ATP, numerator : a = x² and b = 3²

Now in the denominator take x common:

(x-3) in the denominator and (x-3) in the numerator gets canceled.

Step-by-step explanation:

The temperature at the bottom of the mountain is 50.9 °C.

Let's work through the given information step by step to find the temperature at the bottom of the mountain.

The temperature in the hotel is 21 °C.

The temperature in the hotel is 26.7 °C warmer than at the top of the mountain.

Let's denote the temperature at the top of the mountain as T_top.

So, the temperature in the hotel can be expressed as T_top + 26.7 °C.

The temperature at the top of the mountain is 3.2 °C colder than at the bottom of the mountain.

Let's denote the temperature at the bottom of the mountain as T_bottom.

So, the temperature at the top of the mountain can be expressed as T_bottom - 3.2 °C.

Now, let's combine the information we have:

T_top + 26.7 °C = T_bottom - 3.2 °C

To find the temperature at the bottom of the mountain (T_bottom), we need to isolate it on one side of the equation. Let's do the calculations:

T_bottom = T_top + 26.7 °C + 3.2 °C

T_bottom = T_top + 29.9 °C

Since we know that the temperature in the hotel is 21 °C, we can substitute T_top with 21 °C:

T_bottom = 21 °C + 29.9 °C

T_bottom = 50.9 °C

Therefore, the temperature at the bottom of the mountain is 50.9 °C.

Answer:

Question 1: The appropriate measures of center for this data set would be (1) Mean and (2) Median. There is no mode in this data set as there are no repeating values.

Question 2: To find the standard deviation, we first need to find the mean:

Mean = (513 + 490 + 496 + 380 + 490 + 513 + 503 + 513 + 500 + 492) / 10 = 494.0

Next, we find the difference between each data point and the mean:

(513 - 494.0), (490 - 494.0), (496 - 494.0), (380 - 494.0), (490 - 494.0), (513 - 494.0), (503 - 494.0), (513 - 494.0), (500 - 494.0), (492 - 494.0)

19, -4, 2, -114, -4, 19, 9, 19, 6, -2

Then we square each difference:

361, 16, 4, 12996, 16, 361, 81, 361, 36, 4

The sum of these squared differences is:

361 + 16 + 4 + 12996 + 16 + 361 + 81 + 361 + 36 + 4 = 14136

To find the variance, we divide the sum of squared differences by the number of data points minus one:

Variance = 14136 / 9 = 1570.7

Finally, we find the standard deviation by taking the square root of the variance:

Standard deviation = √1570.7 ≈ 39.6 (rounded to the tenths place)

Answer:

• The age of a kitten and its weight

• Temperature and the sales of ice cream

• The number of notebooks bought and the total cost.

Explanation:

Two variables have a positive association when an increase in the values of one of the variables also leads to an increase in the value of the second variable.

From the given options, those with a positive association are explained below:

(a)The age of a kitten and its weight

The older a kitten gets, the more the weight of the kitten until it gets to adulthood.

(b)Temperature and the sales of ice cream

When the temperature increases, people tend to purchase more ice cream.

(c)The number of notebooks bought and the total cost.

• If 1 notebook costs $5, then:

• 2 notebooks will cost $10.

As the number of notebooks bought increases, the total cost also increases.

The length of the rectangle is twice its width. If its perimeter is 7 1/3 cm, its length will be 22/9 cm, and the width is 11/9 cm.

Let's assume the width of the rectangle is "b" cm.

According to the given information, the length of the rectangle is twice its width, so the length would be "2b" cm.

The formula for the perimeter of a rectangle is given by:

Perimeter = 2 * (length + width)

Substituting the given perimeter value, we have:

7 1/3 cm = 2 * (2b + b)

To simplify the calculation, let's convert 7 1/3 to an improper fraction:

7 1/3 = (3*7 + 1)/3 = 22/3

Rewriting the equation:

22/3 = 2 * (3b)

Simplifying further:

22/3 = 6b

To solve for "b," we can divide both sides by 6:

b = (22/3) / 6 = 22/18 = 11/9 cm

Therefore, the width of the rectangle is 11/9 cm.

To find the length, we can substitute the width back into the equation:

Length = 2b = 2 * (11/9) = 22/9 cm

So, the length of the rectangle is 22/9 cm, and the width is 11/9 cm.

The total path length covered in 5 second will be 69.45 meter.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is a train going at 70 km/h must reduce its speed to 30 km/h when passing over a bridge. It performs the operation in five seconds.

Using the first equation of motion -

v = u + at

(30 x 5/18) = (70 x 5/18) + 5a

(30 x 5/18) - (70 x 5/18)  = 5a

- (5/18) x 40 = 5a

- (200/18) = 5a

a = - (40/18)

a = - 2.22 m/s²

S = 19.44 x 5 + 0.5 x (- 2.22) x 25

S = 97.2 - 27.75

S = 69.45 meter

Therefore, the total path length covered in 5 second will be 69.45 meter.
