How far can a woman drive into the tiwnif she drives out at 40 miles per hour,return over the same rod at 30 miles per hour, and spends 8 hours away from home, including a 1 hour stop for luch
Given the time, the distance that the.womn drives will be 240 miles.
How to calculate the distance?From the information illustrated, the woman drives out at 40 miles per hour, return over the same road at 30 miles per hour, and spends 8 hours away from home.
It should be noted that the average speed will be illustrated as:
= (2 × r1 × r2) / +r1 + r2)
= (2 × 40 × 30) / (40 + 30)
= 240/7
Since she drive for 7 hours, the distance will be:
= 240/7 × 7
= 240 miles.

A function and its graph are given. Find the domain. (Enter your answer using interval notation.)
f(x) =
x − 3
x − 8
The domain for the rational function is the set of all real numbers except for 8, this is written as:
{x | x ∈ R, x≠8}
How to find the domain of the given function?
For any function f(x), the domain is the set of the possible inputs.
In this case, we have the rational function:
f(x) = (x - 3)/(x - 8)
Now, we start by assuming that the domain is the set of all real numbers, and then we remove all the problematic values.
Now, we can't divide by zero, so the value of x that makes the denominator zero needs to be removed, that is such:
x - 8 = 0
x = 8
So the domain is the set of all real numbers except for 8, this is written as:
{x | x ∈ R, x≠8}

So, 13 games were played each month, if each month had the same number of games.
What is division?Compared to multiplication, division is the opposite. If three groups of four add up to 12, then division of 12 into three groups of equal size yields four in each group. Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division. It is referred to as a method of division to divide anything. According to the degree of difficulty, there are three different sorts of division procedures. These include the bus stop approach, the chunking method, and the long division method. The chunking method is also known as division by repeated subtraction.
Given Data
A total of 117 football games in the season, and 33 were played at night.
The season was nine months long.
Each month same numbers of game were played.
So,
117 ÷ 9
13
So, 13 games were played each month, if each month had the same number of games.

Find the perimeter of hexagon ABCDEF plotted below.
The mass, m kilograms, of a horse is 429 kg, correct to the nearest kilogram.
Complete this statement about the value of m.
Answer:
400 < m< 430 kg
Step-by-step explanation:
the mass of horse is 429 kg
estimated to the nearest hundred is 400 kg
estimated to the nearest tens is 430 kg
thus the value of m mass lies between 400 to 430
therefore
400 < m< 430 kg
The answer is 400 < m< 430 kg
Jaya's monthly bank statement showed the following deposits and withdrawals:

If Jaya's balance in the account was $94.42 at the beginning of the month, what was the account balance at the end of the month?
If Jaya's balance in the account was $94.42 at the beginning of the month, then account balance at the end of the month is $69.04 .
In the question ,
it is given that Jaya's account balance at beginning of month was $94.42 ,
first transaction +$31.87 ,
means Jaya deposited $31.87
So Account balance = $94.42+$31.87 = $126.29
Second transaction -$34.19 ,
means Jaya withdraw $34.19
So Account balance = $126.29-$34.19 = $92.10
third transaction -$58.47 ,
means Jaya withdraw $58.47
So Account balance = $92.10-$58.47 = $33.63
fourth transaction +$48.57,
means Jaya deposited $48.57
So Account balance = $33.63+$48.57 = $82.20
fifth transaction -$13.16 ,
means Jaya withdraw $13.16
So Account balance = $82.20-$13.16 = $69.04
Therefore , if Jaya's balance in the account was $94.42 at the beginning of the month, then account balance at the end of the month is $69.04 .

What is basic algebra ?Algebra is a branch of mathematics that facilitates the description of problems or situations into mathematical statements. It involves variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division to generate a valid mathematical statement. All branches of mathematics, such as coordinate geometry, calculus, and trigonometry, employ algebra. An elementary algebraic formula is 2x + 4 = 8. Algebraic expressions serve as the mathematical statement when operations on variables and constants, such as addition, subtraction, multiplication, division, etc., are done.

The dilated polygon image is attached below under a dilation with a scale factor of 3 and center of dilation (0,0)
What exactly is a polygon?In geometry, a polygon is a two-dimensional closed shape with straight sides that is flat or plane. It doesn't have any curved edges. A polygon's sides are also known as its edges. The vertices (or corners) of a polygon are the points where two sides meet.
What is transformation and dilation?Transformation is the movement of a point from one location to another. Transformations include rotation, reflection, translation, and dilation.
Dilation is the process of increasing or decreasing the size of a figure by a factor k. If a point A(x, y) is dilated about the origin by a factor k, the new point is A' (kx, ky).
Assume the polygon has vertices at A(0, 0), B(3, 3) and C. (-3, 3). If the polygon is dilated by a factor of three with the center of dilation at (0, 0), the new vertices are as follows:

The right angled triangle has an area of 22.5 cm² X+1 X-3 help quick with no calcalator way or quadratic formula
Answer:
x = 8
Step-by-step explanation:
You want the value of x for a right triangle with side lengths (x+1) and (x-3) and an area of 22.5 cm².
Triangle areaThe area of a triangle is given by the formula ...
A = 1/2bh
Then the area of this triangle is ...
22.5 = 1/2(x -3)(x +1)
45 = x² -2x -3
48 = x(x -2) . . . . . . . add 3 and factor out x
We know that 48 can be factored as (8)(6). Comparing this to x(x-2), we see that x=8.

Additional comment
x could also be -6, but that would make the side lengths be negative. The only applicable solution for this geometry is x=8.

Answer:
a) x³, 1/x, x, sin(x)
Step-by-step explanation:
You want to know which list of functions has the same graph when reflected across both the y- and x-axes.
Odd functionReflection across the y-axis transforms the function to ...
f(x) ⇒ f(-x)
Reflection across the x-axis transforms the function to ...
f(x) ⇒ -f(x)
Hence, reflection across both axes transforms the function to ...
f(x) ⇒ -f(-x)
A function that has the characteristic that f(x) = -f(-x) is an odd function. Its graph is symmetrical about the origin. We can check to see if the functions of interest match this definition of an odd function:

A parking lot's length is 4 yards longer than its width. The dimensions of the parking lot are width=9 and length =12.
Given that,
A parking lot's length is 4 yards longer than its width.
We have to determine the parking lot's measurements if the area is 117 square yards.
Let us take the width as x and we get the length as x+4.
We can write as,
x(x+4)=117
x²+4x=117
x²+4x-117=0
x²+13x-9x-117=0
x(x+13)-9(x+13)=0

We know that
• The probability of a head is 1/2.
,• The probability of a tail is 1/2.
Notice that the number of times they flip a coin is 7. Since both probabilities are the same, we just have to multiply 1/2 seven times by itself.
[tex]P=(\frac{1}{2})^7[/tex]Now, we multiply the probability with 7 since there are 7 possibilities.
[tex]P=7\cdot(\frac{1}{2})^7=7(0.0078125)=0.0546\approx0.055[/tex]Then, we multiply by 100 to express it as a percentage.

-3x - 2y = 12 (Equation - 2)
This can be written in matrix form as shown:

We can use cross multiplication,

= 4 ≠ 0
So the system has a unique solution,
Then,
[tex]D_{1} = \left[\begin{array}{ccc}8&2\\12&-2\\\end{array}\right][/tex]
We can use cross multiplication,
[tex]D_{1} = (8)(-2)-(12)(2)\\D_{1} = -16-24\\D_{1} = -40[/tex]

We can use cross multiplication,
[tex]D_{2} = (12)(1)-(-3)(8)\\D_{2} = 12+24\\D_{2} = 36[/tex]
So, they can solve the X and Y values,
X = D1 / D
X = -40/4
X = -10
Y = D2 / D
Y = 36/4
Y = 9
