What is decimal ?The full number and the fraction are expressed simultaneously using decimals. By adding a "." (known as a decimal point) in this instance, we will divide the whole number from the fraction. Think about taking an ice cream cone as an illustration. Your purchase of ice cream will cost $2 and 50 cents, the dealer informs you. Currently, you would state that the ice cream cone costs $2.50 if you were to describe this amount in a single number. You may be utilizing decimals unknowingly in a variety of these real-world situations.

If rocks along the furnace creek fault have been offset 30 miles over 10 million years, what is the rate of plate motion in cm/year. (Hint: Rate x Time = Distance, and there are 5280 feet in one mile, and 2.54 cm. in one inch.)
Answers
The rate of plate motion in cm/year is equal to 3.3528 × 10⁻³ cm/year.
What is a conversion factor?A conversion factor can be defined as a number that is typically used to convert (change) a number in one (1) set of units to another, either by dividing or multiplying.
Generally speaking, an appropriate conversion factor to an equal value must be used when it is necessary to perform any mathematical conversion.
Conversion:
1 mile = 5280 feet
30 miles = X feet
Cross-multiplying, we have:
X = 30 × 5280
X = 158,400 feet.
Next, we would convert the value in feet to inch and then to cm as follows:
Distance = 158,400/12 = 13,200 inches.
In centimeters (cm), we have:
1 inch = 2.54 cm
13,200 inches = Y cm
Cross-multiplying, we have:
Distance, Y = 13,200 × 2.54
Distance, Y = 33,528 cm.
Now, we can determine the rate of plate motion in cm/year:
Rate = Distance/Time
Rate = 33,528/10,000,000
Rate = 3.3528 × 10⁻³ cm/year.

What is a Set's Cardinal Number?In a finite set, the number of distinct elements is known as the cardinal number. It is written as n(A) and can be read as "the number of set elements."
Let's assume,
U is the set of patients who reported at the hospital on that day.
F is the set of patients who complained of fever.
S is the set of patients who had stomach troubles.
I is the set of injured patients.
The given data can be written as follows:
n(U) = n(F∪S∪I) = 100
n(F) = 70
n(S) = 50
n(I) = 30
n(F∩S) + n(S∩I) + n(I∩F) - 3×n(F∩S∩I) = 44
Using the cardinal number of the union of three sets formula, we get
n(F∪S∪I) = n(F) + n(S) + n(I) - n(F∩S) - n(S∩I) - n(I∩F) + n(F∩S∩I)
100 = 70 + 50 + 30 - (44 + 3×n(F∩S∩I)) + n(F∩S∩I)
100 = 150 - 44 - 2×n(F∩S∩I)
2×n(F∩S∩I) = 106 - 100 = 6
n(F∩S∩I) = 3
Therefore, 3 patients had all the complaints.

Answers
The value of x is 8 cm.
What is the area of a rectangle?The area of a rectangle is the space occupied by the rectangle inside its perimeter. A rectangle's area is calculated by multiplying its length by its width.
Given:
Length of rectangle = 20 cm
Width of rectangle= x cm
Area of rectangle = length × width
= 20x cm²
The dimensions of the smaller rectangle cut out of it are,
Length = 16cm
Width = x-3
Area of the smaller rectangle = length × width
= 16(x - 3) cm²
The area of the shaded portion will be equal to the difference between both areas which is given as 80 square centimeters.
20x - 16(x-3) = 80
Now, we need to solve this equation to obtain the value of x.
20x - 16x + 48 = 80
4x = 80 - 48
4x = 32
x = 32/4
x = 8
Therefore, the value of x is 8 cm.

A vehicle factory manufactures cars. The unit cost C (the cost in dollars to make each car) depends on the number of cars made. If x cars are made, then the unit cost is given by the function C(x)=0.4x^2 - 104x + 13,586. How many cars must be made to minimize the unit cost? Do not round the answer
Answers
Answer:
130 cars
Step-by-step explanation:
You want the value of x (the number of cars made) that minimizes the unit cost, given by C(x) = 0.4x² -104x +13586.
VertexThe minimum cost will be found at the vertex of this quadratic cost function. For quadratic ax²+bx+c, the vertex is found at x=-b/(2a).
The cost function has a=0.4 and b=-104, so the number of cars that must be made to minimize the unit cost is ...
x = -b/(2a) = -(-104)/(2(0.4)) = 104/0.8
x = 130
130 cars must be made to minimize the unit cost.
__
Additional comment
A graphing calculator can plot the cost function and show you the coordinates of the minimum cost. The attachment shows the minimum cost per car is $6826 when 130 cars are made.

Which inequality is represented by the number line below?

An inequality which is represented by the number line above is: x < -7.
What is a number line?A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.
The rules for writing an inequality.In Mathematics, there are four (4) rules that are generally used to write an inequality and these include the following:
The circle/dot on a number line should be filled when the inequality symbol is (≥ or ≤).The circle/dot on a number line should not be filled when the inequality symbol is (> or <).When the arrow points to the left on a number line, the inequality is either (≤ or <).When the arrow points to the right on a number line, the inequality is either (≥ or >).Next, we would apply the aforementioned rules to write the solution to the inequality shown in the number line above:

Write a quadratic function for the following characteristics
Answers
Answer:
[tex]y=x^2+6x-16[/tex]
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{6 cm}\underline{Intercept form of a quadratic equation}\\\\$y=a(x-p)(x-q)$\\\\where:\\ \phantom{ww}$\bullet$ $p$ and $q$ are the $x$-intercepts. \\ \phantom{ww}$\bullet$ $a$ is some constant.\\\end{minipage}}[/tex]
Given points on the curve:
(-8, 0)(-6, -16)(2, 0)The x-intercepts of a quadratic function are the points at which the line crosses the x-axis, so when y = 0.
Therefore, the x-intercepts of the given function are -8 and 2.
Substitute these into the intercept formula:
[tex]\implies y=a(x-(-8))(x-2)[/tex]
[tex]\implies y=a(x+8)(x-2)[/tex]
Substitute the other given point (-6, -16) into the equation and solve for a:
[tex]\begin{aligned} y&=a(x+8)(x-2)\\\textsf{When }(-6,-16)\implies -16&=a(-6+8)(-6-2)\\-16&=a(2)(-8)\\-16&=-16a\\\implies a&=1\end{aligned}[/tex]
Therefore, the equation of the function in intercept form is:
[tex]y=(x+8)(x-2)[/tex]
Expand to standard form:
[tex]\implies y=x(x-2)+8(x-2)[/tex]
[tex]\implies y=x^2-2x+8x-16[/tex]
[tex]\implies y=x^2+6x-16[/tex]
Therefore, the quadratic function in standard form is:

Miss Jones mowed 1/4 of her lawn her son mowed 2/5 of it. who mowed most of the lawn? how much of the lawn still needs to be mowed
Answers
The son mowed most of the lawn
7/20 of the lawn still needs to be mowed
Explanations:Size of the lawn mowed by Miss Jones = 1/4
Size of the lawn mowed by her son = 2/5
To know who mowed the most lawn, find the LCM of the denominators
The LCM of 4and 5 = 20
Make the denominators of both fractions to be 20
Size of the lawn mowed by Miss Jones = 1/4 x 5/5 = 5/20
Size of the lawn mowed by her son = 2/5 x 4/4 = 8/20
Since 8/20 > 5/20, Miss Jone's son mowed more part of the lawn than Miss Jone
How much of the lawn still needs to be mowed:
