Answer:
x = -1.8
Step-by-step explanation:
Given equation:
[tex]-\dfrac{2}{9} x = \dfrac{2}{5}[/tex]
Part I: Cancel the numerators in the equation (a/d = a/f ⇔ 1/d = 1/f)
[tex]\implies -\dfrac{2}{9} x = \dfrac{2}{5}[/tex]
[tex]\implies -\dfrac{1}{9} x = \dfrac{1}{5}[/tex]
Part II: Use cross multiplication (a/b = c/d ⇔ a × d = b × c) and simplify:
[tex]\implies -\dfrac{1}{9} x = \dfrac{1}{5}[/tex]
[tex]\implies -({x \times 5) = {1 \times 9}[/tex]
[tex]\implies -5x = 9[/tex]
Part III: Divide -5 to both sides of the equation:
[tex]\implies\dfrac{-5x }{-5} = \dfrac{9}{-5}[/tex]
[tex]\implies \boxed{x= \dfrac{9}{-5} = \dfrac{-9}{5} = -1.8}[/tex]
Therefore, the solution is [tex]x = -1.8[/tex].
Answer:
[tex] x = -\dfrac{9}{5} [/tex]
Step-by-step explanation:
[tex] -\dfrac{2}{9}x = \dfrac{2}{5} [/tex]
Multiply both sides by the reciprocal of -2/9 which is -9/2.
[tex] -\dfrac{9}{2} \times (-\dfrac{2}{9})x = -\dfrac{9}{2} \times \dfrac{2}{5} [/tex]
[tex] x = -\dfrac{18}{10} [/tex]
[tex] x = -\dfrac{9}{5} [/tex]
In how many ways can the word "calculus" be arrange so that two L's do not come together?
Count the total number of permutations of the word "calculus": there are 8 letters, hence 8! = 40,320 total permutations.
Count the number of permutations in which the two L's occur next to each other. Effectively we're now talking about words consisting of 7 letters, of which there are 7! = 5,040.
It follows that there are
8! - 7! = 35,280
words in which two L's do not appear next to each other.

Step-by-step explanation:
We know that sum of angles of a triangle are equal to 180⁰
Therefore
29⁰+68⁰+x⁰=180⁰
97⁰+x⁰=180⁰
x⁰=180-97=83⁰
Hence x=83⁰
Also Side Note: x⁰=y⁰=83⁰(reason=vertically opposite angles)

Step-by-step explanation:
It appears the shaded area of the rectangle is half of the rectangle's area. This means if we find the area of the rectangle and divide it by 2 we will know the area of the shaded portion.
The formula for the area of a rectangle is [tex]lw=A[/tex]
Where
l is the length (8 for this)
w is the width (6 for this)
A is the area
However, since we are finding half the area we will divide lw by 2
Sub the values into the formula
[tex]\frac{lw}{2} =A\\\frac{(8)(6)}{2} =A\\\frac{48}{2} =A\\24=A[/tex]
It is predicted that by 2050, there will be 10^10 people living on Earth. At that time, it is predicted there will be approximately 10^12 trees. How many trees will there be for each person?
Answer:
100 trees per person
Step-by-step explanation:
10^12 trees / 10^10 persons = 10^(12-10) = 10^2 trees/person
Answer:
Step-by-step explanation:
Givens
There are 10^12 trees
There are 10^10 people
Solution
Number of trees / person = Number of trees / Number of people = 10^12/10^10= 10^(12 - 10) = 10^2 = 100
There will be 100 trees / every person on the planet.
What are the roots of the quadratic equation below?
2x2 - 12x + 13 = 0
Answer:
D
Step-by-step explanation:
Quadratic formula: [tex]\frac{-b+-\sqrt{b^2-4ac} }{2a}[/tex]
[tex]2x^2- 12x + 13 = 0[/tex]
[tex]x=\frac{-(-12)+-\sqrt{(-12)^2-4(2)(13)} }{2(2)}[/tex]
[tex]x=\frac{12+-\sqrt{144-104} }{4}[/tex]
[tex]x=\frac{12+-\sqrt{40} }{4}[/tex]
[tex]x=\frac{12+-2\sqrt{10}}{4}[/tex]
[tex]x=\frac{6+-\sqrt{10}}{2}[/tex]

the figure is cut into 12 equal pieces. shade 2/3 of the figure
Answer:
So you shade 8 parts in and the remaining is 4 so that the other 1/3 of 2/3
Answer
so basically you're asking shade 2/3 out of 12 equal pieces
so lets do 12 divided by 3 witch is four
so there would be 3 parts that have 4 pieces, and 4 times two is eight, so shade in 8 pieces :0 :)
John is 23 years old and rents a car for 4 days, from Thursday through Sunday. The cost of the car rental is 27.99 with unlimited miles, but the cost of the rental is 42% higher on Saturday and Sunday. The company charges a $40 fee for renters younger than 25 . How much will it cost John to rent the car?
Answer:
109.99 $
Step-by-step explanation:
add or maybe multiply the numbers that have to do with money: 27.99 + 42 + 40
It will cost $107.74 for John to rent a car.
What is addition?Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.
Given:
John is 23 years old and rents a car for 4 days, from Thursday through Sunday.
The cost of the car rental is 27.99 with unlimited miles,
but the cost of the rental is 42% higher on Saturday and Sunday.
The company charges a $40 fee for renters younger than 25.
The total cost,
= 27.99 + 40 + 27.99 x 1.42
= $107.74
Therefore, the cost is $107.74.

Answer:
C (the bottom one)
Step-by-step explanation:
B (the top one) has roots/solutions — as in, it crosses the x-axis.

A box is 36 inches long 18 inches wide and 6 inches deep. How many cubic feet are in the box?
The amount of cubic feet in the box = volume = 2.25 cubic feet.
What is the Volume of a Box?Volume of a box is the amount of cubic feet in the box which is calculated as: V = (length)(width)(height).
Given the following:
Length = 36 inchesWidth = 18 inchesHeight = 6 inchesVolume = (36)(18)(6)
Volume = 3,888 cubic inches.
Convert to 3,888 cu. in. to cu. ft. [1 cu. ft. = 1728 cu. in.]
3,888/1728 = 2.25 cubic feet.

For the given data set 31, 32, 31, 34, 30, 30, 31, 31, 30, 31, median is the best measure of the center.
The given data set is 31, 32, 31, 34, 30, 30, 31, 31, 30, 31.
In this data set, the best measure of the center would likely be the median.
The data set is relatively small and seems to have a repeated value (30), which could potentially skew the mean.
The median, on the other hand, would provide a more representative measure of the central tendency as it is not affected by outliers or repeated values as much as the mean or mode.
Hence, median is the best measure of the center for the data set.

Leigh bought a conical candle wax mold. The height of the mold is 16.5 inches and the radius of the inside of the top of the conical
mold is 2.4 inches. She fills the mold completely with candle wax so that it is level with the top of the conical mold.
Using 3.14 for , approximately how much candle wax can the conical mold hold?
A. 41.45 cubic inches
B. 124.34 cubic inches
C. 99.48 cubic inches
D. 43.41 cubic inches
Answer:
Formula for volume of cone;
V = 1/3π[tex]r^{2}[/tex]h
Plug in what you know:-
V = 1/3π[tex]r^{2}[/tex]
will be
V = 1/3(3.14) · 2.4^2 · 16.5
Simplify and solve,
V = 1/3(3.14) · 5.76 · 16.5
V = 1.05 · 5.76 · 16.5
V = 6.05 · 16.5
V = 99.825, your answer is C; 99.48 cubic inches.
