Answer:
1/3 < 2/3
Step-by-step explanation:
1/3 compared to 4/6
Simplify 4/6 by dividing the top and bottom by 2
4/5 = 2/3
Since the denominators are the same we compare the numerators

Two workers finished a job in 12 days. How long would it take each worker to do the job by himself if one of the workers needs 10 more days to finish the job than the other worker?
Answer:
20 days
Step-by-step explanation:
t = time required by one worker to complete the job alone
(t+8) = time required by the other worker
So:
7.5/ t + 7.5/ (t + 8) = 1
Solve for t.
...
t = 12 days, the first guy working alone
The other worker would finish the job in 20 days.
Answer:
7 days and 17 days
Step-by-step explanation:
We can write an equation to solve this. An equation could be: ½x + ½y = 12. x - y = 10. Variables that solve this equation are x=7 and y=17. 7 + 17 = 24÷2 (since there are 2 workers) =12. Also, ½(7) + ½17 = 3.5 + 8.5 = 12. So, we know that the faster worker will take 7 days and the slower worker will take 17 days.

Answer:

Step-by-step explanation:
In order to find the the value of x, first we need to calculate the length of the perpendicular dropped from the right angle to the hypotenuse of the given triangle.
Therefore, by geometric mean property, we have:
[tex]l(perpendicular) \\ = \sqrt{9 \times (25 - 9)} \\ = \sqrt{9 \times 16} \\ = \sqrt{144} \\ l(perpendicular) = 12 \: units \\ \\ Now \: by \: Pythagoras \: Theorem:\\ {x}^{2} = {9}^{2} + {12}^{2} \\ {x}^{2} = 81 + 144 \\ {x}^{2} = 225 \\ x = \sqrt{225} \\ x = 15[/tex]

If f(x) = -15x + 3, then f^-1(x) =
Answer:
f^-1(x) is - (x -3)/15
Step-by-step explanation:
f(x) = -15x + 3
To find f^-1(x) equate f(x) to y
That's
y = f(x)
Which is
y = -15x + 3
Next interchange the terms x becomes y and y becomes x
That's
x = - 15y + 3
Make y the subject
We have
-15y = x - 3
Divide both sides by - 15
We get
y = x-3/-15
y = - x - 3/15
Therefore f^-1(x) is - (x -3)/15

30 POINTS!!! Heather is collecting dimes. She saves one dime on the first day, two dimes on second day, and three dimes on third day. If this pattern continues, hom much money will heather have saved at the end of 30 days? Please Explain!
Answer:
hope dis help ;_;
Step-by-step explanation:
It's easy to see the manual solution: 1(.1) + 2(.1) + 3(.1) +......+ 30(.1).
But nobody wants to do that repetitive computation. If we factor out the (.1),
we see (.1) * (1+2+3+4...+30). Still somewhat repetitive, but not bad for just 30.
We really need a formula for big numbers though. The short cut for adding a series
of numbers is to find the average of the first and last numbers and multiply by how
many there are in the list:
(first + last)(the quantity of numbers) / 2 = (1 + 30)(30) / 2 = 465
465(.1) = $46.50
The money that Heather will save at the end of 30 days will be 465.
What is arithmetic progression?
Arithmetic progression is a sequence of numbers with a common difference. It is given by,
aₙ = a₁ + (n - 1)d
Where,
aₙ = the nᵗʰ term in the sequence
d = common difference
a₁ = first term
Now,
We have,
Heather saves one dime on the first day, two dimes on the second day, and three dimes on the third day and continues for 30 days.
So,
Money saved on the first day = 1
And,
Money save on 30 day = 30
So,
Using the sum of Arithmetic progression formula,
Sₙ = n/2 [ a + l ]
where,
n = 30
a = first term = 1
l = last term = 30
Now,
Sₙ = n/2 [ a + l ]
Sₙ = 30/2 [ 1 + 30]
Sₙ =15 × 31
Sₙ = 465
So, money saved at the end of 30 days = 465
Hence we can say that the money that Heather will save at the end of 30 days will be 465.

Step-by-step explanation:
Given

Determine the common ratio
The common ratio of a sequence is determined by dividing a term by its immediate previous term;
Let the term be represented with [tex]T_1, T_2, T_3[/tex] and the common ratio with r
From the analysis above;
[tex]r = \frac{T_2}{T_1}\ or\ r = \frac{T_3}{T_2}[/tex]
Substitute -5 for [tex]T_1[/tex]; -20 for [tex]T_2[/tex]; -80 for [tex]T_3[/tex]
[tex]r = \frac{-20}{-5}\ or\ r = \frac{-80}{-20}[/tex]
[tex]r = 4\ or\ r = 4[/tex]
Both values of r are the same;
Hence, the common ratio of the sequence is 4

WILL GIVE BRAINLIEST AND 25 POINTS! Find the value of x and y, given the following matrix equation: x= y=
Answer:
x = ±6
y = 10
Step-by-step explanation:
Solve for the top part.
x² + -4 = 32
x² = 32 + 4
x² = 36
x = √36
x = ±6
Solve for bottom part.
y + y - 4 = y + 6
2y - 4 = y + 6
2y - y = 6 + 4
1y = 10
By solving the upper part and the lower part of the matrix equation, the value of x and y are:
[tex]\mathbf{x = \pm6}\\\\\mathbf{y = 10}[/tex]
The given matrix equation can be solved by taking the upperpart to create an equation to solve for x, and also taking the lower part to create an equation to solve for y.
Thus:[tex]x^2 + (-4) = 32[/tex] (upper part)
[tex]y + y - 4 = y + 6[/tex] (lower part)
Solve each of the equation in the matrix.
Solve the upper part for x:
[tex]x^2 + (-4) = 32\\\\x^2 - 4 = 32[/tex]
Add 4 to both sides[tex]x^2 - 4 + 4 = 32 + 4\\\\x^2 = 36[/tex]
Take the square of both sides[tex]x = \sqrt{36} \\\\\mathbf{x = \pm6}[/tex]
Solve the lower part for y:
[tex]y + y - 4 = y + 6\\\\[/tex]
Add like terms[tex]y + y - 4 = y + 6\\\\2y - 4 = y + 6\\\\2y - y = 4 + 6\\\\\mathbf{y = 10}[/tex]
Thus, by solving the upper part and the lower part of the matrix equation, the value of x and y are:
[tex]\mathbf{x = \pm6}\\\\\mathbf{y = 10}[/tex]

Consider the line - 8x-5y = -7.
What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Answer:
See below
Step-by-step explanation:
First, you need to find the slope of the given line. You can do this by rearranging the equation so that it is in slope-intercept form (y = mx + b).
-8x - 5y = -7
-5y = 8x - 7
y = -8/5x + 7/5
The slope of this line is -8/5.
The slope of a line that is perpendicular will be the negative reciprocal. You have to change the sign, and basically flip the numerator upside down. The slope of the perpendicular line will be 5/8
-8/5 = 8/5 = 5/8
The slope of a line that is parallel will be equal. This means that the slope will be -8/5.

Then 4x + 4y = 28
We know that x = 5 as above
So let's substitute it:
4x + 4y = 28
(4 × 5) + 4y = 28
20 + 4y = 28
Let's get the 20 to other side
20 - 20 + 4y = 28 - 20
4y = 8
y = 8 ÷ 4
y = 2
Hence we get these two solutions
