Answer:
1/30 of a ton of the rock was left at the construction site
Hope this helps :)
Explanation below.
Step-by-step explanation:
1. Make the same denominators to add them which is 6 (LCM).
1/3 + 1/2
2/3 + 3/6 = 5/6
2. Make the same denominator to subtract them since had to take back 4/5 of a ton. 30 would be the Least Common Multiple of 6 and 5.
5/6 - 4/5
25/30 - 24/30 = 1/30
Determine whether each list is a sequence or a series and finite or infinite. 1,2,4,8,16,32, . . . . . .
From the list of numbers presented:
12481632we can determine that this is a infinite serie.
What are sequences?A sequence is an order of elements that are governed by a pattern, that is, it has variations between each element that remain constant and allow us to determine values before or after the known elements.
A sequence maintains an order, and this numerical order can be finite or infinite, in the given case we have the following list:
1, 2, 4, 8, 16, 32
2ⁿ⁻¹2⁰ = 12¹ = 22² = 42³ = 82⁴ = 162⁵ = 322ⁿ⁻¹
In this series we have the initial value of the same, but we do not know the final value, although we know its behavior, we can say that this series has no end, it is an infinite serie.

The solution for the expression ((8p² - 2s³) / m ) + ((58p² - 2s³) / m) + ((58p² - 2s³) / ( m + 5)) is 196.72
Given,
The expression: ((8p² - 2s³) / m ) + ((58p² - 2s³) / m) + ((58p² - 2s³) / ( m + 5))
Where,
Value of p is given as 3

Value of m is given as 4
Then,
((8p² - 2s³) / m ) + ((58p² - 2s³) / m) + ((58p² - 2s³) / ( m + 5))
= (8 x 3² - 2 x 2³) / 4 + (58 x 3² - 2 x 2³) / 4 + (58 x 3² - 2 x 2³) / 4 + 5
= (8 x 9 - 2 x 8) / 4 + (58 x 9 - 2 x 8) / 4 + (58 x 9 - 2 x 8) / 9
= (72 - 16) / 4 + (522 - 16) / 4 + (522 - 16) / 9
= 56 / 4 + 506 / 4 + 506 / 9
= 14 + 126.5 + 56.22
= 196.22
Therefore, the solution for the expression ((8p² - 2s³) / m ) + ((58p² - 2s³) / m) + ((58p² - 2s³) / ( m + 5)) is 196.72

How do I find (rs)(4)=?
How do i also find (r/s)(3)=?
The functions are express as follows:
(rs)(4) = 8(r / s)(3) = 2How to solve composite functions?A composite functions is gotten from the combination of two or more functions.
Therefore,
(rs)(4) = r(4) × s(4)
r(x) = 2√x
s(x) = √x
Hence,
r(4) = 2√4 = 2 × 2 = 4
s(4) = √4 = 2
Therefore,
(rs)(4) = r(4) × s(4) = 4 × 2 = 8
(r / s) (3) = r(3) / s(3)
r(3) = 2√3
s(3) = √3
Hence,

Answer:
a = 71°
Step-by-step explanation:
This looks like a supplementary angle
109 + a = 180
-109 -109
a = 71°
I hope this helps!
Answer:
a = 71°
Step-by-step explanation:
Hello!
The sum of angles on a line is 180°. That means, 109° and a have to add up to 180°.
Angles that add up to 180° are called supplementary angles.
Solve for a180° - 109° = a71° = aa is 71°.
Answer each question to solve the equation. **Remember to state the units in your answer** Jennifer saved some money from her birthday. During the summer, she worked part time at McDonalds. She was paid $15 an hour. The equation 50+15h=1250 represents the amount of money she has. 1. What could the 1250 represent in this situation? A. The amount of money she had saved before B. The amount of money she had at the end of the summer C. The amount of money she earned per hour D. The amount of money she earned per week 2. George said that 10 could not be the solution to the equation. Explain why he is correct (Hint: put 10 in the place of h). 3. Find the solution to the equation. Show your work.
The 1250 represents option B in the situation, George is correct, the solution to the linear equation is h = 80$.
What is a linear equation?
A linear equation has only one or two variables. No variable in a linear equation is raised to a power greater than one or used as the denominator of a fraction. When two values satisfying a linear equation are found and shown, all of the points on a coordinate grid fall on the same line.
Given that,
Jennifer was paid $15 per hour.
Given equation is 50+15h=1250
1)Here 1250 represent B.
Her financial situation towards the end of the summer.
Because as mentioned in the equation 50+15h=1250
Here, 50 is the money already there with her, and 15h was the amount paid to her,
So, by adding those both the amount 1250 will be the amount with Jennifer at the end of the summer.
2)Given equation is 50+15h=1250
By putting 10 in place of h (h=10)
50+15(10)=1250,
50+150=1250,
200=1250$.
Since, LHS is not equal to RHS.
Therefore, George is correct, 10 could not be the solution to the linear equation.
3) Given equation 50+15h=1250
15h=1250-50,
15h=1200,
h=1200/15,
h=80$.
Therefore, the solution for the equation h is 80$.

the price of a scooter and a cycle are in the ratio 5:2 if the scooter costs ruppes 4,200 more than the cycle ,whats the price of the cycle
The price of the cycle is 2800 and the price of the scooter is 2800+ 4200=7000
Let the price of the cycle be x
Then the price of the scooter will become X + 4200
As the price of a scooter and the price of a cycle are in the ratio of 5:2
So, it can be written as
x+4200: x:: 5:2
which implies
x= 2a and x+4200= 5a
a= x/2 and x+4200/5
equating both the equations, we get
x/2=(x+4200)/5
in order to solve this linear equation, we need to move 2 from the left-hand side to the right-hand side which would result in the change of sign from division to multiplication and we need to move 5 from the right-hand side to the left-hand side which would result in the change of sign from division to multiplication
5x=2x+8400
3x= 8400
X= 8400/3
X= 2800
So, the price of the cycle is 2800 and the price of the scooter is 2800+ 4200=7000

What is the pitch when the wavelength is 5 feet? hertz
A) The type of variation between pitch and wavelength is an inverse variation. b) the pitch when the wavelength is 5 feet would be 132 hertz.
What is Inverse Variation?we know that the Inverse Variation is a relationship between two variables in which the product is a constant.
Let x be a pitch of a musical instrument
y be the wavelength
x*y=k
We need to find the value of k for x=220 hertz and y=3 ft
Then x*y=k
220*3=k
k=660
And for x=165 hertz , y=4 ft
x*y=k
165*4=660
k=660
A) Therefore, the type of variation between pitch and wavelength is an inverse variation.
B) the pitch when the wavelength is 5 feet;
x=?
y=5 ft
k=660
x*y=k
Then solve for x
x=k/y
x=660/5
x=132 hertz

2/3 unit down.
The equation for the vertical translation of y=f(x).2/3 unit down is y=f(x)-2/3.
Using equations of the form y=f(x), you may be able to modify the graph in various ways. For example, you can move the chart up, down, left, or right, flip it around the x or y-axis, or stretch or shrink it vertically or horizontally. Understanding these transformations makes it easy to graph different functions. Start with a "basic model" and apply a series of modifications to change it to the desired function.
A point on the graph of y=f(x) has the shape (x,f(x)).
The points on the graph of y=f(x)-2/3 are of the form (x,f(x)-2/3).
So, the graph for y=f(x) -2/3 is the same as the graph for y=f(x) shifted down by 2/3 units.
