Step-by-step explanation:
Amanda pours 3/4 of her water into Barbara’s empty bottle. Barbara then pours 3/5 of her water into Charlie’s empty bottle. Charlie then pours 1/2 of his water into David’s empty bottle. If David now has 18 ounces of water, how many ounces does Amanda still have?
Answer:
20 ounces of water
Step-by-step explanation:
Work backwards. David has 18 ounces, which is half of Charlie's. So, Charlie had 18•2=36 ounces. That was 3/5 of Barbara's water, so Barbara had 60 ounces. That is 3/4 of Amanda's water, so Amanda had 80 ounces. To find how much Amanda had left subtract 60 from 80 to get 20.

Katelyn drove 210 miles in 3 hours. Samantha
drove 540 miles in 8 hours,
Who drove faster? Explain your answer.
please help it’s for 21 points
Answer:
katelyn
Step-by-step explanation:
you divide distance by time to get rate, and katelyn has a faster rate because 210/3 is more than 540/8
Answer:
Katelyn drove faster
t=d/s
s=d/t
d=s*t
Step-by-step explanation:
s=d/t is what we are using to find the speed
Katelyn- 210/3=70
Samantha-540/8=67.5
70>67.5
Katelyn drove faster
What will be the new position of the given point (–2, –3) after reflection across the x-axis?
a) (2, 3)
b) (-3, -2)
c) (-2, 3)
d) (3, -2)
Answer:
(2,3)
Step-by-step explanation:
The new position of the point (–2, –3) after reflection across the x-axis is (-2,3)
How to determine the new position?The point is given as:
(-2,-3)
The rule of reflection across the x-axis is:
(x,y) -> (x,-y)
So, we have:
(-2,-3) -> (-2,3)
Hence, the new position of the point (–2, –3) after reflection across the x-axis is (-2,3)

c+11=24
please help!!
Answer:
13
Step-by-step explanation:
Answer:
c=13
Step-by-step explanation:
Hey There!
c+11=24
When looking at this problem you want to get the variable on one side (c) and the constant on the other ( any whole number)
as you can see we need to get rid of the 11 on the left side
to do that we subtract 11 but whatever you do to one side you have to do to the other side
11-11 cancels out
24-11=13
so we can conclude that
c=13

Answer:
Vertex: (-1, 4)
Maximum: f(-1) = 4
Increasing: (-∞, -1)
Decreasing: (-1, ∞)
Step-by-step explanation:
The equation can be written in vertex form by "completing the square."
First factor out the leading coefficient from the x-terms.
f(x) = -(x² +2x) +3
Then add the square of half the x-coefficient inside parentheses. Add the opposite of that amount outside parentheses.
f(x) = -(x² +2x +1) +3 +1
Write in vertex form.
f(x) = -(x +1)² +4 . . . . . . . compare to a(x -h)² +k
You can see that the vertex is (h, k) = (-1, 4), and that the vertical scale factor 'a' is negative. This means the vertex is the maximum and the parabola opens downward.
The function will be increasing to the left of the maximum, decreasing to its right.

Vertex: (-1, 4)
Maximum: f(-1) = 4
Increasing: (-∞, -1)

1) 100N 2) 0.3m/s² 3) 1/2 kg
Step-by-step explanation:
1) F = ma
F = 50×2
F = 100N
2) F = ma
9000 = 30000×a
(9000÷30000) = a
a = 0.3m/s²
3) F = ma
1 = m×2
(1÷2) = m
m = 1/2 kg

7. The daily cost of production in a video game factory is calculated using c(x) = 400 + 25x, where x is
the number of complete video games manufactured. Which set of numbers best defines the domain of c(x)?
(1) integers
(2)positive real numbers
(3) positive rational numbers
(4)whole numbers
Answer:
(4) whole numbersStep-by-step explanation:
Given function:
c(x) = 400 + 25xwhere x is the number of complete video games.The complete video games can be expressed as positive integers or whole numbers, so the domain is whole numbers.
Correct choice is (4)
Answer:
Whole Number
Explanation:
Domain : The set of all the input values (i.e. the value of x ) in the function is called domain
The daily cost of production in a video game factory is calculated using c(x) = 400 + 25x
Cost expression : C(x) = 400 + 25x
Cost expression : C(x) = 400 + 25x
As x defines the number of complete video, since number of video cannot be negative.
1) Integers : integers are the numbers which can be positive, negative or zero, but cannot be a fraction
As, number of videos cannot be negative
so, x cannot be any integers
So, Integers is not the domain
2) Positive real numbers : Real numbers are the numbers which include both rational and irrational numbers.
As the x represent the complete number of video games, thus, x cannot be irrational
Hence, Positive real numbers is not the domain
3) Positive Rational Number : a number is expressed in the form of p/q then it is a rational number
The number of videos are in the complete number, so a fraction cannot be a complete number, thus, rational number cannot be a domain.
4) Whole Number : Whole numbers include natural numbers that begin from 1 onwards
As Numbers of videos are the complete number, and they are always positive, which is the defination of whole number, Domain is whole number
