A container can hold 18 litres of liquid. If there 7 2/3 litres of watee was poured into it, how much more water is needed to fill that container?
Answer:
Step-by-step explanation:
1 full container = 18 Liters.
The amount in the container = 7 2/3
The amount left to go is 18 - 7 2/3
Now I don't know how you have been taught to do this, but I think the easiest way is to make 18 = 17 3/3 If you do that then the 5 will be subtracted from the 17 and the 2/3 will be subtracted from the 3/3
17 - 5 = 12
3/3 - 2/3 = 1/3
So the answer is 12 1/3

Find the mean of the data in the dot plot below
Answer:
5km
Step-by-step explanation:
Do not let the number line fool you, instead take the numbers from teh numberline. Because mean is the numebrs added up and divided by the number of numbers there are in the data. If we take 4+4 (two 4s on number lines) and add 7, we get 15 and because there are 3 numbers we divide by 3 to get 5km

how many times as large is 6*10^24 then 1*10^2 (please hurry)
Answer:
Step-by-step explanation:
Awkward phrasing. Try the question with simpler numbers: How many times as large is 8 than 4?
8 is two times as large as 4. How do you know? You know because 8 ÷ 4 = 2.
How many times as large is 6*10^24 than 1*10^2?
(6×10²⁴) ÷ (1×10²) = (6÷1 ) × (10²⁴÷10²)
6×10²⁴⁻² = 6×10²⁰
6×10²⁴ is 6×10²⁰ times as large as 1×10²
what is the equation of a line passing between the points below? (-3,1) (5,-7)
Answer:
Ax + Ay + 2A = 0 for any nonzero A, for example (A=1): x + y + 2 = 0
Step-by-step explanation:
The equation of a line is
Ax + By + C = 0
so we know that:
A*-3 + B*1 + C = 0
A*5 + B*-7 + C = 0
Let's subtract one from the other:
A*(-3 - 5) + B*(1 + -7) = 0
A*-8 + B*8 = 0
B*8 = A*8
B = A
Let's input B = A into the first two equations
A*-3 + A*1 + C = A*-2 + C = 0
A*5 + A*-7 + C = A*-2 + C = 0
checks out
C = 2A
So for any nonzero A the equation of
Ax + Ay + 2A = 0 produces a line passing between the points. Example would be
x + y + 2 = 0
This is a example ^^^

A CD usually sells for $13.00. If the CD is 30% off, and sales tax is 5%, what is the total price of the CD, including tax?
Answer:
$9.56
Step-by-step explanation:
$13.00 x .30 = 3.90
13.00 - 3.90 = $9.10 x .05 = 0.46
$9.10 + 0.46 = 9.56

Sam needs to build a fence around his pool. The pool and the sidewalk around it have a distance around of 200 feet, so the perimeter of the fence needs to be at least 200 feet. The length of the fence is five more than three times the width.
Answer:
52
Step-by-step explanation:
The dimension of the pool that Sam needs to build a fence is 23.75 ft and 76.25 ft.
What is a rectangle?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at mid-point.
Sam needs to build a fence around his pool.
The pool and the sidewalk around it have a distance of 200 feet, so the perimeter of the fence needs to be at least 200 feet.
The length of the fence is five more than three times the width. That is
L = 3W + 5
Then by the formula of the perimeter.
[tex]\rm P\ \ = 2(L+W)\\\\200 = 2(3W + 5 + W)\\\\100 = 4W + 5\\\\9\ 5 = 4W\\\\W \ = 23.75[/tex]
Then the length will be
L = 3(23.75) + 5
L = 71.25 + 5
L = 76.25 ft
Thus, the dimension of the pool that Sam needs to build a fence is 23.75 ft and 76.25 ft.

What are the zeros of the function f, where f(x)=6x^2-9x-6
Answer:
x=NEGATIVE 1/2, POSITIVE 2
Step-by-step explanation:
Just use math.waycom
The non-negative zero of the function f(x) is x = 2.
What are zeros of quadratic function?The zero of the function is where the y-value is zero. The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.
here, we have,
For a given function f(x), the "zeros" of the function are the values of x such that:
f(x) = 0
In this case, we have the function:
f(x) = 6*x^2 - 9*x - 6
If we want to find the zeros of this function, we need to solve:
f(x) = 0 = 6*x^2 - 9*x - 6
To solve this, we can use the Bhaskara's formula, which says that for a general quadratic equation:
0 = a*x^2 + b*x + c
The zeros are:
x = -b ±√b² - 4ac / 2a
In this case our equation is:
0 = 6*x^2 - 9*x - 6
then, in the above notation, we have:
a = 6
b = -9
c = -6
Replacing these in our general formula, we get:
x = 9±15 /12
Then we have two zeros:
x = (9 + 15)/12 = 24/12 = 2
x = (9 - 15)/12 = -6/12 = -1/2
But we want only the non-negative, so we can discard the second one.
Concluding, the non-negative zero of the function f(x) is x = 2.

Could someone please help?
Answer:
y = (4)(3)^x, with a = 4, b = 3
Step-by-step explanation:
y = ab^x
4 = ab^0 = a(1) = a
108 = 4b^3
108/4 = 27 = b^3
cube root of 27 = 3, so b = 3

Answer: Because if there are 2 minus signs next to each other, it is automatically a plus sign
Answer:
that's because a negative plus a negative equals a positive
Step-by-step explanation:
When you have two negative signs, one turns over, and they add together to make a positive. If you have a positive and a negative, there is one dash left over, and the answer is negative.
