The formula for the remaining volume of fuel in a cars tank is I - E • D, where I is the initial volume of fuel, E if the fuel efficiency, and D is the distance traveled. Carson drove a distance of 120 kilometres. He initially had 30 litres of fuel, and his car's fuel efficiency is 100 cubic centimetres per kilometer. What calculation will give us the estimated volume of fuel left in Carson's tank by the end of the drive, in litres? a)30-100/1000 • 120 b)30•1000-100•20 c)30/1000 -100•120 d)30-100•1000•120
Answers
Answer:
a)30-100/1000 • 120
Step-by-step explanation:
Given:
Remaining volume of fuel in a cars tank = I - E • D
where,
I = initial volume of fuel
E = fuel efficiency
D = distance traveled.
Carson
I = 30
E = 100
D = 120
Estimated volume of fuel in Carson's tank = I - E • D
= 30 - 100/1000 * 120
a)30-100/1000 • 120
Answer:
A (30-(100/1000)x120)
Step-by-step explanation:
I is a volume quantity, D is a distance quantity, and E is a rate measured as volume/distance.
So ExD gives us volume quantity.
Distance units are consistent (kilometers) but the volume units of E are inconsistent with those of I and the desired answer.
Let's convert E to liters per kilometer. We will use the fact that there are 1000 cubic centimeters per liter.
You get: 30 liter - 100/1000 liters/kilometer x 120 kilometers
In conclusion, this is the calculation that will give us the estimated volume of fuel that remains in Carson's tank by the end of the drive, in liters:
30-100/1000x120.

how can you solve quadratic equation in one variable using factoring method?
Answers
If there exists a sum of two numbers that equal b, whose addends produce a product that equals c, you can rewrite the quadratic as a product of two binomials.
For example, take .
When thought through thoroughly, -5 has addends -2 and -3 that produce 6 when multiplied.
Thus, we can rewrite the quadratic as.
I hope this helps! You can ask for clarifications if needed. :)
The steps are;
look for two numbers such that if added will give the coefficient of x and if multiplied will give the product of the constant and the coefficient of x²Factor the common value from both brackets and get the required variableLet us assume the quadratic equation x² - 2x + 1 = 0
To solve this by factoring;
Step 1: We will first look for two numbers such that if added will give the coefficient of x and if multiplied will give the product of the constant andthe coefficient of x²
For the given equation, the two values are -1 and -1
The quadratic equation becomes;
x² - 1x - 1x + 1 = 0
x² - x - x + 1 = 0
(x²-x)-1(x-1) = 0
Step 2: Factorize the common value from both brackets
x(x-1)-1(x-1) = 0
x-1 = 0 and x - 1 = 0
x = 1twice
The given steps are the ways you can solve quadratic equations in one variable using factoring method

Find a value for k such that the following trinomial can be factored x^2-8x+k
Answers
Answer:
16
Step-by-step explanation:
x^2-8x+k is a quadratic expression of the form ax^2 + bx + c. Here a = 1, b = -8 and c = k. Focus on x^2-8x and complete the square as follows: Take half of the coefficient of x (that is, take half of -8) and square the result:
(-4)^2 = 16; if we now write x^2-8x+ 16, we'll have the square of (x - 4): (x -4)^2.
Thus, k = 16 turns x^2-8x+k into a perfect square.

Imani is making costumes for a play. She spent $146.58 on 21 yards of fabric. Write and solve an equation to find how much Imani paid for each yard of fabric.
Multiple choice question.
A)
21p=146.58; $6.98 per yard
B)
146.58p=21; $0.14 per yard
C)
146.58(21)=p; $3078.18 per yard
D)
21p=146.58; $3078.18 per yard
Answers
Answer:
A
Step-by-step explanation:
21 yards and Total cost of $146.58
p = 1 yard
Equation: 21p = 146.58
p = 146.58/21
p = 6.98
21p=146.58 will describe the equation and the amount paid for each yard is $6.98 so option (A) will be correct.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Amount of fabric = 21 yards
Since cost per yard of fabric is given by p
So,
The total cost of fabric = Amount of fabric × cost per yard
146.58 = 21p
21p=146.58
Now,
p = 146.58/21 = 6.98.
Hence "21p=146.58 will describe the equation and the amount paid for each yard is $6.98".

Because the vertical line did intercepted the vertical line exactly twice, the graph is a function and relation.
Because the vertical line intercepted the graph exactly twice, the graph is a function.
Answers
Answer:
The correct option is;
Because the vertical line intercepted the graph more than once, the graph is of a relation, but it is not a function
Step-by-step explanation:
Given that a function maps a given value of the input variable, to the output variable, we have that a relation that has two values of the dependent variable, for a given dependent variable is not a function
Therefore, a graph in which at one given value of the input variable, x, there are two values of the output variable y is not a graph of a function
With the vertical line test, if a vertical line drawn at any suitable location on the graph, intercepts the graph at more than two points, then the relationship shown on the graph is not a function.
