Answer:
The value of k=13
Step-by-step explanation:
Given the equation
[tex]2\left(k\:-3\right)\:=\:k\:+7[/tex]
[tex]2k-6=k+7[/tex]
Add 6 to both sides
[tex]2k-6+6=k+7+6[/tex]
[tex]2k=k+13[/tex]
subtract k from both sides
[tex]2k-k=k+13-k[/tex]
[tex]k=13[/tex]
Therefore, the value of k=13

Answer:
y = 740x - 400
Step-by-step explanation:
You need to find what b(the y-intercept) is in the equation.
y = mx + b, where x is the time in hours and m is your slope
They told us the slope m(the rate of change), which is constant at 740 meters per hour. Think of a straight line with a positive slope. We just need to find b.
We know that when x = 1.5, y = 710 meters above sea level. Write this as (1.5, 710) and substitute in your equation to find b.
y = 740x + b
710 = 740(1.5) + b
710 = 1110 + b
-400 = b
Now put together the entire equation since you have all the info you need using the slope intercept form: y = mx + b
Therefore, y = 740x - 400

1. Which is greater 25% of 90 or 28% of 82.
Answer:
28% of 82
Step-by-step explanation:
25% of 90 is 22.5
28% of 82 is 22.96
It should be noted that 28% of 82 is greater than 25% of 90
The value of 25% of 90 will be:
= 25% × 90
= 25/100 × 90
= 0.25 × 90
= 22.5
The value of 28% of 82 will be:
= 28% × 82.
= 28/100 × 82
= 0.28 × 82
= 22.96
Therefore, we can see that 28% of 82 is greater than 25% of 90

the diagram shows a parallelogra,. 3x-15, 2x, 2x, 2x+24, work out x
Answer:
x = 39
Step-by-step explanation:
In a parallelogram the opposite angles are congruent, thus
3x - 15 = 2x + 24 ( subtract 2x from both sides )
x - 15 = 24 ( add 15 to both sides )
x = 39
Answer:
x = 39
Step-by-step explanation:
In a parallelogram, oppsite angles are the same (congruent).
Therefore:
3x- 15 is equal to 2x + 24
Which can be written as:
3x - 15 = 2x + 24
Now we can solve for x
3x - 15 = 2x + 24
3x - 2x - 15 = 24
x - 15 = 24
x = 24 + 15
So, x = 39
(OPTIONAL):
(You can find the vlaue of the angles by plugging in x = 39 into the equations for example, 3x - 15 becomes 3(39) - 15 ----> 117 - 15 ----> 102° . )

There are 33.8 fluid ounces in a liter. There are 128 fluid ounces in a gallon. About how many liters are in a gallon? 2 3 4 5 Is your estimate larger or smaller than the actual number of liters in a gallon? Explain how you know. HTML EditorKeyboard Shortcuts
Answer:
1 gallon = 3.7869 Liter (Approx)
Step-by-step explanation:
Given:
1 liter = 33.8 ounces
1 gallon = 128 ounces
Find:
How many liters are in a gallon
Computation:
1 ounces = [ 1 / 33.8 ] liter
1 gallon = 128 ounces
1 gallon = 128 [1 / 33.8]
1 gallon = 3.7869 Liter (Approx)

What is Average Rate of Change function?The average Rate of Change function is defined as the average rate at which one quantity is changing with respect to something else changing. In simple terms, an average rate of change function is a process that calculates the amount of change in one item divided by the corresponding amount of change in another.
Average rate of change of a function A = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
Given an exponential function, say f(x), such that f(0) = 1 and f(1) = 2.
A quadratic function, say g(x), such that g(0) = 0 and g(1) = 1.
The rate of change of a function f(x) over an interval a ≤ x ≤ b is given by
[tex]\frac{f(b)-f(a)}{b-a}[/tex].
Thus, the rate of change (growth rate) of the exponential function, f(x) over the interval 0 ≤ x ≤ 1 is given by
[tex]\frac{f(1)-f(0)}{1-0}[/tex] = [tex]\frac{2-1}{1}[/tex] = 1
Similarly, the rate of change (growth rate) of the quadratic function, g(x) over the interval 0 ≤ x ≤ 1 is given by
[tex]\frac{g(1)-g(0)}{1-0}[/tex] = [tex]\frac{1-0}{1}[/tex] = 1
Therefore, the exponential grows at the same rate as the quadratic in the interval 0 ≤ x ≤ 1.

Ohm's law states that if the resistance of the path of current between two points is constant, then the voltage difference V between the points and the current I flowing between the points, measured in amperes, satisfy the relationship V=cI, where c is a constant. Which best describes the relationship between the rate of change with respect to time t of the voltage and the rate of change with respect to time t of the current?
Answer:
[tex]\dfrac{dV}{dt}=c\dfrac{dI}{dt}[/tex]
Step-by-step explanation:
Ohm's law states that if the resistance of the path of current between two points is constant, then the voltage difference V between the points and the current I flowing between the points, measured in amperes, satisfy the relationship :
V = cI ....(1)
Where c is a constant
Differentiate equation (1) wrt t as follows :
[tex]\dfrac{dV}{dt}=\dfrac{d(cI)}{dt}\\\\\dfrac{dV}{dt}=c\dfrac{dI}{dt}[/tex]
Where dV/dt is the rate of change of voltage and dI/dt is the rate of change of current.

Will brought a tray with 42 veggie sticks home from his job as a caterer. He took 18 carrot sticks off the tray. Half of the remaining sticks are peppers, and the other half are celery. Which equation can we use to find the number of pepper sticks on the tray?
Answer:
The equation to find the number of pepper sticks is:
Number of pepper sticks = 1/2 (42 - 18)
The number of pepper sticks is 12
Step-by-step explanation:
Will brought a tray with 42 veggie sticks home from his job as a caterer. He took 18 carrot sticks off the tray. Which equation can we use to find the number of pepper sticks on the tray?
The total number of veggie sticks = 42
The number of carrots sticks = 18
Let that number of the remaining veggies be represented as: d
Hence,
42 = 18 + remainder
42 - 18 = x
24 = x
We are told that:
Half of the remaining sticks are peppers, and the other half are celery.
The equation to find the number of pepper sticks is
Number of pepper sticks= (x)/2 = (42 - 18)/2
x = 1/2(42 - 18)
x = 1/2(24)
x = 12 pepper sticks
Gina checked 20 markers. 7 of them were working. What percent of her markers were not working?
Answer:
65%
Step-by-step explanation:
HOPE THIS HELPS
PLZZ MARK BRAINLIEST
The percent of her markers that were not working is 65%
How to find how much percent 'a' is of 'b'?Suppose a number is 'a'
Suppose another number is 'b'
We want to know how much percent of 'b' is 'a'.
Then, it is calculated as:
[tex]\dfrac{a}{b} \times 100[/tex] (in percentage)
The number of her markers not working = Total number of markers - number of markers working = 20 - 7 = 13
Thus, the percent of her total markers the markers not working is:
[tex]\dfrac{13}{20} \times 100 = 65\%[/tex]
Second method:
Let us suppose that 'p' percent of her markers are not working, then, as 13 of her markers are not working, so they are equal, or:
[tex]\dfrac{20}{100} \times p = 13\\\\\dfrac{p}{5} = 13\\\\\text{Multiplying 5 on both the sides}\\p = 65 \text{\: \:(In percentage)}[/tex]
