The inequality of p is p < 10
How to determine the inequality of pFrom the question, we have the following parameters that can be used in our computation:
Total amount = $140
Coupon = $20
Number of people = 12
The inequality of p is then represented as
p < (Total amount - Coupon)/Number of people
Substitute the known values in the above equation, so, we have the following representation
p < (140 -20)/12
Evaluate
p < 10
Hence, the inequality is p < 10

11. The equation 26.70=k6 shows that buying 6 bags of apples would cost $26.70. How
much would it be for one bag?
10) Using the equation 98.4 = (12.3)8, it costs $12.30 (cost per unit) per uniform.
11) Using the equation 26.70 = k6, the cost of one bag of apples (unit rate) is $4.45.
What is the unit rate?The unit rate is the quotient of the total cost divided by the number of items contained.
The unit rate is the same as the average or mean of a data set.
We describe the unit rate as the slope of a linear equation.
The unit rate shows the constant rate of change in an equation.
The total cost of 8 uniforms = 98.4 = (12.3)8
The cost per uniform = 12.30 (98.4/8)
The total cost of 6 bags of apples = 26.70
The cost per unit = 4.45 (26.70/6)
Thus, the unit rate or cost is also described as the variable unit cost.

Find the coordinates of P so that P partitions the segment AB in the ratio 3 to 1 if A(7, -4) and B(-5, 4). Show your work.
Answer: A partition of a line segment is a point that divides the segment into a certain ratio of segments. In this case, point P partitions the segment AB in the ratio 3 to 1.
To find the coordinates of point P, we can use the following method:
Let the point P be (x,y)
The ratio of the segments AP:BP is 3:1, so we can use the proportion: (AP)/(BP) = 3/(1+3) = 3/4
We can use the coordinates of points A and B to find the coordinates of point P. The x-coordinate of P is (3/4) times the difference in x-coordinates of A and B, plus the x-coordinate of A. And the y-coordinate of P is (3/4) times the difference in y-coordinates of A and B, plus the y-coordinate of A.
So, using the coordinates of A and B:
x = (3/4)(-5 - 7) + 7 = -4
y = (3/4)(4 - (-4)) -4 = 3
Therefore, the coordinates of point P are (-4,3)

a rectangular garden is 115 * 90 m.it has two roads, each 6 m wide, running in middle of it, one parallel to its length and other parallel to its breadth.find the cost of constructing the roads at $ 100 per m
Step-by-step explanation:
so, the first road is 115 m long, the second is 90 m long.
we should be finished, if we multiply each road length by $100, right ?
well, not quite.
because the 2 roads overlap. for this overlap area we don't need to pay twice.
we have the choice : to which of the 2 roads do we assign the overlap area ?
let's "give" it to the longer road.
so, the cost for the longer road is simply
115 × 100 = $11,500
the cost for the shorter road is then without the overlap area (6 meters : the width of the other road)
(90 - 6)×100 = 84×100 = $8,400
in total the costs are
$11,500 + $8,400 = $19,900

Answer:
Correct choices are:

Step-by-step explanation:
Best way to solve this problem is to plug in x and y values for each ordered pair and see if these values result in a consistent equation. It is impossible to solve the equation since there are two unknowns and only one equation
Here is each ordered pair and resulting y value when x value is plugged in
(-1, 2) ==> y = 2, x = -1
6 - 2(-1) = 6 + 2 = 8
This is not equal to the given value of y =2. So incorrect
(-1, 8)
We figured out from above that when x = -1, y = 8 so this is a correct choice
(-2, 6) ==> x = -2, y = 6
6 - 2(-2) = 6 + 4 = 10
Does not match y-value; incorrect
(1, 4) ==> x = 1, y = 4

The Chang family has been traveling for 18 hours, thus, t-value is 18.
How should t-test results be interpreted?A significant t-score, also known as a t-value, implies that the groups are distinct, whereas a small t-score suggests that the groups are similar. Degrees of freedom are the values in a study that are open to change and are crucial for determining the significance and reliability of the null hypothesis.
D(t) = 2,280 - 60t
D(t) = 1,200; find t.
D(t) = 2,280 - 60t
1200 = 2280 - 60t
From both sides of the equation, deduct 2280.
1200 - 2,280 = 2280 - 60t - 2,280
- 1080 = - 60t
multiplied by -60 on both sides

Two lines intersect at a location, creating an angle. An "angle" is the term used to describe the width of the "opening" between these two rays. Angles are frequently expressed in degrees and radians, a unit of circularity or rotation. We encounter angles frequently in life. Angles are used in the design of buildings, roadways, and sports venues by engineers and architects.
C,U and B are the angles and the c,u and b are the sides opposite to the angles C,U and B respectively.
Law of cosines:
c² = u² + b² - 2ub cos C
58²=78²+48² - 2(78)(48) cos C

The equation you provided is a linear equation that can be solved by isolating the variable y on one side of the equation. To find the solution for y, we need to follow these steps
First, we will simplify the equation by combining like terms: 2.8y + 0.2y = 5y – 14 + 6 3y = 5y – 8
Next, we need to get y alone on one side of the equation by subtracting 3y from both sides: 0 = 2y - 8
We will add 8 to both sides of the equation: 8 = 2y
Finally, we will divide both sides of the equation by 2 to find the solution for y: y = 4
So the solution for the linear equation 2.8y + 6 + 0.2y = 5y – 14 is y=4.

What element is equal to Avogadro's number?.
The numerical value of both the mole and Avagadro’s number is 6.022 x 10²³. That is why the mole is equal to Avogadro's number.

So, in 1 mol of helium, which has a mass of (very close to) 4 g, there is A
atoms; in 1 mol of sucrose, with a mass of 342 g, there are A molecules.

The solution for the given system of equations is (5.5, 4.333).The correct option is B
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line in point slope form can be also written as-
y - y1 =m (x - x1)
We have the following set of equations -
4x − 15y = −43
2x − 3y = −2
These are the equations of a straight line. Plotting the graphs and finding the point of intersection would give us the solution. It can be seen from the graph that the solution is given by coordinate - (5.5, 4.333).
Therefore, the solution for the system of equations is (5.5, 4.333).

Solve for x. Leave your answer in simplest radical form.
The value of x using Pythagoras theorem is x = √30.
The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Using Pythagoras theorem,
⇒ 5² + base² = 8²
⇒ 25 + base² = 64
⇒ base = √64 - 25
⇒ base = √39
In the other triangle,
x² + 3² = 39
⇒ x² = 39 - 9
⇒ x = √30
