As the amount of space a rhombus encloses in a two-dimensional space can be defined as its area, the ABCD rhombus's area is A = 12 d1 d2.
What precisely is a rhombus?A particular type of rhombus is a parallelogram. In a rhombus, the opposing sides or angles are parallel as well as equal. A rhombus also has sides that are each the same length, and its diagonals come together at right angles to make its shape. A diamonds or rhombus is also referred to as a "rhombus."
How come ABCD is a rhombus?The diagonal lines are parallel. A rhombus is what it is. The parallelogram is a rectangle, rhombus, and square since the diagonals are all congruent and perpendicular to one another. It is a rhombus, ABCD.
Rhombus Area Calculation Formulas
Diagonal Use, A = ½ x d1 x d2
A = b h using Base and Height
Trigonometry is used, A = b2 × Sin (a)
Where b = length of any side, h = height of rhombus, d1 = length of diagonal 1, d2 = length of diagonal 2, a = measure of any inner angle

left on together, the cold and hot water faucets of a certain bathtub take minutes to fill the tub. if it takes the hot water faucet minutes to fill the tub by itself, how long will it take the cold water faucet to fill the tub on its own?
The cold water faucet will fill the tub on its own in 5.6 minutes.
Let us assume the time taken by cold water faucet to fill the tub be x minutes. Now, the rate of hot water faucet to fill the tub = 1/14
Combined rate of filling by both faucets = 1/4
Rate of filling by hot water faucet + Rate of filling by cold water faucet = Rate of filling of tub by combination of two faucets
1/14 + 1/x = 1/4
1/x = 1/4 - 1/14
1/x = (14 - 4)/(4×14)
1/x = 10/56
x = 56/10
x = 5.6 minutes
Thus, cold water faucet will take 5.6 minutes.

The perimeter of a playing field is 302 yards. It’s length is 7 yards longer than three times its width. What is the area of the playing field?
The area of the field is 4140 square yards.
What is a rectangle?A rectangle is a quadrilateral with all four interior angles 90°.
Given that, the perimeter of the field is 302 yards.
Let the length and width of the field be l and w respectively.
Given that, the length is 7 yards longer than three times its width, therefore,
l = 7 + 3w
The perimeter of the field is given by:
2(l +w) =302
l + w = 151
w = 151 - l..........(1)
Substitute l = 7+3w into the above equation:
w = 151 - 7 - 3w
w + 3w = 144
4w = 144
w = 36
Substitute w = 36 into equation (1):
36 = 151 - l
l = 151 - 36
l = 115
The area of the field is:
l × w
115 × 36
=4140
Hence, the area of the field is 4140 square yards.

Question B: During what interval(s) of the domain is the baseball’s height staying the same?
(btw I have to write the question)
Step-by-step explanation:
what does it mean for an object to stay at the same height ?
come on, you cannot tell me you don't understand this.
it means that e.g. the object is at a certain height (e.g. 50 ft above the ground) at the beginning of a time interval. then 1 seconds later it is still at the same height. 1 seconds after that it is still at this height. and so on.
how do you think that shows on a chart that displays height on an up or down scale ? as a flat (horizontal) line.
the chart is simply a rough picture of what the object does in real life.
so, where do we have flat (horizontal) segments in the curve ?
between second 2 and second 6.
and then infinitely after second 12.
in interval notation
[2, 6] and [12, +infinity)
please note the round bracket on the infinity side. it means the indicated end of the interval is not included. that is, because infinity is just a concept and not a number. it can never be reached. and it is therefore not included in the interval itself.
FYI - the flat line between second 2 and second 6 is not possible in real life, unless it rolls on a flat surface or something is holding it steady in place for these 4 seconds.
but a flying ball can never have a pure flat curve regarding height. only when it comes at rest on the ground. gravity would not allow that. not even for a bullet shot by a gun.

There are 60 books that are either hardcover or softcover. The hardcover books each weigh 26 ounces. The softcover books each weigh 12 ounces. The books weigh 1,056 ounces in all
The number of hardcover books is 24 and the number of the softcover book is 36.
Here we have to find the number of hardcover and softcover.
Here it is given that 60 books are there.
Let x be the number of hardcovers, so the number of software books is 60- x.
The weight of each hardcover is 26 ounces and of softcover is 12 ounces.
The total weight is 1056 ounces.
So we get:
26x + ( 60 -x) 12 = 1056
26x - 12x + 720 = 1056
14x = 336
x = 24

An online furniture store sells chairs for $200 each and tables for $600 each. Every day, the store can ship no more than 40 pieces of furniture and must sell no less than $12000 worth of chairs and tables. If xx represents the number of tables sold and yy represents the number of chairs sold, write and solve a system of inequalities graphically and determine one possible solution.
If the minimum 30 chairs were sold , then the minimum number of Tables sold is 10.
Given as :
The cost of each chair = $ 200
The cost of each table = $ 600
The total number of furniture sold per day = 40
The minimum amount of selling per day = $ 12000
Let the total number of chair = C
The total number of table = T
So , according to question
C + T = 40 .......1
200 C + 600 T = 12000 .......2
Solving eq 1 and 2
200 C + 600 T = 12000
200 × ( C + T ) = 40 × 200
i.e 200 C + 200 T = 8000
or, ( 200 C + 600 T ) - ( 200 C + 200 T ) = 12,000 - 8000
Or, 400 T = 4000
i.e T = 10
Put The value of T in eq 2
So, 200 C + 600 × 10 = 12000
or , 200 C + 6000 = 12,000
Or, 200 C = 12000 - 6000
Or, 200 C = 6000
i.e C = 30
The number of chair sold is 30
If the number of chair sold is 10 ,
Then the min number of table sold = 200 × 30 + 600 T = 12000
i.e 600 T = 12000 - 6000
or, 600 T = 6000
∴ T = 10
I.e T = 10
Hence, if the minimum 30 chairs were sold , then the minimum number of Tables sold is 10 .

Is there a proportional relationship between the number of bushels of oranges collected and the number of acres harvested over the two days? Explain.
No, it is not proportional because both variables cannot be zero at the same time.
No, it is not proportional because all ratios between the number of bushels collected and the number of acres harvested are not equivalent.
Yes, it is proportional because the farmer collected 18 bushels for every 1 acre harvested.
Yes, it is proportional because the farmer collected 180 bushels for every 1 acre harvested.
Answer:
(d) Yes, it is proportional because the farmer collected 180 bushels for every 1 acre harvested.
Step-by-step explanation:
You want to know if the ratios 4 acres : 720 bushels and 7 acres : 1260 bushels represent a proportional relationship.
ProportionA relationship is proportional if the ratio of the dependent variable to the independent variable is a constant. We can check this for the numbers given:
(720 bu)/(4 ac) = 180 bu/ac
(1260 bu)/(7 ac) = 180 bu/ac
The ratios are the same, 180 bushels for each acre, so the relationship is proportional.

a. Write an equation in point-slope form that represents distance as a function of time.
b. interpret the slope and y-intercept
c. how far can you bike in 4 hours?
justify your answer
a. The equation in a point-slope form that represents distance as a function of time is (y - 6)= (1/5)(x - 30).
b. The slope and y-intercept are (1/5) and 0 respectively.
c. In 4 hours I can bike for 40 miles.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
We know the equation of a line in point-slope form is (y - y₁) = m(x - x₁).
Given, x represents time in minutes and y represents the distance in miles.
Let us take two ordered pairs (30, 6) and (40, 8).
Slope(m) = (y₂ - y₁)/(x₂ - x₁).
Slope(m) = (8 - 6)/(40 - 30).
Slope(m) = 2/10.
Slope(m) = 1/5.
∴ The equation of the line that represents distance as a function of time
is (y - 6)= (1/5)(x - 30).
Let y = mx + b.
6 = (1/5)30 + b.
6 = 6 + b.
b = 0.
So, y-intercept(b) = 0 and slope(m) is 1/5.
I can bike in 4 hours or (4×60) = 240 minutes is,
y = (1/5)(240) + 0.
y = 48 miles.

The likelihood that something will occur is the foundation of it. The justification for probability serves as the basic foundation for theoretical probability. A coin is tossed, for instance, and the theoretical likelihood of getting a head is 1 in 2.Zlower = X₁ - μ/σ = 120 - 100/15 = 1.33
the probability is compared as
Pr ( X ≥ 120 ) = Pr(X - 100/15 ≥ 120 - 100/15)
