what does a rhombus look like
A rhombus with opposite sides are parallel and equal, and opposite angles are equal looks like Diamond.
A closed two-dimensional plane figure is a rhombus. It is regarded as a peculiar parallelogram, and due to its distinctive characteristics, it acquires a distinct identity as a quadrilateral. Due to its equal length sides, a rhombus is also known as an equilateral quadrilateral. The name "rhombus" is derived from the Greek word "rhombos," which really refers to a spinning object.
Due to the fact that it is a quadrilateral with two pairs of parallel sides, a rhombus can be considered a particular parallelogram. A rhombus also has equal sides on all four sides, exactly like a square. Because of this, it is often referred to as a tilted square. To comprehend the relationship between the rhombus shape, parallelogram, and square, look at the graphic below.

If y is inversely proportional
to x and y = 27 when x = 4,
find x when y = 8.
The value of x when y = 8 is 13.5
How to determine the value of xIf y is inversely proportional to x, it means that their product is a constant value.
We can represent this relationship using the formula:
y * x = k
where k is the constant of proportionality.
We are given that y = 27 when x = 4, so we can solve for k:
27 * 4 = k
This gives
k = 108
Now that we know the value of k, we can use it to find x when y = 8:
y * x = k
This guves
8 * x = 108
So, we have
x = 13.5
Hence, when y = 8, the value of x is 13.5.

5. A population of bumble bees starts at 20 bees in the spring. Every week, the
population of bumble bees triples. Write the geometric sequence formula and
find the number of bees after 32 weeks. Show all of your work.
After 32 weeks, the population of bumble bees will be 6.77315 x 10¹⁴ bees.
Solving for the population of bumble bees after 32 weeks:The population of bumble bees triples every week, so the common ratio is 3. The starting population is 20 bees.
The formula for a geometric sequence is:
a_n = a_1 * rⁿ⁻¹
where,
a_n = the nth term in the sequence
a_1 = the first term
r = the common ratio
n = the number of terms.
Using this formula, we can find the number of bees after 32 weeks:
a_32 = 20 * 3³²⁻¹
a_32 = 20 * 3³¹
a_32 = 6.773150 × 10¹⁴

Assuming that the long-run demand for oranges is the same as the short-run demand, you would expect a binding price ceiling to result in a________ that is_________in the long run than in the short run.(Surplus/Shortage) (Larger/Smaller)
If the long-term demand for oranges is the same as the short-term demand, a binding price ceiling will result in a shortage that is larger in long-run demand than the short-run demand. So the answers are shortage and larger.
A shortage occurs when there is a difference between the quantity that is supplied and the quantity that is required of a product, service, or resource. Surplus is a term used to describe situations where there is more supply than demand for a product, service, or resource.
So when the long-run demand is the same as the short-run demand, binding price ceilings typically result in a shortage when there is a lack of supply of products. And, the result will be larger in the case of the long run compared to the short run. Therefore, the first blank can be filled with shortage and the second blank with larger.

minus 30 feet.
a. Write an expression to find the area of the trapezoidal cross
section of the dam.
b. If the height of the dam is 180 feet, find the area
of this cross section.
The area of the trapezoidal cross section of the dam when the height is 180 feet is 33,030 square feet.
What is Quadrilateral?A quadrilateral is a four-sided polygon, having four edges and four corners.
Let's h be the height of the trapezoid.
The length of the bottom base is 2 times "h", or 2h.
The length of the top base is 1/5 times "h", or h/5, minus 30 feet, which we can write as (h/5) - 30.
Area of a trapezoid = (1/2) × (length of bottom base + length of top base) × height.
The expression for the area of the trapezoidal cross section of the dam is:
(1/2) × (2h + (h/5 - 30)) × h
If the height of the dam is 180 feet, we can plug that value into the expression we just wrote to find the area:
Area = (1/2) × (2(180) + ((180/5) - 30)) × 180
Area = (1/2) × (360 + (36 - 30)) × 180
Area = (1/2) × (360 + 6) × 180
Area = (1/2) × 366 × 180
Area = 33,030 square feet
Therefore, the area of the trapezoidal cross section of the dam when the height is 180 feet is 33,030 square feet.

How to convert teaspoons to ounces
To convert teaspoons to ounces divide the ingredient or material's volume times its density by 5.751669.
Divide the volume times the density of the substance or material by 5.751669 to convert a teaspoon measurement to an ounce.
Hence, the volume in ounces is calculated by multiplying the teaspoons by the component or material's density and dividing the result by 5.751669.
ounces = teaspoons × ingredient density / 5.751669
One-third of a tablespoon's volume is represented by a teaspoon. Although a teaspoon is roughly equivalent to 4.9 millilitres, on nutrition labels, a teaspoon is actually equal to 5 millilitres.
The teaspoon is a common volume measurement in the US. Teaspoons can be written as tsp, although they can also be spelled as t, ts, or tspn.
One ounce is equal to 1/16 of a pound in terms of mass/weight. The troy ounce, which is equivalent to 1/12 of a troy pound, should not be confused with the common ounce.

9. If the volume is constant, the pressure of a gas in a container varies directly as the
temperature. (Temperature must be measured in kelvins (K), a unit of measurement used
in physics.). If the pressure is 8 pounds per square inch at a temperature of 500 K, what
is the pressure at a temperature of 600 K?
Answer:
the pressure at a temperature of 600 K is 9.6 pounds per square inch.
Step-by-step explanation:
If the pressure of a gas in a container varies directly as the temperature, then we can use the formula P1/T1 = P2/T2, where P1 is the initial pressure, T1 is the initial temperature, P2 is the final pressure, and T2 is the final temperature.
Using the values given in the problem, we can write:
8/500 = P2/600
Solving for P2, we get:
P2 = (8/500) * 600 = 9.6 pounds per square inch
Therefore, the pressure at a temperature of 600 K is 9.6 pounds per square inch.
In the garden, the ratio of roses to daisies is 2:5. There are 40 roses. How many daisies are there?
The ratio of roses to daisies is 2:5. If there are 40 roses, then there are 100 daisies.

Set up a proportion using the given ratio and the number of roses.
2/5 = 40/x
Cross multiply to solve for x, we get:
2 * x = 5 * 40
Then, simplify the expression:
2x = 200
Divide both sides by 2 to isolate x.
x = 100
Therefore, there are 100 daisies in the garden when there are 40 roses.

y = −3x2 + 6x + 2 y = 3x + 2 solve in a system of non linear equations
Answer: x = 0, Y = 2
x = 1, Y = 5
Step-by-step explanation:
Y = −3x^2 + 6x + 2
Y = 3x + 2
We can set the two equations equal to each other, since they both equal Y:
−3x^2 + 6x + 2 = 3x + 2
−3x^2 + 3x = 0
3x(-x + 1) = 0
This gives us two possible solutions:
x = 0
x = 1
When x = 0, Y = 3(0) + 2 = 2
When x = 1, Y = 3(1) + 2 = 5
Therefore, the solutions to the system of equations are:
x = 0, Y = 2
x = 1, Y = 5

In the triangle we are given Angle A,B andC
a) To find the value of x we will say
angle A + angle B + angle C = 180(sum of angles in triangle add up to 180)
35 + 52 + 3(x+2) = 180
87 + 3x + 6 = 180
3x + 93 = 180
3x = 180 - 93
3x = 87
x = 29
b) To find the measure for angle C we need to substitute the value of x
angle c = 3(x+2)
= 3(29+2)
= 3(31)

The vertex form equation is illustrated below.
How to explain the equationDirectrix (d): The directrix is the horizontal line y = -2.
Focus (F): The focus is the point (0, 2).
Vertex (V): The vertex is the point (0, 0).
Equation: The equation of the parabola is y = 1/4x^2.
The vertex form of a parabola is given by y = a(x-h)^2 + k, where (h, k) is the vertex. We already know the vertex of this parabola, which is (0, 0). To find the value of a, we can use the fact that the distance between the focus and the vertex is equal to the distance between the directrix and the vertex.
The distance between the focus (0, 2) and the vertex (0, 0) is 2 units. The distance between the directrix y = -2 and the vertex (0, 0) is also 2 units. Therefore, we can say that 1/(4a) = 2, or a = 1/8.
So, the vertex form equation of the parabola is y = 1/8(x-0)^2 + 0, which simplifies to y = 1/8x^2.
Vertex: The vertex is (0, 0).
Axis of Symmetry (AOS): The axis of symmetry is the vertical line x = 0.
Domain: The domain of the parabola is all real numbers, because the parabola continues indefinitely in both directions along the x-axis.
Range: The range of the parabola is y >= 0, because the lowest point on the parabola is the vertex (0, 0).
Transformations: The only transformation applied to the basic parabola y = x^2 is a vertical compression by a factor of 1/8.

Answer:
k < 24
Step-by-step explanation:
The phrase "k less than 24" can be written as an algebraic expression using the symbol "<" which means "less than."
So, "k less than 24" can be written as:
k < 24
This means that the value of "k" is smaller than 24. For example, if k = 20, then 20 is less than 24, so the statement "k < 24" is true.
If k = 30, then 30 is not less than 24, so the statement "k < 24" is false.
