What is rhombus?A quadrilateral with equal-length sides is a rhombus. The angles at the opposite vertex are equal, and the opposite sides are parallel. In a rhombus, the opposing sides are parallel. In a rhombus, the opposing angles are equal. Diagonals in a rhombus cut each other at right angles. A rhombus' angles are divided by diagonals.
What is diagonal?A diagonal in mathematics is a line that joins two solids or polygons whose vertices are not on the same edge. Generally speaking, a diagonal is a sloping or slanting line that joins the vertices of a shape. The term "diagonal" refers to lateral shapes with sides, edges, and corners. A diagonal is a line segment that joins two opposing polygonal vertices (or corners). In other words, a diagonal is a line segment that joins two polygonal vertices that are not adjacent to one another. It connects a polygon's vertices, excluding the figure's edges.

ABC High School is debating whether or not to write a policywhere all students musthave uniforms and wear them during school hours. In a survey,45% of the studentswanted uniforms, and 55% did not.Calculate the probability that a person selected at random fromABC High School will want the school to have uniforms or willnot want the school to have uniforms.
If 45% don't want uniforms, it means that 45 out of 100 students don't want them, so the probability is 45/100 = 9/20
And 55% want unifrms, so the probability = 55/100 = 11/20

Let's draw a rough figure:
Here, h is the distance we are solving for.
Now,
With respect to the given angle 30 degrees, we have the hypotenuse and want to find the opposite side.
The trig ratio relating opposite side and hypotenuse is SINE.
Thus, we can write:
[tex]\sin (30)=\frac{opposite}{\text{hypotenuse}}=\frac{h}{40}[/tex]Cross multiiplying, we solve for h [remember, value of sin(30) is 1/2]:
[tex]\begin{gathered} \sin (30)=\frac{h}{40} \\ h=40\times\sin (30) \\ h=40\times\frac{1}{2} \\ h=20 \end{gathered}[/tex]The height of the boat ramp is 20 feet.

Thomas is buying football jerseys for his high school football team.
The cost of each jersey is $80.
The company also charges a processing fee of $100.
We could write an equation that models Thomas's total cost for purchasing x
number of jerseys.
Since for every x jerseys Thomas buys, he pays
[tex]80x\text{ dollars}[/tex]But he also has to pay the company's processing fee, this is independent of the quantity bought.
So, the total cost for buying x number of jerseys is;
[tex]y=80x+100\text{ dollars}[/tex]ii. What is Thomas's total cost, if he buys 55 jerseys?
We can use our formula,
[tex]\begin{gathered} y=80x+100\text{ , when x =55, we have;} \\ y=80(55)+100 \\ y=4400+100 \\ y=4500\text{ dollars} \end{gathered}[/tex]Therefore, Thomas's total cost for 55 jerseys is $4500

when he is 100 feet away from the pole?
Answer:
375!
Step-by-step explanation:

a) to eliminate the y variable we have
[tex]\begin{gathered} 2y \\ -4y \end{gathered}[/tex]in order to be eliminated both terms must have the same value and different sign,in other words the addition must equla zero, so weed a number (a) that makes the term from teh first equation equals (4y)
so

Write a general formula to describe the variation. M varies directly with the square of d and inversely with the square root of x; M=12 when d=3 and x=4
Given that 'M' varies directly with the square of 'd',
[tex]M\propto d^2[/tex]Given that 'M' varies inversely with the square root of 'x',
[tex]M\propto\frac{1}{\sqrt[]{x}}[/tex]Combining the relationships,
[tex]M\propto\frac{d^2}{\sqrt[]{x}}[/tex]Let 'k' be the constant of proportionality. Then,
[tex]M=k\cdot\frac{d^2}{\sqrt[]{x}}[/tex]Given that M=12 when d=3 and x=4,
[tex]\begin{gathered} 12=k\cdot\frac{(3)^2}{\sqrt[]{4}} \\ 12=k\cdot\frac{9}{2} \\ k=\frac{12\cdot2}{9} \\ k=\frac{8}{3} \end{gathered}[/tex]Substitute the value of this constant in the general expression,
[tex]M=\frac{8}{3}\cdot\frac{d^2}{\sqrt[]{x}}[/tex]Thus, the required general formula to describe the relation is obtained as,

It cost $159 to drive the van for 120 miles
Explanation:
The flat fee of the van = $99
The charge per mile = $0.50
Let m represent the number of miles
T = total cost
The total cost becomes:
T = 0.5m + 99
When you drive 120 miles, m = 120 miles
T = 0.5(120) + 99
T = 60 + 99
T = $159
Hence, it cost $159 to drive the van for 120 miles

Find the image of (1,2) after a reflection about x=3 followed by a reflection about x=7.
EXPLANATION
Given the point (1,2), if we reflect the point the new image must be at the same distance from the reflective line just at the original image.
Therefore when (1,2) is reflected over x= 3 the image becomes
[tex](5,2)[/tex]As the distance between line x=3 is 2 units on both sides.
When we then reflect (5,2) over x =7, using the same idea above the image becomes

How to calculate an arithmetic sequence?Mathematically, the nth term of an arithmetic sequence can be calculated by using this expression:
aₙ = a₁ + (n - 1)d
Where:
d represents the common difference.a₁ represents the first term of an arithmetic sequence.n represents the total number of terms.Next, we would determine the common difference by using the 25th term of this arithmetic sequence:
-48 = 0 + (25 - 1)d
-48 = 24d
d = -48/2
d = -2.
For the nth term of this arithmetic sequence with -10, we have:
aₙ = a₁ + (n - 1)d
-10 = 0 + (n - 1)-2
-10 = -2n + 2
2n = 12
n = 6.
For the 8th term of this arithmetic sequence, we have:
a₈ = a₁ + (n - 1)d
a₈ = 0 + (8 - 1)-2
a₈ = -14.
For the nth term of this arithmetic sequence with -20, we have:
aₙ = a₁ + (n - 1)d
-20 = 0 + (n - 1)-2
-20 = -2n + 2
2n = 22
n = 11.
For the 19th term of this arithmetic sequence, we have:
a₁₉ = a₁ + (n - 1)d
a₁₉ = 0 + (19 - 1)-2
a₁₉ = -36.

What is improper fraction and mixed fraction?
A mixed fraction is one that has both a correct fraction and a whole number portion, and whose value is consistently greater than 1. When the numerator is always higher than or equal to the denominator, the fraction is said to be inappropriate. 4/3, 7/3, 11/5, and other incorrect fractions are a few instances.
Here the road trip is 2457 miles long .
