What is the rhombus?A rhombus is a quadrilateral having four equal-length sides that are parallel to one another.
As we know Rhombuses' opposing interior angles are congruent, and their diagonals always bisect each other at right angles.
As per the given figure, this means (x + 7) = 90 degrees
⇒ (x + 7) = 90
⇒ x = 90 - 7
Apply the subtraction operation, and we get
⇒ x = 83
Thus, the value of x is ABCD a kite would be 83 units.

Complete the square and put this function in vertex form: f(x)=x^2+20x+96
Answer:
f(x) = (x+10)^2 - 4
Step-by-step explanation:
vertex form is y = a(x-h)^2+k
to complete the square, we want to add a number on both sides so x^2+20x+whatver the number is, is the square of something
to find that number take 20, divide by 2, and then square it to get 100.
so, you would get f(x)+100 = x^2+20x+100+96
subtract 96 on both sides: x^2+20x+100 = f(x) + 4
factor: f(x) = (x+10)^2 - 4

What’s the answer for X
8+x=3.5x-1
Answer:
x = 3.6
Step-by-step explanation:
8 + x = 3.5x - 1
x - 3.5x = -1 - 8
-2.5x = -9
x = 3.6
Answer:
x = 3.6
Step-by-step explanation:
8 + x = 3.5x - 1
subtract 8 from both sides
x = 3.5x - 9
subtract 3.5x from both sides

Know more about line:
A line has length but not width. A line is a type of geometric shape that can move in either direction. A line consists of an infinite number of points. It is infinite and has no end on either side. The row is one-dimensional.
In geometry, the term line or straight line was introduced by ancient mathematicians to denote straight objects of negligible width and depth. It is often described as two points.
A line in a plane is often defined as a set of points whose coordinates correspond to a given linear equation in the sense of analytic geometry, while a line can be an independent object distinct from the points on it. drop geometry.
Here given two points are (−3,−4) and (−7,16).
According to rule,slope of the line that goes through points (−3,−4) and (−7,16)

Cost of 40 pounds of apples at David's apple is $50.
Cost of 40 pounds of apples at Pam's orchards is $37.5.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Anna want to pick 40 pounds of apples,
Now, At David's apple orchard cost of first 10 pounds = $2 per pound
And, Each additional pounds $1 per pound.
So, Cost of 40 pounds of apples at David's apple is calculated as;
Cost of first 10 pounds = 10 * 2 = $20
And, Cost of 30 pounds of additional apples = 30 * 1 = $30
Hence, Cost of 40 pounds of apples at David's apple = $20 + $30
= $50
At Pam's orchards first cost of first 10 pounds = $1.50
And, Each additional pounds $0.75 per pound.
So, Cost of 40 pounds of apples at Pam's orchards is calculated as;
Cost of first 10 pounds = 10 * 1.50 = $15
And, Cost of 30 pounds of additional apples = 30 * 0.75 = $22.5
Hence, Cost of 40 pounds of apples at Pam's orchards = $15 + $22.5
= $37.5
Therefore,
Cost of 40 pounds of apples at David's apple is $50.
Cost of 40 pounds of apples at Pam's orchards is $37.5.

The transformation was a 270° rotation about the origin.
The transformation was a 360° rotation about the origin.ear pair
Answer:
It's a 180 rotation
Step-by-step explanation:
The first set of chords are in the first quadrant while the second set of chords are in the third quadrant. If you draw the first triangle on a second sheet of paper in the same place a the first triangle and hold the paper so that the triangle you drew of the first triangle is directly on top of the first triangle and then hold the paper at the point (0,0) and move the paper 180 degrees, it doesn't matter which direction cause it's 180 degrees, the points of the triangle will have ended up in the third quadrant. So it's 180 degree rotation

xz Is the prependicualr disector of segment WY. WY=66. Solve for k. Enter a number only.
Answer:
k = 4
Step-by-step explanation:
A perpendicular bisector is defined as a line or a line segment that divides a given line segment into two parts of equal measurement.
So WX = XY or WX = 1/2 WY
using WX = 7k + 5 and WY = 66
7k + 5 = 66/2
7k = 33 - 5
7k = 28
k = 4

Answer:
-3x + 40
Step-by-step explanation:
The constant given is 40 gallons and the rate at which the water in the bathtub decreases is 3 gallons per minute.
To write this as an equation we model 40 as the starting constant that is positive and, because the water is decreasing, we use a negative slope.
-3x represents the decrease in water over x intervals (Which in this case is minutes) and 40 gallons represent the initial value (water in the bathtub).
Therefore the water in the bathtub can be modeled with the equation
-3x + 40

the area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
The 2 legs are perpendicular to each other , so
b = 6 and h = 6 , then

In a class of 25 students, 15 are female and 16 have an A in the class. There are 12 students who are female and have an A in the class. What is the probability that a student has an A given that the student is female?
Answer:12/16
Step-by-step explanation:
The probability that a female student has an A in the class is 0.8 or 80%.
How to calculate the probability?To calculate the probability that a student has an A given that the student is female, we can use the formula for conditional probability:
[tex]P(A|F) = \dfrac{P(A U F)} { P(F)}[/tex]
where P(A|F) is the probability of having an A given that the student is female, P(A and F) is the probability of being both female and having an A, and P(F) is the probability of being female.
We are given that there are 25 students in the class, 15 of whom are female and 16 of whom have an A. We are also given that there are 12 students who are both female and have an A.
Using this information, we can calculate the probabilities as follows:
P(F) = 15/25 = 0.6
P(A and F) = 12/25
The probability that a student has an A given that the student is female is:
[tex]P(A|F) = \dfrac{P(A U F)} {P(F)} \\P(A|F) = \dfrac{\dfrac{12}{25} }{ (\dfrac{15}{25})} \\P(A|F)= 0.8[/tex]
The probability is 80%.
