Answers

Answer 1
Answer: x - 14.50 = 53
^ original equation ^
x - 14.50 = 53
   +14.50  +14.50
x = 67.50

The original price is 67.50$

You score an 86 on the first of two exams. Write and solve an equation to find the score x that you need on the second exam to have a mean score of 90.

Answers

The score in the second exam is 94.

What is a Mean?

  • Mean is the average value of all the numbers in the given set.
  • Mean is calculated to get the average outcome.

Given:

Score in the first exam = 86

Mean score of two exams = 90

We have to find the score of second exam.

Let the score of second exam be x.

We know, mean is given by:

⇒ Mean = (Total score in all the exams) / (Total number of exams)

Here,

Total score in all the exams = 86 + x

Total number of exams = 2

Mean = 90             (given)

⇒ 90 = (86 + x)/2

⇒ 90 × 2 = 86 + x

⇒ 180 = 86 + x

⇒ x = 180 - 86

x = 94

Therefore, the score in the second exam is 94.

I haven't touched on mean, mode, medium, and range in a little while so I could be wrong, but if (mean) means average, i think average is adding 2 grades together then dividing the number of exams, so the average needs to be 90, so what I did was i found the difference between the original grade on the first exam, so 90-86=4, so i guessed at 94 being the next grade needed. (86+94)/2=90. 86+94=180 then divide 180 by 2 and it equals 90. so yeah your answer is 94.

What word describes the relationship between oppsite angles of a parallelogram?

Answers

The word that describes the relationship between opposite angles of a parallelogram is "congruent," indicating that these angles have the same measure.

The word that describes the relationship between opposite angles of a parallelogram is "congruent."

In a parallelogram, opposite angles are congruent, meaning they have the same measure.

This property is a consequence of the parallel sides in a parallelogram.

When two parallel lines are intersected by a transversal, such as the sides of a parallelogram, several pairs of angles are formed.

Opposite angles, also known as alternate angles or vertical angles, are formed by the intersection of the diagonals wit hin the parallelogram.

By definition, vertical angles are congruent.

This means that opposite angles in a parallelogram have equal measures.

If one opposite angle is x degrees, then the other opposite angle will also be x degrees.

This property holds true for all parallelograms, regardless of the specific dimensions or shape of the parallelogram.

Whether the parallelogram is a rectangle, a square, or a rhombus, the relationship between opposite angles remains the same.

Understanding this relationship allows us to use the congruence of opposite angles as a tool in solving problems involving angles within a parallelogram.

It provides a basis for making geometric deductions and calculations based on the equality of angle measures.

Yolanda owns 4 rabbits. She expects the number of rabbits to double every year.Write an equation to model this situation.

Answers

R=Number of rabbits

y=Years that have passed by { y ≥ 0 }

R=f(y) --> R is a function of y.
---------------------------------------------

Note that when:

y=0, R=4 ---> Point: (0, 4)

y=1, R=8 ---> Point (1, 8)

y=2, R=16 ---> Point (2, 16)

y=3, R=32 ---> Point (3, 32)

y=4, R=64 ---> Point (4, 64)

--------------------------------------------

So the equation you want is going to form a curved graph.

That equation is:

R={ 2 }^( y+2 )

*You can test out this function on any decent graphing software.
This is an exponential function.

At year x, the number of rabbits would be as follows:

y=4e ^((x*(In2)))
