Answer:
your answer is a complex number making your question wrong
Step-by-step explanation:
First z²+z+20=0, just to make it a quadratic equation, so we can use the quadratric formula:
x=( -b±√b²-4ac)/2a
so to find a b and c we compare
YOUR QUESTION SHOULD BE Z² +Z-20=O.

The number 70 is decreased to 41. What is the percentage by which the number was decreased, to the nearest tenth of a percent?
Answer:
Decreased percent = 41.4 % (Approx.)
Step-by-step explanation:
Given:
Old number = 70
New number = 41
Find:
Decreased percent
Computation:
Decreased number = 70 - 41
Decreased number = 29
Decreased percent = [29 / 70]100
Decreased percent = 41.42%
Decreased percent = 41.4 % (Approx.)

An arts academy requires there to be 5 teachers for every 125 students and 4 tutors for every 88 students. How many students does the academy have per teacher? per tutor? How many tutors does the academy need if it has 81 students? Pleaseee help
Answer:
25 students peer teacher, 22 students per tutor, 4 tutors for 81 students
Step-by-step explanation:
You need to find the unit rate,
for the teachers, to find the unit rate would be 125 divided by 5. For tutors it would be 88 divided by 4.
Then to find how many tutors you need for 81 students you would need 4 tutors because you want to divide 81 by the unit rate we got (22), and since the answer would be a decimal (3.68.....) you would need to round the whole number up to four because you cant have a decimal of a person.

The coordinate point from the given graph is (3, -5). Therefore, option A is the correct answer.
What is coordinate plane?A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.
From the given coordinate plane, the coordinate point lies in fourth quadrant.
Where, x-coordinate is positive and y-coordinate is is negative.
The coordinate point correspond to x-axis is 3 and coordinate point correspond to y-axis is 5.
So, the coordinate point is (3, -5)
Therefore, option A is the correct answer.

Two families planned to go to the zoo. The entry ticket for one adult was $7.31 and the entry ticket for one
child was $5.66. There were two adults in the group. The families intend to spend no more than
$46.00. What is the greatest number of child tickets that can be purchased?
Answer:
5 children
Step-by-step explanation:
$7.31 x2 = $14.62
$46- 14.62 =$32
5.66 divided by 5 = 28.3
5.66 divided by 6 = 33
and $33 is bigger than $31
So the greatest number of children tickets can be purchased is only 5.
Answer:
5 children
Step-by-step explanation:
Solve
$7.31 x2 = $14.62
$46 - 14.62 =$32
5.66 divided by 5 = 28.3
5.66 divided by 6 = 33
$33 is bigger than $31
Therefore, the greatest number of children tickets can be purchased is only 5.

Sine cannot be greater than 1.
The given conditions cannot form a triangle, there is no possible value of K.
What is sine law?In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
Given that, in a triangle Δ IJK, k = 64 inches, j = 17 inches and ∠J = 68°.
We need to find value of ∠K,
So, using the sine law,
Sin K / k = Sin J / j = Sin I /i
So,
Sin K / k = Sin J / j
Sin K / 64 = Sin 68° / 17
Sin K = 3.5
K = Sin⁻¹(3.5)
K = ERROR
Hence, the given conditions cannot form a triangle, there is no possible value of K.

A right angled triangular prism has length 3m, breadth 2m and height 2.5m. If the mass of the prism is 3.4kg, find its density
Answer:
The density of the prism is 0.453 kilograms per cubic meter.
Step-by-step explanation:
Let suppose that mass in the prism is uniformly distributed. Then, the definition of density ([tex]\rho[/tex]), in kilograms per cubic meter, is defined by the equation below:
[tex]\rho = \frac{m}{V}[/tex] (1)
Where:
[tex]m[/tex] - Mass, in kilograms.
[tex]V[/tex] - Volume of the right angle triangle prism, in cubic meters.
Besides, the volume of the right angle triangle prism is:
[tex]V = \frac{1}{2}\cdot b\cdot h\cdot l[/tex] (2)
Where:
[tex]b[/tex] - Breadth of the base, in meters.
[tex]h[/tex] - Height of the base, in meters.
[tex]l[/tex] - Length of the base, in meters.
If we know that [tex]b = 2\,m[/tex], [tex]h = 2.5\,m[/tex], [tex]l = 3\,m[/tex] and [tex]m = 3.4\,kg[/tex], then the density of the prism is:
[tex]V = 7.5\,m^{3}[/tex]
[tex]\rho = 0.453\,\frac{kg}{m^{3}}[/tex]
The density of the prism is 0.453 kilograms per cubic meter.

After all of the lines are reflected across the y-axis, the true statements are Line l parallels Line m, and Line m parallels Line p.
What is meant by Parallel lines?Parallel lines are two lines in the same plane that are equal distance apart and never intersect. Real-world parallel line examples include railroad tracks, sidewalk edges, street markings, zebra crossings, the surface of pineapple and strawberry fruit, staircases and railings, and so on.Parallel lines are lines in a plane that never meet, no matter how far they are extended. The distance between the parallel lines is constant because they never meet. Parallel lines are defined as lines that do not intersect or meet at any point in a plane. They are always parallel and equidistant from one another.To learn more about Parallel lines, refer to:
