To be eligible for certain tax programs you can't make $15,000 or less per year nor $45,000 or more per year. Create an inequality to represent the range of this scenario interpret a salary that would be eligible for the tax programs, and then Identify a salary that would not be eligible,
Answer:
there is ia $30,000 range in which you are eligible and $14,000 and $46,000 thousand dollars are not eligible
The range of this scenario interpret a salary that would be eligible for the tax programs,
45000 > n > 15000.
A salary that would not be eligible,
n ≤ 15000 and n ≥ 45000.
What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given:
To be eligible for certain tax programs,
you can't make $15,000 or less per year nor $45,000 or more per year.
That means,
n > 15000
And n < 45000.
The range of this scenario interpret a salary that would be eligible for the tax programs,
45000 > n > 15000.
A salary that would not be eligible,
n ≤ 15000 and n ≥ 45000.
Therefore, the required values are given above.

Answer:
180 degrees
Step-by-step explanation:
Lets call the unknown Angle next to angle C "ANGLE D"
1. Your given the angle 45 degrees.
2. (45 degree angle) can correspond to Angle D,
because of the alternate exterior angles definition- two lines (angles) that are on diagonal opposite sides of one another outside of the two parallel lines.
3: (45 degree angle) is an alternate exterior angle to its corresponding diagonal angle Angle D, this can also be said for (Angle C) and (angle B).
4: Now that the angles are known- (Angle C) is an alternate exterior angle to (Angle B). (45 degree angle) is an alternate exterior angle to Angle D
We can now use
The alternate Exterior angles Theorem- If two parallel lines are intersected by a transversal, then the alternate exterior angles are congruent.
4: we now know that (45 degree angle) is congruent to Angle D. And (angle C) is congruent to (angle B).
-Angle D and (45 Degree angle) are both 45 degrees since they are both alternate exterior angles to one another. And (Angle C) and (Angle B) have the same angle measure because they are alternate exterior angles to one another.
5: take a look at (angle C) and Angle D notice the transversal- (line that intersects two parallel lines), and how it creates a linear pair. Notice that the transversal has created the angles of (angle B) and (45 degree angle) to be linear pairs as well.
- Linear Pair definition- If two adjacent lines have rays pointing in opposite directions they are linear pairs.
Also the definition of a Linear Pair identifies as Supplementary. Supplementary is an angle that has a total of 180 degrees.
6: If (45 degree angle) and Angle B make a linear pair, and linear pairs have a total of 180 degrees, then solve for the angle measure of (angle B)
180= 45 + measure of (angle B)
180-45= 135
135 = measure of (angle B)
45 + 135= 180 degrees
7: The measure of (Angle B) is 135 degrees and since (Angle B) is congruent to (Angle C), the measure of (Angle C) is 135 degrees.
Therefore, (45 degree angle) and (Angle B) are 180 degrees total and (Angle C) and (Angle D) are 180 degrees total.
Now, that all exterior angle measures are found, it can be concluded that Angle A) is the same as the total measure of its exterior angle, since it is the same line that makes up the linear pair.
Therefore, (Angle a) is 180 degrees.

A weight lifter lifts a setof 1250kg weights a vertical distance of 2m in a weight lifting contest what potential energy do the weights now possess
Answer:
U = mgh = (1250 kg)(9.8 m/s2)(2m) = ? J
HOPE THIS HELPS
The potential energy of the weights is 24500 J.
What is potential energy?Potential energy is the energy an object possesses due to its position.
It depends on its mass, height, and the force of gravity.
Potential energy = mgh
Where g is the acceleration due to gravity and g is 9.8 m/s².
We have,
Potential energy = mgh
where:
m = mass of the weights
g = acceleration due to gravity
h = vertical distance of the weights
Now,
Substituting the values.
Potential energy.
= 1250 x 9.8 x 2
= 24500 J
Thus,
The potential energy of the weights is 24500 J.

Explain why the square root of a number is defined to be
equal to that number to the 1/2 power
9514 1404 393
Answer:
(x^(1/2))^2 = x^(2/2) = x
Step-by-step explanation:
The square root of a number, when multiplied by itself, gives the original number.
(√x)(√x) = x
The rule for exponents is that powers of the same base, when multiplied, will be the base to the sum of those powers.
(a^b)(a^c) = a^(b+c)
Also, the first power of a number is that number itself.
__
[tex]x^{\frac{1}{2}}\times x^{\frac{1}{2}}=x^{\frac{1}{2}+\frac{1}{2}}=x^1=x\\\\ \text{Compare to ...}\\\\ \sqrt{x}\times\sqrt{x}=x[/tex]
Answer:
Squaring and square root are inverses, so one should "undo" the other. That is, squaring the square root of a number results in the number. Using the power of a power rule, you multiply the exponents. Since a number to the first power is itself, the product of the exponents must equal 1. This means that the power of the square root must be the reciprocal of 2, or one half.

ABCD is a parallelogram. Determine the measure of ∠B.
Question 19 options:
A) 52°
B) 96°
C) 39°
D) 78°
Answer:
D
Step-by-step explanation:
In parallelogram, opposite angles are congruent.
m∠B = m∠D
3x = x + 52 {Subtract x from both sides}
3x - x = 52 {Combine like terms}
2x = 52 {Divide both sides by 2}
x = 52/2
x = 26
m∠B = 3x = 3*26 = 78
I think the answer should be D)
because both sides should be equal to each other, and if you take 78/3, it equals 28, and 28+52=78, so both sides equal 78, which makes it D
