Answer:
50 + 15 -34.99 - 8x
65 - 34.99 - 8(1.10)
30.01 - 8.8
$21.21
Step-by-step explanation:
The amount you have left when each song costs $1.10 is $21.21.
What is expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement.
Given:
You have $50 and a $15 gift card to spend online.
Cost of each sing = $1.10
You purchase a pair of headphones for $34.99 and 8 songs for x dollars each,
Calculate the total amount as shown below,
Total cost = cost of headphones + cost of each song × number of songs
Total cost = 34.99 + 1.10 × 8
Total cost = 34.99 + 8.8
Total cost = $43.79
Calculate the remaining cost as shown below,
Remaining cost = $50 + $15 - total cost
Remaining cost = $65 - $43.79
Remaining cost = $21.21
Therefore, the amount you have left when each song costs $1.10 is $21.21.

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.

For the given pair of equations, give the slopes of the lines, and then determine whether the two lines are parallel, perpendicular, or neither.
10x – 3y = 3
3x + 10y = 30
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. The slope of 10x - 3y = 3 is
(Type an integer or a simplified fraction.)
O B. The slope of 10x - 3y = 3 is undefined.
Answer:
the lines are perpendicular to each other
Step-by-step explanation:
The standard form of equation of a line is y = mx+c
m is the slope of the line
c is the intercept
Given the equations
10x – 3y = 3
3x + 10y = 30
Get the individual slopes
For 10x – 3y = 3
Rewrite in standard form
-3y = -10x + 3
y = 10/3 x - 3/3
y = 10/3 x - 1
Slope of the line is 10/3
For the equation 3x + 10y = 30
10y = -3x+30
y = -3/10 x + 3
Slope of the line is -3/10
Take the product of the slopes
10/3 * -3/10 = -1
Since the product of their slopes is -1, hence the lines are perpendicular to each other

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.

Step-by-step explanation:
All of the following ordered pairs satisfy the function rule y=-3x+2 except
(1, -1)
(4,-10)
(-2,8)
(-3, 12)
Answer:
The ordered pair (-3, 12) DOES NOT satisfy the equation.
Step-by-step explanation:
Given the function
[tex]y=-3x+2[/tex]
Let us substitute all the values to check which points satisfy the function.
FOR (1, -1)
y = -3x+2
substitute x = 1, y = -1
-1 = -3(1) + 2
-1 = -3+2
-1 = -1
TRUE!
Thus, the ordered pair (1, -1) satisfies the equation.
FOR (4, -10)
y = -3x+2
substitute x = 4, y = -10
-10 = -3(4) + 2
-10 = -12+2
-10 = -10
TRUE!
Thus, the ordered pair (4, -10) satisfies the equation.
FOR (-2, 8)
y = -3x+2
substitute x = -2, y = 8
8 = -3(-2) + 2
8 = 6 + 2
8 = 8
TRUE!
Thus, the ordered pair (-2, 8) satisfies the equation.
FOR (-3, 12)
y = -3x+2
substitute x = -3, y = 12
12 = -3(-3) + 2
12 = 9+2
12 = 11
L.H.S ≠ R.H.S
FALSE!
Thus, the ordered pair (-3, 12) DOES NOT satisfy the equation.
Therefore, the ordered pair (-3, 12) DOES NOT satisfy the equation.

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
