Total amount Parker will pay for s songs = 6 + 0.50s
Step-by-step explanation:
Cost per month = $6
Cost of Offline download = $0.50 per song
A. How much total money would
Parker have to pay in a month in which he downloaded 50 songs?
Total amount Parker will pay = $6 + $0.50(50)
= 6 + 25
= $31
Parker will have to pay $31 in a month in which he downloaded 50 songs.
B. How much would
he have to pay if he downloaded s songs?
Total amount Parker will pay for s songs = $6 + $0.50 * s
= $6 + $0.50s

see below
Step-by-step explanation:
⇒ -7y - (-12y) = -7y + 12y = 5y
⇒ 15xy - (-6xy) = 15xy + 6xy = 21xy
⇒ -53va - 32va = - 85av
⇒ 64 / 0.8 -5.6 / 7
= 448 - 7.48

Evaluate the expressions if x = 10, y = 5, and z = 1.
⇒ x/y = 10 / 5 = 2

Dr. Ames earns an annual salary of $265,000. If social security is 8% of your income, then how much will Dr. Ames pay each year in social security? $13,250 $21,200 $15,900 $18,40063
Answer:
The correct answer is b.
Step-by-step explanation:
Giving the following information:
Annual salary= $265,000
Social security is 8% of his income.
To calculate the annual expending on social security, all we have to do is multiply the annual salary for the expend percentage.
Annual expense= 265,000*0.08
Annual expense= $21,200
A rectangular prism has a volume of 170 cubic centimeters. The length of the prism is 5 centimeters, and the height of the prism is 17 centimeters. What is the width of the prism. Enter the answer in the box .
Answer:
The width of the prism is 2 cm
Step-by-step explanation:
The given parameters are;
The volume of the prism = 170 cm³
The length of the prism = 5 cm
The height of the prism = 17 cm
The volume of the prism is given by the relationship v = Length, l × Height, h × Width, w
Therefore;
The volume of the prism = 5 cm × 17 cm × w = 170 cm³
Which gives;
w = 170 cm³/(5 cm × 17 cm) = 170 cm³/(85 cm) = 2 cm
∴ The width of the prism = 2 cm.
The width of the prism is 2cm given length of the prism is 5 centimeters, and the height of the prism is 17 centimeter.
The formula for calculating the volume of a rectangular prism is expressed as:
V = LWH where:
L is the lengthW is the widthH is the heightGiven the following:
V = 170cm³
L = 5cm
H = 17cm
Required
Width
Substitute the given values into the formula:
170 = 5 * 17 * W
170 = 85W
W = 170/85
W = 2cm
Hence the width of the prism is 2cm

soolve the abslut value of |2x-1|=3
Answer: x = 2 or x = -1
Step-by-step explanation: When you are solving an absolute value equation, you can split the problem up into two separate equations.
The first equation will look just like the original problem,
except for the absolute value signs (2x - 1 = 3).
The second equation will look just like the first,
but the right side will be changed to a negative (2x - 1 = -3).
Now solve each equation from here to get x = 2 or x = -1
A jar contains 16 black balls,13 blue balls and 2 red balls in a bag. A ball is drawn in random. Find the probability of drawing a black ball? Find the probability of drawing a blue ball? Find the probability of not drawing a red ball?
Answer:
black: 16/31 blue: 13/31 red 2/31
16 black, 13 blue, 2 red
16+13+2 = 31 total
16/31 is the probability of picking black
13/31 is the probability of picking blue
2/31 is the probability of picking red, so 29/31 is the probability of not picking red (since 31-2 = 29 are not red out of 31 total)

Find the value of x.
A pair of intersecting lines is shown. The angle above the point of intersection is labeled left parenthesis 7 x minus 8 right parenthesis degrees. The angle directly opposite below the point of intersection is labeled left parenthesis 6 x plus 11 right parenthesis degrees.
A. –19
B. 125
C. 19
D. 55
The value of x is 19. Therefore, option C is the correct answer.
From the given figure, the two angles are (7x-8)° and (6x+11)°.
What is the vertical angle theorem?Vertical angles are a pair of non-adjacent angles formed by the intersection of two straight lines. In simple words, vertical angles are located across from one another in the corners of the "X" formed by two straight lines. They are also called vertically opposite angles as they are situated opposite to each other.
Now, (7x-8)° = (6x+11)° (Vertically opposite angles are equal)
⇒ 7x-6x = 11+8
⇒ x = 19°
The value of x is 19. Therefore, option C is the correct answer.

Answer: girls=20, sister=10
Step-by-step explanation:
Let x = the girl's sister's age (present)
Let 2x= the girl's age (present)
-------------------------------------------------------------
According to the question
(x+5)(2x+5)=375
Expand parentheses by FOIL (First Outer Inner Last)
2x²+5x+10x+25=375
Combine like term (5x and 10x)
2x²+15x+25=375
Subtract 375 on both sides
2x²+15x+25-375=375-375
2x²+15x-350=0
Find the factors (cross factor)
(x-10)(x+17.5)=0
x=10 or x=-17.5 (rej) ⇔ the age can't be negative

2 ABC Company has a large piece of equipment
that cost $85,600 when it was first purchased 6
years ago. The current value of the equipment is
$30,400. What is the average depreciation of the
equipment per year?
F. $ 5,800
G. $ 9,200
H. $15,200
J. $27,600
K. $42,800
Answer:5,800
Step-by-step explanation:
The average depreciation of the equipment per year is $9200.
What is depreciation?The monetary value of an asset decreases over time due to use, wear and tear or obsolescence, this is called as depreciation.
Now it is given that,
Cost of the equipment = $85,600
current value of the equipment is given as $30,400
Duration for which the equipment was used = 6 years
Now the depreciation of the equipment is given as,
Total depreciation in the price of the equipment
= Cost of the equipment - current price of the equipment
So, total depreciation = $85,600 - $30,400 = $55,200
Now,
Average yearly depreciation = Total depreciation ÷ Years used
Average depreciation = 55,200/6
⇒Average depreciation = $9200
Therefore, average depreciation of the equipment per year is $9200.

y = -0.2*x^2 is a vertical dilation of scale factor 0.2 followed by a reflection over the x-axis of y = x^2
How to relate these two graphs?
We have two functions:
f(x) = x^2
g(x) = -0.2*x^2
The transformations used are:
Reflection over the x-axis.
For a function f(x), a reflection over the x-axis is written as:
g(x) = -f(x).
Vertical dilation.
For a function f(x), a vertical dilation of scale factor k is written as:
g(x) = k*f(x).
So here we can see that we have a vertical dilation of scale factor 0.2, followed by a reflection over the x-axis.
g(x) = -0.2*f(x).
So, g(x) opens in the opposite direction than f(x), and grows slower (because of the dilation).

Tina has 1/2 of a pan of cornbread left from a dinner party. She eats 1/2 of the leftover part the next night. How much of the whole pan does tina eat? Write and solve this equation
Answer:
Tina ate 3/4 of the whole pan of cornbread.
Step-by-step explanation:
Let the amount of cornbread in the initial pan be x.
After the dinner party, Tina has 1/2 of x left; That is 1/2x
If she eats 1/2 of the leftover, that will be 1/2 of 1/2x that is eaten. This will be 1/4x that is eaten.
To find the potion of the whole pan that Tina ate, we will add the potion she ate during the party to the portion of the leftover she ate the next night.
That will be 1/2x + 1/4x =3/4x
Therefore, Tina ate 3/4 of the whole pan of cornbread.
