Parker signed up for a streaming music service that costs $6 per month. The service allows Parker to listen to unlimited music, but if he wants to download songs for offline listening, the service charges $0.50 per song. How much total money would Parker have to pay in a month in which he downloaded 50 songs? How much would he have to pay if he downloaded ss songs?
Answer:
Parker will have to pay $31 in a month in which he downloaded 50 songs.
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
Total amount Parker will pay for s songs = 6 + 0.50s

The father is three times as old as his son, Joe. Joe is four years older than his sister, Alexa. Alexa is twice as old as Rocky. Let R equal Rocky's age. Write an algebraic expression. Please Help!
Answer:
R=(F/3-4)/2
Step-by-step explanation:
Father = F
Joe = J
Alexa = A
R= Rocky
F=3J
A+4=J
A=2R
F/3=J
A=J-4
A=F/3-4
2R=F/3-4
R=(F/3-4)/2

Use the Quotient Rule to find the UNSIMPLIFIED version of the derivative. R(w)=3w+w^4/ 2w^2+1.
Pls show work!!!
From your previous questions, you know
(3w + w⁴)' = 3 + 4w³
(2w² + 1)' = 4w
So by the quotient rule,
R'(w) = [ (2w² + 1)•(3w + w⁴)' - (3w + w⁴)•(2w² + 1)' ] / (2w² + 1)²
That is, the quotient rule gives
R'(w) = [ (denominator)•(derivative of numerator) - (numerator)•(derivative of denominator) ] / (denominator)²
I'm not entirely sure what is meant by "unsimplified". Technically, you could stop here. But since you already know the component derivatives, might as well put them to use:
R'(w) = [ (2w² + 1)•(3 + 4w³) - (3w + w⁴)•(4w) ] / (2w² + 1)²

Answer:
The value of x is 20 ⇒ A
Step-by-step explanation:
When a line intersects two parallel lines, then some pairs of angles are formed
Alternate interior angles which equal in measuresAlternate exterior angles which equal in measuresCorresponding angles which equal in measuresAdjacent interior angles which are supplementary (the sum of their measures is 180°)In the given figure
∵ Lines l and m are parallel
∵ They are intersected by a line
∴ The angles of measures (3x + 5)° and 65° are alternate interior angles
→ That means they are equal in measures
∵ Alternate interior angles are equal in measures
∴ (3x + 5)° = 65°
→ Subtract 5 from both sides
∵ 3x + 5 - 5 = 65 - 5
∴ 3x = 60
→ Divide both sides by 3
∴ x = 20
∴ The value of x is 20

Rodger put $1,000 in a bank account that pays 5% annual simple interest. At the end of four years, how much interest has he earned and what is the balance of his account
Answer: He has earned $200 interest and the balance of his account is $1,200.
Step-by-step explanation:
Given: Principal : P = $1,000
Simple interest rate : r = 5% = 0.05
Time: t = 4 years
Simple interest = [tex]Prt[/tex]
[tex]=1000\times0.05\times4=200[/tex]
i.e. Simple interest = $200
Balance of account = Principal + Simple interest
= $1,000 + $200
= $1,200
Hence, he has earned $200 interest and the balance of his account is $1,200.

Mr. Miller has a 20-foot ladder, which he
wants to reach 18 feet up the side of his
house. To the nearest foot, how far from the
base of the house should he place the
ladder?
Answer:
8 ft
Step-by-step explanation:
the ladder will make a right angle triangle with the house. The hypotenuse of the triangle is the ladder, 20 ft, and the height of the triagnle is 18 ft.
Solve for the base of the right angle triangle using pythagorean's theorem:
c=20, a=18, b=?
[tex]b^{2}=c^{2} - a^{2}\\b^{2}=20^{2} - 18^{2}[/tex]
[tex]b=\sqrt{72}[/tex]
[tex]b= 8.49 ft[/tex]
round to the nearest foot,
b = 8 ft
A sum of money invested at the compound interest payable yearly has interest in
2 years and 4 years are Rs. 4,200 and Rs. 9282 respectively. Find the rate of
interest
Answer:
49% and 30% respectively
Step-by-step explanation:
Step one:
Given data
Principal = Rs. 4,200
Final Amount= Rs. 9282 respectively
time = 2 years and
time = 4 years
Required
The rate of interest for 2 and 4 years
Step two:
the compound interest formula is
A= P(1+r)^t
for 2 years
Substitute
[tex]9282= 4200(1+r)^2\\\\9282/4200= (1+r)^2[/tex]
[tex]1+r= \sqrt{\frac{9282}{ 4200} }\\\\1+r= \sqrt{2.21} \\\\1+r= 1.49\\\\r=1.49-1\\\\r= 0.49\\\\[/tex]
the rate is 49%
For 4 years we have
[tex]9282= 4200(1+r)^4\\\\9282/4200= (1+r)^4[/tex]
[tex]1+r= \sqrt[4]{\frac{9282}{4500} } \\\\1+r=\sqrt[4]{2.21} \\\\1+r= 1.30\\\\r=1.30-1\\\\r= 0.30\\\\[/tex]
the rate is 30%

a, b, and c represent three different digits. If you add up all of the six two - digit numbers that can be written with these digits, where you don't use the same digit twice in each number, then the sum will be 528. Find these digits.
Answer:
The answer is 7, 8 and 9. The Two-digit numbers are: ab, ac, ba, bc, ca, cb
The Sum of them is: 10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 528
22a + 22b + 22c = 528
a + b + c = 528/22
a + b + c = 24 The only option of three different digits with the sum of 24 is 7, 8 and 9.
Hope this helps, stay safe, and merry christmas!

The ratio of the number of cars to dolls in a toy store is 3/20 . The ratio of the number of male dolls to the number of female dolls is 3:5 There are 500 female dolls. How many toys are there?
Answer:
800 dolls
Step-by-step explanation:
Step one:
given data
we are told that the ratio of the number of male dolls to the number of female dolls is 3:5 , i.e male dolls to female dolls is 3 to 5
given that there are 500 female dolls, let the number of male dolls be x
Step two:
3/5= x/500
cross multiply we have
3*500=5x
1500=5x
divide both sides by 5
x=1500/5
x=300
hence there are 300 male dolls
The total dolls is 300+500= 800 dolls
Eric conducted a survey of the cars in four parking lots and wrote the following observations:
15 of the 36 cars in lot 1 were blue
43 of the 92 cars in lot 2 were blue
12 of the 30 cars in lot 3 were blue
32 of the 52 cars in lot 4 were blue
Based on the survey, which parking lot had the greatest percentage of blue cars? (
Answer:
1- 42%
2- 47%
3- 40%
4- 62%
parking lot 4 had the greatest percentage of blue cars
Step-by-step explanation:
Answer:
Lot 4 had the greatest percentage of blue cars.
Step-by-step explanation:
15 of the 36 cars in lot 1 were blue = 41.66 %
43 of the 92 cars in lot 2 were blue = 46.73 %
12 of the 30 cars in lot 3 were blue = 40%
32 of the 52 cars in lot 4 were blue = 61.53 %
A theater, the admission price for children is $4 and the admission price for adults is $8. The total amount the theater collects in admissions for the day is $1848. The total number of visitors is 283. Let be the number of children and let y be the number of adults. Which system represents the situation?
Answer:
[tex]4x+8y= 1848\\\\x+y= 283[/tex]
Step-by-step explanation:
Step one:
The admission price for children is $4
The admission price for adults is $8
Let be the number of children and
let y be the number of adults.
The total amount the theater collects in admissions for the day is $1848.
4x+8y= 1848-----------1
The total number of visitors is 283.
x+y= 283----------------2
Step two:
the system of equation for the situation is
4x+8y= 1848
x+y= 283

a conical tank with vertex down is 10 feet across the top and 12 feet deep. If water is flowing out of the tank at a rate of 12 cubic feet per minute, find the rate at which the water level is dropping when radius of water level is 4ft.
Answer:
The water level is dropping at a rate of 0.24 ft/s
Step-by-step explanation:
Here, we simply want to calculate the change in depth (height of the cone) , given the volume change
Mathematically, we have the volume of a cone as;
V = 1/3 * π * r^2 * h
we are given dv/dt as 12 ft^3/m
dv/dh = 1/3 * π * r^2
Substituting the value for the radius, we have
dv/dh = 1/3 * 22/7 * 4^2 = 50.29
dh/dt = dh/dv * dv/dt
dh/dv = 1/(dv/dh) = 1/50.29
Thus,
dh/dt = 1/50.29 * 12
dh/dt = 0.24 ft/s
