Answer:
50 songs at $35
Step-by-step explanation:
Answer:
x = 50, y = 35
Step-by-step explanation:
Solve this system of linear equations by using substitution. Equate the two equations to one another, thus eliminating y:
0.4x + 15 = 0.2x + 25
subtract 0.2x from both sides, obtaining: 0.2x + 15 = 25, or, after combining the constants, 0.2x = 10.
Finally we divide both sides by 0.2, which results in x = 50.
Use the first equation to find y: y = 0.4(50) + 15 = 20 + 15 = 35

Use the graph of g to solve.
Find g(-16)
Answer:
g(-16) = 6
Step-by-step explanation:
We want the value of the function when x = -16
The function is constant from x = -8 to the left. The value is 6
g(-16) = 6
Answer:
g(-16) = 6
Step-by-step explanation:
The upper horizontal line with an arrow to the left means that the value of function g remains at 6 from x = -8 as it approaches negative infinity. Since -16 is in the interval from -8 to -infinity, then
g(-16) = 6

Which equation in the form y = mx + cs models Emma's situation?
O y = 20x + 0.15
O y = 20x + 15
O y = 20x + 0.15s
y = 20x + 15s
Help!!!!
Answer:
the answer would be y = 20x + 0.15s
Step-by-step explanation:
In this problem you would just plug in your facts. 20 would plug in for m, 15% would change to 0.15 then you would plug 0.15 into c.
The equation represents Emma's situation is y = 20x + 0.15s. The correct option is C.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The equation in the form y = mx + cs models Emma’s situation is
y = 20x + 0.15s
She makes $20 per hour, so for x hours, she makes 20x. The slope-intercept of the line y= mx+c
Where y coordinate, x- x co-ordinate
m=slope of the given line
C-y intercept.
She makes a 15% commission on the sales, s. 15% = 0.15,
So for the sales, she makes
15% * s = 0.15s.
The total she makes is 20x + 0.15s
y = 20x + 0.15s
The complete question is given below:-

Jason and his brother each have the equal probability of being randomly selected to wash dishes after dinner. Jason wants to simulate the probability that more than 4 evenings will go by without him having to wash the dishes after dinner. He decides to conduct a simulation by flipping a quarter, with heads representing an evening where he washes dishes after dinner and tails representing an evening of not doing dishes after dinner. He keeps flipping until he flips heads and records the number of flips that were needed. For example, if two flips are needed to get heads, this indicates that he washes dishes on the second evening. He repeats this 50 times and records the data on the table below Number of flips until getting heads: 1,2,3,4,5,6,7,8 frequency: 21,18,4,4,2,0,0,1 Based on the results of the simulation, what is the probability that more than 4 evenings will go by without Jason having to wash dishes after dinner? [blank] %
Answer:
The probability that more than 4 evenings will go by without Jason having to wash dishes after dinner is 0.06.
Step-by-step explanation:
We are given that Jason wants to simulate the probability that more than 4 evenings will go by without him having to wash the dishes after dinner.
He repeats this 50 times and records the data on the table below;
Number of flips until getting heads Frequency
1 21
2 18
3 4
4 4
5 2
6 0
7 0
8 1
Total 50
Now, we have to find the probability that more than 4 evenings will go by without Jason having to wash dishes after dinner.
This will happen only when the Number of flips until getting heads is 5, 6, 7 or 8 as only then Jason will have more than 4 evenings go by without washing dishes after dinner.
So, required probability = [tex]\frac{2}{50}+\frac{0}{50}+\frac{0}{50}+\frac{1}{50}[/tex]
= [tex]\frac{3}{50}[/tex] = 0.06
15−x+y=14−(−x−y) help plz
Answer:
[tex]x=0.5[/tex]
[tex]y=anything[/tex]
Step-by-step explanation:
15−x+y=14−(−x−y)
15-x+y=14+x+y
Subtract 14 from both sides
1-x+y=x+y
Subtract y from both sides
1-x=x
Add x to both sides
1=2x
2x=1
Divide both sides by 2
x=0.5

What is the factorization of 729x^15 + 1000?
729x¹⁵ + 1000
This is a case of a sum of cubes.
729 is the cube of 9
1000 is the cube of 10
x¹⁵ is the cube of x⁵
A sum of perfect cubes can be factored into
(a + b) (a² - ab + b²)
(9x⁵+ 10) ((9x⁵)²-(9x⁵)(10) + 10²)
(9x⁵ + 10) (81x¹⁰ - 90x⁵ + 100) THIS IS THE FACTORIZATION
9x⁵ (81x¹⁰ - 90x⁵ + 100) + 10(81x¹⁰ - 90x⁵ + 100)
729x¹⁵ - 810x¹⁰ + 900x⁵ + 810x¹⁰ - 900x⁵ + 1000
729x¹⁵ - 810x¹⁰ + 810x¹⁰ + 900x⁵ - 900x⁵ + 1000

Which is the equation for a sphere with the center (8,-6,6) and radius 6?
Answer:
(x - 8)² + (y+6)² + (z-6)²= 36
Step-by-step explanation:
To find the equation for a sphere with the center (8,-6,6) and radius 6, we will follow the steps below;
first write down the standard equation of a sphere:
(x - h)² + (y-k)² + (z-l)²= R²
where h, k and l are the center and R is the radius
From the question given, h = 8, k =-6 l=6 and R=6
we can now substitute the values into the formula
(x - h)² + (y-k)² + (z-l)²= R²
(x - 8)² + (y+6)² + (z-6)²= 6²
(x - 8)² + (y+6)² + (z-6)²= 36
Therefore, the equation for a sphere with the center (8,-6,6) and radius 6 is
(x - 8)² + (y+6)² + (z-6)²= 36

18. The equations 6x + 5y 300 and 3x + 7y = 285
represent the
money collected from selling gift
baskets in a school fundraising event. If x represents
the cost for each snack gift basket and y represents
the cost for each chocolate gift basket, what is the
cost for each chocolate gift basket?
A) $20 B) $25 C) $30 D) $54
PLS HELP ME ASAP!
Answer: The cost for each chocolate gift basket is b)$25.
Step-by-step explanation:
Hi, the correct equations are:
6x + 5y =300
3x + 7y = 285
So, if we multiply the second equation by 2, and subtract the first equation to the second equation:
6x +14 y= 570
-
6x +5y =300
_________
9y = 270
Solving for y:
y = 270/9
y = 30
Substituting y=30 on any equation:
6x + 5y =300
6x + 5(30) =300
Solving for x (cost for each chocolate gift basket)
6x+150 =300
6x =300-150
6x = 150
x =150/6
x = $25
The drama club is selling tickets to their play to raise money for the show's expenses.
Each student ticket sells for $4.50 and each adult ticket sells for $8. The auditorium
can hold no more than 84 people. The drama club must make at least $560 from
ticket sales to cover the show's costs. If 29 student tickets were sold, determine all
possible values for the number of adult tickets that the drama club must sell in order
to meet the show's expenses. Your answer should be a comma separated list of values.
If there are no possible solutions, submit an empty answer.
Answer:
The minimum number of adult tickets required to be sold = 54
Step-by-step explanation:
Hello,
In this question, we have several variables which might confuse us here, so I'll have to break it down bit by bit.
The drama club must make a sale of $560 so as to cover cost for the event.
The seat capacity of the hall = 84
Cost of tickets for adult = $8
Cost of tickets for students = $4.50
Total number of students sold = 29
Let the number of adult ticket required = x.
(4.50 × 29) + (8 × x) = 560
130.5 + 8x = 560
8x = 560 - 130.5
8x = 429.5
Divide both sides by 8
X = 429.5 / 8
X = 53.6 approximately 54.
Minimum required number of adult tickets to be sold is 54.
(29 × 4.50) + (54 × 8) = $130.5 + $432 = $562.5

{54,55}

Customers can pick their own apples at the Happy Apple Farm. They pay $5
to enter the farm and S2.50 per pound for the apples they pick. Write an
equation to model the total cost, y, for x pounds of apples.
O A. y = 5x + 25
B. y = x(2.5 + 5)
c. y = 2.5x + 5
O D. y = 2.5(x + 5)
Answer: C
Step-by-step explanation:
For this problem, we know that customers already have to pay $5 just to enter the farm. The $5 is basically a flat fee. Our equation would be:
y=5+____
Now, we know that the apples cost $2.50 per pound. Our final equaiton would be:
y=5+2.5x

Simplify i^12
A. -1
B. -i
C. i
D. 1
Answer:
D
Step-by-step explanation:
Answer:
D. 1.
Step-by-step explanation:
We know that the powers of the imaginary constant, i, follow a certain pattern.
i^1 = i, i^2 = -1, i^3 = -i, i^4 = 1.
Every 4 powers, the result cycles back to the original i. This is because there are only 4 unique digits that result from raising i to various powers.
To figure a higher power, such as 12, we need to take the remainder of the power when divided by 4 (the amount of unique answers), to simplify it to the original 4 powers.
So when you have i^12 power, the remainder is 0. This is because 4 is a factor of 12. As a result, we can simplify this to i^8, and therefore i^4, which equals 1.
I hope this helps!
