Answer:
Anything that does not cost more than $2,560.00
Step-by-step explanation:
Provided that Nikita is spending money that she had invested and the amount she collected over the period of 7 years. She can buy any item that costs no more than $2,560.00 but how?
It is a problem of simple interest:
Here the principal amount (P) = $2,000.00
Interest rate (r) = 4%
Time period (t) = 7 years
So, total amount that she would get by the end of 7 years is:
[tex]A=P+SI[/tex]
[tex]SI=\frac{P\times r\times t}{100}[/tex]
Plugging the values we get:
[tex]SI=\frac{2000\times 4\times 7}{100}=560.00[/tex]
So the interest collected over 7 years is $560.00
Therefore, the total amount after 7 years is:
[tex]\$2000.00+\$560.00=\$2,560.00[/tex]
If Nikita is using this money then the most expensive item that she could buy will cost no more than $2,560.00.

Write an equation of the parabola in intercept form with x-intercepts of 12 and -6; and an axis of symmetry of (14, 4).
Please show work!
Intercept form is: y = a(x - p)(x - q)
It is given that: p = 14, q = -6, x = 14, y = 4
4 = a(14 - 12)(14 - (-6))
4 = a(2)(20)
4 = 40a
[tex]\frac{4}{40} = \frac{40a}{40}[/tex]
[tex]\frac{1}{10} = a[/tex]
Answer: y = [tex]\frac{1}{10}[/tex](x - 14)(x + 6)
a toy company spends $20 for every doll it makes. Promotion of the dolls costs $400 and the company sells each doll for $30. How many dolls must the company sell to make a profit?
What inequality represents this problem?
The toy company must sell more than 40 dolls to make a profit, taking into account the production cost of $20 per doll, a fixed promotion cost of $400, and a selling price of $30 per doll. The inequality that represents this problem is x > 40, where x is the number of dolls sold.
Explanation:To determine how many dolls a toy company must sell to make a profit, we consider the cost of making each doll, the promotion cost, and the selling price per doll.
The company spends $20 to make each doll and has a fixed promotion cost of $400.
Each doll sells for $30.
The inequality representing the situation is:
30x - (20x + 400) > 0
Where x is the number of dolls sold. To find the breakeven point:
Calculate total cost: Total cost is the sum of the production cost for each doll and the promotion cost. If x is the number of dolls, then the total cost is 20x + 400.
Calculate total revenue: This is the selling price multiplied by the number of dolls, or 30x.
Set total revenue greater than total cost to find the breakeven point: 30x > 20x + 400.
Subtract 20x from both sides: 10x > 400.
Divide both sides by 10: x > 40.
The company must sell more than 40 dolls to make a profit. Thus, the inequality that represents this problem is x > 40.
Final answer:
The toy company must sell more than 40 dolls to make a profit. The cost of producing each doll is $20, and they are sold for $30 each, with a fixed promotional cost of $400. The inequality representing the situation is 30x > 20x + 400, where x is the number of dolls sold.
Explanation:
The question asks about the number of dolls a toy company must sell to make a profit. To calculate this, we must establish the costs and revenues involved in the production and sale of the dolls. The cost per doll is $20 and there is an additional fixed promotional cost of $400. Each doll is sold for $30.
Let's denote the number of dolls sold as x. The total cost for x dolls would be $20x (variable cost) plus $400 (fixed cost). The total revenue from selling x dolls would be $30x. To make a profit, the total revenue must be greater than the total costs.
Using this information, we can write the inequality for profit as follows:
Total Revenue > Total Cost
$30x > $20x + $400
To find the breakeven point where the company begins to make a profit, we must solve for x:
$10x > $400
x > 40
So, the company needs to sell more than 40 dolls to start making a profit.
Juan ordered 20 pizzas for a party. 45% of the pizzas have 8 slices each. The remaining 55% of the pizzas have 12 slices each. Complete the model. Then complete the statements to find the total number of slices of pizza.
Total number of pizzas Juan ordered [tex]20[/tex]
Since, [tex]45\%[/tex] of pizzas have [tex]8[/tex] slices.
Therefore, number of pizzas with [tex]8[/tex] slices are: [tex]45\%\times(20)[/tex]
[tex]=\frac{45}{100} \times(20)[/tex]
[tex]=\frac{45}{10} \times(2)[/tex]
[tex]=\frac{90}{10}[/tex]
[tex]=9[/tex] pizzas
Also, since, [tex]55\%[/tex] of pizzas have [tex]12[/tex] slices.
Therefore, number of pizzas with [tex]12[/tex] slices are: [tex]55\%\times(20)[/tex]
[tex]=\frac{55}{100} \times(20)[/tex]
[tex]=\frac{55}{10} \times(2)[/tex]
[tex]=\frac{110}{10}[/tex]
[tex]=11[/tex] pizzas
Now, there are [tex]9[/tex] pizzas with [tex]8[/tex] slices and [tex]11[/tex] pizzas with [tex]12[/tex] slices.
Therefore, total number of slices of pizza are: [tex]=(9)(8)+(11)(12)[/tex]
[tex]=72+132[/tex]
[tex]=204[/tex] slices
Answer:
I hope this helped! <3
Step-by-step explanation:
Number of pizzas with 8 slices: 9
Number of pizzas with 12 slices: 11
45% of the pizzas have 8 slices each. In total, there are 72 slices in these pizzas.
55% of the pizzas have 12 slices each. In total, there are 132 slices in these pizzas.
Altogether, there is a total of 204 slices of pizza.
Let a=3/4 and b=1/5. If a*x=b, then what is x?
In general, any equation like [tex] ax=b [/tex] (assuming [tex] a \neq 0[/tex]) is solved by
[tex] x= \dfrac{b}{a} [/tex]
So, in your case, the solution is
[tex] x = \dfrac{\frac{1}{5}}{\frac{3}{4}} [/tex]
Dividing by a fraction means to multiply by the inverse of that fraction:
[tex] \dfrac{\frac{1}{5}}{\frac{3}{4}} = \dfrac{1}{5} \cdot \dfrac{4}{3} = \dfrac{4}{15} [/tex]

A salesman keeps 20%of his sales as a commision. How much does he have to sell to earn $1000
The salesman needs to sell $5000 worth of products or services to earn a $1000 commission, calculated by dividing the desired commission by the percentage of commission he retains from sales.
To find out how much a salesman needs to sell to earn $1000 as a commission, we need to consider that he keeps 20% of his sales as commission. Since 20% is the part of the sales that corresponds to the commission, we can set up the following equation: 0.20 x sales = $1000.
To solve for sales, we divide both sides of the equation by 0.20:
sales = $1000 / 0.20
sales = $5000
Therefore, the salesman must sell $5000 worth of products or services to earn a $1000 commission.
Hey can you help with this please!?!?!
For this one, there are a few steps that will make it easier towards the end.
First lets solve for y
y+3x=8
subtract 3x from both sides
y=-3x+8
Now you are ready to plug in each of the x values and solve for y.
x vaues: -1, 0, 3
Here is what it would look like for each:
y=-3(-1)+8
y=3+8
y=11
y=-3(0)+8
y=8
y=-3(3)+8
y= -9+8
y=-1
So your final answer would be y= {-1, 8, 11}

Solve the equation.
x2 + 10x + 24 = 0
A) -12 and 2
B) 12 and -2
C) -4 and -6
D) 4 and 6
Answer:
Option C
Step-by-step explanation:
Given a quadratic equation
x^2+10x+24 =0
We can use either formula or factorization method to solve this equation.
The last term is 24, it is a product of 6 and 4. Sum =6+4 =10
Hence factoring can be done easier
Split the middle term as 6x +4x
x^2+6x+4x+24 =0
x(x+6)+4(x+6)=0
(x+4)(x+6)=0
Either x+4 =0 or x+6 =0
x=-6 or x =-4
Thus solution for this equation is option C

A cable company had 260 subscibers.The ratio of regular subscribers to premium subscribers was 10:3.How many regular subscribers did they have
Final answer:
The cable company had approximately 866.67 regular subscribers.
Explanation:
To find the number of regular subscribers, we need to set up a proportion using the given ratio. The ratio of regular subscribers to premium subscribers is 10:3, which can be written as 10/3. Let x represent the number of regular subscribers.
We can set up the proportion:
10/3 = x/260
Cross-multiplying, we get:
3x = 260 * 10
3x = 2600
Dividing both sides by 3, we find:
x = 2600 / 3
Therefore, the cable company had approximately 866.67 regular subscribers.

A square technology chip has an area of 25 square centimeters how long is each side of the chip
ANSWER
Each side of the chip is 5 centimeters long.
EXPLANATION
The chip is in the form of a square.
The formula for finding the area of a square is
[tex]Area=l^2[/tex]
We were given in the question that, the area is 25 square centimeters. This means that,
[tex]25=l^2[/tex]
We take the square root of both sides to get,
[tex]\sqrt{25}=l[/tex]
[tex]\Rightarrow 5=l[/tex]
Hence the length of the square technology chip is 5 centimeters
Which formula can be used to describe the sequence?
The formula that can be used to describe the sequence is:
[tex]f(x)=-3\cdot (\dfrac{-1}{5})^{x-1}[/tex]
Step-by-step explanation:We are given a sequence of numbers as:
[tex]-3\ ,\ \dfrac{3}{5}\ ,\ \dfrac{-3}{25}\ ,\ \dfrac{3}{125}\ ,\ \dfrac{-3}{625}[/tex]
Hence, we could observe that the series is a series with alternating sign such that the power of 5 is increasing in the denominator and there is no change in the numerator i.e. the power of 3 remain unchanged.
Hence,third and last option are discarded.
Also, in first option each of the terms of the digit will be negative and not alternating and hence option (1) is also discarded.
Hence, the function that represent this sequence is:
[tex]f(x)=-3\cdot (\dfrac{-1}{5})^{x-1}[/tex]
Which statement is true about the parts of this expression?
7.5y - z/9 + 50 +2ya) the constant is 7.5.B) the coefficients are 7.5 and -9.C) the variables are x and y.D) the like terms are 7.5y and 2y.
7.5y - z/9 + 50 + 2y
Okay, so it would be best to organize and simplify this expression: 9.5y -z/9 + 50
Alright, now let's eliminate some answers.
True or false: The constant is 7.5. This is false. 7.5 is a coefficient, 50 is a constant.
True or false: The coefficients are 7.5 and -9. This is false. Sure, 7.5 is a coefficient, but -9 is not. Actually, z/9 is also equal to (1/9)z, so technically 1/9 is the coefficient.
True or false: The variables are x and y. This is false. Where is x? Nonexistent.
True or false: The like terms are 7.5y and 2y. This is true. When we simplified the equation, we first combined like terms. 7.5y and 2y are like terms and therefore able to be combined. That's how we got 9.5y.
The answer, I believe, is D. Hope this helps!
