Answer:
$9629.63
Step-by-step explanation:
I assume this is simple interest.
The formula for simple interest is
F = P(rt + 1)
where F = future value,
P = present value
r = annual interest rate
t = number of years
10,400 = P(0.02 × 4 + 1)
10,400 = 1.08P
10,400/1.08 = P
9,629.63 = P
Answer: $9629.63

A certain shade of blue paint is made by mixing 1/2 of a quart of blue paint with 1/8 of a quart of white paint.
How much white paint would you need to mix with 2 2/3 quarts of blue paint to make the same shade of paint?
Explain the error.
Calculate the correct solution.
Answer:
Step-by-step explanation:
2 2/9? maybe because 1/8 is 6 times bigger than 1/2, so if you add 6 to 2 2/3 it would be 2 2/9?
You would need 1/4 white paint to mix with 2 2/3 quarts of blue paint to make the same shade of paint.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
The amounts of each type of paint as fractions of the total amount of paint: 1/2 quart of blue paint is 1/(1+1/2) = 2/4 = 1/2 of the total amount of paint, and 1/8 quart of white paint is 1/(1+1/2+1/8) = 1/8 of the total amount of paint.
So the ratio of blue paint to white paint in the original mixture is 1/2 to 1/8, or 4 to 1. To make the same shade of paint with 2 2/3 quarts of blue paint, we need to use the same ratio of blue paint to white paint.
So we need 1/4 as much white paint as blue paint, which is (1/4) × 2 2/3 quarts = 2/3 quart of white paint.
The error in the original solution was not correctly finding the ratio of blue paint to white paint in the original mixture, which is necessary to determine the correct amount of white paint to mix with a different amount of blue paint to create the same shade.

A square field has an area 625cm. Find the length of one of side.
Answer: 25cm
Step-by-step explanation:
Since the field is square we can understand each side is an equal length
This means we just have to use the formula...
[tex]A^2 = 625[/tex]
[tex]\sqrt{a^2} = \sqrt{625}[/tex]
a = ±25
Since it is a real thing, we are only looking at positive values, therefore your answer is

What is Linear equation in one variable?
A linear equation is an equation of a straight line, written in one variable. The only power of the variable is 1. Linear equations in one variable may take the form ax+ b = 0.
The given equation is:− 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) .
= -3x+18 + 12 x -8x-3
=x +15
The corresponding equation to the above equation is:
C. x+15
D. (12 x - 11x) + (3-18)
= x-15
E. (12 x - 11x) + (18-3)
= x+15
F. (12 x - 11x) + (-6+3)
= x-3
As from the above it can be seen that the equation which equivalent to given expression − 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) . is
x+15( 12 x − 11 x ) + ( 18 − 3 )Learn more about linear equation in one variable here:

Step-by-step explanation:
- on the number line, each small mark represents 1/6 so to make it easier I made the fraction into 1/6 form
- a coefficent is a numerical value placed before and multiplying the variable in an algebraic expression (ex. 4x)
In this case 7 is before the m making 7 the coefficent

Sean is building nesting boxes for their Etsy store. The smallest box is a cube, 10 cm on a side. It fits entirely inside a larger cubic box that is 15.0 cm on a side (50% larger). If each box has dimensions that are 50% larger than the one before then what is the total maximum number of nesting boxes Sean can build that will fit inside a shipping carton that has a cube-shaped interior, 1 m (100 cm) on a side?
Answer:
19
Step-by-step explanation:
I don't really have explanation but imagine putting boxes into boxes that are always a little bigger(+5 cm)
so you go from the smallest one 10cm and gradually keep adding 5cm until you reach 100cm.

The circumference of a circle is 25 pi cm . what is the area, in square centimeters? express your answer in terms of pi .
The area of the circle is the amount of space it occupies, and the area of the circle is 156.25π
How to determine the area?The circumference, C is given as:
C = 25π
Start by calculating the radius using:
C = 2πr
So, we have:
2πr = 25π
Solve for r
r = 12.5
The area is then calculated using:
A = πr²
So, we have:
A = π * 12.5²
Evaluate
A = 156.25π
Hence, the area of the circle is 156.25π

Answer:
[tex]\textsf{a)} \quad y=(x+1)^2-4[/tex]
[tex]\textsf{b)} \quad y=2(x-4)^2-2[/tex]
Step-by-step explanation:
Vertex form of a parabola: [tex]y=a(x-h)^2+k[/tex]
(where (h, k) is the vertex and [tex]a[/tex] is some constant)
Part aVertex = (-1, -4)Point on parabola = (1, 0)Substitute the vertex into the formula:
[tex]\begin{aligned}\implies y &=a(x-(-1))^2-4\\y & =a(x+1)^2-4\end{aligned}[/tex]
Substitute the point (1, 0) into the formula:
[tex]\begin{aligned}\implies a(1+1)^2-4&=0\\4a-4&=0\\4a &=4\\a &=1\end{aligned}[/tex]
Therefore, the equation of the parabola in vertex form is:
[tex]y=(x+1)^2-4[/tex]
Part bVertex = (4, -2)Point on parabola = (6, 6)Substitute the vertex into the formula:
[tex]\begin{aligned}\implies y &=a(x-4)^2+(-2)\\y & =a(x-4)^2-2\end{aligned}[/tex]
Substitute the point (6, 6) into the formula:
[tex]\begin{aligned}\implies a(6-4)^2-2&=6\\4a-2 & =6\\4a &=8\\a &=2\end{aligned}[/tex]
Therefore, the equation of the parabola in vertex form is:
[tex]y=2(x-4)^2-2[/tex]
Find a
a(x-h)²+k=ya(1+1)²-4=04a-4=04a=4a=1So

The results of this survey may be affected by nonresponse blas.
The results of this survey cannot be trusted because of convenience response bias.
O Bocauso random sampling is used, wo can fool confident that the porcont of all homo-schooled students who say they favor learning at home is close to 39%.
O Because more than half of those who were mailed the survey actually responded, va can feel fairly confident that the actual percentage of all home-schooled
students who prefer to learn at homo is close to 39%.
In this survey, the results can be trusted because more than half of the people responded which makes this sample to be representative.
What is nonresponse bias?This occurs when most of the people who were intended to be surveyed do not respond, which causes the results to be biased as the sample does not represent the population.
