Explanation:
To find the value of the account, we use the compound interest formula below:
[tex]Amount\: at\: Compound\: Interest,A=P(1+\frac{r}{n})^{nt}[/tex]From the given information:
• Principal,P=$4500
,• Interest Rate, r=4.5%=0.045
,• Number of compounding periods, n=12 (Monthly)
,• Time, t=4.5 years
Substituting the given values, we have:
[tex]\begin{gathered} A=4500(1+\frac{0.045}{12})^{12\times4.5} \\ =4500(1+0.00375)^{54} \\ =4500(1.00375)^{54} \\ =\$5507.98 \end{gathered}[/tex]The value of the account when the customer takes the money at the end of the 4.5 years is $5507.98.
Luna purchased a computer at the list price of ₱56,000, less 30% and 20%. How much must Luna pay for the computer?
There are two disccount applied to this computer, the first one is 30%. To calculate its value, we need to multiply the original price by the fraction that represents 30%
[tex]\text{discount}1=56000\cdot\frac{30}{100}=16800[/tex]The first discount was 16,800. To determine the price after this, we need to subtract the listed price by the discount 1, this is done below:
[tex]\text{price}2=56000-16800=39200[/tex]Then we need to calculate the second discount, which was equal to 20%.
[tex]\begin{gathered} \text{discount}2=39200\cdot\frac{20}{100}=7840 \\ \end{gathered}[/tex]The final price is the subtraction between the price 2 and the discount 2, we have:

Part B: The regular-sized box of cereal costs $4.29. How much does 1 breakfast from a regular-sized box of cereal cost Greg? Round to the nearest hundredth. Show all work.
Part C: If Greg purchased the family-sized box of cereal that contains 18 servings, how many more breakfasts could Greg eat from 1 box? Show all work.
a. Greg can eat 8 breakfasts from 1 box.
b. The cost of 1 breakfast from a regular-sized box is $34.32.
c. Greg will enjoy 4 breakfast more.
How to calculate the fraction?a. A regular-sized box contains 12 servings. If Greg eats 1 1/2 servings for breakfast every day, the number of breakfasts that Greg can eat from 1 box will be:
= 12 ÷ 1 1/2
= 12 ÷ 1.5
= 8
b. Since the regular-sized box of cereal costs $4.29. The cost of 1 breakfast from a regular-sized box of cereal cost Greg will be:
= 8 × $4.29
= $34.32
c. If Greg purchased the family-sized box of cereal that contains 18 servings, the number of breakfasts will be:
= 18 ÷ 1.5
= 12 breakfast
The difference will be:
= 12 - 8
= 4 breakfast more.

The equation of the line that passes through the points ( -3,18 ) and ( 2,-7 ) is f(x) = -5x + 3.
What is the equation of line passing through the given points?The formula for equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
Given the data in the question;
Point 1( -3,18 )
x₁ = -3y₁ = 18Point 2( 2, -7 )
x₂ = 2y₂ = -7First, we find the slope of the line.
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
m = ( -7 - 18 ) / ( 2 - (-3) )
m = ( -25 ) / ( 2 + 3 )
m = ( -25 ) / ( 5 )
m = -5
Next, next we find the y-intercept
y = mx + b
18 = (-5)(-3) + b
18 = 15 + b
b = 18 - 15
b = 3
Now that the values of slope m and y-intercept b is known, plug these into y = mx + b to determine the equation of the line.
y = mx + b
y = (-5)x + 3
y = -5x + 3
Therefore, the equation of the line is y = -5x + 3

A lab assistant needs to create a 500 mL mixture that is 5% hydrochloric acid. The assistance has solutions of 3.5% and 6% in supply at the lab. Using the variables x and y to represent the number of milliliters of the 3.5% solution and the number of milliliters of the 6% solution respectively, determine a system of equations that describes the situation. Enter the equations below separated by a comma.How many milliliters of the 3.5% solution should be used? How many milliliters of the 6% solution should be used?
Let
x -----> the number of milliliters of the 3.5% solution
y ----> the number of milliliters of the 6% solution
we have that
3.5%=3.5/100=0.035
6%=6/100=0.06
5%=5/100=0.05
so
0.035x+0.06y=0.05(500) -------> equation A
and
x+y=500 -----> x=500-y ------> equation B
solve the system of equations
substitute equation B in equation A
0.035(500-y)+0.06y=0.05(500)
solve for y
17.5-0.035y+0.06y=25
0.025y=25-17.5
0.025y=7.5
y=300
Find out the value of x
x=500-300=200

The value of g(x) will be expressed as g(x) = (x + 5)
A function may be defined as an expression in which for one value of input variable x there is only one value of output variable y. The input variable is called as independent variable and output variable is called dependent variable. Composite functions are the functions which are written as combination of two functions. A function f(x) may be defined as composite function of another function g(x) when it can be written as either f(g(x)) or g(f(x)). We know that f(x) = x⁹ and the composite function H(x) = f(g(x)) = (x + 5)⁹. So, from this we can say that the function g(x) will be given as (x + 50 as we put (x + 5) as x in the function H(x).

SlopeThe slope of the line through points (x1, y1) and (x2, y2) is given by the formula ...
m = (y2 -y1)/(x2 -x1)
For the given points, the slope of the line is ...
m = (-2 -(-9))/(0 -8) = -7/8
InterceptThe y-intercept of the line is the y-value when x = 0. The point (0, -2) tells you the y-intercept is -2.
EquationThe slope-intercept equation is ...
y = mx +b . . . . . . where m is the slope, and b is the y-intercept
For a slope of -7/8 and a y-intercept of -2, the equation is ...
y = -7/8x -2
Felix is making a pattern with tiles shaped like parallelograms. He needs 5 black tiles
and 5 white tiles. The tiles cost $0.50 per cm².
What is the total area of the tiles Felix needs
to buy?
Answer: 80
Step-by-step explanation:
You do 2 times= 8 and multiply 8 to the 5 white and black tiles which equals 40+40=80.
The total area for the parallelogram shaped tiles Felix needs to buy is 80cm² at the price of $40.
Area of parallelogramIn calculating for the area of parallelogram, the base is multiplied by the height, as the same way for calculating the area of a rectangle.
Given that, the base of one parallelogram shaped tile is 4cm with height as 2cm.
Area of one parallelogram shaped tile = 4cm × 2cm
Area of one parallelogram shaped tile = 8cm²
Total area for the 5black and 5white tiles = 10 × 8cm²
Total area for the 5black and 5white tiles = 80cm²
Therefore, Felix needs to buy a total of 80cm² of 10 parallelogram shaped tiles.

[tex]\begin{gathered} m\colon\text{ slope} \\ c\colon\text{ y-intercept} \end{gathered}[/tex]To graph any straight line we need the equation of the straight line or atleast two points that must lie on the line.
We are given the slope ( m ) and one of the points that lie on the line as follows:
[tex]\begin{gathered} m\text{ = -}\frac{2}{5} \\ \\ (\text{ -3 , 5 )} \end{gathered}[/tex]We need one another point that lies on the line to plot the graph of a straight line. To find another point we must completely express the equation of the straight line ( general form given above ).
