a. How much will be in the account after 4 years?
b. How much will be in the account after 17 years?
c. How many years will it take for the account to contain $2,500?
d. How many years will it take for the account to contain $3,000?
a. After 4 years, the amount in the account will be $
(Do not round until the final answer. Then round to the nearest cent as needed.)
Answer:
a. $ 2,431.01 = 4 years
b. $ 4,584.04 = 17 years
c. 4.57 years = $ 2,499.57
d. 8.3 year = $ 2,998.48
e. $ 2,431.01 = 4 years
Step-by-step explanation:
Compound Interest Equation
A = P(1 + r/n)nt
Where:
A = Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
R = Annual Nominal Interest Rate in percent
r = Annual Nominal Interest Rate as a decimal
r = R/100
t = Time Involved in years, 0.5 years is calculated as 6 months, etc.
n = number of compounding periods per unit t; at the END of each period
Melissa made three batches of oatmeal cookies. Her recipe calls for amounts of sugar (in cups) and flour (in cups) in the following ratios.
What is the unit rate of change of flour (y) with respect to sugar (x)? That is, how much flour corresponds to one cup of sugar?
The unit rate of change is?
Graph the proportional relationship described above, with the x-coordinate representing cups of sugar, and the Y-coordinate representing cups of flour.
PLEASEEEEEE
the answer is 11/4
The unit rate of change between variables is the quotient between the difference between y-values and the difference between x-values
The unit rate of change is y = 2.25x
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the values of x be set A = { 2 , 3 , 4 }
Let the values of y be set B = { 4 1/2 , 6 3/4 , 9 }
So , the unit rate of change can be calculated by slope and linear equation of line
So , Slope m is
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
m = ( 6 3/4 - 4 1/2 ) / ( 3 - 2 )
m = 2.25
So , the equation will be y = mx
y = 2.25x
Therefore , the unit rate of change is y = 2.25x
Hence ,
The unit rate of change is y = 2.25x and the graph is shown below

600 feet of fence surround a rectangular playground that is 100 feet wide. How long is the playground? A.400 b.500 c.300 d.200
Answer:
A.400
Step-by-step explanation:
Well perimeter for a rectangle is l+l+w+w
100+100+l+l=600
200+2l=600
Subtract 200 from both sides
2l=400
Divide both sides by 2
l = 400 feet
The length of the rectangle is 400 feet long.

Answer:
Step-by-step explanation:
the answer is c
The statement must be true about parallelogram ABCD is BE ≅ DE option (C) BE ≅ DE is correct because the diagonals of a parallelogram bisect each other.
What is a Parallelogram?A parallelogram is a polygon with four sides, opposite sides of the parallelogram are parallel.
The parallelogram ABCD is shown in the figure.
A parallelogram is a type of quadrilateral,
The quadrilateral can be defined as the four-sided polygon in geometry having four edges and four corners.
The parallelogram has two diagonals, AC and BD.
From the property of Parallelogram,
The diagonals of a parallelogram bisect each other.
So, AC and BD bisect each other.
AE = ECBE = CE
The correct answer is BE ≅ DE.

A painter is painting a rectangular wall that measures 22.8 ft by 17.3 ft. Each gallon can of paint covers 100 square feet. What are the fewest gallons needed to paint the wall?
____gallons
Answer:
1.548 gallons
Step-by-step explanation:
Length of the rectangular wall = 25.1 ft.
Width of the rectangular wall = 18.5 ft.
Area of the rectangular wall = length * width = 25.1 * 18.5
= 464.35 square feet
300 square feet wall can be painted using 1 gallon of paint.
=> 1 square feet wall can be painted using gallon of paint.
=> 464.35 square feet wall can be painted using gallon of paint.
= 1.548 gallons of paint
Answer:
4 gallons
Step-by-step explanation:
The first thing you want to do is times 22.8 * 17.3 = 394.44. Then what you want to do is see how much 100 square gallons can cover the area : 4. If we make it 3 it is going under if it is 4 it can cover the whole thing, and if we make it 5 we have a little much.

Points P and Q belong to AB. If AB = a and AP = 2PQ = 2QB, find the distance between: the midpoints of AP and QB.
NO explanation needed. I need this fast
Answer:
The distance between midpoint of AP and QB is [tex]\frac{5a}{8}[/tex].
Step-by-step explanation:
Given that: AB = a
AP = 2PQ = 2QB
Thus,
PQ = QB = [tex]\frac{a}{4}[/tex]
PQ + QB = [tex]\frac{a}{4}[/tex]+ [tex]\frac{a}{4}[/tex]
= [tex]\frac{a}{2}[/tex]
AP = [tex]\frac{1}{2}[/tex] a = [tex]\frac{a}{2}[/tex]
The distance between midpoint of AP and QB can be determined as;
[tex]\frac{AP}{2}[/tex] + PQ + [tex]\frac{QB}{2}[/tex]
= [tex]\frac{a}{4}[/tex] + [tex]\frac{a}{4}[/tex] + [tex]\frac{a}{8}[/tex]
= [tex]\frac{2a+2a+a}{8}[/tex]
= [tex]\frac{5a}{8}[/tex]
Therefore, the distance between midpoint of AP and QB is [tex]\frac{5a}{8}[/tex].

The table shows to linear functions in the function values for different values of X. Which expression represents H(x)?
Answer:
(g + f)(x)
Step-by-step explanation:
the outputs of f(x) and g(x) will always have a sum of -1, which is h(x).
The expression of function H (x) is (g + f) (x).
Option 2 is true.
Here,
The function f (x) = -x - 4 and g(x) = x + 3
The value of H (x) is in the table is -1.
We have to find the expression to represents H(x).
What is Linear function?
A linear function is a simple function usually composed of constants and simple variables without exponents.
Now,
The function f (x) = -x - 4 and g(x) = x + 3
⇒( f + g ) (x) = f (x) + g(x)
= -x - 4 + x + 3
= -1
Which is same as the value of H (x) is in the table.
Hence, The expression of function H (x) is (g + f) (x).
Option 2 is true.
