Hayden’s mom purchased a savings bond for Hayden. The value of this savings bond increases by 6% every year. One year after it was purchased, the value of the savings bond was $530. Find the value of the bond when Hayden’s mom purchased it. Explain your reasoning!
The new value would be the starting value x 1 + interest rate:
New value = starting value x 1.06
The new value is 530:
530 = starting value x 1.06
Find the starting value by dividing the new value by 1.06:
start value = 530/1.06
Start value = 500
Answer: $500.
explain reasoning: because the bond is only one year old you would multiply the value of the bond by the interest rate and add the interest amount to the bond to get $530.

Noah has collected $50 by selling lemonade and muffins. He sold $10 worth of muffins. He sold
each cup of lemonade for $2. How many cups of lemonade did he sell?
Answer:
5 cups of lemonade
Step-by-step:
Let's first make an equation from the question.
$10 = muffins (x)
$2 = cups of lemonade (y)
$10x + $2y = $50
x= 4
y= 5
Plug in the numbers:
$10(4) + $2(5) = $50
8x-2y = 18
y = 4x - 9
Solve by substitution
Answer:
Infinitely many solutionsStep-by-step explanation:
Given system:
8x - 2y = 18y = 4x - 9Solve by substitution:
8x - 2(4x - 9) = 188x - 8x + 18 = 1818 = 18We got correct equation without variables.
It means the equation is correct for any value of variables, the lines are same and overlap.
So there are infinitely many solutions.
order the numbers least to greatest.

The Smiths bought an apartment for $78,000. Assuming that the value of the apartment will increase in value 5% a year, how much will the apartment be worth in 6 years? Answer to the nearest penny.
The value of the apartment in 6 years is $104,527.46.
What is the future value of the apartment?The value of the apartment appreciates (increase in value) by 6% every year. The formula that can be used to determine the future value of the apartment is:
FV = P (1 + r)^n

Answer:
81.6 inches squared
Step-by-step explanation:
The formula for calculating all parallelograms is Area+=base*height.
The height is given to you, 6.8, the base of the figure is also given, 12.
Now all you have to do is to multiply.
That would get you to 81.6.
(When asked for area of parallelogram, the length of any line other than the height and base is not needed)

Answer:
see step-by-step below
Step-by-step explanation:
1) y - 2 > 3
Add 2 to both sides: y > 5
2) y ≤ 2
Draw a closed circle at y = 2 then shade the numbers to the left
3) y ≥ 250
where y = savings
4) The image isn't very clear, so I can't tell if it's a closed or open circle on -4.
If it is closed, it will be y ≤ -4
If it is open, it will be y < -4
5) -4 < f
Draw an open circle at f = -4 then shade the numbers to the right
6) x < -3.5
Draw an open circle at x = -3.5 then shade the numbers to the left
7) closed circle ... shade to the left of 8 ... make y equal to or less than 8.
8) F ≤ 6
C - closed circle at 6 with shaded numbers to the left

James is contemplating an investment opportunity represented by the function A(t)=P(1.06)t, where P is the initial amount of the investment, and t is the time in years. If James invests $5000, what is the average rate of change in dollars per year (rounded to the nearest dollar) between years 15 and 20?
Enter your answer as a number, like this: 42
Answer:
Rate of change per year = $5300
Step-by-step explanation:
Step 1: Substitute the variable P for the invested amount
1. A(t) = 5000(1.06)t
2. A(t) = (5300)t
Step 2: Substitute the variable t for the first 15 years
1. A(15) = (5300)(15)
2. A(15) = 79,500
Step 3: Substitute the variable t for the 20 years
1. A(20) = (5300)(20)
2. A(20) = 106,000
Step 4: Find your two ordered pairs and relation
First ordered pair: (15, 79,500)
Second ordered pair: (20, 106,000)
Relation: {(15, 79,500), (20, 106,000)}
Step 5: Find the slope or rate of change between 15 and 20 years
Let (y₁, x₁) = (15, 79,500)
Let (y₂, x₂) = (20, 106,000)
1. Use the slope expression: y₂ - y₁/x₂ - x₁
2. Substitute the correct values into the expression:
106,000 - 79,500/20 - 15
3. Simplify: 26500/5 = 5300
4. Hence, the rate of change in dollars per year is $5300

Answer:
PS = 7
SQ = 7.125
m<QTR = 115
m<TQR = 32.5
Step-by-step explanation:
To find PS, you need to take the measurement from QR [stated in the problem] which is 7 feet.
To find SQ, you need to take the measurement from RT [stated in the problem as 3 9/16] and then multiply it by 2 as SQ is 2 times longer than RT, which means SQ = 7 1/8 or 7.125 [since it needs to be a decimal]
To find m<QTR, you need to take the measurement from m<RTS, and since those 2 angles together equal 180, you need to subtract 65 degrees [from m<RTS] from 180, resulting in 115 degrees.
To find m<TQR, you need to know that a triangle has 180 degrees within it. Then you need to find one angle. We know the wider angle, <T = 115 degrees, so then we have to do 180 - 115, which equals 65 [that is the total for the 2 remaining equal corners], then we just have to divide by 2, which equals 32.5 degrees.

Given:
[tex]X = {0,1,2,3,4} \\ Y = {2,4,6,8,10,12} \\ Z = {3,6,9,12,15}[/tex]
So,
[tex]X∪Y = (0,1,2,3,4) \: ∪ \: (2,4,6,8,10,12) \\ = > (0,1,2,3,4,6,8,10,12)[/tex]
[tex]X∩Z = (0,1,2,3,4) \: ∩ \: (3,6,9,12,15) \\ = > (3)[/tex]
[tex](X∪Y)∩Z = (0,1,2,3,4,6,8,10,13) ∩ (3,6,9,12,15) \\ = > (3,6)[/tex]
Using the generic set operations, we will see that:
1) X U Y = {0, 1, 2, 3, 4, 6, 8, 10, 12}2) X ∩ Z = {3}3) Z = {3, 6, 9, 12, 15}How to operate with sets?
For two given sets A and B, we define:
A ∪ B as the union of the two sets, this is the set that contains all the elements from both A and B.
A ∩ B is the intersection of A and B, this set contains only the common elements of A and B.
Now we want to complete the given table:
1) X U Y is the union of sets X and Y (we do not repeat elements) so this is equal to:
{0, 1, 2, 3, 4, 6, 8, 10, 12}
2) X ∩ Z is the intersection of X and Z, the only common element between these sets is 3, then:
X ∩ Z = {3}
3) (X U Y)∩ Z
Is the set of the common elements between:
X U Y = {0, 1, 2, 3, 4, 6, 8, 10, 12}
Z = {3, 6, 9, 12, 15}
The common ones are:
3, 6, and 12, then we have:
(X U Y)∩ Z = {3, 6, 12}

A car wash detailed 144 cars in 4 hours. At what rate did the car wash detail cars in cars per hour?
Answer:
If this car wash took 4 hours to detail 144. 144/4 = 1/36 meaning that every hour they would detail 36 cars, we can double-check this and multiply 36 by 4 and we will get 144 meaning that this is true and that this car wash detailed 36 cars in an hour.
