Peyton received a graduation gift from his grandparents of $12,700. He
does not need the money for the first year of college. So he decided to
invest the money in a high interest savings account. If he puts all the
money in a high interest savings account paying 8.8% interest
compounded semiannually, how much money will be in the account at the
end of one year to use for college? *
Answer:
Peyton's account will have $13,842.18 after a year.
Step-by-step explanation:
Given that Peyton received $ 12,700 and decided to invest it for a year in an account that grants an interest of 8.8% per year, compounded semiannually, to determine the amount of money that will be in said account after the passage of one year, it is necessary to perform the following calculation:
X = 12,700 (1 + 0.088 / 2) ^ 1x2
X = 13,842.18
Therefore, after a year has passed, Peyton's account will be $ 13,842.18.

2) Fill in an angle measure greater than 100 degrees for the missing angle in yellow below. You will fill
this in at the top of the chart and base all other angles you calculate on this measure. Find all the
missing angle measure.
Answer:
m∠a = 110°
m∠b = 110°
m∠c = 70°
m∠d = 70°
m∠i = 110°
m∠h = 110°
m∠j = 70°
m∠g = 110°
m∠f = 70°
m∠e = 70°
m∠k = 57°
m∠m = 70°
m∠l = 167°
Step-by-step explanation:
Let the measure of the yellow angle = 110°
Therefore;
m∠a = 110° by vertically opposite angles
m∠b = m∠a = 110° by opposite interior angles of a parallelogram
m∠c = 180° - 110° = 70° by same side interior angles
m∠d = m∠c = 70° by opposite interior angles of a parallelogram
m∠i and m∠c are supplementary angles, therefore, m∠i = 110°
m∠h = m∠i = 110° by vertically opposite angles
m∠j = m∠c = 70° by vertically opposite angles
m∠g and m∠d are supplementary angles, therefore, m∠g = 110°
m∠f = m∠d = 70° by alternate interior angles
m∠f = m∠e = 70° by vertically opposite angles
m∠k = 180° - (m∠h + 13°) = 180° - (110° + 13°) = 57°
m∠b and m∠m are supplementary angles, therefore, m∠m = 70°
m∠l and 13° are supplementary angles, therefore, m∠l = 167°

What is the value of y?Exaplain what the coordinates repersent
Answer:
(1, 35) means that $35 is the cost per hour of hiring a face painter.
Step-by-step explanation:
Notice that this is a linear function that goes through the origin and also through the point (5, 175) which according to the data plotted in both axis, means that for 5 hours of service, the cost is $175.
One can calculate the slope of this line as that of the segment that joins (0, 0) with (5, 175) as:
slope = (175 - 0) / (5 - 0) = 175 / 5 = 35 / 1
Notice as well that such slope reads the amount of dollars to hire a face painter for ONE hour (so it is the rate per hour for hiring a face painter).
So the point (1 , y) should be completed as: (1, 35) and means "the rate per hour for hiring a face painter."

Answer:
Figure J does not show y as a function of x ⇒ D
Step-by-step explanation:
y is a function of x if and only if every x has only one value of y
Let us check each given figure if it shows a function or not
#Figure F
∵ Every value of x has an arrow is pointed to one value of y
∴ Every x has only one value of y
∴ The figure shows y as a function of x
#Figure G
∵ The ordered pairs have different values of x-coordinates
∴ Every x-coordinate has only one value of y-coordinate
∴ The figure shows y as a function of x
#Figure H
∵ Every x in the table appears once
∴ Every x has only one value of y
∴ The figure shows y as a function of x
#Figure J
∵ The ordered pairs were drawn in the figure are (-3, -2), (-3, -3), (-2, 0),
(-2, -1), (-1, 1), (-1, 2), (0, 3), (0, 4)
∵ x = -3 has two values of y, y = -2 and -3
∵ x = -2 has two values of y, y = 0 and -1
∵ x = -1 has two values of y, y = 1 and 2
∵ x = 0 has two values of y, y = 3 and 4
∴ Every x-coordinate has more than one value of y-coordinate
∴ Figure J does not show y as a function of x

Pauline invested $10,000 at two different
rates, 4% and 6%. If her total interest income
was $470, how much did she invest at each
rate?
Answer:
So for this, I will be doing a system of equations. Let x = money invested at 4% and y = money invested at 6%. We know that x and y will total up to 10k since that's how much he initially invested, so that'll be one of our equations.
Our other equation will represent the total balance he has after investing. We know that x's interest is 4% (since the money is increasing, this would translate to 1.04 in decimal form) and y's interest is 6% (aka 1.06 in decimal form since its increasing) and that the total balance is 10470 (initial balance + interest income).
Step-by-step explanation:
Using all this info, these are our two equations:
X+Y=10000
1.04x+1.06=10470
Next, substitute x in the second equation for (10000 - y) and solve for y as such:
1.04(10000-y) +1.06y =10470
10400 - 1.04y + 1.60y = 10470
10400 + 0.02y = 10470
0.02y =70
y = 3500
Now that we have the value of y, substitute it into either equation to solve for x:
x + 3500 = 10000
x= 6500
1.04x + 1.06(3500)= 10470
1.04x = 6500
Answer
In short:
$6,500 was invested in the 4% rate
$3,500 was invested in the 6% rate
A line segment AB has the coordinates A (2,3) AND B ( 8,11) answer the following questions (1) What is the slope of AB? (2) What is the length of AB? (3) What are the coordinates of the mid point of AB?(4) What is the slope of a line perpendicular to AB ?
Answer:
1. Slope: [tex]m = \frac{4}{3}[/tex]
2. Distance: [tex]AB = 10[/tex]
3. Midpoint: [tex]M = (5,7)[/tex]
4. Slope of perpendicular line: [tex]m_2 = -\frac{3}{4}[/tex]
Step-by-step explanation:
Given
[tex]A = (2,3)[/tex]
[tex]B = (8,11)[/tex]
Solving (1): Slope of AB
Slope (m) is calculated as follows:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where:
[tex]A = (2,3)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]B = (8,11)[/tex] --- [tex](x_2,y_2)[/tex]
So, we have:
[tex]m = \frac{11 - 3}{8 - 2}[/tex]
[tex]m = \frac{8}{6}[/tex]
[tex]m = \frac{4}{3}[/tex]
Solving (2): Length AB
This is solved by calculating the distance of AB using the following formula.
[tex]AB=\sqrt{(x_1-x_2)^2 + (y_1 - y_2)^2}[/tex]
Where:
[tex]A = (2,3)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]B = (8,11)[/tex] --- [tex](x_2,y_2)[/tex]
So:
[tex]AB = \sqrt{(2-8)^2 + (3 - 11)^2}[/tex]
[tex]AB = \sqrt{(-6)^2 + (-8)^2}[/tex]
[tex]AB = \sqrt{36 + 64}[/tex]
[tex]AB = \sqrt{100}[/tex]
[tex]AB = 10[/tex]
Solving (3): Midpoint of AB.
Midpoint, M is calculated as follows:
[tex]M = \frac{1}{2}(x_1+x_2, y_1 + y_2)[/tex]
Where
[tex]A = (2,3)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]B = (8,11)[/tex] --- [tex](x_2,y_2)[/tex]
So:
[tex]M = \frac{1}{2}(2+8,3+11)[/tex]
[tex]M = \frac{1}{2}(10,14)[/tex]
[tex]M = (5,7)[/tex]
Solving (4): Slope of line perpendicular to AB
The relationship between the slopes of two perpendicular lines is:
[tex]m_2 = -\frac{1}{m_1}[/tex]
Where
[tex]m_1[/tex] represents the slope of AB
[tex]m_1 = \frac{4}{3}[/tex]
So:
[tex]m_2 = -1/\frac{4}{3}[/tex]
[tex]m_2 = -1*\frac{3}{4}[/tex]
[tex]m_2 = -\frac{3}{4}[/tex]

Sam wants to build a fence around her property. The length of
the her fence must be one feet greater than three times its
width and the area of her property is 30 square feet. What is
the maximum width that her fence can be to ensure she
doesn't encroach into her neighbor's property?
Answer:
3.33ft
Step-by-step explanation:
Area of the fence = Length * Width
A = LW
Given
Area A = 30ft²
If the length of the her fence must be one feet greater than three times its width, then;
L = 3W + 1
Substotute into the area formula
A = (3W+1)W
30 = 3W²+W
3W²+W - 30 = 0
(3W²+9W)-(10W - 30) =
3W(W+3)-10(W+3) = 0
3W-10 = 0 and W+3 = 0
3W = 10 and W = -3
W = 10/3 and -3
Width cannot be negative
Hence the maximum width that her fence can be to ensure she doesn't encroach into her neighbor's property is 3.33ft
Eli wanted to order candy online. Company A is offering 2 1/2 pounds of chocolate for $32.00. How much is Company A charging per pound of chocolate?
Answer:
Therefore, Company B is offering the lowest price/lb at $12.73/lb.
So, Company A's price / lb = ($32.50/2.5lbs) = $13.00/lb
Step-by-step explanation:
To determine price per lb, divide dollar amount by lbs.
- Company A sells 2 1/2lbs (2.5lbs) for $32.50
- Company B sells 2 3/4lbs (2.75lbs) for $35.00
And, Company B's price / lb = ($35.00/2.75lbs) = $12.73/lb
A concert ticket costs $23. About how much will tickets costs for a group of 22 people?
Answer:
$506
Step-by-step explanation:
We know that 1 concert ticket is $23
Multiply 23 by 22 to get 506
They spend $506 in total for the tickets.
The total cost for a group of 22 people is $506 if a concert ticket costs $23. , the answer is $506.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A concert ticket costs $23.
Let x be the total cost for the group of 22 people:
The value of x can be found as follows:
The linear equation in one variable:
x = 23×22
x = $506
Thus, the total cost for a group of 22 people is $506 if a concert ticket costs $23. , the answer is $506.

When comparing a single sample to a population mean, a one sample t test must be used instead of a one sample z test when what value is unknown?
a. The sample mean
b. The population standard deviation
c. The desired alpha level
d. The sample standard deviation
e. The sample variance
Answer: b. The population standard deviation
Step-by-step explanation:
The one-sample z-test is a test that us carried out to ascertain whether the mean of a population is either greater or less than a specific value given.
The one sample t test is used in comparing the mean of the sample data of the researcher carrying out the research to a known value.
When the population standard deviation is known, the one sample z test is used while when the population standard deviation is not known, one can use the one sample t test.
