Suppose that when your friend was born, your friend's parents deposited $9000 in an account paying 6.9% interest compounded . What will the account balance be after 17 years?
Answer:
the account balance after 17 years is $27,981.02
Step-by-step explanation:
Given that
The deposited amount i.e. $9,000
The Rate of interest is 6.9%
Time period = 17 years
We need to find out the account balance after 17 years
As we know that
Future value = Present value × (1 + rate of interest)^time period
= $9,000 × (1 + 6.9%)^17
= $27,981.02
Hence, the account balance after 17 years is $27,981.02
Which measurement is equivalent to 84 inches?
A.8 feet
B. 1 yard, 2 feet, 24 inches
C. 7 feet, 4 inches
D. 4 feet, 40 inches
Answer: A
Step-by-step explanation:
Answer: B. 1 yard, 2 feet, 24 inches
Step-by-step explanation: 1 yard is 36 inches. Each feet is 12 inches, but there are 2 feet so 12 times 2 is 24 inches. And the last is just 24 inches. So, 36 + 24 + 24 = 84 inches

100 POINTS!!! SHOW ALL WORK PLZ!!! Tarah bought 42 shares of a company’s stock for $16.45 / share. She pays a broker a commission of $7 to buy and
sell stock. After one year, Tarah sold all her shares, when they were worth $20.64 / share.
How much did it cost Tarah to buy the stock? Show your work.
What was Tarah’s net gain or loss? Show your work.
What was Tarah’s annual rate of return? Show your work, make answer a % and then round to tenths place.
Answer:
`a) $697.90
b) $161.98 gain
c) 23.2096% annual return rate
Step-by-step explanation:
a) $16.45 for one share. 42 shares will cost 16.45 x 42 = $690.90
As she used a broker and paid $7, the total cost for Tarah would be $697.90
b) After the investment, Tarah's gain is $20.64 per stock and she had bought 42. So the total income would be 20.64 x 42 = $866.88. However, she used a broker to sell the stocks as well, so the total gain would only be 859.88.
Overall, the cost was -697.90+859.88 = 161.98 net gain.
c) The rate of return would be the percentage of the original price of stocks that is equal to the net gain. What we are trying to find here is:
What percentage of 697.90 is 161.98?
We can find this percentage by doing a simple division (161.98/697.90) which gives us an answer of 0.232096
In percentages, multiply this decimal by 100 to get a 23.2096% annual return.

A wooden board is leaning against a wall. The base of the board is 10 feet from the base of the wall. The base of the board forms a 35° angle with the ground.
What is the length of the wooden board?
Round your answer to nearest tenth.
Answer:
The length of the wooden board is about 12.2 feet.
Step-by-step explanation:
Please refer to the diagram attached below.
The base of the board forms a 35° degree angle with the ground.
And we want to find the length of the wooden board.
Since we are given an angle and its adjacent length and we want to find the hypotenuse, we can use the cosine ratio:
[tex]\displaystyle \cos(\theta^\circ)=\frac{\text{adjacent}}{\text{hypotenuse}}[/tex]
The adjacent side is the distance from the wall to the board, which is 10 feet.
And the angle made is 35°.
The hypotenuse is the length of the wooden board. Therefore:
[tex]\displaystyle \cos(35)=\frac{10}{\ell}[/tex]
Solve for the length. Cross-multiply:
[tex]\displaystyle 10=\ell \cos(35)[/tex]
Therefore:
[tex]\displaystyle \ell=\frac{10}{\cos(35)}\approx12.2[/tex]
The length of the wooden board is about 12.2 feet.
Jessica had 8 sheets of paper. Water spilled on 2 sheets, so she threw them in the recycle bin. She drew 7 stars on each remaining sheet. How many stars did Jessica draw?
Answer:
42
Step-by-step explanation:
The remaining sheets of paper can be find in this way:
8-2 = 6
for each sheet of paper she drew 7 stars, so the total can be find in this way:
6 x 7 = 42 stars
Cameron created a composite figure by stacking three cubes the cubes measure 2 inches on each side  what is the volume of the composite figure
Answer:
24 cubic inches.
Step-by-step explanation:
The volume of one cube = s * s * s or s^3
s = 2 inches
V = s^3
V = 2 * 2 * 2 or 2^3
V = 8 cubic inches.
The volume of 3 of them is 8*3 = 24 cubic inches.

What is the scale factor from AABC to ADEF?
Answer:
C. 1/12
Step-by-step explanation:
The scale can be calculated by comparing side lenghts
AC is similar to FD and AB is similar to FE and BC is similar to ED
AB = 2 and FE = 24 so AB/FE is = 2/24 that's simplified is 1/12

Step-by-step explanation:
In a local 8-ball league, players are issued a handicap based on their ability. The handicap is used to adjust scores between players of different ability levels. The better a player is, the lower his or her handicap will be. What type of correlation exists between the skill of a player and his or her handicap?
Answer:
Negative correlation
Step-by-step explanation:
Correlation analysis is used to measure the type and degree of relationship which exists between two or more independent variables. Relationship between variables may be classed as Negative or positive depending on the nature or behavior of one variable relative to the other. Positive relationship exists when an increase on one variable leads to a corresponding increase in the other other variable.
However, in the scenario described above, handicap decreases with player quality that is the better a player is, the lower the handicap ; similarly, a player with higher handicap with have low quality, this is Hence a classic scenario of Negative correlation or relationship.
The equation of a circle is x2 + y2 - 12y + 20 = 0
What are the coordinates of the center and the length of the radius of the circle?
Answer:
Center: (0, 6); radius = 4
Step-by-step explanation:
x^2 + y^2 - 12y + 20 = 0
We must complete the square in y.
x^2 + y^2 - 12y = -20
x^2 + y^2 - 12y + 36 = -20 + 36
x^2 + (y - 6)^2 = 16
(x - 0)^2 + (y - 6)^2 = 4^2
Center: (0, 6); radius = 4

if a translation has a coordinate notation of (x,y) --> (x+1,y-3) then what is the image of (4,-4)
Answer:
(5, - 7 )
Step-by-step explanation:
A translation rule of
(x, y ) → (x + 1, y - 3 )
means add 1 to the original x- coordinate and subtract 3 from the original y- coordinate, that is
(4, - 4 ) → (4 + 1, - 4 - 3 ) → (5, - 7 )

draw the line of reflection that reflect quadrilateral ABCD onto quadrilateral A'B'C'D
Answer:
-3 across the x
Step-by-step explanation:
negative 3 is in the middle of the two, both between point -1 and -5, and point 0 and -6.
When a shape is reflected, it must be reflected over a line. The line of reflection of quadrilateral ABCD onto quadrilateral A'B'C'D is [tex]y = -3[/tex]
From the given graph, we have the following observations
ABCD was flipped over to form A'B'C'D'The line of reflection is between both shapesUsing points C and C' as reference;
We have:
[tex]C = (-3,-1)[/tex]
[tex]C' = (-3,-5)[/tex]
Notice that both points have the same x-coordinate
This means that the line of reflection is parallel to the x-axis, and it passes through the y-axis.
The point at which it passes through the y-axis is calculated using mid-point formula.
So, we have:
[tex]y = \frac{y_1 + y_2}{2}[/tex]
[tex]y = \frac{-1-5}{2}[/tex]
[tex]y = \frac{-6}{2}[/tex]
[tex]y = -3[/tex]
Hence, the line of reflection is [tex]y = -3[/tex]
See attachment for the line of reflection

Ben is making waffles for his 3 friends. The recipe calls for cup of bleached 2/3 flour and 1/4 cup of wheat flour. What is the total amount of flour Ben needs to make the waffles?
Answer:
2 3/4 cups of flour
Step-by-step explanation:
If Ben makes waffles for three friend then the recipe needs to be multiplied by three. First I would find the common denominator of 2 / 3 and 1/ 4. Then, I would add them together to get the answer of 11/12. After that, multiply the amount of times you are making the recipe (3). Then simplify
6 x 2/3 ??? yeah ik its not helping
Answer:
6 * 2/3 = 12/3 = 4
Step-by-step explanation.
you can think about it like this: 6 * 1/3 * 2
1/3 of 6 is 2 because 2 * 3 is 6
2 * 2 is 4, therefore the correct answer is 4
remember doing 6 * 2/3 is the same as doing 6/1 * 2/3 if that helps
