Shape 2: 7 matchsticks (Shape 1 + 3 matchsticks)
Shape 3: 10 matchsticks (Shape 2 + 3 matchsticks)
Shape 4: 13 matchsticks (Shape 3 + 3 matchsticks)
Based on this pattern, it appears that each shape adds three additional matchsticks compared to the previous shape.
Now, let's analyze the last two shapes:
Shape 6: 43 matchsticks
Shape 7: 82 matchsticks
From Shape 4 to Shape 6, there is an increase of 3 matchsticks as expected.
However, from Shape 6 to Shape 7, there is an unexpected increase of 39 matchsticks.
Since the given information does not provide a clear pattern or rule for the last two shapes, we cannot accurately determine the number of matchsticks for those shapes.
Therefore, we can complete the table as follows:

The segment lengths are given as follows:
6. AB = 15.
7. RS = 47.
How to obtain the length of segment TU?The length of segment TU is obtained applying the trapezoid midsegment theorem, which states that the length of the midsegment of the trapezoid is equals to the mean of the length of the bases of the trapezoid.
For item 6, we have that the mean of AB = x and 29 is of 22, hence:
(x + 29)/2 = 22
x + 29 = 44
x = AB = 15.
The value of x in item 7 is obtained as follows:
3x + 5 = (2x + 15 + 6x - 37)/2
8x - 22 = 6x + 10
2x = 32
x = 16.
Hence the length of RS is given as follows:
RS = 2 x 16 + 15
RS = 47.

Determine the length of the leg of 45* -45*-90* triangle with a hypotenuse length of 26
The length of leg of given triangle is s 13√(2) units.
A 45-45-90 triangle is a special right triangle in which the two legs are congruent and the angles opposite the legs are both 45 degrees. The hypotenuse is the longest side of the triangle and is located opposite the right angle.
In this problem, we are given that the hypotenuse length of a 45-45-90 triangle is 26 units. Our goal is to find the length of one of the legs of the triangle. Let us denote the length of one of the legs as x.
By the Pythagorean theorem, we know that the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse. In a 45-45-90 triangle, the two legs are congruent, so we can set up the following equation:
x² + x² = 26²
Simplifying the left-hand side of the equation, we get:
2x² = 676
Dividing both sides by 2, we get:
x² = 338
Taking the square root of both sides, we get:
x = √(338)
Since we are asked to give the answer in simplified radical form, we can write:
x = √(2 × 169) = √(2) × √(169) = 13√(2)
Therefore, the length of one of the legs of the 45-45-90 triangle with a hypotenuse length of 26 units is 13√(2) units.

Jesus works at a computer outlet. He receives a bi-weekly salary of
$300 plus 5. 5% commission on his sales. In the last two weeks, he sold
$16,200 of computer equipment. He pays 8% for State Income Tax,
12. 3% for Federal Income Tax, 6. 3% for Social Security, and 1. 45%
for Medicare. What steps did I take to find Jesus' net bi-weekly
pay? (Show your work)
Jesus' net bi-weekly pay is $856.69 after paying his taxes and deductions.
To find Jesus' net bi-weekly pay, I followed these steps:
Calculate Jesus' commission: Jesus sold $16,200 of computer equipment, so his commission is 5.5% of $16,200, which is $891.
Calculate Jesus' gross bi-weekly pay: Jesus receives a bi-weekly salary of $300 plus his commission of $891, so his gross bi-weekly pay is $1,191.
Calculate Jesus' deductions: Jesus pays 8% for State Income Tax, 12.3% for Federal Income Tax, 6.3% for Social Security, and 1.45% for Medicare. To calculate the deductions, I multiplied his gross bi-weekly pay by each percentage rate:
State Income Tax: 8% of $1,191 = $95.28
Federal Income Tax: 12.3% of $1,191 = $146.67
Social Security: 6.3% of $1,191 = $75.09
Medicare: 1.45% of $1,191 = $17.27
Subtract the deductions from the gross bi-weekly pay: To find Jesus' net bi-weekly pay, I subtracted the total deductions of $334.31 from his gross bi-weekly pay of $1,191:
Net bi-weekly pay = $1,191 - $334.31 = $856.69
Therefore, Jesus' net bi-weekly pay is $856.69 after paying his taxes and deductions.

The local regional transit authority of a large city was interested in determining the mean commuting time for workers who drove to work. They selected a random sample of 125 residents of the metropolitan region and asked them how long they spent commuting to work (in minutes). A 95% confidence interval was constructed and reported as (27. 74, 30. 06). Interpret the interval in the context of this problem. 2. A long distance telephone company recently conducted research into the length of calls (in minutes) made by customers. In a random sample of 45 calls, the sample mean was minutes and the standard deviation was s 5. 2 minutes. (a) Find a 95% confidence interval for the true mean length of long distance telephone calls made by customers of this company. X 1. 68
For the first problem, we can interpret the confidence interval as follows:
We are 95% confident that the true mean commuting time for workers who drive to work is between 27.74 and 30.06 minutes.
This means that if we were to repeat the sampling process many times and construct a 95% confidence interval each time, about 95% of those intervals would contain the true mean commuting time.
For the second problem, we can use the following formula to find a 95% confidence interval for the true mean length of long distance telephone calls:
[tex]CI = X ± t*(s/sqrt(n))[/tex]
Where X is the sample mean, s is the sample standard deviation, n is the sample size, and t is the t-value from the t-distribution with n-1 degrees of freedom for a 95% confidence interval.
Plugging in the values given, we get:
[tex]CI = 1.68 ± t*(5.2/sqrt(45))[/tex]
To find the value of t, we can look it up in a t-distribution table or use a calculator. For a 95% confidence interval with 44 degrees of freedom, we get t = 2.015.
Plugging this value in, we get:
[tex]CI = 1.68 ± 2.015*(5.2/sqrt(45)) = (0.86, 2.50)[/tex]
So we can interpret the interval as follows:
We are 95% confident that the true mean length of long distance telephone calls made by customers of this company is between 0.86 and 2.50 minutes longer or shorter than the sample mean of 1.68 minutes.

You buy a sheet with 10 stamps. Some are 45 cents and some are 30 cents. If it cost $4. 20 how many of each did you get
You bought 8 stamps that cost 45 cents each and 2 stamps that cost 30 cents each.
Let's assume you bought x stamps that cost 45 cents each and y stamps that cost 30 cents each.
From the given information, we can create two equations:
The total number of stamps is 10: x + y = 10.
The total cost is $4.20: 45x + 30y = 420 (since the cost is given in cents).
Now we can solve this system of equations to find the values of x and y.
We can multiply the first equation by 30 to eliminate y:
30x + 30y = 300.
Now we have a system of equations:
30x + 30y = 300,
45x + 30y = 420.
Subtracting the first equation from the second equation, we get:
45x + 30y - (30x + 30y) = 420 - 300,
15x = 120,
x = 120/15,
x = 8.
Substituting the value of x back into the first equation:
8 + y = 10,
y = 10 - 8,
y = 2.

Jane moved from a house with 78 square feet of closet space to an apartment with 47.58 square feet of closet space. what is the percentage decrease of jane's closet space?
Jane's closet space decreased by approximately 38.97%.
To find the percentage decrease of Jane's closet space, we need to first calculate the amount of decrease and then express it as a percentage of the original value.
The amount of decrease is the difference between the original closet space and the new closet space:
Decrease = Original closet space - New closet space
Decrease = 78 - 47.58
Decrease = 30.42
So Jane's closet space decreased by 30.42 square feet.
To express this decrease as a percentage of the original value, we use the following formula:
Percentage decrease = (Decrease / Original value) x 100%
Substituting the values, we get:
Percentage decrease = (30.42 / 78) x 100%

Point A
where y=x-2.
This projects that for every x value, y will be 2 less than that x value. So if we place in x=0, we get y=-2. If we plug in x=1, we get y=-1 and so on. So we could plot these points on the coordinate plane as (0,-2), (1,-1), (2,0), (3,1) .
Then, similarly point B
where y=-x-2.
This projects that for every x value, y should be 2 less than the negative of that x value. So if we place in x=0, we get y=-2. If we place in x=1, we get y=-3 and .
Then, we can place these points on the coordinate plane as (0,-2), (1,-3), (-1,-1), (2,-4) .
Finally let's proceed on to point C where y=|x|-2. This projects that for every positive x value, y will be 2 less than that x value and for every negative x value, y will be 2 less than the negative of that x value. So if we plug in x=0, we get y=-2. If we plug in x=1, we get y=-1 and so on.

solve the triangle.
angle C = 16°
angle c = 32
angle b = 92
Find angle B, a, and A
Answer:
Step-by-step explanation:
To solve the triangle, we can use the law of sines and the fact that the sum of the angles in a triangle is 180 degrees.
First, we can find angle A by using the fact that the sum of the angles in a triangle is 180 degrees:
A = 180 - B - C
A = 180 - 92 - 16
A = 72 degrees
Next, we can use the law of sines to find side a:
a/sin(A) = c/sin(C)
a/sin(72) = 32/sin(16)
a = (32*sin(72))/sin(16)
a ≈ 89.4
Finally, we can use the fact that the sum of the angles in a triangle is 180 degrees to find angle B:
B = 180 - A - C
B = 180 - 72 - 16
B = 92 degrees
Therefore, the triangle has angle B = 92 degrees, angle A = 72 degrees, and side a ≈ 89.4.

Victoria drove 76 miles, burning 4 gallons of gasoline. She knows the total number of miles she can drive is proportional to the number of gallons of gas she burns and wants to create an equation that can be used to predict the number of miles she can drive for any number of gallons of gas used. Drag the correct values to create an equation which will accurately represent the total number of miles, m, Victoria should expect to be able to drive if she uses g gallons of gasoline
The equation that represents the total number of miles, m, Victoria should expect to be able to drive if she uses g gallons of gasoline is m = (19g).
We can determine the proportionality constant by dividing the total number of miles driven (76) by the number of gallons of gasoline burned (4), which gives us 19 miles per gallon (76/4 = 19).
We can then use this proportionality constant to create the equation m = (19g), where m represents the total number of miles Victoria should expect to be able to drive if she uses g gallons of gasoline. This equation tells us that for every additional gallon of gasoline burned, Victoria should expect to be able to drive an additional 19 miles.
For example, if Victoria were to burn 6 gallons of gasoline, she should expect to be able to drive 114 miles (6 x 19 = 114). This equation assumes that Victoria's car has a constant fuel efficiency of 19 miles per gallon.

Use substitution to find the indefinite integral. szve ? 2 zV9z+ - 5 dz [21922-5 Zy9z 9z- 5 dz = =]
To solve this problem, we can use substitution. Let u = 9z - 5, then du/dz = 9 and dz = du/9.
Using this substitution, we can rewrite the integral as:
∫(2/(u+5))(1/9)du
Simplifying this expression:
(2/9) ∫(1/(u+5))du
We can then solve this integral by using the formula for the natural logarithm:
(2/9) ln|u+5| + C
Substituting back in for u:
(2/9) ln|9z| + C
2 zV9z+ - 5 dz is (2/9) ln|9z| + C.
Consider the integral:
∫2z√(9z² - 5) dz
We can use the substitution method. Let's choose the substitution:
u = 9z² - 5
Now, differentiate u with respect to z:
du/dz = 18z
Solve for dz:
dz = du/(18z)
Now, substitute u and dz back into the integral and simplify:
∫(2z√u) * (du/(18z)) = (1/9)∫√u du
Now, integrate with respect to u:
(1/9)(2/3)(u^(3/2))/(3/2) + C = (2/27)u^(3/2) + C
Finally, substitute back the original expression for u:
(2/27)(9z² - 5)^(3/2) + C

To find the rate at which the area is changing, we need to find dA/dt, the derivative of the area with respect to time. We can use the chain rule to find this derivative:
dA/dt = dA/dr * dr/dt
We can find dA/dr by taking the derivative of the area formula with respect to r:
dA/dr = 2πr
Now we can substitute the values we know into the chain rule formula:
dA/dt = dA/dr * dr/dt = 2πr * 5
When the radius is 28 mm, the rate of change of the area is:
dA/dt = 2π(28) * 5 = 280π ≈ 879.64 mm^2/s
Therefore, the area is changing at a rate of approximately 879.64 mm^2/s when the radius is 28 mm.

Anita plans to take $2600 loan for one year at an annual interest rate of 14% compounded monthly. She plans to pay off the loan in one payment at the end of the year. Multiplying 2600 by 0. 14, she determines she will pay $364 in interest on the loan. Describe the error and calculate how much interest she will pay
The actual interest paid by Anita is $2949.44 - $2600 = $349.44 (rounded to the nearest cent).
In this case, we have:
P = $2600
r = 0.14 (14%)
n = 12 (compounded monthly)
t = 1 (one year)
Plugging in the values, we get:
A = $2600(1 + 0.14/12)^(12*1)
= $2600(1.0116667)^12
= $2949.44
Interest refers to the amount of money charged by a lender to a borrower for the use of borrowed funds. It is typically expressed as a percentage of the amount borrowed and is usually charged over a specified period of time, such as a month or a year.
Interest can be either simple or compound. Simple interest is calculated only on the principal amount borrowed, while compound interest is calculated on the principal amount as well as any accumulated interest. This means that with compound interest, the borrower ends up paying more in interest over time. Interest rates can vary depending on a range of factors, such as the borrower's credit score, the length of the loan, and prevailing market conditions. In general, higher-risk borrowers are charged higher interest rates, while lower-risk borrowers are charged lower rates.

You get a part time job earning $12.50/hr. Tips are $4.60/hr average. Deductions are FICA (7.65%) and Federal Tax Withholding (10%). You work for 18 hours. What is your gross base pay?
If you are earning $12.50/hr in a part-time job, then your gross "base-pay" after deductions is $253.48.
Your base pay is $12.50/hr and you worked for 18 hours, so the base pay would be:
⇒ $12.50/hr × 18 hrs = $225;
The tips are $4.60/hr on average, so the "total-tips" earned would be:
⇒ $4.60/hr × 18 hrs = $82.80;
To calculate the "total-deductions", we first find the total percentage deducted, which is the sum of FICA and Federal Tax Withholding:
⇒ 7.65% + 10% = 17.65%,
To find the total amount deducted, we multiply the total percentage deducted by the "base-pay" + "tips";
⇒ 17.65% x ($225 + $82.80) = $54.32,
So the pay, before any deductions, is the sum of "base-pay" and "tips";
⇒ $225 + $82.80 = $307.80;
To find the "net-pay", we subtract "total-deductions" from pay;
We have,
⇒ $307.80 - $54.82 = $253.48,
Therefore, your gross base pay is $253.48.

Step-by-step explanation:
In between classes, Jade plays a game of online Monopoly on her laptop. Using the sample space for rolling two dice that you created in the Group portion of this lesson, find the probability that when Jade rolls the two dice, she gets the outcome given. Express your answers in exact simplest form
The probability that Jade gets the specific outcome you're interested in when rolling two dice is 1/6.
To find the probability that Jade gets a specific outcome when rolling two dice, we will use the sample space for rolling two dice, which consists of 36 possible outcomes (since there are 6 sides on each die, and we have 2 dice: 6 x 6 = 36).
Step 1: Determine the specific outcome you are interested in (for example, the sum of the numbers on the dice being 7).
Step 2: Count the number of ways this outcome can occur. For example, if we want a sum of 7, there are 6 possible outcomes: (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), and (6, 1).
Step 3: Calculate the probability by dividing the number of successful outcomes by the total number of possible outcomes in the sample space.
In our example, there are 6 successful outcomes, and there are 36 possible outcomes in the sample space:
Probability = (Number of successful outcomes) / (Total number of possible outcomes) = 6/36
Step 4: Express the probability in its simplest form by reducing the fraction. In our example, 6/36 can be reduced to 1/6.
So, the probability that Jade gets the specific outcome you're interested in when rolling two dice is 1/6.
