To find out how many packs of construction paper Ms. Perkins will need, divide the total number of pieces needed by the number of pieces in each pack. Using long division, we find that she will need at least 16 packs of construction paper.
Explanation:To find out how many packs of construction paper Ms. Perkins will need, we can divide the total number of pieces she needs (8,000) by the number of pieces in each pack (495). This will give us the number of packs required.
Using long division, we divide 8,000 by 495:
First, we divide 8,000 by 495 to get 16 with a remainder of 40.We then bring down the next digit, 0, making the new dividend 400.We divide 400 by 495, getting 0 with a remainder of 400.Finally, we bring down the 0, making the new dividend 4000. We divide 4000 by 495, getting 8 with a remainder of 40.Since the remainder is less than 495, we stop here. Therefore, Ms. Perkins will need at least 16 packs of construction paper.

Law of Sines and the Ambiguous Case.
m < A = 34*
a = 9
c = 6
How many distinct triangles can be drawn given these measurements?
Answer:
One
Step-by-step explanation:
9/sin(34) = 6/sinC
sinC = 0.372795269
C = 21.9, 158.1
Since 158.1 + 34 = 192.1 > 180
Only one triangle can be formed with angle 21.9° at C
Sin(146° + ∠B) cannot exceed 1, there is no solution for b that satisfies the triangle inequality. Therefore, no distinct triangle can be drawn with the given measurements.
To determine the number of distinct triangles that can be drawn with the given measurements using the Law of Sines, we need to consider the Ambiguous Case (also known as the SSA case or the "side-side-angle" case).
The Law of Sines states:
sin(A) / a = sin(B) / b = sin(C) / c
Given:
m∠A = 34°
a = 9
c = 6
We want to find ∠B and side b.
First, find ∠B using the Law of Sines:
sin(B) / b = sin(A) / a
sin(B) / b = sin(34°) / 9
Now, find sin(34°):
sin(34°) ≈ 0.5592
Now, solve for sin(B) by multiplying both sides by b:
sin(B) = (0.5592 * b)
Next, find ∠C:
Since the sum of angles in a triangle is 180°:
∠C = 180° - ∠A - ∠B
∠C = 180° - 34° - ∠B
Determine the value of side b:
Using the Law of Sines again, we have:
sin(C) / b = sin(A) / a
sin(C) / b = sin(34°) / 9
Find sin(C):
sin(C) = sin(180° - 34° - ∠B)
We can now use the fact that sin(C) = sin(180° - angle) to find sin(C):
sin(C) = sin(180° - 34° - ∠B) = sin(146° + ∠B)
Now, solve for b by multiplying both sides by b:
sin(146° + ∠B) = (sin(34°) / 9) * b
Since sin(146° + ∠B) cannot be greater than 1 (the maximum value for sine), the number of distinct triangles will depend on the possible values of b.
In this case, we have sin(146° + ∠B) = (sin(34°) / 9) * b, and since sin(34°) ≈ 0.5592, the maximum value for (sin(34°) / 9) * b is approximately 0.5592 * 6 ≈ 3.3552.
Since sin(146° + ∠B) cannot exceed 1, there is no solution for b that satisfies the triangle inequality. Therefore, no distinct triangle can be drawn with the given measurements.

Step-by-step explanation:
According to the flaring, the triangle expressed in the figure is formed.
Now we have a vector A and vector B, whose components are Ax, Ay and Bx and By respectively.
To calculate these components you must use the following formulas:
Ax = A * cos [angle a] = 32 * cos 37 ° = 25.6
Ay = A * sin [angle a] = 32 * sin 37 ° = 19.3
Bx = B * cos [angle a] = 21 * cos 23 ° = 19.3
By = B * sin [angle b] = 21 * sin 23 ° = - 8.2
In the figure it can be seen that vector B is the result of vector A and vector C
Thus:
B = A + C
reorganizing is:
C = B - A
Now to calculate Cx and Cy, we will do it with the previously calculated components:
Cx = Bx - Ax = 19.3 - 25.6 = -6.3
Cy = By - Ay = -8.2 - 19.3 = -27.5
Now to calculate the value of vector C, we apply the following formula:
C ^ 2 = Cx ^ 2 + Cy ^ 2
Rearranging:
C = (Cx ^ 2 + Cy ^ 2) ^ (1/2)
C = [(-6.3 ^ 2) + (27.5 ^ 2)] ^ (1/2) = 28.2
Then the distance would be 28.2 meters.

Mary Ward recently leased a new convertible. The $1600 due at signing inc the title and license fee. Her monthly lease payments are $700 per mont leasing company allows 12,000 miles per year with a $0.12 per mile overage charge. If the total lease cost is $26,800, for how many months does the lease ludes . The last?
This calculation shows that Mary Ward's lease term is 36 months.
The question is asking us to find out for how many months Mary Ward's car lease lasts. To do so, we need to calculate the total monthly payments and then subtract the initial $1600 fee to find the total cost of the monthly payments alone. Then, we divide this amount by the monthly lease payment to determine the total number of months for the lease duration.
First, we deduct the initial fee from the total lease cost:
Total lease cost - Initial fee = Total of monthly payments
$26,800 - $1,600 = $25,200
Next, we divide this result by the monthly lease payment to find out the number of months:
$25,200 / $700 = 36 months
Therefore, the lease agreement lasts for 36 months, which is typically the term for most vehicle leases.

Answer: the solutions of the equation are
x = - 1
x = 8
x = 9
Step-by-step explanation:
The given cubic equation is expressed as
x³ - 16x² + 55x + 72 = 0
The first step is to test for any value of x that satisfies the equation when
x³ - 16x² + 55x + 72 = 0
Assuming x = - 1, then
- 1³ - 16(-1)³ + 55(-1) + 72 = 0
- 1 - 16 - 55 + 72 = 0
0 = 0
It means that x + 1 is a factor.
To determine the other factors, we would apply the long division method. The steps are shown in the attached photo. Looking at the photo, we would factorize the quadratic equation which is expressed as
x² - 17x + 72 = 0
x² - 9x - 8x + 72 = 0
x(x - 9) - 8(x - 9) = 0
(x - 9)(x - 8) = 0

What is the probability of getting a license plate that has a repeated letter or digit if you live in a state in which license plates have two letters followed by four numerals? (Round your answer to one decimal place.)
In a state where the license plates have two letters followed by four numerals, the probability of getting a license plate that has a repeated letter or digit is approximately 51.5%.
Explanation:To solve this question, we need to understand the fundamental counting principle and the concept of probability. First, let's explore the total number of possibilities for a license plate of this format. The choice for each spot on the license plate is independent of each other. Therefore, there are 26 possibilities (26 letters in the English alphabet) for each of the first two spots, and 10 possibilities for each of the next four spots (0-9 digits). The total number of possibilities is thus 26 * 26 * 10 * 10 * 10 * 10, or 67,600,000 combinations.
Next, we will calculate all the combinations in which no letters or digits are repeated. There are 26 options for the first letter, 25 remaining options for the second letter, 10 options for the first digit, and then 9, 8, and 7 options for the next three positions, giving us 26 * 25 * 10 * 9 * 8 * 7 = 327,600,000 combinations.
To get the probability of a repeated letter or digit, subtract the non-repeating combinations from the total combinations, divide by the total, and then multiply by 100 to get a percentage. So the probability is (676,000,000 - 327,600,000) / 676,000,000 * 100, which gives approximately 51.5%

The average wall thickness of 25 panes of glass is 4.05 mm. The standard deviation of the thickness of the 25 panes is measured to be 0.08 mm. What is the 90% confidence interval of the mean of wall thickness
Answer:
u => 4,028
Step-by-step explanation:
To find the answer, we have the following formula:
u => m - t (alpha, n-1) * [sd / (n) ^ (1/2)]
where m is the mean.
where sd is the standard deviation.
where n is the sample size.
t is a parameter that depends on the confidence interval and the sample size.
alpha = 1 - ci
ci = 90% = 0.9
Therefore, alpha = 1 - 0.9 = 0.1.
n - 1 = 25 - 1 = 24
So it would come being t (0.1, 24), if we look in the table, which I will attach the value of t is equal to 1.318.
We know the rest of the values, m = 4.05; sd = 0.08; n = 25
u => 4.05 - 1,318 * [0.08 / (25) ^ (1/2)]
u => 4.028
Which means that the interval with a 90% confidence of the wall thickness measurement is:
u => 4.028

Answer:
The answer to your question is Positive
Step-by-step explanation:
Function
g(x) = x⁴ - 8x³ + x² + 42x
To know if the function is positive or negative in the interval (0, 3), look for two numbers between this interval and evaluate the function.
The numbers I chose were 1 and 2
- g(1) = (1)⁴ - 8(1)³ + (1)² + 42(1)
= 1 - 8 - 1 + 42
= + 36 positive
- g(2) = (2)⁴ - 8(2)³ + (2)² + 42(2)
= 16 - 64 + 4 + 84
= + 40

The function is positive in the interval (0, 3)
Suppose that a brand of lightbulb lasts on average 1730 hours with a standard deviation of 257 hours. Assume the life of the lightbulb is normally distributed. Calculate the probability that a particular bulb will last from 1689 to 2267 hours?
Answer:
P [ 1689 ≤ X ≤ 2267 ] = 54,88 %
Step-by-step explanation:
Normal Distribution
Mean μ₀ = 1730
Standard Deviation σ = 257
We need to calculate z scores for the values 1689 and 2267
We apply formula for z scores
z = ( X - μ₀ ) /σ
X = 1689 then
z = (1689 - 1730)/ 257 ⇒ z = - 41 / 257
z = - 0.1595
And from z table we get for z = - 0,1595
We have to interpolate
- 0,15 0,4364
- 0,16 0,4325
Δ = 0.01 0.0039
0,1595 - 0,15 = 0.0095
By rule of three
0,01 0,0039
0,0095 x ?? x = 0.0037
And 0,4364 - 0.0037 = 0,4327
Then P [ X ≤ 1689 ] = 0.4327 or P [ X ≤ 1689 ] = 43,27 %
And for the upper limit 2267 z score will be
z = ( X - 1730 ) / 257 ⇒ z = 537 / 257
z = 2.0894
Now from z table we find for score 2.0894
We interpolate and assume 0.9815
P [ X ≤ 2267 ] = 0,9815
Ths vale already contains th value of P [ X ≤ 1689 ] = 0.4327
Then we subtract to get 0,9815 - 0,4327 = 0,5488
Finally
P [ 1689 ≤ X ≤ 2267 ] = 0,5488 or P [ 1689 ≤ X ≤ 2267 ] = 54,88 %

A Chinese restaurant uses about 15 exponent 2 appearance of chopsticks each day the manager wants to order a 30-day supply of chopsticks chopsticks come in boxes of 750. How many boxes should the manager order
Answer:
9 boxes of chopsticks.
Step-by-step explanation:
The first thing is to calculate the number of chopsticks spent in a day, the problem tells us that they are 15 ^ 2 = 15 * 15 = 225 chopsticks daily.
To calculate the number of chopsticks in 30 days, it is to calculate the previous amount by 30:
225 * 30 = 6750 chopsticks spent in one month.
To know how many boxes you should order is to divide the total number of chopsticks in a month and the number of chopsticks that a box brings that are 750:
6750/750 = 9 boxes of chopsticks.
Therefore you should order exactly 9 boxes of chopsticks for the restaurant's need.
You return a DVD movie that was 5 days overdue including a previous unpaid balance of $2.50, your new balance is $7.75. How much is the daily fine for an overdue DVD?
Answer:
$ 1.05
Step-by-step explanation:
To solve the problem it is necessary to pose some equations, which are the following:
Debt DVD = New Balance - Old Balance
With this we will calculate the net value that only has to do with the debt of the DVD:
Debt DVD: 7.75 - 2.50 = 5.25
Now, the other equation is the value per day that generates a delay.
Debt DVD / # days
Replacing
5.25 / 5 = 1.05
Then the daily fine for a overdueDVD is $ 1.05
An ABA standard basketball can have a diameter of up to 25cm how much space is there for air inside a standard basketball
Answer:
[tex]8181.23 \ cm^3[/tex]
Step-by-step explanation:
-A standard basketball has a spherical shape.
-Given the ball has a diameter of 25cm.
-The space available for air is equivalent to the ball's volume and is calculated as:
[tex]V=\frac{4}{3}\pi r^3, D=25\\\\=\frac{4}{3}\pi (D/2)^3\\\\\frac{4}{3}\pi (25/2)^3\\\\=8181.23\ cm^3[/tex]
Hence, the space available for air is [tex]8181.23 \ cm^3[/tex]

One of the THEOREM for triangles states that, A LINE DRAWN PARALLEL TO ONE SIDE OF THE TRIANGLE DIVIDES THE OTHER TWO SIDES IN THESAME RATIO.
From the figure above:
VW is parallel to SU.
VW divides ST and TU in thesame ration.
Hence:
TV / SV = TW / UW
14 / 6 = 21 / (x - 4)
Cross Multiplying gives:
14( x - 4) = 6 * 21
14x - 56 = 126
14x = 126 + 56
14x = 182
Divide through by 14.
x = 182/14
x = 13
If Henry were to add 5 gallons of water to a tank that is already 3434 full of water, the tank would be 7878 full. How many gallons of water would the tank hold if it were full
Answer:
The tank would hold 40 gallons of water when full.
Step-by-step explanation:
The tank is already 3/4 full of water
If Henry added 5 gallons, it will be 7/8 full.
Therefore the fraction added by Henry =7/8-3/4=1/8
It means that 1/8 of the total=5 gallons of water
Let the total capacity of the tank=x
[tex]\frac{1}{8}Xx=5 gallons\\ x=8X5=40 gallons[/tex]
The tank would hold 40 gallons of water when full.
Will give Brainliest to CORRECT answer! Please Help! A cylinder has a diameter of 5 m and a height of 10 m. What is its volume? Choose all that apply.?
A. π(2.5)^2 (10) m^3
B. π(5)^2 (10) m^3
C. 62.5π m^3
D. 250π m^3
Answer:
A, C
Step-by-step explanation:
You want the volume of a cylinder with diameter 5 m and height 10 m.
VolumeThe volume is given by the formula ...
V = πr²h . . . . . . . where r = radius = half the diameter
The diameter is 5 m, so the radius is 5/2 = 2.5 m. Using the given values in the formula, we find the volume of the cylinder to be ...
V = π(2.5)²(10) m³ . . . . . . matches choice A
= 62.5π m³ . . . . . . . . . . . matches choice C
