Mr. Moore needs 13.5 cubic feet of soil to fill the planter box.
To calculate the volume of the rectangular prism planter box, we need to multiply the length, width, and height of the box.
Volume = length x width x height
V = 4.5 ft x 2 ft x 1.5 ft
V = 13.5 cubic feet
Therefore, Mr. Moore needs 13.5 cubic feet of soil to fill the planter box.
It is important to note that the volume of the box represents the amount of space inside the box and does not take into account any obstructions or irregularities that may be present inside the box.
Thus, the actual amount of soil required may be slightly different from the calculated value. Additionally, it is always a good idea to add some extra soil to account for settling and to ensure that the planter box is completely filled.

Two angles lie along a straight line. If m∠A is four times the sum of m∠B plus 17.5°, how many degrees is m∠B?
A straight angle split into two adjacent angles, Ay and B.
The measure of angle B on the straight line is 22 degrees
How to determine the measure of angle BWhen two angles lie along a straight line, they form a straight angle which measures 180 degrees.
The statement from the question can be represented as
m∠A = 4(m∠B + 17.5°)
But we know that the sum of the measures of angles A and B is 180 degrees, since they form a straight angle.
m∠A + m∠B = 180°
Substitute the known values in the above equation, so, we have the following representation
4(m∠B + 17.5°) + m∠B = 180°
Simplifying this equation, we get:
5m∠B + 70° = 180°
Subtracting 70 degrees from both sides, we get:
5m∠B = 110°
Dividing both sides by 5, we get:
m∠B = 22°
Therefore, the measure of angle B is 22 degrees.

Answer:

Step-by-step explanation:
Given that W is directly proportional to the square of V, and W=50 when V=5 , find W when V=9 .
Answer:
k=2 when W=50,V=5
W=162 when V=9,k=remains constant
Step-by-step explanation:
W=V²
W=kV²
50=k×5²
50=k×25
50=25k
divide both sides by 25
k=2
k remains constant
W=KV²
W=2×9²
W=2×81
W=162
How can you isolate the term ? f/2+9= 4 ? ? on both sides.
The first ? has add,sub,multiple by,and divide by.
The second ? has -9, -4, 4,and 9.
For the isolated term the value of f/2 is -2.5
Given the equation f/2+9=4, we need to isolate the term f/2 to solve for the value of f. To do so, we need to perform the same operation on both sides of the equation in order to keep it balanced.
One way to isolate f/2 is to subtract 9 from both sides of the equation. This would give us:
f/2 = -5
By subtracting 9 from both sides, we removed the constant term from the left side of the equation. This operation did not affect the capacity of the equation, as we simply moved a constant value from one side to the other.
Another way to isolate f/2 is to multiply both sides of the equation by 2. This would give us:
f + 18 = 8
By multiplying both sides by 2, we eliminated the denominator on the left side of the equation, and the capacity of the equation remained unchanged.
Next, to isolate the term f, we need to perform the same operation on both sides of the equation, but this time with a different set of values.
To isolate f, we can subtract 18 from both sides of the equation. This would give us:
f = -10
By subtracting 18 from both sides, we removed the constant term from the right side of the equation, and the capacity of the equation remained the same.
We can also isolate f by dividing both sides of the equation by 2. This would give us:
f/2 = -2.5
By dividing both sides by 2, we eliminated the numerator on the left side of the equation, and the capacity of the equation remained unchanged.

The diameters of cherry tomatoes produced by a large farm have an approximately Normal distribution, with a
mean diameter of 22 mm and a standard deviation of 2.5 mm. After they are picked and washed, tomatoes with
diameter of at most 15 mm or at least 30 mm are rejected and not sold. What proportion of such tomatoes are
rejected?
Find the z-table here.
0.0033
0.0201
0.9799
0.9967
The proportion of cherry tomatoes that are rejected due to being at most 15 mm or at least 30 mm in diameter is approximately 0.0040, or 0.4%.
We need to first determine the z-scores corresponding to these values in order to determine the percentage of cherry tomatoes that are rejected because they are either at most 15 mm or at least 30 mm in diameter. Where x is the diameter, is the mean diameter, and is the standard deviation, we can apply the formula.
The z-score for a 15 mm diameter is z = (15 - 22) / 2.5 = -2.8. The z-score for a 30 mm diameter is z = (30 - 22) / 2.5 = 3.2.
As the tomatoes that go outside the range between these two z-scores are the ones that are rejected, we are interested in learning what percentage of tomatoes do so. The area under the normal curve outside of this range can be calculated using a calculator or a conventional normal distribution table.
Left of z = -2.8 is the area of 0.0033, while right of z = 3.2 is the area of 0.0007. We multiply these two probabilities together to get the total area outside of this range: 0.0033 + 0.0007 = 0.0040.
As a result, 0.4%, or around 0.0040, of cherry tomatoes are rejected because they have a diameter of at least 30 mm and no more than 15 mm.
The option that comes the closest to the correct response is 0.0033. That is not the appropriate answer since it only considers the region to the left of z = -2.8 and excludes the region to the right of z = 3.2.

-$3,824.20
-$3,648.60
-$3,546.70
Alexandra's net pay each month, using mathematical operations, is C. $3,648.60.
What is the net pay?The net pay is the difference between the gross pay or earning and the total deductions.
The net pay per month can be computed following these steps:
Gross earnings per year = $59,904.00
Monthly taxes = $998.40
Annual taxes = $11,980.80 ($998.40 x 12)
Monthly medical, dental, and vision insurance = $345.00
Annual medical, dental, and vision insurance = $4,140 ($345 x 12)
Total deductions and taxes = $16,120.80 ($11,980.80 + $4,140)
Annual net pay = $43,783.20 ($59,904.00 - $16,120.80)

Chris works at a bookstore and earns $7. 50 per h hour plus a $2 bonus for each book she sells. Chris sold 15 books. She
wants to earn a minimum of $300. Which inequality represents this situation, and what quantities are true for h?
The inequality that represents this situation is (x × y) + (z x n) ≥ $300 and the quantities are true for h when the value is 36.
To find the value of h (the number of hours Chris needs to work), we can rearrange the inequality as follows:
Base wage x Number of hours worked ≥ $300 - Bonus per book x Number of books sold
Number of hours worked ≥ ($300 - Bonus per book x Number of books sold) / Base wage
Now, let's substitute the values we know into this equation. We know that Chris earns a base wage of $7.50 per hour and a $2 bonus for each book sold. We also know that she sold 15 books. Therefore:
Number of hours worked ≥ ($300 - $2 x 15) / $7.50
Number of hours worked ≥ ($300 - $30) / $7.50
Number of hours worked ≥ $270 / $7.50
Number of hours worked ≥ 36
So, the inequality that represents this situation is:
Base wage x Number of hours worked + Bonus per book x Number of books sold ≥ $300
Now, let us consider that x refers the Base wage, y refers the Number of hours worked, z refers the Bonus per book and n refers the Number of books sold, then the resulting inequality is
=> (x × y) + (z x n) ≥ $300
And the true value of h (the number of hours Chris needs to work) is at least 36 hours.

Select whether AB and CD are parallel, perpendicular, or neither.
A(8, 4), B(4, 3), C(4, -9), D(2, -1)
The slopes of AB and CD are neither equal nor negative reciprocals of each other, we can conclude that AB and CD are neither parallel nor perpendicular.
To determine if AB and CD are parallel, perpendicular, or neither, we need to find the slopes of both lines.
The slope of AB can be found using the formula:
m = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) = (8, 4) and (x₂, y₂) = (4, 3).
mAB = (3 - 4) / (4 - 8) = -1/4
The slope of CD can be found using the formula:
m = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) = (4, -9) and (x₂, y₂) = (2, -1).
mCD = (-1 - (-9)) / (2 - 4) = 8 / (-2) = -4
If the two lines are parallel, their slopes must be equal. However, mAB = -1/4 and mCD = -4, so the two lines are not parallel.
If the two lines are perpendicular, their slopes must be negative reciprocals of each other. That is, mAB x mCD = -1.
However, mAB x mCD = (-1/4) x (-4) = 1, which is not equal to -1. Therefore, the two lines are not perpendicular either.

The formula F = \frac{9}{5} C + 32$ can be used to convert temperatures between degrees Fahrenheit ($F$) and degrees Celsius ($C$). What Celsius temperature $C$ has the same value when converted to a Fahrenheit temperature $F$?
The Celsius temperature that has the same value as when converted to a Fahrenheit temperature is -40
What Celsius temperature has the same value as FFrom the question, we have the following parameters that can be used in our computation:
F = 9/5C + 32
The Celsius temperature that has the same value as F implies that
C = F
Substitute the known values in the above equation, so, we have the following representation
C = 9/5C + 32
So, we have
C - 9/5C = 32
Evaluate the like terms
-4/5C = 32
So, we have
C = -32 * 5/4
Evaluate
C = -40
Hence, the value of C is -40

Use pencil and paper. If the manager of the store wants approximately half of the customers to receive the 25% discount, does this seem like an appropriate method? Explain.
Discounts
1 2 3 4 5 6 7 8 9
Card number 10 47 52 47 59 66 54 51 47 45 32
The relative frequency for a 10% discount is []
The total number of customers is 500. We need to find the number of customers who received each discount.
For a 10% discount, customers received cards labeled 2, 4, 8, or 10. The total number of customers who received one of these cards is:
47 + 47 + 51 + 45 = 190
Therefore, the relative frequency for a 10% discount is:
190 / 500 = 0.38 or 38%
For a 40% discount, customers received cards labeled 7 or 9. The total number of customers who received one of these cards is:
54 + 47 = 101
Therefore, the relative frequency for a 40% discount is:
101 / 500 = 0.202 or 20.2%
For a 25% discount, customers received cards labeled 1, 3, 5, or 6. The total number of customers who received one of these cards is:
52 + 59 + 66 + 32 = 209
Therefore, the relative frequency for a 25% discount is:
209 / 500 = 0.418 or 41.8%
Based on the table, it seems that a large percentage of customers are receiving the 25% discount (41.8%). If the manager of the store wants approximately half of the customers to receive this discount, it may not be appropriate to use this method. However, it is also important to consider other factors, such as the store's profit margins and overall sales volume, when determining the best discount strategy.
Identify the total number of customers, which is given as 500 in the table.
For the 10% discount, add up the number of customers who received cards labeled 2, 4, 8, or 10. In the table, the corresponding counts are given as 47, 47, 51, and 45, respectively. Add these numbers together to get the total number of customers who received a 10% discount:
47 + 47 + 51 + 45 = 190
To find the relative frequency for a 10% discount, divide the number of customers who received a 10% discount (190) by the total number of customers (500):
190 / 500 = 0.38 or 38%
Therefore, the relative frequency for a 10% discount is 38%.
Repeat steps 2 and 3 for the other two discounts. For the 40% discount, add up the number of customers who received cards labeled 7 or 9, which are given as 54 and 47 in the table, respectively:
54 + 47 = 101
Then, find the relative frequency for a 40% discount by dividing the number of customers who received a 40% discount (101) by the total number of customers (500):
101 / 500 = 0.202 or 20.2%
Therefore, the relative frequency for a 40% discount is 20.2%.
Finally, for the 25% discount, add up the number of customers who received cards labeled 1, 3, 5, or 6, which are given as 52, 59, 66, and 32 in the table, respectively:
52 + 59 + 66 + 32 = 209
Then, find the relative frequency for a 25% discount by dividing the number of customers who received a 25% discount (209) by the total number of customers (500):
209 / 500 = 0.418 or 41.8%
Therefore, the relative frequency for a 25% discount is 41.8%.

Sharon wants to switch from cable to satellite TV. She calls Great Vista Satellite to get a quote. After looking at her cable bill, the salesperson explains that they can provide the same 300 channels Sharon has for $0.20 less per channel. If she switches, her monthly satellite bill will come to $180.
Answer:
If Sharon has 300 channels with her cable service, then her monthly cost is calculated as follows:
300 channels × $0.20 per channel = $60
This means that Sharon's current cable bill is $60 per month. If she switches to Great Vista Satellite, her monthly cost will be $180, which is $120 more than her current bill. This increase in cost can be represented by the equation:
$120 = 300 channels × $0.20 per channel × m
where "m" is the number of months Sharon has to subscribe to the satellite service to break even.
Simplifying the equation, we get:
m = $120 ÷ ($0.20 × 300 channels) = 2
Therefore, Sharon will have to subscribe to the satellite service for 2 months to break even. After that, she will start saving $0.20 per channel per month compared to her cable service.
Percy took a total of 12 quizzes over the course of 4 weeks. How many weeks of school will Percy have to attend this quarter before he will have taken a total of 15 quizzes? Assume the relationship is directly
Answer:
5 weeks
Step-by-step explanation:
To solve this problem, we can use the idea of proportionality. We know that the number of quizzes Percy takes is directly proportional to the number of weeks he attends school. This means that we can set up a proportion:
12 quizzes / 4 weeks = 15 quizzes / x weeks
We can cross-multiply to get the following:
12x = 60
Then we can solve for x:
x = 60/12 = 5
Therefore, Percy will have to attend 5 weeks of school to take a total of 15 quizzes.
