To calculate the amount Josef will pay for the shirt on sale, we need to consider the discount of 15% off the regular price. Several expressions can be used to calculate the final amount, including options (a), (b), (c), and (f).
These expressions involve manipulating the regular price of the shirt and the discount percentage to determine the final price after the discount is applied.
(a) The expression "5-0.855" is not a valid calculation for the amount Josef will pay. It seems to be a typographical error.
(b) The expression "s-0.15s" is a valid expression to calculate the amount Josef will pay. It represents the regular price (s) minus the discount of 15% of the regular price.
(c) The expression "0.855" is not a valid calculation for the amount Josef will pay. It seems to be the result of mistakenly subtracting 15% from 100%.
(d) The expression "1.155" is not a valid calculation for the amount Josef will pay. It seems to be the result of mistakenly adding 15% to 100%.
(e) The expression "(1+0.15)s" is not a valid calculation for the amount Josef will pay. It seems to mistakenly add 15% to the regular price.
(f) The expression "(1-0.15)s" is a valid expression to calculate the amount Josef will pay. It represents the regular price (s) multiplied by the factor of (1-0.15), which accounts for the 15% discount.

Tori and 2 of her friends each listened to music for 4/5 of an hour. How long did they listen to music in all
Tori and her two friends listened to music for a total of 2 hours and 2/5 of an hour (or 2.4 hours) in all.
Tori and her two friends each listened to music for 4/5 of an hour.
To find out how long they listened to music in total, we need to multiply the duration by the number of people.
Since Tori and her two friends listened to music for the same amount of time, we can simply multiply the duration by 3 (to account for Tori and her two friends).
Duration per person: 4/5 hour
Total duration: (4/5) [tex]\times[/tex] 3 = 12/5 hour
To simplify the fraction, we can express 12/5 as a mixed number.
Since 5 goes into 12 evenly twice, with a remainder of 2, the total duration can be written as 2 2/5 hours.

Select the correct answer. Amy gets a new kennel for her dog. A sketch of the kennel is shown here. If the roof is in the shape of a triangular prism (bottom face included), what is the surface area of the roof of the kennel, including the bottom face?
A. 60. 24 square feet
B. 58. 96 square feet
C. 53. 96 square feet
D. 51 square feet
The surface area of the roof of the kennel, including the bottom face, is 51 square feet. The correct answer is D. 51 square feet.
To calculate the surface area of the roof of the kennel, including the bottom face, we need to find the area of the triangular prism. The surface area of a prism can be calculated by adding the areas of all its faces. In this case, the triangular prism has two triangular faces and three rectangular faces.
First, we calculate the area of the triangular faces. The formula for the area of a triangle is (base * height) / 2. Since the triangular prism has a bottom face included, the triangular faces share the same base. Let's assume the base of the triangle is 6 feet and the height is 8 feet. The area of one triangular face is (6 * 8) / 2 = 24 square feet. Since there are two triangular faces, the total area of the triangular faces is 2 * 24 = 48 square feet.
Next, we calculate the area of the rectangular faces. Let's assume the length of the kennel is 8 feet, the width is 4 feet, and the height is 6 feet. The area of one rectangular face is length * width, which is 8 * 4 = 32 square feet. Since there are three rectangular faces, the total area of the rectangular faces is 3 * 32 = 96 square feet.
Finally, we add the areas of the triangular faces and rectangular faces to get the total surface area of the roof: 48 + 96 = 144 square feet. However, since the question asks for the surface area of the roof, including the bottom face, we subtract the area of the bottom face, which is the same as the area of one rectangular face: 32 square feet. Thus, the final surface area is 144 - 32 = 112 square feet, which corresponds to option D: 51 square feet.

Thomas and candice both mowed lawns this summer. thomas mowed 35 lawns and received 150 in tips. candice mowed 30 lawns but got 275 in tips. they both charged the same per lawn . how much did they charge to mow a lawn?
Answer: To determine how much Thomas and Candice charged to mow a lawn, we can compare their total earnings (including tips) to the number of lawns they mowed.
Thomas mowed 35 lawns and received $150 in tips. Let's denote the amount Thomas charged to mow a lawn as "x."
Total earnings for Thomas = Earnings from lawns + Tips
Total earnings for Thomas = (35 * x) + $150
Similarly, Candice mowed 30 lawns and received $275 in tips. Let's denote the amount Candice charged to mow a lawn as "y."
Total earnings for Candice = Earnings from lawns + Tips
Total earnings for Candice = (30 * y) + $275
Since both Thomas and Candice charged the same amount per lawn, we can set their total earnings equations equal to each other:
(35 * x) + $150 = (30 * y) + $275
Now, we can solve this equation to find the amount they charged per lawn.
35x + $150 = 30y + $275
Rearranging the equation:
35x - 30y = $275 - $150
35x - 30y = $125
To simplify the equation, we need to know the specific values of x and y, which are the amounts they charged per lawn. Without additional information, we cannot determine the exact values of x and y or how much they charged to mow a lawn.
The heights of mature maple trees are approximately normally distributed with a mean of 80 feet and a standard deviation of 12.5 feet. What proportion of mature maple trees are between 60 and 90 feet? (round to the nearest whole percent)
73% of mature maple trees are between 60 and 90 feet. The required percentage is 73%
Given that the heights of mature maple trees are approximately normally distributed with a mean of 80 feet and a standard deviation of 12.5 feet.
The formula for the z-score is given by:
z = (X - μ)/σ, where X = 60, μ = 80, and σ = 12.5
Substitute the values, we get
z = (60 - 80) / 12.5
= -1.6
The z-score for 60 feet is -1.6.
The formula for the z-score is given by:z = (X - μ)/σ, where X = 90, μ = 80, and σ = 12.5
Substitute the values, we get
z = (90 - 80) / 12.5= 0.8
The z-score for 90 feet is 0.8.
To find the proportion of mature maple trees between 60 and 90 feet, we need to find the area under the standard normal curve between z = -1.6 and z = 0.8.
Using the standard normal distribution table or calculator, we can find the area under the curve as follows:
Area = 0.7881 - 0.0516= 0.7365
Therefore, the proportion of mature maple trees between 60 and 90 feet is 73% (rounded to the nearest whole percent).
Hence, the correct answer is option (D).

How much did the baker pay for the 8 trays of brand
The baker paid approximately R15.08 for each tray of Brand A.
Understanding Word ProblemLet:
x = price of each tray of Brand A
y = price of each tray of Brand B
Given that the prices are in the ratio 4:7, we can write the equation:
x/y = 4/7
To find the individual prices of Brand A and Brand B, we can introduce a constant k:
x = 4k
y = 7k
The total cost of 8 trays of Brand A (8x) and 6 trays of Brand B (6y) is R279.45:
8x + 6y = 279.45
Substituting the expressions for x and y:
8(4k) + 6(7k) = 279.45
32k + 42k = 279.45
74k = 279.45
Dividing both sides by 74:
k = 279.45 / 74
k ≈ 3.77
Now we can find the price of each tray of Brand A:
x = 4k ≈ 4 * 3.77 ≈ R15.08
Therefore, the baker paid approximately R15.08 for each tray of Brand A.

Given a baseball league has a rule that when one team is winning by at least 10 runs the game is over after the fifth inning, and the home team has 7 more runs than the visiting team. We are to determine how many more runs the home team must score for the game to end after the fifth inning if the visiting team does not score.
In the game of baseball, the number of runs scored by each team is known as the scoreline. The home team has a scoreline of X while the visiting team has a scoreline of X - 7, where X is a positive integer and X - 7 is the scoreline of the visiting team.
Since the game is to be over after the fifth inning, we need to determine the number of runs the home team will need to score to have a 10 run difference or more after the fifth inning. Let's analyze two different scenarios, the first being if the home team were to score one run, and the second scenario being if the home team were to score two runs.
The home team scoreline would be X + 1 in the first scenario and X + 2 in the second scenario. In both cases, the visiting team does not score any additional runs. Thus, the scoreline of the visiting team remains X - 7 in both scenarios.
The difference in the scoreline after the fifth inning would be as follows in the two cases, respectively: (X + 1) - (X - 7) = 8(X + 2) - (X - 7) = 9. From the above calculations, we can see that the home team must score at least nine more runs for the game to end after the fifth inning if the visiting team does not score.
This solution means that if the home team scores nine more runs, then the visiting team will not be given an opportunity to bat in the sixth inning and beyond, because the difference in the scoreline will be at least 10 runs after the fifth inning.

A cylinder and a cone have the same height and the same base areas. If the volume of the cylinder is 66 cubic inches, what is the volume of the cone? (Use 3. 14 for Pi)
Answer:
The volume of the cone is 22 cubic inches.
Step-by-step explanation:
To find the volume of the cone, we need to use the formula for the volume of a cone:
Volume of a cone = (1/3) * π * r^2 * h
Given that the height and base area of the cylinder and cone are the same, we can assume that the radius of the cylinder's base is equal to the radius of the cone's base.
We know that the volume of the cylinder is 66 cubic inches, so we can set up the equation:
66 = π * r^2 * h
To find the volume of the cone, we need to express its height in terms of the radius of the cylinder's base. The height of the cone will be equal to the height of the cylinder.
Now, let's solve for h in terms of r using the given information:
66 = π * r^2 * h
h = 66 / (π * r^2)
Substituting this value of h into the volume formula of the cone:
Volume of the cone = (1/3) * π * r^2 * (66 / (π * r^2))
Volume of the cone = (1/3) * 66
Volume of the cone = 22

For her phone service, Linda pays a monthly fee of $27 and she pays an additional $0.07 per minute of use The least she has been charged in a month is $129.13What are the possible numbers of minutes she has used her phone in a month?
Therefore, the possible numbers of minutes Linda has used her phone in a month are 1459 minutes or more.
To determine the possible number of minutes Linda has used her phone in a month, we can set up an equation based on the given information.
Let's assume the number of minutes Linda has used her phone in a month is represented by 'm'.
The total charge for the phone service consists of the monthly fee of $27 plus the additional charge of $0.07 per minute:
Total charge = $27 + $0.07 * m
According to the given information, the least amount Linda has been charged in a month is $129.13. So we can set up the following equation:
$27 + $0.07 * m ≥ $129.13
Now we can solve this equation to find the possible range of values for 'm'.
$0.07 * m ≥ $129.13 - $27
$0.07 * m ≥ $102.13
m ≥ $102.13 / $0.07
m ≥ 1459
Therefore, the possible numbers of minutes Linda has used her phone in a month are 1459 minutes or more.

if BAT is congruent to DOG and angle B equals 14 angle G equals 29 and angle O is equal to 10 X +7 find X and angle O
The value of X is 7/10 and the measure of angle O is 14. Angle O must also be equal to 14, as it corresponds to angle B in the congruent triangle DOG.
To find the value of X and the measure of angle O, we need to use the information provided about the congruent triangles BAT and DOG and the measures of angles B, G, and O.
Given that BAT is congruent to DOG, we know that their corresponding angles are equal.
From the given information, angle B is equal to 14 and angle G is equal to 29.
Therefore, angle O must also be equal to 14, as it corresponds to angle B in the congruent triangle DOG.
We are also given that angle O is equal to 10X + 7.
Setting up an equation, we have:
10X + 7 = 14
To solve for X, we subtract 7 from both sides:
10X = 14 - 7
10X = 7
Dividing both sides by 10:
X = 7/10
Thus, X is equal to 7/10.
Therefore, the value of X is 7/10 and the measure of angle O is 14.
