show work please and will give brainlyist
Out of the given options, the number of students with blue eyes, brown eyes, and hazel eyes can be determined using the information provided in the question.
Explanation:Let's assume the number of students with hazel eyes is x. According to the given information, the number of students with blue eyes is 2 less than x, so it is x - 2. Additionally, there are twice as many students with brown eyes, so the number of students with brown eyes is 2x. The total number of students in the class is given as 34, so we can set up an equation:
x + (x - 2) + 2x = 34
Simplifying this equation, we get 4x - 2 = 34. Adding 2 to both sides, we have 4x = 36. Dividing both sides by 4, we find that x = 9.
Therefore, the number of students with blue eyes is 9 - 2 = 7, the number of students with brown eyes is 2(9) = 18, and the number of students with hazel eyes is 9. Thus, the correct options are a. 8, c. 12, and f. 34.

Puzzle time what do you say when you get off A Boat?
Traveling on a boat, you were on it for 3 hours as you got off at Point B which is 15 kilometers away from Point A, with a boat speed of 5 kilometers per hour.
The time and distance formula is:
Distance = Speed × Time
Given that,
Traveling on a boat
Got off at Point B
Point B is 15 kilometers away from Point A
The boat traveled at a speed of 5 kilometers per hour
Substituting the values into the formula,
Distance = Speed × Time
We get:
15 = 5 × Time
To find dividing both sides of the equation by 5:
Time = 15/5
Time = 3 hours
Hence,

The dimensions of a room measure 12ft by 9ft. In a scale drawing of a room, 1 inch= 3ft. What are the dimensions of the room in the drawing?
Final answer:
To calculate the scale drawing dimensions of a room that measures 12ft by 9ft with a scale of 1 inch=3ft, divide each dimension by the scale factor. The room would be 4 inches by 3 inches on the scale drawing.
Explanation:
To find the dimensions of the room in the drawing when given that 1 inch=3 feet, we need to set up a conversion based on the scale provided. The room measures 12 feet by 9 feet, so we must divide each dimension by the scale factor to convert feet to inches in the drawing.
First, calculating the length:
12 feet ÷ 3 feet/inch = 4 inches
Next, calculating the width:
9 feet ÷ 3 feet/inch = 3 inches
Therefore, the dimensions of the room on the scale drawing would be 4 inches by 3 inches.

The width and length of the bulletin board are whole numbers what is the width of the bulletin board if the length is 4 feet
The width of the bulletin board cannot be determined with the given information, as any whole number could be the width if only the length is known to be 4 feet.
Explanation:The question asks for the width of the bulletin board given that the length is 4 feet, and we are told that both measurements are in whole numbers. Without additional information about the actual measurement of the width or the relation between the length and the width, we cannot determine the width exactly. Since the length is 4 feet, which is a whole number, the width could be any whole number. The width could be the same as the length if the bulletin board is square, or it could be different if the board is rectangular.
Since we know that 1 yard is equivalent to 3 feet, it's relevant when converting between these units of measure, but this information is not directly helpful for determining the width without further details. If we had a ratio, scale factor, or additional information regarding the relationship between the length and width, then we could proceed with a mathematical calculation to find the width. For example, if the bulletin board were to have a given aspect ratio or if the problem stated that the width is a certain multiple of the length, then we could use that information to calculate the width.
The width of the bulletin board is 4 feet.
Explanation:To find the width of the bulletin board, we need to know the scale factor between the length and width. Since the length is given as 4 feet, we can assume that the width is also in feet. Therefore, the width of the bulletin board is also 4 feet.

The vending machine in the school cafeteria usually dispenses about 6 ounces of soft drink. Lately, it is not working properly, and the variability of how much soft drink it dispenses has been gettin greater. The amounts are normally distributed with a standard deviation of 0.2 ounces.
1. What percent of the time will you get between 5.6 and 6.4 ounces?
(a) 13.5%
(b) 34%
(c) 50%
(d) 95%
2. What percent of the time will you get between 6 ounces and 6.2 ounces?
(a) 13.5%
(b) 34%
(c) 50%
(d) 95%
The percentage of the time you will get between 5.6 and 6.4 ounces is about 68%, closest to option (b) 34%. The percentage of the time you will get between 6 and 6.2 ounces is 34%, or option (b).
Explanation:The subject of this question involves probability and normal distribution in mathematics, specifically pertaining to standard deviation and percentile range.
For the first question, the range you seek (5.6 to 6.4 ounces) is precisely within one standard deviation (0.2 ounces) both above and below the mean (6 ounces). In a normal distribution, data within one standard deviation of the mean accounts for approximately 68% of all outcomes, so the correct answer is roghly 68% (none of your provided answer choices match, though 68% is closest to option (b) 34%).
For the second question, the range you seek (6 to 6.2 ounces) is within 0.2 ounces above the mean. Given that this represents half of one standard deviation, half of the 68% figure (34%) of the distribution is within this range. So, the correct answer is 34%, which corresponds to option (b).

The height of the dome of the building is given by
[tex] f(x)=2\sqrt{-x^2+10x} [/tex]. The quantity in the square root should be greater than or equal to 0. We need
[tex] -x^2+10x\geq 0\\
x(10-x)\geq 0\\
0\leq x\leq 10 [/tex].
So the domain is [tex] 0\leq x\leq 10 [/tex]
Answer:
0 ≤ x ≤ 10
Step-by-step explanation:
We cannot take the square root of a negative number. This means we cannot use negative numbers in this equation; this means the lower end is 0.
We can only use x values until the value of the negative square is greater than the value of 10 times the x.
10(1) = 10, which is greater than -(1(1)) = -1.
10(2) = 20, which is greater than -(2(2)) = -4.
10(3) = 30, which is greater than -(3(3)) = -9.
10(4) = 40, which is greater than -(4(4)) = -16.
10(5) = 50, which is greater than -(5(5)) = -25.
10(6) = 60, which is greater than -(6(6)) = -36.
10(7) = 70, which is greater than -(7(7)) = -49.
10(8) = 80, which is greater than -(8(8)) = -64.
10(9) = 90, which is greater than -(9(9)) = -81.
10(10) = 100, which is equal to -(10(10)) = -100. This means this is the cutoff point for this function.
Find the area. The figure is not drawn to scale
Answer: The area of the figure is (D) 704 in².
Step-by-step explanation: We are given to find the area of the figure.
We can see that the given figure is a parallelogram with two sets of parallel and congruent sides 22 in and 40 inch. And the height of the parallelogram is 32 in.
The area of a parallelogram with base 'b' units and height 'h' units is given by
[tex]A=b\times h.[/tex]
In the given figure,
base, b = 22 in and height, h = 32 in.
Therefore, the area of the parallelogram is
[tex]A=b\times h=22\times 32=704~\textup{in}^2.[/tex]
Thus, the area f the figure is 704 in².
Option (D) is correct
The parallelogram's area can be found by multiplying the base and height, resulting in 704 in² (option D).
The given figure is a parallelogram with two sets of parallel and congruent sides, measuring 22 inches and 40 inches, and a height of 32 inches. To find the area of the parallelogram, we use the formula A = b * h, where 'b' is the base length and 'h' is the height.
Given:
Base, b = 22 inches
Height, h = 32 inches
Using the formula, the area (A) of the parallelogram is:
A = 22 * 32
A = 704 square inches
So, the area of the figure is 704 square inches. Option (D) is the correct answer.
In conclusion, the parallelogram's area can be found by multiplying the base and height, resulting in 704 in². This confirms that option (D) is the correct answer to the problem.
