The main tank at an aquarium is a cylinder with a diameter of 203 ft and a height of 4 ft. What is its approximate volume? Use 3.14 for π. a. 129,400 ft3 b. 79,830 ft3 c. 236,560 ft3 d. 32,366 ft3
Answer: [tex]a.\ 129,400\ ft^3[/tex]
Step-by-step explanation:
The volume of a cylinder is given by:-
[tex]\text{Volume}=\pi r^2h[/tex]
Given: The diameter of cylinder = 203 ft.
Then the radius of the cylinder =[tex]\dfrac{203}{2}[/tex] ft.
The height of the cylinder = 4 ft.
Now, The volume of cylinder :will be -
[tex]\text{Volume}=(3.14)(\dfrac{203}{2})^2(4)=\\\\\Rightarrow\text{Volume}=129,396.26\approx129,400\ ft^3[/tex]

triangle abc is an isosceles right triangle. what is the measure of a base angle
Answer:
The measure of the base angle = 45°
Step-by-step explanation:
For better explanation of the solution see the attached figure of the diagram :
Given : An isosceles right triangle ABC
To find : Measure of the base angle
Solution :
Since, The triangle is right angle triangle.
⇒ m∠B = 90°
Also, ΔABC is an isosceles triangle
So, AB = BC
Now, Angles opposite to equal sides are equal
⇒ m∠A = m∠C
Now, Using Angles sum property of a triangle
⇒ m∠A + m∠B + m∠C = 180°
⇒ m∠C + 90° + m∠C = 180°
⇒ 2m∠C = 180° - 90°
⇒ 2m∠C = 90°
⇒ m∠C = 45°
Hence, The measure of the base angle = 45°

Which inequality represents the following sentence?
Twelve fewer than a number is at least 18.
12 + x ≤ 18
x – 12 ≥ 18 (This one correct?)
12 – x ≥ 18
x – 12 < 18,
Answer:
B) x - 12 ≥ 18.
Step-by-step explanation:
Given : Twelve fewer than a number is at least 18.
To find : Which inequality represents the following sentence?.
Solution : We have given
Twelve fewer than a number is at least 18.
Let the number be x .
According to question :
Twelve is less than a number x .
x - 12 ( negative sign used for fewer).
x - 12 ≥ 18.
Here we used greater than equal to sign because x- 12 is at least 18 mean is must be 18 or greater than 18.
Then equation become x - 12 ≥ 18.
Therefore, B) x - 12 ≥ 18.
State whether the relationship between the variables in the table is a direct variation, an inverse variation, or neither. If it is a direct or inverse variation, write a function to model it.
x=3,9,13,20
y=9,27,39,60
I know it's direct but how do I write a function model to it?,
The variation is a direct variation, and the function to model it is y = 3x
From the table, we can see that:
The y values are calculated by multiplying the corresponding x values by 3
Take for instance;
When x = 3, y = 9
When x = 9, y = 27
Using the above pattern, the function to model the table is y = 3x

Jake has shifted the (B) social-psychological context by moving to a quieter, more private space in the stadium to ask Diane a serious question, which changes the norms and atmosphere to match the situation's gravity.
Jake has changed the social-psychological context by moving from the stands to a quiet lounge. The social-psychological dimension of context includes status relationships among participants, roles, norms of the society or group, and the overall atmosphere like friendliness, formality, or gravity of the situation. By choosing to ask Diane a serious question in a quieter, more private environment, Jake is altering the norms and atmosphere to better suit the gravity of the conversation he intends to have, thus changing the social-psychological context.
How many solutions does the equation sin(4x)=1/2 have on the interval (0,2pi)?
Answer:
2 solutions
Step-by-step explanation:
Given the equation sin(4x)=1/2, to know the total number of solutions that the equation has within the interval (0,2π), we will need to solve for x first.
sin(4x)=1/2
4x = arcsin1/2
4x = 30°
x = 30/4
x1 = 7.5° (This angle lies in the first quadrant)
Since sine is positive in the second quadrant as well and the angle in the second quadrant is (180°-theta) where theta is 7.5°, therefore;
x2 = 180-7.5°
x2 = 172.5°
Therefore 7.5° and 172.5° are the two solutions of x that falls within the range (0,2π)

Unit rate is the quantity of an amount of something at a rate of one of another quantity.
If 1 gallon covers 350 square feet.
2.5 gallons will cover 875 square feet.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
Example:
A man can walk 8 miles in 2 hour
In one hour, the man can walk for 4 miles
We have,
One gallon covers 350 square feet.
This can be written as:
1 gallon = 350 square feet
Multiply both sides by 2.5.
2.5 x 1 gallon = 2.5 x 350 square feet
2.5 gallons = 875 square feet

A gray-scale digital camera with 1,000,000 pixels takes a picture (the picture is made of 1,000,000 parts and each part has a certain amount of gray). A histogram is made where the data is the amount of gray in each of these parts. The histogram looks bell-shaped with a mean of 125 gray levels and a standard deviation of 15.
How many pixels are brighter than 163 gray levels?
5000
10,000
160,000
50,000
To find the number of pixels brighter than 163 gray levels in a digital camera histogram, calculate the Z-score and use it to determine the percentage of values above that score, resulting in 160,000 pixels.
A gray-scale digital camera with 1,000,000 pixels has a histogram with a mean of 125 and standard deviation of 15 gray levels. To find the number of pixels brighter than 163 gray levels, first calculate the Z-score for 163: Z = (163 - 125) / 15. Then, use a Z-table or calculator to find the percentage of values above this Z-score, which corresponds to the number of pixels brighter than 163.
The answer to the question is 160,000 pixels brighter than 163 gray levels.

Three-fourths of an inch on a map equals 750 miles. what would one inch equal?
One inch on the map is equal to 1000 miles.
Explanation:To find what one inch would equal on the map, we can set up a proportion using the given information. We know that three-fourths of an inch on the map equals 750 miles. Therefore, the proportion would be: 3/4 inch = 750 miles. To find what one inch would equal, we can cross multiply and solve for the missing value:
3/4 inch * 1 inch = 750 miles * 1 inch
Simplifying, we get: 3/4 = 750 miles * 1 inch
Dividing both sides by 3/4, we get: 1 inch = (750 miles * 1 inch) / (3/4)
Simplifying further, we find that one inch on the map is equal to 1000 miles.
