What do I do I don’t know the answer
Answers
Answer:
B) 114.511m^3
Step-by-step explanation:
Formula of a cylinder is πr^2 x h
r = radius (half of diameter)
h = height
Since it is 3/4 full you only do 3/4 of the height so- 0.75 x 9.60 which equals 7.2
Half of the diameter is 2.25. 2.25^2 = 5.0625.
The volume of the cylinder = 5.0625π x 7.2
By solving this, you will get approximately 114.511 m^3 as your answer.

Answers
Answer:
x=15 degrees
Step-by-step explanation:
You know that the right angle is split in half to 45 degrees and 3x degrees. Because a right angle is equal to 90 degrees, 3x has to be equal to 45. Therefore, the equation will be 3x=45. You want to make x equal one so you have to divide 3 by each side. The equation will be x=45/3. Simplify that to get x=15. Therefore, x=15 degrees.

Prove that the roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k
Answers
The roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k
The equation is given as:
x^2 + (1 - k).x+k-3 = 0
For an equation to have real root, then the following must be true:
[tex]b^2 \ge 4ac[/tex]
In x^2 + (1 - k).x+k-3 = 0, we have:
a = 1
b = 1 - k
c = k - 3
So, we have:
[tex](1 - k)^2 \ge 4 * 1 * (k - 3)[/tex]
Evaluate
[tex]1 - 2k + k^2 \ge 4k - 12[/tex]
Collect like terms
[tex]k^2 - 2k - 4k + 1 + 12 \ge 0[/tex]
[tex]k^2 - 6k + 13 \ge 0[/tex]
Using a graphing calculator, the value of k is all real numbers
Hence, the roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k

Step-by-step explanation:
You have to look at it properly. It says "The value of SQUARE ROOTED K."
So all you have to do is square root them and whatever is in between 2.2 and 2.3 is ur answer. Ur answer 5 and 5.04.
The values of √k that lies between 2.2 and 2.3 is 5 and 5.04.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that √k falls between 2.2 and 2.3
For k = 1.49, √1.49 = 1.22 which is not between 2.2 and 2.3
For k = 4.8, √4.8 = 2.19 which is not between 2.2 and 2.3
For k = 5, √5 = 2.2 3which is between 2.2 and 2.3
For k = 5.04, √5,04 = 2.23 which is between 2.2 and 2.3
For k = 5.3, √5.3 = 2.302 which is not between 2.2 and 2.3
For k = 6, √6 which is not between 2.2 and 2.3

Step-by-step explanation:
9x_15+2x_3=180
11x_18=180
11x=180+18
11x=198
x=198÷11
x=18
Answer:
The angles are a linear pair.
x = 18
Step-by-step explanation:
The angles are a linear pair, meaning the angles add up to 180 degrees.
(9x - 15) + (2x - 3) = 180
11x - 18 = 180
11x = 198
x = 18

what is the mean median mode range of 3,14,7,12,4,9,16,4,8,20
Answers
First, order the number set from least to greatest:
3 , 4 , 4 , 7 , 8 , 9 , 12 , 14 , 16 , 20
Mean: You find the mean by combining all the terms, and dividing by the amount of the terms there are in the number set:
(3 + 4 + 4 + 7 + 8 + 9 + 12 + 14 + 16 + 20)/10
(97)/10 = 9.7
Mean: 9.7
Median: You find the median by first ordering the number set from least to greatest, and finding the middle number. Note that if there is a even number of numbers in the set, you find the mean with the two given median digits:
8 & 9 are the median numbers:
(8 + 9)/2 = (17)/2 = 8.5
Median: 8.5
Mode: The mode is the number(s) in the set that shows up the most:
Mode: 4 (shows up one more time than all other numbers)
Range: The range can be found by subtracting the least number from the greatest number in the number set:
Range: 20 - 3 = 17
Range: 17

if XYZ ~ RST, find RS
Answers
Answer:
RS = 38
Step-by-step explanation:
20x - 12 = 18x + 12
2x = 24
x = 12
3(12) + 2 = 38
The value of the side of triangle RS is equal to 38.
What is the similarity?If two objects are having the same shape then they will be termed as similar. So in mathematics, if two figures have the same shapes, lines or angles then they are called similar.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the sides of the triangle XYZ are, XY = 5x - 3, XZ = 60 and the sides of the triangle TR = 40, RS = 3x + 2.
The value of RS will be calculated as,
( 5x - 3 ) / ( 3x + 2 ) = ( 60 / 40 )
( 5x - 3 ) / ( 3x + 2 ) = ( 6 / 4 )
20x - 12 = 18x + 12
2x = 24
x = 12
RS = 3x + 2
RS = ( 3 x 12 ) + 2
RS = 36 + 2
RS = 38
Therefore, the value of the side of triangle RS is equal to 38.

Suzy makes 20 dollars an hour at her job. Bill only makes 10 dollars an hour but he has a starting bonus of 20. When will Suzy and Bill make the same amount of money for the same number of hours worked? How much will they both earn at the same time?
Answers
Answer:
2 hours
Suzy would earn $40
Bill will earn $40
they will both earn $80
Step-by-step explanation:
The total amount suzy earns is a function of the total hours worked. Let t represent time
total income of suzy = $20t eqn 1
Bill's income = starting bonus + variable pay
= $20 + $10t
We are looking for when they would earn the same amount :
20t = $20 + $10t eqn 2
collect like terms and solve for t
10t = $20
t = 2 hours
Substitute for t in either eqn 1 or 2
20(2) = $40
Suzy would earn $40
Bill will earn $40
they will both earn $80
