Answer:
1,172.3 cm³
Step-by-step explanation:
Find the volume of one rod, then divide the total volume of steel used by the volume of one rod. The volume of one rod is
V = (πd²/4)h
d = 4 cm
h = 20 cm
Plugin the numbers and get V in cm³, then divide the given total volume of 28,134.4 cm³ by V. If the result is not an integer, then round down.
Add
20 + 4 = 24
Then
28,134.4 ÷ 24 = 1172.26
Rounded to the nearest 0.1 or the Tenths Place = 1,172.3
Therefore, 1,172.3 rods will be made per hour.
Which of the following represents the range of the function table?
A. {-3, 1, 7}
B. {-6, -3, -2, 1, 5, 7}
C. {0, 1, 2, 3, 4, 5, 6}
D. {-6, -2, 5}
The range of the given table would be set of all possible y-values as {-6, -2, 5} which is the correct answer would be an option (D).
What are the domain and range of the function?The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.
We have been given that table as:
x y
-3 -6
1 -2
7 5
As per the given table, the required solution would be as:
The range of a function is the set of all possible output values of the function. In this case, the output values of the function are the y-values in the table. The range of the function table is the set of all possible y-values, which in this case is {-6, -2, 5}.
Therefore, the range of the function table is therefore -6 to 5.

Answer:
Step-by-step explanation:
I don't think this can be done without the diagram. You do not know what HD is opposite. I will take a guess that it is opposite TU which makes TU = 220 because both H and D are midpoints and that makes TU twice as large as HD.
If this is incorrect, post the diagram.

Answer:
1. 18
2. 72
3. 90%
Step-by-step explanation:
For number 1
To find percentage you multiply the total number of kids with the percentage.
To do this you have to convert the percent into a decimal by moving the dot 2 times from its original location Ex. 20% = .20 as 20 would look like 20.00 in decimal form.
So .20 x 90 = 18
For number 2
Subtract 18 and 90 to find the remanding kids
For number 3
Divide 72 and 90. Make sure the lower number is being divided.
The answer you will get is .8 so move the decimal back two times because you are converting it to a percentage."
You will then get 80.00 as an answer then from there turn it to a percentage
80%

David has counters. Lisa has 5 more counters than David. Samia has 4 times as many counters as David. The total number of counters is . Write a formula for in terms of . Give your answer in its simplest form.
Answer:
if 'c' equals number of counters, the answer is 6c + 5
Step-by-step explanation:
david has 'c'
lisa has '5+c'
samia has '4c'
add all terms together: c + 5 + c + 4c = 6c + 5
The formula for the total number of counters in terms of x is T = 6x + 5
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
Let's start by expressing the number of counters Lisa has in terms of x. We know that Lisa has 5 more counters than David, so:
Lisa = David + 5
Lisa = x + 5
Next, we need to express the number of counters Samia has in terms of x. We know that Samia has 4 times as many counters as David, so:
Samia = 4 × David
Samia = 4x
Finally, we can express the total number of counters in terms of x by adding up the number of counters each person has:
T = David + Lisa + Samia
T = x + (x + 5) + 4x
T = 6x + 5
Therefore, the formula for the total number of counters in terms of x is T = 6x + 5.

Explain how to use the distributive property to simplify: -2(x + 5) ?
Answer:
-2x-10
Step-by-step explanation:
Distributive Property is basically a term for opening parentheses. So, in your case -2(x+5) we would multiply x and 5 by -2. X times -2 is -2x and 5 times negative 2 is -10. -2x-10 would be your final answer.
[tex]\huge\bold{ANSWER:}[/tex]
-2x-10
[tex]\bf{EXPLANATION:[/tex]
Hi there!
Here's what the Distributive Property states:
a(b+c)=ab+ac
So, we take a number outside the parentheses, and "distribute" it.
In this case, we should distribute -2:
-2(x+5)
-2x-10 (a negative times a negative is a positive)
Hope it helps!
Enjoy your day!

Braden's credit card balance was $162. If
he charges $54 then makes a $75 payment,
find the balance on his card.
Answer:the answer is 33
Step-by-step explanation:
The balance on the credit card will be $33.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that Braden's credit card balance was $162. He charged $54 then makes a $75 payment the balance amount will be calculated as below:-
Balance = 162 - 75 - 54
Balance = 162 - 129
Balance = $33
Therefore, the balance on the credit card will be $33.
