Cole is building a model rocket in science class. He selects the rocket parts from a set of solid cylinders and cones made from metal. Cole wants to build a rocket with the dimensions shown. For safety purposes, the maximum lift-off weight of each rocket is 10 pounds. Will Cole’s rocket meet the requirement for launch?
Part A
What will be the total length of the assembled rocket? Explain how you found your answer.
Part B
What is the approximate volume of the rocket. Use 3.14 for π. Explain.
Part C
If Cole’s rocket parts are made of aluminum weighing 0.006 pound per cubic centimeter, will Cole be able to launch his rocket? Explain.
Answers
A.
30 since 25 + 5 = 30
The maximum lift-off weight of each rocket is 10 pounds thus, Cole’s rocket doesn't meet the requirement for launch.
What is the volume of a cylinder?The volume of the cylinder is the product of the height, pie, and square of the radius.
The volume of the cylinder = [tex]\pi r^{2} h[/tex]
Part A
The total length of the assembled rocket will be the length of the cone and the cylinder.
Height of the cone
[tex]\sqrt{l^{2} -r^{2} } \\\\\sqrt{5^{2} -4^{2} } \\[/tex] = 3 cm
The total length of the assembled rocket = 25 + 3 = 28cm
Part B
The volume of the rocket is the combined volume of the cone and cylinder.
= [tex]\pi r^{2} h[/tex] + 1/3[tex]\pi r^{2} h[/tex]
= 4/3 [tex]\pi r^{2} h[/tex]
= 4/3 × 3.14 × 16 × 28
= 1875.62 cubic cm
To convert cm into pound
1875.62 cubic cm = 4.135 pound
Part C
If Cole’s rocket parts are made of aluminum weighing 0.006 pounds per cubic centimeter.
Then 1875.62 cubic cm × 0.006
= 11.253
For safety purposes, the maximum lift-off weight of each rocket is 10 pounds. but Cole’s rocket doesn't meet the requirement for launch.

Consider the following statement: Two sets of data with the same mean will also have the same variability. Do you agree or disagree with this statement? Explain.
Answers
The statement is false and same mean can have different variability
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the mean of the data be represented as M
Now , The mean is a measure of central tendency that represents the average value of a set of data, but it does not provide information about the variability or spread of the data.
For example, consider the following two sets of data:
Set 1: 1, 2, 3, 4, 5 (mean = 3)
Set 2: 0, 2, 3, 4, 6 (mean = 3)
Both sets have the same mean of 3, but Set 1 has a smaller range (4) compared to Set 2 (6). The range is a measure of variability that represents the difference between the maximum and minimum values in a set of data.
Hence , two sets of data with the same mean can have different variability,

What is the value of x and the measure of ∠LNM, respectively?

B. x = 155 ; ∠LNM = 25
C. x = 45 ; ∠LNM = 135
D. x = 135 ; ∠LNM = 45
Pls dont put nonsense answer thank you
Answers
Linear pair of angles are of 180°. So,
45°+3x = 180°
=> 3x = 180°-45°
=> 3x = 135°
=> x = 135°/3
=> x = 45°
Answer:
Option C: x = 45, ∠LNM = 135
Step-by-step explanation:
Both the angles are supplementary which means they both add up to a straight angle or 180°;
45 + 3x = 180
=> First subtract 45 on each side of "="
3x = 135
=> Now divide both sides of "=" by 3
x = 45Now to find measure of angle LNM, substitute in 45 for x
3x = ∠LNM
3(45) = ∠LNM
135 = ∠LNMHope this helps!

C. x = 50 ; ∠WZX = 41
D. x = 41 ; ∠WZX = 50
Answers
Answer:
x = 43
Step-by-step explanation:
Supplementary angles = 180°
So,
(3x + 17) + (x - 9) = 180°
Combine like terms:
4x + 8 = 180
Subtract 8 on both sides
4x = 172
Divide 4 on both sides
x = 43

What is the value of x?
Answers
Answer:
x = 24
Step-by-step explanation:
(2x - 4) + (3x + 5) + (2x + 11) = 180°
Combine like terms:
7x + 12 = 180
Subtract 12 on both sides:
7x = 168
Divide 7 on both sides:
x = 24
