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.
How to solveThe 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.
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.

Find the height of each figure.
(Triangle)
The area of the triangle is 6,460 inches squared.
The base is 136 inches and 196 inches. Find the missing height of the figure which is X inches.
The missing height of the triangle is h = 66 inches
Given data ,
Let's denote the missing height of the triangle as "h" inches.
The formula for the area of a triangle is given by:
Area = (1/2) * base * height
Given that the area of the triangle is 6,460 inches squared and the base is either 136 inches or 196 inches, we can set up two equations to solve for "h".
For the base of 136 inches:
Area = (1/2) * 136 * h
6460 = 68h
h = 6460 / 68
h ≈ 95 inches
For the base of 196 inches:
Area = (1/2) * 196 * h
6460 = 98h
h = 6460 / 98
h ≈ 66 inches
Hence , the height of the triangle is h = 66 inches or 95 inches

The height of the low tide at 7 AM was 45.06 feet.
Given that, the high tide at midnight was 15.42 feet.
A nearing hurricane tripled the tide height. At low tide it went down by 1.2 feet at 7 AM.
We need to find the height of the low tide at 7 AM,
So,
When the hurricane is near the height of the tide is triples so the height is 15.42 × 3 = 46.26 feet
Now, at low tide it went down by 1.2 feet at 7 AM.
so, the height will be = 45.26 feet - 1.2 feet = 45.06 feet

The number of times on the hour in 3 days at least two owls will not hoot obtained using number theory are 69 times.

Find the measure of ∠GJK. (I need the answer as fast as possible)
Answer:
∠ GJK = 102°
Step-by-step explanation:
(2x + 92) and (3x + 63) are same- side interior angles and sum to 180° , so
2x + 92 + 3x + 63 = 180
5x + 155 = 180 ( subtract 155 from both sides )
5x = 25 ( divide both sides by 5 )
x = 5
Then
∠ GJK = 2x + 92 = 2(5) + 92 = 10 + 92 = 102°
What are the rectangular coordinates of the polar coordinates?
The rectangular coordinate from the given polar coordinate is (2.73, -0.73)
What are the rectangular coordinatesTo find the rectangular coordinate from the polar coordinates, we can rewrite this as;
x = r cosθ
y = r sinθ
r = The distance from the origin to the pointθ = The angle the line segment connects with the point and the origin makes along the positive axis.x = r cosθ
Let's substitute the values into it;
x = (2√2)* cos(-π/12)
x =(2√2)cos(-15)
x = √3 + 1
x = 2.73
y = r sin θ

5x - y = 77

Oki and Stephen are making bags of trail mix to sell. Oki’s trail-mix recipe requires 3 cups of nuts and 3 cups of dried fruit per bag. Stephen’s trail-mix recipe requires 4 cup of nuts and 2 cups of dried fruit per bag. Together, they want to make as many bags of trail mix as possible. They have exactly 120 cups of nuts and 90 cups of dried fruit. Find the maximum number of bags of trail mix Oki and Stephen can make together.
A. write a system of inequalities
B. Graph and find coordinates of the vertices of the feasible region.
C. Find the maximum number of bags of trail mix oki and stehpen can make. How many of each type of recipe should they make to maximize the total number of bags
Answer: Oki should make 0 bags of her recipe, and Stephen should make 30 bags of his recipe.
For vertex (15,15):
3x + 4y = 120 --> 3(15) + 4(15) = 120 --> x = 15
3x + 2y = 90 --> 3(15) + 2y = 90 -->
Step-by-step explanation: A. To find the maximum number of bags of trail mix that Oki and Stephen can make together, we can use a system of inequalities to represent the constraints:
Let "x" be the number of bags of trail mix that Oki makes and "y" be the number of bags that Stephen makes. Then we have:
3x + 4y ≤ 120 (constraint on the number of cups of nuts)
3x + 2y ≤ 90 (constraint on the number of cups of dried fruit)
x ≥ 0 (non-negative constraint for Oki's bags)
y ≥ 0 (non-negative constraint for Stephen's bags)
B. To graph the feasible region, we can start by graphing the two constraint equations as lines:
3x + 4y = 120 (line A)
3x + 2y = 90 (line B)
We can find the x and y intercepts for each line:
For line A:
When x = 0, 4y = 120, y = 30 (y-intercept)
When y = 0, 3x = 120, x = 40 (x-intercept)
For line B:
When x = 0, 2y = 90, y = 45 (y-intercept)
When y = 0, 3x = 90, x = 30 (x-intercept)
Next, we can shade the region that satisfies all of the constraints. This region is below line A and to the left of line B, and is bounded by the x and y axes.
We can find the vertices of the feasible region by finding the intersection points of the two lines and the axes. These vertices are (0,0), (0,30), (15,15), and (30,0).
C. To find the maximum number of bags of trail mix that Oki and Stephen can make together, we need to evaluate the objective function at each vertex of the feasible region, and choose the vertex that maximizes the objective function.
The objective function is the total number of bags of trail mix:
z = x + y
Evaluating at the vertices:
Vertex (0,0): z = 0 + 0 = 0
Vertex (0,30): z = 0 + 30 = 30
Vertex (15,15): z = 15 + 15 = 30
Vertex (30,0): z = 30 + 0 = 30
The maximum value of the objective function occurs at vertices (0,30) and (15,15), where z = 30 bags of trail mix.
To determine how many of each type of recipe to make, we can substitute each vertex into the two constraint equations to find the corresponding values of x and y.
For vertex (0,30):
3x + 4y = 120 --> 3x + 4(30) = 120 --> 3x = -90 --> x = -30
3x + 2y = 90 --> 3(-30) + 2(30) = 90 --> y = 15
Therefore, Oki should make 0 bags of her recipe, and Stephen should make 30 bags of his recipe.
For vertex (15,15):
3x + 4y = 120 --> 3(15) + 4(15) = 120 --> x = 15
3x + 2y = 90 --> 3(15) + 2y = 90 -->

Alan owes the bank $11750. To repay his debt, he paid a fixed amount back to the bank each month. After 0.5 year(s), Alan's remaining debt was $6650. How much did Alan pay each month?
Alan paid an amount $850 to the bank each month to repay his debt.
The total amount that Alan paid back to the bank is equal to the initial amount that he owed minus the remaining amount after 0.5 year(s):
Total amount paid = Initial amount - Remaining amount
= $11750 - $6650
= $5100
We know that Alan paid this amount back over a period of 0.5 year(s), which is equivalent to 6 months.
Let x be the fixed amount that Alan paid back to the bank each month. Therefore, we can set up the following equation:
Total amount paid = Monthly payment × Number of months
$5100 = x × 6
x = $5100 / 6
= $850
Therefore, Alan paid an amount $850 to the bank each month to repay his debt.

The required, there were 644 premium seats and 646 regular seats sold.
Let x be the number of premium seats sold and y be the number of regular seats sold. Then we have two equations:
x + y = 1290 (total seats sold)
30x + 20y = 32240 (total revenue)
We can use the first equation to solve for y in terms of x:
y = 1290 - x
Substituting this into the second equation, we get:
30x + 20(1290 - x) = 32240
Simplifying and solving for x, we get:
x=644
So 644 premium seats were sold. Substituting this into the first equation, we get:
644+ y = 1290
y = 646
So 646 regular seats were sold.
