The balloon was flying at a height of 176.58 m .
The fundamentals of an object's motion, such as its position, velocity, or acceleration over time, are defined by kinematics equations of motion. An object's motion in one, two, and three dimensions is determined by these three equations of motion. One of three equations of motion can be used to calculate components like displacement (s), velocity (initial and final), time (t), and acceleration (a). The following are the three motion equations:
Initial formula: v = u + at
The second formula is s = ut + 0.5at2.
The third formula is v2 = u2 + 2as.
Let t stand for the duration of the metal bat's flight, s for the height at which the hot air balloon was traveling, and u for the metal bat's initial vertical velocity since it is simply dropped.
Given: The metal bat took 6 seconds to reach the ground.
With t = 12 and u = 0, the second equation of motion gives us s = 0*t + 0.5*9.81*162 = 176.58 m.

what does x have to measure to make the lines parallel?
PLEASE HELP ASAP
Answer:
23) 30°
24) 12°
Step-by-step explanation:
23) Lines will be parallel if the co interior angles are supplementary.
∠3 + ∠5 = 180°
3x+ 25 + 4x - 55 = 180
3x + 4x + 25 -55 = 180
Combine like terms,
7x - 30 = 180
Add 30 to both sides,
7x = 180 + 30
7x = 210
Divide both sides by 7,
x = 210 ÷ 7
x = 30
24) If the lines are parallel, then the alternate interior angles are congruent.
∠7 = ∠2
11x - 36 = 8x
Add 36 to both sides,
11x = 8x + 36
Subtract 8x from both sides,
11x - 8x = 36
3x = 36
x = 36 ÷ 3
x = 12°
A paper company needs to ship paper to a large printing business. The paper will be

A total of 24 boxes of paper were shipped weighing 1410 pounds altogether, the system of equations are X + Y = 24, and 45X + 75Y = 1410 and the variables that you use to write the system X = 13 and Y = 11.
What is pound?The primary unit of sterling is the pound (sign: £), while the term "pound" is also frequently used to refer to the British pound or pound sterling in foreign settings.
The oldest currency that is still in the circulation and has been used continuously since its origin is sterling. After US dollar, euro, and Japanese yen, it is currently fourth most traded currency on the foreign exchange market. It makes up basket of currencies used to determine the value of IMF special drawing rights along with the other three currencies and the renminbi. Sterling is also fourth-most-held reserve currency in the world's reserves as of mid-2021.
Let X equal number of small boxes
Let Y equal number of big boxes
The first equation is: X + Y = 24 ( this shows that total number of boxes = 24)
The second equation is: 45X + 75Y = 1410 ( this is because small box weighs 24 pounds and big box weighs 75 pounds. The total weight of small boxes is 45 times weight of each individual box. And the total weight of second boxes is equal to 75Y.
When you solve system, X = 13 and Y = 11

A group of friends take a tubing trip the company charges $15 for a regular tube and $7.50 for a cooler tube. Together they spent $360 to rent. How many of each tube did they rent?
The no. of regular tube costing $15 were 12 and the cooler tube costing $7.5 each were 24
What is a tubing?The entire family can participate in tubing. Change into swimwear, rent a tube and a life jacket, and float down the river—that it's easy. Numerous outfitters provide transportation to the best waterways and rent tubes from Blue Ridge to Columbus, via Helen and Columbus.
The total cost of rent on tube = $360
Price of regular tube = $15
Price of cooler tubes = $7.5
Let the no. of regular tubes be and cooler tubes be y
The equation forms
15x + 7.5y = 360 ...1
As we can notice regular tube is twice the price of cooler tubes, sthe the equation forms
2(7.5) = 15
This means when y = 2, x = 1
cross multiply them and we find
2/y = 1/x
x/y = 1/2
x = y/2 ...2
Putting the value of x in eq 1, we get
15(y)/2 + 7.5y = 360
7.5y + 7.5y = 370
15y = 360
y = 360/15
y = 24
Putting the value of y in eq 1, we get
15x + 7.5(24) = 360
15x + 180 = 360
15x = 360 - 180
15x = 180
x = 180/15
x = 12
Thus, The no. of regular tube costing $15 were 12 and the cooler tube costing $7.5 each were 24.

An urn has 10 balls that are identical except that 6 are white and 4 are red. a sample of 7 is selected randomly without replacement. what is the probability that exactly 5 are white and 2 are red? what is the probability that at least 5 of the balls are white?
The question tests on probability and combinations.
To obtain the probability for selecting exactly two red and 5 white urns is:
If Wi and Ri are events for selecting the ith ball, apply the multiplicative rule to obtain:
=P(W1∩W2∩W3∩W4∩W5∩R1∩R2)
= P(W1)P(W2|W1)P(W3|W1∩W2)P(W4|W1∩W2∩W3)P(W5|W1∩W2∩W3∩ W4)P(R1|W1∩W2∩W3∩W4∩W5)P(R2|W1∩W2∩W3∩W4∩W5∩R1)
=6/10×5/9×4/8×3/7×2/6×4/5×3/4
= 1/10
The probability is 1/10.
Alternatively, use the Bayes theorem. This uses combinations. To get the probability for exactly 5 white and 2 red, obtain the chance for selecting 5 white balls and 2 red balls; 6C5 and 4C2.
(6C5×4C2)/10C7 = 6×6/120 = 1/10
The probability for at least 5 balls is obtained by the probability of either selecting 5 or 6 balls.
Using combination;
(6C6 X6C5)/10C7 = (1x6)/120 = 6/120 = 1/20.

Total number of pencils and pens bought by Henry = 35.
What is the unitary method of problem solving?
The unitary technique, in its most basic form, is used to calculate the value of a single unit from a specified multiple. The unitary approach can be used to complete it. Additionally, after determining the value of a single unit, we can multiply that value by the number of units needed to determine the value of the additional units. The concept of ratio and proportion is mostly applied using this way.
Given, for every 3 pencils, number of pens bought = 2
Therefore, every 1 pencil, number of pens bought = 2/3
Thus, for 21 pencils, number of pens bought = (2/3)*21 = 14
Therefore, total number of pencils and pens bought by Henry = 21 + 14 = 35.

Step-by-step explanation:
Equation
f(x)= −3x^55+1
Given
x = - 10
Solution
You have to understand what f(x) means. When you put a value in for x, every x on the right is supplied with that value.
In this case I take the equation to mean what ever we are given in the brackets (in this case 10) is what goes into the x on the right. So the new equation is
f(-10) = -3*(-10)^5 + 1

f(-10) = -300000 + 1

∠J + ∠K + ∠L = 180° (angles in a triangle)
Substituting:
(7x + 2) + (8x) + (4x + 7) = 180
19x + 9 = 180

Which of the following is a solution to the equation
2x² + 4x = 3 + 3x² ?
A) -1
B)
0
C) 3
D) 6
===========================================================
Reason:
Let's check to see if choice A is the answer. We'll replace each x with -1
2x^2 + 4x = 3 + 3x^2
2(-1)^2 + 4(-1) = 3 + 3(-1)^2
2(1) + 4(-1) = 3 + 3(1)
2 - 4 = 3 + 3
-2 = 6
We don't end up with the same thing on both sides, so x = -1 is not a solution to the equation.
--------------
Now try x = 0
2x^2 + 4x = 3 + 3x^2
2(0)^2 + 4(0) = 3 + 3(0)^2
2(0) + 4(0) = 3 + 3(0)
0 = 3
That's false as well, which allows us to rule out choice B.
--------------
Next up plug x = 3 into the equation
2x^2 + 4x = 3 + 3x^2
2(3)^2 + 4(3) = 3 + 3(3)^2
2(9) + 4(3) = 3 + 3(9)
18 + 12 = 3 + 27
30 = 30
We get the same thing on both sides so we have confirmed x = 3 is a solution.
--------------
There may be other solutions. If we tried x = 6, then it leads to 96 on the left hand side and 111 on the right hand side. That rules out x = 6 as a solution.
