The weight of water is 62 1/2 lb per cubic foot water that weighs 300 lb will fill how many cubic feet
The number of cubic feet will be 4.8
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given ,
The weight of water is 62 1/2 lb per cubic
Now,
Since, foot water that weighs = 300 lb
Hence, The cubic feet = 300/62.5
= 4.8
Thus, The number of cubic feet will be 4.8

Final answer:
300 pounds of water will fill 4.8 cubic feet of space, calculated by dividing the total weight by the weight per cubic foot (300 lb / 62.5 lb/ft³).
Explanation:
The student is asking how many cubic feet of space would be filled by 300 pounds of water, given that water weighs 62 1/2 pounds per cubic foot. To find the answer, we divide the total weight of the water by the weight of water per cubic foot. In this case, we divide 300 lb by 62.5 lb/ft3 (since 62 1/2 pounds is the same as 62.5 pounds).
The calculation will be as follows:
Divide 300 lb by 62.5 lb/ft3.
300 lb / 62.5 lb/ft3 = 4.8 ft3.
Therefore, 300 pounds of water will fill 4.8 cubic feet of space.

Write a complete two-column proof for following information.
Given: AB = 3y - 1, BC = 7y, AC = 29 Prove: AB = 8
its a normal line and the letters are in order ABC, B is kinda close to A
To prove AB = 8, we substitute the values given and show that the statement is false.
Explanation:To prove: AB = 8
Given: AB = 3y - 1, BC = 7y, AC = 29
Proof:
Since AB = 3y - 1 and AC = 29, we can substitute AC in place of AB in the equation AB = 3y - 1. This gives us 29 = 3y - 1.Simplifying the equation, we get 3y = 30.Dividing both sides of the equation by 3, we find y = 10.Substituting the value of y into AB = 3y - 1, we get AB = 3(10) - 1 = 30 - 1 = 29.Since AB = 29, we can see that AB is not equal to 8. Therefore, the given statement is false.Therefore, we cannot prove that AB = 8.

Solve the equation−3=8x−4y for y
To solve the equation for y, rearrange the terms and isolate the variable y on one side of the equation.
Explanation:To solve the equation -3 = 8x - 4y for y, we need to isolate the variable y on one side of the equation. First, rearrange the terms:
8x - 4y = -3
Now, move the term with x to the right side by subtracting 8x from both sides:
-4y = -3 - 8x
Finally, divide both sides by -4 to solve for y:
y = (3 + 8x) / 4

If sin theta = 12/13 and theta is an acute angle find cot theta
Answer:
cot θ = [tex]\frac{5}{12}[/tex]
Step-by-step explanation:
If sin θ = [tex]\frac{12}{13}[/tex] and 'θ' is an acute angle then we have to find the value of cotθ
From the figure attached.
y² + 12² = 13² [ by Pythagoras Theorem ]
y + 144 = 169
y² = 169 - 144 = 25
y = 5
Now cot θ = [tex]\frac{base}{Height}[/tex]
= [tex]\frac{y}{12}[/tex]
= [tex]\frac{5}{12}[/tex]
Therefore, cot θ =[tex]\frac{5}{12}[/tex] is the answer.
Name the property the equation illustrates. 8 + 5.3 = 5.3 + 8 Inverse Property of Multiplication Inverse Property of Addition Associative Property of Addition Commutative Property of Addition
Answer:
The answer is : Commutative Property of Addition
Step-by-step explanation:
The communicative property of addition shows that "a + b = b + a".
The numbers can be written in any order, the result will be same.
The given terms are : 8 + 5.3 = 5.3 + 8
The solution for both are same; 13.3 = 13.3
So, this shows the commutative property of addition.

In this ordered pair (4,-5) which number is the ordinate
In the ordered pair (4, -5), the number -5 is the ordinate, which represents the vertical position of a point in a coordinate system.
In the ordered pair (4,-5), the number -5 is the ordinate. In a coordinate system, ordered pairs are used to define locations with two values: the x-coordinate and the y-coordinate. The first number in the pair represents the x-coordinate, which is the horizontal position, and the second number represents the y-coordinate, which is the vertical position, also known as the ordinate.
In this context, the ordinate is the position relative to the horizontal axis in a two-dimensional space. It indicates how far up or down a point lies from the horizontal (x) axis. Hence, in the ordered pair (4, -5), -5 is the ordinate. If a point is above the x-axis, its ordinate is positive; if it's below, as in this case, it's negative.

A fighter plane, f, is told to intercept plane x which is 200 miles in front of f flying directly away from f at 500 mph. plane f is told it must intercept x in 6 minutes. how fast should f fly?
To intercept plane x, which is 200 miles in front and flying away at 500 mph, in 6 minutes, the fighter plane f should fly at 2500 mph.
Explanation:The question deals with the calculation of how fast the fighter plane (plane f) should fly in order to intercept plane x in the given time. This is essentially a problem in the physics concept of relative motion. Plane x is 200 miles away from f and is flying away at a speed of 500 mph. The fighter plane f has 6 minutes (or 0.1 hours) to intercept, which is the time needed to cover the distance between the planes. Recall the formula of velocity, v = d/t. Here, the distance d = 200 miles (distance between the planes), and t = 0.1 hours. Substituting these into the formula, we can calculate the necessary speed for plane f.
Additionally, since plane x is moving away from f at 500 mph, plane f must cover an additional 50 miles (500 mph * 0.1 hours) to intercept x. Therefore, the total distance f must cover is 250 miles (200 miles + 50 miles).
Substituting this into the formula of velocity, we find that f should fly at 2500 mph (250 miles / 0.1 hours) to intercept plane x in the allotted time.

The fighter plane 'f' needs to fly at a speed of 2500 mph to intercept the escaping plane 'x' that is flying away at a speed of 500 mph and is currently 200 miles away.
Explanation:To solve this problem, we need to work with the concept of relative speed in the context of motion. Plane 'x' travels 500 miles per hour and the fighter plane 'f' needs to intercept Plane x in 6 minutes, which is 1/10th of an hour.
Since Plane x is 200 miles away, in the 1/10th of an hour, Plane x would have travelled an extra 50 miles (500 mph * 1/10), making the total distance Plane f needs to cover 250 miles (200 miles + 50 miles). To cover 250 miles in 1/10th of an hour or 6 minutes, Plane f needs to fly at a speed of 2500 mph (250 miles / 1/10 hr).
