jon's bathtub is rectangular and its base is 18 ft2. how fast is the water level rising if jon is filling the tub at a rate of 0.6 ft3/min? (use decimal notation. give your answer to three decimal places.)
Answers
Jon's bathtub exists rectangular and its base exists 18 ft². The water level rising if Jon is filling the tub at a rate of 0.2 ft³/min is 0.011 ft/min.
What is meant by differential equation?A differential equation in mathematics exists an equation that links the derivatives of one or more unknown functions. Applications often involve functions that reflect physical quantities, derivatives that depict the rates at which those values change, and a differential equation that establishes a connection between the three.
If we take a look at a rectangular bathtub, the volume of the bathtub can be expressed as:
Volume (V) = length × breadth × height
where; base = length × breadth = 18ft²
The volume of the rectangular bathtub = 18h ......... (1)
Using differentiation to differentiate 18h with respect to t implicitly, then:
[tex]$\frac{\mathrm{dV}}{\mathrm{dt}}=18 \frac{\mathrm{dh}}{\mathrm{dt}}$$[/tex]
When the rate of rising of the volume is 0.2 ft² / min
[tex]$0.2=18 \frac{\mathrm{dh}}{\mathrm{dt}}$$[/tex]
substitute the values in the above equation, we get
[tex]$\frac{\mathrm{dh}}{\mathrm{dt}}=\frac{1}{18} \times(0.2)$$[/tex]
[tex]$\frac{\mathrm{dh}}{\mathrm{dt}}=0.011 \mathrm{ft} / \mathrm{min}$$[/tex]
Therefore, we can conclude that the rate at which the water level rises if Jon is filling the tub at 0.2 ft³/min exists 0.011 ft/ min.

The function has an equation of f(x) = (x + 4)(x - 2)
How to determine the equation of f(x)?The given parameters in the question are
Roots = -4 and 2
Point = (1, -5)
The above parameters can be rewritten as
Roots: x = -4 and x = 2
Point: (x, y) = (1, -5)
A quadratic equation can be represented as
f(x) = a * (x - Roots)

working together, it takes two different sized hoses minutes to fill a small swimming pool. if it takes minutes for the larger hose to fill the swimming pool by itself, how long will it take the smaller hose to fill the pool on its own?
Answers
Time taken by the smaller hose to fill the pool on its own = 75 minutes
Time taken to fill the swimming pool by the larger hose and smaller hose working together = 30 minutes
Time taken by the larger hose to fill up the swimming pool = 50 minutes
Let 'x' be the time taken by the smaller hose to fill the swimming pool on its own.
In 30 minutes, the larger and smaller hoses together can fill the swimming pool. So in 1 minute, it can fill up 1/30 of the swimming pool.
In 50 minutes, the larger hose can fill up the swimming pool on its own. So the larger hose can fill up 1/50 of the pool in 1 minute.
It takes 'x' minutes for the smaller hose to fill up the pool on its own. So in 1 minute, the smaller hose alone can fill up 1/x of the pool.
Hence 1/30 = 1/x +1/50
⇒ 1/30 = (50+x)/50x
⇒ 30 = 50x/(50+x)
⇒ 30 (50 + x) = 50x
⇒ 1500 + 30x = 50x
⇒ 20x = 1500
⇒ x = 1500/20
⇒ x = 75 minutes.
Thus the smaller hose alone takes 75 minutes to fill up the pool.
The question is incomplete. Find the complete question below:
Working together, it takes two different sized hoses 30 minutes to fill a small swimming pool. If it takes 50 minutes for the larger hose to fill the swimming pool by itself, how long will it take the smaller hose to fill the pool on its own?

- We have boxes only able to hold 10
What we need to figure out:
- how many boxes at the least are we going to need
Step 1: Divide
Since we need to figure out how many times 10 goes into 127 we divide 127 by 10 so...
127/10 = 12 with a remainder of 7.
Step 2: Figure out the remainder
Since there are seven left over and you cannot put them in boxes already being used then we put them in a new box, not yet used. That would make it a total of 13 boxes needed at the least.

Consider the line y = = 8 x-4. Find the equation of the line that is parallel to this line and passes through the point (7, -2). Find the equation of the line that is perpendicular to this line and passes through the point (7, -2).
Answers
Answer: y=8x-58
Step-by-step explanation:
1. find the slope
Since the new line is parallel to the first one that means the slope of 8x will remain the same.
2. plug it into the point slope formula y-y1=m(x-x1)
which would look like
y-(-2)=8(x-7)
3. solve for y
y-(-2)=8(x-7)
y+2=8x-56
y=8x-58
Parallel slope = 8
Perpendicular slope = -1/8
Use point slope. Use point and respective slope.
y-y1= m(x-x1)
y+2 = 8(x-7)
y+2 = 8x - 56
y= 8x - 58 (parallel equation)
y-y1= m(x-x1)
y+2 = -1/8(x-7)
y+2 = -1/8x +7/8
y= -1/8x - 11/8 (perpendicular equation)

Answer:
ASA
Step-by-step explanation:
ASA stands for Angle-Side-Angle which is the congruency theorem that states that if a triangle shares two congruent angles that have one line in between the two angles share a side length congruent to each other, then the two triangles are congruent.
Before you get very confused on the difference between AAS (Angle-Angle-Side) and ASA (Angle-Side-Angle), let explain why these two triangles are ASA.
We are given that both triangles share a similar side length at KL where they are connected. We are also given that angle ∠JKL is congruent to angle ∠MKL. We are also given that angle ∠MLK is congruent to angle ∠JLK.
The most important part after deciding all the relationships is given to us, it is deciding what kind of congruence theorem we will use. We are given the options:
SSS (Side-Side-Side) SAS (Side-Angle-Side) ASA (Angle-Side-Angle) AAS (Angle-Angle-Side) HL (Hypotenuse-Leg)Because we are presented with two congruent angles and one congruent side, we know that this triangle congruency theorem is either ASA or AAS. To understand why these triangles are ASA, we have to look at where the two-given congruent sides are located. As we can see in the name and in our two triangles, the congruent side lengths are in between the two angles as it touches both angle ∠JKL and angle ∠JLK in triangle ΔJKL, while in on ΔMKL, the congruent side length is also found between angle ∠MLK and angle ∠MKL. So, these triangles share ASA because they share two congruent angles connected by one congruent line.
ORDER MATTERS WHEN YOU WRITE YOUR CONGRUENCY THEROMS
AAS is technically not the same as ASA and I will explain that in one moment.
An example of AAS is if instead being told that ∠JKL is congruent to angle ∠MKL, we are given that ∠KJL is congruent to angle ∠KML instead. now the congruent sides are not connected to angle ∠KJL or angle ∠KML. The side is no longer in-between the two congruent sides. The reason order matters here are because order matters between AAS and ASA because in another theorem, SAS, you will find out order matter because while SAS guaranties congruency SSA does not. Technically, though, while both AAS and ASA both guaranty congruency, they are labeled separately, the way the remaining congruency thermos are.
a company that manufactures mufflers for cars offers a lifetime warranty on its products, provided that ownership of the car does not change. suppose that only 20% of its mufflers are replaced under this warranty. a button hyperlink to the salt program that reads: use salt. (a) in a random sample of 400 purchases, what is the approximate probability that between 70 and 90 (inclusive) mufflers are replaced under warranty? (round your answer to four decimal places.)
Answers
The approximate probability that between 70 and 90 is 0.728.
Using normal distribution,
Mean = xbar = np = 400 × 0.2 = 80
Standard deviation = √[np(1-p)] = √(80 × 0.8) = 8
To ensure that the distribution is normal,
np ≥ 10
80 ≥ 10
And,
np(1-p) ≥ 10
80(0.8) = 320 ≥ 10
Hence, we use the z-tables for this
a) Convert 75 and 100 into standardized scores.
A value's standardized score is equal to the value minus the mean divided by the standard deviation.
z = (x - xbar) ÷ σ
For 75
z = (75 - 80) ÷ 8 = - 0.625
For 100
z = (100 - 80) ÷ 8 = 2.5
To calculate the approximate likelihood that between 75 and 100 (inclusive) mufflers will be replaced under warranty.
P(75 ≤ x ≤ 100) = P(-0.625 ≤ z ≤ 2.5)
For these probabilities, use data from the normal probability table.
P(75 ≤ x ≤ 100)
= P(-0.625 ≤ z ≤ 2.5)
= P(z ≤ 2.5) - P(z ≤ -0.625)
= 0.994 - 0.266

Answers
The measure of ∠C is 121 degrees.
Given that:-
There is a triangle ABC.
m∠A = (x + 6)°
m∠B = (3x - 15)°
m∠C = (5x + 36)°
We have to find the measure of ∠C.
We know that,
The sum of all the angles of a triangle is 180 degrees.
Hence, we can write,
m∠A + m∠B + m∠C = 180 degrees
(x + 6)° + (3x - 15)° + (5x + 36)° = 180 degrees
(x + 3x + 5x) + (6 - 15 + 36) = 180 degrees
9x + 27 = 180 degrees
9x = 180 - 27
9x = 153 degrees
x = 153/9 degrees
x = 17 degrees
Hence,
The measure of ∠C = 5x + 36 = 5*17 + 36 = 85 + 36 = 121 degrees.

A Ford F-150 truck is considered a half-ton truck because that is how much it can haul. How many pounds can the truck haul?
Answers
The truck can haul 1102 pounds.
According to the question,
We have the following information:
A Ford F-150 truck is considered a half-ton truck because that is how much it can haul.
(We will not directly convert ton into pounds. We will follow the following steps.)
Now, we know that 1 ton is equal to 1000 kilograms.
So, half ton makes 500 kg.
Now, to convert this into pounds, we will multiply 500 kg by 2.205 because we know that 1 kg is equal to 2.205 pounds.
1 kg = 2.205 pounds
500 kg = (500*2.205) pounds
500 kg = 1102.5 pounds

Degree is the unit of measure is used to measure the magnitude of an angle.
1 degree = 1/360 of a complete revolution in magnitude.
Given,
Here we have the following expressions
(7x-2)°
18y°
(11x - 34)°
Now, we have to find the value of x and y from it.
In order to find the value x and y , we have to equate every equation with 0. then we get the value of variables x and y.
When we take the first expression, and then we have to equate it with zero, then we get,
(7x - 2)° = 0°
7x = 2°
x = 2/7°
Therefore, the value of x is 2/7°.
Now, we have to take the second one and equate it with zero, then we get,
18y° = 0
y = 0°
Therefore, the value of y is 0°.
Finally, the value of the expression in degrees,
11x - 34° = 0

In this figure, m∠2=(6x+20)∘ and m∠8=(8x−10)∘ .
What value of x makes a∥b ?
Enter your answer in the box.
Answers
If the ∠2 = 6x+20 degrees and ∠8 = 8x-10 degrees, then the values of x is 15
The lines a and b are parallel lines
Here two parallel lines a and b are cut by a transversal t
The angles are
∠2 = 6x+20 degrees
∠8 = 8x-10 degrees
The angle 2 and angle 8 are called alternate exterior angles
When the two parallel lines are cut by a transversal, the formed alternate exterior angles are equal.
Then
6x+20 = 8x-10
Solve the equation
6x-8x = -10-20
-2x = -30
x = -30/-2
x = 15
Hence, if the ∠2 = 6x+20 degrees and ∠8 = 8x-10 degrees, then the values of x is 15.
