2 1/2 hours is 150 minutes and your covers 150 miles in 150 minutes, so remove 30 minutes because 1/2 an hour is 30 minutes and remove 30 miles because you're going of time because 1 minute = 1 mile

if it takes 3/4 of an hour to fill 3/5 of a pool how many hours will it take to fill the pool completely

Answers

The time taken to completely fill the pool is 5/4 hour

How to determine the time to fill the pool?

From the question, the given parameters are:

Time =3/4 hour

Size of the pool = 3/5

The time to fill the pool is then calculated as

Time = Given time/Proportion of the pool

Substitute the known values in the above equation

So, we have the following equation

Time = 3/4 hour ÷ 3/5

Express the quotient as product

So, we have the following equation

Time = 3/4 hour x 5/3

Evaluate the products

Time = 5/4 hour

Hence, the time taken is 5/4 hour

Write the equation of the line in the slope-intercept form which is parallel to
y = −2x +5 and passing through the point (1, −4)

Answers

The equation of the line that is parallel to the line y = −2x +5 and passing through the point (1, −4) is y = -2x - 2.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

The slope of two parallel lines is always the same.

The slope y-intercept form of an equation is y = mx + c where m is the slope.

Given the parallel equation y = -2x + 5 by compare slope = -2

Therefore,the equation will become y = -2x + c

Substitute,(1,-4) into this

-4 = -2(1) + c ⇒ c = -2

So equation converts as y = -2x - 2.

Hence "The equation of the line that is parallel to the line y = −2x +5 and passing through the point (1, −4) is y = -2x - 2".

p(x) = x^3 − 3x^2 − 10x + 24 , has a known factor of (x-4).
rewrite p(x) as the product of linear factors

Answers

The product of linear factors for p(x) is given as (x-4)(x^2+x-6).

What is the factor theorem?

The factor theorem states that;

p(x) is divisible by x-a if and only if p(a)=0p(x) is divisible by x+a if and only if p(-a)=0

From the question, given that x-4 is a factor of

p(x) = x^3 − 3x^2 − 10x + 24,

then it is divisible by x-4 and p(4)=0.

Dividing x^3 − 3x^2 − 10x + 24 by x-4 using the long division will result to another factor x^2+x-6 with a remainder of zero.

We can then conclude that (x-4)(x^2+x-6) is the product of linear factors for p(x).

Went to start the sum of -1 3/4 and 2 1/2 is the same as the difference between 2 1/2 and 1 3/4 is Gwen correct explain why or why not

Answers

The sum of  -1 (3/4) and 2 (1/2) is the same as the difference between 2 (1/2) and 1 (3/4).

Firstly, we will convert the mixed fractions into improper fractions.

-1 and 3/4 = -7/4

2 and 1/2 = 5/2

Addition of -1 (3/4) and 2 (1/2) = -7/4 + 5/2 = -7/4 + 10/4 = 3/4

Difference between  2 and 1/2 and 1 and 3/4 = 5/2 - 7/4 = 10/4 - 7/4 = 3/4

As both the values equal to 3/4 , we can say that the addition of  -1  and 3/4 and 2 and 1/2 is the same as the difference between 2 and 1/2 and 1 and 3/4.

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.

Does anyone know how to write a linear equation to find the length and width of a perimeter? Ex...
Write a linear equation to represent the given problem and then solve the problem.

The perimeter of a rectangle is 150 cm. The length is 15 cm greater than the width. Find the dimensions.

Answers

The linear equation that represents the problem is  4w + 30 = 150.

The dimension(width and length) of the rectangle is 30 cm and 45 cm .

How to find the dimensions of a rectangle?

A rectangle is a quadrilateral with 4 sides.

Opposite sides of a rectangle are equal to each other.

Opposite sides of a rectangle are parallel to each other.

Therefore,

perimeter of a rectangle = 2(l + w)

where

l = lengthw = width

Hence, the perimeter of the rectangle is 150 cm. The length is 15cm greater than the width.

Therefore,

perimeter of rectangle = 150 cm

l = 15 + w

Hence,

150 = 2(15 + w + w)

150 = 2(15 + 2w)

150 = 30 + 4w

Therefore, the linear equation to represent the problem is  4w + 30 = 150.

Let's solve for the dimension of the rectangle.

4w + 30 = 150.

4w = 150 - 30

4w = 120

w = 120 / 4

w = 30 cm

L = 15 + 30 = 45 cm

Therefore,

length = 45 cm

width = 30 cm

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.

3x ➡️ 3(35) = 105
2x ➡️ 2(35) = 70
4x ➡️ 4(35) = 140
10 degrees is already known

Step by step

The angles are x and 3x and 2x and 4x and 10 degrees, they form a complete circle equal to 360 degrees. So our equation to solve

x + 3x + 2x + 4x + 10 = 360

Combine like terms

10x + 10 = 360

Subtract 10 from both sides to isolate x

10x +10 -10 = 360 -10

Combine like terms

10x = 350

Divide by 10 to solve for x

x = 35

Now we use the expressions for each angle and substitute value of x (35) for x

x ➡️ = 35
3x ➡️ 3(35) = 105
2x ➡️ 2(35) = 70
4x ➡️ 4(35) = 140
