I need help please. volume of rectangular prisms

Answer:

20

Step-by-step explanation:

Since we are told that line a is parallel to line b, even if it's not visible in the image, we can say that ∠5 = ∠1, since they are formed by the same line crossing parallel lines.

So, we have

∠4 = 3x

∠5 = ∠1 = 6x

Since ∠4 and ∠5 are complementary angles formed by line t, we know their sum is 180 degrees. So,

∠4 + ∠5 = 180

3x + 6x = 180

9x = 180

x = 20

Answer is 20.

Answer:

The perimeter of the triangle ABC is 22.8 units

Step-by-step explanation:

* Lets study the information in the problem

- There is Δ ABC with vertices:

  A (-2 , 2) , B (6 , 2) , C (0 , 8)

- The perimeter of the triangle is the sum of the length of its

  three sides

* We must to find the lengths of AB , BC and CD

- The rule to find the distance between 2 points (x1 , y1) and (x2 , y2) is

  √[(x2 - x1)² + (y2 - y1)²]

* Lets find the lengths of the three sides

- Length of AB

∵ A = (-2 , 2) and B = (6 , 2)

∴ AB = √[(6 - -2)² + (2 - 2)²] = √8² = 8 units

- Length of BC

∵ B = (6 , 2) and C = (0 , 8)

∴ BC = √[(0 - 6)² + (8 - 2)²] = √[6² + 6²] = √72 = 6√2 units

- Length of AC

∵ A = (-2 , 2) and C = (0 , 8)

∴ AC = √[(0 - -2)² + (8 - 2)²] = √[2² + 6²] = √40 = 2√10 units

* Now lets find the perimeter of the triangle

∵ The perimeter = AB + BD + AC

∴ The perimeter = 8 + 6√2 + 2√10 = 22.8 units

* The perimeter of the triangle ABC is 22.8 units

Answer:

The perimeter of triangle ABC = 22.78 units

Step-by-step explanation:

Formula:-

The length of line segment with end points (x₁, y₁) and (x₂, y₂) is given by,

Length = √ [(x₂ - x₁)² + (y₂ - y₁)²]

To find the each side of triangle

We have  A(-2,2), B(6,2), and C(0,8).

AB =  √[(6 - -2)² + (2 - 2)²] =  √64 = 8

BC = √[(0 - 6)² + (8 - 2)²] = √(36 + 36) = 8.48

AC = √[(0 - -2)² + (8 - 2)²] = √(4 + 36) = 6.3

To find the perimeter of triangle ABC

Perimeter = AB + BC + AC

 = 8 + 8.48 + 6.3 = 22.78 units

Final answer:

Jefferson played basketball until 2:57 P.M.

Explanation:

To find out what time Jefferson played basketball until, we need to add the duration of time he played to the starting time.

First, we convert the duration of time from minutes to hours. Since there are 60 minutes in an hour, 1 hour and 25 minutes is equal to 1.42 hours.

Next, we add 1.42 hours to the starting time of 1:15 P.M. This gives us the ending time of 2:57 P.M.

Answer:

x=30

Step-by-step explanation:

Answer:

x = 61.3°

Step-by-step explanation:

We are given the radius r = 9 cm and arc length l = 9.7 cm. We need to find the angle x in degrees.

The formula used is:

l = rФ

In our case Ф = x. So re writing the formula:

l= rx

9.7 = 9 x

=> x = 9.7 / 9

x = 1.07 radians

Converting radians into degree we need to multiply the value of x by

180/π where π = 3.14

x = 1.07 * 180/3.14

x = 61.3°

Answer:

The equation that can be used to find d is [tex]2d+17=41[/tex]

[tex]d=12\ dogs[/tex]

Step-by-step explanation:

Let

d -----> the number of dogs

we know that

The linear equation that represent this situation is

[tex]2d+17=41[/tex]

Solve for d

Subtract 17 both sides

[tex]2d=41-17[/tex]

[tex]2d=24[/tex]

Divide by 2 both sides

[tex]d=12\ dogs[/tex]

Final answer:

The equation to find the number of dogs at the shelter is 2d + 17 = 41, where 2d represents the total cups of food eaten by the dogs and 17 represents the cups eaten by the cats per day.

Explanation:

To find d, the number of dogs at the animal shelter, we can use the information provided to set up an equation. We know the shelter uses 41 cups of food each day in total, and that cats eat 17 cups in total per day. Since each dog eats 2 cups per day, we can represent the number of cups dogs eat as 2d, where d is the number of dogs. We can then express the total food used as the sum of the food eaten by the cats and the food eaten by the dogs, which gives us the equation:

2d + 17 = 41

This equation can be used to find the number of dogs at the shelter since solving for d would give us the total number of dogs based on their food consumption.

I am definitely willing to assist you, but without an illustration is a tough challenge.

Answer:

option A.

Step-by-step explanation:

We know that the volume of a rectangular prism is the product of its base area and height. That is to say:

Volume = Base Area x Height

Where: x^3-3x^2 +5x-3

Height: x^2-2

Volume =

Solving for "Height" we have:

Height = Volume / Base Area

Height = (x^3-3x^2 +5x-3) / (x^2-2)

Using ruffinis law we have that the solution is:

x-3 with a remainder of 7x-9

That is to say:

x-3 + (7x-9)/(x^2 - 2)

That is option A.

Answer: C

Step-by-step explanation:

25,230 x .15= 3,784.50

25,230- 3,784.50= 21,535

21,535/36= 598.20833

598.20833 x 1.0671= 638.348109

638.348109 x 36= 22,980.5319

Answer:

Letter C $23,735.84.The result varies a few dollars, because during the solution an adjustment was made to the decimals.

Step-by-step explanation:

1. Define the price of the vehicle you are going to buy with the dealer or seller

Principal: $25230

Rate= 6.71%

N= 36 months

Down payment=15% of the cost of the vehicle= (25230*0.15)=$3784.50

25230-3784.50=21445.5

2. Apply the amortization formula to determine the monthly payments. With this taxation, you will determine the payments applied to the principal and the copper of interest.

A=P*(r(1+r)^{n})/((1+r)^{n}-1).

A= amortization or monthly payments.

P=Principal

R=interest rate

N= the total number of months

a. Calculate the monthly interest rate. The annual interest rate is 6.71% percent. Divide it by 12 to get the monthly interest rate. The monthly interest rate is 0.5592 percent (6.71/12 = 0.5592)  

A=21445.5*(0,005592 (1+0,005592)^{{36}})/(1+0,005592)^{{36}}-1.

A=21445.5*(0,00683/0,2223)

A=21445.5*0,03072=658.90

Total of the payment= 658.90*36=23720.40

Final answer:

Classifying functions involves identifying whether a population is experiencing growth, depicted by exponential or J-curve growth models, or decay, which is often described through logistic or S-curve models. Exponential growth shows unrestricted rapid increases, while logistic growth accounts for environmental limits and a carrying capacity. Age structure diagrams provide further context for the type of population change being observed.

Explanation:

Growth and Decay in Biological Functions

When classifying functions as growth or decay, one must consider the nature of the function in relation to the context of time and population size. For instance, when discussing bacterial growth, Curve A depicting exponential growth is characterized by a population size that increases rapidly over time, often without any constraints. This curve represents a J-curve model on a graph where population size skyrockets as time progresses. On the other hand, Curve B illustrates logistic growth, which follows an S-curve model where the population grows rapidly at first and then slows down as it reaches carrying capacity, a point where growth rate starts to decline.

Different time intervals on a growth curve represent various phases, such as the lag phase, where growth is slow or negligible; the log phase or exponential phase, where the number of cells increases dramatically; the stationary phase, where growth rate is zero due to resource depletion or waste accumulation; and the death phase, where the number of live cells declines.

Various types of growth in organisms can be identified by their structural adaptations or ecological contexts, such as whether they are terrestrial or aquatic, or whether they are deciduous or evergreen plants. Additionally, age structure diagrams for populations can reveal if a population is rapidly growing, growing slowly, stable, or in decline.

The pool has area [tex]160\,\mathrm{ft}^2[/tex].

Let [tex]x[/tex] be the width of the sidewalk. Then the combined area of the pool and sidewalk is [tex](10+x)(16+x)=160+26x+x^2[/tex], so that the area of the sidewalk alone is [tex]26x+x^2[/tex].

We're told this area is [tex]155\,\mathrm{ft}^2[/tex], so

[tex]26x+x^2=155\implies x^2+26x-155=(x-5)(x+31)=0\implies x=5[/tex]

Answer:

The width of the sidewalk is 5.0 ft.

Step-by-step explanation:

Given,

The dimension of the rectangular swimming pool is 16 ft × 10 ft,

So, the area of the pool = 16 × 10 = 160 ft²,

Let x be the uniform width of the cement sidewalk,

So, the dimension of the area covered by both swimming pool and sidewalk = (16+x) ft × (10+x) ft,

Thus, the combined area of the swimming pool and sidewalk = (16+x)(10+x) ft²

Also, the area of the sidewalk = The combined area - Area of the pool,

= (16+x)(10+x) - 160

According to the question,

[tex](16+x)(10+x)-160 = 155[/tex]

[tex](16+x)(10+x)=315[/tex]

[tex]160+16x+10x+x^2=315[/tex]

[tex]x^2+26x-155=0[/tex]

By the quadratic formula,

[tex]x=\frac{-26\pm \sqrt{676+620}}{2}[/tex]

[tex]x=\frac{-26\pm 36}{2}[/tex]

[tex]\implies x=5\text{ or } x = -31[/tex]

Side can not be negative,

Hence, the width of the sidewalk is 5.0 ft.
