HELP PLS….Volume of cones
Find the volume of the cone.
Either enter an exact answer in terms of π or use 3.14 for and round your final answer to the nearest hundredth.

Answer:

B

Step-by-step explanation:

if we consider the coordinates of the points

(2, 3 )

(5, 6 )

(7, 8 )

we can see that the y - coordinate in each case is 1 more than the x- coordinate, then

y = x + 1 is the required rule

Answer:

A

Step-by-step explanation:

the domain are the value on the x coordinate

i.e 3, 6, -1, 5, -4 = {-4,-1,3,5,6}

Answer:

A≈78.54

Step-by-step explanation:

A¹=7.7×6.6=50.82(area of rectangle inside)

16.1-7.7=8.4/2=4.2

A²=6.6×4.2=27.72(area of triangles)

A=50.82+27.72=78.54

[tex]sin60 = \frac{opp}{hyp} \\ sin60 = \frac{y}{12 } \\ \frac{ \sqrt{3} }{2} = \frac{y}{12} \\ 2y= 12 \sqrt{3} \\ y = 6 \sqrt{3} [/tex]

[tex]cos60 = \frac{adj}{hyp} \\ cos60 = \frac{x}{12} \\ \frac{1}{2} = \frac{x}{12 } \\ 2x = 12 \\ x = 6[/tex]

The method which is best for solving the system of equations when you remove one variable by adding them is B Elimination

To answer the question, we need to know what system of equations are

System of equations are pairs of equations that contain two unknowns

We have different ways of solving systems of equations which include

Since we have the system of equations

3x + 2y = 4

-3x + y = 2

The method which we can use to remove one variable by adding them is the elimination method.

Adding them, we have

3x + 2y = 4

+

-3x + y = 2

3y = 6

y = 6/3

y = 2

Answer:

x > 8

Step-by-step explanation:

14 - 2(x + 1) < - 4 ← distribute parenthesis and simplify left side

14 - 2x - 2 < - 4

12 - 2x < - 4 ( subtract 12 from both sides )

- 2x < - 16

divide both sides by - 2 , reversing the symbol as a result of dividing by a negative quantity.

The probability that you will have missed your friend is 27.78%

The time of meeting is given as:

Time = 90 minutes (i.e 12pm and 1:30pm)

Your time of arrival is given as:

Arrival = 12:25pm

If you missed your friend, it means that your friend arrives earlier.

So, the time spent by your friend is:

Friend= 12:25 - 12 = 25 minutes

The probability that you will have missed your friend is:

P = 25 minutes/90 minutes

Evaluate

P = 27.78%

Hence, the probability that you will have missed your friend is 27.78%

The inequality which is used to find the number of minutes taken by the solution to begin caramelising is 310 < 250 + 5x <338. The correct answer is option A.

The complete question is given below:-

A sugar solution currently measures 250 degrees Fahrenheit. The temperature of the solution increases 5 degrees per minute. The sugar solution will caramelize at temperatures greater than 310 and less than 338 degrees Fahrenheit. Which inequality can be used to find x, the number of minutes it will take for the solution to begin caramelizing? 310 < 250 + 5x < 338 310 < 250 + 5x < 338 310 < 5(x + 250) < 338 310 < 5(x + 250) < 338

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions is called an inequality.

According to the given question.

The current temperature of a sugar solution is 250 degrees Fahrenheit. Per minute the temperature of the solution increases by 5 degrees. Also, x is the number of minutes taken by the sugar to caramelize.

⇒ The total increase in the temperature in x minutes = 25 + 5x

Since the sugar solution caramelizes at a temperature greater than 310 and less than 338.

Inequality will be given as:-

310 < 250 + 5x < 338

Therefore, the inequality which is used to find the number of minutes taken by the solution to begin to caramelize is given by 310 < 250 + 5x < 338.

The set of parallel lines in a quadrilateral leads to the parallelogram.

Any closed figure made by 4 line segments joined end to end in series is called a quadrilateral.

Line M

x - y + 3 = 0,

y = x + 3

m = 1

Line L

y = x - 2,

m = 1

Line N

y = -1/2x + 5,

m = -0.5

Line P

x+2y+12=0

y = -x/2 - 6

m = -0.5

Here we can see that the slope of line M and L are equal and slope of line N and P are equal.

That quadrilateral in which opposite sides are parallel is called a parallelogram.

Answer: 2

Step-by-step explanation:

DE * CE = AE * BE (Two Secants Segment Theorem)

▪︎ DE = 1 + x + 4

▪︎ CE = x + 4

▪︎ AE = 11 + x + 1

▪︎ BE = x + 1

=> (1 + x + 4)(x + 4) = (11 + x + 1)(x + 1)

=> (x + 5)(x+4) = (x + 12)(x + 1)

=> x^2 + 9x + 20 = x^2 + 13x + 12

=> 9x + 20 = 13x + 12

20 - 12 = 13x - 9x

8 = 4x

x = 2

Volume is a three-dimensional scalar quantity. The volume of the right-triangular pyramid is 1.008 m³.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of a right-triangle pyramid is one-third of the product of its base area and its height. Therefore, the volume is,

Volume = (1/3) × 0.5 × 1.4 × 1.8 × 2.4

             = 1.008 m³

Hence, the volume of the right-triangular pyramid is 1.008 m³.
