The volume of this cylinder is 1751 cubic units. What is the volume of a cone that has the same base area and the sam height

Answers

Answer:

[tex]V_2 = 583.67[/tex]

Step-by-step explanation:

Given

Represent the volume of the cylinder with V1 and the cone with V2.

So:

[tex]V_1 = 1751[/tex]

Required

Find V2

The volume of a cylinder is:

[tex]V_1 = \pi r^2h[/tex]

Because the cone and the cylinder have the same base area and height, the volume of the cone is:

[tex]V_2 = \frac{1}{3}\pi r^2h[/tex]

Substitute [tex]V_1[/tex] for [tex]\pi r^2h[/tex].

[tex]V_2 = \frac{1}{3}\pi r^2h[/tex]

[tex]V_2 = \frac{1}{3}V_1[/tex]

Substitute 1751 for V1

[tex]V_2 = \frac{1}{3} * 1751[/tex]

[tex]V_2 = \frac{1* 1751}{3}[/tex]

[tex]V_2 = \frac{1751}{3}[/tex]

[tex]V_2 = 583.67[/tex]

The volume of the cone is 583.67 cubic units

DON AND 3 FRIENDS SHARE 2 sandwiches at lunch which equation can be used to find out how much sandwich each person gets at the sandwich are shared equally
A. X= 4÷2
B. X= 2 ÷4
C. X= 1÷3
D. X= 1÷4​

Answers

Answer: B. x = 2/4

Reason:

The thing they need to share are the sandwiches (y), where x is the amount of sandwich per person, so that goes in the equation first.

4/2 is 2 so that doesn’t make sense.

C isn’t an option because there are 4 people in this word problem. Don and his 3 friends = 4.

D isn’t right because there’re 2 sandwiches, not 1.

A directed line segment starts at (1.0) and ends at (4.6), Point R partitions the segment
in the ratio of 2 to 1. What are the coordinates of point R?
(PLEASE HELP ASAP)

Answers

9514 1404 393

Answer:

  (3.4)

Step-by-step explanation:

The length of the given segment is 4.6 -1.0 = 3.6. The first portion of the division will be 2/(2+1) = 2/3 of that length, or (2/3)(3.6) = 2.4.

Then the coordinates of point R are ...

  (1.0) +(2.4) = (3.4)

__

Additional comment

We cannot tell if your coordinates are supposed to be Cartesian coordinates (1, 0) and (4, 6), or if they are points on a number line. As it happens, it makes no difference. The final answer is interpreted the same way the given coordinate points are interpreted: 3.4 on a number line or (3, 4) on a plane.

Answers

Answer:

4. The expression has a value of 1/36 . True

5. An equivalent expression is (6)^5. (6)^- 7  True

Step-by-step explanation: Not true. The 6 without an exponent is equivalent to the 6 having a 0 exponent.

Any number having an exponent zero has a value equal to 1.

6 · (6)^0 · (6)^–3

= 6.1.1/216

= 1/36

= (6)^-2

2. The sum of exponents is 2.  

False ( the sum of exponents is -2)

3.Multiply the exponents to solve the expression .

False when the bases are the same the exponents are added or subtracted.

4. The expression has a value of 1/36 .

The correct answers are, length is 21 inches, and the width is 10 inches.


L=length; W=width.

L-2W=1
L=2W+1

P=2(L+W)
62in=2((2W+1)+W)
31in=3W+1
30in=3W
10in=W
The width is 10 inches.

L=2W+1=2(10in)+1=20in+1in=21in
The length is 21 inches.

Answer:

The correct answer is A:Let n = k. Then assume that 11" - 6 is divisible by 5. sorry if im wrong but if correct pls mark brainliest

Answer:

Step-by-step explanation:

Premise:  If n is a positive integer, then 11ⁿ-6 is divisible by 5.

Let n=1.

11¹-6 = 5, so the premise is true for n=1.

Suppose the premise is true when n is an integer greater than 1,

then 11ⁿ-6 is divisible by 5.

11ⁿ⁺¹-6 = 11·11ⁿ - 6

   = (10+1)11ⁿ - 6

   = (10·11ⁿ) + (1·11ⁿ) - 6

   = (10·11ⁿ) + (11ⁿ - 6)

Both terms are divisible by 5, so 11ⁿ⁺¹-6 is divisible by 5. Therefore, the premise holds true for n+1.

Proof by induction.

Answer:

x = -9 1/2

y = -16 1/2

Step-by-step explanation:

x - y = 7

solve the above for 'y':  -y = 7 - x

multiple each side by -1:  y = x - 7

now both equations are in 'y=' form

x - 7 = 3x + 12

-2x - 7 = 12

-2x = 19

x = -19/2 or -9 1/2

-9.5 - y = 7

-y = 16.5

y = -16.5 or -16 1/2
