. Frosty Snacks sells ice cream in a cylindrical cup and in cones.

The small cup of ice cream has a height of 4 inches and a radius

of 2 inches. The small cone has a height of 6 inches and a

diameter of 5 inches. How much more ice cream will fit into a

small cup than a small cone? Use 3.14 for pi.

Answers

Answer:

10.99 in^3

Step-by-step explanation:

Steps to determining the answer

determine the volume of the cylinderdetermine the volume of the conefind the difference in volumes

volume of a cylinder = nr^2h

n = 3.14

r = radius

3.14 x 4 x 2² = 50.24 in³

Volume of a cone 1/3(nr^2h)

n = 22/7

r = radius

A radius is half of the diameter = 5/2 = 2.5 in

h = height  

(1/3) x 3.14 x 2.5² x 6 = 39.25 in³

difference = 50.24  - 39.25 = 10.99 in³

A straight line L is perpendicular to line 3x-2y+4=0. The area of triangle formed by the line L and coordinate axes is 27 sq.unit find equation of line L​

Answers

First write the equation in the standard form of y=mx+c
3x-2y+4=0
3x+4=2y
( divide by 2)
3/2x+2=y
Now let’s find the perpendicular line to y=3/2x+2
You just have to get the opposite of the slope 3/2 which is -2/3
If you multiply 3/2 by -2/3 you will get -1 this proofs it really is the perpendicular slope your are looking for
Hence
The equation of line L is
y=-2/3+2

A small theater had 6 rows of 23 chairs each. Workers just removed 9 of these chairs. How many chairs are left?

Answers

Answer:

129

Step-by-step explanation:

6 rows of chairs * 23 chairs in each row = 138 total chairs.

If 9 of these chairs were removed, that becomes 138 - 9 = 129.

There are 129 chairs left.

Forgive me if i’m wrong but

6 x 23 = 138
138 -9 =129
Answer: 129 chairs remain

Part A: If Angle A and Angle B are vertical angles, what is value of x
A. 8
B. 10
C. 35
D. 28

Answers

Answer:

A. 8

Step-by-step explanation:

Since ∠A and ∠B are vertical, we can create the equation: 40 = 5x.

40 = 5x

There is only one other thing we need to do, and that's divide by 5.

40/5 = x

x = 8

The value of x in this case is 8, which is A.

What is the volume of this square pyramid?

Answers

Answer:

400m^3

Step-by-step explanation:

Answer: [tex]400m^{2}[/tex]

Step-by-step explanation:

In order to solve this square pyramid's volume, we use the formula:

V = 1/3(B)(h)

Now, we plug in what we know. Since it has a square base, the sides of the base are all the same:

1/3(10*10)(12)

Now we solve:

1/3(100)(12)

1/3(1200)

What does it mean if (3, 2) is a solution of

{

y = x - 1

y = -x + 5

?

Answers

(x,y) = (3,2)

y = x - 1

2 = 3 - 1

2 = 2

y = -x + 5

2 = -3 + 5

2 = 2

If (3, 2) is a solution of the system y = x - 1 and y = - x + 5 then the ordered pair (3, 2) satisfies both equations simultaneously.

What is the graphical solution of a system of equations?

Graphical solutions of a system of equations are way of finding the intersection points of all the equations given.

A system with two or more than two equations has a solution only when they have a common intersection point.

Given, The system of equation y = x - 1 and y = - x + 5 has a

solution (3, 2).

If the ordered pair (3, 2) is a solution of both equations this implies that this ordered pair satisfies both equations simultaneously.

For,

y = x - 1.

At, x = 3,

y = 3 - 1

y = 2   (satisfied).

For,

y = - x + 5.

At, x = 3,
