Answer: circle

Step-by-step explanation:

The shape of the cross-section is formed when a cylinder intersects the plane is a circle option (A) is correct.

In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.

We know the volume of the cylinder is given by:

[tex]\rm V = \pi r^2 h[/tex]

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

As we know, the circle is a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

As we can see in the picture the cylinder is cut by a plane that is parallel to the base of the cylinder.

The base of the cylinder is a circle.

the shape of the cross-section is formed when a cylinder intersects a

the plane is a circle.

Thus, the shape of the cross-section is formed when a cylinder intersects the plane is a circle option (A) is correct.

Answer:

  (x, y) = (4, 5)

Step-by-step explanation:

We notice that the coefficients of y are opposites, so we can eliminate y by adding the two equations together.

  (4x -3y) +(x +3y) = (1) +(19)

  5x = 20 . . . . . . simplify

  x = 4 . . . . . . . . .divide by 5

Substituting into the second equation gives ...

  4 +3y = 19

  3y = 15 . . . . . . . subtract 4

  y = 5 . . . . . . . . . divide by 3

The solution is (x, y) = (4, 5).

Answer:

x=28

y=28

Step-by-step explanation:

Equation 1:

Dived both sides by 0.75 to remove 3/4 from x.

(x-12)=16

Now, add 12 to both sides.

x=28

Equation 2:

Same here, divide both sides by 0.75.

y-12=16

Add 12 to both sides.

y=28

Answer:

y = 15

Step-by-step explanation:

Given :

3, 2, y, 10

If the numbers are in proportion :

We can thus say :

3/2 = y/10

Cross multiply

3 * 10 = 2 * y

30 = 2y

Divide both sides by 2

30 / 2 = 2y / 2

15 = y

Answer: 2/3

Step-by-step explanation:

The probability that the next chew Damian removes from the bag will be cherry or peach as a fraction in simplest form is 55/576

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability for the strawberry chews:

P(strawberry chews) = 16/48

Probability for the cherry chews:

P(cherry chews) = 10/48

Probability for the peach chews:

P(peach chews) = 22/48

Now the probability of cherry or peach = P(cherry)×P(peach)

[tex]=\frac{10}{48} \times\frac{22}{48}[/tex]

= 220/2304

= 55/576

Thus, the probability that the next chew Damian removes from the bag will be cherry or peach as a fraction in simplest form is 55/576

Answer:

D

Step-by-step explanation:

By looking at the terms, we can notice that each term is 4 times the previous term. This means the series is geometric and we can rule out options A and B because of this. We can find the first terms of both options C and D to get:

first term c: 4

first term d: 1

The first term of our series is one, so that must mean D is the answer.
