greta makes a slice through a three-dimensional object parallel to the base the cross section is a circle. What three dimensional shapes might greta have cut?

Answers

Answer 1

Answer:

Answer:

A. Cylinder.

C. Cone.

Step-by-step explanation:

Notice that the cross section is parallel to the base. So, if the cross section is a circle, then the base is also a circle.

Then, we just need to find all figures that have a circle at the bottom. The figures are a cylinder and a cone.

Therefore, the right answers are A and C.

Answer 2

Answer:

Answer:

A. Cylinder

C. Cone

Step-by-step explanation:

Both a cylinder and a cone are three dimensional shapes that contain a circle as the base. If a cross section is made parallel to the base, that means that it should have the same shape as the base. Since a pyramid and cube both have straight edges, it would not be possible to form a circle from a parallel cut to the base, so the only options are cylinder and cone.

Answers

Easy..

let's take a view fractions and decimals and make a little example ourselves...

Let's use: $(1)/(4)$ , 0.75, $(1)/(2)$ , and 1

Keep it simple...

So, now let's plot those on a number line...it's fairly easy...

Just change those fractions into decimals to make them easier to manage...

$(1)/(4) =0.25$
and
$(1)/(2) =0.50$

Leaving you with: 0.25,0.75,0.50, and 1.

Now, plot..

0 | | | | | | | | | | | | | 1

(0.25) (0.50) (0.75) (1)

Easy. :D

Solutions

Fractions have two part. The denominator and the numerator.

The denominator in a fraction represents the total number of equal size pieces that make up a whole. For example 7/12 of a foot means one foot is broken into 12 equal sized divisions.

The numerator in a fraction represents the number of pieces selected. If the numerator is larger than the denominator, the number is larger than one. For example, 15/12 of a foot is equivalent to

12/12 + 3/12 = 1 + 3/12 = 1 1/4.

A common denominator is needed when adding, subtracting and comparing fractions because each object needs to be cut into the exact same size pieces to be able to combine, remove or compare.

An opaque bag contains 5 green marbles 3 blue marbles and 2 red marbles. what is the of randomly picking out a marble and the marble being red?

Answers

The probability of randomly picking out a red marble is 1/5

Calculating the probability of randomly picking out a marble and the marble being red?

To determine the probability of randomly picking out a marble and it being red, we need to consider the total number of marbles and the number of red marbles.

Total marbles = 5 green + 3 blue + 2 red = 10 marbles

Red marbles = 2

So, we have

Probability = (Number of favorable outcomes) / (Total possible outcomes)

This gives

Probability = (Number of red marbles) / (Total marbles)

By subsituition

Probability = 2/10 = 1/5

Hence, the probability of randomly picking out a marble and it being red is 1/5
