Answers

Answer 1
Answer: 5 x 2=10
10 (divided by) 2=5

Sorry i did not just put a division sign, my phone did not have the sign. :(
Answer 2
Answer:

Final answer:

Some fact families can have only a multiplication equation and one division equation.

Explanation:

Fact families are a set of related addition and subtraction or multiplication and division equations that use the same numbers. In a fact family, there are always four equations. However, it is possible for some fact families to have only a multiplication equation and one division equation.

For example, let's take the numbers 4, 2, and 8. The fact family in this case would be:

  1. 4 x 2 = 8
  2. 8 ÷ 2 = 4

These two equations represent the multiplication and division relationship between the numbers 4, 2, and 8.

carlos had 24 class play tickets to sell. he sold 3/4 of the tickets. how many tickets did carlos sell

Answers

18 because 4 x 6 is 24 so you would multiply 3 x 6 and get 18
Carlos sold 18 tickets because 

The answer is 18 but let me explain why that is. First of all let's assume (because it's true) that 3/4 is the same as saying 3/4 of one which is the same as saying 3/4 x 1 the answer then to that is 3/4 (go figure) so then using this logic we can say that 3/4 of 24 is the same as 3/4 x 24, which is an easy expression to evaluate if you have a calculator, but what if you don't, then what? Then you have to evaluate, 3/4 x 24 is the same as saying 3 x 24 = 72, then taking 72 and dividing by 4 which will give you 18, the answer. So I hope you can see the connection here, again if we have 3/4 of one we know that's the same as 3/4 x 1 which is equal to 1 x 3 = 3 then divided by 4 which is 3 divided by 4 which is the same as, you guessed, 3/4. Hope that helps, good luck with math in the future.

The volume of a cylinder, found using 3.14 to approximate pi, is 50,240 cm3. The radius of the cylinder is 40 cm.What is the height of the cylinder?



Express your answer as a whole number.

Answers

V=hpir^2
pi=3.14 for this quesiton
v=50240
r=40
subsitute and solve
50240=h(3.14)(40^2)
50240=h(3.14)(1600)
50240=h(5024)
divide both sides by 5024
10=h

answer is height=10cm

B. Compare and Contrast How are colloids and
suspensions different from solutions?

Answers

Step-by-step explanation:

Solutions, colloids and suspensions are the three main classifications of a mixture based on sizes of the particles.

  • A solution is a homogeneous mixture of solutes and solvents.
  • Suspensions are mixtures of small insoluble particles of a solid in a liquid or gas.
  • Colloids are homogeneous mixtures of two phases.

Solutions have the following characteristics:

  • The size of particles is small
  • The particles do not settle on standing.
  • The particles pass through ordinary filter papers.
  • They are clear and do not have color.
  • They do not scatter light

Suspensions have the following properties:

  • The particles dispersed are large
  • They settle on standing.
  • The particles do not pass through ordinary filter papers
  • They do not pass through permeable membrane
  • They are visible with microscope or naked eyes.
  • They are cloudy
  • Scatters light.

Colloids have the following properties:

  • Their particles are between those in solutions and suspensions.
  • Their particles do not settle on standing.
  • Their particles pass through ordinary filter paper.
  • They do not pass through permeable membranes.
  • Scatters light

Find the area of the semicircle.Either enter an exact answer in terms of or use 3.14 for
and enter your answer as a decimal.
units

Answers

Answer:

14.13

Step-by-step explanation:

The formula for area of a circle is πr^2.

This is a semicircle which is half a circle, so the formula for area of a semicircle is (πr^2)/2

The diameter of the circle is 6, which means that the radius is 3. Since the radius of a circle is always half the diameter. (1/2*6=3)

This means we can plug the known values into our formula.

π(3)^2/2

Simplify.

9π/2

Now we plug 3.14 in for π.

9(3.14)/2

28.26/2

14.13
So we know that the area of a full circle is pi multiplied by radius squared
But for a semicircle the area is pi multiplied by radius squared divided by two
So, we do 3.14*3^2/2
Which is 14.13
