the total surface area of a solid is the sum of all faces both the bottom (base) and the top

Answer:

False

Step-by-step explanation:

The origin is at 0 on the x-axis, and 0 on the y-axis. Hence, (0,0) lies on both the axis.

hope this helps and is right. p.s. i really need brainliest :)

if my answer is wrong then i am incredibly sorry!

The statement "The origin is a point anywhere along the x-axis" is False.

Origin is referred to as the first point or the starting point from which we begin our calculations or measurements in mathematics, particularly in the subject of coordinate geometry. The 0 on a ruler is the point at which we begin taking measurements; as a result, it is referred regarded as the scale's origin.

As, The intersection of the x and y axes in a coordinate plane is where the origin is located.

Coordinates can be used to name any point on the coordinate plane.

The coordinates are where the origin is ( 0, 0 ).

So, the x- coordinate is 0 and y- coordinates is 0.

Hence, the given statement is False.

There are 362,880 ways to ducklings line up.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A mother duck lines her 9 ducklings up behind her.

Now,

Since, A mother duck lines her 9 ducklings up behind her.

Hence, By using Fundamental counting principal we get;

The number of ways for ducklings line up = 9!

                                                                 = 9×8×7×6×5×4×3×2×1

                                                                 = 362,880

Thus, The number of ways for ducklings line up = 362,880

Answer:In my opinion 10 is the answer

hope it helps you

Answer:

600 sq.ft.

Step-by-step explanation:

10 * 24 = 240 / 2 = 120

20*24 = 480

480+120 = 600

600 sq.ft.

Answer:

720

Step-by-step explanation:

So there are two things you need to remember to sovle this problem.

First, the formula for area of a square. This is just base x height.

Second, the formula for area of a triangle. THis is just 1/2 x base x height.

Lets plug our values into both formulas and see what we get.

So the area of the square would be:

24 x 20.

This is 480.

Now that we know the area of the square is 480, lets find the area of the traingle:

1/2 x 24 x 20

This will get you 240.

Low lets just add the two together, and we get:

240+480=720

So the area is:

720

Answer:

A) (-3, -4)

Step-by-step explanation:

f= the original amount of people, a steady growth throughout the years

t=time

In 1955 the population was 12 thousand. Compared to the current population of 12.36 thousand, the population then was roughly 77%.

A function assigns the values.  The population of the town in 1955 was 12 thousand people, and the percent increase in population from year to year was 3%.

A function assigns the value of each element of one set to the other specific element of another set.

The function that gives the population of the town is given, therefore, the following can be written,

Since the year 1955 the value of t=0. Therefore, The population of the town in 1955 was 12 thousand.

The percentage increase in population from year to year is 3%.

Hence, The population of the town in 1955 was 12 thousand people, and the percent increase in population from year to year was 3%.

Answer:

Step-by-step explanation:

If you are talking about a die with 6 faces, then 16 isn't possible. 12 is the highest possible number.

If you are talking about some other kind of die, you have to specify it.

I'm going to assume you made a mistake and meant 6.

There are 5 ways to get six

3 - 3

4 - 2

2 - 4

5 - 1

1  - 5

There are  36 ways of throwing 2 dice.

So the probability = 5/36 = 0.1389

If you really did mean 16 then the probability = 0

Answer:

"2.82" seems to be the correct solution.

Step-by-step explanation:

As we know,

A bag (Bag A) contains,

Red balls = 3

Blue ball = 1

A second bag (Bag B) contains,

Red balls = 1

Blue ball = 1

Now,

⇒ P(Bag A, red ball) = [tex]P(A)\times P(r)\times P(r)[/tex]

On substituting the values, we get

⇒                                = [tex]\frac{1}{2}\times \frac{3}{4}\times \frac{2}{3}[/tex]

⇒                                = [tex]\frac{1}{4}[/tex]

Similarly,

Probability of second bag will be:

⇒  P(Bag B) = [tex]\frac{1}{2}[/tex]

hence,

In the first bag (Bag A), the expected number of red balls will be:

⇒  [tex]E(n)=\Sigma P(n)\times n[/tex]

On substituting the values, we get

⇒           [tex]=3 (\frac{1}{4})+2(\frac{1}{8} )+4(\frac{1}{24} )+3(\frac{1}{12} )+3(\frac{4}{20} )+4(\frac{1}{20} )+2(\frac{3}{20} )+\frac{2}{20}[/tex]

⇒           [tex]= \frac{169}{60}[/tex]

⇒           [tex]=2.82[/tex]

Answer:

this is your answer as it lies in a same ratio..

Step-by-step explanation:

If X=-1, then we have to multiply by -10 and then add 2. It would be 8.

If X=0, we multiply it by -10, (still 0) and then add 2 so it would be 2.

If X=1, 1*-10=-10 and then -10+2=-8

If X=5, 5*-10=-50, -50+2=-48.

Step-by-step explanation:

Answer:

1 reactants    2 products

Step-by-step explanation:

Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

A chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.

Answer:

63/100

Step-by-step explanation:

Answer:

5) x = 25

6) x = 48

Step-by-step explanation:

5)

65 + x = 90

65 - 65 + x = 90 - 65

x = 25

--------------------------------------

6)

A complementary angle is 90 degrees.

42 + x = 90

42 - 42 + x = 90 - 42

x = 48

If triangle ABC is equilateral then the value of x is 3.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

ABC is an equilateral triangle.

AD is the perpendicular bisector of CB

As AC=8 units.

The other sides of triangle will be also 8 units.

D will be the midpoint of CB.

CD=4 units and DB is 4 units.

Let us consider triangle ACD

AC²=CD²+AD²

8²=4²+x²

64=16+x²

Substitute 16 from both sides.

64-16=x²

48=x²

Take square root on both sides.

x=√48

=√16×3

=4√3

Hence, if triangle ABC is equilateral then the value of x is 3.
