I need help to find this number in scientific notation form pls.

The first incorrect step is step 2 because this step did not take the two signs positive and negative.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have a linear equation in a mod function;

|2x - 3| - 1 = 2

Step 1:

|2x - 3| = 3

Step 2:

2x - 3 = 3 or 2x - 3 = -3

(after removing mod, we get two same values but opposite in sign)

The first incorrect step is step 2 in which did not take the two sign,

2x - 3= 3 or 2x + 3 = 3   (wrong)

Thus, the first incorrect step is step 2 because this step did not take the two signs positive and negative.

Answer:

The solution for the compound inequality is x \in(2,6)

Step-by-step explanation:

To find the solution set for these compound inequalities, we need to solve the inequality.

First, we shall solve the inequality

Adding both sides of the equation by 10, we have,

Dividing both sides by 3.5, we get,

Now, we shall solve the inequality ,

Adding both sides of the equation by 9, we have,

Dividing both sides by 8, we get,

The solution inequality for the given set of compound inequality 3.5x - 10 > - 3 & 8x - 9 < 39 is 2 < x < 6.

The general equation of a straight line inequalities are -

[y] < [m]x + [c]

[y] > [m]x + [c]

[y] ≥ [m]x + [c]

[y] ≤ [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have the following compound inequality -

3.5x - 10 > - 3

8x - 9 < 39

We have -

3.5x - 10 > - 3

8x - 9 < 39

3.5x - 10 > - 3

3.5x > 7

x > 2

AND

8x - 9 < 39

8x < 48

x < 6

Solution inequality -

2 < x < 6

Therefore, the solution inequality for the given set of compound inequality 3.5x - 10 > - 3 & 8x - 9 < 39 is 2 < x < 6.

Let's see

For initial cone

For new cone

Volume

So

Answer:

16 times

Step-by-step explanation:

[tex]\textsf{Volume of a cone}=\sf \dfrac{1}{3} \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}[/tex]

If only the radius is changed, the change in volume will be proportionate to the multiplicative factor squared.

[tex]\sf \implies Volume =\dfrac{1}{3} \pi (ar)^2h=\dfrac{1}{3} \pi (a^2)r^2h[/tex]

Therefore, if the cone is quadrupled (multiplied by 4), the volume of the larger cone will be 4² times greater than the volume of the smaller cone, so 16 times greater than the smaller cone.

Given:

Substituting the given values into the formula:

[tex]\sf \implies Volume =\dfrac{1}{3} \pi (6)^2(9)=108 \pi \: \:cubic\:units[/tex]

If the radius is quadrupled:

Substituting the new given values into the formula:

[tex]\sf \implies Volume =\dfrac{1}{3} \pi (24)^2(9)=1728 \pi \: \:cubic\:units[/tex]

To find the number of times greater the volume of the large cone is than the volume of the smaller cone, divide their volumes:

[tex]\sf \implies \dfrac{V_{large}}{V_{small}}=\dfrac{1728\pi}{108\pi}=16[/tex]

So the volume of the larger cone is 16 times greater than the volume of the smaller cone.

45000+7544644555=x

x=7544689555

Answer:

x = 7544599555

Step-by-step explanation:

First let's make an equation :

7544644555 - x = 45000

Now to make x the subject and positive :

We add x to both sides :

7544644555 = 45000 + x

Now we subtract 45000 from both sides :

7544644555 - 45000 = x

x = 7544599555

The probability that Jake will earn at least 30 points on a throw is 0.335

The attached image represents the missing part of the question.

From the attached image, we can see that:

For Jake to earn at least point, he must hit the three circles (starting from the inner circle)

The radius of the yellow circle is:

Radius = 3

While the width of the other circles is:

Width = 4

The total area of the sections that give a point of at least 30 is:

A₁ = π * (3 + 4 + 4)² = 121π

The total area of all the sections is:

A₂ = π * (3 + 4 + 4 + 4 + 4)² = 361π

The probability of getting at least 30 points is:

P(At least 30) = 121π/361π

Evaluate

P(At least 30) = 0.335

Hence, the probability that Jake will earn at least 30 points on a throw is 0.335

Answer:

64

Step-by-step explanation:

There are 4 options to choose from:

Each has a 1/4 chance of being picked.

For 3 times in a row, we would multiply the chance of being picked for one option, by whatever the other option's chance is.

As they all have the same chance, and it is 3 times in a row, we would do the following:

1/4 x 1/4 x 1/4

This is:

1/16 x 1/4

Which is:

1/64

Therefore, any possible combination has a 1/64 chance of occurring, meaning that there are 64 possible combinations that could be created.
