Find the slope of the line

Answer:

x = 12

Step-by-step explanation:

Given a tangent and a secant from an external point to the circle, then

The square of the tangent is equal to the product of the external part and the entire secant, that is

x² = 6(6 + 18) = 6 × 24 = 144 ( take the square root of both sides )

x = [tex]\sqrt{144}[/tex] = 12

The conjugate number of the complex number 21 - 20i will be 21 + 20i.

The complex conjugate of a complex number is the number that has equal real and imaginary parts that are opposite in sign but equal in magnitude.

In mathematics, a complex number is a part of a number system that includes an element labeled I often known as the imaginary unit, and that extends the real numbers while satisfying the equation i2 = 1.

The given complex number is 21-20i. The conjugate complex number will be:-

21-20i = 21 + 20i

Therefore, the conjugate number of the complex number 21 - 20i will be 21 + 20i.

Answer: 3.5 meters

Step-by-step explanation:

First and foremost, we need to note that 1000 millimeters = 1 meter. Therefore, for us to convert 3500 millimeter to meters, we have to divide it by 1000. This will be:

= 3500/1000

= 3.5 meters

Answer:

-210

Step-by-step explanation:

The percent decrease in the time taken by Celesta is 33.33%.

Percentage of a number is the parts per 100. Or percentage of a number can be calculated by dividing the number with the whole with respect to which we are finding the percentage of the number and then multiply with 100.

Percentage is a dimensionless number because percentage is not measured by any units.

Percentage decrease can be calculated by the formula,

Percentage Decrease = [(Original value - New value) / Original value] × 100

Time that Celesta used to spend on the phone a day = 90 minutes

Original value = 90

Now, celesta spends 60 minutes a day

New value = 60

Percentage decrease = [(90 - 60) / 90] × 100

                                    = [30 / 90] × 100

                                    = [1 / 3] × 100

                                    = 33.33 %

Hence the percent decrease in the time taken by Celesta in a day is 33.33%.

======================================================

Explanation:

We have 6 green out of 6+6+6 = 18 total

The probability of getting green is 6/18 = 1/3.

After selecting that green jelly bean and not putting it back, we have 6-1 = 5 green out of 18-1 = 17 total.

The probability of selecting another green is 5/17.

Multiply the two fractions 1/3 and 5/17

(1/3)*(5/17) = (1*5)/(3*17) = 5/51

The probability of selecting two greens in a row is 5/51 where we do not put the first selection back. We also do not replace the green jelly bean with some other identical copy.

Note: 5/51 = 0.098039 approximately

Answer:

3.38pi

Step-by-step explanation:

Using simple math and the equation for finding the volume of a sphere, we can see that by taking the height of 10, and the volume of 30, that with that information we can deduce that the radius of the cone would be 1.69pi. With this information, we know the radius is half of the diameter. Therefore, we multiply 1.69 by 2, to get our end result, 3.36pi

Answer:

Step-by-step explanation:

A Perpendicular Bisector cuts a segment into two equal parts. We already know that 4x+19 and 6x-7 are both equal.

So then, you would start with 6x-7 = 4x+19.

6x-7 = 4x+19

Subtract -4x from both sides

2x-7 = 19

Add 7 to both sides

2x = 26

Divide both sides by two

x= 13

You only need x, so you're done.

(I'm like 90 percent sure this is wrong man don take my word for it bro).

The value of x will be 13.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

EF is the perpendicular bisector of CD.

Measure of length CE = 4x + 19

Measure of length ED = 6x - 7

Now,

Since,  EF is the perpendicular bisector of CD.

So, We can formulate;

⇒ Δ EFC ≅ Δ EFD

Hence, Measure of length CE = Measure of length DE

Substitute all the values, we get;

⇒ 4x + 19 = 6x - 7

Solve for x as;

⇒ 4x + 19 = 6x - 7

Subtract 6x both side, we get;

⇒ 4x - 6x + 19 = 6x - 7 - 6x

⇒ - 2x + 19 = - 7

Subtract 19 both side,

⇒ - 2x + 19 - 19 = - 7 - 19

⇒ - 2x = - 26

Divide by - 2, we get;

⇒ x = 13

Thus, The value of x will be 13.

Answer: Water in the container = 87.75 cu.inches.

Step-by-step explanation:

Formula: Volume of rectangular prism = Base area x height

Base area = [tex]19\dfrac12[/tex] sq. inches    Height = [tex]4\dfrac12[/tex] inches

So,

Volume of container = [tex]19\dfrac12\times4\dfrac12\text{ cu.inches}[/tex]

[tex]=\dfrac{39}{2}\times\dfrac{9}{2}\text{ cu.inches}[/tex]

[tex]=\dfrac{351}{4}\text{ cu.inches}[/tex]

[tex]=87.75\text{ cu. inches}[/tex]
