Answer 2

Answer:

x = 10.4 (nearest tenth)

Step-by-step explanation:

Angle Bisector Theorem

The angle bisector of any angle in a triangle will divide the side opposite the bisected angle in the ratio of the sides containing the angle.

Therefore:

AD : DC = BA : BC

Given:

AD = xDC = 11BA = 18BC = 19

Substituting the given values into the ratio and solving for x:

[tex]\implies \sf x : 11 = 18 : 19[/tex]

[tex]\implies \sf \dfrac{x}{11}=\dfrac{18}{19}[/tex]

[tex]\implies \sf 19x=18 \cdot 11[/tex]

[tex]\implies \sf 19x=198[/tex]

[tex]\implies \sf x=\dfrac{198}{19}[/tex]

[tex]\implies \sf x=10.4 \: (nearest\:tenth)[/tex]

Answers

Answer: 37 students in the class

Step-by-step explanation:

Let n = number of books,

Let s = number of students

1) |x-(-18)| if x<-18
2) |2x| if x<0
3) |x-120| if x<120

Answers

The results of the absolute value expressions are:

|x - (-18)| if x < -18 is greater than 0|2x| if x < 0 is greater than 0|x - 120| if x<120 is greater than 0

How to solve the absolute value expressions

Expression 1:

We have: |x - (-18)| if x<-18

Open the bracket

|x + 18|

If x < -18, then the values of x are above -18 i.e. -19, -20...

This means that: |x + 18| > 0

Hence, |x - (-18)| if x < -18 is greater than 0

Expression 2:

We have: |2x| if x < 0

If x < 0, then the above equation would be greater than 0

Hence, |2x| if x < 0 is greater than 0

Expression 3:

We have: |x - 120| if x<120

If x < 120, then the values of x are less 120 i.e. 119, 118...

This means that: |x - 120| > 0

Hence, |x - 120| if x<120 is greater than 0

It is to be noted that the area of the Trapezoid is: 28 Feet. See the details of the solution below.

What is the formula for the area of a Trapezoid?

The formula for the area of a regular Trapezoid is:

A = h * ((a+b)/2);

Where

A = Area

a  = Short Base

b = Long Base

h = Height

So what is the solution for the above trapezoid?

Following the above formula,

A = 4 * ((5+9)/2)

A = 4 * (14/2)

Find the equation of a line parallel to -x + y = -5 that passes through the point

Oy=x-5
O-x+y=-2
Submit Answer
Oy=-x-2
O-z-y=14

Answers

Answer:

O -x+y=-2

Step-by-step explanation:

-x + y = -5

⇔ y = x - 5

a line parallel to y = x - 5 must have the same slope as the line y = x - 5

Then

The equation of the parallel line is of the form : y = x + p

Finding p :

the point (-6,-8) lies on the parallel line means :

-8 = -6 + p

Then

p = -8 + 6 = -2

What is the circumference of the circle?

Answers

Answer:

Step-by-step explanation:

Since the tetherball is in the centre of the circle, any distance from it to the edge of the circle will be its radius. So, radius (r) = 5 ft.

Now, the formula for the cirumference of a circle = 2πr

Circumference of the circle

= 2πr

= 2 × 3.14 × 5                      [π = 3.14]
