What is the same-side interior angle theorem?

The same-side interior angle theorem states that when two lines that are parallel are intersected by a transversal line, the same-side interior angles that are formed are supplementary, or add up to 180 degrees.

According to the question

4x , 5x are angles given

As,

They are angles between  parallel line and same side of transversal line  

according to same-side interior angle theorem that are formed are supplementary .

i.e  there sum = 180°

4x + 5x= 180°

9x = 180°

x = 180°/9

x = 20°

So,

4x = 20 * 4 = 80°

5x = 20 * 5 = 100°

Hence, The value of 4x and 5x is 80° and 100° respectively .

Is it possible for two numbers to have a difference of 5, and a sum of 12?

Answers

Answer:

yes, 8.5 and 3.5

Step-by-step explanation:

8.5 + 3.5 = 12

8.5 - 3.5 = 5

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The two numbers are 8.5 and 3.5.

Yes, it is possible to have two numbers that have a difference of 5 and a sum of 12.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 4 is an equation.

3x = 4 + 3 is an equation.

We have,

Let the two numbers be M and N.

Now,

Two numbers have a difference of 5.

This can be written as,

M - N = 5 _____(1)

Two numbers sum is 12.

This can be written as,

M + N = 12 _____(2)

From (1) and (2) we get,

M - N = 5

M = 5 + N _____(3)

Putting (3) in (2)

M + N = 12

5 + N + N = 12

5 + 2N = 12

2N = 12 - 5

2N = 7

N = 7/2

N = 3.5

Putting in (3) we get,

M = 5 + 3.5

M = 8.5

We can cross-check.

M - N = 5

8.5 - 3.5 = 5 (PROVED)

M + N = 12

8.5 + 3.5 = 12 (PROVED)

Thus,

The two numbers are 8.5 and 3.5.

Yes, it is possible to have two numbers that have a difference of 5 and a sum of 12.

A certain stock has grown continuously from 1980 to 2015. A $10,000 investment in the stock in 1980 would be worth $3,500,000 in 2015. Find the stock's average annual growth rate during this period. Round to the nearest percent.

Answers

If a certain stock has grown continuously from 1980 to 2015, for this period of time  its average annual growth rate   is 18%.

It is given that A certain stock has grown continuously from 1980 to 2015.

Stock's initial value in 1980 (I) = $10,000

Stock's final value in  2015 (F) = $3,500,000

time period t = 2015-1980 = 35 years.

Since, the stock has grown continuously,  it should have grown compounded annually.

Stock's average annual growth rate (r) is calculated as:

[tex]\text{r} = {(\dfrac{F}{I})^{\frac{1}{t}}-1[/tex]

Substitute all the given values in the above formula:

[tex]\text{r} ={ (\dfrac{3500000}{10000})^{\frac{1}{35}}-1[/tex]

[tex]\text{r} = {(350})^{\frac{1}{35}}-1[/tex]

[tex]r = (350)^{0.02857142857}-1[/tex]

[tex]r=1.18219102629-1[/tex]

[tex]r=0.18219102629[/tex]

A librarian sorts 450 books at a constant rate. After 4 days, the librarian still has 150 books to sort. How much time does it take to sort the books from start to finish?

Answers

Answer:

Step-by-step explanation:

hope this helps

A librarian sorts 450 books at a constant rate. After 4 days, the librarian still has 150 books to sort. Then 6 days  time does it take to sort the books from start to finish

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The librarian sorted at a constant rate, then they sorted the same amount of books all 4 days.

450-150=300

If they still have 150 books left to sort, then they sorted 300 books over 4 days.

300/4=75

This means that they sorted 75 books per day.

150 divided by 75 is 2

So it will take 2 more days to finish sorting all the books.

So altogether, it will take 6 days to sort all of the books.

Hence 6 days time does it take to sort the books from start to finish

What is the distance?

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

It is given that:

Grayson biked 45 miles in 3 hours. Maya bikes 26 miles in 2 hours.

As we know,

The speed = distance/time

Plug the respective values in the above formula:

For Grayson:

speed = 45/3 = 15 miles/hour

For Maya:

speed = 26/2 = 13 miles/hour

Difference in speed = 15 - 13 = 2 miles/hour

Thus, Grason's Bike is 2 miles/hour faster than Maya's if Grayson biked 45 miles in 3 hours. Maya bikes 26 miles in 2 hours.
