An angle measures 40 more than the measure of its supplementary angle. What is the measure of each angle

Answers

Sum of two angles that are supplementary = 180°

Let the first angle be x .

Then the other angle = x + 40

Measure of each angle =

[tex]x + x + 40 = 180[/tex]

[tex]2x + 40 = 180[/tex]

[tex]2x = 180 - 40[/tex]

[tex]2x = 140°[/tex]

[tex]x = \frac{140}{2} [/tex]

[tex]x = 70°[/tex]

Which means :-

The first angle:-

[tex]= x = 70°[/tex]

The second angle :-

[tex]x + 40[/tex]

[tex]70 + 40[/tex]

[tex] = 110°[/tex]

Therefore , the two supplementary angles are 70° and 110° .

How much would it cost to make 25 shirts?


$ Answer


How much would students earn if they sold 25 shirts?


$ Answer


Will students make more money than they spent if they make and sell exactly 25 shirts?

Answers

Answer:

The answer is below

Step-by-step explanation:

The total cost for producing x number of shirts = 100 + 7x

The price of each shirt is $15, therefore:

Revenue = price per shirt × number of shirts = 15 × x = 15x

Revenue = 15x

The cost of making 25 shirts is given as:

Cost = 100 + 7x = 100 + 7(25) = $275

The money earned from producing 25 shirts is given as:

Revenue = 15x = 15(25) = $375

Since the revenue is greater than cost, the students would make more money than they spent if they make and sell exactly 25 shirts

Answer:

x < -8, third from top option in the picture.

Step-by-step explanation:

5(2x - 4) < -100

10x - 20 < -100

10x < -80

x < -8

Answer:

3rd option from the top (open circle arrow going left)

Step-by-step explanation:

5(2x-4) is less than - 100

5 times 2x is 10x and 5 times - 4 is - 20 so,

10x - 20 is less than - 100

now do inverse operations to isolate x, add 20

- 20 plus 20 is 0 and -100 plus 20 is - 80

10x is less than -80

divide both sides by 10 and you get,

x is less than - 8

For some reason, in our history class, there are 14 more boys than there are girls. If a total 32 students are in the class, how many boys and how many girls are there

Answers

Answer:

We can assume X is the number of girl, so the number of boy should be X+6.

 

Based on question, we can get X+X+6=32

2X+6=32

2X=26

X=13

So the answer is, 13 girls are in the class.

-Maggie turned right out of the school and drove 5 miles East to the store. She left the store and drove 2 miles North to Pelican's, then drove 5 miles South to her friend's house. When it was time to pick up her brother, she drove 7 miles West, then drove 4 miles North. Maggie and her brother then drove 2 miles East to get home. What is the displacement from Maggie's home to school?

Answers

Answer:

The school is at displacement of 1 mile towards South from the home.

Step-by-step explanation:

Let the origin, O, represents the location of the school.

Now, observe the attached figure for all the displacements as:

She drove 5 miles East to shore ( to point A)

So, OA=5 miles.

Then she drove 2 miles North to Pelican's ( to point B)

So, AB=2 miles.

Then she drove 5 miles South to her friend's house ( to point C)

So, BC=5 miles.

Then she  drove 7 miles West, to point D,

So, CD=7 miles.

Then she  drove 4 miles North, to point E,

So, DE=4 miles.

Lastly, she  drove 2 miles East, to reach home (the point F)

So, EF=2 miles.

Now computing the displacements in each direction.

The displacements in the East direction=OA+EF= 5+2= 7 miles

The displacements in the West direction =CD= 7 miles

As East and West are opposite to east other, so net displacements in the East direction = 7+(-7)=0, i.e the final point F ( home) is on the vertical axis as shown.

The displacements in the North direction=AB+DE= 2+4= 6 miles

The displacements in the South direction=BC=5 miles

As North and South are opposite to east other, so net displacements in the North direction = 6+(-5)= 1 miles which means final point F ( home) is located at 1 mile towards North from the school.

Hence, the school is at displacement of 1 mile towards South from the home.
