Answer:

30 books on the shelf are Fiction.

Step-by-step explanation:

Hey!

There are 50 books on a shelf.

1/5 of the books are Science Fiction.3/10 are Non-Fiction.The Rest are Fiction.

how many books on the shelf are Fiction?

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

MAKE AN EQUATION!

We know that there are three Categories: Fiction, Science Fiction, and Non Fiction.

Total- 50

⇒ 50 =

1/5 of 50 are SF

⇒ 50 = (1/5)(50)

3/10 of 50 are NF

⇒ 50 = (1/5)(50) + (3/10)(50) + x

--------------------------------------------------------------------------------------------------------------

SOLVE THE EQUATION!

(1/5)(50) + (3/10)(50) + x = 50

To Isolate X-

  -Multiply and remove the parentheses..

⇒ 50/10 + 150/10 + x = 50

   -Simplify.

⇒ 5 + 15 + x = 50

   -Add Like Terms

⇒ 20 + x = 50

     -Subtract 20 from both sides.

⇒ 20 + x - 20 = 50 - 20

      -Simplify Right Hand Side.

⇒ x =  30

--------------------------------------------------------------------------------------------------------------

So, 30 books on the shelf are Fiction.

Find the missing angle on a quadrilateral. Angle C equals 80 degrees, Angle D equals 90 degrees, and angle E equals 135 degrees. What is the measure of Angle F?

Answers

all quadrilateral angles have to add up to a total of 360°, so we just need to add the angles we already have and subtract that from 360.
135+90+80=305
360-305=55 so your answer is 55!

Hallar x + y
Es de geoemtria, angulos

Answers

Answer:

1). x = 40

2). y = 20

Step-by-step explanation:

1). "4x" y "160" son ángulos de vértice, por lo que son congruentes entre sí. Entonces, "4x = 160" y luego usa álgebra para resolver "x" y "x = 40".

2). "Y" y "4x" son ángulos suplementarios, por lo que si ambos se suman, forman un ángulo de 180. Entonces, "Y + 4 (40) = 180", usando álgebra daría la respuesta "Y = 20".

$312.50

Answers

Answer:

$312.50

Step-by-step explanation:

1:    12,500 x .70 = 8,750

2:   12,500 - 8,750 =3,750

3:    3,750 ÷ 12 = 312.5

Bye Bye :)

The minimum amount that she should save each month in order to have enough money is $312.5

What is percentage?

A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction.

Given that, The cost of tuition at the college that Lacy wants to attend is $12,500 per year. Lacy’s family will pay 70% of the tuition cost each year. Lacy has two years to save enough money to attend her first year of college.

The amount Lacy have to pay = (70-30)% of 12500 = 30% of 12500

= 125×30 = $3750

Each month = 3750/12 =32.50

Hence, the minimum amount that she should save each month in order to have enough money is $312.5
