A box contains fiction and nonfiction books. There are 22 fiction books in the box, which is 55% of the total number of books in the box. What is the total number of books in the box?

thank you for helping

Answers

Answer 1

Answer:

There are 40 books total

Step-by-step explanation:

you need to set a proportion

The first fraction is 55/100 it's over 100 because it's percent

the other fraction is 22/x the 22 is out of a total number so that's why it's on top and x because you don't know the total number of books

then you multiply diagonally

55×x= 22×100

55x=2,200

Then you solve it like a regular equation by dividing both sides by 55

x=40

Answer 2

Answer:

There are a total of 40 books in the box.

How to find the answer to x+8=-52

Answers

subtract 8 from both sides. so you get x= -60

x + 8 = -52

   -8      -8       subtract 8 on both sides, 8's will cancel out on the left side.

_________    solve for -52 - 8, which is 60.

x = -60, final answer

Find the measure of CP

Answers

Given:

A figure ABCP.

To find:

The measure of CP.

Solution:

In triangles ABP and CBP,

[tex]\angle PAB\cong \angle PCB[/tex]            (Given right angles)

[tex]\angle ABP\cong \angle CBP[/tex]            (Given)

[tex]BP=BP[/tex]            (Common side)

Now,

[tex]\Delta ABP\cong \Delta CBP[/tex]        (By AAS property of congruence)

We know that the corresponding parts of congruent triangles are congruent.

[tex]AP=CP[/tex]

[tex]8=CP[/tex]

Therefore, the measure of CP is 8 units.

Angles a and b are ertical angles the measure of angle a is 8x+1 and angle b is 21-2x find each angle measure

Answers

Answer:

Angle a = 17°

Angle b = 17°

Step-by-step explanation:

Angles a and b are vertical angles the measure of angle a is 8x+1 and angle b is 21-2x find each angle measure

Vertical angles are angles that are equal to each other

Step 1

We find x

a = b

Hence,

8x+1 = 21-2x

Collect like terms

8x + 2x = 21 - 1

10x = 20

x = 20/10

x = 2

Step 2

We find each angle

Angle a

8x+1

x = 2

Angle a = 8(2) + 1

= 17°

Angle b

21-2x

x = 2

21 - (2 × 2)

= 21 - 4

= 17°

Therefore:

Angle a = 17°

Angle b = 17°
