Answer:

Answer:

Step-by-step explanation:

x=total number of pages.

1)we calculate the total number of pages.

32% of x =80

(32/100)x=80

x=(80*100)/32

x=250.

2) we calculate the number of pages don´t read.

number of pages don´t read=250-80=170

Answer: 170 pages.

A rectangle has a perimeter of 68 inches it’s length is 2 inches less than 3 times the width what is the area of the rectangle

Answers

Answer:

225 inches²

Step-by-step explanation:

Let the length be l and width be w

Condition 1

2l+2w=68 (Perimeter=68)--------(i)

Condition 2

l=3w-2 ---------(ii)

Putting equation (ii) in (i)

2(3w-2)+2w=68

6w-4+2w=68

8w-4=68

8w=68+4

8w=72

dividing both sides by 8

w=9 inches

now putting w=9 in (ii)

l=3(9)-2

l=27-2

l=25 inches

Now

Area of rectangle = l × w

=9 × 25

=225 inches²

Answer: Length = 25 in., width = 9 in.

took the quiz in K12

What is 22,119 rounded to the nearest hundred?

Answers

To round a number to the nearest hundred, you need to check the digit in the tenth position (the position right after the hundred position).
If the number in the tenth position is less than 5, then you convert all the digits after the hundred to zeros
If the number in the tenth position is equal to or greater than 5, then you will add one to the hundred and convert all digits after the hundred to zeros.

Applying this to the given number:
The number is: 22,119
The digit in the hundred position is: 1
we check the digit next to it (the tenth position): It is "1" which is less than 5
so, we just convert all digits after the hundred to zeros
Therefore, 22,119 to the nearest hundreds is 22,100
