Answer:

2.05 cm

Step-by-step explanation:

3.14× (n+3)²×10 = 800

31.4(n+3)²=800

(n+3)²= 800/31.4

(n+3)²= 25.48

n+3 =√25.48

n+3= 5.05

n = 5.05 -3 = 2.05

so, the radius should be increased :

2.05 cm

32% of 35 pages please help
zepelin [54]
In order to answer this, first convert every percentage into decimal value.
The decimal value of 32% is 0.32. We just move two decimal places to the left.

Next move is to multiply the converted percent to the whole or total.
So,
= 0.32 * 35
= 11.2
Take note, there are no decimal pages. So the final answer is 11.
There are 11 pages.

Answer:

1)\frac{7}{12} 2)\frac{1}{4}  3)\frac{2}{12} 4)Rs.36 000

Step-by-step explanation:

1)1/3+1/4=4/12+3/12

             =7/12

2)remaining=12/12-7/12

                   =5/12

 other expenses=5/12*3/5

                            =1/4

3)total=7/12+1/4

          =7/12+3/12

          =10/12

          =5/6

remaining=6/6-5/6

                =1/6

fraction of the salary=1/6*2

                                  =2/12

4)1/6=rs.6000

   6/6=rs,36 000

Write Equivalent Fractions
Viktor [21]

Answer:

Step-by-step explanation:

Find equivalent fractions. Enter a fraction, mixed number or integer to get fractions that are equivalent to your input. Example entries:

Fraction - like 2/3 or 15/16

Mixed number - like 1 1/2 or 4 5/6

Integer - like 5 or 28

What are Equivalent Fractions?

Equivalent fractions are fractions with different numbers representing the same part of a whole. They have different numerators and denominators, but their fractional values are the same.

For example, think about the fraction 1/2. It means half of something. You can also say that 6/12 is half, and that 50/100 is half. They represent the same part of the whole. These equivalent fractions contain different numbers but they mean the same thing: 1/2 = 6/12 = 50/100

How to Find Equivalent Fractions

Multiply both the numerator and denominator of a fraction by the same whole number. As long as you multiply both top and bottom of the fraction by the same number, you won't change the value of the fraction, and you'll create an equivalent fraction.

Example Equivalent Fractions

Find fractions equivalent to 3/4 by multiplying the numerator and denominator by the same whole number:

34×22=68

34×33=912

34×44=1216

34×55=1520

34×66=1824

Therefore these are all equivalent fractions:

34=68=912=1520=1824

Note that if you reduce all of these fractions to lowest terms, they equal 3/4.

Answer:

20 √ 5

Step-by-step explanation:

1. You'll need to simplify each term. You'll get 32 √ 5-12 √ 5.

2. After you subtract  12 √ 5  from 32 √ 5, you'll get 20 √ 5.
