Answer:

(A) Pi cannot be written as a ratio of integers even if it represents a different ratio.

Step-by-step explanation:

A rational number is can be expressed as the quotient of two integers. It can either be a number with or without a decimal part when converted to decimals.

C = 2 $\pi$ r and D = 2r

C = $\pi$ D

Thus, $\pi$ = $\frac{C}{D}$

= $\frac{22}{7}$ = 3.142857143...

Terrence was incorrect because Pi is an irrational number which cannot be represented by a simple fraction without approximation.

Demont made one fourth pound of rock candy.He will separate the candy into four stacks.If he puts an equal amount of candy in ea

kondor19780726 [428]

Answer:

1/16

Step-by-step explanation:

Demont made one fourth ( $\frac{1}{4}$ ) pound of rock candy

He separates the candy into four sacks equally.

This is done by dividing the total fraction of candy of a pound of candy made by the number of sacks

The fraction of a pound of candy that will be in each sack therefore is:

$\frac{1}{4}\div 4= \frac{1}{4}X\frac{1}{4}=\frac{1}{16}$

Therefore, One-Sixteenth of a pound of candy will be in each of the sack.

In computer technology, a kilobyte is 2^10 bytes in size . A gigabyte is 2^30 bytes in size . The size of a terabyte is the prod

melomori [17]

Kilobyte = 2^10 bytes
gigabyte = 2^30 bytes
terabyte is the product of a kilobyte and a gigabyte....so we multiply

2^10 * 2^30 = 2^(10 + 30) = 2^40 <== a terabyte

** exponent rule : a^b * a^c = a^(b + c)

PLEASEEEE

belka [17]

Answer:

The answer to your questions is: 25 new teachers

Step-by-step explanation:

Data

# of students = 2000

ratio = 3:80 teachers to students

New teachers = ?

Process

I suggest to use rule of three to solve this problem

3 teachers ---------------- 80 students

x ---------------- 2000 students

x = (2000 x 3) / 80 = 75 teachers

Number of initial teachers = 75

The ratio change to 1:20

1 teacher ------------------- 20 students

x ------------------- 2000 students

x = (2000 x 1) / 20

x = 100 teachers

Number of new teachers = 100 - 75 = 25
