2,200 years ago. He invented a method of finding prime numbers,
Eratosthenes was a Greek mathematician who lived more than
19. Follow the steps below to circle all prime numbers
every number is either
circled or crossed out.
Connect to Social Studies
The Sieve of Eratosthenes
which is now called the Sieve of Eratosthenes.
less than 100. Then list the prime numbers.
Repeat Step 3 until
STEP 1
Cross out 1, since 1 is
not prime
4.63
STEP 4
STEP 2
Circle 2, since it is
prime. Cross out all
other multiples of 2.
STEP 3
Circle the next
number that is not
crossed out. This
number is prime. Cross
out all the multiples
of this number,
7
So, the prime numbers less
than 100 are

45

step-by-step explanation:

yes.. it's proven to be 36.

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
