# Asack of rice weight 49.5 kg what is the total weight of 8 sacks if they have thesame weight

Critical

the rate of each printer can be solved by analyzing the problem and using fractions or ratio and proportion.

step-by-step explanation:

q: how did you solve the rate of each printer?

given the following:

"you printed your 40-page reaction paper. you observed that printer a in the internet shop stopped printing in two "

from the text, we can know the rate of printer a.

rate = work done divided by the time it took to have the work done.

rate =

rate of printer a =

by using fraction or ratio and proportion, we can solve the following problems:

1. 45 pages = w minute/s

2. 150 pages = y minute/s

let w, y, be real numbers.

to solve for 1, we will equate the given rate with the problem. simply put:

=

by cross multiplication,

40w = 45 * 2

solving for w,

w =

w = = 2.25

the rate for 1 is equals to

to solve for 2,

=

by cross multiplication,

40y = 150 * 2

solving for y,

y =

w = = 7.5

the rate for 2 is equals to

" printer b can print x pages per minute, how long will it take to print p "

from the text, the rate of printer b is given.

rate of printer b =

1. 30 pages = r minute/s

2. 35 pages = s minute/s

let r, s, be real numbers.

to solve for 1, we will equate the given rate with the problem. simply put:

=

by cross multiplication,

x * r = 30 * 1

solving for r,

r =

r =

to solve for 2,

=

by cross multiplication,

x * s = 35 * 1

solving for s,

s =

s =

code: 8.3.1.2.1.

396 kg. is the total weight
