Answer:

Number of jars can be filled from 15kg of the salt = 468 or 469 jars (Approx.)

Step-by-step explanation:

Given:

Amount of salt containing in jar = 32 gram

Total amount of salt in jar = 15 kg

Find:

Number of jars can be filled from 15kg of the salt

Computation:

Total amount of salt in jar = 15 kg

Total amount of salt in jar (in grams) = 15 x 1000 g

Total amount of salt in jar (in grams) = 15,000 g

Number of jars can be filled from 15kg of the salt = Total amount of salt in jar (in grams) / Amount of salt containing in jar

Number of jars can be filled from 15kg of the salt = 15,000 / 32

Number of jars can be filled from 15kg of the salt = 468.75

Number of jars can be filled from 15kg of the salt = 468 or 469 jars (Approx.)

Solve and show your work for each question a). B). C).

Andreyy89

Answer:

Step-by-step explanation:

a) Here, the first term is .48 and the common ratio is 1/100 (since each new 48 is 1/100 th of the previous 48). a

Use the formula s = sum of geometric series = -----------

1 - r

0.48 48

which in this case is s = --------------- = ------------ = 48/99 = 16/33

1 - 1/100 100 - 1

Check this result by finding 16/33 on a calculator. Is the result equal to 0.484848484848.... ? Yes

b) Here we have the bar over the 8 only. 0.48 with the bar over the 8 is equivalent to 0.4888888888 ...

0.08

or 0.4 + 0.0888888888 ... or 0.4 + ------------

1 - 1/10

0.08 8

and this simplifies to 0.4 + ------------ = 0.4 + ---------

9/10 90

Evaluating this last result on a calculator results in 0.488888888 ...

c) 0.48 expressed as a fraction is 48/100 = 12/25

There are 30 boys in a sporting club. 20 of them play hockey and 15 play volleyball. Each boys plays at least one of the two gam

SVETLANKA909090 [29]

Answer:

5 boys play all the two games

25 boys play only one game

Step-by-step explanation:

Sets

There are two sets defined in the question: one for the boys who play hockey (H) and the other for the boys who play volleyball (V).

All the boys play at least one of the two games, so no elements are outside both sets.

There are 30 boys in total. 20 of them play hockey and 15 play volleyball. Since the sum of both numbers is greater than the total of boys, the difference corresponds to the boys who play both games.

Thus 20 + 15 - 30 = 5 boys play both games

Given that 5 boys are shared by both sets, from the 20 playing hockey, 15 play ONLY hockey. From the 15 boys playing volleyball, 10 play ONLY volleyball.

Thus 15 + 10 = 25 boys play only one game.
