Answer: 8 members of the science group decided to watch the science fiction movie

Step-by-step explanation:

When a group of 40 friends goes to the movies at a multiplex, 1/5 of the group decides to watch a science friction movie. This means that the total sum of the members of the group that decided to watch the science fiction movie and the members that did not watch the science fiction movie is 40.

If 1/5 of the group decides to watch a science friction movie, that means that 1/5 of 40 watched the science fiction movie. It becomes

1/5 × 40/= 40/5 = 8

8 members of the science group decided to watch the science fiction movie.

A quarter is 1/5 of an inch thick and 5 quarters weigh one ounce. Stephanie built a toothpick bridge that could safely hold 3 po
AleksandrR [38]

Answer:

Maximum height of quarter tower = 9.6 inches.

Step-by-step explanation:

The thickness of a quarter = \frac{1}{5} inches

Weight of a quarter = 1 ounce

The maximum weight that could safely hold = 3 pounds.

<u>The conversion factor for ounce to pound is 1 ounce = 0.0625 pound</u>

The number of quarter used in the tower = no of ounces equivalent to 3 pounds.

No of ounces equivalent to 3 pounds = \frac{3}{0.0625}

No of ounces equivalent to 3 pounds = 48

So the height of quarter tower = 48 \times \frac{1}{5} inches

                                                   = 9.6 inches.

Answer: A = 1,625.82 m³

Step-by-step explanation:

   The volume of a rectangular prism can be found with;
