8/15 multiplied by 5/6

Answers

To multiply two fractions, we multiply the top number (numerators) together and the bottom numbers together (denominators) and then simplify.

8 x 5 = 40
15 x 6 = 90

40/90 can be simplified (÷10) to 4/9
8/15×5/6
=8/18

If 12 eggs cost $2.04 how much with 18 eggs cost

Answers

the answer is 3.06 because u divide the 2.04 and the 12 and get 0.17
then u multiply that with 18
tada!
If 12 eggs cost $2.04, you need to figure out how much 1 egg cost. In order to do that, you need to divide the cost ($2.04) by the amount of eggs (12):

(2.04)/(12) = 0.17

1 egg = 0.17

Now that we know how much 1 egg costs, we need to take that number and multiply it by 18:

0.17 * 18 = 3.06

In this case, 18 eggs will cost $3.06.

Sir Dwayne is in charge of dragon designs at the King's ToyFactory. He hopes that his new designs will please the king
*Your Highness," he says. "I have the plans for the toy
dragons. If it pleases you, every 3rd dragon shall billow
clouds of smoke through its nostrils. every 4th dragon shall
breathe fire, every 6th dragon shall have glowing eyes, and
every 8th dragon shall have a tail with spikes on it. i shail
make 100 dragons." The king asks. Sir Dwayne, how many
dragons shall have more than one of these
characteristics?" Sir Dwayne doesn't have the answer. Can
you help him answer the king before he is thrown into the
dungeon?

Answers

Answer:

  • 24 dragons

Explanation:

Any multiple of 3 and 4shall blow clouds of smoke through its nostrils and breathe fire. Those are:

  • the 12th, the 24th, the 36th, the 48th, the 60th, the 72nd, the 84th, and the 96th dragons.

Hence, that is 8 dragons that shall have both characteristics.

Any multiple of 6 shall have glowing eyes. The common multiples of 6 and 3 are: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, and 96.

Then, that adds:

  • the 6th, 18th, 30th, 42nd, 54th, 66th, 78th, and the 90th dragons:

Hence, add 8 more dragons.

And the common multiples of 6 and 4 are: 12, 24, 36, 48, 60, 72, 84, and 96, all of which are already included.

Any multiple of 8 shall have a tail with spikes on it. Then, you must find the common multiples of 8 and 3, 8 and 4, and 8 and 6.

Common multiples of 8 and 3 are: 24, 48, 72, and 96, which are already included.

Common multiples of 8 and 4 are: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, and 96. Then, you must add:

  • the 8th, the 16th, the 32th, the 40th, the 56th, the 64th, the 80th, and the 88th.

Those are other 8 dragons.

At the endthe number of dragons that shall have more than one of these characteristics is:

  • 8 + 8 + 8 = 24

Solve (x + 1 < 5) ∩ (x - 4 > -3).

Answers

Answer:

(1, 4)

Step-by-step explanation:

(x + 1 < 5) is solved by subtracting 1 from both sides of this inequality:

x < 4.

(x - 4 > -3) is solved by adding 4 to both sides:  x > 1.

The solution of (x + 1 < 5) ∩ (x - 4 > -3) is thus (1, 4).

The gym teacher uses tape to mark a 4-square court on gym floor, as shown. The outerthe side lengths of 16 feet. What is the total length of tape the teacher uses to mark square A ?

Answers

32         16÷2=8×4=32 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
im assuming that square A and C are identical. therefore, they have the same sidelengths and since their sidelengths add to 16, each square must have sidelength 8. now the total length of tape used to mark square A is the perimeter of square A which is 8 + 8 + 8+ 8 = 32. we know each side is 8 cause it's a square and squares have equal sides of equal lengths.

let me know if you have any questions!!!
