Which arrangement shows −512 , −5 , −6.4 , and −264 in order from least to greatest? −264, −6.4, −5, −512 −512 , −6.4 , −264 , −5 −512 , −5 , −264 , −6.4 −264, −6.4, −512, −5

Answers

Answer:

-512, -264, -6.4, -5

Step-by-step explanation:

Since we need to go from least to largest, you would use the order above.

The order from least to greatest is -512, -264, -6.4, -5.

The given integers are −512, −5, −6.4 and −264.

What is ascending order of negative integers?

Ascending order of negative numbers means to arrange the given negative numbers from smallest to largest values.

It is very important to learn as in the case of negative numbers the absolute values of smaller numbers are greater than the absolute values of larger numbers, which makes it confusing.

Now, ascending order of given negative integers is as follows:

-512 < -264 < -6.4 < -5

So, the order from least to greatest is -512, -264, -6.4, -5.

Therefore, the order from least to greatest is -512, -264, -6.4, -5.

Your team is selling flowers to raise money for soccer. Your team has spent $250 on flowers and plans to sell them for $5 each. If your team sells 30 flowers, does your team make any kind of profit?​

Answers

----------------------------------------

Answer

Yes, $237

----------------------------------------

Step-by-step explanation:

First we do $250 divided by $5 = 50 Flowers (How much they would make) but they only sell 30 flowers, with 20 left over. With $12.5 loss. Since they spent $250 and lost $12.50 on leftovers. You would then do $250 - $12.50, $237.50

Therefore making $237.50 in profit.

Write a formula for the function g(x) obtained when the graph of f(x)=|x| is shifted down 7 units and to the right 13 units.

g(x)=?

Answers

9514 1404 393

Answer:

  g(x) = |x -13| -7

Step-by-step explanation:

The transformation ...

  g(x) = f(x -h) +k

represents a translation h units to the right and k units up. Here, we are translating 13 units to the right and -7 units up (that is, 7 units down). Then the transformed function is ...

  g(x) = f(x -13) -7

  g(x) = |x -13| -7

There are 20% more goblins than wizards in magic club. There are 220 goblins and wizards together in magic club. How many goblins are in magic club ?

Answers

Answer:

120

Step-by-step explanation:

w = wizards

1.2w = goblins

_________

w + 1.2w = 220

2.2w = 220

w = 100

This means there are 100 wizards. To find the number of goblins just plug the number of wizards in the goblins = 1.2w.

1.2 (100) = 120.

There are 120 goblins in the magic club.
