A gumball machine has different flavors sour apple,grape,orange and cherry . There are six of each flavor. $.50 are put in the m

tamaranim1 [39]

Answer:

30/552

Step-by-step explanation:

In order to solve this problem you need to multiply the probability of getting grape for the first gumball with the probability of getting grape for the second gumball. Since there are 6 grape gumballs and a total of 24 gumballs (6*4). Then the probability of getting grape for the firs one is

$\frac{6}{24}$

Now there are only 5 grape gumballs available and one less in the total supply, therefore the probability of getting grape in the second try is

$\frac{5}{23}$

Finally we multiply them together to find the probability of getting two grapes in a row.

$\frac{6*5}{24*23}$ = $\frac{30}{552}$

A certain corporation listed their sales in 100s as 20700. What was their actual volume in millions?

Mariana [72]

Answer: Their actual volume in millions is 207×10⁹.

Step-by-step explanation:

Since we have given that

A certain corporation listed their sales in 100s as 20700

We need to find their actual volume in millions,

According to question,

In 100s, their volume = 2070000

In 100000, their volume is given by

$207\times 10^5\\\\=2070000\times 10^5=207\times 10^9$

Hence, their actual volume in millions is 207×10⁹.

Troy cut a 100 foot rope into 3 pieces. The first piece is 43 foot long. The second piece is at least 22 feet long, but no great

Inessa05 [86]

Answer:

x=4

Step-by-step explanation:

Let he first piece be x the second be 3x and the very last one be 7x + 2

Add all the pieces together and you ought to get the length of the rope which is 46 ft

So your equation would be

x + 3x + 7x + 2 = 46

11x = 44

x = 44 / 11

x = 4

so the 3 pieces are 4 , 12 and 30ft
