Most of the liquid water on earth is in the ocean, this water containing salt makes it unsafe for consumption, to make it safe to drink the water would have to be boiled, turn the water into a gas and leaving the salt from the water behind, and then the water must be cooled again so it returns to liquid form!

PLEASE HELP ME<br> Which expression is equivalent to –8(–5k+4)+6k
zheka24 [161]

Answer:

the last option (-5k+4)-8 + 6k

Step-by-step explanation:

-8(-5k+4)+6k

to simplify, begin by distributing the -8 so that parentheses are removed:

=(-8)(-5k) + (-8)(4) + 6k

=40k - 32 + 6k

combine 'like terms':

46k-32

the only answer which simplifies to 46k-32 is the last option:

the only difference between the original problem and the last option is that the -8 value is behind the parentheses instead of in front of it; it simplifies to be 46k-32

Torrance is shopping for a school party. His donation to the party is snack bags and juice boxes. Snack bags come in packages of
lara [203]

Answer:

Torrance must purchase 5 packages of snack bags and 6 packages of juice boxes.

Step-by-step explanation:

Given that:

Snack bags come in packages of 12.

Juice bags come in packages of 10.

To find:

Fewest number of packages of each product so that there are same number of snack bags and juice boxes.

Solution:

Number of snack bags when 1 package is bought = 12

Number of snack bags when 2 package is bought = 24

Number of snack bags when 3 package is bought = 36

Number of snack bags when 4 package is bought = 48

Number of snack bags when 5 package is bought = 60

Number of snack bags when 6 package is bought = 72

Number of juice bags when 1 package is bought = 10

Number of juice bags when 2 package is bought = 20

Number of juice bags when 3 package is bought = 30

Number of juice bags when 4 package is bought = 40

Number of juice bags when 5 package is bought = 50

Number of juice bags when 6 package is bought = 60

Number of juice bags when 7 package is bought = 70

We can see that when 5 packages of snack bags are bought and 6 packages of juice bags are bought, 60 bags of each are bought.

This can be found by finding the LCM as well.

LCM of 10 and 12 is 60.

It means we need to buy 60 bags of each item.

And we can easily find the number of packages for each.

Number of packages of snack bags to be bought = \frac{60}{12} =5

Number of packages of juice bags to be bought = \frac{60}{10} = 6

Torrance must purchase 5 packages of snack bags and 6 packages of juice boxes.

please show work. Use a trigonometric function to find the value of x. (Round your answer to the nearest tenth).​
Tatiana [17]

Answer:

x = 12.2

Step-by-step explanation:

sin theta = opp / hypotenuse

sin 55 = 10 /x

Multiply each side by x

x sin 55 = 10

Divide each side by sin 55

x = 10 / sin 55

x =12.20774589

Rounding to the nearest tenth

x = 12.2
