30 people want soda, how many 2 liter bottles do you you need so everyone but you have 300 ml glass's of soda?

1 answer:

8 0

30 people want 300 ml of soda. To find the total amount of soda we will need, we have to multiply the amount of soda (300 ml) by the number of people drinking soda (30).

300 * 30 = 9000 ml

We know that there are 1000 milliliters in a liter.

9000 ml / 1000 = 9 Liters

We know that we need 9 liters of soda for the 30 people.

However, the question asks how many 2 liter bottles you will need.

9/2 = 4.5

Therefore, you will need 4.5 two - Liter bottles of soda. (Some teachers may say that you can't buy half of a bottle of soda, so in that instance you would just buy 5 two-liter bottles.)

Answer:

D. $1000 - 100w \geq 500; w \leq 5$

Step-by-step explanation:

Given:

Initial amount in the bank = $1000

Money withdrawn each week = $100

Final amount should be at least $500.

Now, let the number of weeks the money is withdrawn be 'w'.

Therefore,

Money withdrawn in 'w' weeks = $\textrm{Money withdrawn each week}\times w$

Total Money withdrawn in 'w' weeks = $100w$

Now, final amount after 'w' weeks is equal to the difference between initial amount and total withdrawal amount. Therefore,

Final amount = Initial amount - Total withdrawal amount

Final amount = $1000 - 100w$

Now, final amount must be greater than or equal to $500. So,

$\textrm{Final amount}\geq500\\\\1000-100w\geq500$

Therefore, the inequality that represents the inequality for the number of weeks Amy can withdraw money is:

$1000-100w\geq500$

Now, let us solve for 'w'.

Adding -500 and 100w both sides, we get:

$1000-500-100w+100w\geq500-500+100w\\\\500\geq100w\\\\\textrm{The above inequality is reversed when taking 100w on the left side}\\\\100w\leq500\\\\w\leq\frac{500}{100}\\\\\therefore w\leq5$

Therefore, the correct option is (D).

Find the endpoint P of a line segment whose midpoint Q lies at (5, -10) and whose other endpoint lies at (-8, -4). Write it as a

blondinia [14]

P is (18, -16)

to find the answer, u would solve it in reverse order of the midpoint formula by first doing the x-values:

5(2)= 10-(-8) = 18

and then the same to y-values:

-10(2)= (-20)-(-4) = -16

to get:

(18, -16)
