The expression 100 + 20m100+20m100, plus, 20, m gives the volume of water in Eduardo's pool (in liters) after Eduardo spends mmm

hodyreva [135]

Answer:

205 litres

Step-by-step explanation:

Given:

Volume of water is given as:

$V=100+20m$ (in litres)

<em>m</em> is the time in minutes spent filling water in Eduardo's pool.

To find:

Volume of water in the pool after the water is filled for $5\frac{1}{4}$ minutes.

Solution:

Here, volume of water in the Pool (in litres) is given by the equation:

$V=100+20m$ ....... (1)

Where m is the time for which Eduardo fills the pool.

Here, we are also given that

m = $5\frac{1}{4}$ minutes = $\frac{5\times4+1 }{4}=\frac{20+1}{4}=\frac{21}{4}$ minutes

And we have to find the value of V after $\frac{21}{4}$ minutes.

Let us put the value of m as $\frac{21}{4}$ minutes in the equation (1) to find the value of V.

$V=100+20m\\\Rightarrow V = 100 + 20 \times \frac{21}{4}\\\Rightarrow V = 100+105\\\Rightarrow \bold{V = 205\ litres}$

So, the volume of water in the pool after $\frac{21}{4}$ minutes is <em>205 litres.</em>

frez [133]

constraint 1
let
x = number of cups of chocolate
y = number of cups of vanilla
The equation that represents the total number of ice cream is:
x + y = 24
constraint 2
the ratio of the number of chocolate cups to vanilla cups is
y = (1/2) x
Using equations 1 and 2, you can find the number of cups of each favor required.
answer:
x + y = 24
y = (1/2) x
