A fire hydrant with a blue cap provides water at a rate of 1,500 gallons per minute. A fire hydrant with a green cap provides wa
ivann1987 [24]

Answer: 2b = 3g

Step-by-step explanation:

This is quite basic to solve, below is a Step by step explanation:

from the given question we have that;

  • A fire hydrant with a blue cap provides water at a rate of 1,500 gallons per minute.

       i.e  b = 1500 gallons per minute

  • A fire hydrant with a green cap provides water at a rate of 1,000 gallons per minute.

          g = 1000 gallons per minute.

Our questions tells us to write the equation which  relates the flow of water from the blue hydrant, b, to the flow from the green hydrant, g.

ANS:

Since flow from blue  hydrant b = 1500 gallons per minute, we have that

b = 3 * 500

b = 3 * 1000/2 g

b = 3/2 g

equation  gives 2b = 2g

cheers i hope this helped !!

Consider the equation 4•e^2.7x = 33
Yanka [14]

Answer:

\huge x =  ln( \frac{33}{4} )  \times  \frac{ 10}{27} \\  \huge \: x  \approx 0.782

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • logarithm
  • PEMDAS
<h3>let's solve:</h3>

4 {e}^{2.7x}  = 33 \\ {e}^{2.7x} =  \frac{33}{4}  \\ 2.7x =  ln( \frac{33}{4} )  \\ x =  ln( \frac{33}{4} )  \times  \frac{ 10}{27} \\ x  \approx 0.782
