A grocer mixed walnuts worth $1.02 per pound with peanuts worth $0.99 per pound. If she made 69 pounds of a mixture worth $1 per
Nataly [62]
The cost of the mixture is $69 *$1 = $69. If all 69 pounds were peanuts, the cost would be 69*$0.99 = $68.31, which is $0.69 less. Each pound of walnuts used instead of peanuts adds $0.03 to the cost of the mixture, so there were $0.69/$0.03 = 23 pounds of walnuts. 
<span>_____ </span>
<span>Let w represent the number of pounds of walnuts in the mixture. Then 69-w is the number of pounds of peanuts. The cost of the mixture will be </span>
<span>1.02w + 0.99(69-w) = 1.00*69 dollars </span>
<span>0.03w + 68.31 = 69.00 </span>
<span>w = (69.00 - 68.31)/0.03 = 0.69/0.03 = 23</span>

Inessa05 [86]

Considering the withdraws and credits, Lucia's current available balance is of $65.53.

<h3>How do we find a balance?</h3>

It is given by the sum of the money that the people has with the pending credits, and subtracted by the pending withdraws.

In this problem, we have that:

  • Lucia has $412.76, with pending credits of $134.00.
  • She has pending withdraws of $481.23.

Hence, her avaiable balance is given by:

412.76 + 134 - 481.23 = $65.53.

Andy and Christopher are measuring a liquid solution using graduated cylinders, Andy uses 3.5 liters of the liquid solution, and
Gre4nikov [31]

Answer:

Ratio = 0.74

Step-by-step explanation:

Represent

- Andy with A

- Christopher with C

A = 3.5L

C = 2580mL

Required

Determine the ratio of C to A

Ratio is represented as thus:

Ratio = C:A

Rewrite as fraction

Ratio = \frac{C}{A}

This gives

Ratio = \frac{2580mL}{3.5L}

Convert L to mL

Ratio = \frac{2580mL}{3.5*1000mL}

Ratio = \frac{2580mL}{3500mL}

Ratio = \frac{2580}{3500}

Ratio = 0.73714285714

Ratio = 0.74 --- Approximated

A new car is purchased for 17000 dollars. The value of the car depreciates at 12.25% per year. What will the value of the car be
Scilla [17]

Answer:

P(t=14) = 17000 (1-0.1225)^{14}= 2728.404

Step-by-step explanation:

for this case we have the following model for the cost of the car:

P(t) = P_o (1-r)^t

Where P_o is the initial amount on this case 17000, t the amount of years after the initial year and r the depreciation rate on this case:

r= \frac{12.25}{100}=0.1225

And for t =14 we can replace into the equation and we got:

P(t=14) = 17000 (1-0.1225)^{14}= 2728.404
