Answer

500

Step-by-step explanation:

If the biologist tags 25 birds and lets them go, and then catches 100 and 5 of them have the tags, that would mean 20 of them are still out in the wild.

The way to solve this is if you put it into a proportion.

5/100 = 25/x

5x = (100)(25)

5x = 2500

5x/5 = 2500/5

x = 500

5/100=25/500

Kristin poured 6 ounces of lemonade into each of 19 glasses. Exactly how many ounces of lemonade did Kristin pour into all these
andriy [413]

Answer:

114

Step-by-step explanation:

If Kristin poured it in 19 cups and your figuring out how many in total, you’d have to multiply. I did an area model, to solve this, and 10 x 6 = 60, 9 x 6 = 54. Then we add 60 + 54 and get 114 as our answer. (I calculated so I’m sure I’m correct)

Please help! If the current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms, what is the voltage?
Leona [35]

The value of the voltage is 18 - j volts if the current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms option (c) is correct.

<h3>What is a complex number?</h3>

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

We have:

The current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms.

As we know,

V = IR

V = (3 + j2)(4 - j3)

\rm V=\left(3\cdot \:4-2\left(-3\right)\right)+\left(3\left(-3\right)+2\cdot \:4\right)j

j² = -1 (complex part)

After simplification:

V = 18 - j  volts

Thus, the value of the voltage is 18 - j volts if the current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms option (c) is correct.
