Divide the numerator by the denominator. <span>Write down the whole number answer.<span>Then write down any remainder above the denominator.
So example:
12/3= 4

You just divide
Example 1/2=.5

A tank contains 60 kg of salt and 1000 L of water. Pure water enters a tank at the rate 6 L/min. The solution is mixed and drain

andrey2020 [161]

Answer:

dy/dt = 7y / (t − 1000)

Step-by-step explanation:

Change in mass of salt = mass of salt going in − mass of salt going out

dy/dt = 0 − (C kg/L × 7 L/min)

where C is the concentration of salt in the tank.

The concentration is mass divided by volume:

C = y / V

The volume in the tank as a function of time is:

V = 1000 + 6t − 7t

V = 1000 − t

Therefore:

C = y / (1000 − t)

Substituting:

dy/dt = -7y / (1000 − t)

dy/dt = 7y / (t − 1000)

If we wanted, we could separate the variables and integrate. But the problem only asks that we find the differential equation, so here's the answer.

vfiekz [6]

Answer:

8 hours

Step-by-step explanation:

rental fee = 12 + 4/hr

spent = 44

44 = 12+4(hr)

32 = 4(hr)

32/4 = hr

hr = 8

A detective knows what time of day it is based on the angle at which the sun is hitting a man. Suppose a detective is looking at

soldi70 [24.7K]

Answer:

The angle $\theta$ at which the sun is hitting the ground is:

$\theta\approx 59.74^o$

Step-by-step explanation:

You can use right angle trigonometry to solve this, since the man (6 ft tall) and the shadow on the ground (3.5 ft long) form a right angle triangle as shown on the attached image.

The use the tangent function to find the angle that the sun's rays make with the ground:

$tan(\theta)=\frac{opposite}{adjacent} \\tan(\theta)=\frac{6}{3.5} \\\theta=arctan(\frac{6}{3.5})\\\theta\approx 59.74^o$
