The base of a right triangle is increasing at a rate of 2 meters per hour and the height is decreasing at a rate of 3 meters per

STatiana [176]

Answer:

dL/dt = - 2,019 m/h

Step-by-step explanation:

L² = x² + y² (1) Where x, and y are the legs of the right triangle and L the hypotenuse

If the base of the triangle, let´s call x is increasing at the rate of 2 m/h

then dx/dt = 2 m/h. And the height is decreasing at the rate of 3 m/h or dy/dt = - 3 m/h

If we take differentials on both sides of the equation (1)

2*L*dL/dt = 2*x*dx/dt + 2*y*dy/dt

L*dL/dt = x*dx/dt + y*dy/dt (2)

When the base is 9 and the height is 22 according to equation (1) the hypotenuse is:

L = √ (9)² + (22)² ⇒ L = √565 ⇒ L = 23,77

Therefore we got all the information to get dL/dt .

L*dL/dt = x*dx/dt + y*dy/dt

23,77 * dL/dt = 9*2 + 22* ( - 3)

dL/dt = ( 18 - 66 ) / 23,77

dL/dt = - 2,019 m/h

Water flowed out of a tank at a steady rate. A total of 18 1/2 gallons flowed out of the tank in 4 1/4 hours. Which expression

Alecsey [184]

Answer:

In 1 hour water flowed out = $\frac{74}{17}$ gallons

Step-by-step explanation:

Given as ,

The quantity of water flowed out of tank = 18 $\frac{1}{2}$ gallons

= $\frac{37}{2}$ gallons

The time spend in flowing water out of tank = 4 $\frac{1}{4}$ hours

= $\frac{17}{4}$ hours

∵ In $\frac{17}{4}$ hours , water flowed out = $\frac{37}{2}$

∴ In 1 hours , water flowed out = $\frac{37\times4} {17\times2}$

So, in 1 hour water flowed out = $\frac{74}{17}$ gallons Answer

Define the variables for the situation. Then enter an equation.

larisa [96]

Answer:

p = 16/8 = 2

Step-by-step explanation:

We know that the pencils were divided into 8 groups of 2.

Then the total number of pencils is equal to 8 (the number of groups) times 2 (the number of pencils in each group)

8*2 = 16

The total number of pencils is 16.

Then the operation of dividing 16 pencils into 8 groups is written as:

16/8

And we know that this is equal to 2, then the operation is:

16/8 = 2.

Then the equation is:

p = 16/8 = 2

where p represents the number of pencils in each group.
