Answer:

If I'm reading the graph correctly, the temperature at 0 kilometers is 40. The correct statement is "as the height increases, the temperature decreases." This is shown by the line that's going down instead of up. The temperature is decreasing by -5 per kilometer.

If I'm wrong, feel free to correct me. :)

Work Rate One worker can complete a task in h hours while a second can complete the task in 3h hours. Show that by working toget
Sliva [168]

Answer: t = (3/4)h hours.

Therefore, it takes both of them (3/4)h hours to complete the task.

Step-by-step explanation:

Let

t1 represent the time taken for the one worker to complete a task.

t2 represent the time taken for the second worker to complete a task

And t represent the time taken for both.

t1 = h

t2 = 3h

Let x represent the task.

x = rate × time

r1,r2 and r are the rates at which first, second and both worker works

x = r1(t1). .....1

x = r2(t2). ....2

x = r(t) ....3

And,

r = r1 + r2. ( Rate of both equals sum of rates of the two)

From eqn 1 and 2

r1 = x/t1 = x/h

r2 = x/t2 = x/3h

r = r1 + r2 = x/h + x/3h = 4x/3h

Substituting r = 4x/3h into equation 3

x= r(t)

x = (4x/3h)t

Making t the subject of formula

t = x/(4x/3h)

t = 1/(4/3h)

t = 3h/4

t = (3/4)h hours.

Therefore, it takes both of them (3/4)h hours to complete the task.

Step-by-step explanation:

A quick way to divide by 0.5 or ½ is to double the number (or multiply number by 2). The reason for this is that two halves go into a whole.

The diameter of a spherical balloon that is being filled with air is increasing at the rate of 3 inches more than the time, t. W
bixtya [17]
It is given that the diameter of the sphere increases <span>at the rate of 3 inches more than the time, t. 
This means that:
at a certain time = t seconds
the diameter of the sphere will be equal to t + 3 

Based on this:
at t = 3 seconds
diameter of the sphere = t + 3 = 3 + 3 = 6 inches = </span><span>0.1524 meters
and radius of sphere = 0.5 x </span><span>0.1524 = 0.0762 meters

Volume of the sphere can be calculated using the following rule:
volume of sphere = (4/3) x pi x (radius)^3
Substituting in this equation, we can get the volume of the sphere at t = 3 seconds as follows:
volume at t=3 seconds = (4/3) x 3.14 x (</span>0.0762)^3 = 1.8533 x 10^-3 m^3
