The combined weight of all the samples can simply be calculated by the arithmetic sum of all the individual weights of each sample.

The total combined weight of all the samples is "114.22 lb".

Adding the individual weights of each sample we get:

Combined weight = Weight of sample 1 + Weight of sample 2 + Weight of sample 3

Combined Weight = 31.2 lb + 38.02 lb + 45 lb

Combined Weight = 114.22 lb

The attached picture shows weight addition.

Answer:

$\dfrac{dz}{dt}=0.65\ ft/s$

Explanation:

Given that

x= 150 ft

$\dfrac{dy}{dt}= 7\ ft/s$

y= 14 ft

From the diagram

$z^2=x^2+y^2$

When ,x= 150 ft and y= 14 ft

$z^2=150^2+14^2$

$z=\sqrt{150^2+15^2}$

z=150.74 ft

$z^2=x^2+y^2$

By differentiating with respect to time t

$2z\dfrac{dz}{dt}= 2x\dfrac{dx}{dt}+2y\dfrac{dy}{dt}$

$z\dfrac{dz}{dt}= x\dfrac{dx}{dt}+y\dfrac{dy}{dt}$

Here x is constant that is why

$\dfrac{dx}{dt}=0$

$z\dfrac{dz}{dt}= y\dfrac{dy}{dt}$

Now by putting the values in the above equation we get

$150.74\times \dfrac{dz}{dt}=14\times 7$

$\dfrac{dz}{dt}=\dfrac{14\times 7}{150.74}\ ft/s$

$\dfrac{dz}{dt}=0.65\ ft/s$

Therefore the distance between balloon and observer increasing with 0.65 ft/s.

The velocity of a body is given by the equation v= a + bx, where 'x' is displacement. The unit of b is .......

valina [46]

Answer:

s^ -1 ( or 1/sec)

Explanation:

Velocity is given in units of displacement / sec

like feet /sec or m/sec

so b would have units of s^-1

(or perhaps a more general term would be time^-1)

A description of both speed and direction

julia-pushkina [17]

Speed most often describes acceleration or a high rate of motion. ... As a verb, it means to “move along quickly,” like how you speed around on your bike. Direction is defined as the path that something takes, the path that must be taken to reach a specific place, the way in which something is starting to develop or the way you are facing
