Hello from MrBillDoesMath!

Answer:

12/5

Discussion:

Note that 10 is a common denominator of both denominators:

9/5 = (9*2)/(5*2) = 18/10

- ( -6/10) = + (6/10)

So the original problem is equivalent to

18/10 + 6/10 =

(18 +6)/10 =

24/10 =

(2*12)/ (2*5) => cancelling the common factor "2"

12/5 =

2 and 2 fifths =

22/5 (though this looks like (22)/5!)

Thank you,

MrB

A rectangular prism has a width of 16 inches and a length of 10 inches. The volume of the rectangular prism is decreasing at a r

frosja888 [35]

Answer:

-3.47 inches per minute

Step-by-step explanation:

Let the height be 'h' for any time 't'.

Given:

Length of the prism (L) = 10 in

Width of the prism (w) = 16 in

The rate of change of volume of prism is, $\frac{dV}{dt}=-555\ in^3/min$ (The negative sign implies the volume decreases with time.)

Now, rate of change of height of prism = $\frac{dh}{dt}=?$

Length and width remains constant.

Now, we know that, volume of a rectangular prism is given as:

Volume = Length × width × Height

$V=Lwh\\\\V=10\times 16\times h\\\\V=160h$

Now, differentiating both sides with respect to time 't', we get:

$\frac{dV}{dt}=\frac{d}{dt}(160h)$

Plug in the given values and solve for $\frac{dh}{dt}$ . This gives,

$-555=160\times \frac{dh}{dt}\\\\\frac{dh}{dt}=\frac{-555}{160}\\\\\frac{dh}{dt}=-3.47\ in/min$

The negative sign implies the height decreases with time.

Therefore, the the rate of change, in inches per minute, of the height when the height is 3 inches is -3.47 inches per minute.

What is the product of the two binomials below (3A+4B)(3A-4B)

Mariulka [41]

Answer:

9A^2 - 16B^2.

Step-by-step explanation:

(3A+4B)(3A-4B) = 9A^2 + 12AB - 12AB - 16B^2 = 9A^2 - 16B^2.

Hope this helps!
