ANSWER: 312 3/8
So Volume is Length • Width • Height

So first we would put it into this formula:
8.5 • 5.25 • 7= 312.375, or, 312 3/8

Evaluate the expression for the given value of the variables.

Rudik [331]

Since c=15 and d=3, we replace the c and d variables with 15 and 3.

0.5x15-1.7x3

0.5x15=7.5

1.7x3=5.1

Now subtract.

7.5-5.1=2.4

Consider the following proability density function: f(x) = { kx. 0<= x< 2, k(4-x). 2<= x <=4, 0. otherwise. find the

Gnesinka [82]

The value of K for which f(x) is a valid probability density function is 1/4.

<h3>How to solve for the value of K</h3>

$\int\limits^4_0 {fx(x)} \, dx =1$

$\int\limits^2_0 {Kx} \, dx +\int\limits^4_2 {K(4-x)} \, dx =1$

$K[\frac{2^2}{2} -0]+[K[4(4-2)-(\frac{4^2}{2} -\frac{2^2}{2} )]=1$

open the equation

$K\frac{4}{2}+K[8 - (\frac{16}{2} -\frac{4}{2} )] = 1\\$

$2K+K[\frac{4}{2} ]=1$

2K + 2K = 1

4K = 1

divide through by 4

K = 1/4

In 4 minutes, a conveyor belt moves 800 pounds of recyclable aluminum from the delivery truck to a storage area. A smaller belt

kkurt [141]

Answer:

It takes 2 minutes 4 seconds to move the cans to storage area if both the belts are used.

Step-by-step explanation:

Given - In 4 minutes, a conveyor belt moves 800 pounds of recyclable

aluminum from the delivery truck to a storage area. A smaller belt

moves the same quantity of cans the same distance in 6 minutes.

To find - If both belts are used, find how long it takes to move the cans

to the storage area.

Proof -

Given that,

Larger belt take 4 minutes to transfer the aluminium from delivery truck to storage area.

⇒ Time taken by Larger belt = 4 min/ shifting

Also,

Smaller belt take 6 minutes to transfer the aluminium from delivery truck to storage area.

⇒ Time taken by Smaller belt = 6 min/ shifting

Now,

As we know that Time is inversely proportional to time, so

Rate of Larger Belt = $\frac{1}{4}$ shifting/min

Rate of Smaller Belt = $\frac{1}{6}$ shifting/min

Now,

Let us assume that , if both belts used then,

Total time taken = x min/shifting

Then, Rate = $\frac{1}{x}$ shifting/min

Now,

$\frac{1}{4}$ + $\frac{1}{6}$ = $\frac{1}{x}$

⇒ $\frac{6 + 4}{24} = \frac{1}{x}$

⇒ $\frac{10}{24} = \frac{1}{x}$

⇒10x = 24

⇒x = $\frac{24}{10}$ = 2.4 minutes

∴ we get

It takes 2 minutes 4 seconds to move the cans to storage area if both the belts are used.
