Answer:
Weight of Large Box = 18.5 kg
Weight of Large Box = 13.25 kg
Step-by-step explanation:
<u>Given:</u>
There are two types of boxes i.e. Large and Small
Let the weight of Large boxes = L kg
Let the weight of Small boxes = S kg
As per given statement:
- A delivery of eight large boxes and four small boxes has a total weight of two hundred and one kilograms.
Writing equation for above:
....... (1)
- A delivery of three large boxes and two small boxes has a total weight of eighty two kilograms.
Writing equation for above:

Now, by solving the equations (1) and (2), we can get the values of L and S.
<em>Multiplying equation (2) with 2 and subtracting from equation (1):</em>
-

-

--------------------

L = 18.5 Kg
Putting value of L in equation (1):

So, the answer is:
Weight of Large Box = 18.5 kg
Weight of Large Box = 13.25 kg
Answer:
The ball will take 4.05 seconds to hit the ground.
Step-by-step explanation:
we have

This is a quadratic equation (vertical parabola) open down
The vertex is a maximum
we know that
The ball hit the ground when h=0
Solve the quadratic equation
For h=0

The formula to solve a quadratic equation of the form
is equal to

in this problem we have
so

substitute in the formula


---> the time cannot be a negative number

therefore
The ball will take 4.05 seconds to hit the ground.
Answer:
A straight angle
Step-by-step explanation:
90 + 90= 180
Unit rate = 3/8 : 1/6
We can also write this as:
3/8 / 1/6
Flip the 2nd fraction and multiply:
3/8 * 6/1
Multiply the numerators and denominators together:
18/8
Simplify by dividing the numerator and denominaotr by 2:
18 / 2 = 9
8 / 2 = 4
So we have:
9/4
