If the parallelogram floor needs a base of 16 feet,what will the height of the floor be

nydimaria [60]

Answer:

See Explanation

Step-by-step explanation:

<em>The question is incomplete because the area of the parallelogram is missing. However, the following will guide you in answering the question</em>

Given

$Base = 16\ ft$

Required

Determine the Height

Area of a Parallelogram is:

$Area = Base * Height$

Make Height the subject

$Height = \frac{Area}{Base}$

Substitute 16 for Base

$Height = \frac{Area}{16}$

This implies that you divide the value of area by 16 to get the height of the parallelogram.

Take for instance;

$Area = 64ft\²$

The height would be

$Height = \frac{64}{16}$

$Height = 4\ ft$

$Area = 80ft\²$

The height would be

$Height = \frac{80}{16}$

$Height = 5\ ft$

Rei is barricading a door to stop a horde of zombies. She stacks boxes of books on a table in front of the door. Each box weighs

Alinara [238K]

Answer: The answer is $\textup{W}=70+30x.$

Step-by-step explanation: Given that Rei is barricading a door to stop a horde of zombies by satcking boxes of books on a table in front of the door.

The weight of each box is 30 kilograms and the weight of the table with 8 boxes on the top is 310 kilograms.

So, if 'g' denotes the weight of the table alone, then we have

$\textup{g}+8\times 30=310\\\\\Rightarrow \textup{g}+240=310\\\\\Rightarrow \textup{g}=310-240\\\\\Rightarrow \textup{g}=70.$

Therefore, the weight of the table without boxes is 70 kilograms.

Now, if 'W' is the total weight of the barricade, then it can be written as a function of 'x', the number of boxes Rei stacks on the table. The expression is as follows -

$\textup{total weight of the barricade}=\textup{weight of the table alone}+30\times \textup{number of boxes}.$

Thus, the required function is

$\textup{W}=70+30x.$
