An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms.
¾ of this weight is metal, and the rest is wood.


How much does the wood part of the sculpture weigh?

Answers

Answer:

Given is a sculpture that is built up of metal and wood, and the weight of this sculpture is 14.9 kilograms.

It says that three-fourth of the total weight is metal and says to find the weight of wooden part.

We can find the weight of metal part and then subtract it from the total weight to calculate the answer.

Step-by-step explanation:

Total weight = 14.9 kilograms.

Metal part = three-fourth of total weight =

Wooden part = 14.9 - 11.175 = 3.725 kilograms.

Hence, the wooden part is 3.725 kilograms.

I think you would have to convert 14.9 kg to fraction and multiply by 3/4 try it

If the perimeter of a regular pentagon can be expressed as 10s - 20, determine the length of each side.

50 s - 100
5 s - 10
s - 2
2 s - 4

Answers

Answer:

2 s - 4

Step-by-step explanation:

A Regular pentagon means that it has 5 evenly lengthen sides. In other words, the shape with 5 sides has lengths are equal to each other.  

Because the total perimeter as mentioned of the pentagon is 10s - 20,  

dividing it by 5 should find the length of each side!

Equation: (10s - 20) / 5

Once you finish dividing each digit inside the bracket you are done!

= 2s - 4

So that leaves us with 2s-4

Answer:

2 s - 4

Answer:

I think it is by multiplying by 2.

Step-by-step explanation:

Even if it depends on the x, the constant of proportionality just goes by the multiple of 2 as you can see on the graph.

For example, the point that's on ( 2, y) on the graph is the start of it's proportional relationship that is on the line. Here is an example of how it is proportional:

5. Using the equation y=2x+5, construct a table and graph the line

Answers

Step-by-step explanation:

What you are going to do is for each value of x (which is the value to the right on the table) you will find the Y value.

So for X = 0

y = 2(0)+5 = 5

x = 1

y = 2(1)+5 = 7

x = 3

y = 2(3)+5 = 11

x = 5

y = 2(5)+5 = 15

x = 10

y = 2(10)+5 = 25

Now for what you do is place the correspanding value into the graph.

(x,y) = (0,5), (1,7), (3,11),(5,15),(10,25)
