The formula to find density is Mass/Volume

We have
Density = 7.8 \frac{g}{cm^{3}}
Volume = 10504  cm^{3}

Hence
Mass = 7.8×10504 = 81931.2 gram

You have 2 job offers with the following options. Option 1: You are paid $30
kozerog [31]

Answer:

It takes 6 hours for both to reach an equal paid.

Step-by-step explanation:

You have to form an expressions in terms of x where x determine the number of hours :

Option 1,

$(30 + 9x)

Option 2,

$(14x)

Next, you have to compare it since they want to find out how many hours they work until they reach the same amount :

30 + 9x = 14x

30 = 14x - 9x

30 = 5x

5x = 30

x = 30÷5

x = 6

Tom has read the first 40 pages of a book. He plans to read another 12 pages each day Write an equation that represents the rela
DaniilM [7]

Algebra

The  equation that represents the relationship between , and the number of days he has been reading , d is p = 40 + (12 × d)

Step-by-step explanation:

Tom has read the first 40 pages of a book.

He plans to read another 12 pages each day

Since the total number of pages is p

And the Number of days required to read the book is d

if Tom read 12 pages per day, then in d days he would read 12 × d pages

h/e has already read 40 pages of the book

Then total pages of the book

p = 40 + (12 × d)

Hence, The  equation that represents the relationship between , and the number of days he has been reading , d is p = 40 + (12 × d)

Aidan has 20 ft of fence with which to build a rectangular dog run. What is the maximum area he can enclose?
butalik [34]
Assuming this Fence enclosment will be in the shape of a rectangle we will use the equation used to find the area of a rectangle, b×h=a

Using this formula we then must pick out factors used to create, in which the perimeter will add up to 20

·5,5,5,5 (25)
·8,2,8,2 (16)
·6,4,6,4 (24)


using this we can learn<span> that the maximum area that can be exclosed by this is 25, because the 2 perimiter lengths that define this rectangle would be 5 and 5.

</span>b(5)×h(5)=25(a)

therefore, your answer is 25 Units
