A book with a yellow sticker costs 50cents more than double a book wit3a red sticker

Mathematics
1 answer:
navik [9.2K]3 years ago
8 0

Answer:

50b>100b

Step-by-step explanation:

the book (b) is your variable in this case (a variable is just an item and im using b because it stands for books lol)

the book costs 50 cents, so we are going to put 50 cents in front of b(the books) so like this---->  50b: this reads as "the books are 50 cents."

now, the "more than" always means this sign ">"

and here's the tricky part, since it says " double a book with a red sticker." you're going to want to multiply ( 50*2=100), and we do this because of the word "double" (double means two) this is how you would write this scenario.

now im not sure if you wanted me to solve for it, but if curious you would just have to divide. the 50 and the 100 to get an answer.

Answer:

A, 152 cm.

Step-by-step explanation:

A rectangular pyramid has a volume equation of

V = (lwh)/3.

Therefore, when we plug the values in:

[(7)(5)(13)]/3 = V

V = 455/3

V = 151.666667

V is approximately equal to 152 cm^3.

I hope this helped! :)

The number of bacteria in a certain culture doubled every hour. If there were 30 bacteria present in the culture initially, how
vichka [17]

Answer:

The number of bacteria after 8th will be 3840

Step-by-step explanation:

Given the initially 30 bacteria present in the culture.

Also, the number of bacteria got doubled every hour.

So, using the equation

A=A_0r^{n-1}

Where A is number of bacteria after n hours.

A_0 is bacteria present initially.

r is the common ration, in our problem it is given that bacteria doubles every hour. So, r=2

And n is the number of hours. In our problem we need amount of bacteria at the end of 8th hours. So, n=8

Plugging values in the formula we get,

A=30(2)^{8-1}\\A=30\times 2^7\\A=30\times 128\\A=3840

So, number of bacteria after 8th will be 3840
