Answer:
A. 4/7
Step-by-step explanation:
If Susie has a bag with 9 hairpins, 7 pencils, 2 snacks, and 4 books, the ratio of books to pencils is 4/7 or 4:7.
4 books.
7 pencils.
You could combine the 4 and 7 getting, 4/7 or 4:7
Even though, there are more numbers, the question only asked for the ratio of books to pencils.
Answer: quadratic model, 0.866
Step-by-step explanation:
Answer:
system of equations are
Step-by-step explanation:
Let x = number of children's books sold,
and let y = the number of adult books sold
The library sells 376 books at its annual used-book sale
so, we get equation as
Children's books cost $4
So, total cost of children book is 4x
adult books cost $7
So, total cost of adult book is 7y
so, we get total cost is 4x+7y
he sale takes in a total of $2119
so, we get equation as
so,
system of equations are
Answer:
(-0.6)^3
Step-by-step explanation:
Here, we want to write the given expression in exponential terms
From what we have, there is a repetitive term
For example, if we had;
(x)(x)(x)
Exponentially, we will have this written as x^3
Using the above technique in what we have at hand
(-0.6)(-0.6)(-0.6) = (-0.6)^3
