Answer:
Option D is the Answer
Step-by-step explanation:
Given : Benni wants to divide 48.6 by 0.7.
To find : In order to estimate the quotient, which is the best expression to use?
Solution :
In order to estimate i.e. an approximate calculation we round the numbers,
48.6 as tenth place is > 5 then it round completely
0.7 as tenth place is > 5 then it round completely
So the estimated expression is given by,
Therefore, option D is correct.
Answer:
7 books
Step-by-step explanation:
make an equation
x = # of books each book is $4 so its 4x
the shipping fee no matter how many books he buys will be $2 so it's just 2
the equation looks like this:
4x + 2 = 30
we set equal to 30 cuz he can't spend more than $30
solve for x
4x = 30 -2
4x = 28
x = 7
Brett can buy no more than 7 books.
Fron the table given:
A3 = 112,
A8 = - 3,584
An = A1 *r ^ (n-1)
=> A3 = A1 (r^2) = 112
A8 = A1(r^7) = - 3,584
=> - 3584 / 112 = (r^7) / (r^2)
=> (r^5) = - 32
=> r = - 2
=> A1 (- 2)^2 = 112
=> A1 = 112 / 4 = 28
Answer: a1 = 28
