Let the original price of the book be x. If, after a 33% markup on the initial price, the student had to pay 115.00 for it, then we can calculate x as:
(1 + 33%)(x) = 115
1.33x = 115
x = 115/1.33 = 86.47
This means that the bookstore paid $86.47 for the book.
Answer- b+t=90 (or bb + tt = 90 ignore if this was a mistake)
If we know that 90 is an absolute total, that will go behind the equal sign
?=90;
We know that we can make any mixture of burritos or tacos, but they have to equal up to ninety. As you stated bb= burritos and tt= tacos. (If that is a mistake, instead of putting bb or tt, just put the single letter b or t)
This means our equation would have to have a certain number times burritos and a certain number times tacos that equal 90.
Our equation should look a little like this
(number of burritos ) + (number of tacos) = 90
b + t =90 or with your values bb+tt=90
HOPE THIS HELPS & GOOD LUCK

Solution :
Given that :
The radius of circle A = 6 cm
The radius of circle C = 4 cm
In circle A

The length of arc EF = 

= 14.653 cm
In circle C

The length of arc GH = 

= 9.769 cm
Therefore,
The length of EF is 14.653 cm
The length of GH is 9.769 cm
The length of EF is 1.5 times the length of GH
i.e. 14.653 = 1.5 x 9.769
14.653 = 14.653
Hence proved.
Answer:
Absolute minimum = 7
Step-by-step explanation:
We are given graph of f'(x). f(0)=7
We need to find the absolute minimum value of f(x) over interval [-3,0]
First we will see the graph of f'(x) over interval [-3.0]
f'(-3)=3
f'(0)=0
Thus, f'(x) is decreasing
x=0 is critical point of the function f(x) because f'(0)=0
We will get absolute maximum/minimum at x=0. f(x) >0
Hence, f(0) is absolute minimum at x=0 , Absolute minimum = 7
