The best thing to do here is to divide $4.85 by 10, and then multiply it by 2.5. $4.85/10= $0.48. $0.48x2.5= $1.20
Therefore,the discount is $1.20, you've then got to subtract this from $4.85. $4.85-$1.20= $3.65
$3.65 is the sale price of the pizza.
Hope this helps :)
Answer:Percent of the teachers surveyed had neither high blood pressure nor heart trouble = 24.99%
Step-by-step explanation:
We are given the following in the question:
Number of teachers surveyed = 120
Number of teachers had high blood pressure = 70
Percentage of teachers had high blood pressure =
Number of teachers had heart trouble = 40
Percentage of teachers had heart trouble =
Number of teachers had both high blood pressure and heart trouble = 20
Percentage of teachers had both high blood pressure and heart trouble =
Percent of the teachers surveyed had high blood pressure or heart trouble = Percent of teachers had high blood pressure +Percent of teachers had heart trouble - Percent of teachers had both high blood pressure and heart trouble
Percent of the teachers surveyed had neither high blood pressure nor heart trouble
= 100% - Percent of the teachers surveyed had high blood pressure or heart trouble

1) you can expand the brackets, simplify, set the equation = 0 and then do a double bracket factorisation.
2)
therefore Josh's solution is wrong asx = 7 and x= -1
Answer:
Its degree can be at least 1970
Step-by-step explanation:
for each root of the form √q, where q is not a square, we have a root -√q. Therefore, we need to find, among the numbers below to 1000, how many sqaures there are.
Since √1000 = 31.6, we have a total of 30 squares:
2², 3², 4², ...., 30², 31²
Each square gives one root and the non squares (there are 1000-30 = 970 of them) gives 2 roots (one for them and one for the opposite). Hence the smallest degree a rational polynomial can have is
970*2 + 30 = 1970
