Answer:
They traveled 72 miles in all.
Step-by-step explanation:
Answer:
72mm^2 (72 mm squared)
Step-by-step explanation:
so i would work out the little triangle which is 8x6/2=<em><u>24m</u></em>m^2
then do 24x8/2 which is <u><em>96m</em></u>m^2
then take away 24 from 96 which gives the answer of <u><em>72mm^2</em></u>
Answer:
Since b^2 -4ac = -31 we have 2 complex roots
Step-by-step explanation:
2x^2+ 5x+7=0
The discriminant is b^2 -4ac
when the equation is ax^2 +bx+c
so a =2 b=5 and c=7
(5)^2 - 4(2)(7)
25 - 56
-31
If b^2 -4ac > 0 we have 2 real distinct roots
If b^2 -4ac = 0 we have one real root
If b^2 -4ac < 0 we have two complex root
Since b^2 -4ac = -31 we have 2 complex roots
Number of students in senior class is 130
<em><u>Solution:</u></em>
Given that Every student in the senior class is taking history or science
85 of them taking both history and science
106 seniors takes history
109 seniors takes science
To find: number of students in senior class
Let A be the set of the students of the senior class that take history
Let B be the set of students of senior class that they science
The number of students in senior class is given by:
Where,
A = 106 and B = 109 and |A n B| = 85
Thus number of students in senior class is 130
