Answer with Step-by-step explanation:
Since we have given that
Some students in my class use e-mail.
It is a type of 'E' statements.
Its negation should be No students in my class use e-mail.
Because if we use "Some students in my class do not use e-mail”.
It also implies some students in my class still use e-mail.
But negation contains only opposite of given statement.
So, Some students in my class do not use e-mail” is not true.
I think is 70 because you first sum 18 + 6, then your answer is 24 and you subtract 90 - 24 because the triangle is a right angle that is 90 degrees. That got me 66 and I round it to the nearest tenth and I get 70.
Answer:
39 touchdowns and 13 fieldgoals
Step-by-step explanation:
Let t= touchdowns
f = fieldgoals
They scored 35 times
t+f = 35
Touchdown is 7 pts and fieldgoal is 3 pt
7t+3f = 193
Multiply the first equation by-7
-7t -7f =-245
Add this to the second equation
-7t -7f =-245
7t+3f = 193
----------------------
-4f =-52
Divide by -4
-4f/-4 = -52/-4
f = 13
Now we can find t
t+f = 35
t+13 = 52
Subtract 13 from each side
t+13-13 =52-13
t =39
Set the formula up and insert the stuff
=16.56 if you use the A=PIr^2
