1:45pm and 3:15pm
Start at 1:45 in 15 min is
2:00 in 1 hour is
3:00 in 15 min is
3:15
so in 1 hour and 30 minutes
There are 14 students on 3 of the buses and 8 on the other
Answer:
312
Step-by-step explanation:
Let the attendance before the drop be x
Now we are given that attendance dropped 4% this year
So new attendance =
=
=
We are also given that attendance dropped 4% this year, to 300
So,
Hence the attendance before the drop was 312
1) If we let the lengths of the legs be x and 2x, then by the Pythagorean theorem,
This means that the length of the hypotenuse is:
2) (Diagram attached) We know that
(in cm)
3) From the Pythagorean identity,
4)
Answer :
The value of q for, the given quadratic equation is 40
Step-by-step explanation :
Given quadratic equation as :
x² - 14 x + q = 0
And , Difference between the roots of equation is 6
Let A , B be the roots of the equation
So, A - B = 6
The roots of the quadratic equation ax² + bx + c = 0 as can be find as :
x =
x =
or, x =
Or, x =
So , The roots are
A =
And B =
∵ The difference between the roots is 6
So, A - B = 6
Or, ( ) - ( ) = 6
Or, ( - 7 + 7 ) + 2 ( = 6
Or, 0 + 2 ( = 6
∴ 196 - 4 q = 36
or, 4 q = 196 - 36
or 4 q = 160
∴ q =
I.e q = 40
S0, The value of q = 40
Hence The value of q for, the given quadratic equation is 40 . Answer
