Answer: 960

Step-by-step explanation:

The first digit can be filled by letter A to F= 6 ways

The second digit will be filled by letter A to F or numeral 0-9= 6+10= 16 ways

The third digit will be filled by number 0 to 9= 10 ways

So total 3 digit hexadecimals are= 6 x 16 x 10 = 960

Not much can be done without knowing what \mathbf F(x,y,z) is, but at the least we can set up the integral.

First parameterize the pieces of the contour:

C_1:\mathbf r_1(t_1)=(2\sin t_1,2\cos t_1,0)
C_2:\mathbf r_2(t_2)=(1-t_2)(2,0,0)+t_2(3,3,3)=(2+t_2, 3t_2, 3t_2)

where 0\le t_1\le\dfrac\pi2 and 0\le t_2\le1. You have

\mathrm d\mathbf r_1=(2\cos t_1,-2\sin t_1,0)\,\mathrm dt_1
\mathrm d\mathbf r_2=(1,3,3)\,\mathrm dt_2

and so the work is given by the integral

\displaystyle\int_C\mathbf F(x,y,z)\cdot\mathrm d\mathbf r
=\displaystyle\int_0^{\pi/2}\mathbf F(2\sin t_1,2\cos t_1,0)\cdot(2\cos t_1,-2\sin t_1,0)\,\mathrm dt_1
{}\displaystyle\,\,\,\,\,\,\,\,+\int_0^1\mathbf F(2+t_2,3t_2,3t_2)\cdot(1,3,3)\,\mathrm dt_2

I am greater than 54 fewer tens than 90?
Lubov Fominskaja [6]
In all cases, we will let x represent the number.
1) 54 tens = 540
90 - 540 = -450
x > -450

2) x < 36 and x > 24
24 < x < 36

3) 8 tens and 5 ones = 80 + 5 = 85
x > 85

4) x > 27
x < 33
And the value in the ones place is less than the value in the tens place, so
30 ≤ x ≤ 32
