Yes, correct

'total from other side'

MS....these questions are all pretty simple.....Have you TRIED to do any of them?   We are not here to do your homework!

From his bank statemnet ,

Noah starts with                    715.26

then he adds                         275.00

then he subtracts                   60.00

then subtracts a check for    410.21      

                                 result = ..........

Agree with asinus.....perhaps you meant  PICOGRAM

 picogram is a unit of mass equal to 000 000 000 001 grams symbol

.0073 gm /.000000000001 gm/pg                  = 7 300 000 000   pico gram   = 7.3 x 10 ⁹ pg

125 l / 1000 l/kl = ........ kl

Find radius using distance formula for the two given points

r = sqrt (61)

center (h,k) =   -1, 1

(x+1)² + (y-1)² = 61  this is the equation of the circle

       expand and arrange in the form requested in the Q to find ABCD to finish...........

Put in standard circle equation form    (x-h)^2 + (y-k)^2 = r^2

(x-5)^2      + (y+4)^2  =   - c  +25 + 16

      so    - c + 25 + 16 = 1^2

               -c = 1 -25-16

                 c = 40

100 C   = 212 F      (formula   F = 9/5 C  + 32    )

500 ml = .132086 gal

400 / .132086  = 3 028 bottles

400 * 3.8 * 2 = 3040       12 extra bottles

400*4 *2 = 3200 bottles

Substitute in each of the x,y points given in to the equation....

   you will then have two equations with two variables b and c that you can solve for c

Total from the backside (625) can be assumed to be checks I guess (there is no cash shown on the top line)

  so the subtotal is all checks that were deposited = 950

     this is NOT the final deposit amount because 80 dollars is withdrawn ('less cash received') for a final amount 870  (last line)

-1 to any even power is just '1'

so the first two are = 1

the third :  ( 2³)²  = 2^3*2 = 2⁶ = 64
