The question is in the picture
SpyIntel [72]

Remark

Usually this is written in very simple terms. You could do it as a proportion, but it might be easier to see if you used Newton's formula twice.

Formula

F = m * a

m = mass, F = force, a = accelerationn

Givens

F1 = 70 N

a1 = 6.5 m/s^2

m = ?

F2 = ??

m = ?

a2 = 8 m/s^2

Step One

Solve for m

F1 = m * a1              Substitute the values

70 = m *  6.5           Divide by 6.5

70/6.5 = m

10.77 kg = m

Step Two

Solve for F2

m = 10.77 kg

a = 8

F2 = ??

F2 = m * a2

F2 = 10.77 * 8

F2 = 86.154

Answer: C rounded to the nearest 1/100

Three numbers X, Y, and Z are in the ratio 2:7:8. If 12 is subtracted from Y, then three numbers form a geometric sequence (in t
melomori [17]

Answer:

  (X, Y, Z) = (8, 28, 32)

Step-by-step explanation:

The ratio units will form a geometric sequence if the middle one is the square root of the first and last:

  Y' = √(2·8) = 4

To get this value from 7, we must subtract 3. In the real sequence we must subtract 12, so each "ratio unit" must stand for 12/3 = 4 real units, and the real numbers X, Y, Z are 2·4 = 8, 7·4 = 28, 8·4 = 32.

  (X, Y, Z) = (8, 28, 32)

  (X, Y-12, Z) = (8, 16, 32) . . . . a geometric sequence with a ratio of 2
