Which of these numbers has the smallest value? Nine tenths, twenty hundredths, two hundredths, or forty five thousandths
victus00 [196]
Nine tenths = 0.9
Twenty hundredths is 0.2
Two hundredths is 0.02
Forty five thousandths is 0.045

The number with the smallest value is 0.02, or two hundredths.

The inequality that correctly compares thirty five and thirty seven hundredths (35.37) to thirty five and ninety four thousandths (35.094) is B. 35.37 > 35.094, because 35.37 is greater than 35.094.

25 - [2 x (18÷ 6) + 1]
25 - [2 x (3) + 1]
25 - [6 + 1]
25 - [7]
18
25 - [2 x (18 ÷ 6) + 1] = 18

which of the following is a result of shiftinga circle with equation (×-2)+(y-3)^2= 25 to the left 2 unit ?​
Paha777 [63]

Answer:

x^2+(y-1)^2=25

Step-by-step explanation:

eqn of circle : (x-h)^2+(y-k)^2=r^2

center of circle = (h,k)

hence, the center of the current circle is (2,3)

moving 2 units to the left would make the center (0,1)

the radius would remain the same (5) , hence the new eqn would be

(x-0)^2+(y-1)^2=25

x^2+(y-1)^2=25
