I believed it is "401"
1-9 = 9 digits
10-99 = 90 which is 180
100-200 = 100 which is 300 digits
9+180= 189
1392-189= 1203
1200÷300=400 which 1200 digits
401 is the 1392 number scanned
There are 14 marbles in the bag, and we either want to get 0 or 1 cracked one (out of 2 cracked marbles) in 4 draws. Since there are 12 uncracked marbles and 2 cracked ones:
To get 0 cracked marbles, there are 12C4 ways (to draw 4 marbles out of the 12 uncracked ones only). 12C4 = 495 ways
To get 1 cracked marble, we need 3 to be from the 12 uncracked ones, and 1 from the 2 cracked ones. This means there are 12C3 x 2C1 = 440 ways
So the total number of ways is 495 + 440 = 935 ways.
First multiply the big numbers. 3*1.20= ($3.60) and 5*1.20= ($6)
Now the fractions, 1/12 would equal 10 cents. 5/12 + 1/12= 6/12 which would also equal (60 cents). 3.60+6.00+.60= $10.20
You have that the scale factor is 8 and the length of the figure is 10 yards. Therefore, to solve this exercise, and calculate the length of the image, you must follow the proccedure below:
1. If the scale factor is 8, this means that lenght of the image is 8 times bigger.
2. Keeping this on mind, you only have to multiply 8 by 10 yards, as below:
Length of the image=8x10 yards
Length of the image=80 yards
3. Therefore, the answer is the option C:
C. 80 yd
