Answer:
The total surface area of this object is 510 cm^2.
Step-by-step explanation:
Here L = 12 cm, W = 7 cm and H = 9 cm.
There are 2 panels 12 by 9 cm, 2 panels 12 by 7 cm, and 2 panels 7 by 9 cm. The combined areas are:
2(108 cm^2) + 2(84 cm^2) + 2( 63 cm^2) = 510 cm^2 total area
Answer:
16.36%
dependent
Step-by-step explanation:
If we choose a crayon, then another crayon without putting the first one back in the supplies box, that means the event is dependent. The keyword to find whether some events dependent is " without putting back" because that means the first pick will reduce the number of crayons pool for the second pick.
There are 3 + 2 + 6 = 11 total crayons. There are 6 blue and 3 red crayons. The probability for picking blue then red crayon will be:
6/11 * 3/10 = 18/110= 0.163636 = 16.36%
86%, 3/4, 0.682, 0.67, 5/8, 0.41
^ I converted the above to decimals first and then arranged them that way.
1/20 = 0.05 x 100 = 5%
