Answer: The whole area of all the wood is 36
Step-by-step explanation:
The formula for area of a rectangle is length times width. A=lw
You plug the numbers into the formula: A=2*3 = 6
The area for one piece of wood is 6 ft
If you take multiply one area of wood by the amount of wood - you get the whole area amount of all the wood. So 6*6 = 36.
The seamstress will need 12 inches of special fabric.
#3) since angle ABC is 115 degrees, to find EBC you simply have to subtract 115 from 90 and the answer is 25 degrees.
#4)DGJ would be 30 degrees because you take 70 minus 40.
#5) a 90 degree angle.
Answer:
64 in³
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( where s is the length of the side )
Given
area = 16, then
s² = 16 ( take the square root of both sides )
s = 
= 4 , thus
V = 4³ = 4 × 4 × 4 = 16 × 4 = 64 in³
Answer:
c. 0.3421
Step-by-step explanation:
The computation of the probability of selecting the biased coin is shown below:
The probability of any coin selected is 1 ÷ 2
The probability in the case when the biased coin chosen & wins 1 ÷ 2 (1 - 0.74)
And, the win probability is 1 ÷ 2 (1 - 0.74) + 1 ÷ 2 (1 - 0.5)
Now the probability of biased or win is
= {1 ÷ 2 (1 - 0.74)} ÷ { 1 ÷ 2 (1 - 0.74) + 1 ÷ 2 (1 - 0.5)}
= 0.13 ÷ 0.38
= 0.3421
Hence, the correct option is c. 0.3421
