Answer
A. -30 points
B. 60 points
Step-by-step explanation:
20 points for correct answer and 10 points deducted for wrong answer
Each deduction is -10 while each correct answer gives + 20
4 questions correctly and 11 incorrectly
= 4(20) + 11(-10)
= 80-110 = -30 points
Second round
7 correct, 8 incorrect
= 7(20) - 8(10)
= 140-80 = 60 points
L=25
If the length is 25 yards then you use 50 yards of fencing for the length, this leaves ten yards for each width of fencing each.
10 yards is 15 yards less than 25 yards showing that this is the correct answer.
Answer:
2i-3
Step-by-step explanation:
2(x+3)²=-8
(x+3)²=-4
x+3=2i
x=2i-3
Answer:
V = 24pi
or 75.36 ( using 3.14 for pi)
or 75.39822369 ( using the pi button)
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the radius and the height
V = pi (2)^2 * 6
V = pi 4*6
V = 24 pi
If we approximate pi by 3.14
V = 3.14 * 24 = 75.36
If we use the pi button
V =75.39822369
