Since the plane descends 1,300 feet per minute it would descend 19,500 feet after 15 minutes (1,300 x 15 = 19,500) Subtract this from the plane's initial altitude 32,000 and the new altitude will be 12,500. (32,000-19,500=12,500)
So for the first one what you did was wrong as in wrong formula.
Radius is 5cm as it is given and diameter is double the radius which is 10.
So r=5
And D=10.
For the second one the diameter is 16cm as it is given and radius is half the diameter,so half of 16 is 8cm right?
So r=8
And D=16
Answer:
Step-by-step explanation:
a) if she had 16 m of fencing
all possible outcomes
4 by 4
2 by 6
1 by 7
the greatest should be 4 by4
b) she could alter it to 2 by 6
Answer:
the probability that the student is a hostlier is 0.6923
Step-by-step explanation:
The computation of the probability that the student is a hostlier is shown below
= (0.60 × 0.30) ÷ (0.60 × 0.30) + (0.40 × 0.20)
= (0.18) ÷ (0.18 + 0.8)
= (0.18) ÷ (0.26)
= 0.6923
Hence the probability that the student is a hostlier is 0.6923
