V=(h)(pi)(r^2)
say pi=3.14
h=15
d/2=r=4/2=2
so
v=(15)(3.14)(2)^2
v=(15)(3.14)(4)
v=(60)(3.14)
v=188.4
so answer is D
Answer:
-4
Step-by-step explanation:
What I did was multiply 9/1 with 2/3 giving us 18/3 which simplifies into 6. Then what we do is subtract 2 with 6 giving us -4.
We can make 0.7033 an improper fraction by multiplying it by 10,000 to get:
7033/10,000
Note that this cannot be a mixed number because 10,000, the denominator, is greater than 7033, the numerator.
You may have misspelled or typoed the question, or the question might be wrong, because 0.7033 can't be written as a mixed number.
Answer: The distance between them is 230.65 miles.
Step-by-step explanation:
Since we have given that
Speed of plane A (b) = 200 miles per hour
Speed of plane B (c) = 300 miles per hour
Angle between them = 50°
So,
We will use the "Cosine formula", we get
So, distance between the two planes after one hour will be
So, the distance between them is 230.65 miles.
Step-by-step explanation:
- 4x+5= 20
- 4x=20-5
- 4x= 15
- x= 15/4
therefore the answer is option
b) X= 15/4
