Answer:
95 and 2/5
Step-by-step explanation:
4/10= 2/5
Answer: 500
Step-by-step explanation: Multiply 2000/1 and 1/4. Cross cancel 2000 and make it 500, and cross cancel 4 and make it 1. When you multiply you will get 500.

Answer:
30+75x
Step-by-step explanation:
To find the answer, we must use the surface area to find the radius, and then double the radius to see if its within the acceptable range for the diameter.
The surface area of a circle can be found by this equation:
A = 4π (r²) , where A is surface area, and r is the radius.
Let's plug in 9π for A, and solve for the radius:
9π = 4π (r²) Divide both sides by 4π, the π's cancel out
9/4 = r²
Take the square root. Remember there's a square in the numerator and the denominator.
3/2 = r
r is equal to 3/2, or 1.5. Remember that the diameter is just the radius multiplied by 2.
d = 2r
d = (3/2) * 2 = 3
The diameter is 3, which is a bit higher than the range of regulation size. Therefore, the ball is not within range.
Answer:
54 kilometers per hour
step-by-step explanation:
according to rules:
1 km = 1000 meter
which means that 1 meter = 1/1000 km
1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]
which means that 1 second = 1/3600 hour
therefore, 1 kilometer/hour = (1/1000)/(1/3600)=3600/1000=18/5=3.6 kilometer/hour
thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.
15 meter/second= 15*3.6=54 kilometer/hour which is the required answer.
