Answer:
A. 1ft
Step-by-step explanation:
1 x 1 = 1 squared
So 1 foot x 1 foot = 1 square foot
Answer:
Area= 615 ft²
Step-by-step explanation:
Apply the formula for area of a circle to find the area watered when a sprinkler covers a full circle
Area of a circle= 
r= 14ft
Area= 3.14 × 14²
Area=615.44 ft²
Area= 615 ft²
Answer:
133.33 mph
Step-by-step explanation:
The small trick is to notice the time. Is it 8:00 AM the same day. We don't know, but we will assume it is.
So the truck was on the road for 2 hours.
The car was on the road for 2 - 1/2 = 1 1/2 = 1.5 hours.
The distance travelled was 200 miles
Solution
d = r * t
200 = r * 1.5
200/1.5 = r
r = 133.33 miles / hour
The noise you hear is a siren trying to catch up to the car.
Answer:
₹4064
Step-by-step explanation:
Given data
P= ₹4000
r= 8%
t= 2 years
Required
The final amount A
we will apply the simple interest formula
A=P(1+rt)
substitute
A= 4000(1+0.08*2)
A= 4000(1+0.16)
A= 4000*1.016
A= ₹4064
Hence the amount is ₹4064
Answer: speed other the slower train is 46 mph.
speed other the faster train is 56 mph.
Step-by-step explanation:
Let x represent the speed of the slower train. One train travels 10 mph faster than the other. This means that the speed of the faster train is (x + 10) mph.
In 4.5 hours, the trains are 459 miles apart. This means that the total distance travelled by both trains in 4.5 hours is 459 miles.
Distance = speed × time
Distance travelled by the slower train in 4.5 hours is
4.5 × x = 4.5x
Distance travelled by the faster train in 4.5 hours is
4.5(x + 10) = 4.5x + 45
Since the total distance covered is 459 miles, therefore,
4.5x + 4.5x + 45 = 459
9x = 459 - 45 = 414
x = 414/9
x = 46 mph
Speed of the faster train is
46 + 10 = 56 mph
