Answer:
20,000m²
Step-by-step explanation:
If they jog 12 km/h for half an hour, they have covered.
12 X 0.5 = 6km in 10 circuits. Making 1 perimeter
6 / 10 =0.6 km (600 m).
To determine area we need to convert this perimeter to length and width. We know that it is a rectangle, with 2 equal widths and 2 equal lengths, and the length is twice the width.
So L = 2W
Perimeter = 2W + 2L
600 m = 2W + 2(2W)
600 m = 6W
W = 100 m
L = 200 m
Area = 100 X 200 = 20,000 m²
Answer:$90
Step-by-step explanation:
360/4=90
Answer:
What?
Step-by-step explanation:
A bicyclist travels at a constant speed of 12 miles per hour for a total of 45 minutes
Domain x is number of hours
Range y is distance traveled
speed = 12 miles per hour
time = 45 minutes =
= 0.75 hours
We know distance formula
Distance = speed * time
Distance = 12 * 0.75= 9 miles
Number of hours x is 0 to 0.75 hours
So domain is {
}
Distance is 0 to 9 miles
So range is {
}
Answer:
8
Step-by-step explanation:
Note that 2 divides into 8 evenly, yielding the quotient 4. 8 is the LCD. To combine 3/8 and 11/2, we would rewrite 11/2 as
4·11
------ = 44/8
4·2
and then combine 44/8 with 3/8. The sum would be 47/8.
In summary, the LCD of 3/8 and 11/2 is 8; 3/8 stays as is and 11/2 is rewritten by mult. numerator and denominator by 4 each.
