Answer: 15
Step-by-step explanation:
4/20 is your ratio. Simplify it and it'd be 1/5. This means in 1 mile has been walked in 5 minutes. 3 x 5 is 15, so it took Susan 15 minutes.
Francisco <span>has simplified to the quantity of x to the one half power, over x to the three eighteenth power.
(x^1/2) / (x^3/18)
x^(1/2-3/18)
x^1/3
Ryan has simplified to the twenty seventh root of the quantity of x to the second times x to the third times x to the fourth.

Mean: 29
23 + 25 + 25 + 27 + 32 + 35 + 36 = 203
203 / 7 = 29
Median: 27

Answer:
292 feet
Step-by-step explanation:
If Emily walked round the two rectangular parks, she walked round the perimeter of the parks.
the total distance she walked can be determined by calculating the perimeter of each of the park and adding the perimeters together
Perimeter of a rectangle = 2 x ( length + breadth)
Perimeter of the first park = 2 x (54 ft + 38 ft) = 184 ft
Perimeter of the second park = 2x (32 + 22) = 108 ft
Sum of the perimeters = 184 ft + 108 ft = 292 ft
