Answer: 315 miles
Step-by-step explanation:
let onward speed = x mph, then distance = 7x
return speed = (x+18) mph, (same) distance = 5(x+18)
equating the two,
7x = 5(x+18)
2x = 90 ==> x = 45 mph
so distance = 7*45 = 315 miles
Answer:
13%
Step-by-step explanation:
Given the two way frequency table :
Country Music Rock Total
West 26 15 41
East 24 22 46
South 7 33 40
North 41 25 66
Total 98 95 193
From. The table :
n(West n Country music) = 26
n(Total) = 193
P(West n Country music) = n(West n Country music) / n(Total)
P(West n Country music) = 26 / 193
= 0.1347
= 13.47%
= 13%
We use the formula Area = 1/2 bc sin A = 1/2 * 2 * √2 * sin 60
A = √2 * √3 / 2
= √6/ 2 (answer)
