Answer:
10408 ft
Step-by-step explanation:
convert miles to ft
4 miles/hr * 5280 ft/ mile = 21120 ft/hr
convert hr to min
21120 ft/hr * 1hr/60 min = 352 ft/ min
multiply by 40 minutes
352 ft/min * 40 min =14080 ft
I believe it's 5,6
Hope this helped!
H = 70ft.
P = 35ft.
B = ?
H^2 = P^2 + B^2
70×70 = (35×35) + B^2
B^2 = 4900-1225
B = √3675
B = 35√3 ft.
Answer:
Step-by-step explanation:

From the initial condition,

So we have that 
We are given with an initial deposit of $20,000 and a future worth of <span>$35,000. In this case, we are asked for the return of income (ROI) of the investment. in this case, we assume the number of years equal to 1. hence,
</span>$35,000 = <span>$20,000* (1+i) ^1
</span>i or ROI then is equal to 0.75
