For 1. The bike is going 24 miles in 3 hours. To figure out how many miles it went in 1 hour you divide 24/3 which is 8 miles. If the bike went 8 miles per hour then you may now multiply it by 10 to find the total mileage in 10 hours. 10x8=80

( 1 - x/100)^20  = 3843/55550

Taking logs

20 log (1 - x/100) = log (3843/55550)

log ( 1 - x/100) =  log (3843/55550)  / 20 = -0.0580007
1 - x/100 = 10^-0.0580007 = 0.875
x / 100 = 1 - 0.875 = 0.125
x = 12.5 Answer

The area of the rhombus is 540 cm2; the length of one of its diagonals is 4.5 dm. What is the distance between the point of inte
11111nata11111 [884]

Area of rhombus = \frac{xy}{2}

where x and y are diagonals.

Given length of one diagonal is 4.5 dm

So, let x= 4.5dm

1 dm = 10 cm

4.5dm= 45cm

area = \frac{xy}{2}

so, 540 = \frac{45y}{2}

y = 24 cm

The two diagonals are x= 45cm and y = 24cm

Since diagonals bisect each other, we get 22.5cm and 12cm

Using right triangle formula

\frac{1}{r^{2} } = \frac{1}{22.5^{2}} + \frac{1}{12^{2}}

\frac{1}{r^{2} } =\frac{12^{2}+22.5^{2}}{22.5^{2}*12^{2}}

r^{2} = \frac{22.5^{2} *12^{2}}{12^{2}+22.5^{2}}

r = 10.588cm

Distance of center to the side = \frac{10.588}{2}  = 5.294 cm
